Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, and in particular to a biomass gas co-production device with pretreatment. Background Technology

[0002] Carbonization furnace is a core piece of equipment used for carbonization of materials such as biomass and coal. By creating an oxygen-deficient environment in a closed or semi-closed space, the material is pyrolyzed at high temperature, separating the moisture, volatile matter and other substances in the material, and finally transforming it into carbon-based products such as charcoal and charcoal powder.

[0003] A carbonization furnace generally includes a furnace body, a heating device, a temperature measurement and control system, and an exhaust and feeding / discharging mechanism. Currently, most carbonization furnaces, during carbonization operations, directly release the high-temperature flue gas generated by heating the carbonization chamber into the atmosphere after treatment, resulting in heat waste. Therefore, the existing Chinese utility model patent with publication number CN223118378U, entitled "Carbonization Furnace with Internal Preheating," addresses this issue. This application includes a furnace body, a ring pipe, and multiple preheating pipes. The ring pipe is fixed to the outer wall of the furnace body, and the multiple preheating pipes are located on one side of the ring pipe and are fixedly connected. One end of each preheating pipe is equipped with a flow guide. The preheating mechanism allows exhaust gas to be discharged into the flue gas heat conduction tube through the exhaust pipe. The flue gas heat conduction tube brings the high-temperature exhaust gas into contact with the outer wall of the preheating tank. The circulation pump is started to generate suction in the suction pipe, which draws the hot liquid inside the preheating tank into the booster pipe. The liquid is then injected into multiple preheating tubes through the ring pipe, thus preheating the furnace body. However, when preheating the furnace body, it is necessary to simultaneously heat the furnace body. Therefore, the furnace body is in a normal temperature rise state, and after the furnace body is heated to the rated temperature, the heat of the flue gas cannot be further utilized, so the flue gas used to heat the furnace body cannot be continuously used in the production process. Utility Model Content

[0004] The purpose of this invention is to provide a biomass gasification and co-production device with pretreatment, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A biomass gas co-production device with pretreatment includes a carbonization furnace shell, a flue gas treatment device, and a preheating drying box. A carbonization chamber is fixedly connected inside the carbonization furnace shell, and a second exhaust pipe is fixedly connected to the carbonization furnace shell. A first fan is fixedly connected to the flue gas treatment device, and the first fan is electrically connected to an external main controller via a connecting wire. The second exhaust pipe is connected to the first fan via a pipe. An outlet is fixedly connected to the outside of the flue gas treatment device. Several first crossbeams are fixedly connected inside the preheating drying box, and several second crossbeams are fixedly connected to the first crossbeams. Several first tracks are fixedly connected to the second crossbeams, and trolleys are slidably connected to the several first tracks. A basket is fixedly connected to the trolley, and a basket door is rotatably connected to one side of the basket. A box door is fixedly connected to the front side of the trolley and the basket. A diversion hood is fixedly connected to one side of the preheating drying box, and a second fan is fixedly connected to one side of the diversion hood. The side of the second fan opposite to the diversion hood is connected to the outlet via a pipe.

[0007] As a further optimization of this utility model, a first exhaust pipe is fixedly connected to the center of the preheating drying box. When the recovered waste heat heats and dries the wood in the basket, the generated gas can be discharged through the first exhaust pipe.

[0008] As a further optimization of this utility model, two supports are fixedly connected to the front side of the preheating drying box, and a second track is fixedly connected to the supports, so that the wood or other biomass materials that have been preheated and dried in the preheating drying box can be moved out by a trolley and transferred to the carbonization chamber. A limit block is fixedly connected to the second track to prevent the trolley from detaching from the second track.

[0009] As a further optimization of this utility model, the basket is fixedly connected with several partitions, which can divide the space inside the basket to prevent excessive accumulation and compression of preheating materials and ensure heat flow between preheating and drying materials.

[0010] As a further optimization of this utility model, the second crossbeam is a hollow tube structure, and several air outlets are opened on the side of the second crossbeam away from the diversion hood. The diversion hood diverts the recovered hot air, so that some of the hot air is directly transmitted to the position in the preheating drying box away from the air inlet through several second crossbeams, thereby ensuring that the heat is evenly distributed in the preheating drying box.

[0011] As a further optimization of this utility model, the preheating drying box has an air inlet on the side near the flow divider, so as to realize the connection between the flow divider and the inner cavity of the preheating drying box.

