Problems solved by technology

However, limited by the single function of the reaction unit, almost all water quality online monitoring instruments have the problems of poor versatility and scalability. Usually, an instrument can only realize the analysis of a single index or a type of chemical parameter with the same detection principle. This means that in various monitoring applications, it is often necessary to prepare multiple instruments to complete the monitoring of multiple indicators, which brings a series of problems such as poor portability, cumbersome integration and debugging process, and large footprint of the monitoring platform.
In addition, the existing reaction units all adopt the extrusion method of supporting block-sealing ring-reaction vessel to realize the high-temperature and high-pressure sealing of the reaction vessel. To replace the sealing ring, the entire reaction unit needs to be disassembled, which is difficult to maintain

Abstract

The invention provides a multi-functional liquid analysis system and method. The multi-functional liquid analysis system comprises a first pump, a second pump and a third pump. A first switching module is used for enabling an outlet of the first pump to be selectively communicated with an inlet of a first container and an inlet of a second container. The first container and the second container are each provided with an inlet and an outlet. Outlets of the second pump and the third pump are respectively communicated with the inlet of the first container, and the outlet of the first container is communicated with the inlet of the second container. A first valve is arranged on the upstream of the inlet of the second container, and a second valve is arranged on the downstream of the outlet of the second container. A heating module is used for heating liquid in the first container and the second container. The multi-functional liquid analysis system and method have the advantages of multiple functions, good sealing effect and the like.

Description

technical field [0001] The invention relates to water quality detection, in particular to a multifunctional liquid analysis system and method. Background technique [0002] The wet chemical analysis technology of water environment parameters based on flow analysis technology is the main technical route for the research and development of automatic water quality analysis instruments for domestic and foreign commercialization and scientific research applications due to its high degree of automation, simple operation, and good chemical properties. [0003] In online monitoring of water quality, the effective rate of monitoring data is often required to be high (>90%). Therefore, the flow path schemes adopted by the instruments of various manufacturers are: the samples and reagents are pushed down into the tank reaction vessel by the action of the pump valve, After that, the mixed solution completes digestion, color development, titration, distillation and other processes in ...
