Oxidation tower for waste salt refining

Abstract

The invention discloses an oxidation tower for waste salt refining. The oxidation tower includes a cylinder and a seal head, an air outlet is arranged on that seal head, a backwash water drain pipe and a water distribution pipe are sequentially arranged on the upper end of the inner part of that cylinder from top to bottom, the right end of the backwash water drain pipe is connected with a backwash water drain pipe adapter pipe which penetrates through the side wall of the cylinder by a backwash water drain pipe flange, the right end of the distribution pipe is connected with a water inlet pipe adapter pipe passing through the side wall of the cylinder by a water inlet pipe flange, a water distribution pipe support is arranged on the inner wall of the cylinder under the water distributionpipe, and an aeration pipe, a water drain pipe and a backwash pipe are arranged at the lower end of the inner part of the cylinder from top to bottom in sequence, and the right end of the aeration pipe is connected with an aeration pipe connecting pipe passing through the side wall of the cylinder through an aeration pipe flange. The invention not only realizes the continuity of feeding and discharging and has high automation degree, but also realizes the nanometer aeration of the reaction solution through the aeration device, improves the treatment efficiency of the waste brine, and has higher practicability.

Description

Technical field [0001] The invention relates to the technical field of industrial waste salt treatment, in particular to an oxidation tower for refining waste salt. Background technique [0002] In the chemical, pesticide, pharmaceutical, dye and other industries, a large amount of waste salt is generated every year, and the treatment methods of industrial waste salt are divided into outsourcing treatment, independent incineration by enterprises, and industrial recycling of waste salt after oxidation treatment. Regardless of economics, environmental protection, etc., recycling waste salt after oxidation treatment is the most ideal treatment method. In the oxidation treatment process of industrial waste salt, it is necessary to use hydrogen peroxide or sodium hypochlorite and other enhanced aqueous solutions for oxidation treatment to remove organic pollutants and other harmful substances in the waste salt. [0003] The utility model with the patent number CN206457254U discloses a ...

[0003] The utility model whose patent number is CN206457254U discloses a kind of hydrogen peroxide oxidation tower, including the oxidation tower upper tower, the oxidation tower middle tower and the oxidation tower lower tower which are arranged sequentially from top to bottom, the oxidation tower upper tower, the oxidation tower middle tower and the oxidation tower lower tower They are respectively composed of cylinders; this utility model connects the mixed liquid treated in the upper tower to the middle tower and the lower tower for reuse, realizes step-by-step utilization, and maximizes the air utilization rate, but the whole oxidation process cannot be realized continuously. type, which requires continuous manual feeding, which increases labor intensity. In addition, although this utility model is utilized step by step to maximize the air utilization rate in the tower, it has no aeration device, and its treatment efficiency in industrial waste water is limited, so it is not applicable Oxidation treatment of industrial waste salt
