An Ozone Contact Reaction Tank with Gas-Water Rapid Mixing

Abstract

The invention discloses an ozone contact reaction tank for gas-water rapid mixing, which comprises an ozone contact reaction tank, and the contact reaction tank includes an inlet and an outlet; the contact reaction tank is provided with an ozone aeration device, several A first diversion wall extending from the top of the ozone contact reaction tank from top to bottom and a number of second diversion walls extending from the bottom of the ozone contact reaction tank from bottom to top, each first diversion wall is arranged on the adjacent Between the two second diversion walls, a narrow water flow channel is formed between the open bottom of the first diversion wall and the bottom of the ozone contact pool, and the top of the second diversion wall is open to the top of the ozone contact pool A water flow channel is formed between them, the ozone aeration device is arranged below the first diversion wall, there is a gap between the ozone aeration device and the lower surface of the first diversion wall, the ozone contact reaction tank realized by the present invention can avoid ozone Bubbles accumulate around the aeration device for a long time to form a local high concentration, which improves the reaction efficiency.

Description

technical field [0001] The invention relates to the field of fluid treatment by an ozone oxidation method, in particular to an ozone contact reaction tank for rapidly mixing gas and water. Background technique [0002] In recent years, the ozone oxidation method has been widely used in food, pharmaceutical, water supply and other industries due to its advantages in sterilization, disinfection, decolorization, deodorization, oxidation of refractory organic matter and improvement of flocculation effect. Compared with conventional water treatment methods, ozone oxygen flotation oxidation method has better treatment effect on refractory substances, fast degradation speed, small footprint, high degree of automation, no secondary pollution, less scum and sludge generation, At the same time, it has the functions of sterilization, decolorization and anti-scaling. Existing common ozone contact reaction pools (such as figure 1 As shown), it is generally composed of water inlet area ...

AI Technical Summary

Problems solved by technology

Since sewage or tap water generally contain bromide ions, too long a fluid residence time in a local area close to the surface of the aeration device will cause some water bodies to absorb excess ozone and form bromate, which seriously endangers human health. Problems that have been difficult to solve in the ozone oxidation water treatment system

At the same time, due to the long-term accumulation of ozone microbubbles in the lower part of the fluid, the concentration of ozone microbubbles in the upper fluid is not enough to fully react with ozone, which also leads to uneven system response and affects the fluid treatment effect.
