Solar water heater is carried the enhancing device of warm water to the pipeline of biogas pool wall
Technical field
The present invention relates to the enhancing device of solar water heater, belong to technical field of new energy application to the pipeline conveying warm water of biogas pool wall.
Background technology
1970-1980; Because the restriction of scientific and technical condition at that time; Living standards of the people are not high, and how Chinese residents repacks the closing-sunning type water heater into empty petrol drum and be placed on the liquid water that tans by the sun under the sunlight in the thermotank, and the method efficient that this dependence sunlight directly shines the liquid water in the heat bucket is low, rapid heat dissipation, solarization hot water amount are little; Because practical value is not high, the closing-sunning type water heater suffers exit already.
Up to 1984, teacher's invention of Tsing-Hua University ' magnetron sputtering gradual change aluminium---nitrogen/aluminium solar selective absorbing coating ' made vacuum pipe solar water heater efficiently utilize solar energy to realize that large-scale production and commercial applications become possibility.The inventor of this patent in 2009, China's invention academician Miao TongChun are participated in the experience exchangement meeting of China invention association and organization to Beijing, hear that at the meeting the teacher of this invention vacuum pipe solar water heater of Tsing-Hua University introduces his painstaking efforts, the speech of having the courage to bring forth new ideas.
In recent years, solar water heater reaches 2.46 hundred million square metres in global erection space, China account for wherein 64%.The solar thermal utilization industry development of China Shandong Province is very fast; The emperor is bright, the water heater year volume of production and marketing of Li Nuoruite and Sang Le three tame enterprises reaches more than 3,700,000, product quality improves year by year; The coating technique of vacuum tube and technology such as vacuumize, seal and update constantly strengthens the vacuum tube ' heart ' of solar water heater.Shine upon the outer tube of vacuum tube, photo-thermal is absorbed the back by the thermal-arrest plated film and transmits the water in the heating tube along tube wall, and the water heat absorption back temperature in the pipe raises, and proportion reduces and rises, and forms a power that makes progress, and constitutes a thermal siphon system.Along with hot water constantly on move and be stored in storage tank top, the lower water of simultaneous temperature makes FCL hot water rise to certain temperature hot water for people to use along the continuous replenishment cycles heating of the opposite side of pipe.Because the technology of solar water heater is quite ripe, result of use is obvious, has received the people's popular welcome.Cities such as Yantai, Shandong Province are in order to build a conservation-minded society; Launched respectively the suggestion of in whole city's dwelling construction, promoting the use of solar water heater and complete set technology; On the roof plane of the high residential building below 12 layers in the building in many cities, solar water heater has been installed generally, to residential building resident hot-water supply.
Chinese countryside has built up big and small 30,000,000 mouthfuls of methane-generating pits; Because the biogas bacterium must fermented in the middle temperature environment about 35 ℃ or in about 55 ℃ the hot environment; Ability is decomposing organic matter effectively; Produce more biogas, and disperse to be built in 30,000,000 mouthfuls of methane-generating pits in the natural environment of rural area, its pond temperature often has the above time of half a year not reach 20 ℃; Had a strong impact on the factor of created gase of methane-generating pit, all parts of the country exist many because the pond temperature is not enough, very few ' morbid state ' methane-generating pit of product biogas.Inventor's Miao TongChun of this patent is crossed the present situation of many seats methane-generating pits to rural survey, never sees the solar water heater that can utilize sunlight to produce hot water is installed at the top of methane-generating pit.At present, solar radiation wastes to the light and heat at methane-generating pit top, does not utilize solar energy optical-thermal to increase the gas production of methane-generating pit through solar water heater.
