Description

Technical Field

[0001] The present invention relates to the technical field of carbon powder, and in particular to an inerting treatment device for preventing biochar from spontaneous combustion. Background Art

[0002] Carbon powder is a high-risk product, prone to spontaneous combustion during storage, transportation, and use. Addressing this issue remains a thorny issue within the carbon industry. Currently, the industry primarily utilizes sealed packaging, physically isolating the carbon powder from air to prevent spontaneous combustion. However, during actual storage and transportation, the sealed bags inevitably break, allowing the carbon powder to heat up upon contact with air, leading to spontaneous combustion and potentially serious safety incidents.

[0003] Currently, the charcoal industry has no effective solution to the problem of spontaneous combustion of charcoal dust caused by damaged sealing bags, with the only option being to thicken the bags. However, thickening the bags increases packaging costs and does not fundamentally solve the problem. Therefore, we have developed an inerting device to prevent biochar spontaneous combustion. Summary of the Invention

Put the dry carbon powder into the T-shaped feeding drum through the feeding port, drive the rotating rod to rotate through the motor, and the rotating rod drives the spiral blade to rotate. The dry carbon powder enters the rotary drum through the spiral blade, and in this process, the atomizing water spray pipe can spray water into the carbon powder while feeding. The carbon powder is kept evenly moistened by the rotation and stirring of the spiral blade and the rotary drum, thereby realizing "adding water to stir the dry carbon powder". At the same time, start the heating component and the refrigeration component, the heating component heats the hot water jacket, and the hot water jacket is filled with hot water of ℃~℃, so that the hot water jacket The wet carbon powder near the inlet of the rotary drum is preheated to achieve "preheating", and the oxidant (gaseous) is sprayed into the rotary drum. The refrigeration component cools the cooling water jacket, and the cooling water jacket cools the wet carbon powder near the outlet of the rotary drum to room temperature. The cooled inactivated carbon powder is discharged from the carbon outlet at the bottom of the settling chamber, thereby achieving "cooling down". The volatile organic matter adsorbed in the carbon powder undergoes a low-temperature oxidation reaction with the oxidant, thereby achieving "low-temperature oxidation". The treated carbon powder in the rotary drum enters the settling tank through the discharge pipe, and the induced draft fan is started. The induced draft fan draws out and discharges water vapor and exhaust gas, thereby achieving "induced draft discharge". Finally, the spiral discharge cylinder can be started to draw the carbon powder out of the rotary drum for packaging and storage.

[0006] According to the above technical solution, a trapezoidal column is fixed to the end of the rotating rod away from the spiral blade, and the trapezoidal column is located inside the rotating drum. A number of stirring plates are evenly fixed on the circumference of the outer wall of the trapezoidal column. The stirring plates are in contact with the inner wall of the rotating drum. The inner wall of the rotating drum is arranged in an inclined shape, and the inclination of the rotating drum is parallel to the inclined surface of the trapezoidal column. The rotating rod drives the trapezoidal column to rotate, and the trapezoidal column drives the stirring plate to rotate, so that the stirring plate stirs the wet carbon powder near the inlet of the rotating drum. At the same time, the trapezoidal column limits the speed of the wet carbon powder flowing to the outlet of the rotating drum during the preheating process.

When the convex ball of the L-shaped convex ball rod no longer pushes the semi-circular ball, the Z-shaped rod is reset under the action of the corresponding spring force, and the Z-shaped rod drives the baffle plate to swing in the direction of the trapezoidal column, and the baffle plate is blocked at the baffle plate again.

[0008] According to the above technical solution, the shielding device also includes an elastic telescopic column, the fixed end of the elastic telescopic column is fixed to the inner wall of the cavity of the trapezoidal column away from the T-shaped feeding tube, the telescopic end of the elastic telescopic column is fixed with a fixed disk, and a plurality of elastic telescopic rods are evenly fixed on the circumference of the outer wall of the fixed disk, and a sliding rod is fixed on the side of the elastic telescopic rod away from the fixed disk, and the sliding rod horizontally passes through the trapezoidal column, and a sliding groove for accommodating the sliding rod is provided on the inner wall of the cavity of the trapezoidal column, and a plurality of trapezoidal shovel plates are evenly and equidistantly fixed on both sides of the side of the sliding rod away from the trapezoidal column, the vertical support plate of the Z-shaped rod is in contact with the outer wall of the fixed disk, and the side of the trapezoidal shovel plate close to the T-shaped feeding tube is an inclined surface. When the Z-shaped rod is reset, the Z-shaped rod no longer pushes the fixed plate, and under the elastic force of the elastic telescopic column, the telescopic end of the elastic telescopic column pushes the fixed plate to reset and move, and the fixed plate drives the slide bar to reset and move through the elastic telescopic rod. At the same time, when the trapezoidal shovel plate moves away from the trapezoidal column, the inclined surface of the trapezoidal shovel plate will scoop up the carbon powder, and when the trapezoidal shovel plate moves toward the trapezoidal column, the vertical surface of the trapezoidal shovel plate will push the carbon powder to flow toward the trapezoidal column.

