Bag dust collector

1. I. Applicable scenarios of small bag filters

Small bag filters are generally suitable for decentralized equipment in factories, such as reaction vessels, feeding machines, polishing and grinding, furniture manufacturing, welding, construction crushing, and other industries.

1. Characteristics of small bag filters

The small bag dust collector is compact, easy to transport and install, and boasts an elegant appearance. It can be made of various materials such as carbon steel with plastic spraying, carbon steel, and stainless steel. The equipment's air volume, wind pressure, size, and emission standards can be customized according to customer requirements, with the general emission concentration meeting 10mg/m3. The equipment features high automation, requiring no manual intervention during operation.

III. Structure of small bag filter

(1) Flower board The flower plate is made of 5mm thick carbon steel with reinforcing ribs, providing strong resistance to bending during operation. The processing of the flower plate holes is rigorous, meeting precision requirements. The notch treatment of the flower plate holes also follows extremely strict process requirements to ensure that the flower plate and the filter elements are seamlessly fitted together. The flower plate and the shell are welded together to prevent dust leakage.

(2) Air purification chamber The clean room module comprises a perforated plate, a dust removal system, and an access door. The clean room module is designed as a factory pre-assembled component to ensure installation compatibility and leak-free welding.

(3) Dust-containing gas chamber The dust-containing chamber is the lower shell module of the dust collector, which contains filter elements ranging from the top of the ash hopper to the perforated plate. The dust-containing chamber module is equipped with reinforcing ribs to ensure operation under design pressure.

(4) Filter bag The type, specification, model, and quantity of the filter bag are selected according to the emission standards required by the customer. The top-loaded spring expansion ring port filter bag adopts a top-loaded spring expansion ring port design, which can fully ensure the sealing between the filter bag and the perforated plate. At the same time, this structure makes it easier to install and remove the filter bag without requiring special tools.

(5) Pulse jet system

1) Injection pipe Pulse jet dust removal involves the direct injection of a reverse-blowing gas pulse from the top center of each filter bag, dislodging the dust accumulated on the bag surface. The online gas pulse generates an instantaneous "shock wave" and a Venturi effect, effectively loosening and sliding off the accumulated matter on the outer surface of the filter bag. This restores the flux of the bag.

2) Pulse air bag The pulse air bag is provided together with the pulse valve, solenoid valve, mounting plate, and other components. The air bag is processed from carbon steel pipe to ensure long service life; it has also undergone rigorous factory testing to ensure that the valve operates normally and without any leakage.

3) Controller and instrument electrical The time-sequential ash removal controller can automatically control the ash removal of the pulse valve, and also allows manual setting of ash removal time and interval. The controller operates with a voltage of 220V. The pulse time and pulse interval can be set and adjusted according to actual working conditions.
