Bag dust collector, also known as bag dust collector, is an efficient and reliable dust filtration equipment, the following is a detailed introduction to the bag dust collector:
1. the working principle
The working principle of the bag filter is to filter the dust-containing gas by using the filtration effect of the fiber fabric. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy ratio settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. As the dust on the surface of the filter bag continues to increase, the program-controlled instrument begins to work, opening the pulse valve one by one, so that the compressed air is sprayed through the nozzle, cleaning the filter bag, and the filter bag suddenly expands. Under the action of reverse air flow, the dust on the surface of the cloth bag is quickly separated from the filter bag and falls into the ash bin, which is discharged by the ash discharge valve.
2. structure composition
The cloth bag dust collector is mainly composed of upper box, middle box, ash hopper, air inlet pressure equalizing pipe, supporting filter bag, spraying device, unloading device, etc. Among them, the filter bag is the core component of the bag dust collector, and its material and performance directly affect the dust removal effect and service life of the dust collector. Common filter bag materials are polyester, polypropylene, nylon, aramid, etc., according to the working environment and the nature of the dust, you can choose different filter bag materials.
3. performance characteristics
High dust removal efficiency: the dust removal efficiency of the bag dust collector can generally reach more than 99.9%, and the dust removal concentration can be greatly lower than 30mg/m³.
Large amount of air: bag dust collector can handle a large number of dust-containing gases, suitable for industrial production of various scales.
Stable operation: the structure design of the bag dust collector is reasonable, stable and reliable operation, and the failure rate is low.
Simple operation: The operation of the bag dust collector is simple and convenient, easy to maintain and manage.4. Application field
Bag dust collector is widely used in mining, cement, building materials, grain, steel, electric power, chemical, food and other industries of environmental protection equipment. In the iron and steel industry, the bag dust collector is mainly used for the dust removal treatment of the dust containing gas produced in the process of iron making, steel making and steel rolling. In the power industry, the bag dust collector is mainly used for flue gas dust removal in coal-fired power plants; In the chemical industry, the bag dust collector can effectively remove dust and harmful gases; In the food industry, the bag dust collector can effectively remove the dust generated in the process of crushing, screening, mixing and packaging of raw materials.
