Description

Technical Field

[0001] The invention relates to the technical field of carbon molecular sieves, in particular to a drying device and a carbon molecular sieve preparation device. Background Art

[0002] With the full advancement of the "dual carbon" goals, my country's industrial structure and economic growth model are constantly upgrading. Under the background of the whole society's low-carbon transformation, combined with the energy-saving and environmental protection requirements of the factory area, it has become an inevitable trend to optimize the energy-saving of high-energy-consuming processes.

[0003] The drying process in the production of carbon molecular sieves is a major energy-consuming process. This process bakes and dehydrates the raw materials (such as phenolic foam) after the previous rough crushing, and then enters the next ball milling process. At present, the drying process of carbon molecular sieve production in the industry mainly relies on electric heating or natural gas heating. This method not only has high equipment investment costs, but also considerable operating costs.

[0004] In the carbonization process of carbon molecular sieve production, the carbonization furnace will generate a large amount of waste gas during the carbonization of the material. The main components of the waste gas include volatile organic matter, multi-carbon organic matter, carbon monoxide and hydrogen, etc. The waste gas of these mixed components is combustible and needs to be treated for environmental protection before being discharged. At present, the most efficient treatment method is to ignite and fully burn in the incinerator. The high-temperature flue gas generated in the combustion process is cooled in the preheating furnace and then enters the alkali spraying device, and finally discharged through the chimney.

[0005] However, the high-temperature flue gas generated by the incinerator is cooled and discharged through the waste heat furnace, which not only wastes a lot of heat sources, but also evaporates a lot of water resources. Therefore, in order to achieve the goal of energy saving and environmental protection, it is necessary to improve and optimize the existing carbon molecular sieve preparation method.

[0006] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the inventive concept and may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on this, it is necessary to provide a drying device and a carbon molecular sieve preparation device to address the above problems.

[0008] The present application provides a drying device, which comprises:

[0009] A drying furnace, the drying furnace comprising a furnace core and a furnace chamber, the furnace chamber encloses a receiving cavity, the furnace core is arranged in the receiving cavity and is used for drying materials;

[0010] an air intake assembly, one end of which is in communication with the accommodating chamber, and the other end of which is in communication with the incinerator to introduce the gas in the incinerator into the accommodating chamber; and

[0011] An exhaust component, one end of which is connected to the accommodating chamber, and the other end of which is used to be connected to the waste heat furnace to transport the gas in the accommodating chamber to the waste heat furnace.

[0012] The above drying device can at least achieve the following beneficial effects: the materials used to manufacture carbon molecular sieves will produce volatile organic matter, multi-carbon organic matter, carbon monoxide and hydrogen after carbonization. The traditional carbon molecular sieve solution is to burn these waste gases in the incinerator and then cool and discharge them through the waste heat furnace, which not only wastes a lot of heat sources, but also evaporates a lot of water resources. The present application introduces the high-temperature gas after combustion in the incinerator into the accommodating chamber of the drying furnace to heat the furnace, thereby drying the materials, effectively utilizing the heat energy of the waste gas, thereby replacing the traditional electric heating or natural gas heating method, and reducing the investment cost and operating cost of the equipment. At the same time, the temperature of the gas entering the accommodating chamber will also be cooled after heat exchange, and the gas in the accommodating chamber will be subsequently led out to the waste heat furnace for cooling. Since the gas has been heat exchanged and cooled in the accommodating chamber, the workload of the waste heat furnace and the water resources consumed will be reduced, which is beneficial to energy saving and water saving. In addition, the dried gas can be discharged smoothly, which can avoid the excessive pressure of the accommodating chamber, and ensure that the gas with a high enough temperature from the incinerator can be replaced in time in the accommodating chamber, thereby improving the drying efficiency. In summary, the drying device provided in the present application can effectively reduce production costs and improve the environmental protection level of the production process while ensuring drying efficiency.

Through the sequential connection design of the air intake joint, the air intake channel and the air intake part, the high-temperature gas in the incinerator can be smoothly introduced into the accommodating chamber of the drying furnace. The air intake channel is arranged through the furnace, and the high-temperature gas is evenly distributed through the air intake hole, so that the heat energy can be fully transferred to the material in the accommodating chamber, thereby improving the utilization efficiency of heat energy.

[0015] In one embodiment, a first groove is formed on the first partition, and the first groove faces the furnace and matches the outer peripheral surface of the furnace. The matching design of the first groove and the furnace makes the installation and removal of the first partition more convenient, and improves its supporting effect on the furnace.

