Description
Technical field
The utility model relates to the field of gas-liquid separator in urea production, is specifically related to a kind of vapor seperator for urea production.
Background technology
In urea production process, general employing evaporization process is removed the moisture in the aqueous solution of urea after synthesis by vacuum evaporation, more urea droplet is generally carried secretly in indirect steam, urea easily accumulates at the front end place of the top of vapor seperator and escape pipe, and be reacted into biuret further at this, biuret is cumulative, the vacuum of evaporating reactor is made not reach production requirement, in further finished product, moisture raises, affect the normal work of vapo(u)rization system, system loading is caused to run, need stop to vaporising device, dwelling is invited to manage, make the labour intensity of operating personnel large, and the bad control of product quality.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of vapor seperator for urea production, has high insulating effect, advantage that disintegrate-quality is high.
For reaching above object, the technical scheme that the utility model is taked is:
A kind of vapor seperator for urea production, comprise for separating of cylindrical shell, with the rotary separator being arranged at described cylindrical shell side, the upper end of described cylindrical shell is provided with gas outlet, the gas outlet of described cylindrical shell is connected with inverted U-shaped escape pipe, and described cylindrical shell internal upper part is provided with flusher, and described flusher is positioned at below described gas outlet, for rinsing the madial wall of described cylindrical shell near gas outlet place, described escape pipe is provided with flushing-liquid pipe near the side of gas outlet.
On the basis of technique scheme, described flusher comprises flushing liquor main pipeline and shower nozzle, and ringwise, described flushing liquor main pipeline stretches into described inner barrel and connects described shower nozzle described shower nozzle, described nozzle uniform intervals is installed on described shower nozzle, and described nozzle is towards described cylindrical shell madial wall.
On the basis of technique scheme, described flushing-liquid pipe comprises flushing liquor vertical tube and flushing liquor transverse tube, the water side of described flushing liquor vertical tube is positioned at described escape pipe and towards gas outlet, the water side of described flushing liquor transverse tube is positioned at described escape pipe segmental arc, and described flushing liquor vertical tube is connected described flushing liquor main pipeline respectively with described flushing liquor transverse tube.
On the basis of technique scheme, described flushing liquor main pipeline, flushing liquor vertical tube and flushing liquor transverse tube are equipped with valve.
On the basis of technique scheme, described cylindrical shell outer surface of upper is embedded insulating tube, and described insulating tube distributes in the shape of a spiral.
Compared with prior art, the utility model has the advantage of:
(1) in the utility model, escape pipe is arranged to inverted U, if formation biuret, biuret is accumulated in escape pipe front end as much as possible, and the flushing-liquid pipe be arranged on escape pipe is cleaned escape pipe front end and gas outlet inwall, realize perfect flushing, the vacuum of maintenance equipment, the impact that product quality is subject to is little, high-grade-goods rate obviously rises, heat is boiled number of times and is also reduced a lot, and the urea content of ammonia vessel also obviously declines, alleviate the burden of hydrolysis system, fundamentally solve existing equipment Problems existing, prevent from forming biuret, there is design ingenious, the simple advantage of structure.
(2) flusher in the utility model comprises annular nozzle and is arranged on the nozzle on annular nozzle, annular nozzle is positioned at inner barrel, can to the comprehensive cleaning of inner barrel annular, the liquid that nozzle ejects has certain scouring force, urea droplet on inwall can be washed away totally, avoid urea droplet to form biuret, the nozzle in different apertures can also be exchanged as required.
(3) valve in the utility model, according to need of production, can carry out alternately opening, controls flush position, washing time and washing time flexibly.
(4) insulating tube in the utility model is embedded on barrel outer surface, avoid insulating tube too much be exposed to air, make insulating tube and cylindrical shell contact area large, send temperature to cylindrical shell, realize the insulation to cylindrical shell, economize on resources further, reduce costs.
