The working principle of pulse stand-alone dust collector bag
The working principle of bag dust collector is a dry dust removal device, which is suitable for collecting fine dry non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. The filtering effect of the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy specific gravity settles down due to the action of gravity. , falls into the ash hopper, and when the gas containing fine dust passes through the filter material, the dust is blocked, allowing the gas to be purified.
Generally, the dust removal efficiency of new filter materials is not high enough. After the filter material is used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as sieve collision, retention, diffusion and static electricity. This layer of dust is called the primary layer. In the subsequent movement process, the first layer becomes the main filter layer of the filter material. Relying on the function of the first layer, filter materials with larger meshes can also obtain higher filtration efficiency.
As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference on both sides of the filter material is large, some small dust particles that have adhered to the filter material will be removed. Squeezing it out will reduce the efficiency of the dust collector. Besides, high resistance power will significantly decrease air volume of the dust collecting system.
Pulse stand-alone bag dust collector is used in flue gas treatment and dust removal systems in iron-making plants, steel-making plants, ferroalloy plants, refractory plants, foundries, power plants, etc. Flue gas filtration from waste incinerators, coal-fired boilers, fluidized bed boilers, etc. Asphalt concrete mixing, building materials cement ceramics lime gypsum and other production sites. Smelting flue gas filtration of aluminum electrolysis, lead, tin, zinc, copper and other rare metals, recovery of fine materials, and liquid-solid separation. Liquid-solid separation and fine material recovery in chemical, coke, carbon black, dyes, pharmaceuticals, plastics and other fields. Dust control and purification collection in mining, grain processing, flour, electronics industry, wood processing, etc.
Structural design of pulse stand-alone dust collector bags. Pulse stand-alone dust collector bags are generally divided into pulse dust collector bags, vibrating pulse stand-alone dust collector bags, and backflush pulse stand-alone dust collector bags according to different dust cleaning methods. Depending on the shape, there are round bag type, flat bag type, and envelope type. Pulse stand-alone dust collector bags also have different bag mouth and bag bottom designs to choose from.
Flomax dust collector bag
It is the most widely used variety among high temperature resistant dust removal filter bags. They also have the characteristics of low cost and high temperature resistance. Among them, there are two types of Flumax dust collector filter bags. Or two or more high-temperature resistant fibers are mixed and layered to achieve higher and updated physical and chemical properties. Polyester needle felt dust collector bag
In addition to the characteristics of high porosity, good air permeability, and moderate acid and alkali resistance unique to ordinary felt filter cloth, it also has very good wear resistance, so it is a felt filter material The most widely used species. Glass fiber dust filter bag is a kind of filter material with reasonable structure and good performance. The filter bag not only has the advantages of glass fiber fabric, high temperature resistance, corrosion resistance, stable size, minimal elongation and shrinkage, and high strength
