Abstract
The utility model relates to a riser waste heat recoverer comprising an air injection inlet (1), a hot medium inlet (2), a heat exchanger inner wall (3), a cold medium heat exchange passage (4), a heat exchanger cold medium passage outer wall (5), an outer cylinder (6), a heat exchanger outer wall heat-insulating coat (7), an after-heat-exchange cold medium yielded water distributer (8), an after-heat-exchange cold medium outlet (9), a hot medium outlet (10) and a cold medium inlet (11). The riser waste heat recoverer is characterized in that riser flue gas of a coke oven enters from the hot medium inlet (2) to exchange cold and hot with desalted water entering from the cold medium inlet (11) by virtue of the cold medium heat exchange passage (4) and the heat exchanger inner wall (3), enters into the after-heat-exchange cold medium yielded water distributer (8) and then is output from the cold medium outlet (9), so that after the heat of crude gas of the coke oven is recovered, and by virtue of heat exchange with the desalted water, a steam-water mixture enters a steam header to generate steam by virtue of steam-water separation for use, and therefore a lot of standard coals are saved.
Description
Technical field
The utility model relates to interchanger professional domain, refers in particular to a kind of aqueous vapor interchanger, is a kind of upcast waste-heat recoverer specifically.
Background technology
At present, coal oven dithio-gas sensible heat accounts for 31%～37% left and right of the heat expenditure of whole coke oven, medial temperature is in 700 degree left and right, so far there is not the recycle device of mature and reliable to put into operation, many coal chemical enterprises were both at home and abroad done many experimental studies to pick up the heat more than coke oven ascending tube crude-gas, also have many units once to carry out technological transformation and application, but the processing of the bad working environments while stopping for the processing of high temperature and startup and inner attached long-pending tar and coke disposal are used not satisfactory.
Summary of the invention
The utility model relates to interchanger professional technique, by traditional interchanger principle and technology, in conjunction with the requirement of actual needs and real operating mode, invent and transform, invented this kind of upcast waste-heat recoverer, make full use of flowing of flue gas, enter and carry out heat exchange with de-mineralized water in interchanger, by the design of custom design and unique construction, both guaranteed heat transfer effect, guaranteed again under bad working environments the safety and economic operation of coke oven for iron and interchanger simultaneously.Thereby reclaimed after the heat of coal oven dithio-gas, through the heat exchange with de-mineralized water, processed, steam water interface enters after drum produces steam by carbonated drink is separated and uses, and has saved a large amount of mark coals.
The utility model solves the problems of the technologies described above the following technical scheme of employing:
Upcast waste-heat recoverer, comprise air spray entrance (1), hot media import (2), interchanger inwall (3), refrigerant body heat exchanger channels (4), interchanger refrigerant body channel outer wall (5), urceolus (6), interchanger outer wall heat insulating coat (7), after heat exchange, refrigerant body goes out water distribution (8), refrigerant body outlet (9) after heat exchange, hot media outlet (10), cold Media Entrance (11), it is characterized in that: coke oven coke oven uprising tube flue gas enters from hot media import (2), with the de-mineralized water entering from cold Media Entrance (11), by refrigerant body heat exchanger channels (4), through interchanger inwall (3), carry out cold and hot exchange, after entering heat exchange, refrigerant body goes out water distribution (8) by refrigerant body outlet (9) output after heat exchange.
Preferably, interchanger outer wall heat insulating coat (7) is by above spraying thermal insulation paint at interchanger refrigerant body channel outer wall (5).
Preferably, air spray entrance (1) pressurized air after interchanger inwall (3) coking and knot carbon and tar sprays into by air spray entrance (1).
The beneficial effects of the utility model are:
1, the actual finned and plate-type heat exchanger that is similar to normal operation of this interchanger, only by it by the flat drum type brake that changes into.In interchanger, be provided with the refrigerant body pipeline of multiple pattern, hot media is to adopt only one piping arrangement, and the entrance end of hot media is set at the two ends of interchanger.
2, this interchanger is being provided with the entrance end of refrigerant body and is carrying out special diversion Design near hot media import and export two ends, object is to be uniformly distributed into water and water outlet, thereby the refrigerant body Inlet and outlet water that has guaranteed interchanger keeps constant, there will not be bias current and cause heat exchange non-uniform phenomenon.
3, this interchanger internal layer (instant heating media channel layer) is provided with the material that one deck is high temperature resistant and heat conductivility is stronger (refractory ceramics), and its effect is the high temperature corrosion that prevents flue gas heat exchanger, has guaranteed the good of heat transfer effect simultaneously.
4, this interchanger is provided with the splendid heat insulating coat of effect of heat insulation; at the outside of the cold media channel of interchanger spraying one deck heat insulating coat; its role is to inner heat to be unlikely to spread to rapidly outside; on the one hand outside temperature is effectively reduced; protection of the environment; make on the other hand heat not outer loose, guarantee inner cold and hot media sufficient heat exchange.
5, this interchanger is provided with two nozzles at the entrance end of hot media, when interchanger inwall due to long-time running tarry matters in smoke and coke attached long-pending, while affecting the function of exchange of hot media flow and heat transfer device of interchanger, by nozzle, be pressed into high-pressure air, in interchanger inside, carry out sharply whirlpool shape burning, thereby remove attached long-pending tar and coke, guaranteed the unimpeded and heat transfer effect of interchanger inside.
