The utility model discloses can effectively solve the biuret gathers and deposit wall built -up phenomenon at urea two -stage process evaporation separator inner wall.
Description
Technical field
This utility model relates to a kind of Flushing nozzle, particularly relates to a kind of flushing for carbamide dual circulation separator
Shower nozzle.
Background technology
Carbamide dual circulation separator is the key equipment in urea production process, and carbamide dual circulation separator is mainly made
With being under high temperature, vacuum condition, after the urine that urine concentration is 99.75% of 94.97%, send into outside Granulation Equipments.
In carbamide dual circulation separator, the accumulation of evaporation byproduct thing biuret and deposition wall cling phenomenon are technical bottleneck always, wall built-up
Can be come off time serious blocking pipeline in a large number, not only has a strong impact on prilling, and greatly reduces conforming product rate.
High temperature urine is imported carbamide dual circulation by straight tube through carbamide dual circulation separator top by prior art divide
In device rinse carbamide dual circulation separator inwall mode, have the disadvantages that 1) rinse scope little；2) urine
In element dual circulation separator, back-mixing occurs, add the urine time of staying, in turn result in biuret production rate and strengthen；3)
Vapour-liquid in carbamide dual circulation separator is insufficient contact causes heat distribution inequality, causes biuret uniformly to melt.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of flushing for carbamide dual circulation separator and sprays
Head, it is possible to effectively solve biuret at the accumulation of carbamide dual circulation separator inwall and deposition wall cling phenomenon.
For realizing above-mentioned technical purpose, this utility model takes techniques below scheme: one is divided for carbamide dual circulation
From the Flushing nozzle of device, this Flushing nozzle includes the feed tube of a upper end open lower end closed, on described feed tube longitudinally
The setting dried layer nozzle sets if interval stretches out；Every layer of described nozzle sets all includes more than three acclivitous nozzles,
Each described nozzle circumference of every layer is disposed in an evenly spaced relation on described feed tube, and each described nozzle all with described enter
The internal connection of liquid pipe.
The nozzle length of the described nozzle sets of each layer increases the most successively, the nozzle of the described nozzle sets of each layer and feed tube
Between angle increase the most successively.
Longitudinally spaced for 15cm between the described nozzle sets of each layer, described nozzle sets is set to three layers, every layer of described nozzle
Group includes four described nozzles, and wherein, the length of each described nozzle of the superiors is 5cm, the superiors each
Angle between described nozzle and feed tube is 30 °；The length of each described nozzle in middle level is 10cm, and middle level is every
Described in one, the angle between nozzle and feed tube is 45 °；The length of undermost each described nozzle is 15cm,
Angle between undermost each described nozzle and feed tube is 60 °.
Described in adjacent two layers, the described nozzle circumferential position between nozzle sets interlocks.
The caliber of described feed tube is 2 ", a length of 45cm.
This utility model is owing to taking above technical scheme, and it has the advantage that 1, this utility model is due at feed liquor
If the longitudinally spaced setting dried layer nozzle sets that stretches out on pipe, therefore, it is possible to uniformly rinse in carbamide dual circulation separator
Biuret on wall, and then effectively solve biuret at the accumulation of carbamide dual circulation separator inwall and deposition wall cling phenomenon.
2, this utility model due to the nozzle length that every layer of nozzle sets is set different, and arrange the nozzle between each layer nozzle sets and
Angle between feed tube is different, therefore, it is possible to further such that high temperature urine uniformly rinses carbamide dual circulation separator
Inwall and top cover inwall, the distribution making the flowing velocity of material and heat energy is more uniform, improves carbamide dual circulation and separates
The mixability of urine mixture in device, improves the distribution time of staying；Increase the turbulence speed of air-flow simultaneously, improve and steam
Send out efficiency, weaken biuret generating rate, reduce energy consumption；Realize effectively rinsing and fusing carbamide dual circulation separation
Device inwall and top cover inwall biuret, it is to avoid the generation of caking carbamide, effectively reduce product disqualification rate, achieve
Good economic benefit.3, this utility model interlocks owing to arranging the nozzle location between adjacent two layers nozzle sets, therefore can
Enough inwalls the most uniformly rinsing carbamide dual circulation separator and top cover inwall.This utility model design simple in construction,
Low cost, easy to operate, can be widely applied to the flushing field of biuret.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the Flushing nozzle for carbamide dual circulation separator of the present utility model includes under upper end open
The feed tube 1 that end seal is closed, if the longitudinally spaced setting dried layer nozzle sets 2 that stretches out on feed tube 1；Every layer of nozzle sets 2
All include that more than three acclivitous nozzles 3, each nozzle 3 circumference of every layer are disposed in an evenly spaced relation in feed tube 1
On, and each nozzle 3 is all internal with feed tube 1 connects；The length of the nozzle 3 of each layer nozzle sets 2 from upper strata under
Layer increases successively；Angle between nozzle 3 and the feed tube 1 of each layer nozzle sets 2 increases to lower floor successively from upper strata.
In a preferred embodiment, in order to rinse further uniformly carbamide dual circulation separator inwall and
Top cover 4 inwall, nozzle 3 circumferential position between adjacent two layers nozzle sets 2 interlocks.
In a preferred embodiment, the caliber of feed tube 1 is 2 " (inch), a length of 45cm.
In a preferred embodiment, longitudinally spaced for 15cm between each layer nozzle sets 2, nozzle sets 2 is set to
