BAG FILTER
Filter dust collectors use filter cloths as filters, and by collision, blocking, diffusion, and static electricity mechanisms,
It is a traditional air pollution prevention facility that removes fine particles of Hamjin gas.
Filter dust collectors are also called back filter dust collectors, filter dust collectors, and back filter dust collectors.
The device sucks in air containing dust and passes it through several filter cloths to collect dust.
Over time, the dust layer accumulated on the filter cloth acts as another filter, which rather increases the collection efficiency of fine dust.
However, an excessive layer of dust over a long period of time may cause serious resistance, preventing air from flowing.
Therefore, the filter cloth must be cleaned and readjusted at an appropriate time, and the method of spraying compressed air into the filter cloth with a device called Air Pulse Jet is most often used.
If the filter dust collector is well designed and accurately manufactured and operated properly, it can have a filtration efficiency of more than 99% based on the weight of the dust.
In some cases, high efficiency of 99.9+% may be exhibited.
- It is most commonly used in workplaces dealing with minerals, wood, cement, chemicals, pharmaceuticals, plastics, food, feed, grain, milling, fertilizer, etc.
01
product characteristic advantages of backfiltersVarious forms of dust can be collected, and the dust collection efficiency for fine particles is high.
The rate of increase in pressure loss is gentle, so high concentrations of dust can be treated.
It can operate stably for a long time.
Various capacities of dust can be treated.
02
product characteristic disadvantages of backfiltersThe pressure loss is rising slowly
be capable of treating high concentrations of dust
Backfilter necessity
In addition to strengthening national atmospheric environmental standards at the level of advanced countries for fine dust and order of dioxide, the Ministry of Environment Since 2010, the standards for allowing air pollution emissions at workplaces have been strengthened. With the implementation of the revised Air Environment Conservation Act, sulfur oxides and nitrogen oxides, which are major indicators of air environment standards, are As the standards for allowing air pollutants to be discharged have been greatly strengthened, backfilters are required in order to strictly apply these standards at workplaces.
