Dust Collection Principle
It is a device where dust is piled up in the filtering bleb by passing exhaust gas that contains dust through many installed filtering blebs. Dust collection efficiency is high and a stable and continuous operation is possible. It can process much air volume through the adjustment of filtration rate. The harmful gas enters the housing through squeezing or absorption and the clean air is emitted to the upper part through the pipes.
Although the filtering bleb itself contains some dusts, the more important role is the dust layer that quickly accumulates on the cloth applying as a supporting system. Therefore, small dust and dusts of high concentration is piled up more efficiently due to the dust layer and this piled up dust is emitted by a mechanical device. The scope of the processing gas quantity is 3m cubed/min or more and the dust collection efficiency is a maximum of 99%. The material of the filtering bleb must be chosen by considering the properties and temperature of the harmful gas.

Characteristics
- · The dust collection efficiency regarding particles is high and many forms of dust piled up
- · Can be used for high concentration harmful air and can process diverse capacities.
- · Can use textile for high efficiency pile up of 1um or less dust and gas pollution or can use processed granular filter.
- · Moist materials, moist enrichment and absorbed components need the occurrence of crusty caking or plugging of the filter or a special facility.
- · Life expectancy shortened if processed in high temperature, acid/alkali dust or gas.
- · If dust that can be easily oxidized is piled up, there is danger of fire or explosion.
