A chemical wastewater residual chlorine emission reduction device

Abstract

The invention discloses a chemical wastewater residual chlorine emission reduction device which comprises a residual chlorine emission reducer, wherein a cavity is formed in the residual chlorine emission reducer; a baffle plate is welded to the side wall of the cavity; a mounting hole is formed in the inner wall of one side of the cavity; a bearing plate is moveably mounted inside the mounting hole; a holding groove is formed in the top of the bearing plate; activated carbon is placed in the holding groove; a support plate is welded on one side of the residual chlorine emission reducer; a clamping column groove is formed in the bottom of the bearing plate; a clamping column is mounted inside the clamping column groove in a sliding manner; a clamping groove matched with the clamping columnis formed in the inner wall of the bottom of the mounting hole; the clamping column is clamped with the clamping groove; a sliding hole is formed in the inner wall of one side of the clamping columngroove; a winding wheel is rotationally mounted inside the clamping column groove. The device is good in practicability, simple in structure and convenient to operate, the bearing plate can be conveniently released from fixation, in addition, the activated carbon can be conveniently moved to the outer side of the residual chlorine emission reducer, then a worker can clean or replace the activatedcarbon conveniently, and convenience can be brought to people to use the device.

Description

technical field [0001] The invention relates to the technical field of chemical wastewater treatment equipment, in particular to a chemical wastewater residual chlorine discharge reduction device. Background technique [0002] Residual chlorine, as an effective method of sterilization and disinfection, is still used by more than 80% of the water plants in the world, but this method needs to maintain a certain amount of ClO2 and Cl2 residual chlorine to have a bactericidal effect, and chlorine reacts with organic acids , many carcinogens will be produced, and more than a certain amount of chlorine will cause many harms to the human body, so there is an urgent need for a residual chlorine emission reduction equipment. After retrieval, the patent document with the patent application number of 201520372523.9 discloses a chemical wastewater residual chlorine discharge device, including a residual chlorine discharge reducer, the input end of the residual chlorine discharge reducer...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned design still has shortcomings. The activated carbon needs to be cleaned or replaced after long-term use, but the above-mentioned design is not convenient for removing the activated carbon from the residual chlorine emission reducer, and it is not conducive for workers to clean and replace the activated carbon. Therefore, we propose a A kind of chemical wastewater residual chlorine discharge reduction device is used to solve the above problems
