Further, the volume of the absorbing liquid is arranged to the half for being no more than spray sump volume.
Further, the top of the fixed frame is fixedly installed two engaging lugs.
Compared with prior art, the beneficial effects of the utility model are:
1. be fixedly installed gas cleaning plant by the side in fixed frame, by spray groove and adsorption tower to can be to useless
Impurity in gas carries out purified treatment, is easy to waste gas directly to discharge, reduces pollution of the waste gas to air, economic and environment-friendly.
2. by setting biological adsorption layer and activated carbon adsorption layer in adsorption tower, so as to the organic impurities energy in waste gas
It is maximized to remove, reach no pollution discharge, be easy to use.
3. by the way that engaging lug is fixedly installed on fixed frame top, so that device is easy to stable connection to use, avoid
It is unexpected to occur.
