Problems solved by technology
[0003] During the long-term operation of the gas turbine, a large amount of dust will be adsorbed on the surface of the filter cartridge, causing its pollution. Especially when the air humidity is high, the dust will adhere to the surface of the filter cartridge. Cannot clean the filter cartridge
When the filter cartridge is seriously polluted, the total pressure difference of the gas turbine intake system will increase significantly, on the one hand, the service life of the filter cartridge itself will be shortened, and on the other hand, the power generation efficiency of the gas turbine will be reduced

The invention discloses a spiral filter cartridge of an air inlet system of a small gas turbine, and relates to the technical field of dedusting devices. The spiral filter cartridge comprises a filtercartridge body. An air inlet is formed in one axial end of the filter cartridge body. A sealing cover is arranged at the other axial end of the filter cartridge body. A filter cartridge cleaning mechanism is arranged on the sealing cover and comprises a brush body, a lifting mechanism, a compressed air pipeline and an air valve. The lifting mechanism is arranged on the sealing cover and is connected with the brush body so as to drive the brush body to move up and down in the axial direction of the filter cartridge. The compressed air pipeline communicates with the sealing cover. The air valveis arranged on the compressed air pipeline. Nozzles are arranged at the ends of the compressed air pipeline and are located in the filter cartridge body. According to the spiral filter cartridge, back-blowing dedusting and the brush body are combined to flush a filter element so as to clean the filter cartridge body, so that the service life of the filter cartridge is prolonged, and the power generation cost of the gas turbine is reduced.
Description
technical field [0001] The invention relates to the technical field of dust removal devices, in particular to a spiral filter cartridge of a small gas turbine intake system. Background technique [0002] The gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at a high degree, and converts the energy of the fuel into useful work. It is a rotating impeller heat engine. The air intake system of the gas turbine is usually arranged on the top of the gas turbine generator room. Its function is to filter the dust in the air, initially separate the liquid droplets in the air, and supply the filtered clean air to the gas turbine compressor to ensure the normal and stable operation of the gas turbine. [0003] During the long-term operation of the gas turbine, a large amount of dust will be adsorbed on the surface of the filter cartridge, causing its pollution. Especially when the air humidity is h...
