Abstract
The utility model provides an external-spotlighting and eccentric solar vacuum heat collecting pipe which comprises an external pipe, an internal pipe and a vacuum layer arranged between the internal pipe and the external pipe. The external-spotlighting and eccentric solar vacuum heat collecting pipe is characterized in that the internal pipe is a transparent pipe, and the inner pipe is internally provided with a metal pressure carrying pipe, wherein the surface of the metal pressure carrying pipe is coated with a heat-absorbing material layer. With the advantage that the metal pressure carrying pipe can fast transfer the heat, the external-spotlighting and eccentric solar vacuum heat collecting pipe furthest completes the solar light-heat conversion, shortens the time that the pipe is heated up by heating medium, and improves the heat collecting efficiency; and as the collected solar energy is reflected to the sun shielding surface at the bottom of the vacuum heat collecting pipe by a light collecting cover and a light reflecting material layer on the inner surface of the light collecting cover, the external-spotlighting and eccentric solar vacuum heat collecting pipe effectively enlarges the heat absorbing area, further reinforces the heat collecting efficiency, and greatly improves the use ratio of the solar energy. Furthermore, the heat energy generated by the pipe can meet various requirements of the industrial thermodynamics.
Description
Technical field
The utility model provides a kind of concentrating solar vacuum heat collection pipe, and the outer concentrating solar vacuum tube of particularly a kind of off-centre belongs to application of solar.
Background technology
Solar energy is as a kind of inexhaustible clean energy resource, more and more obtained people's attention and utilized in a large number, and solar heater is exactly a kind of helioplant wherein.Most important parts is a vacuum heat collection pipe in the solar heater, yet because technology and structural reason, the interior Guan Yin of existing solar vacuum heat-collecting pipe does not possess the solar collecting performance of high concentration ratio and exists the energy-flux density of effective heat-absorbent surface low, problems such as heat build-up efficient is low, vacuum heat collection pipe bottom opaco can't carry out thermal-arrest in addition, therefore, make the heated medium in the vacuum tube need just can be heated for a long time, and in can not obtaining, high-temperature, greatly reduce the effect of utilizing of solar energy, limited the application of vacuum heat collection pipe in industrial steam boiler.Therefore be necessary prior art is improved.
Summary of the invention
Do not have high optically focused, solar collecting performance for overcoming existing solar vacuum heat-collecting pipe because of interior pipe, the bottom opaco again can't thermal-arrest, thereby cause that endotherm area is little, heat absorption efficiency is low, the problem that can not in solar energy medium and high temperature field, widely apply, the utility model provides a kind of off-centre outer Photospot solar vacuum heat collection pipe, make solar energy-Re transformation energy satisfy industrial thermodynamic medium and high temperature and provide saturated vapor or the requirement of superheated steam, improve solar energy utilization ratio.
The utility model is finished by following technical proposal: the outer Photospot solar vacuum heat collection pipe of a kind of off-centre, comprise the vacuum layer between outer tube, interior pipe and the inner and outer pipes, pipe is transparent pipe in it is characterized in that, and is provided with the metal pressure-bearing pipe that its surface is coated with the heat-absorbing material layer in the interior pipe.To utilize the metal pressure-bearing pipe fast advantage of conducting heat, absorb solar thermal energy rapidly, and the heat energy that absorbs is passed to heated medium in the pipe fast, shorten heat time heating time, improve the thermal efficiency.
Described vacuum heat collection pipe off-centre places its inner surface to scribble in the arc snoot of reflective material layer, with by the reflective material layer on snoot and the inner surface thereof with the solar energy reflection assembled opaco bottom the vacuum heat collection pipe, enlarge effective endotherm area, further the reinforcement collecting efficiency.
The diameter ratio of the width of described snoot or the chord length of circular arc and metal pressure-bearing pipe was greater than 4: 1, and the radian of snoot arc is 120～180 degree.
The utlity model has following advantage and effect: adopt such scheme, promptly utilize the fast advantage of metal pressure-bearing pipe heat transfer, finish solar energy-Re conversion to greatest extent, shorten the heat time heating time of heated medium, improve collecting efficiency, simultaneously by the reflective material layer on snoot and the inner surface thereof with the solar energy reflection assembled opaco bottom the vacuum heat collection pipe, enlarge effective endotherm area, further reinforcement collecting efficiency, improved solar energy utilization rate greatly, the heat energy of its generation satisfies the thermodynamic various needs of industry.The utility model can utilize the generation technology and the equipment of conventional circular vacuum tube simultaneously, its difficulty of processing is the condensing evacuated pipe of pipe vacuum tube and dual paraboloid outside ellipse also, reducing the production cost of high concentration ratio vacuum heat collection pipe, is a desirable Application of Solar Energy equipment in fact.
