Problems solved by technology

The common way to monitor tiny leaks is to take flue gas samples for detection and judgment by gas chromatography or gas chromatography. Traditional samplers cannot withstand high temperatures and the sampling head is too short to penetrate into the flue and collect real samples.

Description

technical field [0001] The invention relates to the technical field of gas sampling and analysis, in particular to a high-temperature gas sampling device. Background technique [0002] The cracking furnace is the main device for the industrial production of basic organic chemical raw materials such as ethylene, propylene, butadiene, and aromatics. Since the pyrolysis reaction requires a high temperature, the furnace tube of the cracking furnace is easily burned out and deformed, and the material medium passing through the furnace tube will leak out, resulting in material waste, environmental pollution and even safety accidents. In order to ensure the safety, environmental protection and efficiency of the production process, and to prevent accidents, it is necessary to monitor whether there is any leakage and find small leakage in time. The common method of monitoring tiny leaks is to take flue gas samples for detection and judgment by gas chromatography or gas chromatograph...
