Description

Technical Field

[0001] This invention relates to the field of activated carbon modification, and in particular to a method and apparatus for producing modified activated carbon for VOC waste gas treatment. Background Technology

[0002] Activated carbon can adsorb various air pollutants, including VOCs, thanks to its well-developed pores on its surface. Activated carbon can be regenerated during operation when VOCs are not being treated. Specifically, this is achieved by controlling the temperature during the regeneration phase of the activated carbon particles and / or by purging the activated carbon particles with other purified air sources.

[0003] Currently, Chinese patent application number CN202010413545.0 discloses a highly efficient modified activated carbon capable of adsorbing multiple VOC gases and its preparation method, comprising 30-70% modified wood charcoal and 30-70% modified coal charcoal. The modified wood charcoal is prepared by using wood powder as the raw material, polyvinyl alcohol, surfactant, crosslinking agent, modifier and water to form an adhesive. The modified coal charcoal uses coal columnar carbon as the raw material and surfactant, modifier, regulator and water as catalysts, which can simultaneously adsorb different types of harmful gases.

[0004] However, the technical solutions of the aforementioned patents can only achieve the purpose of preparing modified activated carbon, and cannot simultaneously achieve the purpose of regenerating modified activated carbon. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a modified activated carbon production device for VOC waste gas treatment.

[0006] The technical solution to achieve the purpose of this invention is as follows:

[0007] In a first aspect, the present invention provides a modified activated carbon production apparatus for VOC waste gas treatment, comprising:

[0008] The modified main container includes an activated carbon particle loading section and a modified source output section, wherein the modified main container is located in the modified source output section;

[0009] A heat supply device for providing heat to an activated carbon modification reaction, including a columnar heat output section whose column length extends vertically;

[0010] A cooling unit that reduces the temperature required for activated carbon modification reactions to a range;

[0011] The loading unit for loading activated carbon has multiple modification source channels and a block section. The input direction of the modified source channels intersects the radial direction of the columnar heat output section and the heat-conducting pipe. The block section divides the internal space of the modified main container into an activated carbon particle loading section side and a modification source output section side. Each modified source channel penetrates the block section, so that the internal space of the modified main container is connected between the activated carbon particle loading section side and the modification source output section side. At least a portion of the modified source channels are separated from the heating device and the cooling unit.

[0012] The activated carbon modification source unit includes four activated carbon modification source devices that output modification sources to activated carbon particles through the modification source output section of the modification main container. The activated carbon particles output by the four activated carbon modification source devices are of different types, and the activated carbon particles output by three of the four activated carbon modification source devices have a sequential order.

[0013] The heating device, the cooling unit, and the loading unit are all located inside the modified main container.

[0014] In some embodiments, the cooling unit includes multiple spaced, vertically arranged and longitudinally parallel heat-conducting pipes internally for configuring temperature-regulating fluid. The vertical distance between the sidewalls of adjacent heat-conducting pipes is 2-4 cm and larger than the particle size of the activated carbon particles. The vertical distance between the side of the heat-conducting pipe closest to the columnar heat output section and the outer peripheral surface of the columnar heat output section is 9-12 cm. All the heat-conducting pipes are located on the outer periphery of the columnar heat output section.

[0015] In some embodiments, the modified source channel includes:

[0016] The first modified source channel has an inclined portion that is tilted at an angle relative to the horizontal plane, and the inclined portion is a straight channel; the first modified source channel has a loading side opening that opens upward on the side of the activated carbon particle loading portion, and the upper part of the loading side opening is not blocked by other parts; when the block is viewed from above, 90% of the opening area of ​​the loading side opening of the first modified source channel overlaps with the inner wall of the first modified source channel, and the position of the activated carbon particles falling on the inner wall of the first modified source channel remains unchanged;

[0017] The second modified source channel has a vertical portion that is perpendicular to the horizontal plane, and each vertical portion is a straight channel; the inner diameter of the second modified source channel is smaller than the particle size of the activated carbon particles;

[0018] Both the first modification source channel and the second modification source channel penetrate the block, making the space between the activated carbon particle loading section and the modification source output section in the modified main container connected. Furthermore, the first modification source channel and the second modification source channel are independent of each other.

[0019] In some embodiments, it further includes: a door movably disposed on the side wall of the activated carbon particle loading section of the modified main container, such that the door switches between an open state and a closed state;

[0020] When the door is in the closed state, the door is coplanar with the inner wall surface of the activated carbon particle loading section of the modified main container.

[0021] The door and the side wall of the activated carbon particle loading section of the modified main container together form an opening channel for conveying activated carbon particles to the activated carbon particle loading section.

[0022] When the door is in the open state, the opening channel is open, and activated carbon particles can freely enter and exit the activated carbon particle loading part through the opening channel; when the door is in the closed state, the opening channel is closed, and activated carbon particles cannot enter or exit the activated carbon particle loading part due to the opening channel.

[0023] In some embodiments, the columnar heat output section includes: a column body extending vertically and a plurality of electric heating elements, all of which are distributed along the column body and circumferentially disposed on the outer side wall of the column body. The outer side of the column body is circumferentially disposed with a heat-permeable, tubular circumferential portion, which leaves gaps between the circumferential portion and all of the electric heating elements, and the circumferential portion surrounds the column body and all of the electric heating elements in its inner space.

