Problems solved by technology

[0007] The tower system is a solar drying system that uses a solar mirror as a heliostat and focuses multiple solar reflectors on a dryer. Due to the characteristics of tower solar energy collection, it makes use of part of the solar mirror's utilization time in tracking the solar process. It only takes 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 scale Larger, not suitable for small or home systems

Embodiment 1

[0063] Example 1: A fixed-point array solar drying system composed of 4 solar mirrors and 3 dryers

[0064] as attached figure 1 , 2 , The fixed-point array solar drying system composed of 4 solar mirrors and 3 dryers 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, solar mirrors 1, 2, and 3 focus the solar energy on the dryers 1, 2, and 3 respectively, realizing 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 dryers 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 3 In the afternoon, when the sun sets in the west, No. 1, 2, and 3 solar mirrors focus the solar energy on No. 2, 3, and No. 4 dryers respectively t...

Embodiment 2

[0065] Example 2: A fixed-point array solar drying system consisting of 12 solar mirrors and 6 dryers

[0066] This example Figure 4 The fixed-point array solar drying system composed of 12 solar mirrors and 6 dryers is shown. The 12 solar mirrors are arranged in an array of three rows and four columns, and the six dryers are arranged in an array of three rows and two columns. The devices are respectively arranged in the middle area of ​​the three rows of solar mirrors.

[0067] In different time periods in the morning, noon, and afternoon, solar mirrors 1-12 can choose different dryers 1-6 for focusing, and according to the actual solar energy collection efficiency, select different focus points for focusing, and are in different positions For solar mirrors No. 1-12, the choice of focusing dryers is also different. For No. 1, 5, 9, 4, 8, and 12 solar mirrors on both sides, there are 2 dryers that can be selected for focusing. For No. 2, 3, 10, and 11 solar mirrors in the m...

Embodiment 3

[0069] Embodiment 3: 1*3 parabolic fixed point array solar tracking drying system

[0070] as attached Figure 5As shown, this embodiment adopts three parabolic dish solar mirrors (2), which are arranged on a parabolic connecting part, and each solar mirror is provided with two rotating shafts, that is, the horizontal axis and the vertical axis. The horizontal axis and the vertical axis intersect perpendicularly to form a system axis, and each solar mirror is connected to a parabolic connecting part through a system axis. This embodiment consists of three system axes arranged on the connecting parts and a support connected to the ground The solar mirror bracket, the connecting parts do not move, but the three system axes move, the solar tracking control device is set to connect with each system axis, and physical and optical sensors are set on each solar mirror (2), the solar tracking control device is The integrated electronic control device composed of motor, transmission g...

Abstract

The invention relates to solar energy focusing utilization, in particular to a solar drying system which can be used for realizing solar energy collection by solar mirrors adopting dot focusing and is applied to the focusing and tracking of solar energy. The invention provides a fixed dot array solar drying system. The solar drying system comprises at least one solar mirror or one group of solar mirrors adopting dot focusing, at least one dryer and a tracking control device, wherein the solar mirrors are arranged on a solar mirror bracket, the dryers are arranged in a dotted region focused by the solar mirrors and arranged above or below the solar mirrors, and the focus lengths of the solar mirrors vary in the solar tracking process and are always kept in the dotted regions of the dryers; and the sunlight is focused by the solar mirrors to at least one dryer or a solar photo-thermal converter of the dryer under the control of the tracking control device when the sunlight varies, the dryers do not move with the solar mirrors in the solar tracking process of the solar mirrors, the dyers are kept static relative to the ground, and the tracking and focusing utilization of the solar energy is realized.

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 a point-focused converter to realize a solar focus tracking drying system, and to the focus and utilization of solar energy. Background technique [0002] Solar drying is to use solar drying equipment to dry industrial and agricultural by-products. We call it solar drying. [0003] Drying equipment is also called dryer and dryer. The equipment used for drying operation, by heating the moisture in the material (generally refers to water or other volatile liquid components) to vaporize and escape, so as to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, drying wood before making wooden molds and woodware can prevent product deformation, and drying ceramic blanks before calcination can prev...
