Problems solved by technology

[0002] Solar energy is renewable, inexhaustible, and green energy that does not harm the environment. It is also an unstable, thin, and low-density energy source. Solar light and heat utilization mainly uses solar water heaters. The key component of solar water heaters is solar heat collectors. At present, they are mainly Vacuum glass tubes and copper-aluminum composite heat collectors both have the following disadvantages: 1. High price - hundreds of yuan per square meter; 2. Short life - metals are easy to corrode, especially welds are easy to corrode, vacuum The glass tube has problems such as vacuum life and easy breakage of the tube body, which makes it difficult for the average life of the two to reach 10 years; 3. The average efficiency is not high-both use low-te

Embodiment

[0028] 1. The ceramic industry usually considers inferior raw materials with iron oxide content of 5% and titanium oxide content of 3.2% to make mud with ordinary ceramic equipment and technology, and vacuum extruder after vacuum refining and aging. Extrude it into a porous through-hole plate body, remove the mud between the two holes at both ends, and make another plug of the same material with an inlet and outlet nozzle and paste it on the two end faces of the multi-hole through-hole plate , so that the nozzles at both ends communicate with each hole in the through-hole plate to form a ceramic solar panel slab, and the slab is dried and fired to become a ceramic solar panel with a gray surface.

[0029] 2. the method as described in embodiment 1, adopts the red clay that iron oxide content is 9%, and the ceramic solar panel that manufactures is red.

[0030] 3. method as described in embodiment 1, adopt common ceramic raw material and ferromanganese slag as raw material, whe...

Abstract

This invention relates to production of multiple through-hole plate, made of mineral material, used as solar-energy collection plate. The raw materials of this inventive products are: common ceramic material, industrial slag with the total weight of transition elements compounds being more than 5%, and metallic ore with the total weight of transition elements being more then 20%. Above-mentioned raw materials are processed into mud by using ordinary method, and then extruded to produce multiple through-hole plates. The plates are connected end-to-end. Thus produced plate is then equipped with stops having outlets at its two ends, so formed is the blank of solar-energy collection plate, which is then dried, sintered to produce this inventive ceramic solar-energy plate or solar-energy plate covered with deep colour or black ceramic layer. Compared with prior art solar-energy-collection unit, such as vacuum-glass tubes or composite copper/aluminium solar-energy unit, this inventive products have advantages of: low cost, long service life and high efficiency.

Description

(1) Technical field [0001] The present invention relates to a method for utilizing solar energy, in particular to a method for manufacturing a solar heat collector, and in more detail to making ceramic solar heat collectors with ordinary ceramic raw materials, industrial waste rich in transition elements, and metal minerals as raw materials Methods. (2) Background technology [0002] Solar energy is renewable, inexhaustible, and green energy that does not harm the environment. It is also an unstable, thin, and low-density energy source. Solar light and heat utilization mainly uses solar water heaters. The key component of solar water heaters is solar heat collectors. At present, they are mainly Vacuum glass tubes and copper-aluminum composite heat collectors both have the following disadvantages: 1. High price - hundreds of yuan per square meter; 2. Short life - metals are easy to corrode, especially welds are easy to corrode, vacuum The glass tube has problems such as vacu...
