The Operating Resistance Of ThePulse Bag Filter Is Higher Than The Control Scale

It is found that the operating resistance of the pulse bag dust collector is higher than the control scale,Pulse Bag Filter and the reason should be found from the following aspects to eliminate the fault: the dust cleaning time is short, Pulse Bag Filterthe dust cleaning cycle is too long, the dust on the filter bag cannot be removed,Pulse Bag Filter the dust collector is transferred to the filter The situation will make the operation resistance increase quickly. For the pulse bag type dust collector,Pulse Bag Filter the time used for the cleaning process (that is, the time when the pulse valve is sprayed) is the cleaning time, which can be adjusted within the range of 0.05 to 0.5s. The time of the two cleaning distances is the cleaning cycle,Pulse Bag Filter generally 0～30min. Adjust the cleaning criteria of the pulse bag dust collector, properly extend the cleaning time,Pulse Bag Filter add the amount of compressed air and induced air sprayed into the filter bag;Pulse Bag Filter shorten the cleaning cycle together and even select successive cleaning methods to make the cleaning of the filter bag more effective For completeness,Pulse Bag Filter it is useful to reduce operating resistance.

When the pulse bag filter handles high-temperature and high-humidity gas, if the gas temperature is lower than the dew point during the operation, the water vapor will condense and condense,Pulse Bag Filter so that the filter bag is wet, and many dust adheres to the filter bag surface, blocking the filter bag pores, Moreover,Pulse Bag Filter the compressed air can not be removed, forming a filter bag paste bag. The dust removal function of the dust collector with a paste bag fails, the resistance is too large,Pulse Bag Filter and the working condition deteriorates. In order to prevent dew condensation on the pulse bag filter,Pulse Bag Filter it is necessary to insist that the process gas temperature is 25 to 35°C above its dew point. When the dust collector is used for processing high-temperature and high-humidity gas,Pulse Bag Filter the temperature monitoring alarm device should be installed at the entrance to monitor, and rock wool and other thermal insulation materials should be added to the shell for thermal insulation. Before the dust removal system is suspended,Pulse Bag Filter it is necessary to completely discharge the wet gas in the dust collector and replace it with dry air to prevent condensation. That is, after the production equipment is suspended,Pulse Bag Filter the dust removal fan should be extended for a period of time before shutting down.
