1results about How to "Increase the distribution" patented technology

The utility model relates to the technical field of extraction towers, and discloses a DMF (Dimethyl Formamide) recovery extraction tower based on a metal pore plate filler, which comprises an extraction tower shell, a feeding pipe and a liquid inlet pipe are arranged on the upper part of the surface of the extraction tower shell, a gas discharging pipe is arranged on the upper surface, and a liquid discharging pipe is arranged on the lower part; the metal pore plate filler layer is arranged in the inner cavity of the shell, so that the mass transfer area can be increased, two extracted phases are contacted more fully, and the extraction efficiency is improved. The spraying frame is installed at the liquid outlet end of the liquid inlet pipe, the first nozzles are evenly distributed at the bottom, the inclined second nozzles are installed between the first nozzles, liquid can be sprayed at different angles, the distribution range is enlarged, and the two-phase contact effect is enhanced. A motor is arranged in the middle of the spraying frame, a rotor of the motor is coaxially provided with a rotating plate, cleaning brushes are arranged on the rotating plate corresponding to the nozzles, and when the motor drives the rotating plate to rotate, the cleaning brushes can clean the nozzles, prevent blockage, ensure uniform and stable liquid spraying and maintain normal operation and extraction effect of the extraction tower.
