Description

Technical Field

[0001] The utility model relates to the technical field of diene ketone acetate, in particular to an automatic cooling device for diene ketone acetate. Background Art

[0002] The main characteristics of dienol ketone acetate are white crystalline powder, no peculiar smell, no taste, and easy to dissolve in ethanol and methanol, but insoluble in water, and stable in the air; a reactor is required for the reproduction of dienol ketone acetate. Since the reactants of dienol ketone acetate will generate high temperature during the reaction, the temperature inside the reactor of dienol ketone acetate will rise rapidly, which requires the outer wall of the reactor to be cooled. In order to prevent the outer wall of the reactor from cracking due to rapid cooling, water cooling is generally used. However, the current water cooling has a limited cooling range and can only cool the range where water pipes are laid, which requires a long time for conduction, and the large amount of water consumption is easy to waste resources;

[0003] In this regard, the Chinese patent publication number CN211876498U discloses "an automatic cooling device for the production of dienol ketone acetate, comprising a reaction container, the outside of the reaction container is fixedly connected to a shell, the left and right walls of the inner cavity of the shell are fixedly connected to a fixing plate, the inner side of the fixing plate is fixedly connected to a fixing frame, the right side of the reaction container is fixedly connected to a fixing ring, the inside of the fixing ring is fixedly connected to a guide pipe located outside the reaction container, the right side of the shell is fixedly installed with a booster pump, the right side of the booster pump is fixedly installed with a control module, and the water outlet of the booster pump is fixedly connected to one end of the guide pipe";

[0004] This patent introduces cooling water into the interior of a "flow guide tube" through a "boosting pump", then sprays the cooling water toward the "reaction vessel" through a "nozzle" on the "flow guide tube" for cooling, and finally the cooling water is discharged through a "liquid outlet pipe". When the "nozzle" sprays out cooling water, the cooling water adheres to the outer wall of the "reaction vessel", and then flows out vertically downward rapidly under the action of gravity, which shortens the contact time between the cooling water and the "reaction vessel", and also shortens the cooling effect time of the cooling water on the "reaction vessel", resulting in poor cooling effect of a single water spray, and more cooling water needs to be introduced to achieve the corresponding cooling effect, which results in a waste of resources.

[0026] The water spray assembly 12 includes a plurality of mounting plates 121, which are fixedly mounted on the inner wall of the shell 11 and are equidistantly distributed around the shell 11. A plurality of annular water pipes 122 are fixedly mounted between the mounting plates 121, and the plurality of annular water pipes 122 are equidistantly distributed in the vertical direction. A plurality of nozzles 123 are fixedly mounted on the inner sides of the plurality of annular water pipes 122, and the plurality of nozzles 123 are equidistantly distributed around the corresponding annular water pipes 122. A drain pipe 127 is fixedly mounted on the bottom of the shell 11, and a corresponding opening and closing valve is fixedly mounted on the drain pipe 127. A water inlet pipe 126 is arranged on the outer side of the shell 11, and a corresponding control valve is fixedly mounted on the water inlet pipe 126. A plurality of diverter pipes 125 are fixedly mounted on the water inlet pipe 126, and the outlet ends of the plurality of diverter pipes 125 are respectively connected to the corresponding annular water pipes 122.

[0027] Water is introduced into the water inlet pipe 126 through the water supply component 13, and then introduced into each annular water guide pipe 122 through the diversion pipe 125, and then the water is sprayed onto the outer wall of the reactor 2 through each nozzle 123. At this time, the reactants of diene alcohol ester acetate inside the reactor 2 will exchange heat with the cooling water through the reactor 2, and the water sprayed onto the side wall of the reactor 2 will flow into the spiral water guide plate 3, and finally flow downward along the spiral water guide plate 3.
