Description

Technical Field

[0001] This invention relates to the field of activated carbon production, specifically to an environmentally friendly activated carbon production method. Background Technology

[0002] Activated carbon is a specially treated type of carbon with a well-developed microporous structure on its surface. It is this structure that gives activated carbon its excellent adsorption properties, enabling it to be used for dehumidification, deodorization, and water purification.

[0003] Activated carbon is similar to other types of carbon in terms of raw materials, generally bamboo, wood, and fruit shells. The first step in the production of activated carbon is to carbonize these raw materials, which means placing them in a carbonization container and heating them in the absence of air, using high temperature to carbonize them.

[0004] During the carbonization process, the raw materials release some polluting gases such as sulfur dioxide and carbon dioxide, which may contribute to the greenhouse effect. Therefore, these gases need to be treated, such as the environmentally friendly activated carbon production equipment disclosed in CN108584955A.

[0005] There are two ways to treat waste gas: one is to spray an alkaline solution, and the other is to directly pass the waste gas into the alkaline solution. In both of these methods, the time for the waste gas to mix with the alkaline solution is relatively limited, which cannot ensure sufficient reaction time and therefore cannot ensure that the harmful substances in the waste gas are completely removed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an environmentally friendly activated carbon production method. By circulating the mixed bubbles and alkaline solution between a circulation pipe and a reaction tank, the contact time between the waste gas and the alkaline solution is increased, allowing the waste gas and alkaline solution to react fully and ensuring that harmful substances in the waste gas are completely removed. This method can effectively solve the problems in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an environmentally friendly activated carbon production method, the specific steps of which are as follows:

[0008] S1: Open one end of the carbonization chamber and then put the powdered raw material into the carbonization chamber;

[0009] S2: Turn on the gas heating device to heat the carbonization chamber and its internal raw materials from the bottom. At the same time, turn on the arc heating plate to heat the raw materials inside the carbonization chamber synchronously. Use the motor to drive the first gear to rotate, which will turn the raw materials inside.

[0010] S3: The exhaust gas generated during the heating process is injected into the gas storage tank, and cold water is injected into the water storage tank at the same time. The cold water can absorb the heat of the exhaust gas and cool it down.

[0011] S4: The waste gas inside the gas storage tank is processed every 2 minutes. During processing, the waste gas inside the gas storage tank is introduced into the ventilation pipe. The waste gas entering the ventilation pipe is injected into the alkaline solution, where small bubbles are formed and react with the alkaline solution.

[0012] S5: Turn on the water pump. The water pump drives the solution to flow. The bubbles generated by the alkaline solution and waste gas are drawn into the circulation pipe from the bottom of the circulation pipe and then return to the reaction tank. They are then drawn into the circulation pipe again, and so on.

One end of the central tube extends to the outside of the carbonization chamber through a first outer tube. The central tube and the first outer tube are connected by a sealed bearing. The wiring is introduced into the hollow heating block through the central tube and the wiring channels in order to control the arc-shaped heating plate.

[0021] Furthermore, a heat recovery assembly is provided at one end of the first conveying pipe. The heat recovery assembly includes a water storage tank, an air storage tank is fixedly provided on the inner wall of the water storage tank, and a detachable sealing cap is installed at the top of the water storage tank. The sealing cap can seal the air storage tank.

[0022] One end of the first delivery pipe passes through the sealing cap and is connected to the inside of the gas storage cylinder.

[0032] Compared with existing technologies, the present invention provides an environmentally friendly activated carbon production method, which has the following beneficial effects:

[0033] 1. The exhaust gas is divided into small bubbles by a separator and thoroughly mixed with an alkaline solution. Then, the water pump is turned on, so that the mixed bubbles and alkaline solution circulate between the circulation pipe and the reaction tank, increasing the contact time between the exhaust gas and the alkaline solution, and maximizing the reaction between the exhaust gas and the alkaline solution to ensure that harmful substances in the exhaust gas are fully removed.

[0034] 2. A top cover and a hollow heating block are installed inside the carbonization chamber. Both are always vertically downward under their own gravity. The raw materials inside the carbonization chamber are distributed between the bottom of the hollow heating block and the bottom of the carbonization chamber. In this way, the hollow heating block restricts the distribution range of the raw materials inside the carbonization chamber and controls the thickness of the raw materials inside the carbonization chamber, so as to avoid the raw materials in the center not being fully heated due to excessive accumulation.

