Description

Household solar vacuum tube cleaning equipment

Technical Field

The invention relates to the technical field of vacuum tubes, in particular to household solar vacuum tube cleaning equipment.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. The solar water heater is divided into a vacuum tube type solar water heater and a flat plate type solar water heater according to the structural form, mainly the vacuum tube type solar water heater is used as a main part, the vacuum tube type household solar water heater converts solar energy into heat energy and mainly depends on a vacuum heat collecting tube, the vacuum heat collecting tube utilizes the principle that hot water floats upwards and cold water sinks, the structure of the solar water heater is like an elongated thermos liner, and vacuum is formed between an inner layer and an outer layer. The surface of the inner glass tube is coated with a spectrum selective absorption coating by a special process for absorbing solar radiation energy to the maximum extent. After sunlight irradiation, photons impact the coating, solar energy is converted into heat energy, water absorbs heat from the outside of the coating, the water temperature rises, the density is reduced, hot water moves upwards, and cold water with high specific gravity falls. The hot water is always located in the upper part, i.e. the water tank. The relationship between the temperature rise condition of hot water in the solar water heater and the external temperature is not large, and the temperature rise condition mainly depends on illumination.

Due to various factors such as tap water quality, a large amount of scale can be generated inside the solar vacuum tube when the solar vacuum tube is used for a long time, the generation of the scale not only can cause the quality of water used by people to be reduced, but also leads to the deterioration of the light sensing effect of the vacuum tube, the reduction of the heat energy conversion efficiency of the solar water heater, the influence on the requirement of people on using hot water, the main component of the scale is calcium-magnesium compound, the use of the solar vacuum tube is influenced as the more the scale is accumulated, therefore, the solar vacuum tube needs to be cleaned frequently, but for household solar energy, most of the household solar energy is only to dissolve the water scale by using a dissolving agent, the water scale in the household solar energy cannot be cleaned deeply, the cleaning strength is not high enough, and because solar vacuum tube fragility is great, not allow to collide with, lead to being difficult to clear up stubborn spot on its inner wall, it is inconvenient not enough when people clear up the inner wall of solar vacuum tube.
