Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for distillation furnaces, specifically to an anti-clogging structure for a Fushun-type distillation furnace with dual fire channels. Background Technology

[0002] The Fushun-type dry distillation furnace is an internally heated dry distillation furnace specifically designed for processing blocky oil shale. It is one of the most mature furnace types in the world for dry distilling and refining blocky oil shale. During the dry distillation of oil shale, generated gas is supplied to the mixing chamber of the dry distillation furnace, while hot gas is also supplied to the furnace. The hot gas then enters the mixing chamber and is mixed. After mixing, the gas is injected into the dry distillation section of the furnace through the fire channel in the middle of the inner arch platform. Because the entrance of the arch platform has an inclined and variable diameter structure, and a large amount of dust particles are generated during the dry distillation of oil shale, the gas carrying dust particles passes through the inclined sidewall of the fire channel during the dry distillation process. The friction of the wall surface forms eddies, which can easily cause dust particles to adhere to and block the channels of the fire channel, affecting the stability and efficiency of the subsequent dry distillation process.

[0005] Furthermore, a gas supply pipe is fixedly connected to the outer surface of the main body, with the end of the gas supply pipe away from the main body extending through to the outside of the shell. The main body includes: Ash removal assembly: The ash removal assembly is installed inside the main body and is used to remove ash during the dry distillation process.

[0006] Furthermore, the auxiliary mechanism includes an arch platform fixedly connected inside the main body, and the auxiliary mechanism also includes: The sliding assembly is installed inside the arch platform to create a shear flow of flue gas during the dry distillation process, thereby achieving self-cleaning. The connecting component is installed on top of the sliding component.

[0007] Furthermore, the swing mechanism includes an annular frame disposed on the side wall of the connecting assembly, and the swing mechanism also includes: Deformation assembly, which is installed on the outer surface of the ring frame, is used to guide the rising flue gas; The movable component is installed on the side wall of the deformation component to reduce flue gas backflow.

[0008] Furthermore, the main body includes an ash dish rotatably connected to the bottom of the main body, a base plate fixedly connected to the bottom of the ash dish, and an air outlet pipe fixedly connected to the middle of the base plate; A geared disc is fixedly connected to the bottom of the chassis, and a motor is installed on the outer surface of the geared disc. The output end of the motor is meshed with the geared disc.

[0009] Furthermore, the side wall of the arch platform is provided with several oblique holes, and a fixing ring is fixedly connected inside the arch platform; The sliding assembly includes two telescopic rods fixedly connected to the inner wall of the arch. A conical ring is fixedly connected to one end of the two telescopic rods away from the arch. Several circular holes are opened on the outer surface of the conical ring.

[0010] Furthermore, several sliding frames are fixedly connected to the bottom of the conical ring, four bending plates are fixedly connected to the top of the conical ring, and several annular grooves are opened on the inner wall of the conical ring. Several of the bent plate sidewalls are in contact with the fixing ring.

[0011] Furthermore, the connecting assembly includes a connecting ring rotatably connected between the four bent plates, and a telescopic frame is fixedly connected inside the connecting ring; A limit plate is fixedly connected to the bottom of the telescopic frame, and the limit plate is fixedly connected to the inner wall of the conical ring.

[0012] Furthermore, the ring frame is fixedly connected to the bottom outer wall of the connecting ring; The deformation component includes a limiting frame that is slidably connected inside the sliding frame, and a bending ring is fixedly connected to one end of the limiting frame away from the sliding frame; The sidewall of the bending ring contacts the outer surface of the ring frame. Several rectangular plates are fixedly connected to the side of the bending ring away from the limiting frame. Several holes are opened on the sidewall of the rectangular plates.

[0013] Furthermore, the movable component includes a C-shaped frame fixedly connected to the side wall of the rectangular plate, and a curved plate is rotatably connected inside the C-shaped frame. The side wall of the curved plate is provided with several holes. Two limiting springs are fixedly connected to the side of the curved plate near the rectangular plate, and the ends of the two limiting springs away from the curved plate are fixedly connected to the side wall of the rectangular plate. An auxiliary spring is fixedly connected to the side wall of the C-shaped frame, and the side of the auxiliary spring away from the C-shaped frame is fixedly connected to the side wall of the conical ring.

[0014] The present invention has the following beneficial effects: 1. In this invention, when multiple bending plates are bent and deformed, the flow channel at the center of the conical ring can be reduced and the flow velocity of gas through this channel can be accelerated. At the same time, through the flow pressure difference of gas through the middle of the conical ring and the channel between the conical ring and the arch, the particles can be disturbed during gas flow, realizing the self-cleaning of the arch, the side wall of the conical ring and the channel, thereby improving the stability and efficiency of the dry distillation process.

