Embodiment 1

[0036] see figure 1 , the present invention discloses a seawater desalination and power generation system device based on hydrogen energy, which includes an inlet pump 2, a hydrolysis reactor 3, a hydrogen fuel cell 6, a cooling device 7, a water recovery device 13, a semiconductor refrigeration chip 12, a solar cell Plate 8 and tank 9. The cooling device in this embodiment is a low-temperature cooler, which is used to cool the humid air output from the cathode. Air or seawater is fed into the cryogenic cooler to cool the humid air output from the cathode to normal temperature.

[0037] The inlet pump 2 draws seawater, the seawater outlet port of the inlet pump 2 is connected to the water inlet 19 of the hydrolysis reactor 3, the gas outlet 21 of the hydrolysis reactor 3 is connected to the anode inlet of the hydrogen fuel cell 6, and the cathode of the hydrogen fuel cell 6 is connected to Air, air enters the hydrogen fuel cell from the cathode inlet of the hydrogen fuel cel...

Embodiment 2

[0051] see figure 2 , the cooling device 7 of this embodiment is a counter-current heat exchanger, and the counter-current heat exchanger can be a heat exchanger with light weight and good heat exchange effect such as a plate heat exchanger and a tubular heat exchanger. The interior of the counter-current heat exchanger is provided with two streams of fluids that are isolated from each other and flow relatively, one is cooled humid air, and the other is low-temperature air that cools the humid air. The cooling device 7 is provided with two gas inlets and The gas outlets are respectively the first inlet 26 , the first outlet 27 , the second inlet 28 and the second outlet 29 . The low-temperature air outlet 11 of the second inlet 28 and the water recovery device 13 enters the cooling device 7 from the second inlet 28, and after cooling the cathode humid air, it is discharged through the second outlet 29; the humid air with a higher cathode temperature passes through the cooling...

Abstract

The invention discloses a seawater desalination and refrigeration power generation system device based on hydrogen energy. A water inlet of a hydrolysis reactor is communicated with seawater, an air outlet of the hydrolysis reactor is connected to a hydrogen fuel cell, a wet air outlet of the hydrogen fuel cell is connected to a cooling device, an air outlet end of the cooling device is connected to an air inlet end of a water recovery device, and the water outlet end of the water recovery device is connected to a water tank. According to the device, hydrogen is generated through a hydrolysis reaction of hydride and seawater, the hydrogen reacts with oxygen in the fuel cell to generate fresh water, water and salt in the seawater are separated, a large amount of ions such as Cl<->, Ca<2+> and Mg<2+> in the water can destroy a passive film generated by hydrolysis of the hydride, the generation of a hydrolysis reaction of hydride is promoted, the requirement on a hydrolysis catalyst is reduced, fresh water in wet air is recovered through semiconductor refrigeration and a super-hydrophobic surface technology, and low-temperature air is generated at the same time, so that triple functions of seawater desalination, refrigeration and power generation are realized.

Description

technical field [0001] The invention belongs to the field of seawater desalination and power generation, and in particular relates to a hydrogen energy-based seawater desalination and refrigeration power generation system device. Background technique [0002] Seawater desalination technology turns seawater into freshwater by removing the salt in seawater. In the current situation of increasingly tense fresh water resources, seawater desalination can increase the supply of fresh water in coastal areas, and can also provide necessary fresh water resources for survival on islands, ships and other occasions. [0003] Currently, seawater desalination methods mainly include multi-effect evaporation, multi-stage flash evaporation, pressure steam distillation, reverse osmosis, electrodialysis and freezing. These methods mainly realize the separation of water and salt through physical methods such as evaporation and osmosis, and all existing large-scale seawater desalination plants ...
