Problems solved by technology

[0009] The tower system is a seawater desalination device that uses a solar mirror as a heliostat and focuses multiple solar mirrors on a seawater desalination device. Due to the characteristics of tower solar energy collection, it makes use of part of the solar mirror in tracking the solar process The 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 other Large scale, not suitable for small or home systems

Embodiment 1

[0074] Embodiment 1: A mobile point array solar energy collection and utilization system composed of 4 solar mirrors and 2 solar energy utilization devices

[0075] as attached figure 1 , 2 , 3 shown in the mobile point array solar collection and utilization system composed of 4 solar mirrors and 2 seawater desalination devices, figure 1 , 2 , 3 are the collection and utilization of solar energy in the morning, noon and afternoon respectively, figure 1 In the middle of the morning, the sun rises from the east. No. 1, 2 and 3 solar mirrors focus the solar energy on No. 1 and No. 2 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. 2 solar mirrors focus the solar energy on the No. 1 seawater desalination device respectively, and No. 3 and 4 solar mirrors focus on the No. 2 solar storage device to realize the tracking and focusing of solar energy;...

Embodiment 2

[0076] Embodiment 2: A moving point array solar energy collection and utilization system composed of 12 solar mirrors and 6 solar energy utilization devices

[0077] This example Figure 4 The mobile point array solar collection and utilization system consisting 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.

[0078] 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 desali...

Embodiment 3

[0081] Embodiment 3: 1*3 moving point solar energy tracking utilization system

[0082] as attached Figure 5 As shown, this embodiment adopts three parabolic dish solar mirrors (2), which are arranged on a parabolic connecting part, and each solar mirror is connected to the parabolic connecting part through a system axis, and the horizontal axis of the system axis The axis and the longitudinal axis are perpendicular to each other. This embodiment is a solar mirror bracket composed of three system axes arranged on the connecting parts. The connecting parts do not move, but the three system axes move. connection, set physical and optical sensors on each solar mirror (2), the solar tracking control device is an integrated electronic control device composed of motor, transmission gear and electronic control part, and adopts a tracking system that complements physical and optical tracking to realize tracking Solar energy tracking, at the same time, the seawater desalination devic...

Abstract

The invention relates to solar energy utilization, and particularly relates to a moving point array solar-powered seawater desalination system which realizes the collection of solar energy by using point-focusing solar mirrors. The system disclosed by the invention at least comprises one or a set of point-focusing solar mirrors, at least one seawater desalination device and a tracking control device, wherein the solar mirrors are arranged on a solar mirror bracket, the seawater desalination device is arranged a seawater desalination device bracket, the seawater desalination device is arranged in focused punctiform areas of the solar mirrors and arranged above or below the solar mirrors; the tracking control device controls the solar mirrors to focus sunlight to the at least one seawater desalination device when the sunlight is changed, then in the process that the solar mirrors track the solar energy, the seawater desalination device moves, and each or each set of solar mirrors selects a seawater desalination device which can reach the highest solar energy utilization efficiency to carry out focusing, thereby realizing the tracking and focusing utilization of solar energy.

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, the use of solar point focus to realize a focus tracking seawater desalination device for solar energy, and 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 effect, air pollution, etc....