[0024] In some embodiments, the cooling unit includes: an output pipe, an input pipe, and an intermediate pipe connecting the output pipe and the input pipe. The intermediate pipe includes four rows of intermediate pipe groups. Each row of intermediate pipe groups includes multiple intermediate pipes arranged vertically and in a parallel straight line, with internal spacing for configuring temperature-regulating fluid. The lengths of the output pipe and the input pipe extend horizontally. The output pipe is located above the input pipe, and the intermediate pipes serve as heat-conducting pipes.

[0025] The four intermediate tube groups are arranged horizontally parallel to each other and spaced apart. The heating device is located in the middle of the four intermediate tube groups when viewed from above. Two intermediate tube groups are located to the left of the cooling unit, while the other two intermediate tube groups are located to the right of the cooling unit.

[0026] In some embodiments, the inclined portion faces the open channel side;

[0027] With the opening channel closed, non-reactive gases that do not react with activated carbon particles are injected from the first modification source channel and the second modification source channel. The opening channel is then opened while the injection of non-reactive gases is maintained. As a result, the activated carbon particles in the activated carbon particle loading section are squeezed out to the opening channel side by the non-reactive gases.

[0028] In some embodiments, three of the four activated carbon modification source devices sequentially output activated carbon modification source one, activated carbon modification source three, and activated carbon modification source four to the modification source output section of the modification main container. Activated carbon modification source one uses oxygen, activated carbon modification source three uses nitrogen, and activated carbon modification source four uses hydrogen.

[0029] In some embodiments, it also includes:

[0030] A modified secondary container for arranging the modified main container therein;

[0031] A second channel is provided on the modified sub-body container, with a first end extending into the modified main body container and a second end located outside the modified sub-body container;

[0032] A third channel is provided on the modified sub-body container, with the first end of the third channel extending into the modified sub-body container and the second end located outside the modified sub-body container;

[0033] An activated carbon modification source conveying line connects the activated carbon modification source unit to the second end of the third channel;

[0034] Activated carbon modification source discharge equipment;

[0035] The activated carbon modification source discharge line connects the activated carbon modification source discharge device to the second end of the second channel;

[0036] A first temperature monitoring unit for monitoring the temperature of the area between the modified secondary container and the modified main container is disposed on the modified secondary container;

[0037] A second temperature monitoring unit for monitoring the temperature inside the modified host container is provided on the second channel;

[0038] A safety backup line connects the activated carbon modification source conveying line to the activated carbon modification source discharge device, wherein the connection point between the safety backup line and the activated carbon modification source conveying line is the backup line connection point.

[0039] A first line opening and closing control unit is installed on the line segment of the activated carbon modification source conveying line located between the backup line connection point and the second end of the third channel; and

[0040] Four second-line switching control units control the output switching status of each activated carbon modification source device.

[0041] Secondly, the present invention provides a method for producing modified activated carbon for VOC waste gas treatment. Based on the aforementioned apparatus for producing modified activated carbon for VOC waste gas treatment, the method includes the following steps:

[0042] Step S1: Activated carbon particles are loaded into the activated carbon particle loading section of the modified main container. During this process, the heating device provides heat to the activated carbon modification reaction in the activated carbon particle loading section of the modified main container. The cooling unit adjusts the temperature in the activated carbon particle loading section of the modified main container according to the temperature required for the activated carbon modification reaction by the flow of temperature-regulating fluid in the heat-conducting pipe.

[0043] Step S2: The activated carbon modification source unit outputs modification source to the activated carbon particles through the modification source output section of the modification body container. The activated carbon particles output by the four activated carbon modification source devices are all of different types. The activated carbon particles output by three of the four activated carbon modification source devices have a sequential order, thus obtaining activated carbon modified particles.

[0044] Step S3: If a portion of the activated carbon modified particles obtained in step S2 do not meet the quality requirements, the activated carbon modified particles that do not meet the quality requirements are reloaded into the activated carbon particle loading section of the modification main container. During this process, heat is provided to the activated carbon modified particles that do not meet the quality requirements through the heating device and / or purified gas is supplied to the activated carbon modified particles that do not meet the quality requirements through the activated carbon modification source unit until regenerated activated carbon particles are obtained.

[0045] Step S4: The regenerated activated carbon particles obtained in step S3 are then processed again through steps S1 and S2 until activated carbon modified particles that meet the quality requirements are obtained.

[0046] The significant advantages of this invention compared to existing technologies are:

[0047] This invention constructs an activated carbon particle loading section within a modified main container to serve as the space for the activated carbon particle modification reaction. A heating device provides heat for the activated carbon modification reaction, improving its efficiency. Furthermore, since the heating device is also located within the activated carbon particle loading section of the modified main container, and its heat output component is a columnar heat output section extending vertically, heat is concentrated and evenly distributed within the activated carbon particle loading section, improving heat utilization. If the temperature within the activated carbon particle loading section of the modified main container is too high, a cooling unit is incorporated to control the required temperature for the activated carbon modification reaction within a suitable range. Specifically, the cooling unit uses a heat-conducting pipe with a temperature-regulating fluid inside to exchange heat with the activated carbon particle loading section of the modified main container, achieving cooling. It should be noted that, to accommodate the structure of the columnar heat output section and achieve rapid cooling... For the purpose of temperature control, all heat-conducting pipes are spaced apart and arranged vertically and in a parallel straight line. The vertical distance between the side of the heat-conducting pipe closest to the columnar heat output section and the outer periphery of the columnar heat output section is 9-12 cm. All the heat-conducting pipes are located on the outer periphery of the columnar heat output section. Furthermore, the vertical pipe spacing between the sidewalls of adjacent heat-conducting pipes is 2-4 cm and is greater than the particle size of the activated carbon particles. This vertical pipe spacing facilitates the installation of each heat-conducting pipe and does not affect the flow of activated carbon particles in the activated carbon particle loading section of the modified main container. The loading unit in this invention, as a component that carries activated carbon particles, also has the function of conveying the modification source into the activated carbon particle loading section of the modified main container. The modification source channel, especially its actual modification source output direction, does not collide with the columnar heat output section and the heat-conducting pipes, which can reduce the mutual influence between the modification source and the columnar heat output section and the heat-conducting pipes. This invention can not only prepare modified activated carbon particles by gas source modification, but also purify modified activated carbon particles that do not meet the quality requirements by using a heat device and / or the purified gas source output from the activated carbon modification source unit.

