Gas dissolving equipment

Abstract

The invention provides gas dissolving equipment, and relates to the technical field of gas-liquid enhanced mass transfer and microbubble generation, the gas dissolving equipment comprises a jet flow nozzle, a tank body assembly and a water outlet pipe which are connected and communicated in sequence, the inner diameter of the jet flow nozzle is reduced from the direction away from the tank body assembly to the direction close to the tank body assembly, and a gas inlet pipe is arranged on the jet flow nozzle; the tank body assembly comprises an outer tank body and a hollow inner cylinder arranged in the outer tank body, the hollow inner cylinder is arranged in the axial direction of the outer tank body, and the water outlet pipe is installed at the tail end of the outer tank body. By means of core components such as the jet flow nozzle, the outer tank body and the hollow inner cylinder, gas dissolving is strengthened in gas-liquid contact strengthening modes such as jet flow breaking, liquid level impacting, jet flow entrainment and inner cylinder circulation, and the gas dissolving equipment has the advantages of being compact in structure, small in occupied area, high in gas dissolving efficiency, not prone to being blocked, low in operation and maintenance cost and the like; the device can be independently used as a dissolved air water preparation device, and can also be used for generating high-quality microbubbles in a connection dissolved air release manner.

Description

Technical field [0001] The present invention involves the technical field of gas -liquid reinforcement and microfoam, especially an air -soluble equipment. Background technique [0002] As a typical type of gas -liquid contact equipment, the gas -soluble equipment is widely used in the actual project, especially as an important front -end equipment for the technology of dissolving gas release micro -foam. The number and quality of the end foam. The better the performance of the dissolved gas equipment, the more gas can be dissolved at the same amount of water. When the qi releases is decompressed by the dissolved gas release, the air bubbles will be generated. The current commonly used gas -soluble water preparation methods include gas -soluble pumps, solubility tanks, gas pipes, etc. Among them, the soluble gas tank has the characteristics of simple structure, stable operation, and strong impact resistance. Therefore Low -efficiency of gas dissolving, large area, and high energy...
