Abstract
The utility model discloses an absorbing device used for urea production. The absorbing device comprises an absorption cylinder. The upper portion of the absorption cylinder is smaller than the lower portion of the absorption cylinder in terms of internal diameter. Tower plates are arranged in a cavity on the upper portion of the absorption cylinder. A gas distributor is disposed in a cavity on the lower portion of the absorption cylinder. The lower portion of the absorption cylinder is equipped with a plurality of liquid distribution plates that are capable of removing foam. The liquid distribution plates are arranged to be parallel to each up and down and to be separated from each other to allow rising air flow to form a bending channel. The advantages of the absorbing device are that the device is capable of effectively preventing liquid foam from floating upwardly from the lower portion of the absorption cylinder to cause an excessive gas-to-liquid ratio, so that absorptivity of carbon dioxide and ammonia gas is increased, the carbon dioxide and the ammonia gas can be fully contacted and reacted to generate methylamine, the production cost of urea is effectively lowered, and the production efficiency and production capacity of urea are improved.

Technical field
The utility model relates to the technical field of urea production, especially relates to an a kind of suction device for urea production.
Background technology
Existing a kind of application number is that the CN200720080462.4 name is called the Chinese utility model patent of " one section ammonia absorber of urea plant ", one section ammonia absorber of urea plant is disclosed, fine wash sections and bubbling segment with upper and lower layout, described fine wash sections is provided with some column plates, and described bubbling segment is provided with the dielectric distribution device; Described bubbling segment also is provided with the medium quadratic distribution device that is made of some blocks of porous plates, and this medium quadratic distribution device is positioned at above the dielectric distribution device; From bottom to top successively decrease in the aperture of the MEDIA FLOW through hole on each porous plate, the quantity of the MEDIA FLOW through hole on each porous plate from bottom to top increases progressively.It is applicable to one section ammonia absorber inner piece reform in increasing on total recycle urea plants production, make that one section absorption tower bubbling segment bubbling of urea unreacted reactant is evenly distributed, absorbs more fully, fine wash sections load reduction, backflow ammonia consumption reduce, steady production operation, effect of energy are obvious.But the column plate flux on this absorption tower is little, and gas liquid ratio is excessive, thereby makes carbon dioxide absorption incomplete, so production efficiency is not high, so the structure on this absorption tower needs further improvement.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can effectively carbon dioxide and ammonia be reclaimed a suction device that is used for urea production that generates the first ammonium salt solution by ammoniacal liquor for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this is used for one of urea production and inhales device, include absorbing barrel, the internal diameter on described absorbing barrel top is less than the internal diameter of bottom, be provided with column plate in the inner chamber on absorbing barrel top, and be provided with gas distributor in the inner chamber of absorbing barrel bottom, it is characterized in that: the bottom of described absorbing barrel be provided with some can be except the liquid distributing board that defoams, described liquid distributing board is parallel and mutually stagger and the structure that makes ascending air form bending channel is set together with the up and down.
As improvement, the concrete number that can remove the liquid distributing board that defoams of described some be three.
Improve, described gas distributor comprises air inlet pipe and breather pipe again, and described breather pipe is connected with source of the gas by air inlet pipe.
Improve, described breather pipe be pair annulars again, and between two annulus, the straight tube by mutual cross arrangement is connected.
Improve again, be distributed with pore along hoop on described breather pipe.
Improve again, the perforate direction of described pore be oblique under, and the angle of inclination is 30 °～60 °.
Improve, the top of described absorbing barrel and the junction of bottom are pyramidal structure again.
Improve again, be provided with the valve of energy opening and closing air inlet pipe on described air inlet pipe.
Improve, the bottom of described absorbing barrel is connected with cooler again.
compared with prior art, the bottom that the utility model has the advantage of absorbing barrel is provided with some can be except the liquid distributing board that defoams, described liquid distributing board is parallel and mutually stagger and make ascending air form bending channel to be set together with the up and down, this structure can prevent effectively that liquid foam from floating up and causing gas liquid ratio excessive from the bottom of absorbing barrel, thereby improved the absorptivity of carbon dioxide and ammonia, make the abundant haptoreaction of carbon dioxide and ammonia and generate the first ammonium, therefore this device reclaims unreacted carbon dioxide and ammonia effectively, thereby effectively reduced the production cost of urea, and production efficiency and the production capacity of urea have been improved.In addition, this device production cost is low, and small investment is highly suitable for urea production.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this is used for one of urea production and inhales device, include absorbing barrel 1, the internal diameter on described absorbing barrel 1 top is less than the internal diameter of bottom, be provided with column plate 2 in the inner chamber on absorbing barrel 1 top, and be provided with gas distributor 3 in the inner chamber of absorbing barrel 1 bottom, and the bottom of described absorbing barrel 1 is provided with three can be except the liquid distributing board 4 that defoams, and described liquid distributing board 4 is parallel and mutually stagger and the structure that makes ascending air form bending channel is set together with the up and down.The gas distributor 3 of this device comprises air inlet pipe 31 and breather pipe 32, be provided with the valve 35 of energy opening and closing air inlet pipe 31 on air inlet pipe 31, described breather pipe 32 is connected with source of the gas by air inlet pipe 31, breather pipe 32 is two annulars, and the straight tube 33 that is the starlight shape by mutual intersection between two annulus is connected.Be distributed with pore 34 along hoop on breather pipe 32, and the perforate direction of pore 34 be oblique under, and angle of inclination a is 30 °～60 °.The top of absorbing barrel 1 and the junction of bottom are pyramidal structure.The bottom of absorbing barrel 1 is connected with cooler.
Operation principle is as follows:
with ammoniacal liquor from column plate 2 ejection downwards at absorbing barrel 1 top and through falling on liquid distributing board 4 after absorbing barrel 1 inner chamber, simultaneously, open the valve 35 on air inlet pipe 31, allow unabsorbed gases (carbon dioxide and ammonia) enter breather pipe 32 by air inlet pipe 31, and enter in the cavity of absorbing barrel 1 bottom by the pore 34 on breather pipe 32, with through liquid distributing board 4 is tortuous flow after with the ascending air that flows in absorbing barrel 1 lower lumen in carbon dioxide and ammonia gas react generate the first ammonium salt solution, the first ammonium salt solution that generates flows into next process from absorbing barrel 1 outlet at bottom 10.The complete gas (carbon dioxide and ammonia) of unreacted continues to rise through liquid distributing board 4 and in entering absorbing barrel 1 top inner chamber in absorbing barrel 1 lower lumen, contact with the ammoniacal liquor that sprays from column plate 2 and continue to react, further generate the first ammonium salt solution, thereby carbon dioxide and ammonia are absorbed to most, because liquid distributing board 4 is for be arranged on the bottom of absorbing barrel 1 interlacedly, stop the floating of liquid foam, make carbon dioxide can fully contact with ammoniacal liquor and absorb more complete with ammonia.