[0059] like Figure 1a and Figure 1b As shown, the modified activated carbon production device for VOC waste gas treatment includes a modified main container 10, a heating device 11, a cooling unit 12, a loading unit 15, and an activated carbon modification source unit. The heating device 11, the cooling unit 12, and the loading unit 15 are all installed inside the modified main container 10.

[0060] The modified main container 10 has a vent at its lower end, and a second channel 16 is disposed on the modified secondary container 18. The first end of the second channel 16 extends into the modified main container 10, while the second end is located outside the modified secondary container 18. The modified main container 10 can be disposed within the modified secondary container 18 through the second channel 16. The modified secondary container can be cylindrical, and the second channel 16 extends to the outside of the modified secondary container 18. During operation, at least a portion of the second temperature monitoring unit 17 and the first temperature monitoring unit 19 are disposed within the modified main container 10 and the modified secondary container 18, respectively, to monitor the temperature inside the modified main container 10 and the temperature of the space inside the modified secondary container 18, respectively. Specifically, the first temperature monitoring unit 19 is used to monitor the temperature of the area between the modified secondary container 18 and the modified main container 10, and is disposed on the modified secondary container 18; the second temperature monitoring unit 17 is used to monitor the temperature inside the modified main container 10, and is disposed on the second channel 16. The third channel 20 is disposed on the modified sub-body container 18. The first end of the third channel 20 extends into the modified sub-body container 18 while the second end is located outside the modified sub-body container 18. The activated carbon modification source conveying line 22 connects the activated carbon modification source unit to the second end of the third channel 20.

[0061] The activated carbon modification source unit includes four activated carbon modification source devices that output modification sources to activated carbon particles through the modification source output section of the modification body container. The activated carbon particles output by the four activated carbon modification source devices are of different types, and the activated carbon particles output by three of the four activated carbon modification source devices have a sequential order.

[0062] Specifically, activated carbon modification source output devices 24, 25, 26, and 27 are connected to the activated carbon modification source conveying line 22 via line opening and closing control units 31, 32, 33, and 34. Line opening and closing control units 31, 32, 33, and 34 serve as a second line opening and closing control unit, supplying gas to the modification main container 10. Other components, such as a material output amplitude adjustment unit 29, a pressure regulating valve 28, a pressure sensor 30, and a line opening and closing control unit 35, are also installed in the activated carbon modification source conveying line 22 to monitor and control the flow rate and pressure of the gas delivered to the modification main container 10. Specifically, the line opening and closing control unit 35 serves as the first line opening and closing control unit, which is located on the line segment of the activated carbon modification source conveying line between the backup line connection point and the second end of the third channel 20. The activated carbon modification source output device is used to store and output the activated carbon modification source, wherein the activated carbon modification source is a gas. The second channel 16 of the modification body container 10 is connected to the activated carbon modification source discharge line 36, which includes a unidirectional flow section 37 and is connected to the activated carbon modification source discharge device 38. A safety backup line 40 with a shut-off valve 42 is also connected to the activated carbon modification source supply conveying line 22 and the activated carbon modification source discharge device 38, which discharges to the atmosphere through the discharge channel 44.

[0063] In operation, gas flow 45 enters the modified auxiliary container 18 through the third channel 20. The gas can be heated, for example, when passing through the space between the modified main container 10 and the modified auxiliary container 18. It then enters the modified main container 10 through the first channel 14, where activated carbon particles 100 are placed. Gas flow 45 passes through the modified main container 10. The second channel 16 may also be equipped with a filter or screen to further help prevent particles 46 from escaping from the modified main container 10. Gas flow 45 exits the modified main container 10 through the second channel 16 and flows through the activated carbon modification source discharge line 36 to the activated carbon modification source discharge device 38, thereby being discharged into the atmosphere through the discharge channel 44.

[0064] As described above, the modified host container 10 contains activated carbon particles 100. The contact between the activated carbon particles and the activated carbon modification source promotes the modification treatment of the activated carbon particles, which will be described in more detail below. Activated carbon has high surface channel porosity, providing a high surface area.

[0065] In operation, a gas mixture, including oxygen from the activated carbon modification source output device 24, is first conveyed through the feed activated carbon modification source conveying line 22. The flow rate and gas pressure are controlled by the material output amplitude regulating unit 29 and the pressure regulating valve 28. Prior to this, the activated carbon particles may have undergone an activation process by being exposed to heated oxygen to oxidize and remove pyrolysis reaction products from the carbon channel volume. The oxygen exposure operation disclosed herein is for the purpose of preparing the activated carbon for nitriding, an additional oxidation step applied to the carbon that has already been activated (including oxidative activation) to form activated carbon.

