Description
Technical Field
The utility model belongs to the technical field of bag filter structure technique and specifically relates to indicate a bag filter with dewatering function.
Background
The air inlet chamber filter of the gas turbine power plant mainly plays a role in filtering air. Air in the atmosphere enters from the bag-type air inlet surface, the air which comes out from the outflow surface and is firstly filtered enters from the channel of the fine-filtered air inlet surface again, and after being filtered by the glass fiber filter paper, clean air enters the following combustion engine for use. The conventional bag type filter mainly plays a role in rough filtration, protects precision and reduces the use cost of fine filtration for replacement of customers.
The conventional bag filter is composed of non-woven fabrics and a frame, has a filtering function, and does not have the functions of water removal and dehumidification.
Because the air contains moisture, the moisture content of the air is higher especially in special environments such as coastal areas, plum rain seasons and the like. When the gas turbine works, the air inlet system can suck a large amount of air containing moisture, so that the surface of the bag filter can adsorb a large amount of moisture, the increase of the resistance of the bag filter is accelerated, meanwhile, a large amount of moisture flows to the fine filter, the increase of the resistance of the fine filter is also accelerated, the service cycle of a product is shortened, and the use cost of customers is increased.
There is a need for improvements in the prior art.
