Novel combined type solar thermal collector

Abstract

A novel combined type solar thermal collector is extremely advanced large cross profile solar energy collection equipment and is designed by using a focusing theory when a parabola faces light. When sunlight penetrates through a glass plate to irradiate on a parabola spotlight reflection face, the sunlight is regularly focused and reflected on a thermal collecting pipe and enables light density on the surface of the thermal collecting pipe to be greatly increased, ambient temperature of the thermal collecting pipe is increased exponentially, and thermal collecting efficiency of the thermal collecting pipe is high. The novel combined type solar thermal collector is convenient to install and use, high pressure resistant and capable of producing high pressure steam, can not only solve basic problems of washing and bathing, but also solve problems of drinking water and food cooking and is capable of being combined with a floor heater or central heating to use for heating in winter. The most important advantage of the novel combined type solar thermal collector is capable of being installed in a large-scale collection mode to produce the high pressure steam to drive a steam turbine for generating electricity.

Description

New hybrid solar collectors

Those of skill

[0001] The invention belongs to the large cross-section an in HPHT reflector concentrating collectors. Background technique

[0002] At present, the domestic solar collector device is nothing more than two: one is a glass tube type collector tube, low cost but can not be run under pressure, collector general effect, can not boil water. Another is a flat plate solar collector panel, technology-based imported, higher cost, but can be run under pressure, the higher the effect of the collector, still can not boil water. The limitations of these two ways is the limited collection tube collectors of received light density, ambient temperature is not high, leading to a general effect collector, solar water heaters so now only stay in a narrow range of wash bath.

[0003] abroad, it has been the use of solar energy as a deep study, using high temperature and pressure and heat such as solar thermal power, but because of their overall large collector, condensing surfaces exposed to the air, easily contaminated and oxidized, low thermal efficiency , high cost, it is not the actual promotion of the use, just stay on an experimental basis.

SUMMARY

[0004] for the current shortage of solar collectors, we have designed this new type of hybrid solar collector. The main idea is to design the parabolic surface with a focused principle, increasing the density of light around the collector tube; Protective effect of the inert gas and the heat loss is reduced to prevent oxidation of the reflecting surface of the principles of the design.

[0005] The invention solution: new composite solar collector comprises a housing, insulation, reflective surface, the metal collector tube, high strength glass, pipe joints, mouth ventilation. The housing is made of high-strength metal rolled plate; reflective surface is formed by using the principle of concentrating parabolic reflector facing the light, are regularly disposed within the housing; a reflective surface of the housing interposed insulation material filled into the cavity formed insulation; collector tube is a metal tube coated with a coating film collectors, welding both ends of the nozzle pipe joints, then fixed in a recess of the reflection surface, so that the focal line and the center line of the heat collecting pipe of the reflecting surface coincides tube protruding housing side walls splice, and tight welding; welding ventilation nozzle housing sidewall; upper opening of the housing hermetically enclosed high-strength glass, and finally through the mouth of the ventilation air inside the casing is replaced with an inert gas.

[0006] When the sunlight collecting reflector surface through the glass plate, the regular reflection is focused onto a collection tube, so that the light density of the surface of the collector pipe a substantial increase in the ambient temperature doubled. Since the reflective surface protective inert gas, so it will not rust or oxidation adhesion of dust, the metal tube open at both ends and has a heat collecting pipe joints, easy to use and to install the convection of water, and high pressure.

[0007] The beneficial effects of the invention are: The new solar panels high collection efficiency, ease of installation, high pressure, can produce high pressure steam. Not only can solve the basic problem of washing bath, and can solve the problem of drinking and cooking food; use can also be combined with floor heating or radiators for heating in winter; the most important is the large cartridge produces high-pressure steam to drive a steam turbine to generate electricity .

detailed description

[0012] The new composite solar collector comprises a housing (6), insulating layer (7), a reflecting surface (5), metal collector tube (3), high-strength glass O), pipe joints (1), mouth ventilation G). A housing (6) is a rolled metal plate with high strength; a reflective surface (5) facing the parabolic concentrator using the principle of reflection of light made regularly disposed within the housing (6); a reflective surface (5 ) and the housing (6) is sandwiched insulation material filled into the cavity, forming the insulation layer (7); collector tube C3) is a metal tube coated with a coating film collectors, welding both ends of the nozzle line connection (1), and then fixed reflecting surface in the recess (5) of the reflecting surface (5) and the center line of the line focus of the heat collecting pipe (3) coincides ⑴ projecting line connection housing (6) side walls, and welded tight; a housing (6) side wall welding ventilation nozzle, the housing (6) hermetically enclosed high-strength glass catchy O), and finally through the ventilation nozzle (4) the housing (6) replacing the air inside the inert gas .

[0013] When a high intensity of sunlight through the glass plate (2) to the condensing and reflecting surface (5), the regular reflection is focused onto the collector pipe C3), that the collector tube C3) significantly increase the light density on the surface, their environment temperature doubled. Since (5) is protected with inert gas reflective surface, so it will not rust or oxidation adhesion of dust, metal collector tube C3) open at both ends and has a line connection (1), and easy to install using water convection.
