Problems solved by technology

[0009] The tower system is a solar seawater desalination system that uses a solar mirror as a heliostat and focuses multiple solar mirrors on a seawater desalination device. The use time is only 4-6 hours. For example, the solar mirror on the east side of the tower is basically unusable in the morning, and can only be used after noon or afternoon, so the efficiency of solar energy collection is low. This technical solution can achieve high temperature collection, but usually Its large size is not suitable for small or home systems

Embodiment 1

[0068] Example 1: Fixed-point array solar desalination system composed of 4 solar mirrors and 3 seawater desalination devices

[0069] as attached figure 1 , 2 , The fixed-point array solar seawater desalination system composed of 4 solar mirrors and 3 seawater desalination devices shown in 3, figure 1 , 2 , 3 are the collection and utilization of solar energy in the morning, noon and afternoon respectively, figure 1 In the morning, the sun rises from the east, and No. 1, 2, and 3 solar mirrors focus the solar energy on No. 1, 2, and 3 seawater desalination devices respectively to realize the tracking and focusing of solar energy; figure 2 At noon, the sun is located in the central area of ​​the sky, No. 1 and No. 4 solar mirrors focus the solar energy on No. 1 and No. 3 seawater desalination devices respectively, and No. 2 and No. 3 sunglasses focus on No. 2 solar storage equipment to realize the tracking and focusing of solar energy; image 3In the afternoon, when the s...

Embodiment 2

[0070] Embodiment 2: Fixed-point array solar desalination system composed of 12 solar mirrors and 6 seawater desalination devices

[0071] This example Figure 4 The fixed-point array solar desalination system composed of 12 solar mirrors and 6 seawater desalination devices is shown. The 12 solar mirrors are arranged in an array of three rows and four columns, and the six seawater desalination devices are arranged in an array of three rows and two columns. Arrangement, seawater desalination devices are respectively arranged in the middle area of ​​the three rows of solar mirrors.

[0072] In the different time periods of morning, noon, and afternoon, solar mirrors 1-12 can choose different seawater desalination devices from 1-6 to focus. For solar mirrors No. 1-12 in the position, the selection of desalination devices that can be focused is also different. For solar mirrors No. 1, 5, 9, 4, 8, and 12 on both sides, there are 2 desalination devices to choose from For focusing,...

Abstract

The invention relates to focusing of solar energy, and in particular relates to a solar-powered seawater desalination system which collects solar energy by means of point focusing solar energy mirrors and is applied to focusing tracking solar energy. The invention provides the solar-powered seawater desalination system in a fixed point array. The system comprises at least one or one group of point focusing solar energy mirrors, at least one seawater desalination device and a tracking control device. The solar energy mirrors are arranged on a solar energy bracket, and the seawater desalination device is arranged in a pointy area focused by the solar energy mirrors. The focal length of the solar energy mirrors in the process of tracking solar energy changes and is always maintained in the pointy area of the seawater desalination device. The tracking control device controls the solar energy mirrors to focus sunlight to at least one seawater desalination device when sunlight changes. The seawater desalination devices do not move with the solar energy mirrors in the process of tracking solar energy by the solar energy mirrors, and the seawater desalination devices are stationary relative to the ground, so that solar energy is tracked and focused.

Description

technical field [0001] The invention relates to the utilization of solar energy, in particular to the use of a point-focused solar mirror to realize solar energy collection, and the use of a point-focused converter to realize the focus tracking seawater desalination system of solar energy, and relates to the focus and utilization of solar energy. Background technique [0002] Solar desalination is a device that uses solar energy to desalinate seawater. [0003] As of 1990, the water production capacity of installed seawater desalination plants in the world was 13,000,000 cubic meters per day. By 2000, that number had doubled. The rapid increase of desalinated water will cause a series of problems, the most prominent of which is the problem of energy consumption. It is estimated that the production of 13,000,000 cubic meters of desalinated water per day requires the consumption of crude oil I. 300 million tons. Even if people can afford the fuel, the global greenhouse eff...
