Connection hot-tub at the top of device, and hot-tub connection water pump;The water pump connects drum.
Preferably, the hot-tub and the drum are in the same horizontal position.
Preferably, the heating pipe is fixed on outside the heat exchanger in the shape of a spiral, and heats pipe both ends and heat exchanger
Inside is interconnected.
Preferably, it is homogeneous intercommunicated between the filter screen and the exhaust air chamber, the liquefaction air chamber.
Preferably, connected between the heat carrier and the heat exchanger for anchor ear.
The beneficial effects of the utility model are:This kind of waste heat of coke oven crude gas retracting device is provided with hot water circuit flow, very
The good raw coke oven gas that make use of has thermal energy, avoids thermal waste, and carried out at good cooling to raw coke oven gas
Reason, while hot-tub can accumulate the hot water in heating pipe, there is provided an easy hot-water heating system, hot water is in drum at gasification
After reason, heating system can also be provided;Force (forcing) pump can give the raw coke oven gas flowed out out of coal gas primary cooler to carry out pressurized liquefied processing,
It is different from the liquefied value of other waste gas using coal gas, coal gas and waste gas are efficiently separated, not only realize the recovery profit of coal gas
With being also convenient for the processing of waste gas, be adapted to promote the use of in coking industry technological process.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-2, a kind of waste heat of coke oven crude gas retracting device, including coal stove 1, rise heat exchanger tube 3 and
Force (forcing) pump 5, the bottom of coal stove 1 is provided with bearing 2, and the connection of the top of coal stove 1 rises heat exchanger tube 3;Inside the rising heat exchanger tube 3
Provided with exhaust inner cylinder 13, and it is vented inner cylinder 13 and connects heat carrier 14;The heat carrier 14 connects heat exchanger 15, and outside heat exchanger 15
Portion is provided with heating pipe 16;The outside of heating pipe 16 sets heat-insulated outer barrel 17;The rising heat exchanger tube 3 connects coal gas primary cooler 4,
