Problems solved by technology

[0004] The above existing technical solutions have the following defects: because the ozone gas will float up in the water, after the ozone passes through the ozone output interface, it will not pass through each air inlet evenly, and will only enter the ozone oxidation through the air inlet located at the upper position. The inner cavity of the reactor, and most of the ozone is accumulated above the inner cavity, and at the same time, the sewage enters vertically downwards and fills the inner cavity, that is, the gas-liquid mixture of ozone and sewage is only located above the inner cavity, so it is necessary to extend the working time of the water stirring mechanism Stirring time can meet the full mixing of ozone and sewage, resulting in low efficiency and poor effect of the overall device

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 , figure 2 Shown, be a kind of ozone catalytic oxidation tower reaction device disclosed by the present invention, comprise tower body 10, tower cover 20 and ozone generator 40, the bottom of tower body 10 inner cavity is provided with liquid inlet pipe 11 and connects with ozone generator The aeration tray 50 of 40, the upper part of the tower body 10 is provided with a liquid outlet pipe 12, and the liquid outlet pipe 12 is connected with the water outlet pipe 13 through the tail gas treatment device 30; the sewage enters the lower part of the inner cavity of the tower body 10 from the liquid inlet pipe 11, The ozone generated by the ozone generator 40 diffuses to the lower part of the inner cavity of the tower body 10 through the aeration tray 50, and is initially mixed with the sewage to form a gas-liquid mixture. The treatment ...

Abstract

The invention relates to a tower type reaction device for ozone catalytic oxidation, which comprises a tower body, a tower cover and an ozone generator. The liquid pipe is provided with a first drainage tube in the tower body; the first drainage tube is sleeved with a second drainage tube with a closed upper part, and an annular mixing chamber is formed between the outer surface of the second drainage tube and the inner wall of the mixing chamber; inside the mixing chamber There are multiple stirring shafts, and multiple stirring blades are set on the stirring shafts. The transmission chamber is equipped with a planetary gear mechanism that drives the stirring shafts to rotate around their own axis and revolve around the axis of the tower body. The gas-liquid mixture formed by ozone and sewage Drain and fill the mixing chamber, and fully stir and mix the gas-liquid mixture, thereby improving the mixing efficiency and mixing effect of ozone and sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to an ozone catalytic oxidation tower reaction device. Background technique [0002] Printing and dyeing wastewater has the characteristics of large water volume and high content of organic pollutants. The dyes contained in the wastewater need to be decolorized. Redox decolorization is a relatively common method in sewage decolorization. Such as the chlorine oxidation method of bleaching water, ozone oxidation method, hydrogen peroxide and electrolysis method, photooxidation method, etc. The use of ozone in sewage treatment is the most extensive. The principle is to use the strong oxidizing property of ozone to interrupt large Molecular chains of molecular organics, turning them into small molecular organics, while reducing COD. [0003] The Chinese patent whose authorized notification number is CN208716924U discloses a sewage decolorization treatment device inclu...
