Technical field
The utility model relates to a kind of gas turbine air processor, is specifically related to a kind of air filter dust-removing device.
Background technique
Gas turbine is for generator provides the device of mechanical energy by burning combustible gas.Need before gas fuel burning with air mixing to ensure Thorough combustion, so gas turbine has two gas inlets, one is combustible gas inlet, and another is air intlet.Inflammable gas is generally upstream producer or workshop section provides, it is totally treated, air is for directly aloft to obtain, if dust wherein enters gas turbine and can damage impacting property of blade, the surge even caused, affect generator set performance and safe operation, need to install air filter additional before the air inlet of therefore gas turbine.
The air filter of existing gas turbine mainly comprises cartridge filter and successively along first, second, and third filter layer that the path radial direction that air enters is arranged, the first filter layer is fibre felt layer, and the second filter layer is layer of polyester fiber, and the 3rd filter layer is filter paper layer.First filter layer contacts with air at first, so the impurity of large volume filtered is more, but fibre felt layer once with impurity phase mutual connection after touch, the adsorptivity on fibre felt layer surface is comparatively strong, can tightly by impurity absorption, so cleaning bothers very much, waste time and energy.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, user cost is low and the gas turbine air filter of good filtration effect.
To achieve these goals, the utility model provides a kind of gas turbine air filter, comprise cylindrical housings, be arranged on the suction port above housing, a conical filter net is provided with in described housing, the vertex of a cone of conical filter net is towards suction port, conical filter net is axially arranged with a rotating shaft be fixedly connected with the vertex of a cone, edge and the inner walls spacing of conical filter net are not more than 5mm, conical filter side off the net is provided with the cylindrical filter sieve coaxial with it, the two ends up and down of this cylindrical filter sieve form air collecting chamber by ring seal plate and housing, the outer wall of described air collecting chamber is provided with air outlet, spirality hairbrush rotating shaft being fixed with rotation blade and connecting with cylindrical filter sieve inwall, the bottom of described housing is provided with an impurity discharging port, this impurity discharging port is positioned on the surface of revolution of spirality hairbrush.
The feature of technique scheme is: owing to have employed the form of dynamically cleaning, namely after air enters from suction port, first carry out first time through conical filter net to filter, then rotation blade is blown, rotation blade drives axis of rotation, rotating shaft drives conical filter net and spirality hairbrush to rotate, then air enters cylindrical filter sieve, and carry out secondary filter through cylindrical filter sieve, spirality hairbrush sideway swivel in cylindrical filter sieve simultaneously, the dust on continuous cleaning surface, dust is discharged together with the impurity discharging port of partial air from housing bottom, overall structure is fairly simple, because cylindrical filter sieve can be cleaned automatically, so user cost is lower, simultaneously due to the accumulation of dust can not be produced, therefore filtering effect also can be maintained, must progressively be deteriorated.
Preferably, the top of described conical filter net is provided with a broad wool brush connected with its sidewall, broad wool brush is fixed in inner walls by rod member, the housing of conical filter network edge is provided with relief opening, arranging like this can make conical filter net constantly contact with broad wool brush in the process rotated, get rid of the impurity of conical filter net surface in time, impurity is drained from relief opening with partial air, thus keeps the filtering effect of conical filter net.
Preferably, the interior diapire of described housing is obliquely installed, and described impurity discharging port is positioned at the extreme lower position of diapire, and such arranging can make impurity discharging port more easily collect dust impurity, thus plays better impurities removal effect.
Preferably, the aperture of described conical filter net is 60 ~ 70 orders, and the aperture of cylindrical filter sieve is 100 ~ 115 orders, and such arranging can ensure that namely the air filtered out meets the requirement of gas turbine, can save again the energy consumption of filtration simultaneously.
Preferably, described conical filter sieve bottom connects with annular seal plate, and such arranging can avoid air causing large-amplitude sloshing through conical filter net, thus filtering effect is better.
Preferably, the pitch of described spirality hairbrush equals the height of cylindrical filter sieve, and such arranging is passable.
