The characteristics of vacuum fume extractor is a kind of dust removal and purification equipment with a good rate of filtering dust containing gas with filter material. It has the characteristics of good dust removal rate, simple structure, good adaptability and stable operation.
characteristics of vacuum fume extractor The precautions for solving humidity are as follows:
First, short cleaning period: the cleaning period is short, which is conducive to the timely distribution of lime dust on the surface of the bag, reducing the possibility of bonding.
Second, the lime dust collector set bypass pipe: when the relative humidity of the air increases, the dusty air entering the dust removal system is very easy to dew, in order to avoid water gas into the dust collector bonded filter material, should be set bypass pipe, at this time can avoid the dust collector, so that the dusty air only through a layer of cyclone dust collector, and then discharged into the atmosphere. The above can be controlled automatically.
Third, the lower filter wind speed: the filter wind speed is better, will force the fine lime dust into the zigzag microhole blockage, reverse blowing ash is ineffective, long-term stay in the bag inside and form a adhesive blocking the filter hole. The use of low filter wind speed can avoid the above disadvantages.
Fourth, enough dust cleaning pressure: with the back blow air cleaning, the lime dust into the filter can be cleaned out, and enough pressure is conducive to cleaning the dust in the filter.
5. Use dust bags with caution: smooth dust bags that are not easy to stick to the lake should be selected, such as smooth polyester filter material 729, needle felt dust bags, etc.
characteristics of vacuum fume extractor is a new type of bag dust collector, which can adapt to the condition of good concentration after desulfurization, smoke temperature close to dew point, and realize the separation of flue gas dust. The dry flue gas desulphurization process requires a lot of material circulation, which requires the design of the chamber and flue of the dust collector to be optimized. Therefore, the bag dust collector not only meets the requirements of gas-solid separation of flue gas, but also facilitates the material circulation of the desulfurization system. When working, the dust containing gas enters the ash hopper from the lower part of the box. Due to the sudden expansion of the air flow area and the decrease of the flow rate, some of the dust with large particles in the air flow settles down in the dust collection bin under the action of gravity. The dust with small particles settles on the surface of the filter bag through the combined effect of inertial collision and screening on the surface of the filter bag, and the purified gas enters the upper box (net gas chamber). It is discharged from the exhaust pipe through the induced draft fan. When cleaning, the high-pressure air generated by the reverse blower is ejected, and enters the filter bag through the trumpet ejection-tube, so that the filter bag suddenly expands and generates an exciting force, so that the urea dust accumulated on the outer surface of the filter bag is immediately filtered down and falls into the dust collecting bin to achieve the purpose of cleaning.
