Abstract
The utility model discloses a strip tower internals for urea production, internals set up in the top of strip tower air inlet pipeline, communicate with the admission line, internals include guide plate and shower nozzle. The guide plate sets up the guide plate into multilayer horn type. The shower nozzle is lotus flower type shower nozzle. The shower nozzle lies in the middle part of internals, and the guide plate uses the shower nozzle to wind as the center ring. Pass through in the lamellar spacing of gaseous follow guide plate and the aperture of shower nozzle, get into the strip pipe behind the gas uniform distribution. This device can reduce gaseous impact force to internals by a wide margin, extension strip tower internals life and strip tower cycle of operation.
Description
First, technical field
This utility model is related to accessory used in a kind of urea production process, and specifically one kind is used for urea production
Stripping tower internals.
2nd, background technology
At present, with the progress of urea production process technology, carbon dioxide stripping process urea production process has become state
The main technique of interior urea production, stripper as one of visual plant in process for producing urea, according to technique not
With stripper mainly has urea carbon dioxide stripper and two kinds of aminoacid stripping tower, uses carbon dioxide and ammonia respectively as stripping fluid.
Traditional stripping tower internals carbon dioxide or ammonia air inlet top are provided with umbrella baffle plate, and gas impulsive force is big, baffle plate
Easy to fall off, and gas skewness, it is unfavorable for that stripper works.In addition larger gas impulsive force also easily cause internals with
Gas inlet duct junction is damaged and is come off, and leads to stripper cycle of operation to shorten.
3rd, utility model content
This utility model aims to provide a kind of stripping tower internals for urea production, and this device adopts trumpet type to design,
Internals setting trumpet type deflector and lotus-shaped flower shower nozzle, gas is greatly reduced to the impulsive force of internals, extends stripping tower internals
Service life, simultaneously gas be more evenly distributed, using stripper work.
This utility model is used for the stripping tower internals of urea production, and this internals 9 is arranged at the top of stripper air inlet 4 pipeline
Portion, is connected with admission line；Described internals 9 include deflector 10 and shower nozzle 11.
Described deflector 10 is set to multilamellar trumpet type deflector, preferably 2 layers；Described shower nozzle 11 is lotus-shaped flower shower nozzle.
Described shower nozzle 11 is located at the middle part of internals 9, deflector 10 cincture centered on shower nozzle 11.
Gas passes through from the aperture 12 of the lamellar spacing of deflector 10 and shower nozzle 11, and gas enters stripping tube after being uniformly distributed
8.
The beneficial effect that this utility model can reach is：
1st, significantly reduce the impulsive force to internals for the gas, extend stripping tower internals service life and stripper cycle of operation；
2nd, gas is more evenly distributed, using stripper work.
4th, brief description
Fig. 1 is existing stripping tower internals schematic diagram.
Fig. 2 is this utility model stripping tower internals schematic diagram.
Fig. 3 is this utility model stripping tower internals sectional view.
Fig. 4 is this utility model stripping tower internals top view.
In figure, 1 tower body, 2 inlets, 3 liquid outlets, 4 air inlets, 5 gas outlets, 6 steam inlets, 7 condensate outlets, 8 vapour
Carry pipe, 9 internals, 10 deflectors, 11 shower nozzles, 12 apertures.
5th, specific embodiment
With reference to Fig. 2,3,4, non-limiting examples are described below.
This utility model is used for the stripping tower internals 9 of urea production, is arranged at the top of stripper air inlet 4 pipeline, with
Admission line connects；Described internals 9 include deflector 10 and shower nozzle 11.
Described deflector 10 is set to double-deck trumpet type deflector；Described shower nozzle 11 is lotus-shaped flower shower nozzle.
Described shower nozzle 11 is located at the middle part of internals 9, deflector 10 cincture centered on shower nozzle 11.
The gas entering from air inlet 4 passes through from the aperture 12 of the lamellar spacing of deflector 10 and shower nozzle 11, and gas is uniform
Stripping tube 8 is entered after distribution.
