Abstract

The invention discloses an apparatus for improving the sulfur recovery ability of a sulfur melting system, and relates to the technical field of recovery of sulfur in the sulfur melting system. The apparatus includes an oxidizing regeneration tank, an intermediate tank, elevated tanks and a sulfur melting kettle which are connected, the overflow opening of the sulfur melting kettle is connected to a semi removal tower through a transfer pump, a cooling pool, a cooling pool pump and a rich liquid tank are orderly connected between the overflow opening of the sulfur melting kettle and the transfer pump, the middle part of the intermediate tank is provided with a liquid outlet, and the outlet of a sulfur foam pump is connected with a liquid transferring tube connected with the rich liquid tube; and a sulfur foam outlet is connected with the sulfur foam pump through a first valve, the outlet of the sulfur foam pump is connected with the elevated tanks through second valves, the liquid outlet of the intermediate tank is connected with the inlet of the sulfur foam pump through a third valve, and the liquid transferring tube is provided with a fourth valve. Compared with apparatuses in the prior art, the apparatus disclosed in the invention allows sulfur foams to be fully settled, separated and concentrated, reduces the load of a sulfur recovery device, and increases the sulfur recovery rate; and a residual liquid generated in the sulfur melting kettle is cooled, settled, separated and recovered to the system, so the resistance of the semi removal is reduced.

Description

technical field [0001] The invention relates to the technical field of sulfur recovery in a sulfur melting system, in particular to equipment for improving the sulfur recovery capacity of the sulfur melting system. Background technique [0002] The feed gas for producing synthetic ammonia contains a certain volume of sulfide. The presence of sulfide will poison the catalyst and increase the corrosion of the equipment. In addition, sulfur itself is also an important resource and should be recovered. Therefore, in In the synthetic ammonia production process, the raw gas is usually desulfurized. [0003] Most domestic synthetic ammonia plants use the wet tannin extraction method to remove sulfides from the raw material gas. The desulfurized liquid from the desulfurization of semi-water gas and the desulfurized liquid from the shift gas are heated and boiled by the sulfur melting system to precipitate elemental sulfur. Sulfur by-product is obtained after cooling. An existing s...
