The relevant introduction of the pulse bag dust removal equipment is as follows:
Pulse spray cleaning is performed in a very short time (not more than 0.24 into the filter bag at high speed, and induces several times more air than the injected air to form an air wave, so that the filter bag is generated from the bag mouth to the bottom. Rapid expansion and shock vibration cause dust accumulation and drop ... The ash removal process is shown in Figure 22.
When blowing, the filter bag after dust removal has no dust suction effect. Due to the short blowing time, the filter bag blows dust one by one, which can almost be said to be a continuous dust collection operation.
Pulse blasting type has strong cleaning power, good cleaning effect, and can improve the filtering wind speed. The dust removal effect is related to the atmospheric pressure, the structure of the dust removal equipment, whether the jet centerline is consistent with the filter bag centerline. In cold areas, the condensation of water vapor in compressed air will affect the blowing effect and is not suitable for outdoor use.
What should be considered in the selection calculation of bag dust removal equipment?
选型不当，如果设备太大，会造成不必要的浪费；设备选型会影响生产，难以满足环保要求. There are many types of bag dust removal equipment, and the selection calculation is particularly important. Improper selection, if the equipment is too large, will cause unnecessary waste; equipment selection will affect production and it is difficult to meet environmental protection requirements.
In general, you should understand the basic process parameters of the flue gas before calculation, such as the flow rate, properties and concentration of dust-containing gas, as well as the degree of dust dispersion, wettability and viscosity. After understanding these parameters, by calculating the filtering wind speed, filtering area, filtering material and equipment resistance, selecting the appropriate equipment type and model, what indicators should be considered when considering the performance of the bag dust removal equipment?
The performance of bag dust removal equipment is mainly related to the filtration speed, dust removal efficiency, filtration resistance and dust removal method.
In actual operation, the filtration speed is determined by the type of filter material, the size of the dust particles, the physical and chemical properties, and the cleaning method. High filtration speed will increase the pressure difference between the two sides of the filter material, squeezing fine dust that has adhered to the filter material in the past, reducing the dust removal efficiency, falling below the specified emission value, or abrading the single fiber of the filter material, especially Accelerate the damage of glass fiber filter materials; if the filtration speed is small, the volume of the dust removal equipment will increase, and the investment will increase.
Related introduction of pulse bag dust removal equipment, How to determine the amount of air handled by the bag dust removal equipment?
When determining the amount of gas to be processed by a bag type dust removal device, the gas amount Ie under industrial and mining conditions first requires the actual amount of gas to be measured, and also the air leakage of the dust removal device itself. These data should be determined based on the actual operating experience or test data of the existing plant. If there is no necessary data, the amount of air mixed in the gas collection hood can be increased according to the amount of gas generated during the production process
