Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid deodorization and decolorization treatment, and particularly relates to a deodorization and decolorization device and process. BACKGROUND

[0002] Under the background of circular economy, many chemical enterprises will recycle solvents, lubricating oils and other materials. These materials are often contaminated after use, the color becomes deep, and have irritating odor, and must be deodorized and decolorized before being reused. In the prior art, a color removing agent and a deodorizing agent are usually added to the original liquid, and the mixed solution is stirred to make the original liquid fully react with the color removing agent and the deodorizing agent, so as to realize the deodorization and decolorization treatment of the original liquid.

[0003] In order to enhance the chemical reaction rate and efficiently remove odor substances and pigments, the prior art usually puts the original liquid, the color removing agent and the deodorizing agent into a supergravity rotating bed for reaction. The supergravity rotating bed is an innovative chemical process equipment. It generates a strong centrifugal force through high-speed rotation to greatly strengthen the mass transfer, heat transfer and reaction process.

[0004] The supergravity rotating bed comprises a shell, a baffle type rotor and a liquid distributor. The baffle type rotor usually comprises a dynamic baffle ring and a static baffle ring which are concentrically and staggeringly nested. The dynamic baffle ring is connected with the main shaft and rotates at high speed with the rotor. The static baffle ring is fixed with the shell and is stationary. When working, the liquid enters the inner edge of the rotor and is “captured” by the high-speed rotating dynamic baffle ring and is accelerated to be thrown to the outside. After being thrown out, the liquid hits the stationary static baffle ring and is broken up violently. Then, the liquid on the static baffle ring is captured, accelerated and thrown out again by the rotating dynamic baffle ring of the next stage. This process can exert extreme shear force on the liquid and disperse it into micron or nanometer level, so as to realize uniform mixing of the original liquid and the reaction reagent.

[0005] A supergravity rotating bed with a composite rotor disclosed in a patent with the authorized announcement number CN106178573B comprises a shell, a static disc, a liquid inlet pipe arranged at the center above the static disc, a capillary liquid outlet hole arranged on the pipe wall of the liquid inlet pipe in the shell, a composite rotor which is arranged coaxially with the static disc and passes into the shell from the lower end of the shell upward, the composite rotor comprising concentrically distributed dynamic baffle rings, the static disc having concentrically distributed static baffle rings downward, the dynamic baffle rings and the static baffle rings being nested with each other, the innermost layer of the composite rotor being provided with a plurality of corrugated disc plates which are uniformly distributed from top to bottom, the corrugated disc plates being provided with through holes, the corrugated disc plates being fixed outside the liquid inlet pipe, a liquid outlet being arranged below the shell, a gas inlet being arranged on the sidewall of the shell, and a gas outlet being arranged outside the liquid inlet pipe above the static disc.

[0006] Since the original liquid and the deodorizing agent and the decoloring agent will produce flocculation when reacting, impurities will be attached to the surface of the static baffle and the dynamic baffle after the equipment is used for a long time. In the prior art, for general impurities, the equipment can be cleaned automatically by adding cleaning agent and clean water into the equipment and rotating the rotor at high speed. However, for impurities with strong adhesion, the rotor needs to be disassembled and manually cleaned. This cleaning method involves disassembling and reassembling the equipment, and is complicated, time-consuming, labor-intensive, high in labor cost and low in efficiency. SUMMARY

[0007] The application provides a deodorizing and decoloring device to solve the technical problem of complicated cleaning steps and low cleaning efficiency of the supergravity rotating bed for accelerating the deodorizing and decoloring reaction efficiency in the prior art.

[0053] The sealing body 19 is annular and coaxially mounted on the inner wall of the cylindrical body 1 and positioned within the working chamber. The inner diameter of the sealing body 19 is identical to the outer diameter of the fixed plate 21. When the fixed plate 21 and the movable plate 11 are engaged and in operation, the sealing body 19 is positioned below the fixed plate 21.

Figure 3 、 Figure 9 As shown, a feeding auger 20 is rotatably installed in the temporary storage chamber, and the top and bottom ends of the feeding auger 20 are connected to a ring-shaped rotating plate 26. The two rotating plates 26 are adapted to be rotatably installed in the temporary storage chamber and are in contact with the top side wall and bottom side wall of the temporary storage chamber respectively.

[0055] A limiting member 25 is also connected to the inner wall of the blocking body 19 . The limiting member 25 is a circular flat plate. The inner diameter of the limiting member 25 is smaller than the outer diameter of the fixed plate 21 and larger than the outer diameter of the baffle 22 .

The cleaning plates 28 are arc-shaped, and the outer ends of the cleaning plates 28 are connected to the aforementioned rotating plate 26 at the bottom. The bottom end of the rotating sleeve 29 extends through the bottom sealing plate 23 and between the bottom sealing plate 23 and the support plate 24. When the rotating sleeve 29 rotates, it drives the cleaning plates 28 to rotate. The cleaning plates 28 drive the feed auger 20 to rotate through the rotating plate 26.

The lifting cylinder 15 has a drive output end that can move up and down. The drive output end of the lifting cylinder 15 passes through the middle of the above-mentioned bottom sealing plate 23 and the filter screen 27 and is connected to the baffle 22. The lifting cylinder 15 can drive the baffle 22 to move up and down, thereby driving the fixed plate 21 and the static baffle ring 13 connected to the fixed plate 21 to move up and down. When the fixed plate 21 is in the working state, the lifting cylinder 15 keeps the fixed plate 21 at a top limit position and does not move.
