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 equipment in gas handling system。
Further, filter element is column construction or the square structure of hollow, and the sidewall of filter element is set to sandwich。
Further, the outlet side of closed shell is provided with the fixing seat of filter element, and the blind end of filter element is connected with the fixing seat of filter element；The fixing seat of described filter element is connected by dividing plate with closed shell。
Improve the structural stability of filter element, it is to avoid the problem that filter element in use rocks。
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, outlet passageway, at least provided with 2, is separated by dividing plate between adjacent outlet passageway。
Further, it is provided with drainage screen in air induction conduit。
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 air induction conduit is provided with joint I, and the outlet side of enclosed housing is provided with joint II。
Joint I, joint II are for being connected defecator with other associated devices。
Further, the inwall of filter element is set to wavy shaped configuration。
Wavy shaped configuration can effectively increase filter area, improves filter effect。
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging the filter element with sandwich, in sandwich, it is arranged to absorb the calcium oxide of moisture and sour gas in combustion gas, in filter element, outside forms pressure reduction, make combustion gas by penetrating into inside filter element outside filter element, realize the filtration to combustion gas, combustion gas after filtration was discharged by the beginning of filter element, and present configuration is simple。
What 2, invention adopted is by the internal filter type to outside of filter element, filter element intrinsic pressure much larger than external pressure, it is possible to effectively improved efficiency。
