Description
Technical field
The present invention relates to a kind of solar energy vacuum tube matrix collecting system, belong to technical field of solar.
Background technology
Current society advocates sustainable development, and wherein, energy problem is the key issue of restriction human kind sustainable development.A kind of as energy source; Solar energy is inexhaustible, nexhaustible; The annual solar energy irradiation that obtains of the earth is tens thousand of times of human all energy resource consumptions, if can transform fully and utilize this part energy, will energy safeguard be provided for human kind sustainable development.Though have a large amount of research staff to pay a lot of performing creative labours, because the energy density of the human solar energy that can receive is low, quality is low, so still very big to its technical difficulty of carrying out extensive direct utilization for the utilization of solar energy.
The Application of Solar Energy technology of comparative maturity mainly contains photoelectricity conversion and photo-thermal conversion two big classes at present.Wherein, the solar energy optical-thermal transformation technology comprises focusing heat collection and vacuum heat-collecting two big classes.
Focusing heat collection comprises technical methods such as tower heliostat focusing, slot type focusing and the focusing of dish formula, through focusing on, has improved the energy density of solar energy, can obtain high temperature and high pressure steam, has improved the quality of solar energy.But low owing to technical sophistication, photo-thermal transformation efficiency, heat-energy losses big, the focusing technology cost of investment is crossed high reason, do not possess the condition of extensive use, still is in the scientific research development, rarely has application example.
Vacuum heat-collecting mainly is the solar vacuum heat-collecting pipe technology, is a successful model of human use's solar energy resources, is that the solar water heater of core can be used under various environment, weather conditions with the vacuum heat collection pipe; Solar vacuum heat-collecting pipe has certain dimensions at present; In view of technology and cost problem, it is very big that solar vacuum heat-collecting pipe can not be done, and the size of existing solar vacuum heat-collecting pipe is limited; The heating surface area of vacuum heat collection pipe is little; The heat energy that every vacuum heat collection pipe can obtain is very limited, and under the abundant condition of sunlight, the conventional commercially available vacuum heat collection pipe of a maximum collecting efficiency per hour also can only enough obtain the heat energy of 50 kilocalories; If per hour will obtain 1 ton of steam, then need 20,000 thermal-collecting tubes to work simultaneously and just can realize; And in the existing heat supply process; According to the difference of heat demand, the quantity of steam of most of Industrial Boilers is far longer than 1 ton, even reaches tens of tons, hundreds of ton; If use solar vacuum heat-collecting pipe to obtain so huge heat energy; Then need the very huge vacuum heat collection pipe of quantity to work simultaneously, have only reasonably vacuum heat collection pipe with huge quantity to carry out layout and connect the solar energy vacuum tube collecting system that just can obtain to have economy.
The connected mode of common solar vacuum heat-collecting pipe comprises parallel way and series system; Vacuum heat-collecting system for above-mentioned imperial scale; If employing series system; To equal each series connection individuality be the resistance sum of each solar vacuum heat-collecting pipe to the resistance of series system entire system so, and resistance has also been realized series connection in the time of individual the series connection, considers factors such as cost and efficient; The drag overall of system can not infinitely increase, so the serial number of solar vacuum heat-collecting pipe also can not infinitely increase in the system; By and large, because vacuum heat collection pipe series connection back resistance superposes, so if the series connection of vacuum heat collection pipe that will be a large amount of will have influence on the flowing velocity of the interior medium of vacuum heat collection pipe train so; Flowing velocity too slowly easily after heat absorption the solar vacuum heat-collecting pipe part high temperature appears; Can make so local medium vaporization to produce vapour lock, will be thereby in the media flow process, in a single day flow through by instant vaporization at the local medium that produces vaporization; Can't realize the smooth circulation heat absorption of medium in vacuum heat collection pipe; Influenced heat absorption efficiency, thus adopt series system can only connect ten several, tens of vacuum heat collection pipes only at the most.
