What are the benefits of woodworking dusters?What are the pros and cons of household dust collectors

A dust collection hood is set up in each ash place, and the dust-containing gas is transported to the dust removal device through the pipeline gas path, in which the dust is collected in the dust removal device after the gas-solid separation is carried out, and the clean gas is introduced into the main pipe or directly discharged into the whole set of equipment into the atmosphere, that is, the dust removal system, and the dust collector is an important part of the system. From the perspective of ventilation and dust removal, dust is all solid small particles that can float in the air for a long time, and is a dispersion system, called aerosol, in which air is the dispersed medium and solid particles are the dispersed phase. A dust collector is a device that separates these small solid particles from aerosols.

The dust collector is a good helper in cleaning, so what are the advantages and disadvantages of the dust collector?pchouse takes you to find out. 1. The advantages of the dust collector have high purification efficiency, and the electrostatic precipitator can improve the dust removal efficiency by lengthening the length of the electric field, increasing the effective flow area of the electric field, improving the control quality of the controller, and quenching and tempering the flue gas, so as to meet the required dust removal efficiency.

For conventional electrostatic precipitators, the dust removal efficiency is generally higher than 99% during normal operation, and fine-grained powder above microns can be popularized. The flue gas treatment capacity is large. The electrostatic precipitator is easy to modularize in structure, so it can realize the large-scale installation.

The maximum electric field cross-sectional area of a single electrostatic precipitator reaches 400 square meters. 2. The shortcomings of the dust collector The equipment is relatively complex, which requires a high level of equipment dispatch, installation and maintenance managementThere are certain requirements for the specific resistance of dust, so there is a certain selectivity for dust, and all dust can not obtain high purification efficiencyAffected by the operating conditions such as gas body temperature and temperature, the same kind of dust is operated at different temperatures and humidity, and the effect obtained is different, and some dust works very well at a certain temperature and humidity, and the electrostatic precipitator can hardly be used due to the change of dust resistance at another temperature and humidity.

In the era of the developed Internet, everyone will look at the evaluation on the Internet to do their homework before buying anything, and household vacuum cleaners are no exception, but only by relying on themselves to really use it to judge whether a product is good or not.

Secondly, the most special point is that the finger butler is a household vacuum cleaner that can kill viruses, which can kill H1N1 virus, hand, foot and mouth virus and other viruses and harmful bacteria within 1 minute.

What brand of vacuum cleaner is better, according to me, the finger butler household vacuum cleaner is very good.

KV series single industrial vacuum cleaner is a kind of environmentally friendly cleaning equipment commonly used in the industrial production process, this vacuum cleaner is easy to use and move, good cleaning effect, generally used in cement, furniture, ceramics, chemical industry, construction, hardware, plastics, powder operations, cutting operations, grinding operations, sandblasting operations and other customer site single-phase electricity working conditions, used to collect waste in the industrial production process, filter and purify the air, environmental cleaning, can prevent some occupational disease hazards and improve production efficiency.

Your question is a bit big, so let's talk about it briefly.

One is to deal with sawdust dust, it is best to use a bag dust collector, there are three kinds of rapping and pulse injection and dust capture, the effect is good, if the dust removal rate is not high, you can also use a cyclone separator, the dust removal rate is more than 85%.

The other is to remove the paint mist, which is a little more complicated, because he not only has to remove the paint mist dust, but also the smell, otherwise the Environmental Protection Bureau will not agree. This system is composed of two parts, one is the dust collector body, which must be pulse bag-type, the filter bag requires special materials, and it is not easy to be stuck by paint mist, and the other is the suction tower, which is specially designed to remove odors, and after two-step treatment, clean air can be discharged at will. There is also an infrared heating technology for removing odors, I think the technology is not too mature, I dare not talk nonsense, you can check it yourself, it is best to visit the field.

The problem of power consumption mainly depends on your air volume or processing capacity, and the large air volume will naturally increase the power. There is a key problem here, that is, the design and production of the pipeline must be scientific and reasonable, minimize the resistance, and reduce the pressure head of the fan, so as to reduce the useless work of the fan and play an energy-saving role.

