Embodiment Construction

[0034] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0035] like figure 1 As shown, an energy storage tank with a built-in prefabricated concrete heat storage body includes a tank body 1, a base 13, a prefabricated concrete heat storage body 2, a heat transfer oil 6, and a mesh cage arranged on the periphery of the prefabricated concrete heat storage body 2 3. The tank body 1 is set on the base 13, the precast concrete heat storage body 2 is set in the tank body 1, and the heat transfer oil 6 is submerged in the precast concrete heat storage body 2.

[0036] Said tank body 1 comprises an upper cover 11 and a tank body body 12, and the upper end of the upper cover 11 and the tank body body 12 are tightly connected by bolts. The upper cover 11 is provided with a thermal oil inlet pipe 14 connected with the solar heat collector, a heat transfer oil outlet...

Abstract

The invention belongs to the technical field of solar energy storage, in particular to a built-in prefabricated concrete heat-storage body energy-storage tank. The built-in prefabricated concrete heat-storage body energy-storage tank includes a tank body, a prefabricated concrete heat-storage body, conduction oil and a cylinder mould which is arranged at the periphery of the prefabricated concreteheat-storage body, and the bottom of the tank body is in a round shape; the prefabricated concrete heat-storage body is arranged in the tank body, and the conduction oil is filled over the prefabricated concrete heat-storage body; and the upper of the tank body is provided with a hot oil inlet pipe which is connected with a solar energy collecting device and a guide hot oil outlet pipe which is connected with a vapor generator, and the lower of the tank body is provided with a cold oil outlet pipe which is connected with the solar energy collecting device and a cooling guide hot oil inlet pipe which is connected with the vapor generator. According to the built-in prefabricated concrete heat-storage body energy-storage tank, the prefabricated concrete heat storage body is used for storingthe solar energy, the heat energy is stored in the prefabricated concrete heat storage body, the usage amount of the conduction oil is reduced, the heat storage energy of the energy-storage tank is improved, the heat storage capacity is enlarged, and the use ratio of the solar energy is improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy storage, and in particular relates to an energy storage tank with a built-in prefabricated concrete heat storage body. Background technique [0002] The main means of solar thermal power generation include dish, tower, trough and linear Fresnel. The difference between different methods is mainly in the different forms of solar heat collection, and the basic physical process of power generation is basically the same, which is based on the light energy-electric energy process. The principle of solar thermoelectric technology is to use a solar concentrating system to reflect direct radiation to the surface of a central heat absorber, convert solar energy into thermal energy, and then store the thermal energy and generate electricity through a generator. [0003] Solar energy has the characteristics of intermittent and low heat flow, so it cannot generate power at night or on rainy days. At pre...