[0010] The present invention provides an inerting treatment device for preventing spontaneous combustion of biochar. It has the following beneficial effects:

[0011] (1) The present invention adopts a process flow of adding water for stirring, preheating, low-temperature oxidation, induced air discharge, and cooling. This process can remove the active substances contained in the carbon powder, making the carbon powder inactive and thus in a stable state. The carbon powder treated by this process is exposed to the air and the natural temperature rise is generally less than 20°C, which fundamentally solves the technical problem of spontaneous combustion of carbon powder during storage, transportation and use; at the same time, the rotating rod and the trapezoidal column cooperate to drive the stirring plate to stir the wet carbon powder near the entrance of the rotary drum, so that the carbon powder is stirred in the return drum. Uniform movement occurs in the rotating drum. This stirring effect helps to transfer the heat provided by the hot water jacket to the wet carbon powder more evenly, thereby avoiding the problem of wet carbon powder staying motionless in a local area and causing uneven preheating. At the same time, the trapezoidal column limits the speed at which the wet carbon powder flows to the outlet of the rotary drum during the preheating process. By limiting the speed at which the wet carbon powder flows to the outlet of the rotary drum, the carbon powder stays in the inlet of the rotary drum longer, which allows the hot water jacket to exchange heat with the carbon powder for a longer time, thereby ensuring that the carbon powder can fully absorb heat.

[0012] (2) The present invention drives the shielding plate to intermittently form a shield at the trapezoidal column through the cooperation of the shielding plate, trapezoidal column, Z-shaped rod, semi-circular ball, and L-shaped convex ball rod. The shielding plate can reduce heat waste by blocking the transfer of heat to the outlet area of ​​the rotary drum, thereby ensuring that the heat energy of the hot water jacket is concentrated on the inlet area of ​​the rotary drum.

[0013] (3) The present invention drives the trapezoidal shovel plate to shovel back and forth on the surface of the stirring plate by cooperating with the Z-shaped rod, the trapezoidal column, the fixed disk, and the elastic telescopic column. The wet carbon powder is easily adhered to the surface of the stirring plate due to the presence of water, resulting in a decrease in the stirring effect of the stirring plate. The trapezoidal shovel plate can effectively scrape off the carbon powder adhering to the surface by shoveling back and forth on the surface of the stirring plate, ensuring that the surface of the stirring plate remains clean and avoiding the accumulation of carbon powder, thereby ensuring the continuity and efficiency of the stirring process. At the same time, when the trapezoidal shovel plate moves in the direction away from the trapezoidal column, the inclined surface of the trapezoidal shovel plate will scoop up the carbon powder. When the trapezoidal shovel plate moves in the direction of the trapezoidal column, the vertical surface of the trapezoidal shovel plate will push the carbon powder toward the trapezoidal column. The coordinated action of the inclined surface and the vertical surface of the trapezoidal shovel plate can effectively push the carbon powder and make it flow, which helps to prevent the carbon powder from agglomerating or being retained in the rotary drum due to moisture.

