Description
Technical field
The utility model relates to a kind of cooling device.Specifically, be the cooling device that can carry out strengthening to circulating ash cooling, be particularly useful on the smoke separator of CFBB.
Background technology
All know in boiler for producing industry, the smoke separator of CFBB is mostly provided with circulating ash cooling body, this cooling body is arranged on the cooling body inside separator direct tube section and cone section.This cooling body mainly contains air cooling cooling body and cooling by water mechanism, these two kinds of cooling bodies are all at corresponding separator direct tube section and cone section disposed inboard pipeline, and respectively to cold air logical in pipeline and cold water, utilize the cold air of Bottomhole pressure or cold water to carry out heat exchange to pipeline and the circulating ash touching pipeline is cooled.This cooling body has the following disadvantages, and one is because cooling body is arranged on inside the wall of direct tube section, and volume is large, and the metallic conduit of needs is many, and production cost is high.And difficulty of processing is large, general boiler for producing enterprise processing is more difficult.Two is that a set of cooling body need divide 3 ~ 5 to dispatch from the factory, and assemble to building-site, mounting cost is many, and cost is high because volume is large.Three is because cooling body is arranged on inside the wall of direct tube section, and during boiler operatiopn, first the cooling body of separator direct tube section is subject to the smoke-shock from import, and wearing and tearing, booster fault easily appear in the pipeline in cooling body.Four is that these cooling bodies have blocked circulating ash owing to being provided with cooling body inside separator direct tube section and cone section, the contact area of the circulating ash that separator is separated and separator inwall only have separator total heating surface to amass less than 30%., reduce the utilization rate of separator heating surface area.
Utility model content
Problem to be solved in the utility model is to provide a kind of CFBB circulating ash strengthening cooling device.This cooling device, not only volume is little, consumption metallic conduit is few, be convenient to installation, production cost is low, and avoids pipe wear, booster fault, improves the utilization rate of separator heating surface area.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
CFBB circulating ash strengthening cooling device of the present utility model comprises cylinder, and this cylinder is followed successively by direct tube section, cone section and dipleg section from top to bottom, and described direct tube section, cone section and dipleg section are structure as a whole, and the junction of inner chamber is streamline transition.In direct tube section, suspention has central tube, and the sidewall of direct tube section has import.The strengthening cooling body for cooling circulating ash is all had in described cone section and dipleg section.Be characterized in that described strengthening cooling body comprises the heat-transfer pipe cast in cone section and dipleg section body of wall, cone section and the axis of the heat-transfer pipe in dipleg section body of wall bore section respectively with place parallel with the wall of dipleg section and uniform along the circumferencial direction of boring section and dipleg section.To stretch out after heat-transfer pipe upper end in described cone section is bent outwardly outside the wall of cylinder and to be connected with refrigerant source by pipeline, to stretch out after the heat-transfer pipe upper end in dipleg section is bent outwardly outside the wall of cylinder and to be connected with refrigerant source by pipeline.Described heat-transfer pipe is all connected with the heat-conducting plate passing through heat-transfer pipe overall length near the side of cylinder medial surface, leave spacing between the inside of described heat-conducting plate and cylinder medial surface.
As can be seen from the above scheme, owing to being only provided with strengthening cooling body in cone section or dipleg section body of wall, compared with the direct tube section being arranged on separator with cooling body, volume is little, and the metallic conduit of needs is few, and production cost is low.Because difficulty of processing is little, general boiler for producing enterprise can process.Because volume is little, cooling body can be installed in factory, the whole series are dispatched from the factory, and do not need building-site to assemble, mounting cost is few, and cost is low.Heat-transfer pipe and heat-conducting plate again owing to strengthening cooling body cast in cone section or dipleg section body of wall, avoid that cooling body blocks circulating ash, the contact area of circulating ash that separator is separated and separator inwall increases, thus improve the utilization rate of separator heating surface area.
