A kind of miniature flue gas capture device and method

Abstract

The invention discloses a miniature flue gas trapping device and method, wherein the trapping device specifically includes a trapping bottle equipped with an absorbing liquid, a cooling bottle is set on the outer side of the trapping bottle, and a cooling bottle is set on the top of the trapping bottle respectively. There is an air inlet pipe and an air outlet pipe, and a Cambridge filter is stuck inside the air inlet pipe, the first end of the air inlet pipe is inserted into the trapping bottle and extends to the bottom of the absorption liquid, the second end of the air inlet pipe is connected to the The flue gas outlet is connected, and the first end of the outlet pipe is inserted into the trapping bottle and extends above the absorbing liquid. A miniature flue gas trapping device and method provided by the present invention can simultaneously trap the particulate matter and the gas phase matter of the flue gas, and the gas phase matter can be repeatedly absorbed through reflux to ensure sufficient and complete absorption and improve the efficiency of each group of analysis and testing. The accuracy of the content.

Description

technical field [0001] The invention relates to the technical field of cigarette component analysis, in particular to a miniature smoke collecting device and method. Background technique [0002] More than 4,000 harmful substances produced by burning cigarettes can affect smokers' sleep quality and fertility, leading to chronic bronchitis. Health problems such as osteoporosis can even lead to major diseases such as coronary heart disease and cancer. With the improvement of people's health awareness, more and more attention is paid to the harmful substances in the smoke produced by burning cigarettes, and many products that can reduce the hazards of cigarettes have been designed. The external filter cigarette holder directly intercepts tar and other substances in the smoke through micropores. However, this is only to block harmful substances by means of absorption, and cannot essentially reduce the harm of cigarettes to the human body. [0003] Before the cigarette leaves t...

AI Technical Summary

Problems solved by technology

At present, the analysis of the mainstream smoke components of cigarettes is less, and the capture methods for mainstream smoke are also limited. The developers of smoking machines on the market are mainly from traditional cigarettes such as Sirulin and Bergwatt. These smoking machines are all The smoke capture mode is similar to that of traditional smoking machines, that is, the particulate matter in the mainstream smoke is collected through the Cambridge filter, and the solvent absorbs the gaseous matter in the mainstream smoke. However, the new cigarette is different from the traditional cigarette in that its The proportion of particulate matter in mainstream smoke is greatly reduced, and the proportion of meteorological substances is increased. Therefore, to determine the composition of the whole smoke, both particulate matter and gaseous matter must be captured at the same time, and meteorological substances need to be collected multiple times to reduce experimental errors.
