Embodiment Construction

[0021] Attached below figure 1 , 2 The present invention is described further:

[0022] A superconducting solar heat pump drying system is composed of a superconducting solar heat collector 1, a drying oven 2, a superconducting waste heat recovery device 3, a waste heat source heat pump 4, and air ducts 15 and 36, and is characterized in that the superconducting solar heat collector 1 consists of a horizontal header 6, several superconducting heat transfer tubes 7 connected to the horizontal header 6, and an axial flow fan 8 installed in the horizontal header 6. Arc-shaped heat transfer fins 5 are welded below each superconducting heat transfer tube 7. The inner wall of the liner 14 is in close contact, and the back of the vacuum glass tube 9 is equipped with a groove-shaped flashlight plate 10. The groove-shaped concentrating plate 10 can focus the solar radiation light on the selective coating 11 on the outer wall of the inner liner 14 of the vacuum glass tube 9 in the for...

Abstract

A superconductive solar heat pump drying system is composed of a superconductive solar heat collector, a drying box, a superconductive waste heat recovering device, a waste heat source heat pump and an air flue. The superconductive solar heat pump drying system is characterized in that the superconductive solar heat collector, the drying box, the waste heat source heat pump and the superconductivewaste heat recovering device are communicated integrally through the air flue to form a material drying system with efficient heat collection, heat exchange and waste heat usage functions. The systemis capable of fully using solar radiation heat, large in temperature rise and heat value, high in material drying speed, environmentally friendly, sanitary and high in material drying quality, and compared with common solar drying equipment, the working efficiency is improved by 35% and is improved by 30% under the conditions of unstable illumination clearance and sunlight.

Description

technical field [0001] The invention relates to a solar drying system, in particular to a high-efficiency superconducting solar heat pump drying system. Background technique [0002] Solar drying is a drying method that uses the inexhaustible solar radiation heat energy to evaporate and remove the moisture in the material. [0003] Drying of industrial and agricultural products is the most energy-intensive process. It takes 1.2 tons of coal to dry 1 ton of jujube, 2 tons of coal to dry 1 ton of tobacco leaves, and 0.8 tons of coal to dry 1 ton of grain. The use of solar drying equipment for drying can not only save fuel such as non-renewable energy such as coal, oil, and gas, but also be clean and hygienic. It can effectively increase the temperature of the drying medium and ensure the drying quality of materials. However, it is not easy to effectively use solar energy for drying. Conventional solar drying equipment has the disadvantages of slow drying speed due to large so...
