Background
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information constitutes prior art that is already known to a person skilled in the art.
In the hydration reaction of cyclohexanol, cyclohexene refined by hydrogenation reaction enters a hydration reactor of cyclohexanol through the temperature rise of a hydration refining system, and reacts with desalted water under the catalysis of a catalyst (zeolite molecular sieve) to generate cyclohexanol. Prolonged operation of the hydration reactor can lead to reduced catalyst activity and, in addition, to loss of a portion of the catalyst due to the greater cyclohexene flow through the hydration reactor. To avoid deactivation of the catalyst, it is necessary to run a regeneration of the hydrated catalyst to maintain the catalyst activity; while in order to maintain the amount of catalyst participating in the reaction in the hydration reactor, fresh catalyst needs to be added to achieve make-up.
In actual operation, the inventor finds that because a hydration catalyst (zeolite molecular sieve) is a slag slurry, a diaphragm pump is adopted to convey materials according to material characteristics, continuous force generation cannot be realized due to the acting characteristic of the diaphragm pump, a certain idle period can be generated in the pump head acting process, then force generation acting is performed, the situation can cause vibration of a pipeline, certain damage is caused to the service life of the pipeline, equipment flanges and valves connected with the pipeline, and even leakage accidents occur. In the prior art, 0.5 liter buffer tank is installed at the import and the exit of diaphragm pump, because the pump delivery line sets up the problem, causes the pipeline to produce the pulling force easily, causes the pipeline to rock at the pump work in-process, and then causes flange or the mouth of pipe to appear unusually.
In addition, because the regeneration of the cyclohexanol hydration catalyst is intermittent regeneration, and the conveyed medium is a granular material, the work of the pump is reduced along with the lapse of time, and the reduced work can cause serious pipeline surge and is more unfavorable for stable operation.
