Abstract
The utility model relates to an efficient non-scaling solar water heater, comprising a heat storage water tank and vacuum glass heat collecting pipes. The vacuum glass heat collecting pipes are straightly through; the upper ends of the vacuum glass heat collecting pipes are communicated with the heat storage water tank; the lower ends of the vacuum glass heat collecting pipes are communicated with a lower water tank; the bottom of the lower water tank is provided with a cold water inlet and a sewage outlet I; the lower part of the heat storage water tank is provided with a hot water outlet and a sewage outlet II. As the vacuum glass heat collecting pipes are straightly through, the smooth inner walls of the pipes cannot accumulate precipitate or adsorb hard scale, and even if traces of loose adsorbed matter exists on the smooth inner walls of the pipes, the adsorbed matter can fall off in the process of heat exchange caused by absorbing solar energy and under the impact and vibration caused during the water supplement of the lower water tank, can be precipitated into the lower water tank through lower outlets of the vacuum pipes and discharged through the sewage outlets. Therefore, the water heater preserves the prior performances of absorbing and conducting heat and greatly improves thermal efficiency.
Description
Technical field
The utility model relates to a kind of helioplant, particularly a kind of efficient non-scaling solar water heater that utilizes glass tube with vacuum to make the daylighting heat collector.
Background technology
Since the daylighting heat collector that utilizes glass tube with vacuum as solar water heater, always be that a sealing with double-layer glass tube is used for water, absorbing solar energy makes the cold water in water heating and the storage tank produce heat exchange, and make water in water tank obtain heating, its shortcoming is: the one, and there are a large amount of hot water can't get out in the glass tube with vacuum to be not used and waste, having nearly in the 20 arm solar water organ pipes as 146 liters of φ 58 * 1800,65 liters hot water is not used.The 2nd, owing to the vacuum glass inside pipe wall adsorbs a large amount of incrustation scales heat conductivility is descended, the thermal efficiency reduces year by year, as: some hard water matter area solar water heater uses and just stockpiled 1/4 incrustation scale in 2 years.The 3rd, inconvenient blowdown scale removal, influence water quality,, suitable for readingly directly be inserted in the heat storage water tank because glass tube with vacuum bottom seals, want to clear up dirt, must there be the specialized maintenance personnel that glass tube with vacuum is extracted from water tank, refill after outwelling dirt, in this process, the careless slightly glass tube and hurting sb.'s feelings of will damaging, and each cleaning must be again the new sealing ring of transducer set more, time-consuming, take a lot of work, take material, and influence use on the same day.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, proposed a kind of can be with the efficient non-scaling solar water heaters all that utilize, that increase water quality of the hot water in the glass tube with vacuum.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of efficient non-scaling solar water heater, comprise heat storage water tank and vacuum glass heat collection tube, be characterized in: described vacuum glass heat collection tube leads directly to, its upper port is communicated with heat storage water tank, the lower port of vacuum glass heat collection tube is communicated with a lower header, and the bottom of lower header is provided with cooling water inlet and sewage draining exit I, and the bottom of heat storage water tank is provided with hot water outlet and sewage draining exit II.
The technical problems to be solved in the utility model can also come further to realize the same shell, heat-insulation layer and the inner bag of being provided with heat storage water tank of lower header by the following technical programs.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, is provided with fixedly pipe clamp between vacuum glass heat collection tube and the lower header.
The utility model compared with prior art because heat storage water tank leads directly to the glass tube with vacuum that lower header is connected, after the water in the heat storage water tank uses up, is replenishing in the cold water process to lower header, and the hot water in the pipe is headed into to be continued in the heat storage water tank to use; Because vacuum glass heat collection tube leads directly to, smooth inside pipe wall does not have sediment and exists, can not adsorb the hard incrustation scale yet, it is exactly the loose adsorbate of some trace, also can produce in the process of heat exchange absorbing solar energy and shock and vibration that when the lower header moisturizing, produced and coming off, following outlet by vacuum tube is deposited in the lower header, drain by sewage draining exit, also can produce secondary precipitation in heat storage water tank if also have part to rise in the heat storage water tank, discharge by sewage draining exit to heat storage water tank and lower header because of static; Zhi Tong vacuum glass heat collection tube inwall is because cleaning has dirt to exist up and down, improved the thermal efficiency greatly so kept original heat absorption, heat conductivility.
