Solar multi-directional tracking solar energy drying equipment

Abstract

The invention discloses solar multi-directional tracking solar energy drying equipment. In the equipment, one or a group of solar linear focusing optical mirrors comprising a plurality of reflecting mirrors, a Fresnel mirror, a plane mirror and the like is/are adopted; a revolving shaft of each mirror is arranged on a solar linear focusing optical mirror support; each solar optical mirror can rotate around the shaft, and meanwhile moves together with the solar mirror support, so that the tracking of the solar energy can be realized by the multi-directional tracking consisting of rotating around the shaft and moving together with the solar mirror support; and as the solar energy drying equipment is arranged in a cylinder interval on ground or a building, when the solar mirror moves, the solar energy drying equipment can keep still, the focal length is variable zooming and tracking, and the solar energy drying equipment realizes the drying utilization of the focused and tracked solar energy in a cylinder. The invention provides an array structure of the equipment, which is suitable for systems of different scales, and simultaneously suitable for large-scale utilization of the solar energy drying equipment.

Description

technical field [0001] The invention relates to the utilization of solar energy, especially the multi-directional solar drying equipment composed of linear tracking with focus tracking of solar energy and array tracking. Background technique [0002] At present, there are many forms of solar drying devices, which can be roughly divided into: greenhouse type, heat collector type, combination type of heat collector and greenhouse, integral type and parabolic concentrating type, etc. Among them, the heat collection system of the concentrating solar drying device is generally composed of a cylindrical parabolic concentrating heat collector, which is a medium temperature solar drying device, but the structure of this drying device is complicated and the cost is high. Although the investment of simple solar drying is small, the capacity is small and the thermal efficiency is low; while the large and medium-sized ones require large investment and occupy a large area, and the proble...

[0005] Chinese patent 200710176966 provides a combined tracking system, which can be used in a trough-type and tower-type tracking system. The tracking method adopts the method of keeping the focus fixed while the solar mirror system moves. It is mainly set on the ground. Two orbits are used for tracking, and the line-focusing system of the trough system uses its linear axis to be placed parallel to the axis of the earth's self-propagation, so it can use rotation in one direction to achieve tracking, but this scheme uses rotation on the ground to achieve trough
