A large solar-powered vapor storage

Abstract

The invention relates to a solar steam storage, in particular to a large-sized solar steam storage. The large-sized solar steam storage comprises a vacuum tank, wherein a vacuum interlayer is formed between a vacuum tank casing and a vacuum tank lining; the vacuum interlayer is filled with a layer of heat insulation material; a main steam inlet pipe, a main steam outlet pipe and a main water outlet pipe are arranged on the vacuum tank; an aggregation connection sealing head and a plurality of steel energy storage cylinders are arranged in the vacuum tank; steam inlet pipes, steam outlet pipes and water outlet pipes are arranged on the steel energy storage cylinders; electromagnetic valves are arranged on the water outlet pipes; water level sensors are arranged at the end parts of the water outlet pipes, located in the steel energy storage cylinders; the main steam inlet pipe, the main steam outlet pipe and the main water outlet pipe are located at one end of the vacuum tank and fixed to the aggregation connection sealing head; the steam inlet pipes, the steam outlet pipes and the water outlet pipes on the steel energy storage cylinders are respectively communicated with the main steam inlet pipe, the main steam outlet pipe and the main water outlet pipe via the aggregation connection sealing head. With the adoption of separated arrangement of heat insulation and energy storage, the heat insulation effect is good, the manufacturing cost of the solar steam storage is greatly lowered, and the use is safe.

Description

technical field [0001] The invention relates to a solar steam storage device, in particular to a large-scale solar steam storage device. Background technique [0002] Solar energy is a kind of clean and pollution-free energy, and the development potential of machines and tools. 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 generated water vapor 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 for a long time, there has never been a solar steam storage device that can generate solar steam The steam generated by the device is well stored so that the inexhaustible solar steam can be stored or used in rainy weather, but the existing vacuum storage device cannot be applied to solar ste...

[0002] Solar energy is a kind of clean and pollution-free energy, and the development potential of machines and tools. 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 generated water vapor 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 for a long time, there has never been a solar steam storage device that can generate solar steam The steam generated by the device is well stored so that the inexhaustible solar steam can be stored or used in rainy weather, but the existing vacuum storage device cannot be applied to solar steam storage, and the existing vacuum storage The vacuum degree of the device is easy to lose, and the heat storage effect is not good. Therefore, the applicant invented a solar steam storage, using a storage cylinder with a vacuum interlayer as the solar steam storage, but there are still big problems in this storage , because on the one hand, it needs to have good heat insulation performance, and on the other hand, it also needs to bear the high pressure generated by the accumulation of water vapor, so the volume of this kind of storage will be greatly limited. When the water vapor storage When it is larger, if the volume of the reservoir is increased, firstly, the larger the volume, the worse the pressure bearing effect, which makes its production cost extremely high; secondly, when the volume of the reservoir is too large, the amount of water vapor stored in it will When too much, due to the continuous increase of internal pressure, the safety performance of the storage will be extremely low, and safety accidents will easily occur
