Example Embodiment

[0020] The invention provides a heat supply device and a heat supply method for solar anti-gravity natural circulation. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 Schematic diagram of the structure of the heating device for solar anti-gravity natural circulation. The device is provided with a heat collecting plate 1, the heat collecting plate 1 is connected with the evaporator 2, the output end of the evaporator 2 is connected with the condenser 3 through the first pipe 8, and the second pipe 9 output by the condenser 3 is connected with the liquid collecting tank 4-phase connection. Wherein, the solar heat collector 1 collects solar energy to promote the evaporation of the liquid in the evaporator 2 . The evaporation upper chamber 6 of the evaporator 2 is made of a porous structure material, which has a lyophilicity and a large specific surface area. The purpose is to facili...

Abstract

The invention discloses a heating device and method for solar antigravity natural circulation and belongs to the technical field of solar energy heat utilization. The heating device is mainly composed of a heat collecting board, an evaporator, a condenser, a semipermeable membrane pipe and the like. A capillary core of a porous structure is arranged at the upper portion of the evaporator and the lower portion of the evaporator is connected with the semipermeable membrane pipe arranged in a liquid collection tank. Before work, a saline solution with certain concentration is injected in an evaporation cavity and the semipermeable membrane pipe; when solar energy is collected through the solar heat collecting board, the temperature of the capillary core in the evaporator is increased, liquid evaporates, generated steam is condensed, heat is released, and low-concentration liquid generated through condensation flows into the liquid collection tank. The osmotic pressure difference generated by the concentration difference is used for achieving antigravity natural circulation heat supply, and liquid circulation does not need to be maintained through a vacuum pump or a circulating pump. The heating device is simple in structure and convenient to operate, heat efficiency is improved, cost is reduced, and a good means and the method are provided for further utilization of solar energy.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a heat supply device and a heat supply method for solar energy antigravity natural circulation. A solar heat utilization device that realizes anti-gravity natural circulation heating. Background technique [0002] With the development of science and technology, great progress has been made in solar energy, energy-saving technology and heating. Try to provide the best quality resources. Solar energy is a kind of clean energy, and has the advantages of universality, hugeness and inexhaustibility, so it has broad development and utilization prospects. In recent years, with the development of solar technology, people have begun to widely use solar heating. But the current technical cost is still relatively high, and the system is relatively complicated. Compared with traditional solar heating, the use of solar anti-gravity natural circulation technology...
