Online ammonia nitrogen monitor

Abstract

The invention relates to the technical field of ammonia nitrogen monitoring equipment, and specifically relates to an ammonia nitrogen online monitor. The monitor comprises a box body, a colorimetricanalyzer, a data processor, a display screen, a sampling tube, a first transparent containing vessel and a second transparent containing vessel, wherein a cavity is formed in the box body, a first spacing transverse plate, a second spacing transverse plate and a third spacing transverse plate are arranged in the cavity from top to bottom, and the box body is divided into a first chamber, a secondchamber, a third chamber and a fourth chamber from top to bottom by the first spacing transverse plate, the second spacing transverse plate and the third spacing transverse plate. The monitor is characterized in that a liquid storage tank and a carbon dioxide storage tank are arranged in the second chamber; and the gas outlet end of the carbon dioxide storage tank is connected with a third flow control valve through a pipeline, the outlet end of the third flow control valve is connected to a horizontal guide pipe, the two ends of the horizontal guide pipe are connected to bottom pipe mountingpipes through bent pipes correspondingly, and inner sliding pipes are slidably connected to the interiors of the bottom pipe mounting pipes.

Description

technical field [0001] The invention relates to the technical field of ammonia nitrogen monitoring equipment, in particular to an ammonia nitrogen online monitor. Background technique [0002] Ammonia nitrogen in water refers to ammonia in the form of free ammonia, which mainly comes from the decomposition products of nitrogen-containing organic matter in domestic sewage under the action of microorganisms, industrial wastewater such as coking ammonia, and farmland drainage. When the content of ammonia nitrogen in the water body is high, it is toxic to fish and also harmful to humans in varying degrees. Determining the content of ammonia nitrogen in water is helpful to evaluate the status of water pollution and "self-purification", so ammonia nitrogen is an important indicator of water quality pollution. [0003] The existing ammonia nitrogen on-line monitor includes a box body, a colorimetric analyzer, a data processor, a display screen, a metering pump, a sampling tube and...

AI Technical Summary

Problems solved by technology

[0004] In the use of the existing ammonia nitrogen online monitor, it is found that the stirring device located in the reaction vessel is not easy to remove from the reaction vessel. In the stirring device and the reaction vessel, the color of the stirring device is collected by the detection probe of the colorimetric analyzer. It will affect the follow-up reaction, but after the color reaction, the position of the stirring device in the colored solution is too close to the color detection point, which will affect the accuracy of color detection. It is difficult to control the amount of salicylic acid added in the later reaction, and it is difficult to accurately detect the color of the color reaction
