Problems solved by technology

In this type of structure, the heat generated by the converging light energy of the light concentrating device will be lost in a large amount during the process of being transferred to the heating tube, resulting in low efficiency of the entire heating device and affecting the heating effect
In addition, solar steam power generation using solar water heating devices is becoming more and more popular, but the traditional solar steam power generation system cannot cooperate well with the solar heating part in auxiliary heating, steam recovery and other links, resulting in energy utilization. Low efficiency, can not make full use of light and heat resources, still needs to be improved

Abstract

The invention relates to a solar heating device and a solar steam generating system utilizing the solar heating device. The solar heating device comprises a metal water supply pipe with a water inlet and a water outlet, the metal water supply pipe is provided with a recessed portion recessed towards an inner cavity of the pipe, and a focusing device which can focus sunlight and enables the focusing light to be converged into the recessed portion through an opening of the recessed portion is arranged outside the metal water supply pipe. By arranging the recessed portion on the metal water supply pipe, the heat absorption ability of the metal water supply pipe is greatly improved, and accordingly the photothermal utilizing efficiency of the heating device and the steam generating system is improved. By arranging burning auxiliary heating, the ability of the steam generating system adapting to external condition changes is enhanced. By arranging a plurality of waste heat recycling structures, the heat utilizing efficiency of the steam generating system is further improved.

Description

[0001] technical field [0002] The invention relates to a solar heating device and a solar steam power generation device utilizing the solar heating device. Background technique [0003] Existing concentrating solar water heating devices usually include a lens or mirror concentrating device for concentrating sunlight, and a heating pipe for absorbing heat and heating the passing water flow. In this type of structure, a large amount of heat generated by the converging light energy of the light concentrating device will be lost in the process of being transferred to the heating tube, resulting in low efficiency of the entire heating device and affecting the heating effect. In addition, solar steam power generation using solar water heating devices is becoming more and more popular, but the traditional solar steam power generation system cannot cooperate well with the solar heating part in auxiliary heating, steam recovery and other links, resulting in energy utilization.
