NOZZLE FOR A VERTICAL CHEMICAL REACTOR

摘要

The invention relates to chemical equipment, in particular to the internal arrangement of chemical reactors used for processing in a gas liquid medium, and can be used for example, for synthesizing karbamide from ammonia and carbon dioxide at high temperature and pressure. The inventive nozzle comprises perforated separating baffles (7) and (8) and tubular contacting devices (9) fixed to a supporting grid (13) by the upper ends thereof. The contact device (9) comprises vertical tubular circular-section elements i. e. One descending element (10) and one lifting element (11) connected to each other in a lower part thereof with the aid of a U-tube element (12). The descending element (10) is fitted with an orifice (14) and an orifice (15) forsupplying gas and fluid, whereas the lifting element (11) is fitted with an orifice (17) embodied in the supporting grid for the output of a gas-liquid mixture. A short shell (18) is fixed to the bottom of the supporting grid and creates an air-cushion enabling the