[0012] As a further optimization of this utility model, a diversion plate is fixedly connected inside the diversion hood. The inner cavity of the diversion hood located above the diversion plate can guide hot air into several second crossbeams, while the inner cavity of the diversion hood located below the diversion plate can guide hot air directly into the preheating drying oven through the air inlet, thereby realizing the diversion of hot air.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention discloses a biomass gas-carbon cogeneration device with pretreatment. The waste heat of the high-temperature flue gas generated during carbonization is treated and then introduced into a preheating drying chamber through a diversion hood and a second fan, providing a heat source for the pretreatment of biomass raw materials and avoiding waste caused by direct heat emission. The diversion plate and the hollow structure of the second crossbeam cooperate to ensure that the hot air is evenly distributed in the chamber. Combined with the partition rack in the basket, it ensures that the raw materials are heated evenly and prevents accumulation from affecting the drying effect, greatly improving energy utilization efficiency, shortening the carbonization cycle, and reducing energy consumption.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5As shown, this utility model provides a biomass gas co-production device with pretreatment, including a carbonization furnace shell 1, a flue gas treatment device 2, and a preheating drying box 3. A carbonization chamber 4 is fixedly connected inside the carbonization furnace shell 1. A second exhaust pipe 25 is fixedly connected to the carbonization furnace shell 1. A first fan 5 is fixedly connected to the flue gas treatment device 2. The first fan 5 is electrically connected to an external main controller via a connecting wire, and the second exhaust pipe 25 is connected to the first fan 5 via a pipe. An exhaust end 6 is fixedly connected to the outside of the flue gas treatment device 2. Several [unclear - possibly related to equipment or components] are fixedly connected inside the preheating drying box 3. A first crossbeam 7 is fixedly connected to several second crossbeams 8. Several first tracks 9 are fixedly connected to the second crossbeams 8. A trolley 10 is slidably connected to the several first tracks 9. A basket 11 is fixedly connected to the trolley 10. A basket door 12 is rotatably connected to one side of the basket 11. A box door 13 is fixedly connected to the front side of the trolley 10 and the basket 11. A diversion hood 14 is fixedly connected to one side of the preheating drying box 3. A second fan 15 is fixedly connected to one side of the diversion hood 14. The side of the second fan 15 opposite to the diversion hood 14 is connected to the air outlet 6 through a pipe.

[0023] like Figures 2-4 As shown, two supports 17 are fixedly connected to the front of the preheating drying chamber 3. A second track 18 is fixedly connected to the supports 17, so that the wood or other biomass materials that have been preheated and dried in the preheating drying chamber 3 can be moved out by the trolley 10 and transferred to the carbonization chamber 4. A limit block 19 is fixedly connected to the second track 18 to prevent the trolley 10 from detaching from the second track 18. Several partition racks 22 are fixedly connected to the basket 11 to divide the space inside the basket 11, prevent the preheated materials from being over-accumulated and squeezed, and ensure the heat flow between the preheated drying materials.

[0024] like Figures 2-4 As shown, a first exhaust pipe 16 is fixedly connected to the center of the preheating drying chamber 3. After the recovered waste heat heats and dries the wood in the basket 11, the generated gas can be discharged through the first exhaust pipe 16. The second crossbeam 8 is a hollow tube structure. Several air outlets 20 are opened on the side of the second crossbeam 8 away from the diversion hood 14. The diversion hood 14 diverts the recovered heat and hot air, so that some of the hot air is directly transmitted through several second crossbeams 8 to the position in the preheating drying chamber 3 away from the air inlet 21, thereby ensuring that the heat in the preheating drying chamber 3 is evenly distributed. An air inlet 21 is opened on the side of the preheating drying chamber 3 near the diversion hood 14 to realize the communication between the diversion hood 14 and the inner cavity of the preheating drying chamber 3.

[0025] like Figures 4-5As shown, a flow divider plate 24 is fixedly connected inside the flow divider 14. The inner cavity of the flow divider 14 located above the flow divider plate 24 can guide hot air into several second crossbeams 8, while the inner cavity of the flow divider 14 located below the flow divider plate 24 can guide hot air directly into the preheating drying oven 3 through the air inlet 21, thus realizing the diversion of hot air.

[0026] It should be noted that this utility model is a biomass gasification and carbonization cogeneration device with pretreatment. Before carbonization, the biomass raw materials to be preheated and dried are placed in the basket 11 and separated by the divider 22 to avoid accumulation and affect heating. After the biomass raw materials are placed, the basket door 12 is rotated and closed by the two latches 23 on one side of the basket door 12. Then, the basket 11 and the biomass raw materials inside are pushed from the second track 18 into the first track 9 inside the preheating and drying box 3 by the trolley 10 and the box door 13 is locked.

[0027] High-temperature flue gas is generated during the carbonization process in the carbonization chamber 4. This flue gas is discharged through the second exhaust pipe 25. The external main controller controls the first fan 5 to start, which draws the flue gas to the flue gas treatment equipment 2 for purification. The treated flue gas, carrying residual heat, is discharged from the outlet 6. The second fan 15 guides this residual heat flue gas into the diversion hood 14. The diversion plate 24 inside the diversion hood 14 plays a diversion role. Part of the hot air enters the preheating drying box 3 directly through the air inlet 21, while the other part is guided to the hollow structure of the second crossbeam 8, and then evenly distributed through multiple air outlets 20 on the second crossbeam 8. The heat distribution inside the preheating drying chamber 3 is evenly distributed, thereby achieving the drying pretreatment of the biomass raw materials in the heating basket 11. The water vapor and other gases generated during the pretreatment process are discharged through the first exhaust pipe 16 on the preheating drying chamber 3. After the raw materials are dried, the chamber door 13 is opened and the trolley 10 is pulled to slide along the first track 9 to the second track 18 on the front side of the preheating drying chamber 3. The limiting block 19 on the second track 18 can prevent the trolley 10 from slipping. The staff can easily transfer the pretreated raw materials on the trolley 10 to the carbonization chamber 4 for carbonization.
