What is the standard for dust removal skeleton? Zhuzhou Chenxiang Environmental Protection will answer for you:

1.The dust removal skeleton requires that the support rings and longitudinal bars are evenly distributed, and should have sufficient strength and rigidity;

2.All welding of the dust removal skeleton must be of high standard and high precision, and the solder joints should be welded firmly, and no desoldering is allowed. virtual soldering and missing soldering;

3.The surface of the dust removal skeleton in contact with the dust removal must be smooth and clean, and no welding scars are allowed. bumps and burrs;

4.The tension spring skeleton should have enough turns and elasticity, and the spacing should be uniform after opening;

5.The surface treatment of the dust removal skeleton according to different needs must meet the technical standards to meet the requirements of temperature resistance and corrosion resistance.

6.The size of the dust removal skeleton must be accurate, with a verticality of 6m plus or minus 1mm.

7.The design of the dust removal skeleton must be reasonable and practical, and there are two or three sections as a whole and in sections according to the current requirements.

8.The length of the dust removal skeleton is more than 3 meters, and the steel one-time forming tube is worn.

9.The production of the dust removal skeleton is fully automated to prevent damage to the product during the production process.

10.The dust removal skeleton tracks the whole process from raw material processing to on-site installation to ensure the quality of each link.

The skeleton is the support of the dust removal filter bag, and the skeleton of different materials and different post-processing processes can change the industrial and mining conditions of the skeleton. The ordinary galvanized and plastic-sprayed skeleton can be used for a long time in a non-corrosive 130 working environment, and its life span can be up to 3 years. However, it is not suitable to use this kind of skeleton in a high-temperature, corrosive environment.

The skeleton of the skeleton can be obtained mainly from changing the material of the skeleton and the post-processing method, and at first it can be obtained by changing the material of the skeleton, that is, the stainless steel wire is selected instead of the low-carbon steel wire to make the skeleton, and the unique characteristics of stainless steel cope with this working condition very well; The skeleton can also be obtained by changing the post-processing method of the skeleton, that is, the silicon treatment method replaces the galvanized or sprayed treatment method, and the silicon treated skeleton can cope with high temperatures and corrosive conditions within 300 meters.

The calculation of the dust removal skeleton should be calculated according to the specific parameters The general transportation cost is relatively high, and the freight is calculated according to the party, so it is necessary to pay more attention to the calculation of freight.

For example, when purchasing 130 times 6 meters of cloth bags supporting the number of skeletons of 3000, the size of the general skeleton is 115 times 5980, and the calculation method is that the calculation result is square, and the general loading may occupy slightly more space than the actual calculation due to the problem of placement, so the approximate number is 240 square meters, so that you can know the total freight at the price of each square, and then divide by the quantity.

Dust removal skeleton.

The selection of materials and treatment methods for the dust collector skeleton is very important, because the dust removal skeleton is the core component of the bag filter, and it is very important whether the selected dust removal skeleton can adapt to the flue gas temperature. Therefore, we must first understand what is the operating temperature of the dust removal skeleton, and only the use temperature of the dust removal skeleton can correctly select the appropriate dust collector skeleton.

According to the use temperature, the dust removal skeleton is divided into: room temperature dust removal skeleton 130 or less, medium temperature dust removal skeleton between 130 and 180, high temperature dust removal skeleton between 180 and 280, knowing the flue gas temperature and the use temperature of the dust removal skeleton, in the selection of the appropriate dust removal skeleton later dust removal method, you can extend the use time of the equipment very well, the general dust removal skeleton surface treatment is divided into: surface galvanizing, silicone powder electrostatic spraying, spraying three kinds.

The following is an introduction to the classification and use of the post-processing method of the dust removal skeleton.

Silicone dust removal skeleton.

The silicone dust removal skeleton has good high temperature resistance and corrosion resistance, and the silicone dust removal skeleton can be used in the industrial and mining environment of about 280 meters, and the instantaneous use temperature can reach 300 meters. In some specific environments, it can replace the stainless steel dust removal skeleton to reduce the manufacturing cost of the enterprise, and the post-welding treatment of the silicone dust removal skeleton is galvanized on the surface to prevent rust, and the silicone dust removal skeleton is widely used in high temperature and high corrosion environments;

Spray dust removal skeleton.

The spray dust removal skeleton is mainly used in the working conditions of room temperature 130 -160 range, and the spray dust removal skeleton can do not damage the filter bag, erosion resistance, wear resistance, high temperature resistance and anti-static resistance;

Galvanized dust removal skeleton.

