Detailed introduction of DMC series single machine pulse bag dust collector

The DMC series single machine pulse bag filter adopts the technology of high-pressure (0.5~0.7MPa) high flow pulse valve to blow and clean the dust one by one through the filter bags. It has the advantages of small volume, large processing air volume, compact structure, and easy use. The structure mainly consists of a fan, a box, an ash discharge device, a control system, etc., all of which are placed inside a circular steel plate welded box. It is painted for rust prevention, has a beautiful appearance, a scientific structure, and is easy and reliable to operate. Widely used in mining, electric furnace smelting, machinery manufacturing, chemical products, cement and building materials, grain processing and other industrial and mining enterprises for warehouse top, warehouse bottom, belt conveyor and local dust source dust removal.

Working principle of DMC series single machine pulse bag dust collector:

The dusty gas enters the ash hopper through the air inlet or enters the filter bag chamber through an open flange. The dusty gas is filtered through the filter bag into clean gas and enters the clean gas chamber. It is then discharged by the fan through the exhaust port of the clean gas chamber. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag filter to continuously rise. In order to ensure that the equipment resistance does not exceed 1200Pa, the DMC series single machine pulse bag filter can continue to work, and the dust on the filter bag needs to be regularly removed. Dust cleaning is a process in which the pulse valve is activated by the program controller in a timed sequence to compress air (0.5~0.7MPa) inside the air bag. The compressed air (referred to as primary air) is then blown out through the holes of the blowing tube and induced into the filter bag through the Venturi tube. The surrounding air (referred to as secondary air), which is several times the primary air, rapidly expands in an instant and is shaken off by the opposite direction of the airflow, achieving the purpose of dust cleaning.

Advantages of DMC pulse bag filter:

1. Huakang Zhongtian adopts the JB/T8532-2008 standard design, which has strong dust cleaning ability; The filter bag adopts a rising ring design, which is easy to install and seal tightly.

2. High quality cold drawn steel wire and multi-point welding automatic production line are used, and rust prevention treatment is carried out on the skeleton surface through galvanizing, spraying or organic silicon treatment processes. The bag skeleton produced by Huakang has high rigidity, no welding burrs, reduces the mechanical wear of the bag, and the bag can be used for a longer time.

3. The pulse bag filter adopts the maintenance method of opening the cover, making it easier and more convenient to replace the filter bag.

4. This device adopts PLC or program controller to control the pulse cleaning system, with high automation and safe and reliable operation.

Key points for selecting DMC series single pulse bag filter:

a. The main technical parameters for selecting a bag filter are air volume, gas temperature, dust concentration, and humidity. According to the relatively high values of air volume, gas temperature, and dust concentration in the process design, based on the principle of slightly smaller values than those in the technical performance table, the corresponding dust collector model is the required dust collector model

b. The gas consumption in the table refers to the situation when the factory supplies gas centrally. If an air compressor is used separately, the gas consumption in the table should be increased by 1.5 times.

c. The air consumption listed in the compressed air consumption column refers to the larger air consumption of the equipment model.
