PTFE Japan Toray film covered welding dust removal filter cartridge

1. Filter cartridge structure
The filter element of the cartridge type dust removal filter element is the filter cartridge. The structure of the filter cartridge is divided into four parts: the top cover, the metal frame, the pleated filter material and the base. The filter cartridge is the designed length of filter material folded into folds, and the head and tail are bonded into the cartridge; The inner and outer parts of the cylinder are supported by a metal frame, and the upper and lower parts are fixed by a top cover and a base. The top cover is fixed Bolt and Washer 。 The performance and overall dimensions of the round filter cartridge are shown in the figure.
2. Dust collector structure
The dust remover is composed of air inlet pipe, air exhaust pipe, box, ash hopper, ash cleaning device, filter cartridge and electric control device. The arrangement of the filter cartridge in the dust remover is very important. The filter cartridge can be vertically arranged on the box flower plate or obliquely arranged on the flower plate, fixed with bolts, and equipped with a rubber pad; The lower part of the flower board is a filter chamber, and the upper part is a clean air chamber. In addition to fixing the filter cartridge with bolts, the more convenient methods are automatic locking device and rubber compression device, which are very convenient for installation and maintenance.
3. Operating principle of cartridge filter
After the dusty gas enters the dust hopper of the dust remover, due to the sudden expansion of the air flow section, part of the coarse dust particles in the air flow settle down under the action of gravity and inertia force. After the fine particle size and small density dust particles enter the filter chamber, the dust will be deposited on the surface of the filter material through Brown diffusion, screening and other comprehensive effects. The purified gas enters the air purification chamber and is discharged by the exhaust pipe through the fan.
