Integrated sampling calibration constant-pressure alkalization measurement device

Abstract

The invention provides an integrated sampling calibration constant-pressure alkalization measurement device. The device comprises a measuring cell, wherein a measuring assembly is arranged in the measuring cell, an outlet of the measuring cell is communicated with a sewage discharge cell through a pipeline, an inlet of the measuring cell is communicated with an alkalization solution pipe, the alkalization solution pipe is sequentially communicated with a water sample injection pipe and a calibration liquid bottle, and a constant-pressure sample injection assembly is arranged between the watersample injection pipe and the alkalization solution pipe; a sample injection valve is arranged on the water sample injection pipe, and a calibration liquid valve is arranged at an outlet of the calibration liquid bottle; the alkalization solution pipe between the constant-pressure sample injection assembly and the measuring cell is communicated and connected with a pressure-stabilizing alkalization gas assembly, and the length of the alkalization solution pipe between the pressure-stabilizing alkalization gas assembly and the measuring pool is 60-80cm. According to the invention, the problemsof integrated alkalization and integrated structure layout of sample water and calibration solution are solved, so that the flow path is simpler, the alkalization effect is more obvious, the flow fault and maintenance cost are greatly reduced, the reliability of the instrument is greatly improved, and the service life of the instrument is greatly prolonged.
