The invention relates to a rapid air dissolution device with micro-bubbles. The rapid air dissolution device with micro-bubbles comprises a horizontal air dissolution tank body, wherein the cross section of the air dissolution tank body is circular, a water inlet tube is connected to one end of the air dissolution tank body, a water outlet tube is connected to the other end of the air dissolution tank body, an air inlet tube is connected to the air dissolution tank body at one end of the water outlet tube, and an air inlet hole is formed in the wall body of the air inlet tube; a plurality of groups of first air dissolution mechanisms which are arranged at intervals are fixed on the inner wall of the air dissolution tank body along the length direction, a group of second air dissolution mechanisms is fixed on the inner wall of the air dissolution tank body between the two adjacent groups of first air dissolution mechanisms, and a plurality of groups of third air dissolution mechanisms which are arranged at intervals are fixed on the inner wall of the air dissolution tank body at the tail part of the first air dissolution mechanism at the aftermost end along the length direction; and in the axis direction of the air dissolution tank body, first air dissolution rods and second air dissolution rods are arranged in a staggered manner, and the second air dissolution rods and third air dissolution rods are arranged in a staggered manner. The rapid air dissolution device with micro-bubbles disclosed by the invention is very energy-saving, and greater in air dissolution efficiency than that of a conventional pressure air dissolution system and system reliability than that of a conventional air dissolution system.
Description
technical field [0001] The invention relates to an air-dissolving device for sewage treatment, in particular to a rapid micro-bubble air-dissolving device. Background technique [0002] The dissolved air system is an indispensable part of the pressure dissolved air flotation system, which provides efficient and stable dissolved air water for the subsequent process of the air flotation system. At present, the volume of the dissolved air system supporting conventional pressure dissolved air flotation in China is relatively large, and the dissolved air efficiency is only 70%~90%, which is generally not high. In addition, the working pressure is 0.35~0.6MPA, which is relatively high. [0003] The commonly used dissolved air system is the vertical packing tank developed by Tongji University 30 years ago. The air-dissolving method of this technology is to fill the ball packing ring in the tank to chop air and water and increase the contact surface area of air and water. This k...
