Sulphur truck loading tail gas collecting system and method

Abstract

The invention discloses a sulphur truck loading tail gas collecting system and method. The sulphur truck loading tail gas collecting system and method are used for processing truck loading overflow tail gas overflowing from a tank port of a sulphur tank truck and preventing damage towards human bodies and environments when a sulphur tank truck loads liquid sulphur in a canning mode. Specifically,when the sulphur tank truck loads the liquid sulphur in a canning mode, the gap between the outer pipe wall of a feeding pipe and the tank port of the sulphur tank truck is sealed; the position for outputting the truck loading overflow tail gas of the feeding pipe is arranged to be of a clamping wall structure, after the truck loading overflow tail gas flows through the clamping wall, the truck loading overflow tail gas flows out from a tail gas output connector on the outer pipe at the clamping wall position, and the truck loading overflow tail gas is prevented from being not capable of beingdischarged and influencing normal working of the sulphur tank truck for loading the liquid sulphur in a canning mode; and then the truck loading overflow tail gas flowing out from the tail gas outputconnector enters a liquid ring pump under the vacuum suction action provided by the liquid ring pump and is mixed with a liquid ring formed by alkaline liquor in the liquid ring pump to perform purification treatment on the truck loading overflow tail gas.

Description

technical field [0001] The invention relates to a tail gas collection system and method for sulfur loading, which is suitable for collecting overflowing tail gas when sulfur is loaded to prevent the tail gas from overflowing into 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 harmful gases such as sulfur tail gas, hydrogen sulfide, and dust. [0003] At present, the harmful exhaust gas (a large amount of sulfur exhaust gas, hydrogen sulfide and dust, etc.) produced by sulfur loading is generally not treated. When loading, harmful exhaust gas often overflows into the atmosphere through the gap between the feeding pipe and the tank mouth of the sulfur tanker, causing great damage to the human body and the environment. Contents of the invention [0004] Aiming at the deficiencies o...
