Industrial Welding Fume Extractor

The pulse filter dust collector is an improved filter type pulse dust collector based on the bag filter. The purification efficiency is relatively high, the gas processing capacity is large, the performance is stable, the filter bag life is long, the operation is convenient, and the maintenance workload is small. Widely used in electronics factory, circuit board, acrylic, grinding and polishing, vacuum feeding, rubber cutting, metal welding, food machinery, foundry machinery, laser plasma and other industries. \\The pulse dust collector is a new type of pulse dust collector improved on the basis of the bag filter. It combines the advantages of various pulse jet dust collectors with sub-chamber backflushing, and overcomes the shortcomings of insufficient cleaning intensity of the sub-chambers and uneven distribution of air in and out. , expanding the scope of application.

The pulse dust collector is that when the dust-laden gas enters the dust collector from the air inlet, it first encounters the inclined plate and baffle plate in the middle of the air inlet and outlet, and the air flow turns to flow into the ash hopper. At the same time, the air flow speed slows down. Dust flows directly into the ash hopper. It plays the role of pre-dust collection. The airflow entering the ash hopper is then folded upward and passed through the filter element with a metal skeleton inside. , In the process of dust-laden gas passing through the filter element, more and more dust is accumulated on the filter element with the increase of time, which increases the resistance of the filter element, resulting in the gradual reduction of the treated air volume. In order to work normally, the resistance should be controlled within a certain range. , once it exceeds the range, the filter element must be cleaned. When cleaning the dust, the pulse controller will trigger each control valve to open the pulse valve in sequence, and the compressed air in the cylinder will be sprayed into the corresponding filter element from each hole of the injection pipe, and the filter element will be sharp in an instant. The expansion causes the dust accumulated on the surface of the filter element to fall off, and the filter element returns to its original state. Clear the dust into the ash hopper and collect it into the extraction cabinet for concentration. As a result, the dust accumulated on the filter element is periodically pulsed to clean the dust, so that the purified gas can pass normally and ensure the operation of the dust removal system.

Features

1. Adopting sub-chamber air-stop pulse jet cleaning technology, which overcomes the shortcomings of conventional pulse dust collectors and sub-chamber back-flushing dust collectors, with strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, steel Less consumption, less floor space, stable and reliable operation, and good economic benefits. It is suitable for the purification of dusty gas and the recovery of materials in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

2. Due to the use of sub-chamber air stop pulse jet to clean the dust, the purpose of complete dust removal can be achieved by one injection, so the dust removal cycle is prolonged, the energy consumption of dust removal is reduced, and the consumption of compressed air can be greatly reduced. At the same time, the fatigue degree of the filter bag and the pulse valve is also reduced accordingly, thereby improving the life of the filter bag and the valve plate.

3. The maintenance and replacement of bags can be carried out in separate rooms under the normal operating conditions of the system without stopping the system fan. The mouth of the filter bag adopts an elastic expansion ring, which has good sealing performance and is firm and reliable. The filter bag keel adopts polygonal shape, which reduces the friction between the bag and the keel, prolongs the life of the bag, and facilitates the unloading of the bag.

4. The upper part of the bag is drawn. After the skeleton is pulled out when changing the bag, the dirty bag is put into the ash hopper at the lower part of the box and taken out from the manhole, which improves the operating conditions of changing the bag.

5. The box body is designed with air tightness, which has good sealing performance. The inspection door is made of excellent sealing material. Leakage is detected during the production process, and the air leakage rate is low.

6. The inlet and outlet air ducts are compactly arranged, and the airflow resistance is small
