Intelligent benzene series online monitoring system and monitoring method

Abstract

The invention discloses an intelligent benzene series on-line monitoring system and monitoring method, and belongs to the technical field of remote monitoring. The system comprises a sampling module and an analysis module; the sampling module comprises a filter box, and a sealing cover is embedded in the upper end of the filter box; the lower end of the sealing cover is fixedly connected with a filter screen plate, the lower end of the filter screen plate is fixedly connected with a magnetic attraction sheet A, and the inner wall of the lower end of the filter box is fixedly connected with a magnetic attraction sheet B. Sample gas enters the filter box through the sampling pipe, the filter screen plate in the filter box filters the sample gas, dust and large impurities contained in the sample gas are filtered through the filter screen plate, it is avoided that the detection result is affected when benzene series detection is conducted on subsequent sample gas, through the arrangement of a hot cavity, the hot cavity is filled with water; the heating is more uniform through the liquidity of water, so the gas separation efficiency is improved, and the device is suitable for being widely used and popularized.

Description

technical field [0001] The invention relates to the technical field of remote monitoring, in particular to an intelligent on-line monitoring system and method for benzene series. Background technique [0002] The general term for benzene derivatives. In a broad sense, benzene series include all aromatic compounds. In a narrow sense, it refers to compounds containing benzene rings that have a certain distribution in the human production and living environment and are harmful to the human body, including BTEX. Due to production and domestic pollution, benzene series can be widely detected in human living and living environments. And it has strong harm to the blood, nerves and reproductive system of the human body. Developed countries have generally taken the concentration of benzene series in the atmosphere as one of the routine monitoring contents of the atmospheric environment, and stipulated strict indoor and outdoor air quality standards. [0003] At present, there are t...

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following defects in the monitoring technology of benzene series: 1. During the process of collecting sample gas, the sample gas may contain a certain amount of dust impurities, which will affect the subsequent detection results of benzene series in sample gas; 2. , The gas separation chamber 201 is prone to low separation efficiency due to uneven heating during gas separation
