A High Efficiency Cartridge Air Filter for Gas Turbines

Abstract

The invention belongs to the technical field of gas turbines, and discloses an efficient cylinder type air filter for a gas turbine, which is used for solving the problems that an existing filtering cylinder is small in filtering area and high in resistance. The efficient cylinder type air filter comprises a filtering cylinder framework consisting of an outer metal net layer and an inner metal net layer; the outer metal net layer and the inner metal net layer form the filtering cylinder framework; filtering paper is arranged between the outer metal net layer and the inner metal net layer; two ends of the filtering cylinder framework are respectively connected with seal end covers; one seal end cover is connected with a ventilation pipe which is communicated with the interior of the filtering cylinder framework; the bottom end of the ventilation pipe is connected with a gas distribution disc; gas distribution openings are formed in the side surface and the bottom surface of the gas distribution disc; the outer metal net layer is of a cylindrical structure formed by a wavy metal net layer; the inner metal net layer is of a cylindrical structure formed by a wavy metal net layer; the wave crest and the wave trough of the outer metal net layer respectively correspond to the wave crest and the wave trough of the inner metal net layer.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and specifically relates to a high-efficiency cartridge air filter for gas turbines, which is used for filtering and purifying the air introduced into the gas turbines. Meanwhile, the invention can also be used for air filtration and purification in other fields. Background technique [0002] A gas turbine is a rotary power machine that converts heat energy into mechanical work using continuously flowing gas as a working medium. In the main process of air and gas, the gas turbine cycle is mainly composed of three major components: the compressor, the combustion chamber and the gas turbine. [0003] The compressor inhales air from the external atmosphere, and pressurizes it step by step through the axial flow compressor, and the air humidity is also increased accordingly; the compressed air is sent to the combustion chamber to mix with the injected fuel to produce high-temperature and high-pr...
