Cement Factory Pulse Jet Bag Filter Dust Collection Equipment
Pulse Jet Bag Filter Introduction
Bag type dust collector is a kind of dry dust filtering equipment, which is mainly used for flue gas purification, dust treatment (non-fibrous) and material recovery in industries such as cement, metallurgy, building materials, machinery, chemical industry and electric power. +8615617816797 The core part of the entire dust removal work is a series of filter bags installed inside the box. The filter bags are made of woven filter cloth or non-woven felt. When the dust-containing gas enters the dust collector through the air inlet, the fiber fabric is filtered. The particles in the gas are filtered under the action, and the dust with large and specific gravity settles down due to its own gravity and falls into the ash hopper. The fine dust particles are blocked when the gas passes through the filter bag, so that the gas is purified and Prescribed emission standards.
Selection Basis of Bag Filter
For the dusty gas produced under different production conditions, a suitable type of dust collector should be used for purification treatment, so as to achieve the best purification effect. If the equipment is too large, it will cause unnecessary waste. Small, will affect production and fail to meet environmental protection requirements. The main selection basis is as follows:
1. Temperature of dusty gas
The temperature of the dusty gas is the main basis for the selection of the dust collector. If the intake air temperature is different from the design temperature, it will cause serious consequences. When the gas temperature is too high, the filter bag will be burned and deformed. For high-temperature gas, it must be cooled below the temperature that the filter material can withstand. Condensation will occur when the gas temperature is too low, so the gas temperature must be kept above 20 ° C.
2. Handling air volume
The air volume is the volume of gas that the dust removal equipment can purify in a unit time. Units are cubic meters per hour m3 / h or standard cubic meters Nm3 / h per hour. This is one of the main reasons for the selection of dust collectors.
3.Inlet dust concentration
It refers to the dust concentration in the gas at the air inlet, which is determined by the production process of the dust point. In the selection, it is an important factor behind the air volume. The unit is g / m3 or g / Nm3. When the dust concentration at the inlet is too large, consideration should be given to the installation of pre-dust removal equipment.

| Note 1: Net filtration area means the area of one chamber during dust removing. |
| 2: The compressed air consumption is based on supply of compressed air pipe from an air compression station. The consumption should be considered to be 1.3 times more if the supply is provided by an independent air compressor. |
