Industrial Filter dusting Devices
The dust separation equipment is called dust-removing device. The modern industrial dust removal device can be divided into filter barrel type air dust collector and bag type air dust collector. They are suitable for fine, dry, non-fibrous dust.
Principle and classification:
1. Filter cartridge dust devices:
The filter barrel is used as the filter element. After the dust gas enters the dust collector, due to the sudden expansion of the air section and the effect of the air distribution plate, some coarse particles in the air flow settle in the ash hopper in the action of kinetic energy and inertia force, and the particles are fine. When the dust with low density enters the filter chamber, the dust is deposited on the surface of the Filter Material through the combined effects of Brownian diffusion and interception, and the purified gas enters the clean air chamber and is discharged by the fan through the exhaust pipe.
The installation methods of filter cartridge include oblique insertion type, side mounted type, lifting type, top type, filter tube material can be divided into long fiber polyester filter, composite fiber polyester filter, antistatic fiber filter, flame retardant fiber filter, high temperature resistant fiber filter, etc.
The material can be divided into long fiber polyester filter, composite fiber polyester filter, anti static fiber filter, flame-retardant fiber filter, high temperature resistant fiber filter and so on.
The structure of the filter tube type dust collector is composed of air inlet tube, exhaust tube, box body, ash hopper, ash cleaning device, flow guide device, air distribution plate, filter tube and electric control device.
1. Bag filter dust devices:
Bag filter is a kind of dry filter device. The filter bag is usually made of textile filter cloth or non-textile felt. The filter function of fiber fabric is used to filter the dust containing gas. When the dust gas enters the bag filter, the particles are large. The dust with large specific gravity is deposited by gravity and falls into the ash hopper. When the gas containing smaller dust passes through the filter material, the dust is captured and intercepted, and the gas is purified.
Bag dust collector structure is mainly composed of upper box, middle box, lower box (ash hopper), ash removal system and ash removal mechanism. In addition to the proper selection of bag material, the cleaning system plays a decisive role in bag dust collector. Therefore, the ash removal method is one of the characteristics of the bag dust collector, and also an important part in the operation of the bag filter. Ash cleaning methods include: simple manual ash cleaning, mechanical vibration ash cleaning, reverse air ash cleaning and pulse injection soot cleaning and so on.
