Continuous factory boundary characteristic pollutant monitoring device

Abstract

The invention discloses a continuous factory boundary characteristic pollutant monitoring device. A remote communication module is connected with a lightning protection device with a sealed inert gaspower discharge tube; a detection module is connected with an electrochemical sensor, a photo-ion gas sensor and a semiconductor sensor; the electrochemical sensor is used for detecting inorganic toxic gases; the photo-ion gas sensor is used for detecting volatile organic compounds; the semiconductor sensor is used for detecting trichloromethane; a zero calibration module is connected with a zerogas generation device; the zero gas generation device is used for reducing concentrations of hydrocarbon and inorganic compounds in the air to be less than a sensor detection limit; a sampling moduleis connected with a main sampler; an insert prevention net and a filter are arranged inside the main sampler; a pretreatment module is connected with a moisture separation component, a purification component and a valve island allocation component; the moisture separation component is provided with a vacuum pump and a drier; the valve island allocation component is connected with a purification tube. By adopting the device, disorder discharge factory boundary concentrations of companies can be monitored in real time, and environment quality situations and change trends can be accurately monitored.

Description

Technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a continuous monitoring device for characteristic pollutants at the plant boundary. Background technique [0002] Characteristic pollutants refer to specific pollutants other than conventional pollutants among the pollutants discharged by the project. Mainly refers to specific pollutants that may cause potential pollution or affect the surrounding environmental air protection goals after the project is implemented. Characteristic pollutants can show the degree of pollution in this industry. Generally speaking, they can be understood in terms of quantity as pollutants that emit more, such as COD, BOD, ethanol, acetone, etc. in the pharmaceutical industry. They refer to the same industry due to production processes and products. The difference can also be different. Another example is that the characteristic pollutants of automobile exhaust are hydrocarbons and NO. X W...
