Solar energy storage and utilization device

Abstract

A solar energy storage and utilization device comprises a metal inner container, a collecting lens, an energy storage tank and a water storage tank. A transparent vacuum tube is arranged outside the metal inner container; the bottom of the water storage tank and the bottom of the metal inner container are communicated through a water pipe I, the upper portion in the metal inner container and the bottom of the water storage tank are connected through a steam pipe I, and an exhaust pipe and a water supplementing pipe are arranged on the energy storage tank. According to the solar energy storage and utilization device, the transparent vacuum tube layer is arranged outside the metal inner container, received solar energy is stopped from being lost and thus the utilization rate of solar energy is substantially increased; meanwhile, the water storage tank and the energy storage tank are arranged so that solar energy received in good weather is stored in the energy storage tank in the form of high temperature and high pressure water and utilized in bad weather, the situation that an existing solar energy utilization device depends a lot on weather conditions is eliminated, and the application range of the solar energy utilization device is widened.

Description

technical field [0001] The invention relates to a device for generating steam by using solar energy, in particular to a solar energy storage and utilization device. Background technique [0002] Solar energy is a clean and pollution-free energy source with great development potential. With the increasing use of solar energy, the development of solar energy devices is becoming more and more mature, such as solar steam generators. Solar steam generators are devices specially used to produce water vapor , the water vapor produced can be used for heating in winter, cooking food, storage, etc., because of its convenient use and low cost, it has been widely welcomed by consumers in recent years, but the existing solar steam generators are too dependent on sunlight That is to say, it must be used when the weather is good, but it cannot be used on cloudy days or at night, and when the sun is sufficient, due to the high temperature, a large amount of solar energy can be collected in ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of low utilization efficiency and heavy dependence on weather conditions existing in existing solar energy utilization devices, the present invention provides a solar energy storage utilization device, which can store the energy collected when the solar energy is sufficient, and use it when the solar energy is insufficient , thereby improving the utilization efficiency of solar energy, and the generated solar steam has high temperature and good quality, which can well meet the requirements of consumers
