Abstract

The invention discloses an online sample collection system and method. The invention belongs to the technical field of sample detection. The online sample collection system comprises a first purging system capable of conveying inert gas, a sampling structure, and a second purging system, a first switching structure, a second switching structure and a vacuumizing system which are sequentially connected through pipelines. The first purging system is connected to a pipeline between the first switching structure and the second switching structure, the sampling structure is connected to the secondswitching structure, and the sampling structure is provided with an exhaust port capable of being opened and closed. The first switching structure is connected with a sample injection pipeline, the sample injection pipeline can extend into a solid material of a reaction device, and the second purging system can convey gas of which the type is the same as that of at least one gas in the reaction device. The structure is compact, continuous sampling can be achieved, solid materials are prevented from remaining in the pipelines and the switching structures, and the collection efficiency is high.The freshness of a collected sample and the accuracy of a subsequent sample characterization result can be ensured.

Description

technical field [0001] The invention relates to the technical field of sample detection, in particular to an online sample collection system and method. Background technique [0002] In the process industry, the characterization of the material reaction process is the basis for studying the reaction mechanism, optimizing the reaction parameters, improving the product yield and controlling the reaction process. At present, for the research on the characterization of the process industry's material reaction process, most of them use devices such as thermogravimetric analyzers, fixed bed / fluidized bed reactors, electric heating grid reactors, and Curie point reactors. It can be realized by online or offline detection. Although the above method can be used to analyze the kinetic parameters in the reaction process and to control the reaction process to a certain extent, since the solid particulate matter cannot be obtained during the reaction process, the characterization of the...