[0014] (4) The present invention uses a rotating rod, a slide plate, a push block, and a resistance rod to drive the top block to move the carbon powder in the T-shaped feeding barrel, so that the water sprayed by the atomizing water spray pipe can penetrate the surface of the carbon powder more evenly. This uniform water distribution can avoid excessive or insufficient water in certain areas. BRIEF DESCRIPTION OF THE DRAWINGS

A sedimentation tank 115 is fixedly installed on the top of the bottom plate 1 through a bracket, and an induced draft fan 114 is fixed on the top of the sedimentation tank 115. A spiral discharge cylinder 116 is fixed to the bottom of the sedimentation tank 115. A round cover 112 is fixedly installed on the side of the sedimentation tank 115 close to the rotary drum 19 through a bracket. The rotary drum 19 is rotatably installed between the T-shaped feeding drum 14 and the round cover 112. A discharge pipe 113 is fixed between the round cover 112 and the top of the sedimentation tank 115. A heating component 118 and a refrigeration component 117 are fixed in the middle of the top of the bottom plate 1. A hot water jacket 18 is fixed to the top of the heating component 118 through a pipe, and a hot water jacket 18 is fixed to the top of the refrigeration component 117 through a pipe. A cooling water jacket 111 is fixed, and the hot water jacket 18 and the cooling water jacket 111 are respectively sleeved on both sides of the rotary drum 19. The dry carbon powder enters the rotary drum 19 through the spiral blade 142, and in this process, the atomizing water spray pipe 16 can spray water into the carbon powder while feeding. The carbon powder is kept uniformly moist by the rotating stirring of the spiral blade 142 and the rotary drum 19, thereby realizing "adding water to stir the dry carbon powder". At the same time, the heating component 118 and the refrigeration component 117 are started, and the heating component 118 heats the hot water jacket 18. Hot water at 50℃~80℃ is passed through the hot water jacket 18, so that the hot water jacket 18 preheats the wet carbon powder near the inlet of the rotary drum 19, thereby realizing "preheating and heating", and the oxidant (gaseous) is sprayed into the rotary drum. In the drum 19, the refrigeration component 117 cools the cooling water jacket 111, and the cooling water jacket 111 cools the wet carbon powder near the outlet of the rotary drum 19 to room temperature. The cooled inactivated carbon powder is discharged from the carbon outlet at the bottom of the settling chamber, thereby realizing "cooling down".

The treated carbon powder in the rotary drum 19 enters the settling tank 115 through the discharge pipe 113, and the induced draft fan 114 is started. The induced draft fan 114 draws out and discharges water vapor and exhaust gas, thereby realizing "induced draft discharge". By adopting the process flow of adding water and stirring, preheating and heating, low-temperature oxidation, induced draft discharge, and cooling down, this process can remove the active substances contained in the carbon powder.The carbon powder loses its activity and is in a stable state. After being treated by this process, the carbon powder is exposed to the air and its natural temperature rise is generally less than 20°C, which fundamentally solves the technical problem of spontaneous combustion of carbon powder during storage, transportation and use.

[0024] A trapezoidal column 119 is fixed to one end of the rotating rod 141 away from the spiral blade 142, and the trapezoidal column 119 is located inside the rotating drum 19. A plurality of stirring plates 120 are evenly fixed on the circumference of the outer wall of the trapezoidal column 119. The stirring plates 120 are in contact with the inner wall of the rotating drum 19. The inner wall of the rotating drum 19 is arranged in an inclined shape, and the inclination of the rotating drum 19 is parallel to the inclined surface of the trapezoidal column 119. Through the arrangement of the above structure, the stirring plates 120 stir the wet carbon powder near the inlet of the rotating drum 19, so that the carbon powder is evenly distributed in the rotating drum 19. Movement, this stirring effect helps to transfer the heat provided by the hot water jacket 18 to the wet carbon powder more evenly, thereby avoiding the wet carbon powder staying motionless in a local area and causing uneven preheating. At the same time, the trapezoidal column 119 limits the speed at which the wet carbon powder flows to the outlet of the rotary drum 19 during the preheating process. By limiting the speed at which the wet carbon powder flows to the outlet of the rotary drum 19, the carbon powder stays in the inlet of the rotary drum 19 for a longer time, which allows the hot water jacket 18 to exchange heat with the carbon powder for a longer time, thereby ensuring that the carbon powder can fully absorb heat.

