Technical Field

[0001] With the growth of my country's economy, a large amount of highly soluble water of various gases is urgently needed in the fields of chemical industry, pharmaceuticals, medical treatment, fertilizers, cosmetics, environmental governance, factory aquaculture, etc. Therefore, there is a huge market demand for improving the production cost and efficiency of highly soluble water of gases, which can also create considerable economic value. Background Art

[0002] The existing gas dissolving equipment mainly includes various types of gas dissolving tanks, air flotation gas dissolving machines, etc. The working principle of the gas dissolving equipment is: using mechanical force to disperse water into fine droplets, increasing the surface area of ​​the water body and fully mixing with the gas; or injecting gas into the water body and forming extremely small bubbles through an ejector, and fully mixing with the water body to achieve the purpose of dissolution. However, no matter which gas dissolving method is used, the following disadvantages exist to varying degrees: such as uneven gas dissolution, high energy consumption, bubble escape, large floor space, high equipment investment, low gas utilization rate, etc.; the existing gas dissolving methods still have a lot of room for improvement, and the utility model has the advantage of solving the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a new type of dissolved gas equipment with simple structure, low energy consumption, high output, low investment, small footprint and high solubility, in view of the problems of uneven dissolved gas, high energy consumption, large floor space, high equipment investment and low gas utilization rate in the above-mentioned existing dissolved gas machines.

[0004] The technical solution of the utility model includes a novel countercurrent type dissolved gas kettle, including a tank body, a recoil ring, a water outlet pipe, an L-shaped water inlet pipe, a partition, an overflow hole, an air pipe interface, a water pump, and an air source. The water pump is connected to the L-shaped water inlet pipe to transport water from the lower part of the tank body into the tank body. The air source transports gas through the air pipe interface. The gas-water mixture enters the L-shaped water inlet pipe and is pressurized by the Venturi principle. The recoil ring is impacted by the shrinking mouth to form a small molecular group of water, which enters the dissolution zone. The gas is highly dissolved under the combined action of high pressure and small molecular groups. The dissolved water carrying the gas enters the discharge zone through the overflow hole and is discharged through the water outlet pipe. discharge; the countercurrent gas dissolving kettle divides the tank body into a dissolving zone and a discharge zone through a partition, which are connected by an overflow hole in the middle; the L-shaped water inlet pipe is connected and fixed through the side wall of the tank body and the partition, and the top water outlet position is a second shrinkage structure; the L-shaped water inlet pipe is a lower water inlet structure, and the water flow of the mixed gas enters the L-shaped water inlet pipe from the bottom, passes through the partition upward and passes through the second shrinkage structure and then enters the dissolving zone; a recoil ring composed of one or more annular devices is installed on the top of the dissolving zone; the upper part of the tank body adopts a shrinkage structure; the lower water inlet structure is adopted, and the L-shaped water inlet pipe passes through the tank body, enters the discharge zone, and passes through the partition to enter the dissolving zone.

[0005] The beneficial effects of the utility model are: simple structure, high gas solubility, low energy consumption, small footprint, high gas utilization rate, low cost, etc. The utility model can be applied to various water-soluble gases such as ammonia, oxygen, chlorine, carbon dioxide, etc. BRIEF DESCRIPTION OF THE DRAWINGS
