Oxidation tank with good aerating effect

Abstract

The invention relates to an oxidation tank with a good aerating effect. The oxidation tank comprises a hollow cylinder with an open upper end and a guide cylinder which is vertically arranged in the cylinder and provided with two openings at two ends. A gap is reserved between the hollow cylinder and the guide cylinder, the gap is filled by filler, and an aerating device is further arranged in the guide cylinder. The oxidation tank is characterized by comprising a compressed air pipe and an aerating head communicated with the compressed air pipe; the aerating device further comprises at least two disc-like brackets distributed vertically, wherein a plurality of aerating heads are arranged on each disc-like bracket; and circular grooves corresponding to the disc-like brackets are formed in the wall of the guide cylinder, and the edges of the disc-like brackets are embedded into the circular grooves. According to the oxidation tank provided by the invention, the aerating heads are arranged in the oxidation tank in two layers, so that the aerating effect is enhanced to be beneficial to uniformly mixing materials. The peripheral positions of the aerating heads in two layers can be respectively adjusted, so that the aerating heads are freely combined to form different matched aerating effects by upper and lower layers, and therefore, the optimal aerating effect can be obtained by adjustment in different conditions.

Description

Technical field [0001] The invention relates to a biological oxidation equipment in the chemical and metallurgical fields, in particular to a vertical oxidation tank. Background technique [0002] Oxidation tank is a common equipment in wet smelting, and its cylinder is often equipped with a diversion cylinder to form the circulation of fluid inside the cylinder, so that the materials are uniformly mixed. The deflector is usually equipped with an aeration device to promote the gas-liquid material exchange. However, in the existing oxidation tank, only a single aeration head is installed at a certain height of the deflector. For the oxidation tank, effective and uniform material exchange cannot be formed. Summary of the invention [0003] The invention overcomes the shortcomings of the prior art and provides an oxidation tank with thorough and efficient aeration, adjustable circumferential position of the aeration structure and good aeration effect. [0004] In order to achieve the...

AI Technical Summary

Problems solved by technology

An aeration device is usually installed in the draft tube to promote the material exchange of gas and liquid, but in the existing oxidation tank, only a single aeration head is set at a certain height of the draft tube. For the oxidation tank, it is impossible to form an effective and uniform material exchange
