Description

Technical Field

[0001] The invention relates to the technical field of falling film absorbers, and in particular to a falling film graphite absorber. Background Art

[0002] Graphite falling film absorber is a chemical equipment used for mass transfer and reaction between gas and liquid. It uses the tiny holes and capillary action formed on the surface of the graphite plate to evenly distribute the liquid on the graphite plate to form a thin film layer. The thin film layer adsorbs the substances in the gas to the surface of the graphite plate, and then washes the adsorbed substances off the graphite plate through the flow of liquid, thereby realizing gas-liquid mass transfer and reaction. The tiny holes and capillary action on the surface of the graphite plate make the adsorption and mass transfer process very efficient, and the graphite material has excellent chemical stability and thermal stability, and can operate stably in various harsh environments.

[0003] A Chinese patent (CN220758607U) discloses a mist-reducing graphite falling film absorber, comprising a first treatment box, a second treatment box is arranged below the first treatment box, a graphite tube is arranged inside the second treatment box, a first side plate is arranged on one side of the second treatment box, a mist inlet pipe is arranged on one side of the first side plate, a second side plate is arranged on the other side of the second treatment box, a mist outlet pipe is arranged on one side of the second side plate, and an air inlet pipe is arranged on the inner side of the first treatment box. The falling film absorber generates a swirl flow by contacting the gas with the inner wall of the first treatment box, and the contact area between the gas and the graphite tube is increased by the horizontal structure of the graphite tube, thereby facilitating the treatment of increasing the contact area between the gas and the graphite material in the falling film absorber.

[0004] Although the above patent can adsorb impurities in the gas, the graphite tube is fixedly arranged. When the gas passes through the graphite tube wall, the contact area is always the left and right end faces of the graphite tube. The front and rear end faces of the graphite tube cannot be well utilized, and the contact area between the gas and the graphite tube is limited. Moreover, the absorption liquid sprayed from the mist outlet pipe corresponds to the middle graphite tube. The absorption liquid enters the graphite tube to form a film, but most of the absorption liquid enters the middle graphite tube, and less absorption liquid enters the absorption tubes on the left and right sides. The film-forming property is poor and the absorption liquid is unevenly distributed. Since the graphite tube plays the role of adsorbing impurities, the impurities cannot be completely taken out by liquid flow alone. When cleaning the inner wall of the graphite tube in the above patent, the equipment needs to be disassembled, the inner wall of the graphite tube needs to be cleaned, and the graphite tube needs to be installed after cleaning. The operation is cumbersome and the cleaning efficiency is low.

[0005] Therefore, the present invention provides a falling film graphite absorber to solve the above problems. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a falling film graphite absorber to solve the problems of limited contact area between gas and graphite tube, uneven distribution of absorption liquid in the graphite tube, and cumbersome operation when cleaning the inner wall of the graphite tube.

[0050] The motor 21 is turned on, and the motor 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the first driving gear 23 to mesh with the rotating gear 19. The rotating gear 19 drives the graphite tube 5 to rotate, so that the multiple graphite tubes 5 rotate synchronously. The absorption liquid flowing out of the diverter 11 is evenly coated on the inner wall of the graphite tube 5 as the graphite tube 5 rotates to form a thin film. The air supply device is connected with the air inlet pipe 3, and the collecting device is connected with the exhaust pipe 4. When the gas passes through the graphite tube 5, the impurities in the gas are adsorbed by the absorption liquid forming the thin film. Because the graphite tube 5 is always in a rotating state, the gas is fully in contact with the inner wall of the graphite tube 5, and the impurities in the gas can be absorbed more thoroughly. The purified gas is discharged and collected through the exhaust pipe 4. The absorption liquid in the graphite tube 5 flows into the collecting tank 16 under the action of gravity. After the gas purification is completed, the motor 21 is turned off;

[0051] When the inner wall of the graphite tube 5 needs to be cleaned, the handle 29 is pulled backward, the handle 29 drives the cylinder 28 to move backward and stretch the third spring 32, the cylinder 28 drives the block 31 to move out of the limit block 30, and the limit on the cylinder 28 is released, so that the first spline of the cylinder 28 drives the circular shaft 27 to rotate, the circular shaft 27 drives the guide plate 26 to rotate, the circular shaft 27 drives the swing rod 35 to swing downward, the swing rod 35 drives the connecting plate 33 to move downward through the plug column 36 and the waist-shaped groove 34, the connecting plate 33 drives the moving block 20 and the rotating shaft 22 to move downward, the moving block 20 drives the rotating shaft 22 to move downward, the rotating shaft 22 drives the first driving gear 23 downward to disengage from the rotating gear 19, when the cylinder 28 is closed, the cylinder 28 is opened. When the cylinder 28 drives the block 31 to swing to the limit block 30 on the left, under the reset force of the third spring 32, the cylinder 28 drives the block 31 to be inserted forward into the limit groove on the left, and the guide plate 26 is in an inclined state with the left lower and the right higher. At this time, the liquid delivery pipe 15 on the right is connected with the vertical pipe 13 at the lower end of the round box 12, and the moving block 20 moves downward to the limit position. The moving block 20 drives the second driving gear 47 to mesh with the driven gear 43 through the rotating shaft 22. The cleaning liquid in the liquid storage tank 14 on the right flows into the round box 12 under the action of gravity, and the cleaning liquid flows into the flow equalizing box 6 through the vertical pipe 13. As can be seen from the above, the cleaning liquid flows evenly into each graphite tube 5 through the flow equalizing box 6;

[0052] When the motor 21 is turned on and the motor 21 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the second driving gear 47 to mesh with the driven gear 43, so that the rotating shaft 42 rotates, and the rotating shaft 42 drives the rotating plate 45 to rotate around the rotating shaft 42 through the rotating rod 44, and the rotating plate 45 drives multiple swinging rods 46 to swing, and the swinging rod 46 drives the reciprocating screw 37 on the corresponding side to rotate, and the reciprocating screw 37 drives the slider 38 on the corresponding side to move up and down through the screw nut 39, and the slider 38 drives the cleaning plate 17 to move up and down through the ring 40, and the reciprocating screw 37 drives the cleaning plate 17 to move up and down. The lead screw 37 drives the guide shaft 41 to rotate, and the guide shaft 41 drives the cleaning disc 17 to rotate via the second spline, so that the cleaning disc 17 moves up and down and rotates at the same time, and the cleaning disc 17 drives the cleaning brush 18 to move up and down and rotates at the same time to clean the inner wall of the graphite tube 5, and the waste liquid after cleaning flows into the collecting tank 16 to be collected. After cleaning, the cleaning disc 17 moves downward to the initial position and the motor 21 is turned off. When it is necessary to discharge the waste liquid in the collecting tank 16, the valve 51 is opened, and the waste liquid in the collecting tank 16 is discharged through the drain pipe 50.
