Description

A filter cartridge dust collector

technical field

The utility model relates to the technical field of industrial dust removal, in particular to a filter cartridge dust collector.

Background technique

The equipment that separates industrial dust from flue gas is called industrial dust collector or industrial dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. Commonly used industrial dust removal equipment includes bag filter, cartridge filter, electrostatic precipitator and cyclone dust collector. Industrial dust collectors are widely used in metallurgy, mining, building materials, foundry, chemical, tobacco, electronics, asphalt, cement, machinery, grain, mechanical processing, boilers, and other industries for the recovery and reuse of dust purification bodies and dust-containing gases in workshops.

The filter cartridge dust collector is mainly composed of air inlet pipe, exhaust pipe, box body, ash hopper, dust cleaning device, diversion device, air flow distribution distribution plate, filter cartridge and electric control device. After the dust-laden gas enters the ash hopper of the dust collector, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, some coarse particles in the airflow settle in the ash hopper under the action of dynamic and inertial forces; after the dust particles with fine particle size and low density enter the dust filter chamber , through the combined effects of Brownian diffusion and sieving, the dust is deposited on the surface of the filter material, and the purified gas enters the clean air chamber and is discharged from the exhaust pipe through the fan.

The resistance of the filter cartridge dust collector increases with the increase of the thickness of the dust layer on the surface of the filter material. When the resistance reaches a certain value, the dust will be cleaned. At this time, the PLC program controls the opening and closing of the pulse valve. First, the poppet valve in the first chamber is closed to cut off the filtered air flow, and then the electromagnetic pulse valve is opened. The compressed air expands rapidly in the upper box in a short time and pours into the filter cartridge to make the filter cartridge The expansion deformation produces vibration, and under the action of reverse air flow, the dust attached to the outer surface of the filter bag is stripped and falls into the ash hopper. After the cleaning is completed, the electromagnetic pulse valve is closed, the poppet valve is opened, and the chamber returns to the filtering state. The cleaning rooms are carried out sequentially, from the first cleaning room to the next cleaning cycle is a cleaning cycle. The fallen dust falls into the ash hopper and is discharged through the ash discharge valve.

For example, the Chinese invention patent application document 201510407217.9 discloses a filter cartridge dust collector, including: a box body, a dust cleaning device arranged on one side of the box body, the box body is arranged on a bracket, and an ash bucket is arranged at the bottom of the box body. It is set at the air inlet on one side of the ash hopper, and the box is divided into a filter room and a clean room by a partition. There are several filter racks inclined upward at 5-15° in the filter room, and the filter cartridges are placed on the filter racks. One end is provided with a venturi tube, and the venturi tube extends into the clean room through the partition. The dust cleaning device includes an air storage tank, a compressed air inlet on the upper end of the air storage tank and several nozzles, and the nozzles extend into the front of the clean room. For the Venturi tubes of the filter cartridges, a gray baffle is arranged above each filter cartridge. The ash baffle is a trapezoidal stainless steel plate with a thickness of 5 mm to 8 mm. Inside the filter cartridge, along the extension of the filter cartridge The direction is fixed with a core tube with a closed upper end, the upper end of the core tube is in the shape of a cone protruding forward, a part of the cone is located in the filter cartridge, between the core tube and the filter cartridge There is a cavity.

A conventional filter cartridge dust collector is disclosed in the above-mentioned prior art. The dust removal effect of this dust collector is acceptable, but the following problems still exist:

1. The filter cartridge is tilted, and the filter cartridge fixing device also needs to be tilted. After long-term use, with the increase of dust accumulation in the filter cartridge, the weight increases, the filter cartridge is deformed, and the seal between the deformed filter cartridge and the fixing device is not strict , causing the problem of low cleaning efficiency.

2. The dusty gas coming in from the air inlet is directly sucked onto the filter cartridge and hits the surface of the filter cartridge. The filter cartridge is easily damaged and the service life of the filter cartridge is reduced.

Based on the above defects in the prior art, the inventor proposes a filter cartridge dust collector based on years of experience in scientific research and design and manufacture.
