Description

Dust collector reduction apparatus [Dust attachment reduction apparatus}

The present invention relates to a dust collector DUST attachment reduction device, and to a dust collector DUST attachment reduction device for removing dust contained in the gas to be treated and discharged to the outside.

In general, there are a method of collecting dust in the dust-containing gas is a wet dust collection method and a dry dust collection method, and among these, a dust collector using a filter bag is widely used as a dry dust collection method.

The dust collector using the conventional filter bag is sealed from the outside and has a cylindrical or rectangular housing in which a partition is installed. The interior of the housing is divided into an intake chamber into which the dust-containing gas is sucked by the partition wall and an exhaust chamber which is a passage of the gas from which the dust is removed. An inlet for inhaling the dust-containing gas is provided in the lower side of the intake chamber, and an exhaust port for discharging the gas from which dust is removed is provided in the exhaust chamber. Inside the intake chamber, a cylindrical filter bag for filtering a gas containing dust is installed vertically, and an upper end of the filter bag is suspended in a partition wall.

The flow of dust-containing gas in the conventional dust collector including the above configuration is as follows.

The dust-containing gas generated from the dust generating source is sucked into the intake chamber through the intake port provided under the intake chamber side of the housing due to the back pressure generated by the air intake means such as a fan provided outside the housing. The dust-containing gas sucked from the lower part of the intake chamber forms an upward air flow toward the exhaust port by the back pressure of the air intake means. The dust-containing gas passes through the cylindrical filter bag as it rises from the bottom of the cylindrical filter bag to the top, in which dust is filtered by the cylindrical filter bag, and the dust-free gas is introduced into the exhaust chamber. The gas flowing into the exhaust chamber is discharged to the outside through an exhaust port provided in communication with the outside from the exhaust chamber.

In such a conventional dust collector, dust having a large particle diameter included in the gas is attached to the surface of the cylindrical filter bag, thereby lowering the dust collection efficiency of the dust collector, thereby requiring frequent replacement of the cylindrical filter bag, thereby increasing maintenance costs. There is this.

The present invention is to solve the problems as described above to prevent the dust of the large particle size contained in the gas flowing into the dust collector by the inhaler attached to the filter bag to prevent wear and damage of the filter bag, An object of the present invention is to provide a dust collector DUST attachment reduction device capable of improving dust collection efficiency.
