Description
Technical field
The invention belongs to gas turbine technology field, be specifically related to a kind of blade-rotation air filter for gas turbine, for carrying out filtration, purification to gas turbine inlet air, the present invention simultaneously can also be used for the air purification filter of other field.
Background technique
Gas turbine be a kind of using the gas of continuous-flow as working medium the thermal power transfer rotary power machinery that is mechanical work.In the main flow of air and combustion gas, primarily of this three large parts composition gas turbine cycle of gas compressor, firing chamber and combustion gas turbine.
Gas compressor sucks air from ambient atmosphere environment, and compresses step by step through axial-flow compressor and make it supercharging, simultaneously humidity of the air also corresponding raising; Pressurized air is pressed to firing chamber and the combustion gas of fuel mix production High Temperature High Pressure sprayed into; And then enter into turbine expansion work, promote turbine and drive gas compressor High Rotation Speed together with outer load rotor, the chemical energy achieving gas and liquid fuel is mechanical energy, and exports electric work.
The inlet stream of gas turbine blower and the combustion air of gas turbine must carry out purified treatment before being introduced into gas compressor.Modal is adopt the fabric filter of machinery to purify above-mentioned air inlet, and the corrosive and dirty particle of preventing belt enters gas compressor and turbine, thus prevents corrosion and the breakage of equipment, and the workload reducing cleaning and keep in repair.Gas turbine for the production of the energy needs a large amount of combustion airs, therefore, even the impurity of trace all can cause in use producing a large amount of sediments, so require filtration combustion air as far as possible effectively.
Along with going from bad to worse of air quality, often occur that haze weather has created the air inlet of gas turbine to have a strong impact on, if do not install coarse-grain filtering device additional, haze air directly filters through automatically cleaning filter core, blowback can be caused to lose efficacy, and accelofilter is scrapped, reduce combustion engine efficiency, and automatically cleaning filtration core is expensive, frequent replacing can reduce profit from power plant.
Such as application number be 201110448766.2 patent of invention disclose a kind of air filter, first order filter (i.e. low efficient filter), second level filter and third level filter, in described first order filter, described second level filter and the spaced gas-entered passageway being sequentially arranged in gas turbine generator group of described third level filter.Air filter also comprises interval and is fixed on multiple filter frames in the gas-entered passageway of described gas turbine generator group, and described second level filter and described third level filter are separately positioned on described filter frame.Air filter also comprises embedded part, and filter frame described in each is fixedly installed in the gas-entered passageway of described gas turbine generator group by described embedded part.Described in each, the periphery of filter frame is provided with mounting hole, and described filter frame is fixedly mounted in the gas-entered passageway of gas turbine generator group by described mounting hole and described embedded part.Described in each, filter frame is provided with square hole, and described in each, the periphery of square hole is provided with a unit frame, and described second level filter or described third level filter operable are arranged on corresponding described unit frame.The periphery of second level filter and third level filter and the periphery of described unit frame leave gap, and described gap is sealed by filter seal pad.Filter frame described in each is provided with some fastening pieces, fastening piece comprises pressing plate and the screw of band through hole, described pressing plate backstop is in the periphery edge place of the described third level filter of the described second level filter of correspondence or correspondence, and screw to be crossed described second level filter or described third level filter backstop after the through hole of described pressing plate in unit frame.Third level filter is bag filter; First order filter is venetian blind inertial filter, and second level filter is folded metal filtration web filter.
But for haze, catkin weather, as added one low efficient filter, although filtered out the large particle thing in air by low efficient filter, Long-Time Service is slightly imitated filtration and is caused gas handling system crushing to increase, and can affect combustion engine efficiency equally; If want dismounting low efficient filter, can spend again manually many, and be difficult to judge air quality in advance.
Simultaneously existing automatically cleaning filtrating equipment, there is cartridge filter cost high, when jetting, dust easily causes secondary pollution, and explosion sound when jetting is large, to environment.
Therefore, need to design a kind of air filter that can decide opening and closing low efficient filter according to weather and deal with the haze weather occurred at any time, need to design a kind of filter area large, the life-span is long, the self-cleaning filter that cost is low simultaneously.
Summary of the invention
The present invention causes gas handling system crushing to increase the problem of combustion engine efficiency of affecting in order to existing filtrating equipment Long-Time Service low efficient filter, solve simultaneously existing self-cleaning filter exist filter area little, the life-span is short, easily cause the problem of secondary pollution, and a kind of blade-rotation air filter for gas turbine is provided, opening and closing low efficient filter can be decided according to weather, thus solve the impact not using low efficient filter on automatically cleaning filter core, avoid the impact of Long-Time Service low efficient filter on gas handling system crushing simultaneously; Filter area and the working life of self-cleaning filter can be improved simultaneously, prevent secondary pollution, meet the requirement of economy of power plant and environment.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
