The double-layered hollow spiral heat collector has high heat collection efficiency and structurally comprises an inner heat conduction pipe fitting, an outer heat conduction pipe fitting and a spiral steel strip, wherein the inner side edge of the spiral steel strip is fixedly connected with outer wall of the inner heat conduction pipe fitting, and the outer side edge is fixedly connected with inner wall of the outer heat conduction pipe fitting; the inner heat conduction pipe fitting, the outer heat conduction pipe fitting and the spiral steel strip jointly form a spiral channel; and the heat collector further comprises an insulating layer wrapping the outer wall of the outer heat conduction pipe fitting.
Description
Technical field
The utility model relates to energy-conserving and environment-protective technical field, specifically the heat collector in a kind of waste heat of chimney retracting device.
Background technology
Along with the development of producing, human development and utilized a large amount of non-renewable energy resources.Day by day accelerate in development, the energy is gradually in situation in short supply, and the product of energy-conserving and environment-protective receives people's concern more and more.The enterprise of domestic production at present great majority are still using diesel oil, natural gas, fire coal etc. as main energy sources, and conventional Industrial Boiler, high-temperature tail gas that dining room cooking stove equals to produce in the course of work do not discharge again to utilize, fuel availability is low, causes the serious wasting of resources.Adopting waste heat of chimney retracting device to carry out heat recovery to boiler exhaust gas is more effective power-economizing method at present, and the operating efficiency of waste heat of chimney retracting device depends primarily on heat collector, thereby the collecting efficiency of raising heat collector can effectively improve the operating efficiency of waste heat of chimney retracting device.
Utility model content
The utility model object is, a kind of heat collector of high collection effciency is provided.
The utility model is achieved through the following technical solutions this object:
A kind of double layer hollow spiral collecting device, comprises pipe fitting, heat conduction outer tube member, helical steel band in heat conduction; Pipe fitting outer wall is fixedly linked in described helical steel band inside edge and heat conduction, and outer ledge and heat conduction outer tube member inwall are fixedly linked, the interior pipe fitting of heat conduction, heat conduction outer tube member, the helical steel band helical duct that is jointly shaped; Also comprise the heat-insulation layer that covers heat conduction outer tube member outer wall.
Adopt the waste heat of chimney retracting device of described double layer hollow spiral collecting device to carry out tail gas heat quantity while reclaiming, tail gas flows out in pipe fitting in heat conduction, in heat conduction, pipe fitting absorbs the heat energy of tail gas, and in heat conduction simultaneously, pipe fitting is also passed to heat helical steel band, heat conduction outer tube member; The heat-conducting fluid of waste heat of chimney retracting device, if water or air are in the time that helical duct flows, in heat conduction, pipe fitting, heat conduction outer tube member, helical steel band all heat heat-conducting fluid.
As the improvement of technique scheme, in described heat conduction, pipe fitting, heat conduction outer tube member are steel pipe, and both coaxially arrange.
As the improvement of technique scheme, pipe fitting in described heat conduction, heat conduction outer tube member two ends are concordant.
As the improvement of technique scheme, in described heat conduction, relative heat conduction outer tube member two ends, pipe fitting two ends stretch out.
Prior art relatively, the helical steel band of the utility model double layer hollow spiral collecting device has increased the heat transfer area of heat-conducting fluid and heat collector, its inner helical duct forming increases heat-conducting fluid in the heat transfer time of heat collector simultaneously, thereby this double layer hollow spiral collecting device collecting efficiency is high.In the time that in described heat conduction, pipe fitting, heat conduction outer tube member are steel pipe, this double layer hollow spiral collecting device can also directly use as chimney, and this structure has very strong rigidity, chimney can be extended higher, thereby make its collecting efficiency higher, be also beneficial to the diffusion of flue dust simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of one of them embodiment of the utility model.
Fig. 2 is that in Fig. 1, double layer hollow spiral collecting device is removed the structural representation after heat conduction outer tube member, heat-insulation layer.
Description of symbols: pipe fitting in 1-heat conduction, 2-helical steel band, 3-heat conduction outer tube member, 4-heat-insulation layer.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Figure 1 shows that one of them embodiment of the utility model double layer hollow spiral collecting device.This double layer hollow spiral collecting device comprises pipe fitting 1, heat conduction outer tube member 3, helical steel band 2 in heat conduction; In described helical steel band 2 inside edges and heat conduction, pipe fitting 1 outer wall is fixedly linked, and outer ledge and heat conduction outer tube member 3 inwalls are fixedly linked, pipe fitting 1, heat conduction outer tube member 3, the common shaping helical duct of helical steel band 2 in heat conduction; Also comprise the heat-insulation layer 4 that covers heat conduction outer tube member 3 outer walls.Concrete, in described heat conduction, pipe fitting 1, heat conduction outer tube member 3 are steel pipe, both coaxially arrange and two ends concordant; Certainly in heat conduction, pipe fitting 1, heat conduction outer tube member 3 also can be made up of other metal material, in heat conduction pipe fitting 1 two ends also relatively heat conduction outer tube member 3 stretch out.
Adopt the waste heat of chimney retracting device of described double layer hollow spiral collecting device to carry out tail gas heat quantity while reclaiming, tail gas is circulation in pipe fitting 1 in heat conduction, in heat conduction, pipe fitting 1 absorbs the heat energy of tail gas, and in heat conduction simultaneously, pipe fitting 1 is also passed to heat helical steel band 2, heat conduction outer tube member 3; The heat-conducting fluid of waste heat of chimney retracting device is in the time that helical duct flows, and in heat conduction, pipe fitting 1, heat conduction outer tube member 3, helical steel band 2 all heat heat-conducting fluid; , or utilized by other heat engine, heat-carrying air boiler heat supplying with the heat-conducting fluid after heating, reach energy-conservation object.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
