bag filter

With the development and progress of the economy, our company's bag filter products are also being updated, and their specifications are as follows:

Good sales, working principle

Dust gas enters the ash hopper from the air outlet, and dust particles and condensed dust directly fall down, while other dust gases flow upward into the box. When the filter bag with a metal frame passes through, dust will stay on the outer surface of the filter bag, and the purified gas will enter the upper cleaning chamber of the filter bag and gather in the exhaust pipe for discharge. As the filtration progresses, the accumulation of dust on the outer surface of the filter bag increases, leading to an increase in resistance. When the set value is reached, remove the dust and issue a command to remove the dust on the outer surface of the filter bag, so that it falls into the ash hopper.

Excellent, structural composition

1. Frame: mainly made of carbon steel wire or stainless steel wire, longitudinally welded by longitudinal reinforcement and support ring, including beams, columns and slant support, used to support the box, facilitate maintenance, and protect the machine in special circumstances such as natural disasters.

2. Box body: used to fix the skeleton, filter bag, and pneumatic components, including filter bag room and clean room. They are separated by flower boards, and the airflow is switched through a lift valve. Their shapes are circular and rectangular, mainly rectangular.

3. Filter bag: The core component of dust removal consists of a bag body sewn with filter material, supports, fixtures, and other accessories. It is divided into circular, flat, and irregular filter bags according to the cross-sectional shape. According to the filtering direction, it can be divided into external filtering and internal filtering.

4. Dust removal device: The key to maintaining the long-term stable operation of the dust collector includes air filters, airbags, pulse valves, etc. Different dedusting devices have different dedusting methods, such as low-pressure pulse spray, low-pressure rotary pulse spray, air box pulse spray, etc.

Drive system: The dust removal fan is the power source for generating airflow, which can be divided into positive pressure dust removal system and negative pressure dust removal system according to installation position. The commonly used negative pressure dust removal system.

Classification Method Three

According to the shape of the filter bag, filtering direction, air inlet position, pressure inside the dust collector, and dust removal method, it can be divided into different types. For example, according to the dust removal method, it can be divided into pulse blowing dust removal, back blowing dust removal, mechanical vibration dust removal, and other types.

4、 Characteristics

1. Advantages: Good dust removal efficiency, generally above 99%; Wide range of air volume processing; Simple structure, easy maintenance and operation; The cost is lower than that of electrostatic precipitators; When using high temperature resistant (based on actual reports) filter materials, they can operate at temperatures above 200 ℃.

Disadvantages: High requirements for temperature, flue gas moisture, flue gas composition, large pressure loss, large volume, high demand for steel, and high operating costs.

Fifth, the application industry

Widely used in various industrial sectors such as steel, non-ferrous metallurgy, chemical industry, machinery, building materials, transportation, etc., it is also used for the treatment of dust and waste gas in workshops, smelters, power plants, and other dust and waste gas projects.

We will strictly control every quality control and provide you with high-quality bag filter products and thoughtful services. Your trust and support are our driving force forward.
