Embodiment 1

[0034] A temperature concentration gradient spiral baffle storage tank, such as figure 1 As shown, it includes a tank body, more than one helical baffle plate 4 that is evenly distributed in the vertical direction of the tank body and has closed edges, an inlet and outlet pipe group and an instrument interface group.

[0035] The tank body includes a cylindrical cylinder body 1, an upper head 2 and a lower head 3; the upper head 1 and the lower head 2 are respectively welded and connected to the upper and lower end surfaces of the cylinder 1; The upper head 2 is an elliptical hemispherical head; the lower head 3 is a flat head under low pressure conditions, and an elliptical hemispherical head under high pressure conditions.

[0036] Such as figure 2 As shown, the spiral baffle 4 is divided into a fan-shaped area 5 and two triangular areas 6, wherein the fan-shaped area 5 is determined by the inner diameter of the cylinder 1, the inclination angle and the fraction of the spi...

Abstract

The invention discloses a temperature and concentration gradient spiral baffle plate storage tank and application. The temperature and concentration gradient spiral baffle plate storage tank mainly comprises a tank body, more than one spiral baffle plates arranged in the tank body, an inlet and outlet pipe group arranged on the outer wall of the tank body, and an instrument interface group. The spiral baffle plates are divided into a fan-shaped area and two triangular areas, the fan-shaped area is a fan shape of an ellipse which is symmetrical about a short axis and is determined by the innerdiameter of the tank body, the inclination angle and the fraction of the spiral baffle plates, and the triangular areas are bent to different directions from two straight edges of the fan-shaped area;the shape of each triangular area can just block half of a triangular notch formed between the fan-shaped areas of every two adjacent spiral baffle plates; the adjacent spiral baffle plates are connected end to end in the triangular areas and are fixed through spot welding; and a quasi-spiral line is formed at the outer edge, is attached to the inner wall of the tank body, and is fixed through intermittent spot welding. On the basis that the space of the storage tank is effectively utilized, the stable distribution and energy storage functions of temperature gradient concentration are achieved, the cost is reduced, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of energy storage tanks, in particular to a temperature concentration gradient spiral baffle storage tank and its application. Background technique [0002] Solar high-temperature power generation involves the inconsistency between the period of receiving solar energy and the period of electricity consumption, so the unit needs to have the function of energy storage. The traditional solution requires at least two saline solution storage tanks, high temperature and low temperature. In recent years, the research and development of nuclear power peak shaving units has been put on the agenda. If the traditional method of evaporating and separating the displaced boric acid solution is still used, the economy will be greatly reduced, and the double storage tank solution obviously has the disadvantage of bulkiness. Absorption refrigerator solution energy storage is also a solution that uses solar energy to pretrea...
