A kind of solar heat collecting device and its sewage treatment method

Abstract

The invention provides a solar heat collecting device and a sewage treatment method thereof, comprising a reflector, the reflector is divided into two parts along the middle part, namely the first part and the second part, and the supporting member is arranged at the lower part of the heat collecting pipe box , two hydraulic telescopic rods protrude from the supporting column and extend to connect the first part and the second part; they are used to drive the first part and the second part to separate or merge; when the first part and the second part are combined together, the The reflecting mirror constitutes a complete reflecting mirror, and the heat collecting tube box is located at the focal point of the reflecting mirror for collecting heat on the heat collecting tube box; when the first part and the second part are separated, the heat collecting tube box does not The focus of the first part and the second part does not collect heat on the heat collecting tube box. The invention proposes a heat collecting device with a new structure, and the vibration and descaling of the heat collecting device can be realized by whether to collect heat on the heat collecting device.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar heat collector system. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The total amount of solar radiation energy received by the earth's s...

AI Technical Summary

Problems solved by technology

[0007] In the modernization of the city, industrial development plays an extremely important role. However, with the rapid development of industry, the environmental problems caused by industrial sewage have also attracted people's attention. These sewage contain more heavy metal ions. Before the treatment, simple desalination treatment should be carried out, and the sewage with high heavy metal ion content should be subjected to simple ion precipitation treatment, which is convenient for systematic treatment in the later stage. Some devices on the market have some defects and cannot solve the sewage sedimentation well. The discharge of sediments such as residual sludge impurities in the sewage can not efficiently separate the metal ions in the sewage, and cannot meet the requirements of modern sewage treatment