[0015] 2. In this invention, the deformed sidewall of the bent ring will guide the rising gas towards the inner wall of the conical ring, allowing more gas to push the sidewall of the conical ring further under the guidance of the bent ring sidewall. This enables the conical ring to slide upward under the push of sufficient gas and maintain a stable position. In this way, it can reduce the unstable shaking and swaying of the conical ring caused by the difference in gas velocity between the inner and outer sides during gas flow, maintain the stability of the gas flow field, and improve the upward flow intensity of the gas.

[0016] 3. The present invention, through the rotation of the curved plate and the shaking of the rectangular plate, can cause shaking and disturbance between the two gases, thereby enabling the gas to flow upward while reducing the mutual interference between the two gases, which would cause the gas to diffuse between the conical ring and the arch, resulting in increased gas flow resistance between the conical ring and the arch. This further enhances the anti-blocking effect and improves the heat stability during the dry distillation process, thereby increasing the thermal efficiency of the dry distillation.

[0017] 4. In this invention, when the curved plate is pushed and rotated by the backflow gas, the rotating curved plate will guide the gas injected through the circular hole under its own curvature, so that the gas can flow upward stably and continuously. This can reduce the situation where the gas carries dust particles to re-attach and accumulate between the conical ring and the arch due to the backflow of gas, thereby further improving the uniformity of gas flow and improving the dry distillation efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 As shown, the present invention is a dual-channel anti-clogging structure for a Fushun-type dry distillation furnace, comprising a main body 1, a gas collection umbrella 101 fixedly connected to the top of the main body 1, a shell 4 sleeved on the outer surface of the main body 1, and a feed pipe fixedly connected to the top of the main body 1, and further comprising: Auxiliary mechanism 2 is installed inside the main body 1 to prevent the flow of flue gas from causing blockage of the channels during the dry distillation of materials; The swing mechanism 3 is installed on the side wall of the auxiliary mechanism 2 to prevent backflow of flue gas when the auxiliary mechanism 2 is working.

[0024] A gas supply pipe 102 is fixedly connected to the outer surface of the main body 1. The end of the gas supply pipe 102 away from the main body 1 extends through to the outside of the housing 4. The main body 1 includes: Ash removal assembly 11 is installed inside the main body 1 and is used to remove ash during the dry distillation process.

[0025] Auxiliary mechanism 2 includes an arch 201 fixedly connected inside the main body 1, and auxiliary mechanism 2 also includes: The sliding component 21 is installed inside the arch platform 201 and is used to form a shear flow of flue gas during the dry distillation process, thereby achieving the purpose of self-cleaning. Connecting component 22 is installed on top of sliding component 21.

[0026] The swing mechanism 3 includes an annular frame 301 disposed on the side wall of the connecting assembly 22, and the swing mechanism 3 also includes: Deformation component 31 is installed on the outer surface of the annular frame 301 and is used to guide the rising flue gas. The movable component 32 is installed on the side wall of the deformation component 31 to reduce the backflow of flue gas.

[0027] The main body 1 includes an ash dish 112 rotatably connected to the bottom of the main body 1, a base plate 111 fixedly connected to the bottom of the ash dish 112, and an air outlet pipe 113 fixedly connected to the middle of the base plate 111. A geared disc is fixedly connected to the bottom of the chassis 111. A motor 114 is installed on the outer surface of the geared disc. The output end of the motor 114 is meshed with the geared disc. First, the conveying end of the external hot gas conveying equipment is rotatably connected to the air outlet pipe 113 through a pipe. At the same time, the gas supply pipe 102 is connected to the gas generating conveying equipment. The chassis 111 is then installed on the ground through a support frame, and the motor 114 is also installed on the ground.

[0028] The side wall of the arch platform 201 has several oblique holes, and a fixing ring is fixedly connected inside the arch platform 201. The sliding assembly 21 includes two telescopic rods 211 fixedly connected to the inner wall of the arch 201. A conical ring 212 is fixedly connected to one end of the two telescopic rods 211 away from the arch 201. The outer surface of the conical ring 212 has several circular holes. When the gas flows upward, the gas flow will first contact the inner wall of the conical ring 212. Since the inner wall of the conical ring 212 has several circular grooves, when the gas flows upward, it will push the conical ring 212 to slide upward through the circular grooves.

