Description
Technical Field
The invention relates to a box-type fine filter of a gas inlet system of a gas turbine.
Background
The filter material surface of the filter can be blocked and frozen when the filter is used in the environment states of low temperature and high humidity in winter in the north, haze, ice and snow, rime and willow wadding, the pressure difference of the filter rises abnormally, the failure rate is high, and therefore the filter cannot run well in a long period, and the normal running of the whole unit is seriously influenced.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and provides a box type fine filter of a gas turbine air inlet system.
The technical scheme for solving the technical problems is as follows: the utility model provides a box fine filter of gas turbine air intake system, including filtering the casing and setting up the filter equipment in the casing, it has air inlet and gas outlet respectively to filter casing front end and rear end, it includes interior casing and shell body to filter the casing and be provided with the heater between interior casing and the shell body it is equipped with gas flow controller to filter casing air inlet department, is provided with the blowback gas pipe in its gas outlet department, filter equipment is combination formula filter, including filter one and filter two, leaves the clearance between this filter one and the filter two, is provided with the circlip in the clearance, is provided with the abatvoix at the precision filter rear end, and this abatvoix is the setting of v type to be provided with the drier on the abatvoix.
The invention further defines the technical scheme that:
the heat insulation cotton is arranged outside the heater.
The gas flow controller comprises a flow sensor, an adjusting valve and a display controller, wherein the flow sensor detects the flow of gas passing through and obtains a flow signal, and the display controller receives the flow signal of the flow sensor.
The filter I is internally provided with a combined filter screen which at least comprises 2 filter screens arranged in concentric circles with different specifications, the filter screens are fixed on the inner wall of the filter I through a hoop,
the micro-vibrator is arranged between the two combined filter screens.
And a water removal filler layer, an adsorption filler layer and a high-efficiency wood pulp fiber filter layer are sequentially arranged in the second filter.
The invention has the beneficial effects that: according to the invention, two-stage filtration is adopted to achieve a multi-stage filtration effect, the combined filter screen is arranged in the first filter, the combined filter screens adopt filter screens with different specifications and are arranged in a superposed manner, so that a good filtration effect can be achieved, a micro vibrator is arranged between every two adjacent filter screens to assist in blowing air, so that dust and impurities in the filter screens can be effectively removed, and the filter screen holes are prevented from being blocked by dust to influence the filtration effect; the heater and the heat preservation cotton are arranged, and the filter shell is kept relatively dry through the matching of the drying layer, so that the surfaces of the filter and the filter screen are not easy to block and freeze; the air flow controller is arranged at the air inlet of the filtering shell and controls the air flow speed to reduce the temperature drop, so that the frosting phenomenon of the air inlet system of the gas turbine during operation in winter is reduced, the possibility of blockage of the air inlet system is greatly reduced, and the high-efficiency and reliable operation of a subsequent unit is ensured.
