Intelligent monitoring system for safe and stable operation of high-nitrogen-oxygen-ratio air separation

Abstract

The high-nitrogen-oxygen-ratio air separation safe and stable operation intelligent monitoring system comprises a gas conveying pipeline and an electric appliance box, an audible and visual alarm is fixedly installed at the middle end of the bottom of the outer surface of the electric appliance box, and a controller is fixedly installed at the middle end of the top of an inner cavity of the electric appliance box; an information processor is fixedly installed at the left end of the top of an inner cavity of the electric appliance box, and fixing seats are fixedly connected between the peripheries of the top of the outer surface of the gas conveying pipeline. Under the action of mutual cooperation of the threaded cover, the fixing seat, the top plate, the spring, the annular pressing plate, the annular fixing plate, the nitrogen-oxygen sensor body, the gas conveying pipeline, the information processor, the controller and the audible and visual alarm, the purposes of monitoring nitrogen oxides in waste gas in real time and performing early warning when the nitrogen oxide content is abnormal are achieved; meanwhile, a user can conveniently mount and dismount the nitrogen-oxygen sensor body, and great convenience is brought to later maintenance work of the user.

Description

technical field [0001] The invention relates to the technical field of exhaust gas monitoring, in particular to an intelligent monitoring system for safe and stable operation of a high nitrogen-to-oxygen ratio air separation. Background technique [0002] The exhaust gas produced by burning fuel with air as the source of oxidant usually contains a small but notable amount of various nitrogen oxides (nitrogen monoxide, nitrogen dioxide, etc.), collectively referred to as nitrogen oxides. Among them, nitrogen oxides can not only destroy The ozone layer is converted into acid rain, and it is easy to interact with hydrocarbons or volatile organic compounds in the sun, resulting in photochemical smog, causing respiratory diseases, which seriously threatens the survival and health of human beings. Therefore, nitrogen and oxygen sensors are often used in the exhaust gas emission process. To monitor the nitrogen oxide content in its interior, however, the fixed installation method o...

Problems solved by technology

[0003]The purpose of this invention is to provide an intelligent monitoring system for safe and stable operation of air separation with high nitrogen-oxygen ratio, which has the function of automatic alarm for monitoring abnormalities, and is convenient for users to maintain It solves the problem that the fixed installation method of the existing nitrogen oxide sensor for exhaust gas monitoring is relatively cumbersome, it is not convenient for users to disassemble and maintain later, and at the same time, it is impossible to give timely warning to the staff when the nitrogen oxide content is abnormal