[0029] The bottom of the conical ring 212 is fixedly connected with several sliding frames 214, the top of the conical ring 212 is fixedly connected with four bending plates 213, and the inner wall of the conical ring 212 is provided with several annular grooves. Among them, the sidewalls of several bending plates 213 are in contact with the fixed ring. When the conical ring 212 slides upward, it will drive the four bending plates 213 to slide synchronously. When the bending plates 213 slide, they will be blocked by the fixed ring and deform towards the center of the conical ring 212. When multiple bending plates 213 are bent and deformed, the flow channel at the center of the conical ring 212 can be reduced and the flow speed of gas through this channel can be accelerated.

[0030] The connecting assembly 22 includes a connecting ring 221 rotatably connected between four bent plates 213, and a telescopic frame 222 is fixedly connected inside the connecting ring 221; The bottom of the telescopic frame 222 is fixedly connected to a limiting plate 223, which is fixedly connected to the inner wall of the conical ring 212. When multiple bending plates 213 are bent and deformed under the push of the fixed ring, the deformation of the multiple bending plates 213 will drive the telescopic frame 222 to retract through the connecting ring 221. When the telescopic frame 222 retracts, it will drive the ring frame 301 to slide downward.

[0031] The ring frame 301 is fixedly connected to the bottom outer wall of the connecting ring 221; Deformation component 31 includes a limiting frame 312 that is slidably connected inside the sliding frame 214, and a bending ring 311 is fixedly connected to one end of the limiting frame 312 away from the sliding frame 214. The side wall of the bending ring 311 is in contact with the outer surface of the ring frame 301. Several rectangular plates 313 are fixedly connected to the side of the bending ring 311 away from the limiting frame 312. Several holes are opened on the side wall of the rectangular plates 313. When the ring frame 301 slides down, it will push the side wall of the bending ring 311 so that it slides down in the sliding frame 214 through the limiting frame 312. At the same time, when the side wall of the bending ring 311 is pushed by the ring frame 301, the bending ring 311 will bend and deform.

[0032] The active component 32 includes a C-shaped frame fixedly connected to the side wall of the rectangular plate 313. A curved plate 321 is rotatably connected inside the C-shaped frame. The side wall of the curved plate 321 has several holes. Two limiting springs 322 are fixedly connected to the side of the curved plate 321 near the rectangular plate 313, and the ends of the two limiting springs 322 away from the curved plate 321 are fixedly connected to the side wall of the rectangular plate 313. An auxiliary spring 323 is fixedly connected to the side wall of the C-shaped frame. The side of the auxiliary spring 323 away from the C-shaped frame is fixedly connected to the side wall of the conical ring 212. By rotating the bending plate 321 and shaking the rectangular plate 313, the two gases can be shaken and disturbed, thereby enabling the gas to flow upward while reducing the mutual interference between the two gases, which causes the gas to diffuse between the conical ring 212 and the arch 201.

[0033] In use, the conveying end of the external thermal gas conveying equipment is first connected to the air outlet pipe 113 via a pipe, and the gas supply pipe 102 is connected to the gas generating conveying equipment. The chassis 111 is installed on the ground via a support frame, and the motor 114 is also installed on the ground. When dry distillation is required, the motor 114 is started and the workers convey the oil shale into the interior of the main body 1 through the feed pipe. At the same time, the generating gas and thermal gas are conveyed into the main body 1. At this time, the thermal gas and generating gas will mix at the bottom of the arch platform 201 and flow upward. At this time, the oil shale will be cracked by the heat of the hot circulating gas inside the main body 1 and produce methane, olefins and tar. The resulting mixed gas is then collected by the gas collection umbrella 101 and sent out. At the same time, the motor 114 will drive the ash pan 112 to rotate when it is working. After the dry distillation is completed, the ash residue is discharged by the ash discharge component 11, thus completing the purpose of dry distillation of the material.

