High-efficiency detection device and detection method for benzene-based volatile organic components

Abstract

The high-efficiency detection device and detection method of benzene-based volatile organic components belong to the technical field of benzene-based volatile detection. In order to solve the problem of using a set of sampling equipment for multiple sampling, it is necessary to replace multiple sets of activated carbon sampling tubes intermittently. For The clamping of the activated carbon sampling tube and the need to disassemble and collect sections A and B after sampling is not convenient enough, and the connection between the activated carbon sampling tube and the exhaust mechanism is relatively inconvenient; the invention uses the umbrella on the top of the double-head motor The bevel gear meshes with the second meshing disc, and then under the action of the clamping assembly, the two sets of clamping blocks clamp the sampling tube, and the first telescopic cylinder is stretched out, so that the bevel gear at the bottom of the double-head motor meshes with the first meshing disc, under the clamping of the clamping assembly and the rotation of the limit shaft and the movable rod, the glass tubes of the two groups are separated. Groups of activated carbon adsorption blocks were disassembled and collected.

Description

technical field [0001] The invention relates to the technical field of benzene-based volatility detection, in particular to an efficient detection device and detection method for benzene-based volatile organic components. Background technique [0002] Benzene series is a general term for derivatives of benzene. In a broad sense, benzene series includes all aromatic compounds. In a narrow sense, it refers to benzene-containing compounds that have a certain distribution in the production and living environment of human beings and cause harm to the human body, including BTEX. Cyclic compounds and benzene series can be widely detected in human living and living environment, and have strong harm to human blood, nerve and reproductive system. [0003] At present, the common detection method for benzene-based volatile substances is gas chromatography, which is firstly adsorbed by activated carbon, then decomposed by carbon disulfide, and finally detected by gas chromatography. The...

Problems solved by technology

[0005] The purpose of the present invention is to provide an efficient detection device and detection method for benzene-based volatile organic components, which solves the problem that the content of benzene-based volatiles is different due to the different decoration layout and furniture of each room when detecting indoors in the background technology. , the entire house is sealed and then sampled, resulting in a large deviation in the accuracy of the data. When sampling each room individually, multiple sets of sampling equipment are required. When using one set of sampling equipment for multiple sampling, It is necessary to replace multiple groups of activated carbon sampling tubes intermittently, and the operation is cumbersome. It is not convenient to clamp the activated carbon sampling tube after the replacement of the activated carbon sampling tube and to disassemble and collect the A and B segments after the sampling is completed. In addition, due to the need Replace the activated carbon sampling tube, the connection between the activated carbon sampling tube and the exhaust mechanism is relatively inconvenient
