Problems solved by technology
[0003] Solar energy utilization is mainly divided into photoelectric utilization and solar thermal utilization. At present, solar thermal utilization is mainly solar water heaters. Solar water heaters are divided into suffocating type and circulation type. The circulation type has higher efficiency. The heat collector mainly adopts metal tube plate heat collection Both have the following disadvantages: 1. The metal tube plate heat collector is mainly made of copper, aluminum and other materials, and the structure and manufacturing process of the vacuum glass tube heat collector are relatively complicated. The heat absorption area is calculated and the price of both is relatively high
2. Both of them use black sunlight-absorbing paint applied at low temperature. Under the long-term sunlight, there will be a certain degree of aging to attenuate the sunlight absorption rate, which is one of the reasons for the efficiency and life problems.
3. Difficult to integrate with buildings due to material and structure reasons
However, vanadium-titanium black porcelain uses vanadium extraction tailings as the main raw material. At present, the demand and production volume of vanadium are not large, resulting in a certain limit in the output of vanadium extraction tailings. Composite ceramic hollow solar collector plates based on conventional ceramics are very necessary to make more effective use of vanadium extraction tailings

Embodiment
[0031] 1. Common ceramic raw materials clay, quartz, feldspar are crushed and ball-milled to become ordinary ceramic mud. After passing through a 200-mesh vibrating screen, excess water is removed by pressure filtration to form a mud cake. After rough refining, a vacuum mud mixer is used to squeeze it into a mud section. Put it into the stale house, and then use a vacuum extruder to extrude it into a porous through-hole plate with a width of 500 mm, a thickness of 38 mm, 12 holes in the middle, a thickness of the hole wall of 5 mm, and a length of 1000 mm. The partial partition wall at the end of the through hole connects the two ends of the through hole to form a through hole plate connected to the end of the hole. The two ends of the through hole plate are bonded with plugs with inlet and outlet of the same material, which becomes a ceramic hollow plate green body. Such asfigure 1 As shown, after the ceramic hollow blank plate is dried, stand it upright to extract 65% of vana...

Abstract
Black ceramic manufactured by taking vanadium residue as one of raw materials is called as vanadium / titanium black porcelain with a sunlight absorption rate of 0.9 and is an excellent photo-thermal conversion material; as the production amount of the vanadium residue is finite, the invention proposes a method comprising that: the vanadium / titanium black porcelain is taken as inner, outer surface layers, a hollow ceramic plate formed by the extrusion of normal ceramic raw materials is taken as a substrate, both are synthesized to a composite ceramic hollow solar heat-collection plate such thatthe vanadium residue and the vanadium / titanium black porcelain are utilized in a more effective way.
