Embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and principle of work.
As shown in drawings, the water-cooling jacket device of the utility model, it has chuck inside panel (4), the chuck inside panel has water jacket inner core plate (6) outward, water jacket inner core plate has water jacket urceolus plate (5) outward, on water jacket inner core plate, the water jacket urceolus plate hypomere gas outlet tube (3) is installed, there is cyclic top board (8) on chuck inside panel, water jacket inner core plate, water jacket urceolus plate top, and destructive distillation cylindrical shell (1) is arranged above the top board.
There is base plate (7) lower end of water jacket inner core plate.The outside at base plate is stretched out in chuck inside panel bottom.
During installation, the top of the gasification section body of heater of original single hop stove is injected in chuck inside panel bottom, the furnace top cover on original single hop stove is installed on destructive distillation cylindrical shell top.Base plate (7) lower surface contacts with gasification section body of heater upper surface.The hypomere gas outlet tube communicates with gasification section body of heater inner chamber.This transformation, the device of the utility model in the increase on original single hop stove does not just add change to the structure of other parts of single hop stove.Be that stoker and gas outlet tube are housed on the furnace top cover, devices such as grate, ash exhauster and gas blower are arranged at gasification section body of heater bottom.
During use, injecting softening water in the cavity between water jacket inner core plate, water jacket urceolus plate, circulates in softening water and outside.The lump coal that with granularity is 25～50mm is sent in the destructive distillation cylindrical shell by stoker, and the hot flue gas that semicoke gasification in body of heater bottom produces rises through chuck inside panel inner chamber, heats coal cinder in indirect and direct mode, and it is carried out low-temperature pyrolysis.The beginning preheating and drying temperature of coal is about 120 ℃, destructive distillation termination temperature is about 550 ℃.In the esoteric reaction of destructive distillation tube mainly is to carry out finish-drying and destructive distillation to going into stove bituminous coal, becomes hot semicoke behind the arrival chuck inside panel inner chamber.Hot semicoke enters the gasification section body of heater and gasifies.
