Industrial waste gas dust cylinder dust remover

Product Introduction

Industrial waste gas dust cylinder dust remover cylinder as a filter element or with a pulse jet. According to the installation method, the filter can be divided into inclined insert type, side loading type, lifting type and jacket type. According to the filter barrel material, it can be divided into long fiber polyester filter barrel filter, composite fiber filter barrel filter, anti-static filter barrel filter, flame retardant filter barrel filter, coated filter barrel filter, nano filter barrel filter, etc.

Product structure

The structure of the drum type dust collector is composed of air inlet pipe, air exhaust pipe, box, ash hopper, dust removal device, diversion device, air distribution plate, filter cylinder and electronic control device, similar to the air box pulse bag dust removal structure.

The arrangement of the filter cylinder in the dust collector is very important. It can be arranged vertically on the box flower plate or tilted on the flower plate. From the view of the dust removal effect, the vertical arrangement is more reasonable. The lower part of the flower plate is the filter chamber, and the upper part is the gas box pulse chamber. A airflow distribution plate is installed at the inlet of the dust collector.

Principle of Operation

After the dust-bearing gas enters the dust hopper, due to the sudden expansion of air flow section and the action of air flow distribution plate, some coarse particles in the air flow settle in the dust hopper under the action of dynamic and inertial forces. After the dust particles with fine particle size and small density enter the filter dust chamber, the dust is deposited on the surface of the filter material through the combined effect of Brown diffusion and screening, and the purified gas enters the clean gas chamber and is discharged by the exhaust pipe through the fan.

The resistance of the cartridge filter increases with the increase of the thickness of the dust layer on the filter material surface. When the resistance reaches a specified value, the ash is cleaned. At this time, the PLC program controls the opening and closing of the pulse valve, first of all, the lifting valve is closed, the filter air is cut off, and then the electromagnetic pulse valve is opened, the compressed air and a short time in the upper box rapidly expanded, into the filter cylinder, the filter cylinder expansion deformation vibration, and under the action of the reverse airflow scour, the dust attached to the outer surface of the filter bag is stripped into the ash bucket. After the cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber is restored to the filtering state. The cleaning room is carried out in turn, from the first room to the next cleaning for a cleaning cycle. The falling dust falls into the ash hopper and is discharged by the ash valve.

In this process, the filter cylinder must be replaced and cleaned regularly to ensure the filtration effect and accuracy, because in the filtration process in addition to the dust is blocked and some will be deposited on the surface of the filter material, increasing the resistance, so the correct replacement time is generally three to five months!