[0066] The activated carbon modification source in the activated carbon modification source output device 24 includes oxygen and an inert gas (e.g., nitrogen). The activated carbon modification source is heated, and in one embodiment, the temperature in contact with the activated carbon particles under reaction conditions is in the range of 160°C–480°C. The activated carbon particles can be in contact with the activated carbon modification source in the modification host container 10 for a period of time, for example, 3–7 hours.

[0067] After the activated carbon particles are treated with a heated activated carbon modification source one, they can be selectively treated in an oxidizing gas by contacting an inert gas (e.g., nitrogen) in a modification host container 10. The inert gas, as activated carbon modification source two, can be supplied by activated carbon modification source two output device 25. After the activated carbon particles 100 are treated with activated carbon modification source one by heating and any inert gas, the oxidized activated carbon particles are treated in the modification host container 10 with activated carbon modification source three from activated carbon modification source three output device 26. Activated carbon modification source three is used to functionalize the surface of the oxidized activated carbon; activated carbon modification source three includes nitrogen, which is also heated; in one embodiment, activated carbon modification source three contacts the oxidized activated carbon particles under reaction conditions, with a temperature range of 450°C at the lower end, 750°C at the higher end, and one or more inert gases for the remainder. The oxidized activated carbon particles can be in contact with the activated carbon modification source 3 in the modification host container 10 for a period of time, such as 2-8 hours. This can be preceded by a 1-hour heating treatment at 350°C when the reaction temperature is above 500°C. The target nitrogen content can enhance the adsorption capacity of the activated carbon particles, including enhanced adsorption capacity under humid conditions.

[0068] After treatment with heated activated carbon modification source three, the nitrided activated carbon particles are treated by contacting an inert gas (e.g., nitrogen) supplied by activated carbon modification source two output device 25 in the modification host container 10. The nitrided activated carbon particles are then treated in the modification host container 10 with activated carbon modification source four from activated carbon modification source four output device 27. Activated carbon modification source four may include hydrogen, used to promote an increase in the hydrophobicity of the nitrided activated carbon surface compared to before treatment with activated carbon modification source four. Activated carbon modification source four may be pure hydrogen or may include inert gases other than nitrogen. The nitrided activated carbon particles may be contacted with activated carbon modification source four in the modification host container 10 for a period of time, for example, 2–8 hours.

[0069] After treating the nitrided activated carbon particles with heated activated carbon modification source four, they can be further treated by contacting them with inert gases such as helium, nitrogen, or argon in the modification host container 10. These inert gases can be supplied by the activated carbon modification source two output device 25. The treatment time with activated carbon modification source four is approximately 1.5 hours. The temperature range after treatment with activated carbon modification source four is 45°C to 90°C. In one embodiment, the enhanced activated carbon powder can be separated into different particle size ranges to suit different applications. Activated carbon may experience a reduction in adsorption capacity under high humidity conditions. In one embodiment, the above-described treatment schemes using activated carbon modification source one, activated carbon modification source three, and activated carbon modification source four can provide the technical effect of reducing the adsorption capacity of activated carbon under the influence of humidity.

[0070] like Figure 2 As shown, in one embodiment, the modified main container 10 includes a heating device 11, a cooling unit 12, and a loading unit 15.

[0071] like Figure 2 As shown, the modified main container 10 is generally box-shaped, having a top wall 40, side walls 41-44, and a bottom wall 45, and an internal space 50 constructed by these walls 40-45. Furthermore, the modified main container 10 is equipped with an activated carbon particle loading section 51 and a modification source output section 52. Moreover, as... Figure 3 As shown, the sidewall portions 41 to 44 are composed of a first sidewall portion 141 to 144 in which the activated carbon particle loading portion 51 is disposed and a second sidewall portion 161 to 164 in which the modified source output portion 52 is disposed.

[0072] The heating device 11 is a device that provides heat to the activated carbon particles 100. Specifically, the heating device 11 is used to regulate the temperature in the area where the activated carbon particles 100 are located. Figure 2 As shown, the heating device 11 extends in a columnar shape in the vertical direction and has a circular cross-section.

[0073] like Figure 4 and Figure 5 As shown, the heating device 11 includes a columnar heat output section 22, which comprises a columnar main body 20 extending vertically and circumferential portions 21 disposed around the columnar main body 20. Electric heating elements 23 are distributed on the sidewalls of the columnar main body 20. Specifically, all the electric heating elements 23 are distributed along the columnar length of the columnar main body 20 and circumferentially mounted on the outer sidewalls of the columnar main body 20.

[0074] The circumferential portion 21 is a heat-permeable protective component that allows heat to be substantially evenly distributed and extracted to the outside (the side of activated carbon particles 100) through heat emitted from the column body portion 20. For example... Figure 5 As shown, the circumferential portion 21 is tubular, and a column body portion 20 is inserted inside it. A gap 25 is formed between the outer circumferential surface of the column body portion 20 and the inner circumferential surface of the circumferential portion 21. The gap 25 can be an empty space.

[0075] The cooling unit 12 is a device that can adjust the interior of the modified main container 10 to a predetermined temperature and maintain the interior of the modified main container 10 at a constant temperature. This cooling unit 12 is an air-cooled or water-cooled cooling device that suppresses the temperature rise associated with the reaction heat of the activated carbon particles 100 and the modification source.

[0076] like Figure 2 As shown, the cooling unit 12 is mainly composed of heat pipes. The cooling unit 12 has an output pipe 30, an input pipe 31, and an intermediate pipe 32 connecting the output pipe 30 and the input pipe 31.

