Benzene volatile organic component efficient detection device and detection method

Abstract

The invention discloses an efficient detection device and method for benzene volatile organic components, belongs to the technical field of benzene volatile detection, and aims to solve the problems that when one set of sampling equipment is used for sampling for multiple times, a plurality of groups of activated carbon sampling pipes need to be replaced discontinuously; the problems that clamping of the activated carbon sampling pipe and disassembly and collection of a section A and a section B after sampling are not convenient enough, and connection between the activated carbon sampling pipe and an air exhaust mechanism is inconvenient are solved. An umbrella-shaped gear at the top of a double-head motor is meshed with a second meshing disc, then under the action of a clamping assembly, two sets of clamping blocks clamp a sampling pipe, a first telescopic air cylinder stretches out, so that the umbrella-shaped gear at the bottom of the double-head motor is meshed with a first meshing disc, and under clamping of the clamping assembly and rotation of a limiting shaft and a movable rod, the sampling pipe is clamped by the umbrella-shaped gear at the bottom of the double-head motor. According to the invention, the clamping of the sampling tube after the sampling tube is replaced and the disassembly and collection of the two groups of activated carbon adsorption blocks after the sampling is completed are realized.

Description

technical field [0001] The invention relates to the technical field of benzene series volatile detection, in particular to an efficient detection device and a detection method for benzene series volatile organic components. Background technique [0002] Benzene series is the 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 human production and living environment and cause harm to the human body, including BTEX. Cyclic compounds and benzene series can be widely detected in human living and living environments, and are highly harmful to the blood, nerves, and reproductive systems of the human body. [0003] At present, the common detection method of benzene-based volatile substances is gas chromatography, which first uses activated carbon adsorption, then carbon disulfide analysis, and finally uses gas chromatography for...

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
