Problems solved by technology

It should be emphasized that many VOCs are flammable and explosive. These explosives and leaks will cause great pollution to the environment and cause great losses to human life and property.
If relevant enterprises have hidden dangers in safety management in the storage, production and transportation of these substances, it is very easy to cause major environmental pollution accidents

Abstract

The invention discloses a monitoring system of multi-component gas pollutants in air of a chemical industrial park. The monitoring system comprises a PID sensor, an electrochemical sensor, a catalytic combustion sensor, a geographic information determination apparatus a signal conversion apparatus, a memory, a controller, an acousto-optic alarm apparatus, wherein the PID sensor, the electrochemical sensor, and the catalytic combustion sensor commonly form a part for frontal acquisition and detection of the pollutants of the monitoring system, and the part of the monitoring system is used for pollutant kind determination and parameter coupling analysis. The PID sensor comprises a gas acquisition device, a filtering device, and a photo-ionization sensor detection device; the electrochemical sensor comprises a gas acquisition device, a dedusting device, and an electrochemical sensor detector; and the catalytic combustion sensor detector comprises a gas acquisition device, a catalytic combustion sensor detector, and an outrange and reversed polarity protection device. The monitoring system also comprises the controller for statistics and analysis of detection results, and the acousto-optic alarm apparatus for alarm when the gas concentration in the pollutants exceeds a standard.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a monitoring system for multi-component gas pollutants in the air of a chemical industrial park. Background technique [0002] In recent years, major environmental pollution incidents have occurred frequently in my country, which have seriously affected the ecological environment, people's health and social security. Starting from the actual situation of major environmental pollution incidents in my country, combined with the frontiers of international environmental science and technology development, research and development of a major environmental pollution incident monitoring technology system suitable for my country's national conditions is to improve the level of environmental protection technology in my country and promote the development of an environmentally friendly society. Urgent request. [0003] Among them, "risk source monitoring" mainly focuses on typical pollutants in previ...
