Problems solved by technology

In this type of structure, there is no control when the water pump enters the water volume, and the water volume is often too large, resulting in slow heat absorption and temperature rise, low heat energy absorption rate, and insufficient vapor-liquid phase transition, which makes it difficult to meet the steam requirements of different industrial production equipment

Abstract

The invention relates to a distributed all-weather solar steam unit. The solar steam unit consists of soft water equipment, a circulation pump, a temperature-controlled flow valve, a solar vacuum tube, a U-shaped tube, a U-shaped tube jet atomization connection device, a thermal insulation tank, and an auxiliary heating unit. Device structure; the invention is a distributed all-weather solar steam unit, through the auxiliary heating device, the steam boiler can be replaced, the boiler room and the fireman are eliminated, the centralized steam supply mode of the boiler is changed, and the terminal is turned on immediately. Solar steam can also be used to drive low-boiling-point organic medium to vaporize and expand, to push the expander to output mechanical energy to generate electricity, and to use the organic medium to cool down and generate hot water to realize efficient cogeneration of solar steam. At the same time, the present invention uses an ordinary solar vacuum tube collector as a carrier , developed the rooftop solar steam energy, which can be used locally to amplify the energy-saving effect. It has the characteristics of mature products, simple structure, convenient operation and strong practicability.

Description

technical field [0001] The invention relates to a distributed all-weather solar steam unit, which belongs to the technical field of industrial application of solar steam. Background technique [0002] At present, the use of vacuum solar tubes to generate electricity using solar energy has attracted more and more attention. On the one hand, its use saves energy and maximizes the use of heat generated by energy. On the other hand, it can also make full use of Solar energy is a clean and environmentally friendly energy source. However, due to the unavoidable large heat loss in the process of solar heat conduction, the heat collection temperature of the vacuum tube is not high, and there is a shortcoming of low heat energy utilization rate and inability to make full use of resources. [0003] And the existing solar steam device usually includes soft water device, solar thermal collector and steam transmission device. In this type of structure, the pump lacks control when input...
