Abstract
The present invention a kind ofly can make full use of solar radiation, the heat-pipe vacuum-tube boiler that the thermal efficiency is high.Heat pipe and vacuum tube suit are got up, and it is low and stable inadequately to adopt the new working medium of preparing to solve general working medium operating temperature, the defective that thermal capacitance is relatively poor.Can be low to moderate under-100 ℃ the environmental condition and producing boiling water, can not freeze can not burst.Efficiently solve and utilize the whole year solar energy to obtain the problem of boiling water.
Description
The invention belongs to the Application of Solar Energy field.
Utilize solar energy heating to produce boiling water, generally adopt the ordinary vacuum tube heat collector to install paraboloidal reflector additional and make, but that the heated body surface is heated is inhomogeneous, efficient is lower, and cost is higher, and can not tolerate freezing.The heat-pipe vacuum-tube boiler of a new generation in the external test, because: used low boiling working fluid generally is that to adopt acetone, ether, alcohol or pure water etc. to exist operating temperature lower and stable inadequately in (1) heat pipe, and its thermal capacitance is relatively poor, water then should freeze etc.Situation is not satisfactory; (2) heat-pipe vacuum-tube adopts typical white plane sheet reflector, can only reflect diffused light, so efficient is still lower.
The object of the present invention is to provide and a kind ofly make full use of solar irradiation, thermal efficiency height, can be low to moderate under-100 ℃ the condition and produce boiling water, the solar heat-pipe vacuum tube water-boiling device that can not freeze, can not burst.
Realize that technical scheme of the present invention is to prepare a kind of new azeotropic material as the low boiling working fluid in the heat pipe, working medium is by pentane (C
5H
12) accounting for 98.6%～100%, water accounts for 1.4%～0 azeotropic material that synthesizes, and its boiling point is 34.8 ℃～36.1 ℃, and freezing point is-120 ℃～-131 ℃.Its boiling point, freezing point, specific heat, thermal capacitance are all more satisfactory, make the craftmanship excellence of heat pipe in vacuum sleeve.In addition, install the reflector with plane right-angle focussing of another patent applied for of an inventor additional at the heat-pipe vacuum-tube back side, 1.3 times of single tubes when making the theoretical value of incident solar energy by present employing white plane sheet reflector are accepted energy and are risen to when adopting reflector with plane right-angle focussing 4.0 times, the incident solar energy improves about three times, thereby has improved the thermal efficiency of heat-pipe vacuum-tube boiler significantly.
The present invention is mainly by heat-pipe vacuum-tube, and heat exchanger and plane right-angle focussing reflector are formed, and other also has hot water storage tank and connecting rack, framework etc.
Now doing one with regard to it in conjunction with the accompanying drawings describes in detail:
Sunlight shines on the outer wall of metal heat pipe (2) by glass tube (1), because the heat insulating function in glass tube vacuum chamber (9), the metal pipe-wall temperature is more and more higher, and the low boiling working fluid (6) in the pipe absorbs tube wall immediately when temperature is increased to 34.8 ℃ heat of vaporization becomes steam.The other end of heat pipe is the heat exchange end, containing cold water (7) in the heat exchanger (3) is entered by water inlet (10), it is cold in this chance to enter the steam that the low boiling working fluid (6) of heat exchange end flashes to, discharge entrained heat immediately in cold water (7) and condense into liquid, under the hollow billet graviational interaction of liquid capillary medium under the gravity effect or in the pipe, get back to heating end.Again carry out repeatedly evaporation-a condensation process of a new round, liberated heat heats up the cold water in the heat exchanger gradually successively, when reaching boiling point, constant temperature delivery water valve (4) is promptly open automatically because of thermal expansion, boiling water flows in the hot water storage tank (5), running water is pressed in the heat exchanger (3) voluntarily because of pressure own simultaneously.When the cold water water surface that injects arrives constant temperature delivery water valve (4), close automatically because of cold contraction again.Reheat the cold water in the interchanger (3) again.
Accompanying drawing two is the embodiment schematic diagram, is made up of 4 heat-pipe vacuum-tube boilers.In order to improve the thermal efficiency of boiler, strengthen the radiation of sunlight opposite heat tube, to produce more boiling water.Present embodiment adds at the opaco of heat-pipe vacuum-tube (1) puts reflector with plane right-angle focussing (2), make impinge upon on the heat-pipe vacuum-tube sunlight by just, side, the several aspects of the back of the body penetrate, thereby greatly improved the thermal efficiency of heat-pipe vacuum-tube.Even also can obtain boiling water under the weather conditions in severe winter.
In mid latitudes (for example in the area, Lanzhou), every square metre section rice and flour amassed and can produce boiling water 40-50Kg every day in summer.Every square metre of optical cross section was amassed and can be produced boiling water 10-15Kg every day in winter, and never burst summer, and winter is never icing.Have good anti-high and cold performance, can under-100 ℃ harsh climate condition, use.Solved the annual problem of utilizing solar energy to obtain boiling water effectively.
