The pulse bag filter on the top of the warehouse absorbs the advantages of the original pulse bag filter, changes the original ash discharge system, simplifies the structure, and has the characteristics of high gas processing capacity, good purification effect, and reliable operation. Compared with the mechanical vibration type top bag filter, this top pulse bag filter also has the characteristics of low working noise and long service life of filter bags. It is suitable for capturing various small and dry non fibrous dust and is a simple storage dust removal equipment.

This type of dust collector is generally used on the top of cement tanks in mixing plants, coal yards, and ventilation type dust collectors on various warehouse roofs. It usually does not have an ash hopper and is directly connected to the top of the warehouse with a flange. When adding materials to the tank, the dust collector is a ventilation hole. After filtering and meeting emission standards, the collected dust falls directly into the tank or cylinder. Most of the pulse dust collectors on the top of the warehouse are high-efficiency and purification specific dust removal equipment designed specifically for the working conditions of ash storage, slag storage, ash tanks, and coal tanks in foundries and thermal power plants.

Working principle of pulse bag filter on the top of the warehouse

When the top pulse bag filter is working, dusty air enters the dust removal box of the top pulse bag filter from the bottom of the top pulse bag filter. Coarse particles of dust settle down by the gravity of the top pulse bag filter and fall into the ash bin. Fine dust is adsorbed on the dust bag through various effects. As time goes by, it accumulates thicker and the resistance of the top pulse bag filter gradually increases, and the amount of gas processed decreases. In order to maintain the effective working state of the top pulse bag filter and keep the pressure loss within a certain range, it is necessary to adsorb the accumulated dust outside the bag wall.

The dust removal process of the bin top bag filter is that the controller sends instructions to each electromagnetic pulse valve according to the specified requirements, so that the filter bag can rapidly shrink, expand and shrink in a moment. During the dust removal process, the pressure loss of the bin top bag filter and the amount of dust containing gas being treated are almost unchanged, which is one of the progressiveness of the bin top pulse bag filter.

Advantages of pulse bag filter on the top of the warehouse

1. The filter material used meets emission standards and has a long lifespan

The warehouse top pulse dust collector produced by Huakang uses a filtering unit filter bag and bag cage. The filter bag is made of polyester needle punched felt material, and our manufacturer can determine the corresponding filter material bag according to the material used by the customer. Therefore, it is well applied to customers in application. The bag and frame both adopt a circular design, which effectively avoids the possibility of dust accumulation on the surface of the bag.

2. The dust cleaning method adopts pulse blowing and intelligent control, ensuring the stable operation of the equipment

It uses compressed air as the gas source for the top dust collector, and achieves automatic pulse valve blowing through an intelligent controller. The pulse online blowback ability is large, and the dust cleaning is relatively good. The top dust collector completes the cleaning in operation, and the periodic cleaning time interval can be automatically controlled, thus ensuring the long-term stable operation of the top dust collector.

3. The active induced draft system is adopted to reduce the impact of the silo on the high pressure of the top dust collector. Huakang's top bag dust collector is equipped with an active induced draft fan, which can effectively reduce the pressure inside the silo, ensure smooth feeding operation, and stabilize the operation of the top dust collector.

Technical parameters of pulse bag filter on the top of the warehouse

Case study of pulse bag dust collector on the top of the warehouse

Customer situation: Tianjin concrete mixing plant has ordered 5 sets of top pulse bag dust collectors from our company, with a dust removal rate of up to 99% and easy installation.

Usage effect: It can collect the dust generated during the feeding process of the concrete mixing plant silo and directly fall into the silo. The treatment effect is very obvious and has been recognized by users.
