Description

TECHNICAL FIELD

[0001] The application relates to the technical field of activated carbon, in particular to a processing method and equipment for honeycomb activated carbon material based on titanium modification. BACKGROUND

[0002] The honeycomb activated carbon composite material based on titanium modification is a functional composite material for optimizing the performance of honeycomb structure activated carbon by titanium compounds (such as titanium dioxide, titanate, etc.), which combines the high adsorption capacity of honeycomb activated carbon and the special chemical properties (such as photocatalysis, antibacterial property, stability, etc.) of titanium materials, and has important application value in the fields of environmental purification and catalytic reaction.

[0003] The key of titanium modification is to uniformly and stably load titanium substances on the honeycomb activated carbon. The common process is impregnation, that is, the honeycomb activated carbon is soaked in a titanium solution (such as an ethanol solution of tetrabutyl titanate), and the titanium substances penetrate into the pores through capillary action, and then are dried and calcined (such as 400-600 DEG C) to form titanium oxide particles. Because the surface of the honeycomb activated carbon usually remains dust particles, ash or unactivated organic matter; therefore, the honeycomb activated carbon is usually soaked in deionized water or dilute acid (such as 1-5% HCl) or dilute alkali (such as 1-5% NaOH) before titanium modification, wherein the acid washing can dissolve mineral impurities, and the alkali washing can neutralize the acidic residues to avoid the reaction of the acidic residues with the titanium precursor (such as tetrabutyl titanate) to generate precipitates and block the pores. Subsequently, the surface of the honeycomb activated carbon is further cleaned by a conventional physical cleaning method (such as vibration cleaning), and then is dried for use.

[0004] Although the above method can effectively remove the dust, impurities and acidic residues on the surface of the honeycomb activated carbon, the tar-like substances in the pores of the honeycomb activated carbon cannot be effectively removed by the above treatment method, and the tar-like substances in the pores hinder the connectivity of the pores, which is not conducive to the subsequent penetration of the impregnation solution.

DETAILED DESCRIPTION

[0027] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined object of the application, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0028] Embodiment: Please refer to Figures 1-4The application discloses a processing device for honeycomb activated carbon material based on titanium modification, which comprises a steam tank 3 communicated with a gas outlet pipe of a steam generator, a steam spraying frame 12 arranged in the steam tank 3, a steam-mechanical energy conversion mechanism 4 communicated with a pressure relief opening of the steam tank 3 and a carbon storage net frame arranged in the steam tank 3 and used for storing honeycomb activated carbon with a water content of 5%-10%. One end of the steam spraying frame 12 is connected with the gas outlet pipe through a rotary joint 19, the other end of the steam spraying frame 12 is rotationally connected with the steam tank 3 and penetrates the steam tank 3, the end of the steam spraying frame 12 penetrating the steam tank 3 is connected with an output end of the steam-mechanical energy conversion mechanism 4, and a gas outlet of the steam spraying frame 12 is directed to a side wall of the carbon storage net frame. The steam-mechanical energy conversion mechanism 4 converts the energy of steam into energy for rotating the steam spraying frame 12. The steam generator can be a common device capable of generating high-temperature steam, and the steam-mechanical energy conversion mechanism 4 can be in the form of a steam turbine. The output end of the steam turbine can be connected with the steam spraying frame 12 through a synchronous belt transmission mechanism, so that the steam spraying frame 12 can be rotated by using the kinetic energy and thermal energy of steam, thereby realizing uniform spraying of the honeycomb activated carbon in the carbon storage net frame. In the process of spraying the honeycomb activated carbon by using high-temperature steam, the steam activates the honeycomb activated carbon, thereby opening the blocked micropores and mesopores on the surface of the honeycomb activated carbon, expanding the pore channel and enabling the steam to slightly react with carbon on the surface of the honeycomb activated carbon, thereby removing tar substances in the pore channel, improving the connectivity of the pore channel and facilitating deep penetration of the impregnation liquid. The steam-mechanical energy conversion mechanism 4 avoids the use of an additional driving motor, saves cost, enables the steam in the steam tank 3 to flow, guarantees the activation quality of the honeycomb activated carbon by the steam in the steam tank 3 and fully utilizes the thermal energy and kinetic energy of the steam, thereby converting the thermal energy and kinetic energy of the steam into kinetic energy of the steam spraying frame 12 and preventing energy waste.

