Abstract
The utility model discloses a sulfur smelting kettle which is high in sulfur treatment capacity, can reduce the production amount of secondary salt and alleviate the environment pollution and is capable of smelting sulfur mud. The sulfur smelting kettle comprises a kettle body, a material inlet pipe, a material outlet and a conical material distributor, wherein a heating sleeve is arranged on the middle lower part of the kettle body; a steam inlet and a liquid outlet are formed in the heating sleeve; the heating sleeve is divided into an upper heating sleeve and a lower heating sleeve; a connection pipe is arranged in the kettle body on the lower heating sleeve; two ends of the connection pipe are communicated with the lower heating sleeve; the connection pipe is positioned on the upper surface of a conical bottom; an opening of the material inlet pipe faces the conical part of the conical material distributor in the kettle body; a clearance is reserved between the conical material distributor and the kettle body. The upper temperature of the sulfur smelting kettle can be controlled to be below 50 DEG C, so that the secondary salt production amount can be effectively reduced, the corrosion to equipment is effectively alleviated, and the service life of the sulfur smelting kettle is prolonged. Produced clean liquid is not directly discharged and is recycled, so that the pollution to the environment is reduced.
Description
Technical field
The utility model relates to the equipment that extracts elemental sulfur, particularly a kind of sulfur melting kettle of fusible sulphur mud.
Background technology
Hydrogen sulfide destroys serious to atmosphere; because of the needs of environmental protection; present each chemical fertilizer factory and coke-oven plant have all built wet desulfurization system; hydrogen sulfide in coal gas is removed in desulfurizing tower; remove liquid after hydrogen sulfide and deliver to regenerator and contact in air, under the catalytic action of sulfonation peptide nitrile cobalt desulphurization catalyst, generate and after elemental sulfur is suspended in regenerator top, flow to foam tank and process.The most of continuous sulfur melting method that adopts of current each factory, foam sulphur in foam tank is beaten to sulfur melting kettle by foam pump, in sulfur melting kettle, be provided with conic distributor, the feed pipe mouth of pipe is the cone point to conic distributor just, foam sulphur is drained into and in the gap forming between kettle and conic distributor, enters into the heating of sulfur melting kettle middle part again by conic distributor after the feed pipe mouth of pipe, the still wall of kettle middle and lower part is provided with a heating jacket, in heating jacket, be connected with water vapour, when the foam sulphur at sulfur melting kettle middle part is heated to 130 DEG C by water vapour in heating jacket, sulfur melting kettle upper temp is 90 DEG C, the temperature of purified liquor outlet is also 90 DEG C.Foam sulphur makes bubble breakup after heating, the elemental sulfur forming after division sinks to gathering sulfur melting kettle bottom and flows out sulfur melting kettle through discharging opening, and the clear liquid of formation flows in desulphurization system and processes again after rising to sulfur melting kettle top after the leakage fluid dram on sulfur melting kettle top flows out.Because of leakage fluid dram mouth excess Temperature, having a large amount of secondary salts produces, production practices prove, when doctor solution temperature exceedes 50 DEG C, secondary salt content can be doubled and redoubled, outlet temperature is 90 DEG C now, thereby owing to entering the intrasystem secondary salt content too fast drawbacks such as the bad and apprehensive regeneration of regenerator sulphur foam of etching apparatus, desulfuration efficiency is bad that caused that rise, and now for guarantee desulphurization plant is normally worked, extend its service life, just, directly discharging from leakage fluid dram clear liquid out, it is no longer entered in desulphurization system.Because clear liquid directly discharges environment has been caused to certain pollution.Now a lot of chemical fertilizer factories and coke-oven plant change sulfur melting kettle into filter press or centrifuge, take a favorable turn and give up rear system desulphurizing ability, due to the sulphur slag of filter press or centrifuge output, nobody want, only has heap to put away, but the bad processing of sulphur cream filtering out, also further contaminated environment.
Summary of the invention
It is large that the utility model is to provide a kind of processing sulphur ability, reduces secondary salt generation, reduces the sulfur melting kettle of the fusible sulphur mud of environmental pollution.
Technical solutions of the utility model complete like this, a kind of sulfur melting kettle of fusible sulphur mud, include kettle, feed pipe, discharging opening, conic distributor, kettle middle and lower part is provided with heating jacket, heating jacket is provided with air intake, liquid outlet, it is characterized in that: described heating jacket is divided into heating jacket and lower heating jacket.
Further preferred version, the sulfur melting kettle inside at lower heating jacket place is provided with tube connector, tube connector two ends are communicated with lower heating jacket, tube connector be positioned at conical lower portion above.
Further preferred version, the described feed pipe mouth of pipe is relative with the tapering of conic distributor that is located at sulfur melting kettle inside, between conic distributor and kettle, is provided with gap.
Technique effect of the present utility model is, because sulfur melting kettle upper temp can be controlled in below 50 DEG C, can effectively reduce secondary salt growing amount, effectively alleviates the degree of corrosion to equipment, the service life of extension device.Due to not directly discharge of the clear liquid producing, but recycle, reduced the pollution to environment.
