Further, also include cooling system: by arranging cooling water pipe at gas filter outer wall, in cooling water pipe, supplement cooling water carry out cooling process.
Further, oil system is also included: provide lubricating oil for the intrasystem equipment of gas turbine inlet air.
Further, filter element is column construction or the square structure of hollow, and the sidewall of filter element is set to sandwich.
Further, the sidewall of filter element adopts steel wire to make, and steel wire has been sticked cloth.
The preferred kapok of described cloth, nylon；The setting of steel wire can strengthen the structural stability of filter element.
Further, inlet channel is at least provided with 2, and adjacent inlet channel is separated by dividing plate.
Further, inlet end place in closed shell inherence is provided with drainage screen.
The large particulate matter of combustion gas inlet side can be carried out intercepting filtration by drainage screen, it is to avoid large particulate matter blocking filter element.
Further, the inlet end of closed shell is provided with joint I, and the beginning of filter element is provided with joint II.
Joint I, joint II are for being connected defecator with other associated devices.
Further, the beginning of filter element is connected to funnel structure, and the interior of funnel structure is gradually increased to outlet side with filter element link without leave, and described joint II is connected with funnel structure.
Arranging of funnel structure can have the exhaust velocity increasing filter element, increases the pressure reduction in outside in filter element further, improves filter efficiency.
To sum up, the beneficial effects of the utility model are:
This utility model has the filter element of sandwich by arranging, it is provided with for absorbing the calcium oxide of moisture and sour gas in combustion gas in sandwich, in filter element, outside forms pressure reduction, make combustion gas by penetrating into inside filter element outside filter element, realizing the filtration to combustion gas, the combustion gas after filtration was discharged by the beginning of filter element, this utility model simple in construction, so, this utility model overcomes the problem that the filter apparatus configuration in existing gas turbine inlet air system is loaded down with trivial details.
