Principle and Application of Jet Dust Collector Bags

1. Application fields of jet dust collector bags

Due to the serious pollution in recent years and the frequent occurrence of haze weather, jet dust collector bags are widely used in major manufacturers. Jet dust collector bags are suitable for the following occasions: dust removal of calcium carbide furnace, dust removal of various electric furnaces in ferroalloy plants; flue gas purification of iron and steel plants; dust removal of coal-fired boilers and small boilers in power plants; dust removal of garbage incinerators; high-temperature flue gas dust removal of smelters; flue gas purification of aluminum plants; dust removal at the tail and head of the rotary kiln of cement plants; dust removal from the tail gas of carbon black plants, etc. Its application field is characterized by high temperature and large flue gas volume.

2. The principle of jet dust collector bags

The jet dust collector bags consist of a frame box filter bag cleaning device, a compressed air device differential pressure device and an electric control device. The main difference between jet dust collector bags and other bag dust collectors is the dust removal device. When the jet dust bag equipment is working normally, the dusty gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, some of the coarser dust particles fall into the ash hopper due to inertia or natural settlement, and most of the remaining dust particles follow the airflow and ascend into the bag room. After being filtered by the filter bag, the dust particles are retained on the outside of the filter bag. The purified gas enters the upper box from the inside of the filter bag, and then is discharged into the atmosphere through the valve plate hole and the exhaust port, so as to achieve the purpose of dust removal. Because the jet dust collector bag equipment is divided into several box areas, the above processes are carried out box by box. When one box area is cleaning dust, the other box areas are still working normally, ensuring the continuous normal operation of the jet dust collector bag. The key to the ability to deal with high-concentration dust is that the time required for this strong dust removal is extremely short (only 0.1 to 0.2 seconds for one injection).

3. Development of jet dust collector bags

At this stage, the rapid development of the dust removal industry inevitably requires people to invest more financial and material resources in it, but what we invest in is only the funds in the research and development process. When our efforts have reached a stage, the development of dust collectors must be moving towards a direction of higher speed, more stability and more cost-saving. Therefore, the emergence of jet dust collector bags has actually reduced the production and application costs to a large extent. From this point of view, such an investment is worth advocating and promoting.
