The filter cartridge is very small because of the vibration of the filter hopper during the cleaning process. Therefore, the service life of the filter cartridge is well ensured, and the product is usually replaced in half a year. This reduces the Replacement of material costs, but also reduce the replacement of the workload.
The filter design wind speed, in fact, this parameter can be changed, it is not a fixed value, can be adjusted within a certain range, but when we use, this speed is not easily adjustable, what we need to do is According to the actual production conditions to set the size of this speed.
Generally, the factors that can affect the speed of the filter cartridge are more, such as the type of dust or some external disturbance factors. When adjusting the wind speed, these possible influence factors need to be taken into consideration, and the accuracy is higher. .
The commonly used automatic cleaning method for filter cartridges is high pressure gas pulse backflushing, mechanical vibration, and pulse backflushing. It uses the parameters preset by the controller to give a signal to the solenoid valve to instantly open and close the solenoid valve diaphragm, so that the high pressure gas enters the injection pipe. The use of gas rapid expansion force to shake off the filter surface dust, the general gas pressure we set about 6 kg force. Mechanical vibration cleaning is usually used for small single filter cartridge dust collectors. It uses the shaking force generated by the eccentric device of the dust collector to remove dust. This action needs to stop after operation.
The design wind speed of the filter cartridge is a key parameter, which is related to the operation effect of the entire dust collector. Under normal circumstances, we recommend that the design wind speed of filter paper containing wood pulp fibers should not exceed 0.6 m/min, and polyester non-woven fabrics are recommended The design wind speed is 1 meter/minute, of course, we also need to specifically consider according to the filtering dust characteristics.
