Small knowledge of dust collector The equipment that separates dust from the flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector , and the dust removal efficiency. At the same time, the price, operation and maintenance costs, length of service life, and ease of operation and management of the dust collector are also important factors in considering its performance.
Purpose of dust collector : Dust collectors are commonly used in boilers and industrial production facilities. Dust collectors are divided into the following five categories according to their working principles:
(1) Mechanical dust collectors include gravity dust collectors, inertial dust collectors, and centrifugal dust collectors.
(2) Washing type dust collector includes water bath type dust collector, foam type dust collector, venturi tube dust collector, water film dust collector and so on.
(3) Filter type dust collector includes bag dust collector and particle layer dust collector, etc.
(4) electrostatic precipitator.
(5) Magnetic dust collector.
Bag dust collectors are more commonly used in industry today. (Fabric filter)
Technology of bag filter:
Definition: The technology of filtering dust with filter bags.
Filter bag material: natural fiber, chemical synthetic fiber, glass fiber, metal fiber.
Form: The gas is from the outside to the inside of the filter bag, and the dust is on the outside surface of the filter bag. The gas is from the inside to the outside of the filter bag. The dust is on the inside surface of the filter bag.
