The BMD Pulse Filter Bag Dust Collector is a new type of bag dust collector, which is a type of flat bag dust collector with anti blowing air outside the chamber. The BMD bag filter consists of five parts: a clean air box, a dust air box, an ash hopper, a blowing device, and a bracket. The clean air box is equipped with a blowing pipe, and the clean air part has a clean air outlet. The front is a maintenance door, and when the maintenance door is opened, any filter bag can be easily replaced. The dust air part has a dust air inlet located at the upper part of the air box, and there are filter bags and ash hoppers inside the box. After the dust air enters the dust air box, the clean air passes through the filter bags and goes to the clean air box. The dust will settle into the ash hopper, and the settling direction is consistent with the airflow direction, which is conducive to the settling of dust. There is a partition between the clean air box and the dust air box, and the size of the filter bag is 1200mm long. A rectangular flat filter bag with a width of 480mm and a thickness of 26mm, equipped with a reverse blowing device, installed under the clean air box, including an air bag, pulse valve, pulse controller, etc.
The BMD type bag filter consists of five parts: a clean air box, a dust air box, an ash hopper, a blowing device, and a bracket.
1、 Clean air box section: This section is equipped with a spray pipe, with a clean air outlet at the top and a maintenance door at the front. When the maintenance door is opened, any filter bag can be easily replaced.
2、 Dust and gas section: The dust and gas inlet is located at the upper part of the gas box, which is equipped with filter bags.
3、 Ash hopper section: After the dust enters the dust box, clean air is filtered through a filter bag and sent to the clean air box. Dust will settle into the ash hopper. And the settling direction is consistent with the airflow direction, which is conducive to the settling of dust. There is a partition between the clean air box and the dust air box, and the filter bag size is a rectangular flat filter bag with a length of 1200mm, a width of 480mm, and a thickness of 26mm.
4、 Anti blowing device, installed under the clean air box, including air bag, pulse valve, pulse controller, etc.
BMD type bag filter is generally operated under negative pressure. After the dusty air is sucked into the dust collector, it will diffuse into the entire volume of the dust box. Clean air passes through the filter bag, enters the clean air box through the Venturi tube at the filter bag mouth, and is then discharged through the clean air outlet. Dust is trapped outside the filter bag, and some dust can fall into the ash hopper by gravity, while another part will adhere to the filter bag. After a large amount of dust adheres to the dust removal filter bag, it will increase the resistance of the equipment. To maintain the normal operation of the equipment, the dust on the filter bag should be timed. This dust collector adopts a pulse back blowing system. Compared with mechanical vibration cleaning or low-pressure back blowing cleaning, this method has much better dust cleaning effect and no moving components, which can reduce maintenance workload.

After a large amount of dust adheres to the dust removal filter bag, it will increase the equipment resistance. To maintain the normal operation of the equipment, it is necessary to regularly clean the dust on the filter bag. This dust collector adopts a pulse back blowing system. Compared with mechanical vibration cleaning or low-pressure back blowing cleaning, this method has much better dust cleaning effect and no moving components, which can greatly reduce maintenance workload.
