Gas multipath online monitoring system

Abstract

The invention provides a gas multipath online monitoring system. Multiple sampling branches are arranged, so that gas sampling on multiple positions is realized, omnibearing monitoring can be performed on a field environment, control on on-off of each sampling branch is realized by controlling an electronic control switch on each sampling branch, the electronic control switch of a corresponding branch is turned on when monitoring specific to certain positions needs to be performed, and the electronic control switches of the rest of branches are turned off, so that accurate monitoring on a gasis realized; and a pressure relief branch is arranged, and an electronic control switch on the pressure relief branch is controlled to be turned on when a high pressure environment is detected, so that a certain amount of gas is discharged out, and pressure of the gas entering a gas detector can be effectively adjusted.

Description

technical field [0001] The invention relates to the field of gas monitoring, in particular to a gas multi-channel online monitoring system. Background technique [0002] In the field of industrial production, it is necessary to carry out real-time and effective monitoring of the environment of the chemical industry, so as to be able to find out whether there is any harmful gas leakage in a timely and accurate manner, so as to deal with abnormal production situations in time and minimize environmental pollution and human hazards. [0003] However, in practical applications, the environment of industrial sites is relatively complex, and the types of gases that need to be monitored may be various, and even the location that needs to be monitored is not limited to one place, and most of the gas detectors in the prior art are for certain For the detection of one gas, the detection position is relatively single, and there are also various gas detectors for the same gas. For exampl...

[0003] However, in practical applications, the environment of industrial sites is relatively complex, and the types of gases that need to be monitored may be various, and even the location that needs to be monitored is not limited to one place, and most of the gas detectors in the prior art are for certain For the detection of one gas, the detection position is relatively single, and there are also various gas detectors for the same gas. For example, when detecting vinyl chloride, you can choose laser principle detectors, photon particle detectors (PID) Principle detector, or electrochemical sensor detector

[0004] When it is necessary to monitor multiple gases in multiple locations, more gas detectors need to be installed, which brings great difficulties to the equipment layout on site. Therefore, a monitoring system is required that can be applied to the monitoring of multiple gases and Check multiple locations
