Online dust concentration detection system based on capacitor detection technology

Abstract

The invention belongs to the technical field of an online dust concentration detection system based on a capacitor detection technology. According to the technical scheme, an analog-to-digital converter (2) is connected with a control unit (3), a capacitor sensor (5), a voltage\current converter (6) and an amplification unit (7); the control unit (3) is connected with a communication unit (4), the capacitor sensor (5) and the amplification unit (7); the capacitor sensor (5) is connected with the amplification unit (7); detection control software is installed in the control unit (3); a power supply (1) is used for supplying power to the analog-to-digital converter (2), the control unit (3), the communication unit (4), the capacitor sensor (5), the voltage\current converter (6) and the amplification unit (7). The online dust concentration detection system can be used for directly detecting the dust concentration on line, has the characteristics of high detection precision, high detection speed, convenience in use, high anti-jamming capability, safety and reliability, and also has the characteristics of small size, simple structure, short development cycle and suitability for various industrial severe environments.

Description

technical field [0001] The invention belongs to the technical field of on-line detection of dust concentration. Specifically, it relates to an online dust concentration detection system based on capacitance detection technology. Background technique [0002] At present, the control of air pollutants, especially smoke and dust, has attracted much attention. Many countries have formulated many smoke and dust emission standards to limit the emission of industrial smoke and dust. Therefore, it is of great significance for environmental protection management and protection of people's living environment to develop appropriate smoke monitoring methods and grasp the distribution and change rules of smoke and dust. At present, my country has begun to implement the total amount of pollutant discharge control and pollutant discharge fee standard system, which requires the installation of an online monitoring system to grasp the discharge of pollutants. Therefore, the study of online ...
