Abstract
Description
Technical Field
[0001] The utility model belongs to the field of carbonization furnaces, and in particular relates to a flow guide structure of a carbonization furnace. Background Art
[0002] The carbonization furnace is used to carbonize sludge. During the carbonization process, the carbonization furnace is in a high temperature state, which evaporates the water in the sludge while retaining the carbon value in the sludge to the maximum extent. A large amount of gas will be produced after the evaporation of the water, and the temperature of the gas is relatively high. When the gas is discharged, it is often discharged directly, but the temperature of the gas is relatively high, and it will be discharged around the carbonization furnace when discharged, which will not only cause danger to the operators around the carbonization furnace, but also cause the temperature of the carbonization furnace at the gas discharge point to be relatively high, thereby shortening the service life of the carbonization furnace. Utility Model Content
[0003] In view of the above-mentioned deficiencies, the utility model provides a flow guide structure of a carbonization furnace, which can reduce the temperature of the gas discharged from the carbonization furnace.
[0004] The utility model is realized by the following technical solutions:
[0005] A guide structure for a carbonization furnace, the carbonization furnace includes a furnace body, the furnace body is used to accommodate sludge, a smoke outlet is formed on the top of the furnace body, the furnace body includes an inner furnace body for accommodating sludge and an outer furnace body located outside the inner furnace body, the guide structure includes a first guide component arranged at the smoke outlet and connected to the interior of the furnace body, the first guide component includes a first guide section passing through the outer furnace body and connected to the inner furnace body, and a second guide section extending from the first guide section to the smoke outlet; the guide structure also includes a second guide component arranged at the smoke outlet, the second guide component includes a second guide member located in the smoke outlet and a circulation member arranged between the inner furnace body and the outer furnace body, the circulation member is connected to the second guide member, and the second guide member transports cooling gas to the circulation member. The first guide component can guide the excess gas when the material is carbonized. In the process of carbonizing the sludge, the carbonization furnace not only has a heating process, that is, the material is carbonized, but also needs to be cooled after the carbonization is completed, so as to facilitate the removal of the carbonized product formed after the carbonization. Therefore, by setting the second guide component, the cooling gas used for cooling can be guided to the surrounding of the inner furnace body, so as to achieve the cooling of the inner furnace body by lowering the temperature around the inner furnace body, so that after the carbonization is completed, the temperature inside the inner furnace body can be reduced to room temperature more quickly, which is convenient for taking out the carbonized product after carbonization, so as to improve the processing efficiency of the carbonized product.
[0006] Furthermore, along the extension direction of the second guide section, a plurality of baffles are arranged at intervals on the inner wall of the second guide section, and each baffle is hingedly connected to the second guide section. Since the second guide section can discharge the gas in the first guide section, the baffles can be arranged to block the gas, so that the discharged gas is more dispersed, and the surrounding temperature is prevented from being too high due to excessive concentration of gas.
[0007] Furthermore, a cover plate is provided at the end of the second guide section, and the cover plate is hingedly connected to the adjacent baffle plate by a first connecting rod, and the adjacent baffle plates are hingedly connected by a second connecting rod. In order to ensure that the generated gas can be discharged in time, a cover plate is provided at the end of the second guide section, and the cover plate and the plurality of baffle plates are linked to each other. When the cover plate is moved, the entire baffle plate can be driven to move, thereby increasing the space for gas flow at the second guide section. While achieving gas blocking, the normal discharge of the gas will not be affected, and the gas accumulation at the second guide section to cause danger is avoided.
[0008] Furthermore, the first connecting rod and the second connecting rod are both connected to the inner wall side of the baffle away from the second guide section, so that after the cover plate is opened, the baffle plate can be rotated to a larger range through the cover plate, so that the smoke can be quickly discharged from the second guide section.
[0009] Furthermore, the inner diameter of the first guide section gradually increases from the middle to both sides. A large amount of gas is generated in the inner furnace body, which will increase the pressure to quickly press the gas out to the first guide section, and the middle part of the first guide section is smaller, so that the inner furnace body and the outside are separated by the middle part of the first guide section, preventing the gas with lower temperature in the outside from flowing to the inner furnace body.
[0010] Furthermore, the middle of the first flow guide section is located between the inner furnace body and the outer furnace body. The middle of the first flow guide section is smaller in size, so when connected to the inner furnace body, the middle area of the first flow guide section can also play a limiting role to prevent the first flow guide section from continuing to extend into the inner furnace body.
