Problems solved by technology

Due to the limitation of machining accuracy, the vent hole on the rigid material has a relatively large pore size and a low porosity ratio, and the air bubbles generated during the aeration process are relatively large and the volume is small, so the contact surface between the gas and the liquid is too small , so that the utilization rate of oxygen is very low, and the running kinetic energy consumes a lot
In addition, if the blowing air pressure is lower than the liquid level pressure (or when there is no ventilation), the tube or nozzle shape made of rigid material will pour the liquid back, and it is easy to settle and scale in the inner cavity, and block the aeration hole

Embodiment Construction

[0017] The following specific descriptions of the present invention are given by the examples, which are only used to further illustrate the present invention, and should not be construed as limiting the protection scope of the present invention.

[0018] Such as Figure 1-5 The specific embodiment of the present invention shown includes a tank body 1 and an upper cover 2, the upper cover 2 is provided with an exhaust port 21, and the tank body is provided with a liquid inlet 12 and a liquid outlet 13. During the reaction, the lye enters the tank body from the liquid inlet 12. After the reaction is completed, the liquid in the tank is discharged from the liquid outlet 13. In this embodiment, the liquid outlet 13 is connected with a liquid outlet pipe 131. In addition, in this embodiment The tank body 1 described in the example is fixed with an oblique microporous aeration hose 3, the inner end of the oblique microporous aeration hose 3 is closed, and the outer end is l...

Abstract

The invention discloses an oxidation tank. The oxidation tank comprises a tank body and an upper cover, wherein the upper cover is provided with exhaust ports, the tank body is provided with a liquid inlet and a liquid outlet, an inclined microporous aeration hose is fixedly arranged in the tank body, the inner end of the inclined microporous aeration hose is closed, the outer end is led outside the tank body and is provided with an air inlet, the inclined microporous aeration hose comprises a hose main body made of an elastic flexible material, aeration micropores penetrating the hose wall are uniformly distributed on the hose main body at a high density, and the aeration micropores and the surface of the hose wall are at the non-perpendicular inclined state. The oxygen utilization rate is high, the service life is long, and the oxidation reaction is quick.

Description

technical field [0001] The invention relates to a gas-liquid reaction device, in particular to an oxidation tank. Background technique [0002] In petrochemical, non-ferrous smelting and other production processes, a large amount of reducing toxic liquids such as sulfides or nitrides or heavy metal ions will be produced. At present, these toxic liquids are generally treated by adding lye to the oxidation tank and blowing air. Oxygen in the air oxidizes the toxic liquid, and finally reacts with lye to form stable salts, thereby preventing secondary pollution caused by the toxic liquid. Existing oxidation tanks are generally blown into air through a gas distributor. The more common gas distributor is made of rigid material in the shape of a tube or nozzle, and holes are uniformly distributed on its working surface, and the air is distributed through these dense small holes. Evenly distributed in the liquid, in order to achieve the purpose of aeration to utilize the oxygen in ...
