Work process of the present utility model: gas enters into filter core inside by air inlet conduit, it is set to close end due to the filter core other end, gas can only enter into filter core outside through the calcium oxide arranged in interlayer structure, owing to the moisture being mixed with in combustion gas and acid gas are absorbed and tackle solid particle by calcium oxide, thus the gas entering into filter core outside is the gas of cleaning, clean gas is discharged by outlet passageway, owing to the space, inside of filter core is much smaller than the space, inside of closed shell, the gas entering into closed shell inside by filter core can spread rapidly and discharge, make the internal pressure of pressure much larger than closed shell of filter core inside, namely the inside and outside side pressure difference of filter core is bigger, improve the filtration effect of filter core, so, it is loaded down with trivial details that the utility model overcomes existing filter apparatus configuration, filter the problem that efficiency is lower.
The utility model has the filter core of interlayer structure by arranging, the calcium oxide for absorbing moisture and acid gas in combustion gas it is provided with in interlayer structure, in filter core, outside forms pressure reduction, make combustion gas by penetrating into inside filter core outside filter core, realize the filtration to combustion gas, combustion gas after filtration was discharged by the beginning of filter core, and the utility model structure is simple; And the utility model adopt be by filter core inside to outside filtration mode, the interior pressure of filter core is much larger than outer pressure, it is possible to effectively improved efficiency.
Further, the outlet side of closed shell is provided with filter core holder, and the closed end of filter core is connected with filter core holder.
Improve the Stability Analysis of Structures of filter core, avoid the problem that filter core in use rocks.
Further, filter core holder is connected by dividing plate with closed shell.
Further, outlet passageway is at least provided with 2, is separated by dividing plate between adjacent outlet passageway.
Further, the inwall of filter core is set to wavy shaped configuration.
Wavy shaped configuration can effectively increase filtration area, it is to increase filters effect.
Further, filter core is column construction or the square structure of hollow, and the sidewall of filter core is set to interlayer structure.
Further, the sidewall of filter core adopts cloth to make.
The preferred kapok of described cloth, nylon.
Further, the sidewall of filter core 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 Stability Analysis of Structures of filter core.
Further, it is provided with screen pack in air inlet conduit.
The large particulate matter of combustion gas inlet side can be carried out interception and filter by screen pack, avoids large particulate matter blocking filter core.
Further, the air inlet end of air inlet conduit is provided with joint I, and the outlet side of enclosed housing is provided with joint II.
Device is connected with other associated devices for filtering for joint I, joint II.
To sum up, the beneficial effects of the utility model are:
1, the filter core that the utility model has interlayer structure by arranging, calcium oxide for absorbing moisture and acid gas in combustion gas is set in interlayer structure, in filter core, outside forms pressure reduction, make combustion gas by penetrating into inside filter core outside filter core, realize the filtration to combustion gas, combustion gas after filtration was discharged by the beginning of filter core, and the utility model structure is simple.
2, practical novel employing is inner to outside filtration mode by filter core, and the interior pressure of filter core is much larger than outer pressure, it is possible to effectively improved efficiency.
