Abstract

The utility model relates to a parabolic convex groove reflecting mirror focusing solar energy power generating and water purifying device, which belongs to the solar energy development and utilization technology. The purpose of designing the device is to focus the solar energy of large area and to convert the solar energy into electric power with an expensive device for household use. The cross section made of metal thin plate or plastic plate coated with reflecting film adopts a parabolic groove shaped reflecting mirror, the head and tail of the groove is orderly arranged toward the east and the west, and the groove mirror surface is arranged on the roof facing the south. The parallelly emitting sunlight is reflected and focused to the focal point of the parabola through the mirror surface, the parabola focus point in the groove is extended into a straight line along the groove in double directions, a water pipe is fixed on a straight line of the focus point to absorb the sun light energy focused from the reflecting mirror to heat the water inside the pipe into high temperature water vapor flow, so as to rush a turbo machine to generate electricity, and the distilled water can be obtained through a double-layer heat exchanging tube. By using the simple device, not only clean energy source and distilled water can be obtained, but also the land surface temperature is reduced, therefore, the utility model has multiple effects.

Description

Parabola matrix groove focusing mirror solar electrical energy generation, purifier

Technical field:

The utility model belongs to solar energy development and utilizes technology, and usefulness parabola matrix groove speculum on water pipe, is heated as device that high-temperature vapor stream be used for generate electricity with the water in the water pipe with solar focusing.

Background technology:

The development and use of solar energy have had the history of decades, and solar water heater wherein provides sufficient hot water with the device of cheapness for us, but its function singleness utilizes scope not wide.Solar energy voltaic battery can directly change the luminous energy of the sun into electric energy, but because crystalline silicon costs an arm and a leg, makes it be difficult to enter common people house.The sun has been carried a large amount of luminous energy to the earth, but sunshine is uniformly dispersed, and the energy that unit are can be collected is few.Large-area sunshine being gathered together and convenient the utilization as a kind of device of cheapness how, is the key that solar energy development utilizes technology.

Summary of the invention:

Task of the present utility model provides a kind of simple in structure, and is with low cost, can and change the device of electric energy into large-area sunlight collection.Parabola is done cross section both direction extension forwards, backwards becomes parabolic concave type groove, and the also two-way straight line that extends to of parabolic focus claims that it is the focus straight line.With sheet metal is that material is made such concave groove mirror surface, then the parallel sunray over against it will all focus on the focus straight line, on the focus straight line, fix the water that a water pipe is used for absorbing solar energy in the heating pipe and become high-temperature vapor stream, with its get excited gas-turbine generating, and obtain distilled water.

Description of drawings:

Accompanying drawing is a parabola matrix groove focusing mirror solar electrical energy generation purifier, and Fig. 1 is family's roof usefulness, and Fig. 2 is open-air using.

The specific embodiment:

The home-use loop that multiple arrangement is connected into closure covers whole roof, as far as possible for family provides more electric power and distilled water.Open-air usefulness the multiple arrangement straight line is connected, the steam of previous device after by gas-turbine leads to a back device and heats generating again, and to water-deficient area transporting water steam far away.Two kinds of devices have identical basic structure: 1, feed cistern, and 2, feed pipe, 3, the ball float gate valve, be used for controlling the water yield that enters the focus water pipe.The interior water of focus water pipe to be difficult for rapidly water being heated to be steam, and water has lacked can burn out water pipe.4, parabola matrix groove speculum is used for focusing sunlight.5, focus water pipe becomes high-temperature vapor stream with the water that focuses in the next solar energy heating pipe.For keeping the one-way flow of steam, the focus water pipe should be low early and high after, causes the fluid-tight of water inlet pipe mouth, and difference in height should be a bit larger tham the water pipe diameter.6, gas-turbine, 7, generator, 8, heat-exchange tube, heat-exchange tube is double-deck, interior pipe carries the steam that comes out from gas-turbine, outer tube to carry the cold water that comes from feed pipe.Steam and cold water reverse flow by the heat exchange of inner tubal wall, with feeding the cold water preheating of focus water pipe, are cooled to distilled water with steam, flow into distilled water tank 9.The steam that last device comes out can only forward flow with cold water pipe, because pipeline is longer, is unlikely to influence too much heat exchanger effectiveness.The water pipe that comes out from gas-turbine is bent downwardly, be half of gas-turbine height with the height of the water surface in the height of heat-exchange tube infall and the ball float gate valve, whenever to guarantee in the focus water pipe semicanal water being arranged all, solar irradiation just is mapped to and can starts working, water pipe can not burnt out yet, and one-way cock 10 is housed each device front end of open-air usefulness and side pipe and high pressure valve are equipped with in valve 11 rear ends.Night and cloudy day do not have sunlight, and valve 11 is opened automatically, and the cold water from feed pipe is full of half height of focus water pipe, and valve 10 is closed automatically, to guarantee whenever solar radiation all has water to absorb the unlikely water pipe that burns out of heat in water pipe.Daytime, the steam that last device comes was washed valve 10 open during solar radiation, and valve 11 is closed automatically, and each device sequence is started working.When last device has solar radiation, back one device is sheltered from heat or light by cloud mass, then ponding increases gradually in the back device water pipe, the pipe internal pressure constantly increases, influence front device work, at this moment side pipe 12 inner high voltage valves 13 are washed open, and steam feeds the feed cistern of next device from side pipe, single assembly should be longer as far as possible under the situation of conditions permit for the device of open-air usefulness, can improve the ability of single assembly generating and transporting water steam.

Each device all should be installed by east-west direction.Sunshine oblique fire from east to west in the morning, afternoon is oblique fire from west to east, parabola matrix groove speculum has only strict with the east-west direction installation, could guarantee whenever sunlight can both shine is not subjected on the minute surface self to block, also sunlight can both be focused on the focus water pipe, the oblique fire from south to north of Northern Hemisphere sunlight, minute surface should south tilt.Along with changes of seasons, answer the knob 14 on the timely adjustment minute surface support, make speculum face the sun.

This device if can be on the roof, wasteland, lake surface, river surface, desert, even a large amount of uses are dissolved in the sea, not only can obtain a large amount of clean energy resourcies and pure water, evaporation, reduction urban heat land effect to reducing ground moisture reduce the earth surface temperature and all will play an important role.
