MULTIPHASE LIQUID DISTRIBUTOR FOR REACTOR WITH TUBES Russian patent published in 2009 - IPC B01J8/06 B01J10/00 

FIELD: mechanics, chemistry.

SUBSTANCE: proposed device is used for uniform distribution of two liquid phases into multiple tubes of a vertical reactor intended for chemical reactions wherein the internal space of the tubes is intended for performance of operations with a layer incorporating jet liquid streams. Note that these tubes are attached in the top and bottom parts by means of plates and closed on their external side. The distributor contains the distributive chamber located above the top plate containing feed tubes for two various liquid phases and at least one gas phase. Directly above the plate or on it, the first system of liquid distribution is arranged attached to one external feed appliance and has a circular spillway arranged outside the tubes space and furnished with orifices made in its bottom part and with a set of inlet branch pipes. One inlet branch pipe is intended for the top part of each tube of the reactor. Note that the inlet branch pipes have a tubular design, are vertically aligned, have at least one lateral orifice and one orifice located above the plate and are open at the bottom part located opposite an appropriate tube. Above the first distribution system, the second distribution system is located attached to one other external feed appliance, and contains one top and one bottom distributive trays. The bottom distributive tray contains a set of the orifices arranged on one level above inlet branch pipes of the first distribution system, and has at least one appliance setting an identical liquid level above these orifices. The top distributive tray is attached to the liquid feeding appliance and contains a set of spillways for passing liquid in the bottom distributive tray, each spillway being intended for a set of orifices of the bottom distributive tray.

EFFECT: uniform filling of multiple tubes of vertical reactor for chemical or biological reactions.
