Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 The solar pool-collector composite drying system shown. Considering the thermal insulation and construction cost of the solar pond, the solar pond is built below the surface; the drying chamber 9 is built 3 meters above the ground, and the inside of the drying chamber 9 is equipped with a mesh partition 7 for putting materials. It is a transparent glass plate 8 with the same inclination angle as the local latitude. If the material needs to be protected from direct sunlight, the glass plate can be covered with a layer of shade net; a solar collector 6 is installed between the solar pool 1 and the drying room 9, To make full use of solar energy. One end of the heating heat exchange copper pipe 3 is connected to the air duct 4 and the other end is connected to the solar heat collector 6 .

Abstract

The invention relates to a solar pond composite drying system. The system comprises a salt gradient solar pond, wherein an upper layer of the salt gradient solar pond is an upper convection layer which consists of clear water, a lower layer of the salt gradient solar pond is a lower convection layer, namely a heat storage layer, which consists of saturated salt solution, and a middle layer of the salt gradient solar pond is a non-convection layer, namely a gradient layer. A porous heat absorption dielectric layer is arranged in the heat storage layer of the salt gradient solar pond. Waste boiler slag is used as a heat absorption dielectric in the porous heat absorption dielectric layer. In order to enhance a heat absorption effect, the waste boiler slag is laid at the bottom of the solar pond to serve as the heat absorption dielectric. The solar pond has functions of a heat collector and a heat storage device; the system has a simple structure and is low in manufacturing cost; heat can be stored for a long time (extraseasonally); and a low-temperature heat source with stable performance can be provided all year around. Through the system, the problem of serious influence of changes of weather on a heat collector-greenhouse type solar dryer is solved, solar energy is fully utilized, and drying efficiency is increased.

Description

technical field [0001] The invention relates to a solar energy storage drying system, in particular to a clean and pollution-free solar energy storage utilization device. Background technique [0002] In today's world, energy issues have become more and more important. How to make better use of resources and develop new energy utilization methods has become the trend of the times. Solar energy has the advantages of inexhaustible sources, clean and pollution-free, and can be applied in many fields. There are a variety of solar dryers on the market, including greenhouse solar dryers, collector solar dryers, collector-greenhouse solar dryers, integrated solar dryers, and solar far-infrared dryers. Generally speaking, the biggest problem is that it is greatly affected by the weather and the efficiency is not high. [0003] The currently published patents mainly include: Patent No. CN200920090974.8, heat collector-greenhouse type solar dryer, patent No. CN200720058640.3, regene...
