Vacuum tube type modularized heat storage solar boiler

Abstract

The invention discloses a vacuum tube type modularized heat storage solar boiler which comprises a solar heat collector and a heat storage container. The heat storage container is formed by connecting a plurality of vacuum tubes in parallel or in series or in parallel and series. The heat storage container and the solar heat collector are connected through a pipeline to form a circulating system. A pump is arranged between the heat storage container and the solar heat collector. The heat storage container is provided with an air exhaust valve and a sewage draining exit. The vacuum tube type modularized heat storage solar boiler has the beneficial effects that the heat storage container is composed of modularized vacuum tube arrays, distributed heat storage is achieved, and the volume can be adjusted as needed; the cost of the vacuum type array type heat storage container is far lower than that of an original steam pocket, the size is small, the requirement for the level of pressure resistance is low, even small factories can achieve machining conveniently, and the solar boiler is suitable for homes or small work places.

Description

technical field [0001] The invention relates to a solar medium-temperature boiler suitable for high-efficiency operation at 150-400°C for solar heat utilization, which is formed by connecting multiple sets of vacuum tubes in parallel, can withstand relatively high pressure, and is small in size, and can use liquid or gas as its heat storage and boiler. heat transfer medium. Background technique [0002] Solar energy is an inexhaustible renewable energy source. Today, as fossil fuels are decreasing year by year and the international energy situation is becoming increasingly severe, the development and utilization of solar energy is one of the important ways to realize the diversification of energy supply and ensure energy security. [0003] A solar boiler is a steam generating system that uses solar energy to heat a fluid. Solar boiler consists of three parts, solar collector, steam drum, control system. At present, most solar boilers are placed indoors. The outer insulatio...

AI Technical Summary

Problems solved by technology

At present, most solar boilers are placed indoors. The outer insulation layer of the boiler is made of traditional organic and inorganic materials. It is not convenient for ordinary small factories to process this kind of boiler. Moreover, the maintenance of this heat storage tank is very inconvenient, and it is easy to cause fiber pollution. Due to the bulky size, high cost, and high requirements for pressure resistance, this kind of boiler adopts centralized heat storage, which is more suitable for large factories or schools, but not suitable for families or small units.
