Abstract
A new method of collecting and condensing of solar energy for large area utilizes the straight groove shape specific structure with parabola performance formed by curved surface of indentation bottom face to reflect and condenses the solar light incoming in parallel with the parabola symmetry axis on a straight line in the groove. The pipe fixed along the straight line will be heated by high temperature to condense the solar light and light tracing will be realized by angle changing of straight indentation with the heating tube as an axis and with no heating tube twisting. The devices can be connected to the pipes in parallel or in series for large area industral solar energy application.
Description
The present invention relates to the utilization of solar energy, is a kind of collection of uniqueness and the new method of polymerization sunray.
The scheme of prior art solar energy utilization roughly has following three classes:
1, solar cell.Solar energy directly can be changed into electric energy, but transformation efficiency is low, the energy small scale, the cost height, application surface is narrow, can not realize the large tracts of land collection of solar energy.
2, the polymerization sunshine is gathered in the mirroring of parabola ball impression face.The advantage of this type of technical scheme has been to improve the energy level of solar energy, can realize the heating of light direct projection tracking high temperature dot, and temperature can reach more than 1000 ℃.But because the some mode of heating can't be realized multiple-unit large tracts of land combination, make unrealisticly, therefore do not reach the level of large tracts of land industrialized utilization and cross bigbore concave spherical mirror.
3, fixing non-tracking mode is lower than the solar water heater of water boiling point heating.Be widely used, cost is low, but efficient is lower, and the energy level temperature is low, can only enter family, hotel, as the bathing thermal source, and the level of the industrialized utilization that is far from being.
Although the technology of existing solar energy utilization has had certain progress in a word,, still belong to the exploitation of lower level generally owing to do not reach large tracts of land industrialized utilization level.
If want to realize the industrialized utilization of solar energy, must solve the problem of two aspects: the one, the energy level that improves solar energy is the polymerization heating-up temperature, the 2nd, the large tracts of land collection of solar energy.Preceding problem, parabola concave surface mirror is adopted aggregation technique and can be solved sunlight, make undue difficulty but cross bigbore speculum, and the some heat characteristic of this technology can't realize multiunit combination, and second problem can't be solved.
Purpose of the present invention solves above said second problem exactly.The unique distinction of this method is " line " polymerization is changed in " point " polymerization of parabola concave surface mirror, solar energy is become line promptly to the heating of pipeline the heating of point, and pipeline both can have been derived heated medium because of it and can have been realized multiple-unit connection in series-parallel combination, therefore can realize the large tracts of land collection of solar energy.
As follows for reaching the technical method that goal of the invention takes:
Adopt the bottom surface curved surface to have reception and the reflection polyplant of the straight groove of parabolic characteristic as sunray.This groove floor (seeing accompanying drawing) is that 2. 1. parabola be reference point with its focus, along forming with the continuous translation of plane, parabola place vertical direction.Fixing water back 3. on the formed linear position of focus movement locus 2. in the translation process, 4. whole straight groove two end side panels is rigidly connected with groove, and 3. groove serves as that axle can be done less than 180 ° reverse with pipeline.Pipeline axially can level and vertical between do swing less than 90 °.
When light is injected in the groove along the direction parallel with the parabola symmetry axis, the groove floor of coating reflectorized material can accumulate in the incident ray reflection on the water back, realizes the heating of solar energy polymerization high-temperature pipe.The all-weather traction of sunshine is realized by reversing with the swing of water back of groove, water back itself does not take place radially to twist, such design feature can make the multiple-unit harvester 5. realize connection in series-parallel by pipeline and follow the tracks of 6. synchronously, can multiple-unit, gather solar energy in large area.
Compare with the solar energy utilization of prior art, the breakthrough part of this invention is:
1, the collection polymerization of sunray is not " point " polymerization but " line " polymerization, the medium in both can this high-temperature heating pipe road, and the thermal conductance of pipeline goes out and the connection in series-parallel solar energy in large area key of gathering just.
2, particular structure makes and is heated the swing that axially certain permission amplitude only takes place pipeline, radially do not reverse and can not produce, realized that simultaneously the multiple-unit connection in series-parallel combination of this device and the interlock of light follow the tracks of synchronously, for the large tracts of land industrialized utilization of solar energy has found the breach.
3, groove is simple in structure, and cost is low, repdocutbility good, and existing technology level can be competent at its manufacturing fully, and cost of manufacture can be accepted.
Claims (1)
- A kind of solar energy in large area that is applicable to is gathered the new method of polymerization, it is characterized in that:The groove bottom curved surface of the solar collecting device of straight fluted body has parabolic characteristic, its strict mathematical description is: parabola is reference point with its focus, along the direction continuous translation formed curved surface vertical, be the groove floor of this device with plane, parabola place; Concave surface coating reflectorized material is gathered in the groove on a certain the straight line after reflection with the sunshine of the parallel incident of parabola symmetry axis, and this straight line is the parabolic focus track; Fixing water back on the linear position of focal track, the sunlight energy of polymerization carries out the high temperature heating to pipeline internal medium; But straight groove with the water back be the axle windup-degree less than 180 °, water back axially by level to vertically doing less than 90 ° of swings, can realize the direct projection tracking of sunlight and water back itself does not take place radially to twist.
