Description

Technical Field

[0001] The present invention relates to the technical field of seawater hydrogen production, and in particular to a seawater hydrogen production device based on new energy. Background Art

[0002] Hydrogen production from seawater is also known as electrolysis hydrogen production. It is a process of decomposing water into hydrogen and oxygen by electrolysis. Generally, 4.0 to 4.5 kWh of electricity is required to obtain one standard cubic meter of hydrogen. If high-temperature electrolysis of water vapor or other improved methods (such as coating electrodes with various catalysts) are used, it can be reduced to about 3.0 kWh. If solar energy is used as an auxiliary energy source for high-temperature electrolysis, energy consumption can be further reduced. It is an effective method to convert various other energy sources into hydrogen energy storage.

[0003] When producing hydrogen from seawater, in order to reduce the content of impurities in seawater, it is necessary to perform multi-stage filtration on the seawater to avoid a large amount of impurities adhering to the electrodes during the electrolysis of seawater, which may cause corrosion of the electrodes. The impurities generated may also block the filtration structure, resulting in reduced seawater filtration efficiency or insufficient filtration, which may affect the subsequent electrolytic hydrogen production reaction. Traditional filtration of seawater requires multi-stage filtration, and each filter layer filters different materials. The first filter layer of seawater is mainly used to filter visible particles in seawater. After the first filter layer has been used for a long time, the mesh is blocked by impurities, which interferes with the penetration of seawater into the hydrogen production reaction equipment. The filter needs to be cleaned manually. Due to long-term filtration, the adhesion strength of impurities on the filter is high, which is difficult to clean manually. In addition, poor control of the cleaning intensity may cause damage to the filter, affecting the filtration effect of the next filter layer.

[0004] Based on this, a seawater hydrogen production device based on new energy is proposed. Summary of the invention

A water pipe 30 is connected to the outer side of the cleaning nozzle 10, and the water pipe 30 needs to be externally connected to a seawater delivery pipeline. The cleaning nozzle 10 is connected to the connecting frame 2 through a fixing hoop 20; A cleaning brush 9 is arranged below the cleaning nozzle 10, and the lower surface of the cleaning brush 9 is arranged at an angle to improve the cleaning effect while avoiding the filter 5 structure from being blocked.

The hollow holes are provided to avoid interfering with the cleaning nozzle 10 in flushing the filter screen 5, wherein the flushing conditions are divided into two types: First, the filter 5 is cleaned during the hydrogen production process. At this time, there is no need to connect the water pipe 30 structure.

[0027] In summary, the seawater hydrogen production device based on new energy provided in this embodiment, when seawater hydrogen production is required, the device is placed in seawater, and the seawater is pressurized to force the seawater to pass through the filter 5 into the reaction box 4 to complete the electrolysis of seawater to produce hydrogen, wherein the function of the reaction box 4 is to electrolyze the seawater to produce hydrogen. In order to ensure that the electrolysis of seawater is not interfered by impurities, the seawater needs to be filtered before the electrolysis reaction can be carried out; During filtration, the water pipe 30 needs to be connected to the seawater delivery pipeline, and then the motor 11 is manually started, and the motor 11 is used to drive the clamping frame 14 to rotate, and the universal connection end 37 and the connecting piece 33 are used to drive the piston 31 to rise and fall inside the cleaning nozzle 10. When the piston 31 is located at the lower end of the cleaning nozzle 10, one end of the water pipe 30 will be blocked by the piston 31, so that the seawater cannot enter the cleaning nozzle 10. When the piston 31 rises to a height that the structure does not block the passage of the water pipe 30, the seawater enters the cleaning nozzle 10. The lower end of the cleaning nozzle 10 is provided with a mesh. As the piston 31 is pressed downward, the internal seawater forms a water column to impact the filter screen 5 structure; The internal thread block 36 can be slid along the threaded rod 34 in the clamping frame 14 by rotating the hexagonal paddle 35, wherein the axis of the lifting rod 32 is different from the axis of the output shaft of the motor 11, so that when the clamping frame 14 rotates, the piston 31 can be driven to move up and down; When the motor 11 is running, it can drive the bevel gear 12 to rotate, and the bevel gear 12 is used to drive the traction plate 16 to rotate through the belt 27 and the bevel gear 2 13. The non-axial rotation of the traction plate 16 is connected with the traction rod 17, and the traction rod 17 is used to pull the movable folding plate 7 to move back and forth on the horizontal plane. The movable folding plate 7 is elastically connected with a connecting strip 19 structure. When the movable folding plate 7 is close to one side of the reaction box 4, the connecting strip 19 structure will approach and abut against the pushing folding plate 22. When the pushing folding plate 22 abuts against the connecting strip 19, the connecting strip 19 and one side of the movable folding plate 7 are close to each other, and the spring 21 structure is stretched. When the inclined surface of the pushing folding plate 22 contacts the inclined surface of the moving folding plate 7, one end of the pushing folding plate 22 begins to deflect. At this time, the pushing folding plate 22 and the connecting strip 19 abutting point are separated from each other. Before that, the movable folding plate 7 structure will drive the cleaning brush 9 to move slowly on the filter screen 5, so as to achieve the effect of finely cleaning impurities on the filter screen 5 and prevent impurities from adhering to the filter screen 5. When the push folding plate 22 is completely separated from the abutment point with the connecting strip 19, the connecting strip 19 will move quickly under the action of the spring 21, and the cleaning brush 9 will move quickly to achieve the effect of efficient cleaning, that is, the cleaning of the filter 5 is divided into two modes: low-speed fine cleaning and highly efficient cleaning, which greatly improves the cleaning effect and cleaning efficiency of the filter 5. The angle between the inclined part of the push folding plate 22 and the base 1 is smaller than the angle between the inclined part of the moving folding plate 7 and the base 1, so that when the push folding plate 22 contacts the moving folding plate 7, one end of the push folding plate 22 can be deflected and tilted, and the baffle 23 structure is set to prevent the push folding plate 22 from rotating in the opposite direction. By setting the efficient moving cleaning brush 9 in cooperation with the cleaning nozzle 10, impurities are prevented from adhering to the filter 5, the efficiency of seawater entering the reaction box 4 is improved, and interference with the operation of the seawater hydrogen production operation inside the device is avoided.
