Problems solved by technology
[0003] The traditional malodorous gas monitoring is mainly local manual monitoring on a regular basis. The monitoring results are not uploaded to the monitoring center or monitoring station in real time, and the problems cannot be found in time, and the monitoring results cannot be fed back in real time. The concentration of gas exceeds the emission standard, which will affect human health and even life

The invention discloses a malodorous gas online monitoring device. The device is mainly formed by a gas channel reversing unit, a first filtering unit, a second filtering unit, an air pump unit, a third filtering unit, a sensor module, a control unit and a data transmission unit. According to the main effect of the device, the control unit realizes regular zero calibration of the sensor module through a reversing valve unit, the first filtering unit, the second filtering unit and the third filtering unit filter moisture and impurities in malodorous gas to guarantee the accuracy and the stability of online monitoring of sensors, the control unit acquires the concentration of the malodorous gas monitored by the sensor module, and the concentration of the malodorous gas is uploaded to a monitoring center or a monitoring station through the data transmission unit to realize the function of online monitoring of the malodorous gas. According to the device, zero calibration of the sensors isregularly and automatically performed, the moisture and the impurities in the malodorous gas are filtered in three levels, the concentration of the malodorous gas is monitored in an online manner, monitoring data is uploaded in real time, the accuracy and the stability of online monitoring of the sensors can be effectively guaranteed, the continuous operation time of the system is increased, and the false alarm rate is reduced.
Description
technical field [0001] The invention relates to the field of environmental protection, in particular to an on-line monitoring device for malodorous gas, which can regularly and automatically perform sensor zero point calibration, filter moisture and impurities in malodorous gas in three stages, monitor the concentration of malodorous gas online, and upload monitoring data in real time, which can effectively Ensure the accuracy and stability of online sensor monitoring, improve the continuous running time of the system, and reduce the false alarm rate. Background technique [0002] Malodorous gas not only has a serious impact on the ecological environment, but also has great harm to human health. It will cause disorders and lesions in the central nervous system, and cause chronic diseases, acute diseases and other diseases. In order to reduce the impact of malodorous gas on human health and even life, it is necessary to take effective measures to control the hazards of malodo...