[0016] In one embodiment, a second groove is formed on the second partition, and the second groove faces the furnace and matches the outer peripheral surface of the furnace.

The second sealing plate can be openably and closably covered on the second inspection port, and when the second sealing plate closes the second inspection port, it ensures that the inspection port can be tightly closed when the equipment is running to prevent gas leakage, thereby improving the safety of equipment operation. By providing a second inspection port on the second exhaust section and / or the second exhaust flow channel and equipping it with an openable and closable second sealing plate, the operator can easily open the inspection port, so that daily maintenance and troubleshooting can be completed in a shorter time, which significantly improves the convenience of equipment maintenance, reduces equipment downtime, and improves production efficiency and equipment utilization.

When the drying furnace is in standby mode, such as when there is no furnace core placed in the accommodating chamber, the furnace core is hoisted, or when maintenance is being performed, the first control valve and the second control valve can be closed, and the high-temperature gas in the incinerator will not enter the accommodating chamber through the air intake pipe.

[0020] In one embodiment, the drying device further includes a third control valve, and the third end of the air inlet pipe is connected to the third end of the exhaust pipe through the third control valve. When the drying furnace is in standby mode, such as when no furnace core is placed in the accommodating chamber, the furnace core is hoisted or repaired, the first control valve and the second control valve can be closed, and the third control valve can be opened. At this time, the high-temperature gas in the incinerator will not enter the accommodating chamber through the air inlet pipe, but the high-temperature gas in the incinerator can still flow into the third end of the exhaust pipe through the third end of the air inlet pipe, and then be transported to the waste heat furnace, that is, even if the drying furnace is in standby mode, the remaining components can still operate normally, thereby continuing the preparation of carbon molecular sieves, and avoiding the standby time being too long and affecting the production efficiency.

When the gland and the base are closed, they can enclose to form a closed accommodating chamber, effectively preventing the leakage of high-temperature gas, ensuring the safety and efficiency of the drying process, and reducing energy loss. Through reasonable design, it is ensured that the gland and the base can be firmly locked when closed to prevent accidental opening under high temperature and high pressure conditions, thereby improving the safety of equipment operation.

[0022] In one of the embodiments, a limiting groove is provided on the top of the base, and the rotating shaft of the furnace core is rotatably embedded in the limiting groove.

The rotating shaft of the furnace core is rotatably embedded in the limiting groove, so that the furnace core can rotate freely during the drying process, facilitating uniform heating and drying, and improving the drying effect and efficiency. The existence of the limiting groove provides a clear positioning reference, ensuring that the furnace core is always in the correct position during installation and operation, reducing installation errors and operating difficulties. Since the rotating shaft of the furnace core can be easily embedded and removed, it is convenient to inspect, clean and maintain the furnace core when necessary, reducing the complexity and time cost of maintenance.

The traditional carbon molecular sieve solution is to burn these waste gases in the incinerator and then cool and discharge them through the waste heat furnace, which not only wastes a lot of heat sources, but also evaporates a lot of water resources. The present application introduces the high-temperature gas after combustion in the incinerator into the containing chamber of the drying furnace to heat the furnace, thereby drying the material, effectively utilizing the heat energy of the waste gas, thereby replacing the traditional electric heating or natural gas heating method, and reducing the investment cost and operating cost of the equipment. At the same time, the temperature of the gas entering the containing chamber will also be cooled after heat exchange, and the gas in the containing chamber will be subsequently led out to the waste heat furnace for cooling. Since the gas has been cooled in the containing chamber by heat exchange, the workload of the waste heat furnace and the water resources consumed will be reduced, which is conducive to energy saving and water saving. After being cooled in the waste heat furnace, the gas can also enter the alkali spray device and finally be discharged through the chimney.

At this time, the high-temperature gas in the incinerator will not enter the accommodating chamber 130 through the air inlet pipe 500, but the high-temperature gas in the incinerator can still flow into the third end of the exhaust pipe 600 through the third end of the air inlet pipe 500, and then be transported to the waste heat furnace, that is, even if the drying furnace 100 is in standby, the remaining devices can still operate normally, thereby continuing the preparation of carbon molecular sieves, avoiding the standby time being too long and affecting the production efficiency.

[0049] Specifically, in some of the embodiments, a fan may be provided on the air inlet pipe 500 and / or the air outlet pipe 600 to accelerate the flow of gas.

