Description
Technical field
This utility model is related to Molten sulphur acid-producing apparatus correlative technology field, specifically a kind of Molten sulphur burning
Spray gun.
Background technology
The spray gun process structure of the Molten sulphur antacid used by domestic enterprise is unreasonable at present, is arranged on only with one
The outer corrugated-type expansion joint of sulfur furnace sulfur spray gun interface and common steam chuck composition, production are undesirable always since coming into operation, usually
Because its fault of construction causes spray gun deformation, perforation, the leakage of weld cracking steam to cause to produce unplanned parking.
Sulfur spray gun jacket pipe Main Function is that the temperature for protecting Molten sulphur is less than 159 DEG C, because working as Molten sulphur
When temperature is more than 159 DEG C, its viscosity drastically can be raised, and temperature raises the viscosity that can greatly increase Molten sulphur, causes Molten sulphur
Atomizing effect it is poor, atomizing effect official post obtains the combustion rate of sulfur and substantially reduces, incomplete combustion, while there is substantial amounts of Sublimed Sulfur
Produce, and steam leakage accelerates the corrosion that follow-up equipment is produced to system, increased the maintenance cost and acid production with sulphur of equipment
Production cost, had a strong impact on production.
One expansion joint can not effectively prevent the thermal stress deformation of sulfur spray gun.When incinerator temperature change is big or steam
Technological fluctuation is big or production system because other factorses stop when, expansion joint be insufficient to compensate for incinerator temperature change or
The swell increment that steam cycle fluctuation is produced when big, can usually be such that spray gun deforms toward a direction and tilt, cause weld seam at lance head
Cracking so that jacket steam leaks into production system, corrodes downstream production equipment, and in damage reburner, vanadic anhydride is touched
Matchmaker.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided a kind of service condition is good, use
The Molten sulphur burning spray gun of life-span length.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of Molten sulphur burning spray gun, it is characterised in that including molten sulfur entrance, steam inlet, steam (vapor) outlet, band spiral shell
The chuck of rotation water conservancy diversion reinforcement, expansion joint, lance head, molten sulfur outlet, wherein by molten sulfur entrance, the folder with spiral stream guidance reinforcement
Set and molten sulfur outlet constitute spraygun body, from left to right set gradually in spraygun body steam inlet, steam (vapor) outlet and
Expansion joint, lance head and the jacket pipe with spiral stream guidance reinforcement, and lance head, in the least significant end of spraygun body, molten sulfur outlet sets
Put in the centre position of lance head.Three expansion joints are provided with described steam jacket outer tube.Steam inlet and steam (vapor) outlet
Communicate with the reinforcement chuck of steam spiral stream guidance reinforcement.The reinforcement chuck of carrying vapour spiral stream guidance reinforcement, its spiral stream guidance
The effect of reinforcement, first, strengthen the integral rigidity of sulfur burning spray gun, prevent from being heated excessively and bend.Secondth, steam along
Spiral reinforcing rod flows, and prevents short circuit or dead angle are formed in jacket pipe.Increase spiral shell in dual damascene expansion joint and steam-jacket pipe
Rotation water conservancy diversion reinforcement can effectively prevent the thermal deformation of sulfur spray gun and the soldered cracking between lance head and jacket pipe
Preferably, described steam inlet and steam (vapor) outlet are communicated with the chuck with spiral stream guidance reinforcement.
Preferably, with a circle spiral ribbed stiffener inside the described chuck with spiral stream guidance reinforcement, in order to increase master
The rigidity of body effective heat exchange area and enlarged body tube wall.
Preferably, described expansion joint is outer gibbosity structure, is connected with outermost layer pipeline inside expansion joint.
This utility model has the advantage that：
The service life of spray gun is improve, the maintenance of spray gun is reduced, it is therefore prevented that lance head soldered cracking causes chuck
Interior steam leaks into production system, corrodes downstream production equipment, vanadic anhydride catalyst in damage reburner.
Description of the drawings
Fig. 1 is the structural representation of this utility model Molten sulphur burning spray gun；
Specific embodiment
This utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1, a kind of Molten sulphur burning spray gun, it is characterised in that including molten sulfur entrance 1, steam inlet 2,
The chuck 3 of steam (vapor) outlet 4, band, expansion joint 5, lance head 6, molten sulfur outlet 7, wherein being strengthened by molten sulfur entrance 1, band spiral stream guidance
The chuck 3 of muscle and molten sulfur outlet 7 constitute spraygun body, from left to right set gradually in spraygun body steam inlet 2,
Steam (vapor) outlet 4 and expansion joint 5, are welding between lance head 6 and the chuck with spiral stream guidance reinforcement 3, and lance head 6 are in spray gun
The least significant end of main body, molten sulfur outlet 7 are arranged on the centre of lance head 6, outside the described chuck 3 with spiral stream guidance reinforcement most
Three expansion joints 5 are provided with outer layer pipe, the thermal stress deformation and lance head 6 and outer clip sleeve pipe of sulfur spray gun is effectively prevented
Soldered cracking.
Preferably, described steam inlet 2 and steam (vapor) outlet 4 are communicated with the chuck with spiral stream guidance reinforcement, spray gun work
When making, steam is entered in the chuck 3 with spiral stream guidance reinforcement by steam inlet 2, is discharged by steam (vapor) outlet 4, for protecting liquid
The temperature of body sulfur will not be too high, so as to not affect the ejection of Molten sulphur.