[0011] Furthermore, the second flow guide comprises an air inlet pipe and an air outlet pipe connected to the circulation member, and a connecting pipe is further connected between the air inlet pipe and the air outlet pipe. The second flow guide is used to cool the carbonized product after carbonization. At the same time, since the second flow guide is also arranged at the smoke outlet, the second flow guide can also cool the second flow guide section, thereby reducing the temperature of the gas discharged from the second flow guide section.
[0012] Furthermore, a first valve is provided at the connection between the air inlet pipe and the circulation part, and the first valve is located at the rear side of the connection between the air inlet pipe and the connecting pipe; a second valve is provided at the connection between the air inlet pipe and the connecting pipe, and the second valve is located at the connecting pipe. When the inner furnace body needs to be cooled, the first valve is opened and the second valve is closed at the same time, and the cooling gas will enter the circulation part through the air inlet pipe and be discharged from the air outlet pipe. When the second guide section needs to be cooled, the first valve can be closed and the second valve can be opened at the same time.
[0013] Furthermore, the second guide member is arranged around the second guide section, and the air inlet pipe is located inside the air outlet pipe. The temperature of the cooling gas in the air inlet pipe is lower than that in the air outlet pipe, so the air inlet pipe is located inside, which is more convenient for cooling the second guide section.
[0014] Furthermore, an installation gap is formed between the circulation member and the outer wall of the inner furnace body. The circulation member and the inner furnace body are not in contact, so when the inner furnace body is cooled, the temperature inside the inner furnace body is ensured to be slowly reduced, which is more conducive to the formation of carbonized products.

[0024] like Figures 1 to 3 A flow guide structure of a carbonization furnace is shown, and the carbonization furnace is used to carbonize sludge. During the carbonization process, the carbonization furnace will be in a high temperature state, so that the moisture in the sludge can be evaporated, while the carbon value in the sludge can be retained to the maximum extent. The carbonization furnace includes a furnace body, and the furnace body is used to accommodate the sludge. A smoke outlet 3 is formed on the top of the furnace body. During the carbonization process of the sludge, the residual moisture in the sludge will be evaporated, so gas will be generated, and the gas needs to be discharged in time to stabilize the pressure in the furnace body.
[0025] Specifically, the furnace body includes an inner furnace body 1 for accommodating sludge and an outer furnace body 2 located outside the inner furnace body 1, the guide structure includes a first guide component arranged at the smoke outlet 3 and connected to the interior of the furnace body, the first guide component includes a first guide section 41 passing through the outer furnace body 2 and connected to the inner furnace body 1, and a second guide section 42 extending from the first guide section 41 to the smoke outlet 3; the first guide component can discharge the gas generated during the carbonization of the inner furnace body 1 in time to keep the pressure in the inner furnace body 1 in a stable state, and at the same time, the guide structure also includes a second guide component arranged at the smoke outlet 3, the second guide component includes a second guide member located in the smoke outlet 3 and a circulation member 53 arranged between the inner furnace body 1 and the outer furnace body 2, the circulation member 53 and the second guide member The second flow guide member is connected, and the second flow guide member conveys cooling gas to the circulation member 53; the first flow guide member can realize the diversion of excess gas when the material is carbonized, and the carbonization furnace will have not only a heating process, that is, carbonizing the material, but also cooling after the carbonization is completed, so as to facilitate the removal of the carbonized product formed after carbonization. Therefore, by setting the second flow guide member, the cooling gas used for cooling can be diverted to the surrounding of the inner furnace body 1, so as to achieve the cooling of the inner furnace body 1 by lowering the temperature around the inner furnace body 1, so that after the carbonization is completed, the temperature inside the inner furnace body 1 can be reduced to room temperature more quickly, so as to facilitate the removal of the carbonized product after carbonization, so as to improve the processing efficiency of the carbonized product.
[0026] As an embodiment of the present application, the inner diameter of the first guide section 41 gradually increases from the middle to both sides; since the first guide component can discharge the gas at the inner furnace body 1, the first guide component plays a role in connecting the inner furnace body 1 with the outside world. Since the first guide section 41 is a component of the first guide section 41, the first guide section 41 will also be connected with the outside world, but since the first guide section 41 is closer to the inner furnace body 1, by making the first guide section 41 a structure with a small middle and large ends, a large amount of gas is generated at the inner furnace body 1, and the pressure will be increased to quickly press the gas out to the first guide section 41, and the middle part of the first guide section 41 is smaller in size, so that the inner furnace body 1 and the outside world are separated by the middle part of the first guide section 41, so as to prevent the gas with a lower temperature in the outside world from flowing to the inner furnace body 1.
