Tianjin Caigang Plant welding fume collection device filter cartridge dust collector film polyester filter cartridge good quality

With the environmental protection department's strict investigation of environmental pollution, many enterprises require the installation of environmentally-friendly dust-removing devices. Tianjin Yicai Steel Plant has more than 20 electric welding operation points. The use of small-sized mobile welding fume purifiers is not effective and the cost is high. A filter cartridge type pulse dust collector was recommended for the personnel.

Pulse filter cartridge dust collector is a small and efficient dust collector that combines the advantages of pulse dust collector and filter cartridge dust collector. The product equipment has the advantages of high dust removal efficiency, good filtering effect and stable operation of the pulse dust collector, and also has the two-way superior performance of the filter cartridge dust collector with good sealing performance and long service life.

The difference between filter bag and filter cartridge when dealing with welding fumes:

Advantages of the filter bag:

1. The service life of the filter bag is relatively long, and it is not easy to break and the powder leakage occurs;

2. The filter bag has better cleaning effect and more thorough cleaning;

3. Subsequent long-term operation and maintenance costs are lower;

4. High filtration efficiency and wide application range.

The disadvantages of the filter bag:

1. The filter area of ​​a single filter bag is small;

2. Because the filter area of ​​a single filter bag is small, the bag filter device is slightly larger, so the floor space is slightly larger. Compared with the filter cartridge type filter, the size of the filter bag will be slightly larger. ;

3. Due to the large size of the equipment, the initial input cost is slightly larger.

Advantages of the filter cartridge:

1. The initial input cost is small;

2. The equipment is small in size and small in floor space;

3. The filtering effect and the filtering effect of the bag are basically the same as the selection of materials, and they are all widely used in the market.

The disadvantages of the filter cartridge:

1. Since the surface of the filter cartridge is V-shaped wrinkles, the compressed air is easily damaged by the compressed air when it is repeatedly cleaned;

2. Because the V-shaped wrinkle space is small, the dust is likely to remain or accumulate in the V-shape, and it is difficult to clean the dust. Even the filter cartridge is clogged, and the filtration resistance is increased, so that the filtration area is reduced, so that the filter cartridge is more likely to be damaged;

3. Because the filter cartridge is easy to block and break, the frequency of replacement is relatively high;

4. Only for smaller particle dusts and not for explosion-proof dust. For the inflammable and explosive dust, only the filter bag type dust collector can be used. The reason why the Zui is large is that the surface of the filter bag is relatively smooth, and it is installed vertically, so the cleaning effect is good, and it is difficult to accumulate dust. For flammable and explosive dust, the form of the dust collector is clearly defined in the “Safety Technical Specifications for Dust Removal Systems in Dust Explosion Hazardous Locations”.

Our company's new technology improvements for filter cartridges:

1 cleaning device

The conventional filter cartridge dust collector has two kinds of cleaning methods, one is high-pressure airflow back-blowing, and the other is pulsed airflow blowing. The practice shows that the former has the advantages of uniform airflow, and the disadvantage is that the air consumption is large; the latter has the advantage of consumption. The gas volume is small, and the disadvantage is that the airflow is weak. To this end, two improvements can be made: on the one hand, a flow guiding device is added to the pulse blowing pipe to enhance the airflow inducing effect, and on the other hand, the upper guiding air duct of the filter cartridge is cancelled, so that the pulsed airflow and the induced airflow simultaneously enter the filter cartridge at the same time. . In this way, the air consumption is small, the airflow is uniform, and the cleaning effect is good. According to the calculation, the flow rate of the cleaned airflow after the technical improvement is 3-5 times of the pulse gas volume.

2 gas distribution plate

The airflow distribution of the filter cartridge is important, and it must be considered how to avoid high wear areas of the filter material due to the high wind speed at the inlet of the equipment. The air distribution plate has unique requirements for the filter cartridge dust collector, and the airflow distribution must be very stable and uniform. It is beneficial to the rise of airflow and the drop of dust, and the opening ratio of the airflow distribution plate is 35%. According to the calculation, the drag coefficient is <2, which shows that the porous airflow distribution plate can meet the requirements of the filter cartridge type dust collector when the airflow velocity is <0.8 m/s.
