Problems solved by technology
[0004] There are many advantages in using composite ceramic solar hollow panels to make solar air ducts, but after repeated tests and continuous research by the inventor, it is found that it still has shortcomings: when building ceramic solar air ducts in desert areas, it is necessary to build large-scale solar wind ducts. Road, composite ceramic solar hollow panels are limited by the ceramic production process, the height and width of the channels are generally between 20 and 50 mm, which cannot meet the requirements, and the manufacturing process of large-channel composite ceramic solar hollow panels is very complicated and difficult in technology At the same time, the composite ceramic solar hollow panel has a large heat capacity, which absorbs a large amount of heat energy in the solar air duct, thereby consuming the energy in the solar air duct and affecting the wind force of the solar air duct
The above deficiencies tend to make the production cost of the solar air duct relatively high, and make the technical implementation quite complicated and the efficiency low

Abstract
A solar collecting panel of composite ceramic material and a solar fluted air duct are provided. The solar collecting panel has a rectangular shape and is constituted of a common ceramic solid flat plate and a sintered black ceramic layer covering the flat plate. The black ceramic layer is vanadium-titanium black ceramic layer, waste residue black ceramic layer or ores black ceramic layer, whose surface is coarse and distributed with tiny holes. Two sides along the longitude direction of the solar collecting panel are provided with side plates respectively to form a solar collecting fluted plate. The bottom and the outsides of lateral sides of the fluted plate are provided with a bottom plate and two side plates respectively, and a transparent plate is provided on the top of the two side plates to form a solar collecting fluted channel with a front and back end opened. The solar fluted air duct is formed of multiple solar collecting fluted channels, which are connected with one another end to end.
Description
technical field [0001] The invention relates to solar energy utilization technology, which is a composite ceramic solar heat collecting plate and a solar trough air duct. Specifically, low-cost, long-life, dark-colored or black-colored ordinary ceramic solid flat plates or ordinary ceramic solid slabs are used as solar energy by using industrial waste rich in fourth-period transition metal elements, natural minerals, and ordinary ceramic raw materials. Heat collector panels, using solar trough-shaped air ducts made of solar heat collector panels to generate hot air, which provides heat for buildings or is used to heat air on barren slopes and deserts on a large scale, and the rising hot airflow drives turbines to generate electricity. Background technique [0002] In recent years, some countries have carried out a research experiment on a solar thermal power generation method called "solar greenhouse chimney". The solar greenhouse chimney power generation system is mainly c...