[0034] When the gas flows upward, it first contacts the inner wall of the conical ring 212. Since the inner wall of the conical ring 212 has several annular grooves, the upward flow of gas pushes the conical ring 212 upward through these grooves. At this time, the distance between the top area of ​​the conical ring 212 and the arch 201 decreases. Most of the gas then flows upward through the center of the conical ring 212, while some flows upward through the channel between the conical ring 212 and the arch 201. Simultaneously, some gas is ejected towards the arch 201 through several circular holes on the conical ring 212. At the same time, the gas supplied by the gas delivery pipe 102 is ejected towards the conical ring 212 through oblique holes on the arch 201. The gas ejected through the oblique holes and circular holes then interacts with the conical ring 212. The airflow shear force generated between the two can prevent shale particles from accumulating on the sidewalls of the arch 201 and the conical ring 212. At the same time, when the conical ring 212 slides upward, it will drive the four bending plates 213 to slide synchronously. When the bending plates 213 slide, they will bend towards the center of the conical ring 212 due to the obstruction of the fixed ring. When multiple bending plates 213 bend and deform, the flow channel in the center of the conical ring 212 can be reduced and the flow speed of gas through this channel can be accelerated. At the same time, through the flow pressure difference of gas through the middle of the conical ring 212 and the channel between the conical ring 212 and the arch 201, the particles can be disturbed during gas flow, realizing the self-cleaning of the arch 201, the sidewalls of the conical ring 212 and the channel, thereby improving the stability and efficiency of the dry distillation process.

[0035] When multiple bending plates 213 bend and deform under the push of the fixed ring, the deformation of the multiple bending plates 213 will drive the telescopic frame 222 to retract through the connecting ring 221. When the telescopic frame 222 retracts, it will drive the ring frame 301 to slide downward. When the ring frame 301 slides downward, it will push the side wall of the bending ring 311 so that it slides downward within the sliding frame 214 through the limiting frame 312. At the same time, when the side wall of the bending ring 311 is pushed by the ring frame 301, the bending ring 311 will bend and deform. At this time, the bent ring 311 after deformation The sidewall then guides the rising gas towards the inner wall of the conical ring 212, allowing more gas to push the sidewall of the conical ring 212 further under the guidance of the sidewall of the bent ring 311. This enables the conical ring 212 to slide upwards under sufficient gas pressure and maintain a stable position. Consequently, it reduces the unstable swaying and shaking of the conical ring 212 caused by the velocity difference between the inner and outer sides of the gas during gas flow, thus maintaining a stable gas flow field while increasing the upward flow intensity of the gas.

[0036] When the bending ring 311 slides and deforms under the push of the ring frame 301, the sliding of the bending ring 311 will cause multiple rectangular plates 313 to slide synchronously. When the rectangular plates 313 slide, they will squeeze the auxiliary spring 323 through the C-shaped frame and move closer to the conical ring 212. After being compressed, the auxiliary spring 323 will accumulate elastic potential energy. Then, when the gas is ejected through the round hole on the conical ring 212 and the oblique hole on the arch 201, the two jets of gas will act on the sidewalls of the rectangular plate 313 and the bending plate 321, causing the rectangular plate 313 to sway back and forth under the elasticity of the auxiliary spring 323. At the same time, after passing through the conical ring 212, the auxiliary spring 313 will move back and forth under the elasticity of the auxiliary spring 323. The gas ejected from the circular hole on the conical ring 212 acts on the surface of the curved plate 321, causing the curved plate 321 to rotate back and forth within the C-shaped frame. The rotation of the curved plate 321 and the swaying of the rectangular plate 313 create swaying and disturbance between the two gas streams. This allows the gas to flow upward while reducing mutual interference between the two gas streams, which would otherwise cause the gas to diffuse between the conical ring 212 and the arch 201, thus increasing the gas flow resistance between the conical ring 212 and the arch 201. This further enhances the anti-clogging effect and improves the heat stability and thermal efficiency during the dry distillation process.

[0037] When the conical ring 212 slides upward to reduce the distance between the top of the conical ring 212 and the arch 201, the rectangular plate 313 will move closer to the conical ring 212 under the pull of the bending ring 311. Since the end of the bent plate 321 away from the bending ring 311 forms a conical opening with the rectangular plate 313, when the gas between the conical ring 212 and the arch 201 flows upward, the gas is prone to collide with the side wall of the arch 201 due to the reduction in the channel spacing and flow back. When the gas flows back, the backflowing gas will enter the opening between the rectangular plate 313 and the bent plate 321 and push the arch 201. The curved plate 321 rotates, and when the curved plate 321 rotates, it forms an angle between the rectangular plate 313 and the limiting frame 312, guiding the returning gas back. At the same time, when the curved plate 321 is pushed by the returning gas to rotate, the rotating curved plate 321 guides the gas injected through the circular hole under its own curvature, so that the gas can flow upward stably and continuously. This reduces the situation where the gas carries dust particles to re-attach and accumulate between the conical ring 212 and the arch 201 due to the gas backflow, thereby further improving the uniformity of gas flow and improving the dry distillation efficiency.
