Do you know how to solve the problem of large resistance in the stand-alone bag filter?
The stand-alone bag filter usually adopts the form of water flushing and ash discharge. After the dust falls into the ash hopper, the dust is discharged through the water tank, and the dust is flushed into the ditch. In winter, if it is not used for a long time, the dust collector with side spray low pressure bag will have dust formation phenomenon, because in winter the temperature is low and the ash hopper is usually not strict, so that the flue gas can be easily condensed and desulfurized in the low temperature part. And the ash adheres to the wall of the ash hopper, causing the ash to be blocked. Therefore, in the design of the side spray low-pressure single-machine bag filter, the influence of external factors should be fully considered, and conditions such as local temperature should be considered.
The quality of the filter material is very high. Generally, the filter material needs the support of the overseas market, which increases the economic cost of the factory. Therefore, the development of the domestic single-machine bag filter is an important factor restricting the development and application of the current single-machine bag filter, and it should be implemented as soon as possible. The resistance of the stand-alone bag filter is relatively large, which is also a problem we need to solve. In addition, in the process of blowing soot, the requirements for spraying the low-pressure bag filter on the side of the solenoid valve are also very high. The quality of the solenoid valve directly affects the operation of the machine. There are many interference factors, such as air quality and power supply stability. The normal operation of the solenoid valve will also be affected. The compressed air pipeline is easy to freeze and freeze. The pipeline temperature should be fully considered in the design process to make the pipeline not easy to freeze. For very cold places, insulation and heating facilities are required.
In practical applications, the frequency of soot blowing has a great influence on the bag, which determines the length of the service life of the bag. Due to different coal quality, soot concentration will change, resulting in changes in the frequency of back-blowing soot. This requires several more modes for the stand-alone bag filter to adapt to these changes and extend the service life of the filter bag.
