Problems solved by technology

Most people who use solar water heaters do not have a strong awareness of the cleaning and cleaning of solar vacuum tubes, and they lack knowledge; another point is to regularly clean high-rise solar vacuum tubes, which is a heavy task and labor-intensive.
All of these have led to the reduction of the absorption efficiency of the vacuum tube of the solar collector, and the heat collection efficiency is greatly reduced.
Through experiments, the decline rate of heat collection efficiency is about 10% to 70%.
Therefore, it has seriously affected the hot water supply of residents and wasted resources.

Abstract

The invention relates to a rainwater water-saving cleaning system for a vacuum tube of a solar water heater, and belongs to the technical field of solar heating. The system comprises a sedimentation tank, a drain tube, a water outlet tube, a ball valve, a booster pump, a filter, a cleaning electromagnetic valve, a tubular cleaning nozzle and a system switch control circuit, wherein the sedimentation tank is arranged at the position lower than the surface of a roof and is connected with a drain opening on the surface of the roof through a water conduit; the water outlet tube arranged on the middle part of the sedimentation tank is connected with the tubular cleaning nozzle which is fixedly sleeved on a vacuum heat collecting tube through the ball valve, the booster pump, the filter and the cleaning electromagnetic valve; a booster motor is controlled by an alternating current contactor coil; and a photoelectric liquid level is connected with the input terminal of a programmable logic controller (PLC). The system has the advantages of cleaning a high-level solar vacuum tube regularly by utilizing rainwater, saving energy and water, improving heat collection efficiency of a solar heat collector and the like.

Description

technical field [0001] The invention relates to a solar water heater vacuum tube rainwater saving water cleaning system, which belongs to the technical field of solar heating. Background technique [0002] For a long time, since high-rise solar water heaters are installed on the roof and used for a long time, the outer wall of the solar collector vacuum tube will inevitably be polluted by dust or impurities. For cities with poor air environment, this phenomenon is even more serious; in addition, it is understood that, The temperature rise of hot water in solar water heaters has little to do with the outside temperature, but mainly depends on the light. Most people who use solar water heaters have little awareness and lack of knowledge about the cleaning and cleaning of solar vacuum tubes. Another point is to regularly clean high-rise solar vacuum tubes, which is a heavy task and labor-intensive. These have all led to the reduction of the absorption efficiency of the vacuum ...
