Description

Technical Field

[0002] Spherical activated carbon has the advantages of good sphericity, uniform packing density, large specific surface area, high strength, wear resistance, corrosion resistance and low resistance when using fixed bed. It is widely used in catalysis, environmental protection, medicine, military, electronics and other fields. Therefore, the preparation and molding research of spherical activated carbon with uniform particle size has been highly valued. Spherical activated carbon produced with phenolic resin as raw material has excellent properties such as low impurity content, high mechanical strength, large surface area, large pore size and easy to control distribution, and large adsorption capacity. Therefore, the preparation of spherical activated carbon materials with phenolic resin as raw material has become one of the main directions of current research and development.

[0003] The existing phenolic resin with uniform particle size distribution is often prepared by a screening method, that is, first, phenol, formaldehyde, a catalyst, a curing agent and a solvent are added to a reactor for suspension polymerization to obtain phenolic resin microspheres; then the phenolic resin microspheres are placed in a rotary furnace, inert gas is introduced to protect them, and then the temperature is increased to 150-250°C at a heating rate of 1-10°C / min, and the temperature is kept for 0-2h to complete curing, and then the inert gas is protected and the temperature is increased to 600-900°C at a heating rate of 3-10°C / min, and the temperature is kept for 0-1h to complete carbonization; then the introduction of inert gas is stopped, and water vapor with a temperature of 200-330°C is introduced for activation treatment, and after the activation is completed, the inert gas is continued to be introduced and the temperature is lowered to 20-25°C to obtain activated carbon microspheres with mixed particle sizes; finally, the activated carbon microspheres with mixed particle sizes are screened using sieves of different mesh sizes to obtain a phenolic resin spherical activated carbon matrix with uniform particle size distribution.

[0004] However, when using the screening method to obtain a phenolic resin spherical activated carbon matrix with uniform particle size, not only are multiple grading processing equipment required to achieve the purpose of screening out particles of different sizes, making the grading process more cumbersome, but the remaining particles after screening are difficult to reuse, resulting in a waste of materials, making the preparation device of the phenolic resin activated carbon matrix insufficiently practical.

[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1

[0051] This embodiment provides a preparation device for a phenolic resin activated carbon substrate, such as Figures 1 to 3 As shown, it includes a water-soluble phase storage component 1, a molding column 2, a spray assembly 3 and a solidifying component 41. Among them, the water-soluble phase storage component 1 is provided with a first outlet 111; the molding column 2 is provided with a first inlet 211; the spray assembly 3 includes an actuator 31, an exciter 32 and a liquid distributor 33, the actuator 31 includes a first connecting end 311, a second connecting end 312 and a third connecting end 313 connected to each other, the second connecting end 312 is connected to the third connecting end 313, the exciter 32 has a driving end and the driving end is connected to the first connecting end 311 to drive the actuator 31 to vibrate regularly, the second connecting end 312 is connected to the first outlet 111, the liquid distributor 33 is provided with a spray plate 331, and the spray plate 331 is evenly provided with discharge holes 332 for connecting the third connecting end 313 with the first inlet 211; the inlet of the solidifying component 41 is connected to the outlet of the molding column 2.

[0052] It can be explained that in the preparation device of the phenolic resin activated carbon matrix provided in this embodiment, the outside of the molding column 2 and the curing part 41 are covered with a jacket, and a hot fluid inlet is provided below the jacket, and a hot fluid outlet is provided above the jacket. In this way, when in use, the hot fluid can enter the jacket from the hot fluid inlet and flow out of the jacket from the hot fluid outlet, thereby achieving heating and insulation of the molding column 2 and the curing part 41, so that the temperature of the liquid phase inside the molding column 2 and the curing part 41 is always maintained within a temperature range suitable for polymerization, thereby facilitating polymerization.

[0053] The preparation device of the phenolic resin activated carbon matrix of this structure connects the first outlet 111, the second connection end 312 and the third connection end 313. After the flow rate is artificially controlled to be constant, the water-soluble phase can flow into the liquid distributor 33 at a constant flow rate, and then the cross-sectional pressure distribution of the water-soluble phase is uniform through the action of the liquid distributor 33. The third connection end 313 is connected to the discharge hole 332 of the injection plate 331, so that the water-soluble phase in the water-soluble phase storage element 1 can flow out from the discharge hole 332 at a constant flow rate; by connecting the exciter 32 to the first connection end 311 of the actuator 31, the water-soluble phase in the water-soluble phase storage element 1 can flow out from the discharge hole 332 at a constant flow rate. The actuator 31 is then driven by the vibrator 32 to vibrate regularly, causing the water-soluble phase to vibrate regularly when flowing out of the discharge hole 332, thereby obtaining water-soluble microspheres with uniform particle size; the water-soluble microspheres with uniform particle size enter the forming column 2 and move from top to bottom, and undergo polymerization reaction during the falling process; when the water-soluble microspheres reach a certain hardness, they are transported to the interior of the curing member 41 for further polymerization reaction, thereby obtaining phenolic resin microspheres with uniform particle size, and subsequently the phenolic resin microspheres with uniform particle size are subjected to carbonization and activation treatment to obtain a phenolic resin activated carbon matrix with uniform particle size. Compared with the existing scheme that requires multiple screening after the phenolic resin activated carbon matrix is ​​formed to obtain a phenolic resin activated carbon matrix with uniform particle size, the preparation device of this structure can directly obtain phenolic resin microspheres with uniform particle size during the forming process, and then after carbonization and activation, the phenolic resin activated carbon matrix with uniform particle size can be directly obtained, so that the preparation process of phenolic resin microspheres with uniform particle size is simplified, and the practicality of the preparation device is effectively improved.