For parallel way; In the prior art, Chinese patent file CN201355026Y discloses the solar steam generator that a kind of medium is a conduction oil, and said steam generator comprises that by several media be the solar thermal collector assembly that the unit heat collector of conduction oil composes in parallel; In each unit heat collector, be provided with a plurality of solar vacuum heat-collecting pipes that are connected in parallel; Thereby form the vacuum heat collection pipe parallel connection on the whole and formed the pipe group, the vacuum heat-collecting permutation and combination of pipe group and Guan Zuzai parallel connection, the above-mentioned mode that is connected in parallel is than the mode of being connected in series; The resistance of vacuum heat-collecting internal system is less, but still there is following problem in it:
The first, owing to even if the length of each identical vacuum heat collection pipe of specification all can not be identical; And each vacuum heat collection pipe during fabrication the welding precision of its weld seam also be incomplete same; So cause the inner media flow environment of each vacuum heat collection pipe different; Thereby it is all different to show as the inner resistance of in whole vacuum heat-collecting system each vacuum heat collection pipe, so just can't realize system-wide impedance match.The unmatched problem of above-mentioned resistance causes the flow of medium between each pipe group different, owing to be the parallel connection relation, it is just different more to get into the inner rate-of flow of each inner vacuum heat collection pipe of pipe group; Thereby cause the medium heating behind vacuum heat collection pipe inhomogeneous, rate-of flow is low in some vacuum heat collection pipe, and then temperature is high; Rate-of flow is high in some vacuum heat collection pipe; Then temperature is low, certainly will influence the whole efficiency of vacuum heat-collecting system, that is to say; The parallel connection method of parallel connection again can't solve the assignment of traffic problem, has amplified the inhomogeneities of flow on the contrary on the contrary.
The second, adopt above-mentioned group of interior parallel connection, the parallelly connected vacuum heat-collecting system of Guan Zuzai; This system only has a water inlet pipe and an outlet pipe; Medium in said vacuum heat-collecting internal system is equivalent to only heat through a vacuum heat collection pipe, and is very low with hot quality.
In order to solve the existing problem of mode of the above-mentioned perhaps a plurality of solar energy vacuum tubes parallel connections of the simple mode of using a plurality of solar energy vacuum tubes to connect in the solar energy vacuum heat collecting system; In the prior art; Chinese patent document CN201255519Y just discloses a kind of solar energy vacuum heat collecting system that parallelly connected and series system are introduced simultaneously; What this technology related generally to is the syndeton of U-shaped pipe in a kind of water heater heat collection gate; This structure is arranged above and below the vacuum tube of some end openings and laterally is installed in the heat collection gate; Correspondence is provided with a U-shaped pipe in the every vacuum tube, and the plurality of U-shaped pipe has the thermal-collecting tube group of a water inlet and a delivery port through elbow in the open end series connection formation of vacuum tube, and this technology is connected, more said vacuum tube after series connection carried out parallelly connected setting solar energy vacuum tube earlier; Earlier solar energy vacuum tube is connected, produce aforesaid vapour lock problem easily owing to the series connection number is more; In addition; Again the vacuum tube after series connection is carried out parallel connection; Because the internal diameter of its unqualified water inlet person in charge and U-shaped pipe relation, so when causing parallelly connected quantity big easily, it is big that distance water inlet person in charge solar energy vacuum tube far away shows as its interior media flow resistance; Flow sharply descends, and also is easy to produce the vapour lock problem.
In addition; Solar energy vacuum heat collecting system described in this technology its above-mentioned all be to adopt same water inlet pipe and same outlet pipe between the vacuum tube after the parallel connection; For the vacuum tube of each group after series connection, all be that cold water and then hot water go out like this, hot water is concentrated output then.Use the thermal-collecting tube connected mode in the above-mentioned technology; The temperature of the hot water of discharging in the vacuum tube of each group after series connection just obtains after the solar heat that receives behind N thermal-collecting tube of process; After parallel connection, the temperature of the hot water of the final concentrated output that obtains all is the temperature that equals the hot water that vacuum tube obtained of above-mentioned each group after series connection to vacuum tube after the above-mentioned like this series connection again.In fact, the temperature of the hot water that obtain this moment can't reach 100 degrees centigrade fully, and ordinary circumstance can only reach 80 degrees centigrade, can't solar energy fully be utilized the conversion of carrying out heat energy, and the heat energy utilization rate that shows as solar energy is very low.
Can know from above-mentioned analysis; At present for the solar energy vacuum heat collecting system of imperial scale; A rational combination connecting mode does not make the solar energy vacuum heat collecting system after combination have bigger solar energy utilization ratio and thermal energy conversion efficiency, and obtains high-quality heat energy.And in fact do not have tens thousand of, hundreds thousand of, millions of vacuum heat-collecting systems that vacuum heat collection pipe is worked simultaneously really in the prior art yet.
