The integrated multistage air filtration system comprises a filtering chamber, and a coarse filtering device, a medium-efficiency filter and a high-efficiency filter arranged in the filtering chamber; the coarse filtering device comprises a connection rod and multiple vertically-arranged coarse filters, the upper end of the coarse filters are all hinged in the filtering chamber, and the other ends of the coarse filters are all hinged to the same connection rod; and the bottom surface of the coarse filter at the downmost end is hinged to a telescopic cylinder or hydraulic cylinder, and the other end of the cylinder or the hydraulic cylinder is hinged in the filtering chamber.
Description
Technical field
The invention belongs to gas turbine technology field, be specifically related to a kind of integrated type multi-stage air filtering system for air purification, for carrying out purification filtering to the air inlet of gas turbine.The present invention also can be used for the air purification 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.
The air draught entering gas turbine adopts air filtering system to filter, because the air requirements amount of gas turbine is larger, therefore filtration system is generally all set to the structure of filtering room, such as application number be 201110448766.2 patent of invention disclose a kind of air filter, first order 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, because the air quantity needed when gas turbine works is larger, need to arrange independent filtration room to filter air, spacing between existing tertiary filter is larger, be equipped with access path between filter at different levels to be convenient to check each filter, which not only adds the area filtering room, add manufacture cost, add the time of staff's maintenance simultaneously, improve maintenance cost.
Simultaneously 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.
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.
Summary of the invention
Between the filtration room tertiary filter that the present invention takes turns in order to existing combustion gas, spacing causes more greatly the problem manufactured and maintenance cost is high, solve the problem that cost that existing filtration system Long-Time Service low efficient filter causes gas handling system crushing to increase affect combustion engine efficiency, manually dismounting low efficient filter is high simultaneously, and a kind of integrated type multi-stage air filtering system is provided, tertiary filter is carried out integrated, decrease the area filtering room, thus reduce the cost filtering room and manufacture, decrease the time that staff safeguards, reduce the cost safeguarded; Opening and closing low efficient filter can be decided according to weather simultaneously, 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.