It is an ordinary fan, which is generally a single-phase motor or a three-phase motor.

Hope it helps.

Based on many years of experience in selection and production.

Jiuzheng Tongming believes that it is necessary for woodworking furniture factories to use woodworking dust collectors: sawdust and shavings are the dust generated by furniture factories, and the proportion of such dust is relatively light, which is very harmful to health and well-being. Appearance, these dust does not hurt people, but wood dust contains harmless substances composed of various phenols and hydrocarbons, and contains very strong carcinogenic substances, the most indirect damage is that the dust particles are particularly small, light, can be indirectly inhaled into the lung tissue, these dust particles are not digested or absorbed by the human body itself, it is very easy to damage the mucous membrane of the lungs, in the front line of wooden furniture consumption workers over time, the vast majority of people will suffer from lung diseases such as bronchitis, asthma and emphysema, and even cancer.

There are many types of dust collectors, and the selection is mainly determined by the nature of the dust and the required air volume.

The dust collector is the equipment that separates the dust from the flue gas, if it is used in industry, the electric bag composite dust collector is better.

There are several types of industrial dust collection equipment:

1. Electrostatic precipitator.

At present, the common types of electrostatic precipitator equipment in China can be roughly divided into the following categories: vertical and horizontal according to the direction of air flow, plate type and tube type according to the precipitation pole type, dry wet type, rotary umbrella type high-efficiency electrostatic precipitator and special high-voltage electrostatic precipitator according to the dust removal method on the precipitation plate.

Uses: Separating particulate dust and fine dust in industrial exhaust gas, widely used in metallurgy, mining, cement, thermal power plants, building materials, foundry, chemical industry, tobacco, asphalt mixer, grain, mechanical processing, boiler dust removal, cement raw meal, clinker mill, cupola furnace and so on.

2. Bag dust collector.

Most of the types of bag filters are named according to the way of ash cleaning, which are mainly divided into three types: mechanical vibration bag filter, atmospheric back-blowing bag filter and pulse jet bag filter, which have a high grading dust removal efficiency for fine dust with sub-micron particle size, and a wide range of gas volume.

Uses: Separation of particulate dust and fine dust in industrial waste gas, widely used in metallurgy, mining, cement, thermal power plants, building materials, foundry, chemical industry, tobacco, asphalt mixer, grain, mechanical processing, boiler dust removal.

3. Cyclone dust collector.

Cyclone dust removal equipment is a device that uses the principle of centrifugal force generated by accelerating the rotation of gas, and separating the rotating solid dust from the gas.

Uses: It is suitable for coarse and intermediate purification of dust in various industrial boilers, machining, metallurgical building materials, casting, mining, cement, and mining.

4. Wet dust collector.

The types of wet dust collectors have different classifications from different perspectives: according to the structural type, they can be divided into water storage wet dust collectors, pressurized water spray types and forced rotary spray wet desulfurization dust collectors; According to the energy consumption, it can be divided into low energy consumption and high energy consumption; According to the gas-liquid contact type, it can be divided into integral and dispersed contact wet dust collectors. Usage:

It is suitable for metallurgy, coal, chemical industry, casting, power generation, building materials and refractory industries.

5. Desulfurization dust collector.

The desulfurization dust collector mainly passes the flue gas through the stainless steel bulk packing, which increases the contact surface between the flue gas and the aqueous solution, and accelerates the full dissolution and neutralization of the flue gas and the spray water. You can choose according to your needs.

There are many types of industrial dust removal equipment, including the following:

1. The bag dust collector is composed of a bag, a shell, an ash hopper, an ash discharge device, a bracket, and a pulse ash cleaning system.

Working principle: When the dusty gas enters the dust collector from the air inlet, it first touches the oblique partition in the middle of the air inlet, and the air flow turns to flow into the ash hopper, and the air flow speed slows down at the same time, due to the inertia, the coarse particles of dust in the gas fall directly into the ash hopper, which plays the role of pre-dust collection. The air flow into the ash hopper then folds upwards through the filter bag equipped with a metal skeleton inside, and the purified gas collected by dust ** on the outer surface of the filter bag enters the clean room at the upper part of the filter bag chamber and is collected and discharged into the air outlet pipe.

