Water sample pretreatment system for high-turbidity water analysis instrument and working method of water sample pretreatment system

Abstract

The invention discloses a water sample pretreatment system for a high-turbidity water analysis instrument and a working method of the water sample pretreatment system. The water sample pretreatment system comprises a water sample flow control assembly, a primary pretreatment assembly, a bypass pipeline, secondary pretreatment equipment and a water sample analysis instrument, an outlet of the water sample flow control assembly is communicated with an inlet of the primary pretreatment assembly and an inlet of the bypass pipeline; an outlet of the primary pretreatment assembly and an outlet of the bypass pipeline are communicated with an inlet of the secondary pretreatment equipment, and an outlet of the secondary pretreatment equipment is communicated with an inlet of the water sample analysis instrument. The system and the working method thereof can realize continuous monitoring of high-turbidity water by an online chemical instrument.

Description

technical field [0001] The invention belongs to the field of chemical analysis of water quality in industrial production, and relates to a water sample pretreatment system used for high turbidity water analysis instruments and a working method thereof. Background technique [0002] Industrial circulating water, desulfurization slurry of coal-fired power plant desulfurization system, desulfurization wastewater, and coal-containing wastewater are high-turbidity water with high salt content and complex water bodies. For normal operation and to prevent highly turbid water from corroding equipment materials, it is necessary to regularly analyze the water quality of high turbid water in order to control the corrosive ions in the water quality within the acceptable range. [0003] The water quality analysis of highly turbid water is generally manually analyzed by regular sampling. An important reason why online continuous monitoring cannot be realized is that the water body of high...

AI Technical Summary

Problems solved by technology

[0003] The water quality analysis of highly turbid water is generally manually analyzed by regular sampling. An important reason why online continuous monitoring cannot be realized is that the water body of high turbid water is complex, and sludge, suspended solids, and water color may affect the measurement accuracy of online monitoring instruments. Long-term It is also easy to cause fouling of instrument components during operation

If a water sample pretreatment system can be constructed, which can automatically and continuously remove solids such as sludge and suspended matter in high turbidity water, so that the water sample entering the instrument analysis becomes clear and bright, it will be able to better solve the above problems. Realize continuous monitoring of online chemical instruments for highly turbid water, but there is no similar disclosure in the prior art
