Combustion device for water quality detection

Abstract

The invention relates to the field of the water quality detection, more specifically, a combustion device for water detection. The device aims at solving the problem that the measurement error occurssince the activated carbon is likely to adhere a combustion tube wall when being placed in a sample plate. The technical scheme key point is that one combustion device for the water quality detectioncomprises a combustion furnace, a combustion tube penetrating through the combustion furnace, an absorption tube connected to a piercing end of the combustion tube, and a sample plate for placing a sample; the sample plate is stored in the combustion tube, and connected with a push rod; the push rod pierces the combustion tube along a length direction of the combustion tube, and the piercing end of the push rod is connected with a driving mechanism for driving the push rod to move along the length direction of the combustion tube; and a support plate for supporting the sample plate is arrangedat a port of the combustion tube. Through the design of the driving mechanism, the sample plate can automatically extend out from the combustion tube, thereby conveniently, accurately and directly filling the activated carbon in the sample plate.

Description

technical field [0001] The invention relates to the field of water quality detection, more specifically, it relates to a combustion device for water quality detection. Background technique [0002] AOX refers to Absorbable Organic Halogen (Absorbable Organic Halogen), because of its teratogenic, carcinogenic and mutagenic properties, the determination of AOX organic halogens (organic chlorine, organic fluorine, organic bromine) has become an important water quality control in the environmental testing industry index. [0003] The determination of adsorbable organic halides in water includes microcoulometry (GB / T15959-1995) and ion chromatography (HJ / T83-2001). Both methods need to use a core component - a high temperature Combustion furnace (temperature set at 950°C). [0004] However, when the activated carbon particles adsorbing organic halides are put into a high-temperature combustion furnace for calcination, since the activated carbon particles have just been taken ou...

[0004] However, when the activated carbon particles adsorbing organic halides are put into a high-temperature combustion furnace for calcination, since the activated carbon particles have just been taken out of the water to be tested and are very wet, they may stick to the combustion tube when they are put in, resulting in measurement results error occurred