[0027] Preferably, the middle part of the first guide section 41 is located between the inner furnace body 1 and the outer furnace body 2; the middle part of the first guide section 41 is a smaller area, so it is located between the inner furnace body 1 and the outer furnace body 2, and the part of the first guide section 41 extending downward from the middle is connected to the inside of the inner furnace body 1, and the part extending upward is connected to the second guide section 42. At the same time, the middle part of the first guide section 41 is smaller in size, so when it is connected with the inner furnace body 1, the middle area of the first guide section 41 can also play a limiting role to prevent the first guide section 41 from continuing to extend into the inner furnace body 1.
[0028] As an embodiment of the present application, along the extension direction of the second guide section 42, a plurality of baffles 421 are arranged at intervals on the inner wall of the second guide section 42, and each baffle 421 is hingedly connected to the second guide section 42; since the second guide section 42 can discharge the gas in the first guide section 41, the baffle 421 can be provided to block the gas, thereby making the discharged gas more dispersed, thereby preventing the gas from being too concentrated and causing the surrounding temperature to be too high.
[0029] Preferably, a cover plate 6 is provided at the end of the second guide section 42, and the cover plate 6 is hingedly connected to the adjacent baffle plates 421 by a first connecting rod 422, and the adjacent baffle plates 421 are hingedly connected by a second connecting rod 423; since the amount of gas generated in each stage during the carbonization of the sludge will be different, in the stage of water removal, since the amount of gas generated is small, the impact of the gas on the baffle plate is small, and even if the baffle plate 421 blocks the gas, it will not affect the discharge of the gas. When in the carbonization stage, the amount of gas generated at this time increases. Therefore, in order to ensure that the generated gas can be discharged in time, a cover plate 6 is provided at the end of the second guide section 42, and the cover plate 6 and multiple baffle plates 421 are linked. When the cover plate 6 is moved, the overall baffle plate 421 can be driven to move, thereby increasing the space for gas flow at the second guide section 42. While achieving gas blocking, it will not affect the normal discharge of the gas, thereby avoiding gas accumulation at the second guide section 42 to cause danger.
[0030] In the present application, the first connecting rod 422 and the second connecting rod 423 are both connected to the side of the inner wall of the baffle plate 421 away from the second guide section 42; so that after opening the cover plate 6, the baffle plate 421 can be rotated to a larger range through the cover plate 6, so that the smoke can be quickly discharged from the second guide section 42.
[0031] As an embodiment of the present application, the second flow guide member includes an air inlet pipe 51 and an air outlet pipe 52 connected to the circulation member 53, and a connecting pipe 54 is also connected between the air inlet pipe 51 and the air outlet pipe 52; the second flow guide member is used to cool the carbonized product after carbonization. At the same time, since the second flow guide member is also arranged at the smoke outlet 3, the second flow guide member can also cool the second flow guide section 42, thereby reducing the temperature of the gas discharged from the second guide section 42.
[0032] Preferably, a first valve 7 is provided at the connection point between the air inlet pipe 51 and the circulation part 53, and the first valve 7 is located on the rear side of the connection point between the air inlet pipe 51 and the connecting pipe 54; a second valve 8 is provided at the connection point between the air inlet pipe 51 and the connecting pipe 54, and the second valve 8 is located at the connecting pipe 54; when it is necessary to cool the inner furnace body 1, the first valve 7 is opened and the second valve 8 is closed at the same time, at this time, the cooling gas will enter the circulation part 53 through the air inlet pipe 51 and be discharged from the air outlet pipe 52, and when it is necessary to cool the second guide section 42, the first valve 7 can be closed and the second valve 8 can be opened at the same time.
[0033] Preferably, the second guide member is arranged around the second guide section 42, and the air inlet pipe 51 is located on the inner side of the air outlet pipe 52; the temperature of the cooling gas in the air inlet pipe 51 is lower than the temperature in the air outlet pipe 52, so the air inlet pipe 51 is located on the inner side, which is more convenient for cooling the second guide section 42.
[0034] Preferably, an installation gap is formed between the circulation member 53 and the outer wall of the inner furnace body 1; the circulation member 53 does not contact the inner furnace body 1, so when the inner furnace body 1 is cooled, the temperature inside the inner furnace body 1 is ensured to decrease slowly, which is more conducive to the formation of carbonized products.
[0035] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