The galvanized dust removal skeleton adopts cold drawing wire and then galvanized after special welding equipment, the rust resistance of the skeleton can be increased after galvanizing treatment, and the damage to the filter bag can be reduced when changing the dust removal bag, the galvanized dust removal skeleton can generally be used in the industrial and mining environment of about 280, and the instantaneous use temperature can reach 300, due to the cheaper price, in many working conditions, the most selected is the galvanized skeleton;

Stainless steel dust removal skeleton.

Stainless steel dust removal skeleton material and other grades of materials, mostly used in corrosive or acid-alkali concentration is generally not very high working conditions, due to its relatively high cost, so many customers will only choose stainless steel skeleton under special circumstances.

If the working effect of the dust removal skeleton is relatively poor, the following aspects can be referred to to analyze and solve this problem:

1. The influence of the size of the dust removal skeleton: in the geometric size of the dust removal skeleton, the diameter of the dust removal skeleton, the gas and the shape and size of the exhaust pipe are important influencing factors.

2. The influence of gas parameters on the performance of the dust removal skeleton: including the influence of gas flow, the influence of gas dust concentration, the influence of gas moisture content, the influence of gas density, viscosity, pressure, temperature, etc.

3. Influence of the roughness of the inner wall of the dust removal skeleton: the dust particles concentrated near the wall will cause swirl due to the rough surface, so that some dust particles are thrown into the rising air flow and enter the exhaust pipe, which reduces the dust removal efficiency.

4. The influence of airflow distribution on the bag skeleton joint: there is no direct relationship between dust removal efficiency and airflow distribution, that is, airflow distribution does not affect dust removal efficiency. However, the local airflow distribution inside the skeleton joint should be as uniform as possible, and the deviation should not be too large, otherwise the bag will be broken due to local uneven load or jet wear, which will affect the normal service life of the skeleton joint filter bag.

Dust removal skeleton.

The cage dust removal skeleton needs to be evenly distributed with support rings and longitudinal bars, and has sufficient strength and rigidity, can withstand the gas pressure of the dust removal bag in the filtration and ash cleaning situation, and can prevent the damage and deformation caused by bumps and impacts in the normal transportation and equipment process.

Required process: firm welding, smooth and straight appearance. The dust removal skeleton is the rib of the filter bag, and the quality of the dust removal skeleton directly affects the working state and service life of the filter bag.

Skeleton type: Commonly used are circular skeleton, trapezoidal skeleton and spring skeleton, and dust removal equipment manufacturers produce skeletons.

The dust removal frame, also known as the dust bag cage, is the "rib" of the filter bag, which is welded and formed by special equipment at one time, made of iron wire or stainless steel wire, and disposed of after the appearance by galvanizing, spraying, silicone and other methods.

Bag round bag type dust removal frame (external filter type) The dust removal frame, also known as the dust removal skeleton, is welded and formed by special equipment at one time, and its characteristics: strong welding, bright and straight surface. The dust removal frame is the rib of the dust removal cloth bag, which is the main accessory of the dust collector.

The dust removal skeleton is the rib of the filter bag, it should be light, easy to install and maintain, and the quality of the frame directly affects the filtration status and service life of the filter bag. Dust removal skeleton is widely used in metallurgy, building materials, power generation, chemical industry, food, waste incinerator and other industries.

The dust removal skeleton adopts galvanizing technology, and the coating is firm, wear-resistant and corrosion-resistant, which avoids the rust on the surface of the skeleton and the adhesion of the filter bag after the dust collector works for a period of time, ensures the smooth bag change, and reduces the damage to the bag during the bag change. Characteristics of the skeleton of the dust collector The flow pattern design of the shell cyclone dust collector can play a local cyclone role and reduce the load of the filter bag. The shape of the cylindrical vault is uniform and has good anti-explosion performance.

It is not limited by the air source conditions of the use occasions, with few wearing parts, easy maintenance and reliable operation. Overcoming the cheating of compressed air pulse cleaning. The back-blowing has a large acting distance, and a long filter bag can be used to make full use of the space and occupy a small area.

The trapezoidal flat bag is arranged in the cylinder, which is simple and compact in structure, and improves the service life of the filter bag. The doors and openings are pre-sealed, and the heat emitted in the control cabinet exceeds the allowable temperature of the components, and the cabinet is mechanical. After the dust-containing gas of the dust collector skeleton enters the ash hopper of the dust collector, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, a part of the coarse particles in the airflow settle in the ash hopper under the action of dynamic and inertial forces.

The filter bag is very critical to the bag filter, and the dust removal skeleton as the rib of the filter bag has the advantages of being lightweight, easy to install and maintain. They all have different characteristics in terms of technical requirements and scope of application.