[0035] 3. While limiting the thickness of the raw material accumulation inside the carbonization chamber by the top cover and hollow heating blocks, the arc-shaped heating plate is powered on. The arc-shaped heating plate heats the raw material inside the carbonization chamber simultaneously through the hollow heating blocks. The gas heating device heats the raw material from below, and the hollow heating blocks heat the raw material from above, making the raw material heated more evenly inside the carbonization chamber.

[0046] To make the technical means, creative features, and achieved objectives and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0047] This invention provides an environmentally friendly activated carbon production method, the specific steps of which are as follows:

[0048] S1: Open one end of the carbonization chamber 1, and then put the powdered raw material into the carbonization chamber 1;

[0049] S2: Turn on the gas heating device 2 to heat the carbonization chamber 1 and the raw materials inside from the bottom. At the same time, turn on the arc heating plate 20 to heat the raw materials inside the carbonization chamber 1 synchronously. Use the motor 9 to drive the first gear 14 to rotate, which will turn the raw materials inside.

[0050] S3: The exhaust gas generated during the heating process is injected into the gas storage tank 602, and at the same time, cold water is injected into the water storage tank 601. The cold water can absorb the heat of the exhaust gas and cool it down.

[0051] S4: The waste gas inside the gas storage cylinder 602 is processed every 2 minutes. During processing, the waste gas inside the gas storage cylinder 602 is input into the ventilation pipe 702. The waste gas entering the ventilation pipe 702 is injected into the alkaline solution, where small bubbles are formed and react with the alkaline solution.

[0052] S5: Turn on the water pump 709. The water pump 709 drives the solution to flow. The bubbles generated by the alkaline solution and waste gas are drawn into the circulation pipe 706 from the bottom of the circulation pipe 706. Then they return to the reaction tank 701 and are drawn into the circulation pipe 706 again, and so on.

[0053] S6: When the pH value of the solution no longer changes significantly, the electromagnet 712 is energized to generate magnetic force, causing the bellows 707 to move above the liquid surface, opening the valve of the exhaust pipe, and discharging the treated waste gas from the waste gas treatment component 7.

[0054] like Figure 1-9 As shown, in order to realize the above-mentioned environmentally friendly activated carbon production method, the present invention provides an activated carbon production device for the environmentally friendly activated carbon production method. The activated carbon production device includes a carbonization chamber 1. Both ends of the carbonization chamber 1 are equipped with detachable end caps 11. A first outer tube 16 and a second outer tube 21 are respectively fixed on the two end caps 11. Vertical plates 3 are provided on both sides of the carbonization chamber 1. The first outer tube 16 and the second outer tube 21 pass through the two vertical plates 3 respectively and are movably connected to the vertical plates 3 through bearings.

[0055] The bottom of the carbonization chamber 1 is provided with a base 8, one of the upright plates 3 is installed on the top of the base 8 via a slide rail, and the other upright plate 3 is fixedly installed on the top of the base 8. The bottom of the carbonization chamber 1 is provided with a gas heating device 2 installed on the base 8.

[0056] Disconnect the end cap 11 on the side where the first outer tube 16 is located from the carbonization chamber 1. Then, drive the vertical plate 3 connected to the end cap 11 to move via the slide rail, thereby moving the end cap 11 to open one end of the carbonization chamber 1. Then, put the powdered raw material into the carbonization chamber 1. Then, slide the slide rail and use the end cap 11 to close the carbonization chamber 1 again. After the raw material is sealed inside the carbonization chamber 1, turn on the gas heating device 2. The nozzle of the gas heating device 2 sprays gas. After the gas is ignited, it heats the carbonization chamber 1 and the raw material inside from the bottom, and the raw material is gradually carbonized by heating.

[0057] During the heating and carbonization process, the raw materials are stirred, such as... Figure 1-4As shown in Figure 9, a second gear 15 is fixedly provided at the outer end of the first outer tube 16, and a first gear 14 that meshes with the second gear 15 is provided at the bottom of the second gear 15. The first gear 14 is movably connected to one of the vertical plates 3 through a rotating shaft. A motor 9 is installed on one of the display screens 13, and the output shaft of the motor 9 passes through one of the display screens 13 and is fixedly connected to the first gear 14.

