The invention discloses a sulfur loading offgas recycling system and an offgas treatment apparatus thereof. The offgas treatment apparatus is provided in accordance with the specificity of loading overflow offgas which overflows from an opening of a sulfur tanker during sulfur loading. A high-speed rotational liquid ring formed by an alkaline liquid in a pump cavity through a liquid ring pump is mixed with loading overflow offgas sucked via vacuum sucking capacity of the liquid ring pump itself; therefore, sulfur vapor in the loading overflow offgas can be cooled to form solid sulfur by condensing, and in addition, the toxic gas hydrogen sulfide in the loading overflow offgas can gain full contact with the liquid ring and react with the same to produce nontoxic products, the nontoxic products are secondarily purified further through a cleaning tank, so that gas discharged from the cleaning tank meets the environmental protection requirement, and sulfur deposition at the bottom of the cleaning tank is finally discharged through a blow-down pipe fitted to the bottom of the cleaning tank for the purpose of collection. Therefore, harm of sulfur loading offgas to human bodies and the environment can be effectively avoided.
Description
technical field [0001] The invention relates to a sulfur loading tail gas recovery and treatment system and a tail gas treatment device thereof, which are suitable for recovering and treating spilled tail gas during sulfur loading to prevent the tail gas from overflowing into the atmosphere and causing pollution to the atmosphere. Background technique [0002] Sulfur must be in a liquid state when loaded, and the melting point of sulfur is 119°C. Therefore, the loading temperature must be kept above 120°C, and liquid sulfur will produce a large amount of sulfur vapor, hydrogen sulfide and other harmful gases. [0003] At present, the harmful exhaust gas (sulfur steam, hydrogen sulfide, etc.) produced by sulfur loading is generally not treated. During loading, harmful exhaust gas often overflows into the atmosphere through the gap between the feeding pipe and the tank mouth of the sulfur tanker. Hydrogen sulfide and sulfur vapor that will form a large amount of sulfur dust a...
