Problems solved by technology

At present, when testing food-grade carbon dioxide impurities in China, sampling cylinders are often used to take the finished gas and then use offline gas chromatography to manually inject samples for analysis. This detection method inevitably brings uncertainty synthesis and analysis errors. An integrated system and method for on-line monitoring of food-grade CO2 that can guide the production process in time during the process has become an urgent problem to be solved by those skilled in the art

Abstract

The invention discloses an integrated system and method for monitoring food-grade CO2 on line, the integrated system comprises an analysis cabinet, a pretreatment unit, an analyzer combination unit and a tail gas emission unit are installed in the analysis cabinet, and the right side of the analysis cabinet is provided with an anti-explosion air conditioner and a control unit; the upper part of the analysis cabinet is a positive pressure sealing area, and the lower part is a control area; a pressure sensor, a temperature sensor, a bypass throttle valve and an analyzer combination unit are mounted in the positive pressure sealing area; and the control area is provided with an air inlet valve and a pretreatment unit. The analysis system can be used for completing node analysis and finished product gas impurity total analysis in a food-grade carbon dioxide purification process, and the quality of food-grade carbon dioxide product gas is guaranteed. Compared with a traditional analysis method, the integration level is higher, real-time analysis is carried out on a production site, and data can be directly uploaded to a control center.

Description

technical field [0001] The invention relates to an on-line monitoring system and method, in particular to an integrated system and method for on-line monitoring of food-grade CO2, and belongs to the technical field of gas analysis. Background technique [0002] As a food additive, food-grade carbon dioxide is widely used in carbonated beverages, tobacco puffing, food preservation and other fields. The quality of food-grade carbon dioxide will directly affect the health of users. With the improvement of market demand and quality of life, higher requirements are placed on the quality control of product gas. [0003] The source of food-grade carbon dioxide is mostly the recovery of tail gas of chemical products. Due to the large gap between the purification process and production equipment of various production enterprises, the types and contents of impurities caused by different raw gas selected are also different. At present, when testing food-grade carbon dioxide impurities...
