Description

Technical Field

[0001] This utility model relates to aquaculture water, and more particularly to a hydrogen-rich water production system for aquaculture. Background Technology

[0002] In aquaculture, dissolved oxygen (DO) is a key indicator, but recent studies have found that adding appropriate amounts of hydrogen (H2) to aquaculture water also has significant positive effects. Hydrogen, as a selective antioxidant, can be absorbed by aquatic organisms, helping them resist oxidative stress, enhance immunity, and improve disease resistance, thereby promoting growth and reducing mortality. Furthermore, hydrogen may also participate in regulating the aquatic microbial community and inhibiting harmful bacteria.

[0003] However, when using traditional pump systems similar to aerator pumps for hydrogen delivery, the dissolved hydrogen content in water is low, only 5-7%, which cannot adequately meet the usage requirements. Therefore, existing technologies suffer from the problem of low dissolved hydrogen content in water. Utility Model Content

[0004] The purpose of this invention is to provide a hydrogen-rich water production system for aquaculture. This invention effectively increases the hydrogen solubility in water.

[0005] The technical solution of this utility model is as follows: a hydrogen-rich water production system for aquaculture, including a hydrogen generator connected to a hydrogen mixing assembly, which is connected to a hydrogen water storage tank; the hydrogen mixing assembly includes a negative pressure gas-liquid mixing pump, one end of which is provided with a hydrogen inlet and a water inlet, and the other end is provided with a mixed liquid outlet, the mixed liquid outlet is connected to a Venturi tube, the throat of which is provided with a hydrogen inlet, and the outlet of which is connected to a pressure tank; the pressure tank includes a pressure tank body, a packing layer inside the pressure tank body, a hydrogen aeration port at the bottom of the pressure tank body, a liquid inlet at the top of the pressure tank body, and a liquid outlet at the bottom of the pressure tank body.

[0006] In the aforementioned hydrogen-rich water production system for aquaculture, the packing layer includes multiple layers of inclined packing layers that are distributed vertically and vertically, with adjacent inclined packing layers having opposite inclination directions.

[0007] In the aforementioned hydrogen-rich water production system for aquaculture, the pressure tank is also equipped with a circulation pipe and a circulation pump. The inlet of the circulation pipe is located below the packing layer, and the outlet of the circulation pipe is located above the packing layer. A circulation venturi tube is also connected in series on the circulation pipe.

[0008] In the aforementioned hydrogen-rich water production system for aquaculture, the pressure inside the pressure tank is 0.5-0.6 MPa.

[0009] Compared with existing technologies, this invention optimizes and improves the hydrogen mixing component. It uses a negative pressure gas-liquid mixing pump for initial mixing and dissolution of hydrogen and water, followed by secondary dissolution of the hydrogen through a Venturi tube, effectively increasing the hydrogen solubility in water. Furthermore, this application employs a pressure tank to further enhance the hydrogen solubility. The pressure tank is filled with packing material to increase the gas-liquid contact area, and the hydrogen aeration port is located at the bottom, allowing it to contact the water flow counter-currently during its ascent, further improving dissolution efficiency. In summary, this invention effectively increases the hydrogen solubility in water. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0013] Example. A hydrogen-rich water production system for aquaculture, configured as follows: Figure 1 As shown, the device includes a hydrogen generator 1, which is connected to a hydrogen mixing assembly 2, which is connected to a hydrogen-water storage tank 3. The hydrogen mixing assembly 2 includes a negative pressure gas-liquid mixing pump 21, which has a hydrogen inlet 22 and a water inlet 27 at one end and a mixed liquid outlet 23 at the other end. The mixed liquid outlet 23 is connected to a Venturi tube 24, which has a hydrogen inlet 25 at its throat and a pressurization tank 26 at its outlet. The pressurization tank 26 includes a pressure tank body 261, which has a packing layer 262 inside. The lower part of the pressure tank body 261 has a hydrogen aeration port 263, the top of the pressure tank body 261 has a liquid inlet 264, and the bottom of the pressure tank body 261 has a liquid outlet 265.

[0014] The packing layer 262 comprises multiple layers of inclined packing layers distributed vertically and horizontally, with adjacent inclined packing layers having opposite inclination directions. Rising bubbles collide and shear against the packing surface, continuously breaking down into smaller sizes; the tortuous flow channels significantly extend the residence time of bubbles within the tank. The pressure tank 261 is also provided with a circulation pipe 266 and a circulation pump 267. The inlet of the circulation pipe 266 is located below the packing layer 262, and the outlet of the circulation pipe 266 is located above the packing layer 262. A circulation venturi tube 268 is also connected in series on the circulation pipe 266.

[0015] The pressure inside the pressure tank 261 is 0.5-0.6 MPa.

[0016] The hydrogen inlet, hydrogen port, and hydrogen port of the pressure tank are all connected to the hydrogen generator.

[0017] The pressure tank is also equipped with an exhaust port and a safety valve on the top.

[0018] The hydrogen aeration port is connected to a ceramic microporous aeration disc.

[0019] The specific production process of this utility model of hydrogen-rich water is as follows: Hydrogen is generated by a hydrogen generator and pumped to the hydrogen inlet of a negative pressure gas-liquid mixing pump, the hydrogen inlet at the throat of a venturi tube, and the hydrogen aeration port at the bottom of a pressurized tank. First, the negative pressure gas-liquid mixing pump mixes water and hydrogen and pumps it to the mixed liquid outlet. The water mixed with hydrogen enters the venturi tube and further mixes and dissolves with hydrogen at the throat of the venturi tube, increasing the dissolved hydrogen content. Finally, the mixed liquid enters the pressurized tank from the liquid inlet at the top of the pressurized tank, and hydrogen enters the pressurized tank from the hydrogen aeration port at the bottom. It collides and shears with the packing surface of the packing layer, and the bubbles are continuously broken into smaller sizes, further increasing the dissolved hydrogen content.

[0020] In addition, this application can also use a circulating pump to extract some of the incompletely dissolved gas-water mixture from the tank and send it back into the mixing Venturi jet for secondary or even multiple shear cycles, thereby further increasing the hydrogen solubility in water.

[0021] Finally, the hydrogen-rich water is sent to the hydrogen water storage tank for storage and use through the drain outlet at the top and the corresponding pipes.
