Description

[0001] The present invention relates to a filter for turbine,

[0001] The present invention relates to a turbine dust filter, and more particularly, to a turbine that can appropriately protect a turbine by dampening foreign substances generated on the turbine, facilitate insertion and disassembly of a non-woven filter, To a dust-removing filter for a turbine.

Typically, the turbine is operated with one or more filters upstream of the suction duct or housing for the air compressor or other component. Since the filter has a filter frame for supporting the inner filter medium, it frequently breaks due to pressure or the like, and it is difficult to replace the filter, so that the filter is discarded and the whole is replaced.

For example, Korean Patent Laid-Open Publication No. 2001-0016820 discloses a filter medium 10 having a plurality of corrugated ends 11 and 12 and a pair of upper and lower caps 20 and 30 serving as a casing for accommodating the filter media. And the inner and outer cores 40 and 50, the embossing is performed along the periphery of the outer corrugations 12 of the filter media 10 to form the upper and lower caps 20 and 30 and the inner and outer cores 40 and 50 are formed by injection molding of synthetic resin and then the upper and lower caps and the inner and outer cores are inserted into the upper and lower caps and the inner and outer cores, And a hot melt process is performed on the outer side of the inner and outer cores to the wrinkles 11 and 12 of the filter media by a synthetic resin material to produce an air filter for the air filter for intake air purification.

However, in such a method for manufacturing an air filter for purifying the intake air of a gas turbine, the filter can not be actively replaced, so that the entire replacement has to be performed, and the bearing capacity due to pressure is weak and frequent breakage can not be achieved.
