Description

TECHNICAL FIELD

[0001] The utility model relates to a gas detection technology field, specifically related to a gas detection sampling device. BACKGROUND

[0002] During the maintenance shutdown and production start-up of natural gas purification plants and sulfur-containing oil and gas well stations, there are equipment or pipeline nitrogen replacement operation steps. The replacement purpose in the shutdown stage is to reduce the concentration of combustible gas or hydrogen sulfide to prevent combustion explosion or poisoning accidents during the shutdown stage or maintenance. The replacement purpose in the production start-up stage is to reduce the oxygen content in the system to avoid corrosion. Nitrogen replacement uses detection instruments to detect and sample the replacement situation. Only when the detection data are all qualified can the next operation step be performed. Therefore, the accuracy of the detection sampling data is particularly important during the production start-up and shutdown processes.

[0003] The original sampling method is that the operator carries a gas detection instrument and opens the discharge port of the equipment or pipeline along the process. This gas diffusion sampling method directly detects and samples data opposite the discharge port, which has the following main problems: 1. Distance effect: Because the gas is discharged into the atmosphere, the operator's hand-held portable gas detection instrument has different sampling distances and different values during the detection sampling process. 2. Time effect: Because the detection sampling time is different, the sampling data also changes greatly, and some (part) detection data cannot truly represent the gas composition and content in the equipment and pipeline. 3. Station risk: During the detection sampling process, the gas discharged from the equipment and pipeline directly faces the operator, which has the safety risk of combustion explosion and poisoning of personnel. 4. Cost increase: When detecting and sampling gas discharge, there are many liquid droplets and particulate impurities, which directly flush the portable gas detection instrument, causing the gas detection instrument sensor probe to be frequently damaged, increasing maintenance and repair costs.