[0077] The inlet pipe 31 is the part that allows the temperature-regulating fluid to flow from the outside into the intermediate pipe 32, and the outlet pipe 30 is the part that allows the temperature-regulating fluid that has undergone heat exchange in the intermediate pipe 32 to flow out to the outside.

[0078] like Figure 4 As shown, the intermediate pipe 32 has one or more rows of intermediate pipe groups 33, each intermediate pipe group 33 including intermediate pipes 35 arranged in a straight line with parallel spacing.

[0079] like Figure 2 As shown, the intermediate pipe assembly 33 connects the output pipe 30 and the input pipe 31, and is a tubular assembly extending in the vertical direction, through which temperature-controlled fluid can pass. Both the output pipe 30 and the input pipe 32 extend horizontally, with the output pipe 30 located above the input pipe 31.

[0080] like Figure 4 As shown, the shortest distance D2 between the sides of the two intermediate tubes 35 that are closest in the longitudinal direction y is preferably 2 cm.

[0081] If these ranges are determined, the flow of activated carbon particles 100 is unlikely to be obstructed by the intermediate tube 35, and the activated carbon particles 100 can be thoroughly mixed. In addition, maintaining the activated carbon particles 100 at a certain temperature can also reduce temperature unevenness of the activated carbon particles 100.

[0082] like Figure 4 As shown, the intermediate pipe 32 has two or more rows of intermediate pipe groups 33 in the horizontal x direction, and the intermediate pipes 35 form the apex of the positive plane loading. Therefore, the temperature influence area of ​​the activated carbon particles 100 can be reduced.

[0083] The shortest distance D3 between the sides of the middle pipes 35 of the two closest intermediate pipe groups 33 in the horizontal x-axis is equal to the vertical distance D2 between the sides of the two closest intermediate pipes 35 in the vertical y-axis. That is, the shortest distance D3 is 2-4 cm, preferably 2 cm.

[0084] like Figure 2 As shown, the loading unit 15 is a plate-shaped body arranged horizontally inside the modified main container 10, dividing the surrounding space 50 of the modified main container 10 into the activated carbon particle loading section 51 side and the modified source output section 52 side.

[0085] like Figure 6a As shown, the loading unit 15 has a block section 55 and multiple modification source channels 56.

[0086] like Figure 2 As shown, the block portion 55 is a component that forms the bottom of the activated carbon particle loading portion 51 between the middle portions of the side wall portions 41 to 44 of the modified main container 10 in the vertical direction.

[0087] like Figure 6b As shown, the modified source channel 56 is a channel connecting the activated carbon particle loading section 51 and the modified source output section 52, and is a through channel through the block section 55.

[0088] The opening rate of the modified source channel 56 is preferably 0.4% to 4%. Within this range, the modified source can be stably supplied while maintaining the rigidity of the block portion 55.

[0089] like Figure 6a , Figure 6b As shown in Figure 7, the modified source channel 56 is composed of a first modified source channel 150 and a second modified source channel 151.

[0090] The first modification source channel 150 is a channel that includes at least an italic portion 152 having a horizontal component, and has both a horizontal component and a vertical component overall.

[0091] In this embodiment, the first modification source channel 150 is an inclined channel consisting only of the italic portion 152 and inclined at a predetermined angle relative to the horizontal plane. For example... Figure 6a and Figure 6b As shown, the first modification source channel 150 is an inclined channel that extends in a straight line and penetrates the block portion 55 in an inclined direction.

[0092] like Figure 6a and Figure 6b As shown, the loading-side opening 145 serves as the first modification source channel 150, opening upward on the side of the activated carbon particle loading section 51, and the loading-side opening 145 is not blocked by other parts above it.

[0093] like Figure 7b As shown, a large portion of the loading-side opening 145 of the first modified source channel 150 overlaps with the inner wall surface constituting the first modified source channel 150 when viewed from above the block portion 55. That is, the center of the loading-side opening 145 is offset from the center of the supply-side opening 146 when viewed from above.

[0094] Preferably, more than 90% of the loading-side opening 145 overlaps with the inner wall surface constituting the first modification source channel 150. In this embodiment, the loading-side opening 145 completely overlaps with the inner wall surface constituting the first modification source channel 150, and the supply-side opening 146, which serves as the opening channel for the modification source output section 52, is not visible from the activated carbon particle loading section 51 side. Therefore, it is possible to further prevent the activated carbon particles 100 from falling out of the first modification source channel 150.

[0095] Figure 6b The first modified source channel 150 shown has a block portion 55 with an inclination angle θ1 relative to the surface (horizontal plane) of the modified source output portion 52. θ1 is the minimum angle at which the activated carbon particles 100 are held on the inclined surface and are close to sliding down. Within this range, the activated carbon particles 100 can be prevented from falling along the inclined surface of the first modified source channel 150.

[0096] Furthermore, the tilt angle θ1 is preferably less than 45 degrees. Within this range, compared to the past, the falling of activated carbon particles 100 from the first modification source channel 150 to the modification source output section 52 can be suppressed, and the activated carbon particles 100 can be mixed efficiently. Therefore, the activated carbon particles 100 can react with the modification source gas evenly, and the target modified activated carbon particles can be formed.

[0097] The first modified source channel 150 preferably has a circular opening shape at the loading side opening 145, and the opening shape at the supply side opening 146 is also preferably circular. By forming this opening channel shape, gas can easily diffuse uniformly within the activated carbon particle loading section 51. In this embodiment, the first modified source channel 150 has the same channel shape throughout the entire depth direction.

