Abstract
The utility model relates to a cold quick -witted waste heat recovery device of ring, including the cold machine of ring, the petticoat pipe, the platform truck, the sealing system, the cold quick -witted upper portion flue gas pipeline of ring, exhaust -heat boiler, circulating fan, circular flue, the air -blower, the cold machine in its zhonghuan, the petticoat pipe, platform truck and sealing system constitute ring leng yi district and ring lenger district, ring leng yi district and ring lenger district upper portion flue gas pipeline connect exhaust -heat boiler, the exhaust -heat boiler export is equipped with circulating fan, circulating fan links to each other with circular flue, circular flue is connected to the bellows of a cold -zone platform truck lower part, the last circulating fan export electric butterfly valve that is equipped with of circular flue, blower connection is to the bellows of a cold -zone platform truck lower part, be equipped with electric butterfly valve on the air -blower flue, be linked together between air -blower flue and the circular flue. The utility model discloses simple structure, the small investment makes the little pressure boost of the cold built -in portion of ring, has reduced that sealed cold air gets into between cold quick -witted petticoat pipe of ring and platform truck, effective cold quick -witted waste heat recovery output of ring that improves, the 25-27th that has made flue gas increase in production.
Description
Technical field
The utility model relates to central cooler heat recovery technology field, particularly a kind of central cooler waste-heat recovery device.
Background technology
In central cooler Transforming Engineering, central cooler one cold-zone arranges two collection conduit, and two cold-zones arrange a collection conduit, all configure electronic isolation butterfly valve.During normal work, this valve is opened; Carry out dedusting after two pipelines of one cold-zone are merged into a pipeline, the flue gas collected after dedusting sends into the high-temperature flue gas import of boiler by flue; The flue gas of a pipeline collection of two cold-zones sends into the low-temperature flue gas import of boiler by flue.Boiler export about 140 DEG C flue gases, send into cycle flue by circulating fan, are connected to the bellows of a chassis bottom, cold-zone, recycle.Due to the central cooler waste-heat recovery device newly increased, the flue gas recirculation that boiler reclaims utilizes, and eliminates three air blasts of original chassis bottom.In the process that central cooler waste-heat recovery device uses, the flue-gas temperature reclaimed by boiler is low, flow is little, central cooler inside is made to form negative pressure after being connected to central cooler, outside cold air enters central cooler inside by the sealing ring between ring cold machine smoke hood and chassis, central cooler internal temperature is reduced, decreases the yield of flue gas.Therefore a kind of residual neat recovering system effectively improving central cooler waste heat recovery output is needed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of central cooler waste-heat recovery device, effectively improves central cooler waste heat recovery output.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of central cooler waste-heat recovery device, comprise central cooler, petticoat pipe, chassis, sealing system, central cooler upper smoke feed channel, waste heat boiler, circulating fan, cycle flue, air blast, wherein central cooler, petticoat pipe, chassis and sealing system form Huan Leng mono-district and Huan Leng bis-district, Huan Leng mono-district is connected waste heat boiler with Huan Leng bis-district upper smoke feed channel, heat boiler outlet is provided with circulating fan, circulating fan is connected with cycle flue, cycle flue is connected to the bellows of a chassis bottom, cold-zone, cycle flue is provided with circulating fan outlet electric butterfly valve, air blast is connected to the bellows of a chassis bottom, cold-zone, air blast flue is provided with electric butterfly valve, air blast flue is connected with between cycle flue.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, small investment, makes the inner micro-supercharging of central cooler, decreases the cold air sealed between ring cold machine smoke hood and chassis and enter, effectively improve central cooler waste heat recovery output, make flue gas output increased 25 ~ 27t/h.
