Abstract
The present invention belongs to the technical field of sulfur recovery processes, and in particular relates to a process for removing and remelting fine powder sulfur from circulating cooling water of a shaping machine of a wet sulfur shaping apparatus. According to the process provided by the present invention, a centrifugal machine and a remelting machine are used as main devices to separate the fine powder sulfur in the circulating cooling water and remelting the fine powder sulfur. By adopting the desulphuration and remelting process provided by the present invention in the production by the wet sulfur shaping apparatus, the content of the fine powder sulfur in the circulating cooling water can be greatly reduced; the water content of the fine powder sulfur entering into the remelting machine is lowered; the remelting efficiency is greatly improved; and the recovery rate of the fine powder sulfur is increased.
Description
Technical field
The invention belongs to recovery technology of sulfur technical field, be specifically related to a kind of technique removing from wet method sulfur forming device forming machine recirculated cooling water, melt fine powder sulphur again.
Background technology
In wet method sulfur forming plant running process, can produce a large amount of fine powder sulphur, fine powder sulphur blocking vibration screen perforation, affects fine powder sulphur removal effect and sulphur water content.Fine powder sulphur enters systemic circulation with recirculated cooling water, and the enrichment of fine powder sulphur, causes the blockings such as tank in shaped device, cooling tower, pump and pipeline, operation is born more and more heavier.Existing fine powder sulphur content is hydrocyclone treatment process from what adopt, this technique can not effectively by fine powder sulphur content from, fine powder sulphur water-content after separation is high, to remelter seriously corroded, in remelter in melting process, thermosteresis is very large, causes fine powder sulphur to melt not in time, on remelter molten sulfur liquid level, fine powder sulphur caking, causes producing.And existing technique employing is conventional molten sulphur, molten sulphur efficiency is low.Need a kind of new technique, the fine powder sulphur in recirculated cooling water can be separated preferably, the fine powder sulphur water-content after separation is low, adopts fast fast thawing sulphur, improves molten sulphur efficiency.
Summary of the invention
The object of the invention is the fine powder sulphur produced to remove wet method sulfur forming device, and realize the treatment process that fine powder sulphur melts utilization and proposition again.
Main technical schemes of the present invention: utilize whizzer to be removed by fine powder sulphur in sulfur forming device, it is characterized by: the fine powder sulphur suspension of solid content 2% is collected into tank, solid-liquid separation is carried out to whizzer by pump delivery, obtain solid phase and the clear liquid of solid content 50%, in molding cycles water, the decreasing ratio of fine powder sulphur can reach 95%.By the conveying of worm conveyor, dewater further, the fine powder sulphur solid content entering remelter can reach 90%.Adopt quick sulfur-melting technology, fine powder sulphur energy Quick uniform is dissolved, is convenient to be transmitted back to system.
Specifically technical scheme of the present invention is: the technique removing, melt fine powder sulphur from wet method sulfur forming device, the technique removing, melt again fine powder sulphur from forming machine recirculated cooling water, it is characterized in that the source by producing fine powder sulphur---the water that vibratory screening apparatus falls collects tank, by pump delivery to whizzer process, the solid solid content after process is made to reach 50%, clear liquid after centrifugal enters clarifying chamber, and solid materials worm conveyor is delivered to remelter and melts.
Usually, for ensureing the processing efficiency of whizzer in this technique, after equipment runs for some time, process water routine cleaning need be passed into.
The molten sulphur of remelter adopts quick sulfur-melting technology, increases the modes such as stirring and improves sulphur melting efficiency, solve the problems such as sulphur caking.
Described whizzer feeding temperature controls at 50 ~ 70 DEG C, and feed pressure controls at 0.1 ~ 0.3MPa.
Described according to whizzer charging solid content, determine the revolution of centrifuge drum.
Described control fine powder sulphur again melting temperatur is 135 ~ 150 DEG C.
Advantage of the present invention:
(1) removing of fine powder sulphur adopts hydrocyclone technique, and one-level hydrocyclone can only about concentrate to 20%, and two-stage hydrocyclone can only about concentrate to 40%, and floor space is comparatively large, and the solid content isolating solid phase does not reach requirement.Adopt whizzer treatment process, only need coagulation, isolating solid phase solid content can reach about 50%, and in recirculated water, the extrusion rate of fine powder sulphur is high.
(2) existing molten ineffective systems again, sulphur lumps and can produce sticky contaminant, and impact is normally produced.Adopt quick sulfur-melting technology, sulphur melting efficiency can be improved, solve the problems such as sulphur caking.
Accompanying drawing explanation
Accompanying drawing 1 is embodiment of the present invention process flow diagram.
In accompanying drawing, 1-tank; 2-whizzer charging pump; 3-whizzer charging pump; 4-whizzer; 5-whizzer; 6-worm conveyor; 7-worm conveyor; 8-worm conveyor; 9-remelter; 10-remelter transferpump.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Case of the present invention is that in this factory's production process, the isolated water yield of vibratory screening apparatus is 92t/h, and solid content is 2% for certain sulfur cream producer 2X90t/h sulfur forming device.When the present embodiment runs, technical process as shown in drawings.To the source of fine powder sulphur be produced---the water that vibratory screening apparatus falls collects tank (1), whizzer (4) process is delivered to pump (2), clear liquid after centrifugal enters clarifying chamber, solid materials worm conveyor (6) is delivered to remelter (9) and melts, and the molten sulfur that melting is good is delivered to fluid cell by remelter transferpump (10).Because the process water yield is comparatively large, the present invention adopts the pattern of two whizzer parallel connections, can conveniently adjust in production process.
For ensureing the processing efficiency of whizzer, after equipment runs for some time, process water routine cleaning need be passed into; The molten sulphur of remelter adopts quick sulfur-melting technology, increases the modes such as stirring and improves sulphur melting efficiency, solve the problems such as sulphur caking.Whizzer feeding temperature controls at about 65 DEG C, and feed pressure controls at about 0.2MPa.According to whizzer charging solid content, determine the revolution of centrifuge drum.Control fine powder sulphur again melting temperatur is about 140 DEG C.
The process of the present embodiment device year water yield 733856t, recyclable fine powder sulphur 11024t, the clear liquid entering system is 722832t.
