Chemical plant safety early warning method

Abstract

The invention discloses a chemical plant safety early warning method. The harmful gas in the air is detected by using an electrochemical sensor. The concentration of the combustible gas in the environment is detected by using a catalytic bead sensor. The concentration of the toxic gas carbon monoxide in the air is detected by using a solid state sensor. The temperature is detected by using an infrared sensor. The detection results are compared with the threshold and emergency processing is performed when the results exceed the threshold. According to the method, various detection units of the electrochemical sensor, the catalytic bead sensor, the solid state sensor, the infrared sensor and a photoionization sensor are arranged to realize combustible gas concentration detection, toxic gas detection and over-temperature detection, and fast response is performed through a firefighting system, a purging system and a cooling system in case of emergency so that the safety of the chemical plant can be enhanced, and the personal safety of the work personnel can be powerfully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of safety early warning, in particular to a safety early warning method for a chemical plant. Background technique [0002] There are some unsafe or dangerous factors in the process of chemical production, which endanger the health and life safety of employees, and also cause passive production or various accidents. The importance of safe production is to prevent or eliminate harmful effects on workers' health and the occurrence of various accidents, to ensure the safety of people's lives and property, and to ensure normal production and work. [0003] The patent document with the Chinese patent application number 201610480845.4 discloses a chemical production site inspection and meteorological monitoring and early warning system, which monitors various areas of chemical production by setting distributed on-site monitoring units throughout the chemical production site. However, the system cannot detect harm...

[0003] The patent document with the Chinese patent application number 201610480845.4 discloses a chemical production site inspection and meteorological monitoring and early warning system, which monitors various areas of chemical production by setting distributed on-site monitoring units throughout the chemical production site. However, the system cannot detect harmful and flammable gases

[0004] The patent literature with the Chinese patent application number 201610423660.X discloses a fire and explosion prevention early warning and fire extinguishing and explosion prevention method in a chemical plant, which obtains data collected by sensors and performs fuzzy reasoning on the data collected at each fire-prone location. , through fuzzy reasoning to judge the danger level of fire and explosion in each hot and prone location, and issue an early warning when the danger level is output and is a predetermined danger level. However, this method only classifies some conventional dangerous situations and cannot automatically take further measures measure
