INTRODUCE

DMC pulse bag dust collector is a new type of high-efficiency pulse dust collector that is improved on the basis of bag dust collector. The pulse bag filter has been further improved, and the modified pulse bag filter retains high purification efficiency, large gas processing capacity, stable performance, and convenient operation.

CHARACTERISTIC

1. Large air volume per unit volume,high dust removal efficiency.

2. The dust collector can directly process the dust-containing gas with dust concentration up to 1000g/Nm3,and the emission concentration of the treated gas is lower than 50mg/Nm3. It can also meet more stringent emission standards according to special requirements of users.

3. Different types of flue gas can be treated with different filter materials to meet the emission requirements and have strong adaptability.

4. The dust collector adopts advanced pulse valve with reliable performance. The service life of pulse valve is 1000000 times.

5. The dust remover adopts the advanced PLC programmable controller, which automatically sprays and blows ash at fixed time or constant resistance,and realizes automatic operation,with small air consumption,thorough ash removal and stable performance.

APPLICATION SCOPE

The company provides a complete set of flue gas purification and treatment schemes for steel,cement,nonferrous metal smelting, coal coking,chemical industry,building materials and other fields, achieving the ideal dust removal effect. The company has different bag-type dust collector of different specifications, and can provide customized services according to your requirements and industry characteristics.

WORKING PRINCIPLE

Under the attraction of the induced draft fan,the dust-containing gas enters the ash hopper and is evenly distributed to each filter bag after passing through the deflector. Dust is intercepted on the external surface of the filter bag,and gas passes through the filter bag and is discharged outside after passing through the clean air chamber.The dust collected on the external surface of the filter bag by the bag-type dust collector will reduce the air permeability of the filter bag and increase the resistance of the dust collector continuously until the resistance reaches the set value (differential pressure control) or the filtration time reaches the set value(time control). Generally, the pulse valve in the closed state is opened for a very short period of time (about0.1s) under the pulse blowing control of PLC pulse blowing controller, and the high pressure gas enters the blowing pipe from the air bag instantaneously, And ejected from the blowing hole at high speed. The high velocity air flow injected into the filter bag generates a secondary flow several times more than the injected gas. The combined action of jet air flow and secondary drainage rapidly increases the pressure on the inner side of the filter bag,the filter bag changes from the original concave shape to the convex shape, and generates a large reverse acceleration when the deformation reaches the maximum value. The dust adsorbed on the filter bag is mainly separated from the surface of the filter bag and falls into the ash hopper under the effect of the reverse acceleration, and the resistance of the dust collector decreases accordingly. The process of removing dust from the filter bag surface is called dust removal. Ash removal is carried out one by one. Every time the pulse valve acts, one row of filter bags will be cleaned. The pulse valve operates successively according to the set time interval and sequence until a cycle is completed. The whole dust collector has completed one ash removal cycle.
