Large pulse bag filter

The large pulse bag dust collector is a new type of pulse bag dust collector developed by Huakang Zhongtian Engineering technicians with the help of advanced domestic dust removal technology. Widely applicable for flue gas treatment in industries such as power, building materials, metallurgy, and chemical engineering, especially for high air volume and high temperature flue gas. It combines the characteristics of chamber back blowing and pulse cleaning, overcoming the shortcomings of insufficient intensity of ordinary chamber back blowing and general pulse cleaning dust re adsorption. Moreover, the extended filter bag fully utilizes the powerful cleaning effect of compressed air. It is a large-scale dust removal equipment with high dust removal efficiency, small footprint, stable operation, reliable performance, and easy maintenance.

Characteristics of Large Pulse Bag Dust Collector

1. Adopting pulse jet cleaning technology, it has strong cleaning ability, high dust removal efficiency, low emission concentration, small air leakage coefficient, low energy consumption, low steel consumption, small footprint, stable and reliable operation, and is economical

Good benefits. Suitable for flue gas treatment in industries such as power, building materials, metallurgy, and chemical engineering.

2. The box adopts an airtight design with good sealing performance. The inspection door is made of excellent sealing materials, and the manufacturing process uses kerosene for leak detection, resulting in a low air leakage rate.

3. Compact inlet and outlet air ducts and uniform devices have low airflow resistance.

4. By using a segmented pulse cleaning system, the cleaning cycle is long and the consumption is low, which can double the lifespan of the filter bag and pulse valve.

5. It can achieve non-stop bag replacement and maintenance without affecting the normal operation of the equipment.

6. The use of upper bag extraction method has improved the operation of bag replacement.

7. A comprehensive control system ensures the long-term operation of the dust removal system

Working principle of large pulse bag filter

The dusty gas enters the ash hopper through the air inlet duct, and the coarse dust particles directly fall into the bottom of the ash hopper. The fine dust particles enter the middle and lower boxes upward with the turning of the air flow, and the dust accumulates on the outer surface of the filter bag. The filtered gas enters the upper box and is discharged to the atmosphere through the exhaust fan via the clean gas collection pipe exhaust duct. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time to ensure that the dust peeled off from the filter bag settles in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The filter bag is cleaned, and the exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller.