2. The cyclone dust collector is composed of a cylinder, a cone, an inner cylinder, an air inlet pipe, an exhaust pipe, etc.

How it works: The dust-laden gas is introduced from the inlet between the housing and the exhaust pipe of the dust collector, forming an external swirl that rotates downward. The dust suspended in the external swirl flow moves to the wall of the device under the action of centrifugal force, and flows to the lower part of the dust collector with the external swirl flow, and is discharged through the dust exhaust hole.

The purified gas forms a rising internal swirl and is discharged through the exhaust pipe.

3. The electrostatic precipitator is composed of an inlet smoke box, an anode and anode plate, a flow sharing plate, a clean air chamber, a cloth bag, an ash hopper, etc.

Working principle: When the flue gas passes through the flue in front of the main structure of the electrostatic precipitator, the smoke and dust are positively charged, and then the flue gas enters the electrostatic precipitator channel with multi-layer cathode plates. Due to the mutual adsorption of the positively charged smoke and the cathode electric plate, the particle smoke in the flue gas is adsorbed on the cathode, and the cathode plate is hit regularly, so that the smoke and dust with a certain thickness fall in the ash hopper under the structure of the electrostatic precipitator under the dual action of self-weight and vibration, so as to achieve the purpose of removing the smoke and dust in the flue gas.

4. The conventional structure of the spray tower is summarized as follows: one layer of defogging, two layers of spraying, three layers of packing, four windows, and five live ball valves.

Working principle: In the spray tower, the dusty gas moves upward, and the liquid moves downward by the nozzle. Due to the inertial collision, interception and condensation between the liquid and the particles, the larger particles are trapped by the liquid.

There are many types of industrial dust collectors, how to choose, you should start from the following points:

1.First of all, look at the operating temperature. Normal temperature or high temperature.

2.The nature of the dust, whether it is abrasive, the size of the particles, whether it contains moisture, whether it is sticky.

3.Operational stability, whether there are shutdown conditions. If it is continuous operation, you should choose a dust collector that runs non-stop.

In fact, it is not recommended that users choose industrial dust collectors by themselves, and they can find some experienced engineers to choose. Engineers will make reasonable choices based on empirical data.

It depends on the specific requirements, depending on the number of dust-producing equipment (disc saws, belt sanding machines), the number of equipment manufacturers wearing, the workshop wears some taste-like equipment, and the equipment is placed in the monotube room, and the equipment is less and the equipment is too flavorful.

The woodworking dust collector needs to determine the air volume before it can be selected, and the dust collection hood size of the woodworking dust collector is designed according to the size of the relevant equipment in its own woodworking workshop, and the air volume is determined according to the area of the dust collection hood and then the woodworking dust collector model is determined.

Key points of woodworking dust collector selection:

1. Selection of filter wind speed of dust collector: In the selection and design of woodworking dust collector, the filter wind speed is very important, which should be determined according to the nature of smoke or dust, use occasions, dust particle size, viscosity, gas temperature, moisture content, dust concentration and different filter materials. When the dust particle size is fine, the temperature and humidity are high, the concentration is large, and the viscosity is large, the filter wind speed should be selected at a low value.

2. Selection of air volume, gas temperature, dust concentration and humidity of the dust removal system: according to the value of air volume, gas temperature and dust concentration planned by the skill, the value is slightly smaller than the value in the skill performance table, and the corresponding dust collector type is the type of dust collector required.

3. Selection of dust removal bags: It is necessary to think about the selection of key cloth bags according to the temperature of the dust-containing gas, the moisture content, the acid, the alkali properties, the viscosity of the dust, the concentration and the abrasive pecking. Usually when the water content is small and non-acidic, it is selected according to the temperature of the dusty gas, and at room temperature or 130 °C, 500-550g m2 polyester needle felt is commonly used.
