Water pump pumping irrigation system driven by utilizing solar steam and application method thereof

Abstract

The invention discloses a water pump pumping irrigation system driven by utilizing solar steam and an application method thereof. The invention aims to provide a system for converting solar photo-thermal energy into steam energy and directly driving the water pump to pump water for irrigation; according to the technical scheme, a heat collecting device is used for collecting solar energy and heating a heat transfer medium, a conveying pipeline is provided with a circulating pump, the circulating pump is used for conveying the heat transfer medium heated by the heat collecting device to a steamgenerator, and the heat transfer medium which has completed heat exchange in the steam generator is conveyed back to the heat collecting device; and the steam generator is used for absorbing heat carried by the heat transfer medium and heating the supplied water into steam for outputting, an energy accumulator is used for storing redundant steam generated by the steam generator, the water pump isused for driving the steam generated by the steam generator to act as a power to drive the water pump to run so as to carry out pumping irrigation operation. The system and the method are applicableto the technical field of solar energy utilization.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, in particular to a water pump lifting irrigation system driven by solar steam and an application method thereof. Background technique [0002] Since there are no power lines in poor mountainous areas or inaccessible islands, people mainly use solar photovoltaic power generation to drive water pumps for water supply. However, the conversion efficiency of photovoltaic equipment is much lower than that of photothermal equipment. The conversion efficiency of photovoltaic equipment is usually 10. -15%. At the same time, photovoltaic equipment is expensive. Therefore, comprehensively, the efficiency and cost of utilizing light and heat are more cost-effective than photovoltaic equipment. Contents of the invention [0003] The purpose of the present invention is to provide a system for converting solar heat into steam energy and directly driving a water pump for lifting and irrigation...
