Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen-rich water preparation, and in particular to intelligent hydrogen-rich water equipment. Background Art

[0002] The existing hydrogen-rich water equipment on the market is generally composed of a hydrogen production system, a finished pure water tank, a gas-liquid mixing pump, a hydrogen dissolving tank and a controller. The hydrogen production system generates hydrogen and delivers it to the gas-liquid mixing pump. The gas-liquid mixing pump then extracts water from the finished pure water tank and mixes hydrogen and finished water in the pump. After mixing, the gas-liquid mixture is delivered to the hydrogen dissolving tank for storage. The hydrogen dissolving tank generally has a certain pressure to ensure the formation of a certain concentration of hydrogen-rich water. When hydrogen-rich water is needed, the water outlet of the hydrogen dissolving tank can be opened for extraction.

[0003] It has the following disadvantages: 1. The hydrogen flow rate of the hydrogen production system cannot be adjusted and can only be output at the rated hydrogen production capacity;

[0004] 2. The hydrogen dissolving tank can only be added with finished water with high water quality requirements such as tap water, purified water, mineral water, etc. Therefore, most hydrogen-rich water equipment is generally only suitable for making drinking hydrogen-rich water. In industries with large water consumption such as agriculture and aquaculture, the water cost of making hydrogen-rich water for application will be very high;

[0005] 3. The flow rate and hydrogen concentration of hydrogen-rich water cannot be adjusted. In industries such as agriculture and aquaculture, there is a specified range for the flow rate and hydrogen concentration of hydrogen-rich water. The higher the better.

[0006] 4. The safety factor of the equipment is low. Many hydrogen-rich water equipment do not take measures to monitor and suppress hydrogen leakage and tail hydrogen emissions, which poses a high safety risk.

[0007] 5. Low degree of intelligence. Many hydrogen-rich water devices have rough control logic, incomplete parameter information display, unuser-friendly operation interface, and lack of remote online control and monitoring functions.

[0008] 6. The hydrogen in hydrogen-rich water is easy to separate, the hydrogen concentration is low and the maintenance time is short;

[0009] 7. The hydrogen dissolving tank needs to be under high pressure to dissolve hydrogen into water, which has harsh operating conditions and high safety risks. Utility Model Content