[0098] The inner diameter (circumscribed diameter, diameter of the smallest enclosing circle) of the first modified source channel 150 is preferably at least 6 times the median diameter of the activated carbon particles 100. Furthermore, the inner diameter (circumscribed diameter, diameter of the smallest enclosing circle) of the first modified source channel 150 is preferably 9 times or less the median diameter of the activated carbon particles 100. Within these ranges, a greater number of first modified source channels 150 per unit area can be provided while simultaneously preventing activated carbon particles 100 from falling into the modified source output section 52 or blocking the first modified source channel 150.

[0099] In this embodiment, the inner diameter of the first modification source channel 150 is less than nine times the median diameter of the activated carbon particles 100. Therefore, compared to the conventional method, it is possible to suppress the falling of activated carbon particles 100 from the first modification source channel 150 towards the modification source output section 52, and to efficiently mix the activated carbon particles 100. Thus, a superior modification configuration can be formed, enabling the activated carbon particles 100 to react uniformly with the modification source gas.

[0100] like Figure 6b As shown, the second modification source channel 151 is a vertical channel that extends in a straight line along the up-down direction (vertical direction), and preferably the channel shape is circular.

[0101] The inner diameter (outer diameter, minimum enclosing circle diameter) of the second modified source channel 151 is preferably smaller than the inner diameter (outer diameter, minimum enclosing circle diameter) of the first modified source channel 150. Within this range, the activated carbon particles 100 can be prevented from falling from the second modified source channel 151 to the modified source output section 52.

[0102] The activated carbon granule loading section 51 is a component capable of containing activated carbon granules 100, and is a downward-opening box. For example... Figure 3 As shown, the activated carbon particle loading section 51 includes a top wall section 40 and loading side wall sections 141 to 144 that rise from the loading unit 15.

[0103] As shown in Figure 1, a loading side wall portion 141 has an opening channel 170 that can be opened and closed through a door portion 171.

[0104] The channel 170 is used to load activated carbon granules 100 into a receiving component (not shown), which is a channel connecting the inside and outside of the activated carbon granule loading section 51.

[0105] A door 171 is movably (e.g., hinged) disposed on the side wall of the activated carbon particle loading section of the modified main container. The door 171 is a component that opens and closes the opening channel 170 by switching between a closed state and an open state via a power source (not shown). That is, in the closed state, the door 171 is coplanar with the inner wall surface of the loading side wall 141, closing the opening channel 170; in the open state, it moves away from the loading side wall 141, opening the opening channel 170. The door 171 and the side wall of the activated carbon particle loading section of the modified main container together constitute the opening channel 170 for conveying activated carbon particles to the activated carbon particle loading section. Specifically, when the door 171 is in the open state, the opening channel 170 is open, allowing activated carbon particles to freely enter and exit the activated carbon particle loading section; when the door 171 is in the closed state, the opening channel 170 is closed, preventing activated carbon particles from entering or exiting the activated carbon particle loading section due to the opening channel 170.

[0106] As shown in Figure 1 and Figure 3 As shown, the modified source output section 52 is mainly composed of supply sidewall sections 161-164 and bottom sidewall section 45.

[0107] As shown in Figure 1 and Figure 3 As shown, the loading unit 15 divides the interior of the modified main container 10 vertically, forming the boundary between the activated carbon particle loading section 51 and the modified source output section 52. The axis of the modified source channel 56 of the loading unit 15 is perpendicular to the length direction of the columnar heat output section 22 of the heat device 11 or the intermediate tube 35 of the cooling unit 12.

[0108] The block section divides the internal space of the modified main container into an activated carbon particle loading section and a modified source output section; each modified source channel penetrates the block section, so that the internal space of the modified main container is connected between the activated carbon particle loading section and the modified source output section, and at least a portion of the modified source channels are separated from the heating device and the cooling unit.

[0109] As shown in Figure 1 and Figure 3 As shown, the heating device 11 and cooling unit 12 are partially or entirely disposed within the activated carbon granule loading section 51, located above the loading unit 15, and extending vertically. The columnar heat output section 22 of the heating device 11 is vertically extended, and the circumferential section 21 surrounds the outer side of the column body section 20. The output pipe 30 and input pipe 31 of the cooling unit 12 are horizontally extended, and the intermediate pipe 35 connecting the output pipe 30 and input pipe 31 is vertically extended.

[0110] like Figure 4As shown, the intermediate pipe 32 includes four rows of intermediate pipe groups 33, which are arranged horizontally parallel to each other and spaced apart. Each row of intermediate pipe groups 33 includes multiple intermediate pipes 35 arranged vertically and longitudinally parallel, with internal spacers for configuring temperature-regulating fluids. The intermediate pipes 35 serve as heat-conducting components. The columnar heat output section 22, when viewed from above, is located between the four intermediate pipe groups 33 and surrounded by the intermediate pipes 32. Two intermediate pipe groups 33 are located on the left side of the cooling unit 12, while the other two intermediate pipe groups 33 are located on the right side of the cooling unit 12.

