Embodiment 1

[0025] see figure 2 , the fine filter cartridge dust removal device of the gas engine air intake filter system provided in this embodiment includes a sealing cover 100 , a compressed air pipeline 200 and a blowback valve 300 . Among them, the sealing cover 100 is mainly used to cover the air outlet end of the fine filter cartridge to seal the air outlet of the fine filter cartridge. , disc shape and other arbitrary shapes, as long as the air outlet of the fine filter cartridge can be sealed; the compressed air pipeline 200 communicates with the sealing cover 100, and the blowback valve 300 is arranged on the compressed air pipeline 200 to control the direction of the compressed air pipeline 200. Compressed air is sprayed into the fine filter cartridge for back blowing and dedusting.

[0026] When in use, you only need to cover the sealing cover 100 on the air outlet end of the fine filter cartridge, and then open the blowback valve 300, the compressed air in the compressed a...

Embodiment 2

[0030] see image 3 , the fine filter cartridge dust removal device of the gas engine air intake filter system provided in the second embodiment of the present invention, on the basis of the first embodiment, further includes an atomizing nozzle 400 , a desalinated water pipeline 500 and a valve 600 . Wherein, the atomizing nozzle 400 is arranged inside the sealing cover 100 and connected with the desalinated water pipeline 500 . The valve 600 is arranged on the desalted water pipeline 500 to control the desalted water pipeline 500 to spray desalted water into the inside of the fine filter cartridge after sealing (that is, behind the air outlet end cover seal cover 100 of the fine filter cartridge), and through the atomization nozzle The 400 atomizes the desalinated water, humidifies the injected compressed air, and realizes cleaning and dedusting. The valve 600 can be a manual valve or a solenoid valve.

Embodiment 3

[0035] see Figure 4 , the arrow indicates the direction of liquid or gas flow. The dust removal device for the fine filter cartridge of the air intake filter system of the gas turbine provided by the third embodiment of the present invention, on the basis of the second embodiment above, further includes a dust collection device, and the dust collection device includes a suction cylinder 700 and a vacuum cleaner 800 . The suction cylinder 700 is adapted to the shape of the fine filter cartridge 10 , with one end open and covered on the air inlet end of the fine filter cartridge 10 . The suction cylinder 700 is provided with one or more suction holes, and the vacuum cleaner 800 is connected with the suction cylinder 700 through the suction holes, and sucks the dust on the outer surface of the fine filter cylinder from the suction port. The suction cylinder 700 can be connected with multiple vacuum cleaners 800 (three are shown in the figure).

[0036] The above-mentioned suctio...

Abstract

The invention discloses a refined filtration drum dedusting device and a refined filtration drum dedusting method for an inlet air filtering system of a gas turbine. The refined filtration drum dedusting device comprises a sealing cover, a compressed air pipeline and a back-flushing valve, wherein the sealing cover covers an air outlet end of a refined filtration drum and used for sealing the air outlet of the refined filtration drum; the compressed air pipeline is communicated with the sealing cover; and the back-flushing valve is arranged on the compressed air pipeline and used for controlling the compressed air pipeline to spray compressed air into the refined filtration drum to perform back-flushing dedusting. According to the refined filtration drum dedusting device and the refined filtration drum dedusting method, the refined filtration drum can be cleaned effectively, the phenomenon of the increase of total pressure difference of the air suction system of the gas turbine, caused by pollution of the refined filtration drum, is avoided, the service life of the refined filtration drum is prolonged, the power generation cost of the gas turbine is reduced, the power generating efficiency of the gas turbine is improved, the adaption ability of the machine set to severe weather interferences such as haze, sandy wind, rain and snow and catkin is improved, and the operating safety and the operating stability of the machine set are improved.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device and method for a fine filter cartridge of a gas turbine intake filter system. Background technique [0002] Gas turbine, or gas turbine, is an internal combustion power machine that uses continuously flowing gas as the working medium to drive the impeller to rotate at high speed and convert the energy of the fuel into useful work. It is a rotary 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] Such as figure 1 As shown, the air intake filter system of SGT5-2000E (V94.2) gas turbine is usually designed with 2 levels, the first level is the antifreeze compartme...
