Description
Technical field
The present invention relates to a kind of sulphur foam that adopts wet desulphurization to produce to sulfurous gas for chemical fertilizer factory, coke-oven plant and carry out sulphurThe device reclaiming, relates in particular to a kind of filtering type sulfur melting kettle.
Background technology
The common collection storage of sulphur foam that chemical fertilizer factory, coke-oven plant produce sulfurous gas employing wet desulphurization is at sulphur foam tankIn, sulfur melting kettle be exactly for process these sulphur foams equipment. In sulphur foam, sulphur adheres to the molecule of elemental sulfurIn foam. Sulfur melting kettle when operation, utilize compressed air or lye pump by sulphur foam delivery in sulfur melting kettle, sulfur melting kettle isJacketed vessel, in chuck, logical steam heats sulphur foam, in the time being heated to 70-90 DEG C, lather collapse, moleculeElemental sulfur assemble rapidly increase, separate with doctor solution. The top of sulfur melting kettle is provided with one and is easy to doctor solution and enters, collectAnd doctor solution (clear liquid) collector that stops sulfur granules to enter. Doctor solution after collection is got rid of outside sulfur melting kettle and is recycled to desulfurization systemSystem recycles. Remaining sulfur granules sinks down into the bottom of sulfur melting kettle by deadweight, molten sulphur heater is installed in the bottom of sulfur melting kettle,The particle sinking constantly accumulates, and constantly heats simultaneously, in the time being heated to 120-130 DEG C, becomes be easy to flow moltenMelt the sulphur of state, get rid of outside sulfur melting kettle, after cooling, become blocks of solid sulphur and reclaim.
Find in actual use, while adopting traditional sulfur melting kettle that clear liquid is separated with elemental sulfur, have some problems, as 1) stillWall accumulated slag cleaning difficulty. Because of very easily accumulated slag of sulfur melting kettle wall, not only reduce the dischargeable capacity of sulfur melting kettle, directly affect heatTransmission speed, and it is extremely difficult to remove the sulphur slag being attached on still wall, and utilization rate of equipment and installations is difficult to improve; 2) production processUnstable, molten sulphur efficiency is not high; 3) clear liquid is of poor quality, and sulphur grade is low, because being entrained with not molten sulphur slag in clear liquid, easilyCause the obstruction of pipeline and tower equipment; Because of sulfur product outward appearance blackout, sulfur content is low, affects market sale in addition; 4)Energy consumption is large, and production cost is high.
Summary of the invention
The invention provides a kind of filtering type sulfur melting kettle, the mode that adopts rotary sieve to add scraper plate is filtered sulphur foam, energyEnough sulfur contents greatly reducing in clear liquid, improve sulfur product quality and the rate of recovery, reduce energy consumption.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of filtering type sulfur melting kettle, comprises the clear liquid section, fillter section and the molten sulphur section that are successively set in kettle from top to bottom, itsMiddle fillter section is provided with rotary sieve, drives by the drive unit that is arranged on still top; Clear liquid section is established purified liquor outlet, and fillter section is establishedSulphur foam entrance, establishes sulphur outlet at the bottom of molten sulphur section.
Described rotary sieve is cage modle filter screen, under drive unit drives, can rotate around axis, and drive unit is buncher.
Described clear liquid section, fillter section and molten sulphur section are placed in respectively independent kettle, between each section of kettle, connect by flange, itsMiddle clear liquid section is directly communicated with fillter section, between fillter section and molten sulphur section, is communicated with by the cone section of shrinking downwards, cone section outsideTwo sections of junctions along the circumferential direction evenly arrange several communicating pipes.
Described communicating pipe, upper end was higher than cone section upper surface 20～50mm.
On kettle outside described rotary sieve, establish fixing scraper plate.
Described molten sulphur section is provided with steam jacket outward.
Compared with prior art, the invention has the beneficial effects as follows:
1) rotary sieve can separate the clear liquid in sulphur foam with elemental sulfur, and the sulphur being attached on filter screen is passed through to scraper plateScrape into molten sulphur section, sulfur product quality is good, and the rate of recovery is high;
2) fillter section is provided with scraper plate, and molten sulphur section is established cone section, and still wall is difficult for accumulated slag, and the design of syllogic kettle, is easy to cleaning,Convenient for maintaining is changed, and utilization rate of equipment and installations is high;
3) in clear liquid, sulfur content is little, is difficult for blocking pipe, directly retrieval system utilization;
4) equipment can be handling strong, stable production process, and energy consumption is little, and can reduce production costs.
