Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Such as figure 1 As shown, the present invention provides a CEMS system intelligent fault detection device, comprising:

[0023] Parameter collection unit 1: collect physical characteristic data and system data of each component in the CEMS system through the operation parameter collection sensor group 11;

[0024] The operating parameter collection sensor group 11 includes:

[0025] Rotameter sensor 111: the sensor has a light emitting end 22 and a light receiving end 23, which are respectively placed on both sides of the monitoring flow meter. When the float 21 is in the specified flow range, it will block the light and affect the light received by the receiving...

Abstract

The invention discloses an intelligent fault detection device of a continuous emission monitoring system (CEMS). The intelligent fault detection device of the CEMS comprises a parameter acquisition unit, a data fault analysis unit, and a fault alarming unit, wherein the parameter collecting unit collects physical characteristic data and system data of each component of the CEMS through running a parameter acquisition sensor group, the data fault analysis unit analyzes a fault component and fault information of the fault component of the CEMS according to the physical characteristic data and system data collected by the parameter collecting unit, the fault alarming unit is connected with external devices or the network and is used for receiving fault information of the fault component generated by the data fault analysis unit and sends out a fault alarming signal. The intelligent fault detection device of the CMES can be widely applied to industries like thermal power plants, waste incineration power plants, chemical plants and paper-making. The intelligent fault detection device of the CMES can greatly improve operational stability of the CEMS, reduce manpower and material resources needed to operate the CEMS, and therefore the running cost and expense of the CEMS are reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas monitoring, in particular to an intelligent fault detection device for a CEMS system. Background technique [0002] CEMS is the abbreviation of Continuous Emission Monitoring System in English. It refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matter emitted by air pollution sources and transmits the information to the competent department in real time. It is called "smoke automatic monitoring system". ", also known as "continuous monitoring system for flue gas emission" or "on-line monitoring system for flue gas". CEMS is composed of gaseous pollutant monitoring subsystem, particulate matter monitoring subsystem, flue gas parameter monitoring subsystem and data acquisition, processing and communication subsystem. The gaseous pollutant monitoring subsystem is mainly used to monitor the gaseous pollutant SO 2 , NO x conce...
