Novel black substance application and novel application method thereof

Abstract

The invention relates to a novel black substance application. The novel black substance application is characterized in that black substances are directly used as solar heat collection layers by the aid of excellent photo-thermal conversion characteristics of the black substances, and the black substances include vanadium extraction tailings, industrial black waste residues, natural black minerals, black compounds and black chemical products. A novel application method is characterized in that the black substances are directly used as the solar heat collection layers to construct a building-integrated solar air collector and a building-integrated solar water heater. Compared with the prior art, the novel black substance application and the novel application method have the advantages that construction cost is lowered greatly, service lives of the solar air collector and the solar water heater are prolonged greatly and can be as long as that of a building, the solar air collector and the solar water heater are high in heat collection efficiency, better in heat collection effect, less prone to attenuation after long-time use and quite simple to mount and maintain and can be integrated with the building, various potential safety hazards are eliminated, utilization rate of the solar water heater is increased, and the novel black substance application and the novel application method can be widely applied to the field of solar water heaters.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization, in particular to a new application of black matter and a new application method thereof. Background technique [0002] Solar energy is one of the most important renewable energy sources that are inexhaustible, green, energy-saving and environmentally friendly. If solar collectors can achieve technological breakthroughs in terms of cost, life, and heat collection efficiency attenuation, solar energy will become a large-scale alternative energy. The black substance has a good solar light-to-heat conversion function and can absorb solar heat. One of the existing methods of use is to make the black substance into a solar absorbing coating, and the other is to make the black substance into a ceramic solar collector plate. The manufacturing cost of these two methods is relatively high, and the process is also relatively complicated, which will cause certain environmental pollution. It a...

The black substance has a good solar light-to-heat conversion function and can absorb solar heat. One of the existing methods of use is to make the black substance into a solar absorbing coating, and the other is to make the black substance into a ceramic solar collector plate. The manufacturing cost of these two methods is relatively high, and the process is also relatively complicated, which will cause certain environmental pollution, and it needs to be made by adding other materials, so that the effective content of black matter is reduced, thereby reducing the solar energy absorption rate.