[0050] See also Figure 1 In some embodiments, the furnace 120 includes a pressure cover 122 and a base 121, the pressure cover 122 is connected to the base 121 and can move relative to the base 121 to open and close, and the pressure cover 122 and the base 121 are closed to form the accommodating cavity 130. For example, in Figure 1In the illustrated embodiment, the pressure cover 122 is rotatably connected to the base 121 and can be flipped relative to the base 121 to open and close. The design of the pressure cover 122 and the base 121 makes the opening and closing operation of the furnace 120 easier, and the user can easily open or close the furnace 120, reducing the complexity and time of the operation, reducing the time for loading and unloading, and improving production efficiency. When the pressure cover 122 and the base 121 are closed, they can enclose to form a closed accommodating chamber 130, effectively preventing the leakage of high-temperature gas, ensuring the safety and efficiency of the drying process, and reducing energy loss. Through reasonable design, it is ensured that the pressure cover 122 and the base 121 can be firmly locked when closed, preventing accidental opening under high temperature and high pressure conditions, and improving the safety of equipment operation.

[0051] Specifically, Figure 5 As shown, in some embodiments, a limiting groove 123 is provided on the top of the base 121, and the rotating shaft 111 of the furnace 110 is rotatably embedded in the limiting groove 123. The design of the limiting groove 123 ensures the stable embedding of the rotating shaft 111 of the furnace 110 on the base 121, prevents the furnace 110 from deflecting or falling off during the rotation process, and enhances the stability and safety of the entire system. The rotating shaft 111 of the furnace 110 is rotatably embedded in the limiting groove 123, so that the furnace 110 can rotate freely during the drying process, which is convenient for uniform heating and drying, and improves the drying effect and efficiency. The existence of the limiting groove 123 provides a clear positioning reference, ensuring that the furnace 110 is always in the correct position during installation and operation, reducing installation errors and operating difficulties. Since the rotating shaft 111 of the furnace 110 can be easily embedded and removed, it is convenient to inspect, clean and maintain the furnace 110 when necessary, reducing the complexity and time cost of maintenance.

[0052] Specifically, Figure 1 and Figure 3 As shown, in some embodiments, the drying oven 100 further includes a seal 140, which is disposed on the pressure cover 122 or the base 121. When the pressure cover 122 and the base 121 are closed, the seal 140 is held between the pressure cover 122 and the base 121 to seal the accommodating cavity 130.

[0053] In addition, the present application also provides a carbon molecular sieve preparation device, which includes a carbonization furnace, an incinerator, a waste heat furnace and a drying device 10 as described in any of the above embodiments, wherein the drying device 10 is used to dry the material, the carbonization furnace is used to carbonize the material and transport the combustible gas generated during the carbonization process to the incinerator, and the incinerator is used to incinerate the combustible gas and transport the incinerated gas to the drying furnace 100 of the drying device 10 to dry the material.

[0054] The above-mentioned carbon molecular sieve preparation device, because it includes the drying device 10 described in any of the above-mentioned embodiments, the carbon molecular sieve preparation device also includes at least the following beneficial effects: after the material is baked, dehydrated, and ball-milled, the carbonization furnace can carbonize the material, and the material will produce volatile organic matter, multi-carbon organic matter, carbon monoxide, hydrogen and other gases after carbonization. The traditional carbon molecular sieve solution is to burn these waste gases in the incinerator, and then cool and discharge them through the waste heat furnace, which not only wastes a lot of heat sources, but also evaporates a lot of water resources. The present application introduces the high-temperature gas after combustion in the incinerator into the accommodating cavity 130 of the drying furnace 100 to heat the furnace 110, thereby drying the material, effectively utilizing the heat energy of the waste gas, thereby replacing the traditional electric heating or natural gas heating method, and reducing the investment cost and operating cost of the equipment. At the same time, the temperature of the gas entering the accommodating chamber 130 will also be cooled down after heat exchange, and the gas in the accommodating chamber 130 will be subsequently led out to the waste heat furnace for cooling. Since the gas has been cooled by heat exchange in the accommodating chamber 130, the workload of the waste heat furnace and the water resources consumed will be reduced, which is beneficial to energy and water conservation. After being cooled in the waste heat furnace, the gas can also enter the alkali spray device again and finally be discharged through the chimney. In summary, the carbon molecular sieve preparation device provided in the present application can effectively reduce production costs and improve the environmental protection level of the production process while ensuring the drying efficiency.
