Liquid concentration detection device

Abstract

The invention discloses a liquid concentration detection device including a first hollow pipe body and a second hollow pipe body; the lower end of the first hollow pipe body is communicated with the upper end of the second hollow pipe body; the interior of the second hollow pipe body is equipped with a prism and a light-emitting assembly from top to bottom; the interior of the first hollow pipe body is equipped with an image sensor; light rays of the light-emitting assembly pass through the prism and project onto the image sensor in the first hollow pipe body; the side wall of the second hollow pipe body is equipped with a plurality of liquid inlets for a liquid to enter the second hollow pipe body and make contact with the prism. The liquid concentration detection device is suitably mounted in pipelines or reaction vessels, is high in detection precision and quick in speed, can be used for real-time detection of small change of the liquid concentration, and is conducive to control of the production process.

Description

technical field [0001] The invention relates to a liquid concentration detection device, in particular to a detection device for detecting liquid concentration through a refractive index. Background technique [0002] The liquid concentration detection device adopts the diffusion law of the spectrum in the liquid, the relationship between the refractive index and the concentration, samples through the high-resolution spectral sensor, analyzes and processes the software to obtain the regularity of the concentration, and then uses temperature compensation to measure Determine the concentration of various liquids or liquid mixtures. In the petrochemical industry, it can be widely used in the detection of petroleum, oil refining and oil blending; in the food industry, it can be used in the production sites of grape juice, tomato juice, fructose syrup, vegetable oil and soft drink processing; dairy industry; paper industry; black pulp, green pulp , white pulp, alkali solution me...

AI Technical Summary

Problems solved by technology

The existing technology generally detects the extracted liquid, and cannot carry out online continuous detection of the liquid in the production process, which is not conducive to the monitoring of the production process, especially for the situation where the concentration of the liquid in the pipeline or container needs to be detected, the existing The liquid concentration detection device cannot be directly installed on the pipeline or container for real-time detection
