Abstract
The utility model discloses a urea granulating spray head which comprises a conical barrel, a tray, a submergence structure and a flange short joint, wherein the tray is arranged in the conical barrel and positioned on the position of urine which enters the conical barrel; the flange short joint is arranged on the open end side of the conical barrel and covers an opening of the conical barrel; the urea granulating spray head is connected with a granulator through the flange short joint; the submergence structure is a bolted connection structure; the conical barrel is firmly connected with the flange short joint. According to the urea granulating spray head disclosed by the utility model, the granule components with urea granularity ranging from 0.85 mm to 2.8 mm can be increased, the urea dust content is effectively reduced and the washing times of a urea granulating tower is reduced.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, particularly relates to a kind of urea granulation sprayer.
Background technology
In urea production process, tower sprinkling pelleting technology is to use at present comparatively general granulating technique, that is, the concentration molten urea solution that is 99.7% is delivered to the granulation tower top and enter prilling spry, under the turning effort of shower nozzle, the aperture of urea on the shower nozzle wall sprays out the formation drop.Drop meets with upstream air in the decline process, gradually the crystallisation by cooling granulating.
Prilling spry is related to urea product quality particle diameter, if in shower nozzle, have incrustation urine easily form thick dripping and make particles solidify incomplete, in cooling procedure, cause crackle or burst pulverizing because of the moisture evaporation; If shower nozzle aperture smoothness is poor, in granulation process, easily form after the micro-drop of urine solidifies and form dust; If shower nozzle wearing and tearing or asymmetric, can make urine unbalanced, cause sticky tower.Replacing shower nozzle urea need stop granulation and advance the urine groove, and impact consumes.
The utility model content
In view of the above-mentioned deficiency of prior art, the purpose of this utility model is to provide a kind of new urea granulation sprayer, can improve the particle composition of urea size in the 0.85-2.8mm scope, effectively reduces carbamide dust content, reduces the washing time of urea prilling tower.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of urea granulation sprayer, is characterized in that, comprising: conically shaped, and pallet, sink to structure and flange pup joint head; Described pallet is arranged in described conically shaped, is positioned at the position that urine enters described conically shaped; Described flange pup joint head is arranged on the open end side of described conically shaped the opening of this conically shaped of capping, and described urea granulation sprayer is connected with comminutor by this flange pup joint head; And the described structure that sinks to is a bolt fastening structure, and described conically shaped firmly is connected with described flange pup joint head.
Preferably, the described structure that sinks to comprises bolt, packing ring and the nut that cooperatively interacts and tighten, and wherein said nut is positioned at that side further from conically shaped; Described urea granulation sprayer also comprises a location step, and this positioning step is arranged on upper and lower flange assembling position, in order to guarantee the assembling concentricity between described flange pup joint head and described conically shaped; Sidewall at described conically shaped is distributed with a plurality of apertures; The diameter of the described opening of described conically shaped is greater than the diameter of an end relative to this opening.
Urea granulation sprayer of the present utility model can improve the particle composition of urea size in the 0.85-2.8mm scope, effectively reduces carbamide dust content, reduces the washing time of urea prilling tower.
The accompanying drawing explanation
Fig. 1 is the structural representation of urea granulation sprayer of the present utility model.
The specific embodiment
Below, by reference to the accompanying drawings the specific embodiment of urea granulation sprayer of the present utility model is described in detail.
Referring to Fig. 1, urea granulation sprayer of the present utility model is symmetrically a rotary body, comprises conically shaped 1, and pallet 2, sink to structure and flange pup joint head 7.At the sidewall of this conically shaped 1, be distributed with a plurality of apertures; Urine throws away and forms Granular Urea from those apertures.
Described pallet 2 is arranged in conically shaped 1, is positioned at the position that urine enters conically shaped 1.This pallet 2 prevents that the urine that enters urea granulation sprayer from directly impacting the bottom of conically shaped 1, and makes urine be evenly distributed, and is that uniform isopycnic spraying condition is created in the granulation of urea granulation sprayer.
Described flange pup joint head 7 is arranged on the open end side of conically shaped 1 opening of the described conically shaped 1 of capping, and urea granulation sprayer is connected with the comminutor (not shown) by this flange pup joint head 7.
The described structure that sinks to is a bolt fastening structure, for conically shaped 1 firmly is connected with flange pup joint head 7.This sinks to structure and comprises bolt 4, packing ring 5 and the nut 6 that cooperatively interacts and tighten, and wherein said nut is arranged in that side (upside of figure) further from conically shaped 1.For preventing that urea granules that this bolt fastening structure is rebounded from washing away for a long time, cause wear out failure, this bolt fastening structure is designed to a sunk structure.
In order to guarantee the assembling concentricity between flange pup joint head 7 and conically shaped 1, (not shown) arranges a location step 3 at upper and lower flange assembling position.
It is qualified that urea granulation sprayer of the present utility model must be issued to dynamic balance running at the operating condition of 400r/min, requires urea granulation sprayer to be rotary body symmetrically, can meet the requirement of production technology.
The operating process of urea granulation sprayer of the present utility model is as follows.
Urea granulation sprayer is connected with comminutor by flange pup joint head 7.Concentration is 99.7%, the urine of 140 ℃ of temperature enters the urea granulation sprayer of rotation.Urine first touches pallet 2, and urine is evenly distributed; Subsequently, under the centrifugal action that the urea granulation sprayer rotation produces, urine is thrown out of the aperture arranged on urea granulation sprayer, forms wisps of thread.This thread by the short little fluid column of the urea granulation sprayer of High Rotation Speed cutting poling, because liquid has cohesive force, has just formed droplet again, is sprayed on equably on the cross section of whole tower (not shown).In tower, droplet and cooling medium (air) adverse current is met, and at the bottom of after supersolidification and cooling these two processes, falling within tower, forms finished urea.
Above-described is only exemplary preferred embodiment of the present utility model, and purpose is to describe for example the novel embodiment of the utility model, but not be used to limiting scope of the present utility model.Those skilled in the art can, under the instruction of this specification, in the scope that does not deviate from spirit of the present utility model and essence, make the various changes that are equal to.