[0058] Another upright plate 3 is equipped with a controller 12 and a display screen 13. The display screen 13, the gas heating device 2 and the motor 9 are all located at the output end of the controller 12. The display screen 13 can display relevant parameters such as gas pressure and pH value.

[0059] A sleeve 4 is fixedly provided on another upright plate 3. One end of the second outer tube 21 extends into the inside of the sleeve 4 and is movably connected to the inner wall of the sleeve 4 through a sealed bearing. A first delivery pipe 5 with a one-way valve is fixedly provided on the rear side of the sleeve 4.

[0060] While heating, the motor 9 is turned on, driving the first gear 14 to rotate. The first gear 14 drives the second gear 15 and the first outer tube 16 to rotate, causing the carbonization chamber 1 to rotate and turning the raw materials inside. During the heating process, the raw materials will generate waste gas, which is discharged to the outside through the second outer tube 21, the sleeve 4, and the first conveying pipe 5.

[0061] While heating the external parts, the raw materials are also heated from the inside, such as... Figure 3 , 4 As shown in Figure 9, the carbonization chamber 1 is provided with a hollow heating block 18 inside, and an arc-shaped heating plate 20 is installed on the inner wall of the hollow heating block 18. The arc-shaped heating plate 20 is located at the output end of the controller 12, and a detachable top cover 17 is installed on the top of the hollow heating block 18.

[0062] The carbonization chamber 1 is equipped with a central tube 10. The bottom end of the central tube 10 is provided with two wiring channels 19 that can penetrate the top cover 17. One end of the central tube 10 extends to the outside of the carbonization chamber 1 through the first outer tube 16. The central tube 10 and the first outer tube 16 are connected by a sealed bearing. The wiring is introduced into the hollow heating block 18 through the central tube 10 and the wiring channels 19 in order to control the arc heating plate 20.

[0063] While external heating is being applied, the arc-shaped heating plate 20 is energized. The arc-shaped heating plate 20, separated by the hollow heating block 18, simultaneously heats the raw materials inside the carbonization chamber 1, ensuring uniform heating of the raw materials within the carbonization chamber 1. The top cover 17 and the hollow heating block 18 inside the carbonization chamber 1 remain vertically downward under their own gravity. The raw materials inside the carbonization chamber 1 are distributed between the bottom of the hollow heating block 18 and the bottom of the carbonization chamber 1. This restricts the distribution range of the raw materials inside the carbonization chamber 1 through the hollow heating block 18, preventing the raw materials from piling up too thickly and causing the raw materials in the center to not be fully heated. Note that the amount of raw materials inside the carbonization chamber 1 should not be excessive.

[0064] During the exhaust process, it is also necessary to fully recover the heat from the exhaust gas, such as Figure 1 , 2 As shown in Figures 3, 8, and 9, a heat recovery assembly 6 is provided at one end of the first conveying pipe 5. The heat recovery assembly 6 includes a water storage cylinder 601, an air storage cylinder 602 is fixedly provided on the inner wall of the water storage cylinder 601, and a detachable sealing cap 603 is installed at the top of the water storage cylinder 601. The sealing cap 603 can seal the air storage cylinder 602.

[0065] One end of the first delivery pipe 5 passes through the sealing cover 603 and is connected to the inside of the air storage cylinder 602. A pressure sensor 604 is installed on the inner wall of the air storage cylinder 602. The pressure sensor 604 is located at the input end of the controller 12 and detects the air pressure inside the air storage cylinder 602 in real time.

[0066] The outer end of the gas storage cylinder 602 is fixedly provided with a second conveying pipe 605 with a valve. One end of the second conveying pipe 605 extends to the outside of the carbonization chamber 1 and is provided with a waste gas treatment component 7.

[0067] Two liquid guide pipes with valves are fixedly installed at the outer end of the water storage cylinder 601 to replace the water inside the water storage cylinder 601.

[0068] The exhaust gas discharged through the first conveying pipe 5 is injected into the gas storage cylinder 602 and accumulates there. At the same time, cold water is injected into the water storage cylinder 601. The cold water can absorb the heat of the exhaust gas and cool it down. The cold water can also absorb the heat of the exhaust gas, making full use of the heat and reducing energy consumption. The exhaust gas inside the gas storage cylinder 602 is processed every 2 minutes. During processing, the valve on the second conveying pipe 605 is opened, and the exhaust gas inside the gas storage cylinder 602 is input into the exhaust gas treatment component 7 through the second conveying pipe 605.