[0025] A shielding device 2 is provided at the trapezoidal column 119, and the shielding device 2 includes a flowering slot disk 21 and an L-shaped convex ball rod 25. The flowering slot disk 21 is fixed to the side of the trapezoidal column 119 away from the T-shaped feeding barrel 14. The outer wall of the flowering slot disk 21 is provided with a plurality of grooves. The inner wall of the groove of the flowering slot disk 21 is hinged with a shielding plate 22. The interior of the trapezoidal column 119 is provided with a cavity. The inner circumference of the cavity of the trapezoidal column 119 is uniformly and laterally penetrated and slidably connected with a Z-shaped rod 23, and a spring is provided between the Z-shaped rod 23 and the trapezoidal column 119. A semicircular ball 24 is fixed to the side of the Z-shaped rod 23 close to the T-shaped feeding barrel 14. The Z-shaped rod 2 The side away from the T-shaped feeding cylinder 14 is slidably connected to the outer wall of the shielding plate 22. The L-shaped convex ball rod 25 is fixed at an eccentric position on the side of the T-shaped feeding cylinder 14 close to the rotary cylinder 19. A convex ball is fixed to the end of the L-shaped convex ball rod 25 away from the T-shaped feeding cylinder 14. The convex ball of the L-shaped convex ball rod 25 is located on the movement trajectory of the semicircular ball 24. With the above-mentioned structure, the shielding plate 22 intermittently forms a shield at the trapezoidal column 119. By blocking the transfer of heat to the outlet area of ​​the rotary cylinder 19, the shielding plate 22 can reduce heat waste, thereby ensuring that the heat energy of the hot water jacket 18 is concentrated on the inlet area of ​​the rotary cylinder 19.

[0026] The shielding device 2 also includes an elastic telescopic column 26, the fixed end of the elastic telescopic column 26 is fixed to the inner wall of the cavity of the trapezoidal column 119 away from the T-shaped feeding tube 14, the telescopic end of the elastic telescopic column 26 is fixed to a fixed plate 27, and a plurality of elastic telescopic rods 28 are evenly fixed on the outer wall of the fixed plate 27. A sliding bar 29 is fixed on the side of the elastic telescopic rod 28 away from the fixed plate 27, and the sliding bar 29 horizontally passes through the trapezoidal column 119, and a sliding groove for accommodating the sliding bar 29 is opened on the inner wall of the cavity of the trapezoidal column 119. A plurality of trapezoidal shovel plates 210 are evenly and equidistantly fixed on both sides of the side of the sliding bar 29 away from the trapezoidal column 119, the vertical support plate of the Z-shaped rod 23 contacts the outer wall of the fixed plate 27, and the trapezoidal shovel plate 210 is arranged on an inclined surface close to the T-shaped feeding tube 14, and the trapezoidal shovel plate 210 contacts the outer wall of the sliding bar 29. Through the arrangement of the above structure, the sliding bar 29 drives the trapezoidal shovel plate 2 The shovel blade 210 is moved back and forth on the surface of the stirring plate 120. Due to the presence of moisture, the wet carbon powder is easily adhered to the surface of the stirring plate 120, resulting in a decrease in the stirring effect of the stirring plate 120. The trapezoidal shovel blade 210 can effectively scrape off the carbon powder adhering to the surface by shoveling back and forth on the surface of the stirring plate 120, ensuring that the surface of the stirring plate 120 remains clean and avoids the accumulation of carbon powder, thereby ensuring the continuity and efficiency of the stirring process. At the same time, when the trapezoidal shovel blade 210 moves in the direction away from the trapezoidal column 119, the inclined surface of the trapezoidal shovel blade 210 will scoop up the carbon powder. When the trapezoidal shovel blade 210 moves in the direction of the trapezoidal column 119, the vertical surface of the trapezoidal shovel blade 210 will push the carbon powder toward the trapezoidal column 119. The coordinated action of the inclined surface and the vertical surface of the trapezoidal shovel blade 210 can effectively push the carbon powder and make it flow, which helps to prevent the carbon powder from agglomerating or retaining in the rotary drum 19 due to moisture.

