Abstract

The invention discloses a dry-type oxidation reactor for detecting total organic carbon. The dry-type oxidation reactor comprises a sample feeding unit and a burning unit. An air inlet in the sample feeding unit is arranged nearby a burning pipe in the burning unit, an air-tight component is arranged on the periphery of an inlet of the burning pipe and butts against the bottom of a sliding block in the sample feeding unit. Under the effect of a photoelectric sensor, a driving device drives the sliding block to generate two limiting positions, at one limiting position, an injection hole penetrating through the sliding block is arranged at the inlet of the burning pipe and connected with the inlet, and at the other limiting position, other bottoms of the sliding block seal the inlet of the burning pipe. The dry-type oxidation reactor solves the problem of poor air-tightness of a traditional oxidation reactor.

Description

Technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to an oxidation reactor for detecting total organic carbon. Background technique [0002] At present, health and epidemic prevention and water quality monitoring departments are paying more and more attention to the pollution of organic matter in the water. Among them, the detection of total organic carbon (hereinafter referred to as TOC) is indispensable. Various types of TOC monitors have been widely used in these departments. Today TOC monitors use a variety of methods, generally including combustion oxidation method, conductivity method, gas chromatography, etc., while the combustion oxidation method used only requires one-time conversion, with simple flow, good reproducibility, and high sensitivity. TOC The combustion oxidation method used in the determination can oxidize all the organic matter in the water sample. It can be directly used to indicate the total amoun...
