FIELD: manufacturing technology.
SUBSTANCE: invention relates to tray (4) of reactor for producing urea. Tray comprises at least one base plate (10) and multiple hollow bowl-shaped elements (11, 11A), which extend vertically from base plate (10) along respective substantially parallel axis (A) perpendicular to base plate (10), and have appropriate substantially concave internal cavities (17, 37), communicating with appropriate holes (15) formed in base plate (10). At that, tray (4) comprises multiple first bowl-shaped elements (11), extending downward from lower side (14) of base plate (10), and each of which passes axially between open upper end (21), having hole (15), and closed lower end (22). Each first bowl-shaped element (11) comprises side wall (23) with through circulation holes (25), arranged substantially across axis (A) and intended for preferred through flow of gas phase and/or liquid phase; and bottom wall (24), which closes closed lower end (22) and has no circulating holes. At that, side wall (23) of each of first bowl-like element (11) has first circulation holes (25A) substantially for through flow of gaseous phase and second circulation holes (25B) substantially for through passage of liquid phase, all substantially across axis (A). First holes (25A) are located closer to open top end (21) than second holes (25B), and first holes (25A) are smaller than second holes (25B). Invention also discloses reactor for producing urea and method of producing urea.
EFFECT: invention provides thorough mixing of gaseous and liquid phases and high output of urea.
