During the running process of a bag dust collector, as time goes by, the filtered dust accumulates in the filter bags, and its filtration effect will gradually decrease. In order to avoid such problem, a pulse valve is generally used in the system to release compressed air for back-blowing dust removal. When the pulse valve is working, the dust attached to the bag can be blown off to ensure the use effect of the bag dust collector.
Usually there is a direct relationship between the length of the dust bag and the size of the pulse solenoid valve. The pulse solenoid valve model specification is small, and the dust bag is not suitable for being too long. This is because the dust bag is designed to be too long, the blowing force is small, and the dust cleaning effect under the dust bag is not good. However, if the length of the dust bag is too short, the blowing force of the pulse solenoid valve is too large, it will easily break the bottom of the dust bag. Therefore, the corresponding pulse solenoid valve should choose a dust bag of corresponding size.
The air volume of the pulse solenoid valve is the key to how many dust bags (filter area) can be dusted, but it is not accurate to judge its dust removal performance only from the air volume of the pulse solenoid valve. Because some pulse solenoid valves cannot be turned off in time and the extra air volume is blown, in addition to increasing the loss of compressed gas and wasting energy, it has no effect on the dust removal of the dust bag.
Since 2016, we have been focusing on the combination of Internet of Things technology and bag dust removal technology, developing a smoke and dust control cloud platform and its matching bag dust removal intelligent electromagnetic pulse valve, showing the overall solution of digitalization, informatization and intelligence of traditional dust removal equipment.
