A kind of solar energy multi-purpose water heater
The utility model relates to a kind of solar energy multi-purpose water heater, not only can produce hot water but also can handle and can obtain clean distilled water former water.
The sixties in last century just the someone attempt developing this solar energy multi-purpose water heater as heat collecting element with flat plate collector, the nineties attempt later on vacuum heat collection pipe as heat collecting element.Because sunshine is evenly sparsely to be radiated at body surface,, flat plate collector and present existing vacuum heat collection pipe be heated to the required temperature more than 100 ℃ of generation steam so being difficult to Jiang Yuanshui.If concentrator is placed at the back side outside vacuum heat collection pipe, because easy dust stratification dirt makes the very fast decline of light gathering efficiency of concentrator, so this solar energy multi-purpose water heater can not applied so far.
The purpose of this utility model provides the solar energy multi-purpose water heater that a kind of novel interior optically focused complete glass vacuum sun thermal-collecting tube is formed, the sunlight intensity that endothermic tube absorbed in its thermal-collecting tube is 3 times of conventional vacuum thermal-collecting tube, and this solar energy multi-purpose water heater has multiple advantages such as thermal capacity is little, temperature rise is fast, running temperature is high, the daily output quantity of steam is many.
The technical solution of the utility model is: adopt some interior optically focused complete glass vacuum sun thermal-collecting tubes, it is characterized in that in vacuum layer endothermic tube below placed the hyperboloid solar panel.The endothermic tube outer surface scribbles coating for selective absorption, inserts metallic water pipe or metal heat-conducting heat pipe in the endothermic tube.The upper end of metallic water pipe or metal heat-conducting heat pipe is inserted steam generator, and steam (vapor) outlet is connected to attemperater by jet chimney.When steam was by coil pipe in attemperater, the water outer with coil pipe had carried out heat exchange.Steam is cooled to distilled water, and the water that has heated simultaneously in the attemperater supplies to have a bath usefulness.
Below in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of interior optically focused complete glass vacuum sun thermal-collecting tube.
The utility model as shown in Figure 1 and Figure 2 comprises cover glass tube 4, endothermic tube 3, metal tube 2, steam generator 5, jet chimney 6, support 7, attemperater 8, coil pipe 9, distilled water outlet pipe 10 and the hyperboloid solar panel 11 of interior optically focused complete glass vacuum sun thermal-collecting tube 1, thermal-collecting tube.(concave surface of hyperboloid solar panel is made minute surface)
S1, S2 represent that the sunray of different directions penetrates on hyperboloid solar panel 11, and the surface that sunshine all reflexes to endothermic tube 3 is absorbed to transfer heat energy to and conduct heat gives metal tube 2.One end closure of metal tube 2, other end opening, openend inserts steam generator 5.Metal tube 2 also can be that two ends are shut, and injects the metal heat-conducting heat pipe of special liquid in the pipe.The wall temperature of metal tube 2 rises and conducts heat to the former water in the pipe, and water temperature rises to and just produces steam more than 100 ℃.Steam enters attemperater 8 through jet chimney 6, and steam is during by the coil pipe 9 in the attemperater 8, and the water outer with coil pipe 9 has carried out heat exchange, and steam is cooled to distilled water, has heated water in the attemperater 8 simultaneously for having a bath usefulness.Distilled water flows out and is collected through distilled water outlet pipe 10.