[0111] Figure 5 The vertical distance D1 between the outer peripheral surface of the columnar heat output section 22 and the side surface of the intermediate tube 35 closest to the columnar heat output section 22 is 9-12 cm, preferably 10 cm. Within this range, the activated carbon particles 100 can be thoroughly mixed, and the outer peripheral surface of the intermediate tube 35 absorbs at least a portion of the heat, thereby preventing the temperature of the activated carbon particle modification reaction from rising. That is, the temperature near the columnar heat output section 22, which serves as the reaction field, can be adjusted to an appropriate temperature, and a suitable reaction temperature can be maintained under a state of thorough mixing. Therefore, compared with the past, the reaction efficiency can be improved, and modified activated carbon particles of a certain quality or higher can be mass-produced.

[0112] Specifically, the cooling unit 12 includes multiple spaced heat-conducting pipes arranged vertically and in a longitudinally parallel straight line for configuring temperature-regulating fluid. The vertical distance between the sidewalls of adjacent heat-conducting pipes is 2-4 cm and is greater than the particle size of the activated carbon particles. The vertical distance between the side of the heat-conducting pipe closest to the columnar heat output section and the outer peripheral surface of the columnar heat output section is 9-12 cm. All heat-conducting pipes are located on the outer periphery of the columnar heat output section.

[0113] like Figure 8 As shown, the first modification source channels 150 are uniformly and densely packed when viewed from above, with equal intervals between each first modification source channel 150. That is, the first modification source channels 150 are equally arranged to form the vertices of the planar loading shape.

[0114] Figure 8 The distance D11 between one first modified source channel 150a and its adjacent first modified source channel 150b is equal to the distance D12 between one first modified source channel 150a and its adjacent other first modified source channels 150c. Furthermore, this distance D11 is also equal to the distance D13 between the first modified source channel 150b and its adjacent other first modified source channels 150c.

[0115] Thus, in the loading unit 15 of this embodiment, the first modification source channels 150 are uniformly arranged. Therefore, more first modification source channels 150 can be formed per unit area on the loading unit 15, and the activated carbon particles 100 in the modification body container 10 can flow uniformly. Therefore, the generation of non-flowing portions can be suppressed while effectively causing the reaction, thereby improving the quality of the modified activated carbon compared to the past.

[0116] The first modified source channel 150 is concentrated on the central side to form the first modified source channel group.

[0117] The second modified source channel 151 is configured to surround at least a portion or all of the first modified source channel group. The second modified source channel 151 is disposed along the edge of the block portion 55 near a loading-side sidewall portion that serves as the inner wall of the activated carbon particle loading portion 51. The distance between adjacent second modified source channels 151 is equal. That is, the second modified source channel 151 is disposed along the loading-side sidewall portion closer to it than the first modified source channel 150.

[0118] For example, as shown in Figure 1 and Figure 3 As shown, when all the first modified source channels 150 are inclined in the same direction and the open channel on the side of the activated carbon particle loading portion 51 is facing a loading side wall portion 141, the second modified source channel 151 is at least disposed near the loading side wall portion 143 on the opposite side of the loading side wall portion 141.

[0119] In other words, the second modified source channel 151 is at least located in the portion where the open channel density (open channel area per unit area) of the first modified source channel 150 monomer is small when viewed from the side of the activated carbon particle loading section 51 looking down at the loading unit 15. In this embodiment, the second modified source channel 151, as... Figure 3 As shown, the sidewall portions 141 to 144 are installed along all four directions.

[0120] Open channel 170 as needed, as shown in Figure 1 and Figure 3 The device is positioned slightly higher than the loading unit 15 and may have a step with the loading unit 15. In this case, the step forms a barrier, preventing the cleaning fluid from leaking to the outside when cleaning the modified body container 10, thus facilitating the cleaning of the modified body container 10.

[0121] The italicized portion 152 of the first modified source channel 150, as shown in Figure 1 and Figure 3 The opening is shown to the side facing the opening channel 170 and to the loading side wall portion 141 where the opening channel 170 is provided.

[0122] First, as shown in FIG1, activated carbon particles 100 are loaded into activated carbon particle loading section 51 in a state of direct contact with the upper surface of loading unit 15, and activated carbon particles 100 are placed on loading unit 15.

[0123] While driving and controlling the cooling unit 12 to keep the temperature inside the modified main container 10 within a certain range, the activated carbon particles 100 are heated by the columnar heat output section 22 of the heat device 11.

[0124] In this embodiment, as shown in Figure 1 and Figure 3 As shown, the gas injection direction from the modified source channel 56 intersects the longitudinal direction of the columnar heat output section 22 of the heat device 11 and the intermediate tube 35 of the cooling unit 12. Therefore, the modified source gas is unlikely to collide with the side of the columnar heat output section 22 or the intermediate tube 35 at a right angle, and is unlikely to be blocked by that side.

[0125] like Figure 5 As shown, there is a gap 25 between the column body 20 and the circumferential part 21. The heat emitted from the columnar heat output part 22 diffuses through the gap 25 and diffuses into the activated carbon particles 100 in the activated carbon particle loading part 51.

[0126] A temperature-regulating fluid, such as a low-temperature liquid or gas, is used to regulate the temperature of the activated carbon particles 100 through the intermediate tube 35. Therefore, the activated carbon particles 100 are not exposed to the temperature-regulating liquid or gas, and heat exchange is possible.

[0127] like Figure 4 As shown, when viewed along the length of the columnar heat output section 22 of the heat device 11, the columnar heat output section 22 is positioned away from the side wall portions 41 to 44, which serve as the inner wall of the modified main container 10. Therefore, heat can be dissipated in multiple directions.