[0027] During use, the atomizing water spray pipe 16 is connected to an external water source, the oxidant pipe 17 is connected to an external air source, the driving motor 13 is started, the driving motor 13 drives the belt ring 110 to rotate through the belt, the belt ring 110 drives the rotary drum 19 to rotate, and the dry carbon powder is put into the T-shaped feeding drum 14 through the feeding port of the T-shaped feeding drum 14, the motor drives the rotating rod 141 to rotate, the rotating rod 141 drives the spiral blade 142 to rotate, and the dry carbon powder enters the rotary drum 19 through the spiral blade 142, and in this process, the atomizing water spray pipe 16 can spray water into the carbon powder while feeding, and the carbon powder is kept uniformly moistened by the rotation and stirring of the spiral blade 142 and the rotary drum 19, thereby realizing "adding water to stir the dry carbon powder", and at the same time, the heating component 118 and the refrigeration component 117 are started, the heating component 118 heats the hot water jacket 18, and the hot water jacket 18 is passed through 50℃~80℃ ℃ hot water, so that the hot water jacket 18 preheats the wet carbon powder near the inlet of the rotary drum 19, thereby achieving "preheating and heating", and the oxidant (gaseous) is sprayed into the rotary drum 19. The refrigeration component 117 cools the cooling water jacket 111, and the cooling water jacket 111 cools the wet carbon powder near the outlet of the rotary drum 19 to room temperature. The cooled inactivated carbon powder is discharged from the carbon outlet at the bottom of the settling chamber, thereby achieving "cooling down". The volatile organic matter adsorbed in the carbon powder undergoes a low-temperature oxidation reaction with the oxidant, thereby achieving "low-temperature oxidation". The treated carbon powder in the rotary drum 19 enters the settling tank 115 through the discharge pipe 113, and the induced draft fan 114 is started. The induced draft fan 114 draws out and discharges water vapor and exhaust gas, thereby achieving "induced draft discharge". Finally, the spiral discharge cylinder 116 can be started to draw the carbon powder out of the rotary drum 19 for packaging and storage.

[0028] It should be noted that water is added to the dry charcoal powder, and the dry charcoal powder is stirred in a rotary kiln to keep it uniformly moist. The main purposes of adding 2% to 5% water are: a humid environment is conducive to the low-temperature oxidation reaction of volatile organic compounds; the heat absorption of water vapor can ensure that the ambient temperature is below 100°C, preventing the charcoal powder from igniting; preheating the temperature: in the rotary kiln, the charcoal powder is heated by circulating hot water externally to the wet charcoal powder to 50°C-80°C; low-temperature oxidation: oxygen or air is introduced into the rotary kiln as an oxidant (the amount of air added is controlled at 0.5-1 standard cubic meters per kilogram of charcoal powder, and oxygen is converted according to the oxygen content of air). The rotation of the rotary kiln ensures that the wet charcoal powder is fully in contact with the oxidant, and the volatile organic compounds adsorbed in the charcoal powder undergo a low-temperature oxidation reaction with the gaseous oxidant, depleting the active substances in the charcoal powder and rendering it inactive.

[0029] When the rotating rod 141 rotates, the rotating rod 141 drives the trapezoidal column 119 to rotate, and the trapezoidal column 119 drives the stirring plate 120 to rotate, so that the stirring plate 120 stirs the wet carbon powder near the inlet of the rotary drum 19, so that the carbon powder moves evenly in the rotary drum 19. This stirring effect helps to transfer the heat provided by the hot water jacket 18 to the wet carbon powder more evenly, thereby avoiding the wet carbon powder staying motionless in a local area and causing uneven preheating. At the same time, the trapezoidal column 119 limits the speed of the wet carbon powder flowing to the outlet of the rotary drum 19 during the preheating process. By limiting the speed of the wet carbon powder flowing to the outlet of the rotary drum 19, the carbon powder stays in the inlet of the rotary drum 19 for a longer time, which allows the hot water jacket 18 to exchange heat with the carbon powder for a longer time, thereby ensuring that the carbon powder can fully absorb heat. It should be noted that the rotating rod 141 here rotates in the opposite direction to that of the rotary drum 19.

[0030] At the same time, the shielding plate 22 will form a shield at the trapezoidal column 119. When the trapezoidal column 119 rotates, the semi-circular ball 24 will be driven to rotate through the Z-shaped rod 23. When the semi-circular ball 24 rotates to the convex ball position of the L-shaped convex ball rod 25, the convex ball of the L-shaped convex ball rod 25 pushes the semi-circular ball 24 to drive the Z-shaped rod 23 to move in the direction of the trapezoidal column 119. The Z-shaped rod 23 pushes the shielding plate 22 to swing away from the trapezoidal column 119. The shielding plate 22 no longer forms a shield at the trapezoidal column 119. The carbon powder can flow from the carbon powder to the outlet of the rotary drum 19. When the L When the convex ball of the Z-shaped convex ball rod 25 no longer pushes the semi-circular ball 24, the Z-shaped rod 23 is reset under the action of the corresponding spring force, and the Z-shaped rod 23 drives the baffle plate 22 to swing in the direction of the trapezoidal column 119. The baffle plate 22 is now blocked again at the baffle plate 22, and this cycle is repeated, so that the baffle plate 22 intermittently blocks the trapezoidal column 119. The baffle plate 22 can reduce heat waste by blocking the transfer of heat to the outlet area of ​​the rotary drum 19, thereby ensuring that the heat energy of the hot water jacket 18 is concentrated on the inlet area of ​​the rotary drum 19.

