Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
Former ketone tower distributor is traditional design, and liquid distributes in the reaction tower inhomogeneously, and production efficiency is lower, and the cyclohexanone quality of producing is relatively poor, reforms transform ketone tower distributor now, adopts an improvement homogeneity ability's tower tray distributor, can improve 10% production load at least on current basis, guarantee that the product quality under the high load is better, reduce ton ketone steam consumption 1 ton simultaneously.
