Abstract
Description
Technical Field
[0001] The utility model relates to the field of tail gas neutralization devices, in particular to a sulfur-containing gas field sampling tail gas neutralization barrel and a sulfur-containing gas field sampling device. Background Art
[0002] During the development of gas wells, it is often necessary to collect and analyze gas samples from the gas wells. The residual gas generated by the gas sampling contains toxic and harmful gases such as hydrogen sulfide, which need to be neutralized by a neutralization barrel filled with alkali solution before being discharged into the atmosphere. During the sampling process, the air flow pressure in the pipeline is relatively high. Although the pressure is reduced by the pressure reducing valve, when the gas enters the neutralization barrel, the sodium hydroxide liquid will still be blown out of the neutralization barrel due to the large pressure difference, causing chemical burns to the skin of personnel and pollution of the station environment. It may also lead to insufficient neutralization of sodium hydroxide and hydrogen sulfide gas in the neutralization barrel, and the discharge of hydrogen sulfide gas will cause personnel poisoning and other hazards.
