Hazardous gas comprehensive detection device

Abstract

The invention relates to an on-the-spot rapid detection device in the safety production field. The hazardous gas comprehensive detection device of the invention comprises a gas sampling module, a detection device and a sampling pipe which is used to perform remote sampling to a limited space with safety potential. Remote gas sampling is performed in the limited space by using the invention and the detection equipment is used to perform rapid and qualitative or quantitative analysis, thus providing accurate analysis data for operation staff and avoiding accident occurrence caused by blind operation in the limited space.

Description

technical field [0001] The invention belongs to an on-site rapid detection device in the field of safe production, in particular to a detection device for rapid quantitative and qualitative detection of gas in a limited space operation site. Background technique [0002] Limited space is a common industrial structure in various industrial production, municipal facilities, transportation storage and other industries. Poor natural ventilation can easily cause accumulation of toxic and harmful, flammable and explosive substances or insufficient oxygen content, which can easily cause acute poisoning and suffocation safety. production accident. From 2006 to 2008, there were 18 accidents of acute poisoning and suffocation in confined spaces in Beijing alone, killing 32 people and injuring 26 people. So far in 2009, there have been 6 acute poisoning and suffocation accidents in limited spaces in Beijing, and 18 people died. [0003] Due to the complex composition of toxic and har...

AI Technical Summary

Problems solved by technology

At present, the detection in the limited space mostly uses the workers to enter the limited space and use the detection equipment to check, and the air composition in the limited space is complex, the commonly used gas detection equipment can only detect a single gas, and dozens of gas detection equipment need to be equipped for detection , thus increasing the stay time of the inspectors who detect gas components in a limited space, which will inevitably pose a potential safety threat to the operators

And equipped with dozens of gas detection equipment with different operation methods and high price, which is difficult for most domestic construction units to afford. As a result, pre-operation detection is not carried out in most limited spaces, resulting in many accidents
