COD online monitoring system in changeable high-chlorine environment

Abstract

A disclosed COD online monitoring system in a changeable high-chlorine environment comprises a COD monitoring equipment main body, a stabilizing mechanism and an indicating mechanism, one side of the COD monitoring equipment main body is provided with a switch groove, one side of the inner wall of the switch groove is provided with a reagent groove, an inner cavity of the reagent groove is provided with a plurality of reagent bottles at equal intervals, the stabilizing mechanism comprises a fixed block, a plurality of attaching grooves are formed in one side of the fixed block at equal intervals, inverted-J-shaped sliding grooves are symmetrically formed in the two sides of the inner wall of the reagent groove, movable blocks are arranged in inner cavities of the two inverted-J-shaped sliding grooves, rotating holes are symmetrically formed in the opposite faces of the two movable blocks, a rotating shaft is arranged between the two rotating holes, and an extrusion ring is arranged on the outer wall of the rotating shaft. According to the invention, the fixed block, the attaching grooves and the extrusion ring are arranged, the multiple reagent bottles are preliminarily limited through the fixed block and the attaching grooves formed in the fixed block, then the multiple reagent bottles are extruded and positioned in cooperation with the extrusion ring, and the stability of the reagent bottles in the COD online monitoring equipment is improved.

Description

technical field [0001] The invention relates to the technical field of COD on-line monitoring, in particular to an on-line COD monitoring system in a changeable high-chlorine environment. Background technique [0002] COD refers to the amount of oxidant consumed when reducing substances in water are oxidized and decomposed under the action of an external strong oxidant under certain strict conditions, expressed in milligrams of oxygen per liter. COD reflects the degree of water pollution by reducing substances, including organic matter, nitrite, ferrous salts, sulfides, etc., but the amount of inorganic reducing substances in general water and wastewater is relatively small, and is referred to as Organic pollution is very common, so COD can be used as a comprehensive indicator of the relative content of organic substances. [0003] When using COD on-line monitoring equipment in a changeable high-chlorine environment, it is necessary to place multiple reagent bottles in its ...

Problems solved by technology

[0003] When using COD on-line monitoring equipment in a changeable high-chlorine environment, it is necessary to place multiple reagent bottles in its inner cavity. Nowadays, when these reagent bottles are placed, they are randomly placed inside the COD on-line monitoring equipment, which will give people A messy feeling. At the same time, when the COD online monitoring equipment is shaken by external force, the internal reagent bottle will be dumped, which causes waste of resources and reflects the stability of the reagent bottle in the COD online monitoring equipment.