[0069] By reacting an alkaline solution with harmful gases such as carbon dioxide and sulfur dioxide in the exhaust gas, such as... Figure 5-9As shown, the exhaust gas treatment component 7 includes a reaction chamber 701, and a vent pipe 702 is provided inside the reaction chamber 701. The top end of the vent pipe 702 extends to the top of the reaction chamber 701, and one end of the second conveying pipe 605 is connected to the vent pipe 702.

[0070] The bottom end of the vent pipe 702 is threaded with a threaded sleeve 703. A dividing mesh 704 is fixed on the inner wall of the threaded sleeve 703. Two external pipes with valves are fixed on one side of the reaction chamber 701. The alkaline solution inside the reaction chamber 701 is replaced through the external pipes.

[0071] The waste gas entering the waste gas treatment component 7 enters the vent pipe 702. The reaction chamber 701 is filled with an alkaline solution, and the bottom end of the vent pipe 702 is inserted into the solution. Therefore, the waste gas entering the vent pipe 702 is injected into the alkaline solution. During the injection process, the waste gas is divided by the dividing screen 704, forming small bubbles in the solution and reacting with the alkaline solution, so that the waste gas and the alkaline solution are mixed evenly to facilitate a full reaction.

[0072] During the reaction, the mixing time between the waste gas and the alkaline solution should be extended as much as possible to ensure a complete reaction. Figure 5-9 As shown, a pH sensor 705 is fixedly installed at the bottom of the reaction chamber 701. The pH sensor 705 is located at the input end of the controller 12. An exhaust pipe with a valve is fixedly installed at the top of the reaction chamber 701 to finally discharge the treated waste gas.

[0073] The other side of the reaction chamber 701 is provided with a circulation pipe 706, and a water pump 709 is fixedly installed on the circulation pipe 706. The water pump 709 is located at the output end of the controller 12, and the bottom end of the circulation pipe 706 extends into the interior of the reaction chamber 701.

[0074] The top end of the circulation pipe 706 extends into the interior of the reaction chamber 701 and is fixedly provided with a corrugated pipe 707. The bottom end of the corrugated pipe 707 is fixedly provided with a connecting plate 714. A detachable inspection plate is installed on the rear side of the reaction chamber 701 to facilitate the inspection and maintenance of the internal parts of the reaction chamber 701.

[0075] The reaction chamber 701 is provided with a slide rod 708 inside, and end pieces 710 are fixedly provided at both ends of the slide rod 708. The end pieces 710 are fixedly provided on the inner wall of the reaction chamber 701.

[0076] One end of the connecting plate 714 is fixedly provided with a slide block 713 sleeved on the outer end of the slide rod 708. A spring 711 is fixedly provided at the top of the slide block 713, and an electromagnet 712 is fixedly provided on the top end piece 710. The top of the spring 711 is fixedly connected to the electromagnet 712. The electromagnet 712 is located at the output end of the controller 12.

[0077] During the waste gas injection process, water pump 709 is turned on, driving the solution to flow and drawing the solution into circulation pipe 706 from the bottom. Since the bottom of circulation pipe 706 is close to the bottom of vent pipe 702, bubbles generated by the waste gas at vent pipe 702 are also drawn into circulation pipe 706. The waste liquid and bubbles entering circulation pipe 706 flow along it and into bellows 707, then return to reaction tank 701, where they are drawn back into circulation pipe 706, repeating this cycle. As the reaction proceeds, the alkaline solution inside reaction tank 701 is consumed by the waste gas, causing the pH value of the solution to continuously change. When the pH value of the solution no longer... Once a noticeable change occurs, it indicates that the substances in the waste gas have reacted fully with the solution. At this point, the electromagnet 712 is energized, generating magnetic force that attracts the slide block 713, causing it to move upward and contract the bellows 707 upward until it reaches above the liquid surface. This stops the circulation of liquid for the bubbles. The valve of the exhaust pipe is then opened, allowing the treated waste gas to be discharged from the waste gas treatment component 7. In this way, the bubbles in the waste gas are mixed with the alkaline solution and circulate between the circulation pipe 706 and the reaction tank 701, increasing the contact time between the waste gas and the alkaline solution and maximizing the reaction time to ensure that the harmful substances in the waste gas are fully removed.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
