Abstract

The invention provides a pressure difference descaling method for a heat collecting device. The method comprises the following steps of arranging an electric heater in a heat collecting tube box, operating the electric heater at night, extracting pressure data by a controller according to a time sequence, obtaining the pressure difference or the accumulation of the pressure difference change through the comparison of the pressure data in adjacent time periods, and when the pressure difference or the accumulation of the pressure difference change is lower than a threshold value, controlling the electric heater by the controller to stop heating or continue heating. Through the operation of the electric heater, a heat collecting tube continuously vibrates according to the pressure difference data, so that the descaling work is carried out.

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...
