Description

Simple vacuum tube descaling device for solar water heater

Technical Field

The utility model relates to the field of solar water heaters, in particular to a simple vacuum tube descaling device of a solar water heater.

Background

The solar water heater is a heating device for converting solar energy into heat energy and heating water from low temperature to high temperature, and the main principle is that sunlight passes through a first layer of glass of a heat absorption pipe and irradiates onto a black heat absorption layer of a second layer of glass, the heat of the solar energy is absorbed, as the two layers of glass are in vacuum insulation, the heat transfer is greatly reduced, most of the heat can only be transferred to water in a glass pipe, the water in the glass pipe is heated, the heated water becomes lighter and enters a water tank upwards along a heating surface of the glass pipe, and the water with relatively low temperature in the water tank enters the glass pipe for supplementation along a backlight surface of the glass pipe, so that the water in the water tank is continuously heated, and hot water is obtained.

After the solar water heater is used for a period of time, the heat exchange efficiency between the heat absorption coating in the vacuum tube and water is greatly reduced, because impurities in tap water become scale to be accumulated on the inner wall of the solar vacuum tube after being heated, when the scale is accumulated to a certain degree, the heat exchange efficiency between the heat absorption coating and water is reduced, when the scale is too thick, the heat absorption coating on the solar vacuum tube cannot timely and outwards emit due to heat, and in a high-temperature state for a long time, the heat absorption coating can fall off, so that the heat collection efficiency and the service life of the vacuum tube are influenced. The common descaling method is to detach the vacuum tube, soak the vacuum tube with acetic acid, and then brush the vacuum tube one by one with a brush.

Chinese patent CN112097402a discloses a solar water heater with self-cleaning function for scale of vacuum tube, comprising a water tank and a base, a vacuum tube arranged between the water tank and the base, a cavity communicated with the vacuum tube arranged in the base, a vent hole arranged on the water tank, a cleaning mechanism and a pushing mechanism, wherein the cleaning mechanism comprises a cleaning member movably arranged in the vacuum tube, a baffle ring fixed at the joint of the water tank and the vacuum tube, an elastic member arranged between the cleaning member and the baffle ring, and a push rod fixedly connected with the cleaning member, and the other end of the push rod extends into the cavity; the push rod mechanism comprises a push plate, a first telescopic airbag fixedly connected with the push plate and a second telescopic airbag arranged in the first telescopic airbag, a liquid storage cavity is formed between the first telescopic airbag and the second telescopic airbag, low-boiling-point evaporating liquid is arranged in the liquid storage cavity, an air duct communicated with an exhaust hole is arranged on the second telescopic airbag, and the push plate is abutted to the push rod. The utility model can remove scale, but the cleaning mechanism is arranged in the vacuum tube, because the vacuum tube is smaller, and the heating is carried out by utilizing the principle that hot water naturally upwards and cold water naturally downwards, if the cleaning mechanism is arranged in the vacuum tube, on the one hand, the cost is relatively high, and on the other hand, a certain resistance is generated on the flow of cold water and hot water, so that a certain influence is generated on the heating rate.