[0054] It can be explained that, in the device for preparing the phenolic resin activated carbon matrix provided in this embodiment, the radial dimension of the discharge hole 332 is in the range of 0.1-1 mm, and the distance between adjacent discharge holes 332 is in the range of 1-4 mm.

[0055] It can be explained that in order to stably control the flow rate of the water-soluble phase, a control device should be added. Figure 1 and Figure 2 As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a control valve 48. In this case, the control valve 48 is arranged between the first outlet 111 and the second connection end 312.

[0056] It can be explained that in order to detect the flow rate of the water-soluble phase in real time, a detection device should be added. Figure 1 and Figure 2 As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a metering device 49. In this case, the metering device 49 is arranged between the control valve 48 and the second connecting end 312.

[0057] It can be explained that after obtaining phenolic resin microspheres with uniform particle size, the liquid phase will be mixed with the phenolic resin microspheres. Therefore, a separation member should be added to separate the phenolic resin microspheres and the liquid phase. Figure 1 As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a solid-liquid separation component 42. At this time, the inlet of the solid-liquid separation component 42 is connected to the outlet of the solidification component 41.

[0058] Furthermore, in order to improve the utilization rate of the liquid phase, the separated liquid phase can be re-transported to the forming column 2. Figure 1 As shown, in the preparation device of the phenolic resin activated carbon matrix provided in this embodiment, the molding column 2 is also provided with a second inlet 212, and the second inlet 212 is spaced apart from the first inlet 211; the solid-liquid separator 42 is also provided with a second outlet 421 and a third outlet 422, the second outlet 421 is arranged in the middle and lower part of the solid-liquid separator 42, and the third outlet 422 is arranged below the second outlet 421 along the height direction, and the third outlet 422 is connected to the second inlet 212. It should be noted that at this time, the second outlet 421 is used to output the phenolic resin microspheres after solid-liquid separation, and transport this part of the phenolic resin microspheres to an externally placed tubular furnace for carbonization and activation treatment; the third outlet 422 is used to output the liquid phase after solid-liquid separation, and transport this part of the liquid phase through the second inlet 212 to the inside of the molding column 2 for reuse.

[0059] Furthermore, in order to improve the efficiency of transporting the liquid phase after solid-liquid separation to the inside of the forming column 2, Figure 1 As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a pump body 43. At this time, the inlet of the pump body 43 is connected to the third outlet 422, and the outlet of the pump body 43 is connected to the second inlet 212.

[0060] Furthermore, since a portion of the liquid phase is lost during the polymerization process, and the liquid phase includes the oil phase and the dispersed phase, Figure 1 As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment needs to be further provided with a dispersed phase storage element 44 and an oil phase storage element 45, and the outlet of the dispersed phase storage element 44 is connected to the second inlet 212; the outlet of the oil phase storage element 45 is connected to the second inlet 212. At this time, as one of the implementation modes, the dispersed phase storage element 44 and the oil phase storage element 45 are both provided between the second inlet 212 and the third outlet 422.

[0061] It can be explained that, in order to improve the quality of the phenolic resin, a stirring structure should be added at the curing member 41. Figure 1As shown, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a stirring assembly. In this case, the stirring assembly is provided with a stirring driver 46 and a stirring rod 47. The stirring driver 46 is arranged above the curing member 41. The stirring rod 47 has a stirring end and a connecting end connected to each other. The stirring end is placed in the curing member 41. The connecting end of the stirring rod 47 passes through the entrance of the curing member 41 and is connected to the driving end of the stirring driver 46.

[0062] Since the phenolic resin microspheres need to be carbonized and activated when forming a phenolic resin activated carbon matrix, the preparation device of the phenolic resin activated carbon matrix provided in this embodiment should also include a tubular furnace, and the feed port of the tubular furnace is connected to the second outlet 421.

[0063] The present embodiment provides a device for preparing a phenolic resin activated carbon matrix. The water-soluble phase in the water-soluble phase storage element 1 enters the second connection end 312 of the actuator 31 and flows to the third connection end 313. It vibrates regularly under the drive of the vibrator 32 to form water-soluble phase microspheres with uniform particle size. The microspheres enter the molding column 2. At this time, the water-soluble phase microspheres move from top to bottom and undergo polymerization reaction during the falling process. After reaching a certain hardness, they enter the curing element 41 for further polymerization reaction to form phenolic resin microspheres with uniform particle size. They then enter the tubular furnace for carbonization and activation treatment to form a phenolic resin activated carbon matrix with uniform particle size.

[0064] Example 2

[0065] This embodiment provides a method for preparing a phenolic resin activated carbon substrate, which is applied to the preparation device for the phenolic resin activated carbon substrate provided in Example 1. The preparation method comprises:

[0066] S1: Preparation: The water-soluble phase in the water-soluble phase storage element 1 enters the second connection end 312, and the water-soluble phase is regularly vibrated under the drive of the vibrator 32, and is formed into microspheres of uniform size under the action of the liquid distributor 33 and enters the first inlet 211;

[0067] S2: Initial solidification: The microspheres are stably present in the oil phase in the molding column 2 due to the surface tension of the dispersed phase and the oil phase, and a polymerization reaction occurs during the movement from top to bottom in the molding column 2;

[0068] S3: re-solidification: the microspheres with increased hardness flow out from the outlet of the forming column 2 and enter the interior of the solidifying member 41 for further polymerization reaction, and finally obtain phenolic resin microspheres with uniform particle size;

[0070] S5: Activation: Stop the nitrogen flow and switch to water vapor flow, activate for 10 min, then stop the water vapor flow and switch to nitrogen flow, cool naturally to room temperature, and obtain a phenolic resin activated carbon matrix with uniform particle size.
