Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection digestion, in particular to a digestion device for water quality detection. Background Technique

[0002] The digestion device for water quality detection is a laboratory device specially used for water quality analysis. Its main function is to convert organic substances in water samples into inorganic substances for subsequent chemical analysis. This device is usually used to measure water quality indicators such as chemical oxygen demand (COD), total phosphorus (TP), and total nitrogen (TN). Common digestion devices for water quality detection include COD microwave digestion instruments and standard COD digestion instruments. The COD microwave digestion instrument uses microwave heating digestion to quickly increase the temperature of the reaction system, shorten the digestion time, and effectively inhibit the oxidation of chloride ions, which is suitable for measuring the chemical oxygen demand of high-chlorine wastewater. The standard COD digestion instrument usually uses ultraviolet or mercury lamp heating to digest the COD sample through chemical reactions and measure the amount of oxidant required.

[0003] At present, during the use of the existing digestion device for water quality detection, since the digestion device needs to heat up and digest the water sample during use, and the space inside the digestion device is small, when taking out the water sample container after digestion, it may scald the staff's arm, which poses a certain danger. To solve this technical problem, the utility model proposes a digestion device for water quality detection. Content of the Utility Model
