What method is used to deal with smog for air purification in industrial plants

The air purifier is usually composed of a circuit ionizer, a micro-fan, an air filter and other systems, and its working principle is as follows: the micro-fan (also known as the ventilator) in the machine circulates the indoor air, and the polluted air removes or adsorbs various pollutants after passing through the air filter in the machine (filtered twice), and then passes through the negative ion generator installed in the air outlet (the high voltage in the negative ion generator produces DC negative high voltage during work), and the air is continuously ionized to produce a large number of negative ions, which are sent out by the micro fan. The formation of negative ion airflow to achieve the purpose of cleaning and purifying the air, so as to provide people with a "microclimate environment" similar to the fresh air in nature.

As early as the 5th and 6th decades of the last century, due to the needs of industrial production technology, foreign countries have begun to build clean rooms, and more and more air clean rooms have been built in China since the 80s!

The main industries that need to build clean rooms are the electronics industry, the pharmaceutical industry, precision machining, etc.!

Industrial clean rooms generally detect particles of microns, or even smaller microns, and the requirements are much higher than those of today's household haze treatment!

Generally, coarse, medium, and high-efficiency filtration above level 3 is required, and the fresh air introduced also has relatively strict proportions and filtration requirements!

It is recommended to use a fresh air purification system, this is to have a purification host, and then use the pipe for air flow, the fresh air purifier is mainly to purify the outdoor air to flow indoors, purify the air and add a lot of fresh oxygen to the indoor air, our factory is using this kind, I hope it will help you

The purification workshop is also called dust-free workshop, clean punching workshop, and clean room, which refers to the elimination of fine particles in the air within a certain space range, harmful air, bacteria, etc., and the indoor temperature, cleanliness, indoor pressure, air velocity and air flow distribution, noise, vibration, lighting, and static electricity are controlled within a certain range of needs, and the specially designed space is given. Have a great day, dear ones. I hope mine helps you

Hello, the purification workshop is a place with high air quality requirements, so the compressed air used in the purification workshop also needs to meet certain requirements. The following are the common compressed air requirements for clean rooms:1

Cleanliness: The compressed air in the purification workshop must be kept clean and oil-free enough to avoid airborne particles and oil stains affecting the quality of the product. For this reason, it is necessary to install filters, oil-water separators and other equipment in the compressed air system to purify the air.

2.Dryness: The compressed air in the purification workshop also needs to maintain sufficient dryness to avoid the impact of water on the product.

Therefore, it is necessary to install equipment such as dryers or coolers in compressed air systems to reduce the humidity in the air. 3.Pressure Stability:

The production of the purification workshop needs to maintain a certain pressure stability, therefore, it is necessary to install pressure regulators and other equipment in the compressed air system to ensure the stability of the pressure. 4.Pressure**:

The compressed air in the clean room also needs to be pressured**, as this can affect production efficiency and product quality. Therefore, it is necessary to install shock absorbers, shock absorbers and other equipment in the compressed air system to reduce the pressure**. In short, the compressed air requirements of the purification workshop are relatively high, and it is necessary to maintain sufficient cleanliness, dryness, pressure stability and avoid pressure**.

Hello, how big is your plant. How many dust spots. What kind of dust, if the amount of dust is small, you can use small treatment equipment.

If the plant is large, there are more dust spots. A bag dust collector can be used. This is the best way to deal with dust today.

It is also the most effective equipment to improve the working environment.

How the dust collector works.

The clean workshop refers to the reduction of dust, bacteria, viruses, etc. in a certain space, and the realization of constant temperature and humidity, the reduction of noise, etc., to provide a good production environment for the production of products. So what are the purification methods suitable for clean workshops?

Electrostatic purification method.

The electrostatic purification method is to use the principle of high-voltage electrostatic adsorption to achieve the effect of dust removal. The cathode line in the electrostatic field produces a large number of negative ions under the action of high-voltage static electricity, and the negative ions continue to move to the anode under the action of the electrostatic field. When the dust in the air passes through the electric field, the dust will be charged when it receives the impact of negative ions, and the dust charge with static electricity will also be affected by the electrostatic field, and the movement to the anode is to release the charge after reaching the anode.

Physical decontamination methods.

1.Adsorption filtration is activated carbon. Activated carbon is a porous carbon-containing material with a highly developed pore structure, and the porous structure of activated carbon provides it with a large amount of surface area and can be in complete contact with gases (impurities), which makes activated carbon have adsorption properties and easily achieve the purpose of absorbing and collecting impurities.

Like magnetism, all the molecules have a mutual attraction to each other.

2.Mechanical filtration: HEPA net, Chinese means high-efficiency air filter, up to HEPA standard filter, for microns the effective rate of reach, HEPA mesh is characterized by air through, but small particles can not pass.

The HEPA filter consists of a stack of sub-glass fiber membranes that are continuously folded back and forth to form a corrugated gasket that is used to place and support the filter boundary.

Liquid absorption purification principle: the process of treating a mixture of gases with a liquid absorbent to remove one or several of them.

In this process, the physical action of dissolving certain gases in solution occurs, which is physical absorption; There are also chemical reactions that occur between chemicals in gases and liquids, which is chemical absorption.

Liquid absorption-activated carbon adsorption principle: according to the solubility of styrene exhaust gas in water is very small, but it has the characteristics of good solubility in some petroleum substances, and meets the concentration of waste gas purification does not exceed the sanitary standard of the workshop, the two-stage purification working principle is adopted. The first stage uses high-efficiency liquid absorption, and the second stage uses activated carbon adsorption.

Other purification methods.

1.Negative ion method.

After hydroxyl anion comes into contact with harmful gases floating in the air, it can restore the reactive oxygen species (oxygen radicals) generated by pollutants, nitrogen oxides, cigarettes, etc. from the atmosphere, and reduce the harm of excessive reactive oxygen species to the human body; Neutralizes the positively charged air dust and settles after no charge, so that the air is purified.

2.Washing method.

Using the principle of siphon and centrifugation, the purifier mixed in water is sucked into the straw of the lower part of the coaxial centrifugal turbine of the motor base through the siphon principle, and rotates at high speed through the AC shaded pole motor, and then the centrifugal principle is used to spray the purifier mixed in the water to form a layer of water film in the bottle bile, inhale the dust and bacteria in the air into the water, and blow the purified air into the room at the same time, quickly and effectively remove the toxin organisms, dust, smoke, odor, virus, etc. in the room, and produce a large amount of fresh oxygen.
