A kind of deactivated Raney nickel catalyst green recovery treatment device and recovery method

Abstract

A green recovery treatment device and recovery method for deactivated Raney nickel catalyst, including a vertical cylinder body and a liquid distribution kettle, an annular pipe is installed on the upper part of the cylinder body, the annular pipe is installed obliquely, and several connecting pipes are connected to the lower part of the annular pipe The connecting pipe is connected to the upper end of the cylinder, and the connecting pipe extends into the cylinder to cooperate with the inner wall of the cylinder. Several electromagnets are evenly installed on the outer circumference of the cylinder, and the liquid outlet of the liquid mixing kettle is connected to the upper inlet of the annular pipe. The bottom of the body is installed with a pump, the pump is connected to the liquid inlet of the liquid distribution kettle, the upper part of the body is equipped with a CO inlet with a valve, and the bottom of the body is equipped with a discharge pipe with a valve. In the present invention, in the recycling process of the deactivated Raney nickel catalyst, CO and acidic acetic acid which is good for the environment are used for treatment, so as to avoid the use of strong acid and have the advantages of environmental protection.

Description

technical field [0001] The invention belongs to the field of catalyst engineering, in particular to a green recovery treatment device and a recovery method of a deactivated Raney nickel catalyst. Background technique [0002] At present, strong acid is used for stripping in the recovery of deactivated Raney nickel catalyst. Strong acid causes serious environmental pollution and damage, and is highly dangerous. It is difficult to meet the requirements of green recycling production. Using other solutions for stripping takes a long time, slow reaction speed and complicated process. Contents of the invention [0003] The invention provides a deactivated Raney nickel catalyst green recovery treatment device and recovery method, which are used to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A green recovery and treatment device for deactivated Raney nickel catalyst, including a vertical cylin...
