鋼スラグ用バグフィルターの除塵効果は以下のとおりです。

The dust removal effect of steel slag bag filter is related to many factors, but mainly depends on the filter material. The filter material of bag filter is cloth or felt made of synthetic fiber, fiber or glass fiber. If necessary, sew the cloth or felt into a cylinder or flat filter bag. According to the nature of flue gas, the filter material suitable for application conditions is selected.

鋼スラグ用バグフィルターの利点

Generally, when the flue gas temperature is lower than 120 ℃, the filter material is required to have acid resistance and durability; In the treatment of high temperature flue gas (< 250℃ ) Graphitized glass fiber cloth is mainly used; In some special cases, carbon fiber filter material is selected. In the case of coal and iron stone, explosion-proof treatment is also needed, so the filter material of silk should be selected for the dust removal bag.

 

2.鉄鋼焼結機の集塵機

The dust collector of iron and steel sintering machine is an ideal dust removal equipment to solve the problem of dust containing flue gas at the end of sintering machine. According to the characteristics of large exhaust volume, high gas temperature and high dust concentration at the end of sintering machine in sintering plant, when selecting the dust collector system for sintering machine, it is analyzed according to different conditions of sintering machine, so as to achieve better dust removal effect of bag filter.

It is suitable for flue gas treatment in electric power, building materials, metallurgy, chemical industry and other industries.

The dust remover of iron and steel sintering machine is widely used in the flue gas treatment of electric power, building materials, metallurgy, chemical industry and other industries, especially for the flue gas with big storm and high temperature. It combines the characteristics of chamber back blowing and pulse cleaning, overcomes the shortcomings of ordinary chamber back blowing intensity and general pulse cleaning dust re adsorption, and the lengthened dust removal filter bag gives full play to the strong cleaning effect of compressed air. It is a large dust removal equipment with high dust removal efficiency, small floor area, stable operation, reliable performance and convenient maintenance.

 

3.高炉ガス集塵機

The blast furnace gas dust collector of iron and steel adopts the technology of pulse injection dust cleaning by stopping air in different rooms, which overcomes the shortcomings of conventional pulse dust collector and reverse blowing dust collector in different rooms. It has strong dust cleaning ability, high dust removal efficiency, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, less floor area, stable and reliable operation, and good economic benefits. It is suitable for purification of dust gas and material recovery in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

The raw gas (260 ℃) from the raw gas main pipe enters into the lower box of the bag filter through the branch pipe. After mechanical separation, the gas is filtered upward through the cloth bag, and the fine dust is attached to the outer surface of the filter bag. The clean gas is collected into the upper box through the filter bag, and then enters into the hot blast stove through the clean gas branch pipe and the main pipe. When the filtering time is up, with the increase of dust on the surface of the filter bag, the resistance of the dust collector will rise. When the resistance rises to the value, the electrical control system will send out the ash cleaning signal, the pneumatic butterfly valve and upper ball valve of the outlet branch pipe will automatically close, the pulse valve will open, the nitrogen from the cylinder will be injected from the bag mouth through the injection pipe, and the filter bag will expand rapidly.

The dust on the outer surface of the filter bag is shaken off and falls into the conical ash hopper at the lower part. At the end of the pulse valve injection, the dust collector continues to remain static, so that the fine dust in the cylinder has a static settlement process. At the end of this process, the outlet branch pneumatic butterfly valve and the upper ball valve are opened, the dust collector enters the normal filtering state, and the lower ball valve is opened through the impeller feeder The dust cleaning process of a box, the opening and closing of each valve in the above process, and the dust concentration test of a single box are all controlled by PLC system, so that the repeated work can purify the raw gas.

 

4.鉄鋼プラントの集塵機

The filter bag made of porous filter cloth is used to separate the dust particles from the flue gas flow. When working, the flue gas flows through the filter bag from the outside to the inside, and the dust particles are blocked outside the filter bag.

The iron and steel industry is a major air polluter. The waste gas management of iron and steel industry implements the principle of comprehensive management. Efforts should be made to reduce energy consumption and raw material consumption, which is one of the fundamental ways to increase the emission of waste gas; the process, adopted process and equipment should be innovated to increase the emission of waste gas from consumption process; energy-saving management methods and equipment should be adopted to strengthen the management and recovery of waste gas; comprehensive use should be vigorously carried out.

At the present stage, a large number of flue gas will be discharged from the sintering machine of large steel plants in China, which will contain nitrogen, sulfur dioxide, dioxin, dust and other substances. Taking the sintering machine of 280 square meters as an example, the content of dust discharged into the atmosphere is 150mg / Nm3. According to this calculation, it will cause great pollution to the environment. At present, China has formulated detailed requirements and standards for energy conservation and emission reduction, and put forward suggestions for environmental protection According to the current standard of our country, the dust concentration discharged into the atmosphere is less than 50mg / Nm3, and the bag filter is an important part to achieve this requirement.
