Description

Technical Field

[0001] This application relates to the field of biomass carbonization technology, specifically to a biomass carbonization catalytic reaction device. Background Technology

[0002] Biomass carbonization is the process of converting organic materials (such as agricultural and forestry waste, straw, sawdust, etc.) into biochar, combustible gas and liquid products through high-temperature pyrolysis under anaerobic or oxygen-limited conditions.

[0003] For example, the patent with announcement number CN205347328U specifically discloses a laboratory biomass pyrolysis carbonization reaction device. The device loads the processed biomass raw materials into a tubular carbonization furnace, then loads the tubular carbonization furnace into a heating furnace, closes the furnace door, introduces nitrogen into the tubular carbonization furnace, starts the heating furnace, and at the same time, the steam generated in the carbonization furnace enters the condenser through the gas outlet pipe for condensation. After the reaction is completed, the solid product biochar is taken out after the tubular reaction furnace cools to room temperature.

[0004] However, although the aforementioned patent can achieve the carbonization of biomass, when removing the biochar, it is necessary to wait for it to cool completely before removing it, and then the next batch of carbonization can be carried out. This results in low equipment utilization and increased time costs.

[0005] Therefore, it is necessary to provide a biomass carbonization catalytic reaction device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0009] Furthermore, a pad is provided at the top of the heating furnace, and the reaction assembly includes a reaction vessel installed inside the heating furnace. The reaction vessel has a feed inlet and an exhaust pipe.

[0010] Furthermore, a gas guide pipe is provided on the gasket, and at least two sets of branch pipes are provided on the gas guide pipe, with the end of the branch pipe away from the gas guide pipe extending into the interior of the reaction vessel.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figures 1-2 As shown, this application provides a biomass carbonization catalytic reaction device, including a heating furnace 1. The heating furnace 1 is provided with an air inlet pipe 101 and an exhaust pipe. The air inlet pipe 101 is connected to an external heating device so that hot air can be introduced into the heating furnace 1 through the air inlet pipe 101 to heat the interior of the heating furnace 1.

[0029] A pad (not shown in the figure) is provided at the upper end of the heating furnace 1. The pad is located at the opening of the heating furnace 1 to facilitate sealing of the heating furnace 1.

[0030] The heating furnace 1 is equipped with a reaction assembly 2, which is used for the thermal decomposition and carbonization reaction of biomass. Specifically:

[0031] The reaction assembly 2 includes a reaction tank 21 installed inside the heating furnace 1. The reaction tank 21 has a feed inlet to allow the processed biomass to be fed into the reaction tank 21. The reaction tank 21 is heated by the heating furnace 1 to thermally decompose and carbonize the biomass. The discharge end of the reaction tank 21 extends out of the bottom of the heating furnace 1 to discharge the biochar. The discharge end of the reaction tank 21 can be controlled to open and close by a valve.

[0032] Continue to refer to Figure 2 An outlet pipe 22 is provided on the reaction tank 21. The outlet pipe 22 can be connected to the subsequent waste gas treatment equipment to treat the waste gas generated by thermal decomposition and carbonization. A guide pipe 24 is provided on the gasket plate. Multiple branches 241 are provided on the guide pipe 24. The end of the branch pipe 241 away from the guide pipe 24 extends into the interior of the reaction tank 21.

[0033] It should be noted that the gas pipe 24 can be connected to an external nitrogen source so that nitrogen can be introduced into the reaction vessel 21 through the gas pipe 24 and the branch pipe 241, thereby avoiding the reaction of oxygen with biochar at high temperature, reducing the generation of ash and impurities, and improving the purity of biochar.

[0034] A catalyst tube 23 is installed through the gas delivery pipe 24. The catalyst tube 23 is connected to an external catalyst storage device, and the end of the catalyst tube 23 away from the gas delivery pipe 24 extends into the interior of the reaction tank 21 to facilitate the introduction of catalyst into the interior of the reaction tank 21, thereby accelerating the process of biomass thermal decomposition and carbonization. The catalyst can be a dolomite catalyst or other catalyst that is harmless after deactivation.

[0035] A cooling component 3 is provided at the bottom of the heating furnace 1, which is used for cooling the biochar.

[0036] like Figure 2 As shown, the cooling assembly 3 includes an outer shell 31 fixedly installed at the bottom of the heating furnace 1. An inner liner 33 is provided inside the outer shell 31. The inner liner 33 is located below the discharge end of the reaction tank 21 to receive biochar. The inner liner 33 is conical in shape. A discharge pipe 34 is provided at the bottom of the inner liner 33. The discharge pipe 34 has a valve to control the subsequent discharge of biochar.

[0037] A coil 32 is provided on the outer surface of the inner liner 33. Both ends of the coil 32 can be connected to external refrigeration equipment. Under the drive of the refrigeration equipment, the heat transfer medium is introduced into the coil 32 for circulation to cool the inner liner 33 and thus cool the biochar.

[0038] A collection component 4 is provided on the cooling component 3, which is used to collect and quickly remove biochar;

[0039] like Figures 2-3 As shown, the collection component 4 includes a discharge frame 41 fixedly installed on the discharge pipe 34. The discharge frame 41 has a groove inside, and a collection box 42 is slidably disposed inside the groove so that the cooled biochar can enter the discharge frame 41 from the discharge pipe 34 and fall into the collection box 42 for collection.

[0040] It should be noted that in this application, a filter screen can be provided in the collection box 42 to separate the liquids such as biochar and tar. The collection box 42 has a handle to facilitate pulling out the collection box 42.

[0041] Two sets of screws 44 are fixedly installed on the material feeding frame 41, and two sets of through holes 43 adapted to the screws 44 are opened through the collection box 42 so that when the collection box 42 is inserted into the groove, the screws 44 are inserted into the through holes 43. Nuts 45 are provided on the screws 44. After the screws 44 are inserted into the through holes 43, the bolts are screwed onto the nuts 45 until they abut against the surface of the collection box 42 to fix the collection box 42.

[0042] In summary, during use, the treated biomass is fed into the reaction tank 21, and the heating furnace 1 is started to heat the reaction tank 21 to thermally decompose and carbonize the biomass. At the same time, the waste gas generated by carbonization is discharged from the exhaust pipe 22 into the subsequent waste gas treatment equipment for treatment. Nitrogen and catalyst are introduced into the reaction tank 21 through the gas guide pipe 24 and the catalytic pipe 23 to accelerate the process of thermal decomposition and carbonization of biomass and ensure the purity of the biomass after thermal decomposition and carbonization. After the thermal decomposition and carbonization is completed, it is discharged into the cooling component 3 for cooling. At this time, subsequent biomass can be fed into the reaction tank 21 again for thermal decomposition and carbonization reaction. The biochar in the cooling component 3 is cooled and discharged into the collection component 4 for collection. After solid-liquid separation, it can be taken out.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
