The solar steam generator is used for preparing water steam, during use, water close to the steam outlet end in the vacuum pipe always boils first to generate steam, the steam is generated quickly and continuously with little influence from the weather, the continuously generated steam can be utilized conveniently, and the use ratio of the solar energy is high.
Description
Technical field
The invention belongs to solar energy heat-collecting device technical field, specifically relate to a kind of device that utilizes solar energy to add hot water and obtain steam.
Background technology
The existing solar energy heat collector that uses is mainly adopted heat pipe by heat collection water tank and vacuum and is formed, the heat collection water tank volume is big, and being accumbency at support body is horizontally disposed with, vacuum is adopted heat pipe and is plugged on the heat collection water tank bottom side by side, and each vacuum is adopted the mouth of pipe height of heat pipe substantially on same horizontal plane in the heat collection water tank inner chamber.It is the mode of heating in parallel to the water in the heat collection water tank that the solar heat collector of this set, each vacuum are adopted heat pipe, and in the casing water base only along up and down direction operation, and it is basic identical that heat collection water tank and different vacuum are adopted the water temperature of sustained height in the heat pipe.Owing to be subjected to the restriction of field of employment, single vacuum is adopted the length of heat pipe can not be oversize, the solar energy evacuated length of tube that uses is generally 1.2 meters to 2.3 meters at present, the acquisition sensible heat is few water is finished once circulation in vacuum is adopted heat pipe after, the temperature ascensional range is little, and the water temperature in the heat collection water tank is just whole slowly to rise.Therefore, existing solar energy heat collector generally can only be used as water heater, though also can reach boiling temperature in short-term at the water of the sunny weather heat collection water tank of summer high temperature, also is difficult to the long-time steam that continues to obtain.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of utilize solar energy fast, continue to produce steam, and the less steam raising plant of the temperature effect of being bullied.
For solving the problems of the technologies described above, the present invention includes support body, the heat collection water tank and the solar energy that are connected are installed on the described support body adopt heat pipe, solar energy is adopted the heat pipe tube chamber and is communicated with the heat collection water tank inner chamber, the heat collection water tank two ends are respectively equipped with water inlet and the steam (vapor) outlet that communicates with its inner chamber, be connected to water replanishing device on the water inlet, its design feature be described heat collection water tank the casing major axis to level to setting in a certain angle, and its steam output end head height in the water inlet termination; Be provided with many solar energy side by side along the side of heat collection water tank length direction and adopt heat pipe, the mouth of pipe that different solar energy are adopted heat pipe raises from bottom to top successively with the heat collection water tank gradient.
Described heat collection water tank is long barrel shape, its inner chamber body length is 2 to 3 meters, cross section is less than 0.16 square metre, and described water replanishing device is the automatic water-replenishing device of keeping liquid level, solar energy is installed on the heat collection water tank is adopted the casing side of heat pipe and be not less than 30 with level to angle and spend.
Described heat collection water tank inner chamber cross section is that the length of side is 20 to 30 centimetres of squares, and the heat collection water tank bottom side vertically is connected to 25 to 30 solar energy and adopts heat pipe, and solar energy is installed on the described heat collection water tank, and to adopt casing side and the level of heat pipe be the 40-50 degree to angle.
The described heat collection water tank left and right sides is equipped with solar energy and adopts heat pipe, described heat collection water tank is equipped with that solar energy is adopted the casing side of heat pipe and level is 90 degree to angle, steam (vapor) outlet and water inlet lay respectively at the upper/lower terminal of heat collection water tank, and the angle that solar energy is adopted heat pipe and heat collection water tank is 30 to 60 degree.
Heat collection water tank of the present invention is non-to be horizontally disposed with, and its steam output end head height is in the water inlet termination.The mouth of pipe that many solar energy that are arranged side by side on the heat collection water tank are adopted heat pipe also raises from bottom to top successively with the angle of inclination of heat collection water tank.Heat collection water tank adds the starting stage behind the water, though the water temperature that different solar energy are adopted in the heat pipe is identical, but after solar energy is adopted heat pipe and is accepted to shine upon, water temperature rises immediately in the pipe, because water body has the character of thermally stratified layer, the water body in the pipe axially forms circulation in the pipe along body, and high-temperature water constantly compiles and enters heat collection water tank to the mouth of pipe, cold water enters body in the heat collection water tank, forms water circulation up and down.Equally, after hot water entered heat collection water tank, because heat collection water tank is the installation of tilting, water body also formed in the case along casing and circulates in the case, and high-temperature water is constantly compiled to steam output end.This continuous two-way shuttling movement, make the water in the heat collection water tank form temperature contrast along differing heights, the water temperature difference of different solar pipe correspondences, and be that temperature constantly raises from the bottom up, this is equivalent to many solar energy and adopts heat pipe series connection relay heating, and the top vacuum tube is the highest water body of heating-up temperature always.Heat compiles toward high quick transmission from low, makes part water at first be heated vaporization in the vacuum tube of top, and it is fast and lasting to produce steam, and it is little influenced by day temperature.Through test, adopt the design's solar steam generator, when temperature drops to about subzero 10 degree, under the fine situation, still can continue to produce water vapour 2-3 hour, and the steam that produces can reach the degree of utilization, solar energy effective rate of utilization height.