[0029] Furthermore, controlling the initial moisture content of the honeycomb activated carbon at 5%-10% ensures that during steam activation, two key aspects are addressed: First, the residual moisture in the pores (especially adsorbed bound water) rapidly vaporizes at high temperatures, participating in the etching reaction (C+H2O→CO+H2) together with the externally introduced high-temperature steam. This moisture acts as an "internal activator," synergistically enhancing the etching effect with the external steam and reducing the initial consumption of external steam. Second, if the activated carbon is completely dry, uneven heat conduction at high temperatures may lead to localized melting of the carbon skeleton (especially above 800℃), thus causing… This can lead to pore blockage; the endothermic effect of a small amount of water vaporization can buffer local temperature peaks, making the activation reaction more uniform; in addition, experiments have shown that if the water content is too high, such as greater than 10%, then the excessive water vaporization at high temperature will consume a lot of heat energy (1 kg of water vaporizes from 20°C and heats up to 800°C, which requires about 3000 kJ of energy), which will reduce the actual heat used for the etching reaction, thereby prolonging the time to reach the target activation temperature (potentially increasing energy consumption by 10%-20%); preferably, in this embodiment, controlling the initial water content at 8% will result in more significant of the above-mentioned beneficial effects.

[0030] In this embodiment, the cross-section of the carbon storage mesh frame is annular. The sidewalls of the carbon storage mesh frame include an inner wall 35 and an outer wall 34. Both the inner wall 35 and the outer wall 34 are mesh sidewalls, which facilitate the entry of steam while preventing the honeycomb activated carbon from falling out. The steam spray frame 12 includes a plurality of external spray pipes 7 circumferentially distributed outside the outer wall 34 and a plurality of internal spray pipes 8 inside the inner wall 35. The nozzles of the external spray pipes 7 are oriented in the direction pointing towards the axis of the carbon storage mesh frame, and the nozzles of the internal spray pipes 8 are oriented in the direction away from the axis of the carbon storage mesh frame. By combining the steam injection directions from the inside to the outside and from the outside to the inside, the situation of unsatisfactory local activation effect caused by unidirectional injection is avoided, which greatly improves the activation quality and thus improves the connectivity of the pores.

[0031] In addition, the steam spray frame 12 also includes a gas distribution chamber 13 connected to the rotary joint 19 and several bottom spray pipes 9 connected to the gas distribution chamber 13. The nozzles of the bottom spray pipes 9 are oriented towards the bottom of the carbon storage mesh frame to achieve vertical spraying of the honeycomb activated carbon, thereby improving the uniformity of steam spraying onto the honeycomb activated carbon in all directions. The end of the bottom spray pipe 9 away from the gas distribution chamber 13 is connected to several outer spray pipes 7 and several outer gas equalization pipes 10. The several outer spray pipes 7 and several outer gas equalization pipes 10 are staggered, and the ends of the several outer spray pipes 7 and several outer gas equalization pipes 10 away from the bottom spray pipe 9 are connected through an outer ring pipe 11 and through an outer gas equalization pipe 10. The outer ring pipe 11 and the outer ring pipe 29 improve the consistency of the air output at the upper and lower parts of the outer nozzle 7, reducing the situation where the air output at the end of the outer nozzle 7 near the gas distribution chamber 13 is much higher than the air output at the end away from the gas distribution chamber 13, thus ensuring uniform spraying of steam onto the honeycomb activated carbon. Similarly, the top of the gas distribution chamber 13 is connected to the transition pipe 2, which is connected to several inner nozzles 8 and several inner equalization pipes. The several inner nozzles 8 and several inner equalization pipes are staggered, and the ends of the several inner nozzles 8 and several inner equalization pipes away from the gas distribution chamber 13 are connected through the inner ring pipe 29, further ensuring uniform spraying of steam onto the honeycomb activated carbon.

[0032] In this embodiment, one end of the rotating shaft 5 of the steam sprayer 12 is fixed to the outer wall of the inner spray pipe 8 and the inner gas equalization pipe, and the other end is connected to the output end of the steam-mechanical energy conversion mechanism 4. The upper part of the rotating shaft 5 is fixed to the stirring frame 6 through the crossbar 33. The crossbar 33 is located between the top of the inner wall 35 and the inner top of the steam tank 3. The stirring frame 6 is located inside the carbon storage mesh frame between the inner wall 35 and the outer wall 34. The stirring frame 6 is composed of several vertical rods and several crossbars 33. Therefore, when the rotating shaft 5 rotates, it realizes the rotation of the steam sprayer 12 and the stirring of the honeycomb activated carbon, so that the honeycomb activated carbon can be sprayed with steam in all directions, improving the activation quality of the honeycomb activated carbon and thus improving the connectivity of the pores.

