Abstract
The invention belongs to the technical field of gas turbines, discloses an integrated multistage air filtration system, and solves the problems that production, manufacture and maintenance cost are high because the spaces among three stages of filters of a filtering chamber of a conventional gas turbine is too large, and solves the problem that because a conventional filtering system employs a coarse filter for a long time, the pressure loss of an air inlet system is increased, the gas turbine efficiency is influenced and artificial mounting/dismounting cost of a coarse filter is high. 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 is and in particular to a kind of integrated type multi-stage air mistake for air cleaning
Filter system, for carrying out purification filtering to the air inlet of gas turbine.Present invention may also apply to the air cleaning of other field.
Background technology
Gas turbine is the rotary power that a kind of gas using continuous flowing is converted to heat energy as working medium mechanical work
Machinery.In the main flow of air and combustion gas, mainly combustion gas is formed by this three big part of compressor, combustor and combustion gas turbine
Turbine circulates.
Compressor sucks air from ambient atmosphere environment, and compresses step by step through axial-flow compressor and be allowed to be pressurized, simultaneously
Air humidity also accordingly improves；The combustion gas that compressed air is pressed to combustor with the fuel mixture manufacturing High Temperature High Pressure spraying into；
Then enter back into expansion work in turbine, promote turbine drive compressor together with outer load rotor high-speed rotation it is achieved that
The chemical energy of gas and liquid fuel is converted into mechanical energy, and exports electric work.
The inlet air flow of gas turbine blower is that the combustion air of gas turbine must be carried out before being introduced into compressor
Purified treatment.It is most commonly that and above-mentioned air inlet, the corrosive and dirty grain of preventing belt are purified using the fabric filter of machinery
Son enters compressor and turbine, thus preventing corrosion and the breakage of equipment, and reduces cleaning and the workload of maintenance.For producing
The gas turbine of the energy needs substantial amounts of combustion air, therefore, even micro impurity all can lead to produce in use
Raw a large amount of deposits, it requires filtration combustion air as efficiently as possible.
The air draught entering gas turbine is filtered using air filtering system, due to the air requirements of gas turbine
Amount is larger, and therefore filtration system is typically both configured to filter the structure in room, the such as invention of Application No. 201110448766.2
Patent discloses a kind of air filter, first order filter, second level filter and third level filter, and described first
Level filter, described second level filter and the spaced gas turbine generator group that is sequentially arranged in of described third level filter
In inlet channel.Air filter also includes being spaced multiple in the inlet channel being fixed on described gas turbine generator group
Filter frame, described second level filter and described third level filter are separately positioned on described filter frame.Air
Defecator also includes built-in fitting, and each described filter frame is fixedly installed in described combustion gas wheel by described built-in fitting and generates electricity
In the inlet channel of unit.The periphery of each described filter frame is provided with installing hole, and described filter frame is by described peace
Dress hole is fixedly mounted in the inlet channel of gas turbine generator group with described built-in fitting.Each described filter frame is provided with
Square hole, is provided with a unit frame, described second level filter or described third level filter in the periphery of each described square hole
It is operably mounted at corresponding described unit frame.The periphery of second level filter and third level filter and described unit frame
Periphery leave gap, described gap is sealed by filter seal pad.Each described filter frame is provided with some fastenings
Part, securing member includes the pressing plate with through hole and screw, and described pressing plate backstop is in corresponding described second level filter or corresponding
At the periphery edge of described third level filter, by described second level filter or described after the through hole of the excessively described pressing plate of screw
Third level filter backstop is in unit inframe.Third level filter is bag filter；First order filter is shutter inertia
Filter, second level filter is folded metal filtration web filter.
However, the air capacity due to needing when gas turbine works is larger, needs setting individually to filter room and air is entered
Row filters, and the spacing between existing tertiary filter is larger, is equipped with access path and is easy to each between filters at different levels
Filter is checked, which not only adds the area filtering room, increased manufacturing cost, increased staff's inspection simultaneously
The time repaiied, improve maintenance cost.
It is simultaneous for haze, Semen Salicis babylonicae cum piluss weather, such as add one low efficient filter although air is filtered out by low efficient filter
In bulky grain thing, but life-time service slightly imitate filtration lead to gas handling system crushing increase, equally can affect combustion engine efficiency；If
Low efficient filter to be dismounted, can spend many artificial again, and be difficult to judge in advance air quality.
Accordingly, it would be desirable to a kind of air filter that can be determined according to weather to be opened and closed low efficient filter of design is tackling
The haze weather occurring at any time.
Content of the invention
The present invention leads to manufacture and maintenance in order between the filtration room tertiary filter of existing combustion gas wheel, spacing is larger
The problem of high cost, solves existing filtration system life-time service low efficient filter simultaneously and leads to gas handling system crushing to increase impact combustion
Engine efficiency, the problem of the high cost of artificial dismounting low efficient filter, and provide a kind of integrated type multi-stage air filtering system, by three
Level filter carry out integrated, decrease filter room area, thus reduce filter room manufacture cost, decrease work people
The time that member safeguards, reduce the cost safeguarded；Can be determined according to weather to be opened and closed low efficient filter, thus solving not simultaneously
Using the impact to automatically cleaning filter core for the low efficient filter, avoid life-time service low efficient filter to gas handling system pressure simultaneously
The impact damaged.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of integrated type multi-stage air filtering system, filters dress including the thick effect filtering room and be arranged in filtration room
