Ball lens array heat collection system without tracking

Abstract

The invention relates to a solar energy follow-free ball lens array heat collecting system, which forms an array by a plurality of glass ball lenses with diameter of about 3 to 5 cm; in accordance with emergence route figure of the sun in the local latitude and covering face of facula during one year, sphere heat collectors are provided below the ball lens; each row of sphere heat collectors are in series connection with each other via a thermal insulation pipe and connected with the main thermal insulation pipe to a circulation pipeline; a water stream circulation pump is provided at the main thermal insulation pipe, water in a water tank enters into the sphere heat collectors as affected by the circulation pump to be heated to high temperature steam. The invention has the advantages that the ball lens array focusing sunshine is applied, the sphere heat collectors are provided in terms of the emergence route figure of the sun in the local latitude, the water flow circulation pump forces the water flow to circulate, thus realizing the application of follow-free spot-focusing sunshine. The invention can be applied to the fields of heat collection to generate power for the purpose of conquering desert, heat collection systems on the roof and desalting of sea water.

Description

technical field [0001] The invention relates to a solar energy tracking ball-free lens array heat collection system. Background technique [0002] Solar energy collection must adopt a certain technical device, that is, a heat collector. The heat collector can be divided into a concentrating heat collector and a non-concentrating heat collector according to whether it is concentrating; the concentrating heat collector can gather sunlight in a small area On the heat-absorbing surface, a higher temperature can be obtained; but only direct radiation can be used, and the sun needs to be tracked. The concentrating heat collector is mainly composed of three parts: the concentrator, the absorber and the tracking system. According to the principle of concentrating, the concentrating heat collector can be basically divided into two categories: reflection concentrating and refracting light; Rotating parabolic mirror concentrators (point focus) and trough parabolic mirror concentrators...

AI Technical Summary

Problems solved by technology

Obviously, the giant glass convex lens is relatively heavy, with many consumables and complicated manufacturing process; so the refraction concentrator has not been developed for a long time.

Later, someone proposed to use a water-filled lens made of hard transparent plastic to focus and collect light. Although the amount of consumables for the convex lens was reduced; but two-dimensional tracking was required, so it was not well applied in practice.
