The invention discloses a benzene partial hydrogenation reaction catalyst separation device in the production process of cyclohexanone, and belongs to the technical field of benzene partial hydrogenation reaction catalyst separation. A catalyst separation device for benzene partial hydrogenation reaction in the production process of cyclohexanone, comprising a first installation box, and further comprising: a second installation box fixedly connected in the first installation box; the present invention separates the hot air through ventilation components It is sent into the first jet box, the second jet box and the third jet box, and the three groups of jet boxes spray high-pressure gas, which are blown to the upper holes of the filter cylinder, the first screen cylinder and the second screen cylinder, which are located at the top in real time, Make the air flow into the cylinder from the outside, and blow off the catalyst blocked on the holes, so as to prevent the catalyst particles from blocking the sieve holes and filter holes and accelerate the volatilization of the water vapor in the first and second sieve cylinders by the blown hot air. Therefore, the catalyst is quickly dried, a large amount of heat energy is avoided when the catalyst is separated in the partial hydrogenation reaction of benzene, and the utilization rate of energy is improved. |
