On-line fast monitoring instrument for silicate content of industrial water

Abstract

The invention discloses an on-line fast monitoring instrument for silicate content of industrial water, which is provided with a luminescent dish (13) arranged in a darkroom (3). A reagent nozzle (21), a water-sample quantification groove (18), a water-draining electromagnetic valve (20) and a pollution discharge port (23) which are communicated from top to bottom are arranged in the luminescent dish (13); the bottom of the water-sample quantification groove (18) is communicated with a stirring gas path (16); the stirring gas path (16) is connected with a stirring pump (10); the sidewall of the water-sample quantification groove (18) is provided with a water-sample overflow port (17) and a flow-guiding siphon (19); the water-sample overflow port (17) and the flow-guiding siphon (19) are communicated with the pollution discharge port (23) respectively; a water-sample inlet (22) communicated with the water-sample quantification groove (18) is arranged on the luminescent dish (13); the water-sample inlet (22) is provided with a water-sample detector (15); a photoelectric conversion device (14) is also arranged in the darkroom (3); a water-sample-filtering pressure-releasing cup (8) is communicated with the water-sample inlet (22) through a water-sample isolation electromagnetic valve (7) and a water-sample lift pump (6) in turn; and a medicine chest (5) is communicated with the reagent nozzle (21) through a dosing pump (4). The instrument has the advantages of short measurement cycle, no influence from water turbidity and water-sample temperature, as well as precise detection.

Description

Technical field: [0001] The invention relates to an on-line rapid monitor for silicate content in intelligent industrial water by chemiluminescence. Background technique: [0002] The measurement of silicate ion content in generally known water all adopts silicon molybdenum blue colorimetric method (nephelometric method) to finish. Due to the slow chemical reaction of pre-treatment and the measurement period as long as 12 to 15 minutes, the chemical reagent dosing pump used is unstable, the sample quantification is not accurate, and factors such as sample turbidity and temperature affect the measurement results. accuracy. For example, Swiss Swan Company, British ABB Company and domestic products all have such shortcomings. Invention content: [0003] Aiming at the deficiencies of the prior art, the present invention provides an on-line rapid monitor for silicate content in industrial water with a short measurement period, which is not affected by turbidity in water and t...