[0128] like Figure 4 As shown, the heating device 11 can dissipate heat in multiple directions, and the columnar heat output section 22 of the heating device 11 is arranged between the intermediate tube groups 33. Therefore, heat can be dissipated to each intermediate tube group 33 simultaneously, which helps to cause the activated carbon particles 100 to react over a wide area.

[0129] As shown in Figure 1 and Figure 3 As shown, all the first modified source channels 150 are inclined in the same direction, and the open channels on the side of the activated carbon particle loading section 51 are all oriented towards a loading side wall section 141. That is, the open channels on the side of the activated carbon particle loading section 51 are biased towards one direction (towards a loading side wall section 141), and the modified source gas is concentrated in one direction.

[0130] Therefore, when the supply channel 56 of the loading unit 15 is only composed of the first modified source channel 150, which is an inclined channel, the modified source is difficult to flow near the loading side wall portion 143 (hereinafter also referred to as the opposite side wall portion 143) which is opposite to one loading side wall portion 141. Therefore, there is a problem that the flowability of the activated carbon particles 100 near the opposite side wall portion 143 is reduced.

[0131] That is, the flow of the injected gas is biased in one direction, especially near the loading side wall 143 on the side opposite to the tilt direction, which may create a stagnant area. If a stagnant area is created, the activated carbon particles 100 in the stagnant area may have poor flow.

[0132] Therefore, as Figure 7a As shown, a second modification source channel 151 is provided at least near the opposite side wall portion 143. Compared to the loading side wall portion 141 side, flowability can be ensured even near the opposite side wall portion 143 where gas flowability is lower.

[0133] Furthermore, in this embodiment, the opening diameter of the second modified source channel 151 is smaller than the opening diameter of the first modified source channel 150, so the activated carbon particles 100 hardly fall off. Therefore, due to the presence of the second modified source channel 151 extending in the vertical direction, the activated carbon particles 100 are difficult to fall off from the second modified source channel 151.

[0134] Additionally, as shown in this embodiment, a second modification source channel 151 may also be provided near the loading side wall portions 141, 142, and 144, other than the opposing side wall portion 143.

[0135] As shown in Figure 1 and Figure 3 As shown, an opening channel 170 is provided, which can be opened and closed through the door 171, and the inclined portion 152 faces the opening channel 170 side. Therefore, for example, when the opening channel 170 is closed, a non-reactive gas that does not react with the activated carbon particles 100 is injected from the first modification source channel 150 and the second modification source channel 151, and the opening channel 170 is opened while maintaining the injection of the non-reactive gas. As a result, the activated carbon particles 100 in the activated carbon particle loading section 51 are squeezed out towards the opening channel 170 side by the non-reactive gas. Even between the first modification source channel 150 and the second modification source channel 151, that is, in the parts where the first modification source channel 150 and the second modification source channel 151 are not provided, the activated carbon particles 100 are squeezed out. Therefore, all or most of the activated carbon particles 100 in the activated carbon particle loading section 51 can be easily distributed to the receiving component (not shown), and maintenance such as cleaning of the activated carbon particle loading section 51 becomes easier.

[0136] This invention constructs an activated carbon particle loading section within a modified main container to serve as the space for the activated carbon particle modification reaction. A heating device provides heat for the activated carbon modification reaction, improving its efficiency. Furthermore, since the heating device is also located within the activated carbon particle loading section of the modified main container, and its heat output component is a columnar heat output section extending vertically, heat is concentrated and evenly distributed within the activated carbon particle loading section, improving heat utilization. If the temperature within the activated carbon particle loading section of the modified main container is too high, a cooling unit is incorporated to control the required temperature for the activated carbon modification reaction within a suitable range. Specifically, the cooling unit uses a heat-conducting pipe with a temperature-regulating fluid inside to exchange heat with the activated carbon particle loading section of the modified main container, achieving cooling. It should be noted that, to accommodate the structure of the columnar heat output section and achieve rapid cooling... For the purpose of temperature control, all heat-conducting pipes are spaced apart and arranged vertically and in a parallel straight line. The vertical distance between the side of the heat-conducting pipe closest to the columnar heat output section and the outer periphery of the columnar heat output section is 9-12 cm. All the heat-conducting pipes are located on the outer periphery of the columnar heat output section. Furthermore, the vertical pipe spacing between the sidewalls of adjacent heat-conducting pipes is 2-4 cm and is greater than the particle size of the activated carbon particles. This vertical pipe spacing facilitates the installation of each heat-conducting pipe and does not affect the flow of activated carbon particles in the activated carbon particle loading section of the modified main container. The loading unit in this invention, as a component that carries activated carbon particles, also has the function of conveying the modification source into the activated carbon particle loading section of the modified main container. The modification source channel, especially its actual modification source output direction, does not collide with the columnar heat output section and the heat-conducting pipes, which can reduce the mutual influence between the modification source and the columnar heat output section and the heat-conducting pipes. This invention can not only prepare modified activated carbon particles by gas source modification, but also purify modified activated carbon particles that do not meet the quality requirements by using a heat device and / or the purified gas source output from the activated carbon modification source unit.

[0137] The foregoing is merely intended to illustrate the principles of the invention. Furthermore, since many modifications and variations will readily occur to those skilled in the art, it is not intended to limit the invention to the exact structures and operations shown and described. While preferred embodiments have been described, details may be changed without departing from the essential concept of the invention. Therefore, the technical solutions involved in this invention include not only the technical solutions disclosed above, but also technical solutions constituted by equivalent substitutions of the technical features involved in the technical solutions of this invention. Matters not covered in this invention are common knowledge to those skilled in the art.
