Embodiment 1

[0016] Solar pool heating device, including reflector group 1, heat storage tank 2, heat-absorbing medium 3, circulation pump 4, heat exchanger 5; reflector group 1 is an array of 27 flat rectangular reflectors 6, each reflector The area of ​​the board 6 is 1 square meter; the horizontal installation position of the reflector group 1 is 1 meter northward from the edge of the heat storage tank 2, and the installation height is 1 meter above the surface of the heat storage tank 2; The light is reflected to the brine surface in the heat storage tank 2; the heat storage tank 2 is a trapezoidal pool structure, the north, east, and west side walls are all vertical planes at an angle of 90° to the horizontal, and the south side wall is at an angle of 60° to the horizontal The inclined surface of °, the bottom wall is a horizontal plane; the depth of the heat storage tank 2 is 2 meters; The heat absorbing medium 3 with a thickness of 0.2 meters is laid on the bottom wall, and the heat...

Embodiment 2

[0018] Embodiment 2: The device and air temperature conditions are the same as in Embodiment 1, and its nighttime work process includes the following steps: the circulation pump 4 continues to run uninterruptedly, the heated fluid water in the shell side of the heat exchanger 5 continues to circulate, and passes through the tube side of the absorption heat exchanger 5 The heat of the inner brine raises the temperature. When the device is in Taiyuan in July, it can provide heat for at least 1m every night 3 The heated fluid water rises from room temperature to above 50°C, and the water temperature can be maintained at 50.0-65.1°C by adjusting the flow rate of the heated fluid water, which can be used as domestic water.

Embodiment 3

[0019] Embodiment 3: The shape and structure of the device and the heating time conditions are the same as in Embodiment 1, the difference is that the heat storage tank 2 is an open container that is welded by steel plates and has a mineral wool insulation layer on the outside, and the shell of the heat exchanger 5 The heated fluid in process flow is biphenyl-biphenyl ether low-melting mixture type heat transfer oil. When the device is in December in winter, the temperature of the heat carrier oil circulating in the shell side of the heat exchanger can reach 80°C during the day and 65°C at night, and the heat can be used to heat domestic water, or directly used for domestic and Industrial heating.

Abstract

The invention provides a fast heating device of a solar pond. The fast heating device of the solar pond can achieve fast heat accumulation and temperature rising of saline water. The fast heating device of the solar pond comprises a reflector set, a heat accumulation pond, heat absorption media, a circulating pump and a heat exchanging device and the like. The heat accumulation pond can be a heat accumulation pond dug in the ground or a heat accumulation pond constructed with a container, and the surface of the heat accumulation pond can be covered by a nonopaque plastic or a glass plate. According to the fast heating device of the solar pond, a larger amount of sunlight is gathered in the heat accumulation pond by means of the reflector set in day time so that the temperature of the saline water in the pond can be increased to 75-95 DEG C quickly, and the heat of the saline water on the bottom of the pond is continuously transmitted to heated fluid through the heat exchanging device. The fast heating device of the solar pond can be widely used for extracting minerals from the saline water, desalination of the saline water or brackish water, and the like, and can also be used for heat supplying for industries and life of people. The fast heating device of the solar pond has the advantages that the structure is simple, heat accumulation efficiency is high, solar energy can be used quickly and conveniently, and the application prospect is broad.

Description

technical field [0001] The invention relates to solar heat collection, in particular to a solar pool rapid heating device that utilizes salt water to accumulate solar heat energy. Background technique [0002] The solar pond is a device that uses the concentration difference and density difference of salt water to automatically stratify and store solar heat energy. Because the grade of solar energy is relatively low and unstable, the heat storage capacity of the solar pool is limited to a certain extent. In most cases, when the ambient temperature is 25°C, the temperature of the brine in the solar pool can only be raised to about 45-60°C. There are also some reports that the brine temperature can be increased to above 90°C, but it is affected by specific operating conditions and ambient temperature, and often requires good insulation measures. Therefore, under normal circumstances, the heat supply capacity of the solar pond to the outside is maintained at a temperature lev...
