Description
Technical field
The utility model relates to a kind of fertilizer production equipment, specifically in a kind of ammoniation-granulation production of sulfur-based compound fertilizer propylhomoserin and tubular reactor.
Background technology
In traditional fertilizer secondary processing granulation process, need add moisture or steam to granulation material can granulation, but adds moisture or increase is dried load by steam, wastes energy.Ammoniation-granulation S-based compound fertilizer makes full use of the heat energy that sulfuric acid, phosphoric acid or monoammonium phosphate nitration mixture slip and gas ammonia neutralization reaction produce, and the sulfate of ammoniac slip not yet solidified after reaction increases granules feed liquid phase and temperature carries out granulation, do not need in granulation material, to add moisture or steam again, thus reach energy-saving and cost-reducing object.
At present, in propylhomoserin compound fertilizer production technology, generally carry out the neutralization reaction of sulfuric acid and liquefied ammonia with tubular reactor.But the internal diameter uniformity of common tubular reactor, material is streamlined flow wherein, cannot be uniformly mixed, and speed of response is slow, needs the body that design is very long, so that material fully reacts when arrival nozzle.Chinese patent 2009201017057 discloses one " nitre ammonia tubular reactor ", arranges Venturi liner in straight tube, utilizes the variable-diameter structure of Venturi liner to force material to change velocity of flow and direction, improves mixing of materials efficiency, thus fast reaction speed.But simultaneously, because the reaction of the ammonia in propylhomoserin composite heat transfer and sulfuric acid is thermopositive reaction, after shortening reaction process, fast reaction speed, the amount of heat that reaction produces cannot discharge, make the temperature of charge at nozzle place too high, affect the carrying out of subsequent technique, even affect the quality of end product.
Summary of the invention
The utility model is solve the problem to provide that a kind of speed of response is fast, reaction process is short, in the ammoniation-granulation production of sulfur-based compound fertilizer propylhomoserin of temperature-controllable and tubular reactor.
The technical scheme that the utility model adopts for technical solution problem is:
Comprise interior pipe with tubular reactor in ammoniation-granulation production of sulfur-based compound fertilizer propylhomoserin described in the utility model, be arranged on the nozzle of interior pipe one end and be communicated with the acid inlet tube of the pipe the other end, the stage casing of described body is in series with Venturi tube and spiral fin coil, be provided with axis in the inner chamber of described spiral fin coil, between described axis and the inwall of spiral fin coil, be provided with helical fin; The outer tube of the outside suit ring-type of described interior pipe, separated successively by dividing plate in interlayer between described outer tube and interior pipe and be provided with air inlet storehouse, cool storehouse and surge bunker, described air inlet storehouse is communicated with ammonia transfer lime, described air inlet storehouse is communicated with cooling storehouse respectively by the through hole be arranged on dividing plate with surge bunker, and described surge bunker is by setting pore on inner pipe and the inner space of interior pipe.
Owing to have employed said structure, this tubular reactor utilizes Venturi tube and helical fin repeatedly to change speed and the direction of Flow of Goods and Materials, and be conducive to the abundant hybrid reaction of material, speed of response is fast, reaction process is short; Ammonia flows before entering interior tube reaction in cooling storehouse, can give the cooling of interior pipe on the one hand, prevent temperature of reaction too high, can give ammonia preheating on the other hand, prevent the disadvantageous effect that sulfuric acid and the gas ammonia temperature difference are brought greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in the figure, comprise interior pipe 1 with tubular reactor in ammoniation-granulation production of sulfur-based compound fertilizer propylhomoserin described in the utility model, be arranged on the nozzle 3 of interior pipe 1 one end and be communicated with the acid inlet tube 2 of pipe 1 the other end.The stage casing of described body 1 is in series with Venturi tube 5 and spiral fin coil 6, is provided with axis 7 in the inner chamber of described spiral fin coil 6, is provided with helical fin 8 between described axis 7 and the inwall of spiral fin coil 6; The outer tube 9 of the outside suit ring-type of described interior pipe 1, separated successively by dividing plate in interlayer between described outer tube 9 and interior pipe 1 and be provided with air inlet storehouse 10, cool storehouse 12 and surge bunker 4, described air inlet storehouse 10 is communicated with ammonia transfer lime 11, described air inlet storehouse 10 and surge bunker 4 are communicated with cooling storehouse 12 respectively by the through hole be arranged on dividing plate, and described surge bunker 4 is by being arranged on the inner space of pore on interior pipe 1 and interior pipe 1.
In work, inject sulfuric acid from acid inlet tube 2, ammonia transfer lime 11 inputs ammonia.The ammonia used in actual production is mostly volatilized by liquefied ammonia step-down to obtain, and in liquefied ammonia volatilization process, temperature reduces, and needs to absorb amount of heat.The ammonia that temperature is lower enters in the inner chamber of interior pipe 1 by air inlet storehouse 10, cooling storehouse 12 and surge bunker 4 successively, converge with sulfuric acid, by Venturi tube 5 time, passage narrows suddenly, pulp jets enters spiral fin coil 6, and helical fin 8 guides slurry to flow twist, and the good spiral fin coil of heat-conducting effect 6 can absorb the heat of slurry and is delivered on the tube wall of interior pipe 1 simultaneously, the ammonia heat exchange of flowing with tube wall exterior, carries out preheating to ammonia while reducing slurry temperature.Cooling storehouse 12 and ammonia transfer lime 11 are separated by the dividing plate be arranged between air inlet storehouse 10 and cooling storehouse 12, make ammonia can only enter cooling storehouse 12 by the pore be evenly distributed on dividing plate, play the effect being uniformly distributed ammonia, ammonia uniform stream can be made to flow around interior pipe 1, improve heat exchange efficiency.
Finally, reacted slurry sprays from nozzle 3.
