Airtight case water cooling plant of blast furnace

The utility model provides an airtight case water cooling plant of blast furnace, belongs to blast furnace top bell -less charging equipment water cooling technology field. Including airtight case, supply channel, return water ring canal, return water closed tube, gaseous closed tube, gas - water separation jar and return water pipeline, the supply channel links to each other with airtight case water inlet, and the return water ring canal is continuous with airtight case delivery port, and it is associative that return water ring canal and gas - water separation jar pass through the return water closed tube, the gas medium's of basin department the mutual UNICOM of mouth passing through gases closed tube difference of external UNICOM about return water ring canal, gas - water separation jar and the airtight case, and the return water pipeline is continuous with gas - water separation jar delivery port. The advantage lies in, installs to device simple structure, the compactness of opening a way, and consumptio
