Brief description of the drawings
Fig. 1 is the pipe clamp structure of existing groove type solar thermal-collecting tube support.
Fig. 2 is the pipe clamp insulation construction of novel slot solar energy heating pipe holder of the present utility model.
Detailed description of the invention
The at present conventional insulation material alumina silicate of power plant's industry, calcium silicates, rock wools etc., easily quality deliquescing in the time that temperature is high, has the not enough or shortcoming of satisfied temperature requirement not of compression strength in existing pipe clamp inside as used.
2 conditions below the material require that does heat-insulation and heat-preservation between pipe clamp and steel pipe meets: 1, can be retention under continuous high temperature (the deep fat operating temperature in thermal-collecting tube is 300-400 DEG C); 2, there is very high compression strength (>1 MPa), under the pressure of thermal-collecting tube, can not deform, once deform, steel pipe will depart from the focus place of parabola reflective mirror, and therefore the thermal-collecting tube of groove type solar photovoltaic field requires very high to installation accuracy.
In order to meet the actual requirement of above-mentioned compression strength and temperature, the utility model increases and has high non-deformability and resistant to elevated temperatures insulation construction on the basis of existing groove type solar thermal-collecting tube structure.
As shown in Figure 2, novel slot solar energy heating tubular construction comprises thermal-collecting tube 1 and the support 3 for fixed set heat pipe, and thermal-collecting tube 1 is arranged on support 3 by pipe clamp 2, and above-mentioned thermal-collecting tube 1, support 3, pipe clamp 2 materials all adopt iron and steel.In thermal-collecting tube 1, be mobile conduction oil, temperature is about 300-400 DEG C, and the heat energy of collection is transferred to other equipment application.
Of the present utility model focusing on, in the middle of thermal-collecting tube 1 and pipe clamp 2, insulation construction 4 is set, the concrete precast block of the accurate in size fireproofing and heat resistant of material selection of this insulation construction 4, concrete has good heat insulation and preservation effect, concrete is placed between the thermal-collecting tube 1 and pipe clamp 2 of iron and steel material quality, thermal-collecting tube is not directly contacted with pipe clamp, and heat can not arrive iron and steel pipe clamp and the iron and steel support that the capacity of heat transmission is strong, can effectively avoid the thermal loss of thermal-collecting tube 1.