[0031] When the Z-shaped rod 23 is reset, the Z-shaped rod 23 no longer pushes the fixed plate 27. Under the elastic force of the elastic telescopic column 26, the telescopic end of the elastic telescopic column 26 pushes the fixed plate 27 to reset and move. The fixed plate 27 drives the slide bar 29 to reset and move through the elastic telescopic rod 28, and so on. As a result, the slide bar 29 drives the trapezoidal shovel plate 210 to shovel back and forth on the surface of the stirring plate 120. The wet carbon powder is easily adhered to the surface of the stirring plate 120 due to the presence of moisture, resulting in the stirring plate 120 being 0's stirring effect is reduced, and the trapezoidal shovel plate 210 can effectively scrape off the carbon powder adhering to the surface by shoveling back and forth on the surface of the stirring plate 120, ensuring that the surface of the stirring plate 120 remains clean and avoids the accumulation of carbon powder, thereby ensuring the continuity and efficiency of the stirring process. At the same time, when the trapezoidal shovel plate 210 moves in the direction away from the trapezoidal column 119, the inclined surface of the trapezoidal shovel plate 210 will scoop up the carbon powder, and when the trapezoidal shovel plate 210 moves in the direction of the trapezoidal column 119, the vertical surface of the trapezoidal shovel plate 210 will push the carbon powder toward the trapezoidal column 119. The coordinated action of the inclined surface and the vertical surface of the trapezoidal shovel plate 210 can effectively push the carbon powder and make it flow, which helps to avoid the carbon powder from agglomerating or being retained in the rotary drum 19 due to wetting.

[0032] See also Figure 1 - Figure 6 On the basis of the above embodiment, in another embodiment of the present invention, a square groove is opened inside the rotating rod 141, and a slide plate 145 is slidably installed inside the square groove of the rotating rod 141, and a spring is provided between the slide plate 145 and the inner wall of the square groove of the rotating rod 141, and a plurality of top blocks 146 are fixed on the top of the slide plate 145 at even intervals, and the plurality of top blocks 146 vertically penetrate the inner wall of the square groove of the rotating rod 141, and a push block 144 is fixed to the bottom of the end of the slide plate 145 away from the T-shaped feeding barrel 14, and the push block 144 vertically penetrates the inner wall of the square groove of the rotating rod 141, and the L-shaped convex ball A resistance rod 143 is fixed to the bottom of the rod 25, and the end of the push block 144 away from the slide plate 145 is semicircular. The end of the resistance rod 143 away from the L-shaped convex ball rod 25 is semicircular. The semicircular shape of the resistance rod 143 is located on the semicircular movement trajectory of the push block 144. Through the setting of the above structure, the slide plate 145 drives the top block 146 to move the carbon powder in the T-shaped feeding barrel 14, so that the water sprayed by the atomizing water spray pipe 16 can penetrate into the surface of the carbon powder more evenly. This uniform moisture distribution can avoid excessive or insufficient moisture in certain areas.

[0033] During use, when the rotating rod 141 rotates, the push block 144 will be driven to rotate through the slide plate 145. When the semicircular shape of the push block 144 rotates to the semicircular position of the resistance rod 143, the semicircular shape of the resistance rod 143 pushes the semicircular shape of the push block 144 to drive the slide plate 145 to slide along the square groove of the rotating rod 141. When the semicircular shape of the resistance rod 143 no longer pushes the semicircular shape of the push block 144, the slide plate 145 is reset under the action of the corresponding spring force, and so on. As a result, the slide plate 145 drives the top block 146 to move the carbon powder in the T-shaped feeding barrel 14, so that the water sprayed by the atomizing water spray pipe 16 can penetrate the surface of the carbon powder more evenly. This uniform moisture distribution can avoid excessive or insufficient moisture in certain areas.