[0033] Furthermore, although the steam spray frame 12 can rotate in this embodiment, since the nozzles of the steam spray frame 12 are always at a specified height, the activation quality of the honeycomb activated carbon between adjacent nozzles is inevitably lower than that of the nozzles aligned. To address this issue, in this invention, an elastic reciprocating mechanism is provided between the steam spray frame 12 and the rotary joint 19. A reciprocating screw 24 is provided at the upper part of the rotating shaft 5, and a movable seat 32 is connected to the reciprocating screw 24. A limiting mechanism for restricting the rotation of the movable seat 32 is provided between the movable seat 32 and the inner wall 35. An anti-friction component is provided at the bottom of the movable seat 32. When the movable seat 32 reciprocates, the inner ring tube 29 is always in contact with the anti-friction component under the action of the elastic reciprocating mechanism. The lower part of the rotating shaft 5 is a square shaft 14, and a drive shaft 28 is provided at the bottom of the reciprocating screw 24. The square hole of 8 is slidably connected to the square shaft 14. Therefore, when the rotating shaft 5 rotates, the reciprocating screw 24 will rotate, thereby causing the moving seat 32 to reciprocate. When the moving seat 32 moves upward, the steam sprayer 12 moves upward under the action of the elastic reciprocating mechanism. When the moving seat 32 moves downward, the anti-friction component moves downward, thereby pushing the steam sprayer 12 downward. At this time, the elastic reciprocating mechanism stores energy. Therefore, during the reciprocating movement of the moving seat 32, the steam sprayer 12 will also reciprocate in the vertical direction, thereby realizing the reciprocating movement of the nozzle, and thus realizing the spraying of honeycomb activated carbon between two adjacent nozzles. In addition, in this embodiment, the distance between two adjacent nozzles is less than the one-way distance of the reciprocating movement of the moving seat 32, thereby ensuring that all the honeycomb activated carbon inside the carbon storage mesh frame is sprayed.

[0034] In this embodiment, the limiting mechanism includes a limiting ring fixed to the top of the inner wall 35 and several limiting rods 26 fixed to the side wall of the movable seat 32. The limiting ring is provided with several vertical slots 25. The ends of the limiting rods 26 pass through the vertical slots 25 and abut against the two side walls of the vertical slots 25 on the outer edge of the limiting rods 26, thereby limiting the rotation of the movable seat 32 and ensuring that the movable seat 32 can only reciprocate in the vertical direction. The anti-friction component includes a bottom plate 30 fixed to the top of the inner ring tube 29, a top plate 27 fixed to the limiting rods 26, and several rollers 31 circumferentially distributed at the bottom of the top plate 27. Under the action of the elastic reciprocating mechanism, the bottom plate 30 always abuts against the outer circle of the rollers 31, thereby reducing the friction generated when the steam spray frame 12 rotates and ensuring the stability of the steam spray frame 12 during rotation and up-and-down reciprocating motion.

[0035] The elastic reciprocating mechanism includes a cylinder 22 fixed to the opposite end of the rotary joint 19 and a piston rod 18 slidably connected to the inside of the cylinder 22. The connection between the two can adopt the connection form of the cylinder 22 and piston rod 18 when it is resistant to high temperatures, such as the cylinder 22 and piston that constitute the combustion chamber in an automobile. The difference is that the inside of the cylinder 22 in this invention is connected to the exhaust pipe, the top of the piston rod 18 is fixed to the air distribution chamber 13, and the inside of the piston rod 18 is provided with a passage for connecting the inside of the cylinder 22 and the air distribution chamber 13. The piston rod 18 has a first ring plate 23 at the top of the vent 15 and a second ring plate 20 at the bottom of the cylinder 22. The first ring plate 23 and the second ring plate 20 are fixedly connected by several compression springs 21. Therefore, when the moving seat 32 moves downward, it will drive the steam spray frame 12 to move downward. During this process, the compression springs 21 will be squeezed, so that the compression springs 21 will undergo elastic deformation and store energy. When the moving seat 32 moves upward, the springs release energy, thereby pushing the steam spray frame 12 to move upward, thus realizing the reciprocating movement of the steam spray frame 12.

[0036] In addition, a sleeve is fixedly connected to the first ring plate 23, and a guide rod 16 that mates with the sleeve is fixedly connected to the second ring plate 20. The guide rod 16 passes through the sleeve, and a frustum 17 with the same diameter as the outer circle of the sleeve is fixedly connected to one end of the guide rod 16. One end of the compression spring 21 is sleeved on the sleeve, and the other end of the compression spring 21 is sleeved on the frustum 17. When the steam spray frame 12 moves to the lowest position, the end face of the frustum 17 abuts against the end face of the sleeve, thereby ensuring that the force on the compression spring 21 is along the axial direction, while ensuring the synchronous rotation of the first ring plate 23 and the second ring plate 20, thus ensuring... This ensures the synchronous rotation of the piston rod 18 and the cylinder 22, preventing wear between the piston rod 18 and the cylinder 22 caused by relative rotation when the steam sprayer 12 rotates. At this time, the rotation point is the rotary joint 19, and the wear is normal wear. In addition, the rotary joint 19 and the spring are made of high-temperature resistant materials and structures, which is an adaptation adjustment of conventional technology and will not be elaborated on in this article. Four circumferentially distributed opening and closing doors 1 are provided on the top of the steam tank 3 for the insertion and removal of honeycomb activated carbon.

