Problems solved by technology

On February 20, 2009, Hu Wenbiao, the former chairman of Yancheng Biaoxin Chemical Co., Ltd., and Ding Yuesheng, the production director and workshop director, knew that the potassium salt wastewater produced in the production of chloroether ketone contained toxic and harmful substances. Discharging a large amount of potassium salt wastewater into the river caused serious water pollution, causing more than 200,000 residents in Yancheng City to stop drinking water for 66 hours and 40 minutes, causing huge losses
Miao Tongchun, the inventor of this patent, believes that large-scale production of seawater desalination needs to be considered first to realize the large-scale production of seawater desalination. For energy, if we follow the old path of burning a large amount of coal to generate electricity, it will cause environmental pollution and is not conducive to tackling climate change

Embodiment 1

[0015] A seawater desalination device powered by solar power plants on coastal tidal flats. The seawater 1 overflowing the coastal tidal flats is poured into an external seawater storage tank 2 with a water capacity of 4,500 cubic meters. Enter the internal seawater storage tank 22 with a water capacity of 500 cubic meters, the seawater 1 flowing out from the internal seawater storage tank 22 enters the seawater distillation room 23 through the seawater inlet pipe 12, and the electric water pump 13 pressurizes the seawater 1 into the multi-effect still 17 Temporary storage; solar cells 6 with a total production capacity of 550 megawatts are installed on the bridge surface of the viaduct 21 of the viaduct solar power plant, and the power generated by the solar cells 6 is supplied to multiple groups of electric heating devices 20 to heat the multi-effect still 17 to generate salt and water vapor, the water vapor is cooled in the condenser 18 to become fresh water 25.

Embodiment 2

[0017] A seawater desalination device powered by solar power plants on coastal tidal flats. The seawater 1 overflowing the coastal tidal flats is poured into an external seawater storage tank 2 with a water capacity of 8200 cubic meters. The seawater 1 flows through the diversion channel 3 and passes through the wall hole below the enclosure wall 4 Enter the internal seawater storage tank 22 with a water capacity of 700 cubic meters, the seawater 1 flowing out from the internal seawater storage tank 22 enters the seawater distillation room 23 through the seawater inlet pipe 12, and the electric water pump 13 pressurizes the seawater 1 into the multi-effect still 17 Temporary storage; solar cells 6 with a total production capacity of 800 megawatts are installed on the bridge surface of the viaduct 21 of the viaduct solar power plant, and the power generated by the solar cells 6 is supplied to multiple sets of electric heating devices 20 to heat the multi-effect still 17 to genera...

Abstract

The invention relates to a coastal seawater-desalting device powered by a solar power station, belonging to the technical field of new energy application. When a tide comes, an external seawater reservoir is filled with seawater which also fills an internal seawater reservoir by a diversion canal penetrating through an enclosure, then flows into a seawater-distilling room by a seawater inlet pipeand is lifted by an electric water pump in the seawater-distilling room to enter a multi-effect distiller for temporarily storage. Solar batteries mounted on a viaduct surface are shined by sunshine to generate a direct current which is transited into an alternating current by a conductor wire, a controller and an inverter; the alternating current is supplied to an electric heating device in the seawater-distilling room to heat the multi-effect distiller which internally generates steam and salt; the salt is conveyed out from a salt outlet door by a salt conveyor pipe; and the steam enters a fresh-water condensing device in a fresh-water condensing room by a fresh-water-conveying steam pipeline and is cooled before flowing in a fresh-water reservoir through a water outlet pipe.

Description

technical field [0001] The invention relates to a seawater desalination device powered by a coastal beach solar power station, and belongs to the technical field of new energy applications. Background technique [0002] On June 10, 2009, the executive meeting of the State Council passed the "Jiangsu Coastal Area Development Plan" in principle, requiring that by 2020, the three cities of Lianyungang, Yancheng, and Nantong should be transformed from medium-sized cities into super-large cities. To build a super-large city, we first need to solve the problem of fresh water supply. Although Yancheng is close to the Yellow Sea, the annual average salinity of the surface layer of the Yellow Sea is 3.5%. The seawater cannot be directly drunk by humans or animals, nor can it be used to irrigate traditional grain and oil crops. The freshwater resources of the inland rivers in Yancheng, Jiangsu are limited. On February 20, 2009, Hu Wenbiao, the former chairman of Yancheng Biaoxin Che...
