Sulphur recovery unit

The utility model discloses a sulphur recovery unit, steam passes through to get into steam ejector after the steam flow governing valve is adjusted, the steam flow governing valve can make the operation of sulfur production stove more stable, the waste gas that produces in the molten sulfur pond passes through the flue gas leading and gets into steam ejector, steam and waste gas mix the hydrogen sulfide waste gas entering sulfur production stove that the reaction back produced, hydrogen sulfide and air advance the pipe through the air respectively and advance a tub entering sulfur production stove with hydrogen sulfide and carry out sulfur production, sulphur that the sulfur production stove produced and waste gas all get into sulphur recovery unit and retrieve, waste gas in the sulphur recovery unit gets into tail gas incinerator, , tail gas incinerator discharges through the chimney after burning. This process can prevent the secondary pollution that the molten sulfur pond partial waste gas of the degasifi