[0037] Working principle: First, honeycomb activated carbon with an initial moisture content controlled at 5%-10% is placed inside the carbon storage mesh frame. Then, the steam generator is started, and steam enters the steam spray frame 12 through the exhaust pipe and is sprayed out from the nozzles in the outer spray pipe 7, inner spray pipe 8, and bottom spray pipe 9, thereby activating the honeycomb activated carbon in the carbon storage mesh frame. When the gas pressure inside the steam tank 3 reaches the set pressure, steam flows into the steam-mechanical energy conversion mechanism 4 from the pressure relief port. The steam-mechanical energy conversion mechanism 4 drives the rotating shaft 5 to rotate. At this time, the square shaft 14 and the stirring frame 6 rotate, thereby driving the steam spray frame 12 to rotate around the rotary joint 19 as the rotation center. At the same time, the stirring frame 6 stirs the honeycomb activated carbon in the carbon storage mesh frame. During this process, the reciprocating screw 24... Rotation also occurs, causing the movable seat 32 to reciprocate vertically. When the movable seat 32 moves downward, it drives the steam sprayer 12 downward, compressing the compression spring 21 during this process. This causes the compression spring 21 to undergo elastic deformation and store energy. When the movable seat 32 moves upward, the spring releases energy, thereby pushing the steam sprayer 12 upward, thus realizing the reciprocating movement of the steam sprayer 12. Therefore, this invention utilizes steam to drive the steam sprayer 12 to spray honeycomb activated carbon while simultaneously rotating and reciprocating up and down. This achieves comprehensive spraying of the honeycomb activated carbon inside the carbon storage frame, fully activating all the honeycomb activated carbon and greatly improving the connectivity of the honeycomb activated carbon pores.

[0038] Furthermore, this invention also discloses a processing method for titanium-modified honeycomb activated carbon materials, mainly utilizing the aforementioned processing equipment for titanium-modified honeycomb activated carbon materials, including the following steps:

[0039] Step 1: Place the honeycomb activated carbon, which has been vibrated, cleaned, acid-alkali soaked, and dried to a moisture content of 5%-10%, into the carbon storage mesh frame. Vibration cleaning is performed using ultrasonic cleaning, where the honeycomb activated carbon is placed in deionized water at an ultrasonic power of 300-500W for 15-30 minutes to remove surface dust and debris. Acid-alkali soaking mainly involves: acid washing: soaking in 5% HCl solution for 2 hours (room temperature) to remove metal oxide impurities; alkali washing: soaking in 2% NaOH solution for 1 hour (room temperature) to neutralize acidic residues. Drying is performed using common drying equipment, ensuring that the moisture content of the honeycomb activated carbon is 5%-10% after drying.

[0040] Step 2: Start the steam generator and spray steam through the steam sprayer 12 onto the carbon storage mesh frame to remove tar-like substances from the pores of the honeycomb activated carbon and expand the pore size at the same time.

[0041] Step 3: In step 2, when the internal pressure of the steam tank 3 reaches the set pressure, steam flows from the pressure relief port into the steam-mechanical energy conversion mechanism 4. The steam-mechanical energy conversion mechanism 4 will drive the steam spray frame 12 to rotate, thereby achieving uniform spraying of honeycomb activated carbon.

[0042] Step 4: After processing in Step 2 for 1-2 hours, cool down to 50-60℃ and then immerse the honeycomb activated carbon in a titanium-based solution for titanium modification. Before immersion, the honeycomb activated carbon can also be oxidized by immersing it in a 30% H2O2 solution for 2 hours (50℃) to introduce polar groups such as hydroxyl and carboxyl groups; or by ozone oxidation (concentration 5-10 mg / L, treatment for 30 minutes). Among these, polar functional groups such as hydroxyl (-OH) and carboxyl (-COOH) can form hydrogen bonds or coordination with titanium-based precursors (such as tetrabutyl titanate), enhancing the adsorption capacity of titanium-based solutions and promoting the diffusion of titanium-based substances into the pores.
