In sum, designing a kind of device that the waste heat of cement plant high-temperature furnace body is recycled, is a kind of effective energy saving way.
Utility model content
the technical problems to be solved in the utility model is to provide a kind of waste-heat recovery device for cement plant high-temperature furnace body, can in the situation that not affecting high-temperature furnace body rotation, carry out waste heat recovery, reduces thermal dissipation, reduces the thermal pollution to surrounding environment.
To achieve these goals, technical solution adopted in the utility model is: a kind of waste-heat recovery device for cement plant high-temperature furnace body, comprise the heat collector, reflecting layer and the heat-insulation layer that from inside to outside cover on successively high-temperature furnace body outer surface, the distance between heat collector and high-temperature furnace body outer surface is 130mm ~ 180mm.
As a kind of optimal technical scheme of the present utility model, described heat collector is for being evenly arranged in the U-shaped thermal-collecting tube of described high-temperature furnace body outside, and U-shaped thermal-collecting tube comprises basalis and is laid on the absorber coatings of basalis outer surface.
As a kind of optimal technical scheme of the present utility model, described basalis adopts 316L stainless steel tube, described absorber coatings comprises infrared reflecting layer, high tenor cermet coating, low-metal content cermet coating and the antireflection layer of outwards laying successively from the outer surface of basalis, in U-shaped thermal-collecting tube, have circulating water, the two ends of U-shaped thermal-collecting tube are respectively water inlet and delivery port.
As a kind of optimal technical scheme of the present utility model, the water inlet of described U-shaped thermal-collecting tube is positioned at the below of delivery port.
As a kind of optimal technical scheme of the present utility model, described heat-insulation layer comprises steel pipe I, be enclosed within the steel pipe II of steel pipe I outside and be folded in steel pipe I and steel pipe II between heat insulation layer, described reflecting layer is the silicone coating that is coated on described steel pipe I inner surface.
The beneficial effect that adopts technique scheme to produce is: first the utility model reclaims high-temperature furnace body waste heat around by heat collector, then by reflecting layer by from heat collector gap, shed auxiliary penetrate to reflect continue to be absorbed by the opposite side of heat collector, raising is to the utilization ratio of radiant energy and reduce the thermal deviation of heat collector, increase the service life, finally by heat-insulation layer, completely cut off its inner side and the heat convection of surrounding air scattering and disappearing of reduced radiation heat to a greater degree, final realization carried out waste heat recovery in the situation that not affecting high-temperature furnace body rotation, reduce thermal dissipation, the object of reduction to the thermal pollution of surrounding environment.
