Description

Technical Field

[0001] The present application relates to the technical field of dissolved gas tanks, and in particular to a constant pressure dissolved gas device. Background Art

[0002] The pressure dissolved air tank is a special air dissolving device for flotation water purification process. It is a closed type of pressurized container. It realizes full contact and mass transfer between water and air in the tank, so that air is dissolved in water to reach the saturation level as much as possible. There are many types of pressure dissolved air tanks. It is generally recommended to use a spray-type filling tank supplied by an air compressor.

[0003] The Chinese patent with application number CN202223589199.5 discloses a pressure gas dissolving tank, including a gas dissolving tank body, a drain pipe is installed at the bottom end of the gas dissolving tank body, an air inlet pipe is installed on one side of the top of the gas dissolving tank body, a water inlet pipe is installed on the other side of the top of the gas dissolving tank body, and one end of the water inlet pipe extends to the inside of the gas dissolving tank body and is installed with a connecting pipe, and a U-shaped pipe is installed at the bottom end of the connecting pipe. The utility model is provided with two groups of circular water pipes and multiple groups of water outlet nozzles, so that the pressure water can be sprayed more evenly into the gas dissolving tank body, and then the servo motor is driven to drive the connecting shaft to rotate forward and reversely, and cooperate with the rotating sleeve block and the connecting frame to make the U-shaped pipe and the circular water pipe swing forward and backward, so as to further adjust the spraying direction of the pressure water, so that the pressure water can be sprayed more evenly into the packing layer, so that the pressure water and the compressed air can contact more fully in the packing layer, and the mass transfer efficiency is higher.

[0004] When implementing the above technical solution, there is a disadvantage in the process of mixing water and air in the tank: the connection between the drive motor and the stirring rod needs to be punched on the side wall of the tank so that the drive motor can drive the stirring rod to stir. However, this practice may cause rust and leakage at the punched holes later, thereby shortening the service life of the equipment. Utility Model Content
