Embodiment

[0030] combined with Figure 4The slurry tank is divided into large and small chambers. The two large chambers are independent, corresponding to the two upstream vacuum belt conveyors. The sulfur slurry in the large chamber overflows to the small chamber. After optimization, the two small chambers are connected to each other. The sulfur slurry in the small chamber passes through The sulfur foam is pumped to the sulfur melting kettle. A total of four sulfur foam pumps, two sulfur foam pumps of A series correspond to two sulfur melting kettles, and two sulfur foam pumps of B series correspond to the other two sulfur melting kettles. After optimization, the rated flow rate of the sulfur foam pump is increased from 2.16m3 / h to 10m3 / h, the head is increased from 50m to 60m, and the pressure of the sulfur melting tank can be maintained at 0.5-0.6MPa. The sulfur melting kettle is heated by low-pressure steam to change the sulfur into liquid and separate with water in the kettle. Th...

Abstract

The invention discloses a sulphur refining equipment system, comprising a sulphur slurrying basin, a plurality of sulphur foam pumps, sulphur melting kettles, a liquid sulphur tank, a liquid sulphur pump, a granulator and a packaging machine. The sulphur slurrying basin is divided into two big chambers and two small chambers and the small chambers are communicated through a connecting pipe; the sulphur foam pumps are arranged at the bottom of the sulphur slurrying basin; the sulphur melting kettles are arranged at the bottom of the sulphur slurrying basin and are communicated with the sulphurfoam pumps; clear liquid discharge pipelines are respectively arranged at the bottom of the sulphur melting kettles; the liquid sulphur tank is arranged beside the sulphur melting kettles and communicated with the sulphur melting kettles; the liquid sulphur pump is arranged on one side of the liquid sulphur tanks. The sulphur refining equipment system is stable and efficient in running and provides a guarantee to full refining of sulphur; sulphur products prepared by the system have high good quality and high purity. Compared with the other processes for producing sulphur cream or blocks only,the system is much environmentally friendly and has remarkable benefit.

Description

technical field [0001] The invention relates to the technical field of sulfur refining equipment, in particular to a sulfur refining equipment system, especially a sulfur refining equipment system based on a sulfur recovery unit of the integrated coal gasification combined cycle power generation technology. Background technique [0002] In the usual coal gasification sulfur refining process, only the sulfur melting system is generally included. The sulfur slurry uniformly mixed with the paste sulfur and demineralized water is transported to the sulfur melting tank through the sulfur foam pump, and the sulfur becomes liquid after being heated by low-pressure steam. The kettle is separated with water. The supernatant liquid is discharged to the wastewater treatment system, and the liquid sulfur in the lower layer is discharged regularly, or discharged to a storage tank to be produced in the form of liquid sulfur, or discharged to an iron box to be produced in the form of sulfu...
