Description

[0002] The existing Chinese patent (CN207680299U) discloses a flue gas treatment device. On the one hand, this device can retain the substances in the flue gas in the liquid to purify the flue gas. On the other hand, it can collect the liquid to prevent the wood vinegar liquid from being discharged with the flue gas and polluting the environment. Moreover, the liquid circulation can also flush the flue gas collection pipeline to prevent blockage of the flue gas collection pipeline. However, since the liquid only flows along the lower part of the pipeline and flushes the lower part of the pipeline, it cannot flush the upper part of the pipeline, resulting in attachments remaining on the inner wall of the pipeline. It is necessary to manually suspend the use of the carbonization furnace, disassemble the pipeline, and perform manual cleaning.

[0022] In order to facilitate the flow of liquid, each cooling pipe 2 is inclined with the left end higher than the right end.

[0023] The water spraying assembly located in the front includes a fixed block 101, an annular pipe 102, an atomizer 103, and a water inlet pipe 104; four fixed blocks 101 are fixedly connected to the front cooling pipe 2; an annular pipe 102 is fixedly connected to the four fixed blocks 101 together; two atomizers 103 distributed in an annular array are connected to the inside of the annular pipe 102; the nozzles of the two atomizers 103 are embedded in the front cooling pipe 2; a water inlet pipe 104 is connected to the annular pipe 102.

[0024] The rotating assembly located in the front includes a fixed plate 201, a motor 202, a spur gear 203, an annular plate 204, and a toothed ring 205; the hollow sphere 8 is assembled by two semi - spheres detachably; the inner wall of the front hollow sphere 8 is fixedly connected with the fixed plate 201; the motor 202 is bolt - connected to the fixed plate 201; the output shaft of the motor 202 is fixedly connected with the spur gear 203; the front hollow sphere 8 is rotatably connected with the annular plate 204; the outer ring surface of the annular plate 204 is fixedly connected with the scraping strip 9; the inner ring surface of the annular plate 204 is fixedly connected with the toothed ring 205; the spur gear 203 meshes with the toothed ring 205.

[0025] In order to facilitate the scraping of attachments, the left part of each scraping strip 9 is serrated.

[0026] It also includes a drain pipe 301, a first round pipe 302, a fan 303, and a second round pipe 304; the lower part of the tank body 3 is connected to the drain pipe 301; the upper part of the tank body 3 is connected to the first round pipe 302; the first round pipe 302 is connected to the fan 303; the output end of the fan 303 is connected to the second round pipe 304.

[0027] In order to provide energy for the motor 202, a detachable power source is arranged inside the hollow sphere 8.

[0028] The working steps of this embodiment are as follows: The rotation described below, the viewing direction is from front to back, from top to bottom, and from right to left; The first step, when in use, first place the flue gas treatment equipment of this easy - to - maintain carbonization furnace at the required position; Second step, the operator externally connects a power supply to all components that require electric drive. The lower end of the T-shaped pipe 1 is communicated with the exhaust port of the carbonization furnace. Water pipes are externally connected to the two water inlet pipes 104, a refiner is externally connected to the drain pipe 301, and the second round pipe 304 is communicated with the combustion chamber of the carbonization furnace. Since when the existing flue gas treatment equipment cleans the pipeline through liquid, the liquid only flushes the lower part of the pipeline and cannot flush the upper part of the pipeline, attachments will remain on the inner wall of the pipeline. After long-term use, it is necessary to manually suspend the use of the carbonization furnace, disassemble the pipeline for manual cleaning. This not only takes a long time and has low cleaning efficiency, but also affects the production efficiency of the carbonization furnace. Therefore, after the carbonization furnace starts running, the flue gas discharged from the carbonization furnace will enter the T-shaped pipe 1. At this time, control the two electric valves in the T-shaped pipe 1 to open, so that the flue gas enters the two cooling pipes 2. At the same time, control the two water spraying assemblies to run synchronously. Taking the front water spraying assembly as an example, control the externally connected water pipe to transport cold water into the water inlet pipe 104. The cold water enters the annular pipe 102 and the atomizer 103, and then continuously sprays water mist through the nozzles of the two atomizers 103 to cool the high-temperature flue gas. And under the action of the water mist, the wood tar and carbon particles contained in the high-temperature flue gas will mix with water molecules and gradually sink in the cooling pipe 2 to form wood vinegar liquid. Then the wood vinegar liquid flows along the inclined cooling pipe 2 into the limit cover 4, and then flows from the limit cover 4 into the tank body 3, and then is transported to the externally connected refiner through the drain pipe 301 for oil refining to separate the wood tar in the wood vinegar liquid; Meanwhile, since the wood gas will not fuse with water, after the wood gas in the cooling pipe 2 passes through the limit cover 4, it will come to the tank body 3. Then control the fan 303 to start, and pump the wood gas in the tank body 3 into the fan 303 through the first round pipe 302, and transport it to the combustion chamber through the output end of the fan 303 and the second round pipe 304 for secondary combustion, achieving sustainable utilization of resources, reducing fuel consumption, and at the same time, avoiding the pollution of the environment caused by the emission of wood gas into the air.

[0029] In the third step, after the carbonization furnace has been operating for some time and it is necessary to maintain and clean the attachments inside the front cooling pipe 2, the operator controls the electric valve at the front of the T-shaped pipe 1 to close, the two atomizers 103 stop spraying water mist, removes the end cover 2001 of the front cooling pipe 2, and then controls the telescopic part of the front electric push rod 6 to push out, driving the front cooling pipe 2, the front water spraying assembly, the baffle 5, the slider 7, the hollow sphere 8, the scraping strip 9 and the rotating assembly to rotate around the T-shaped pipe 1 as the center. The front cooling pipe 2 slides in the corresponding arc-shaped chute 4001, and the baffle 5 slides on the limit cover 4 until the front cooling pipe 2 rotates to the uppermost end of the arc-shaped chute 4001. At this time, the front cooling pipe 2 is in an inclined state with the left end lower and the right end higher. Under the gravity of the hollow sphere 8, the slider 7 moves leftward along the trajectory of the linear chute 2002, driving the hollow sphere 8, the scraping strip 9 and the rotating assembly to move leftward together, and scraping the attachments on the inner wall of the front cooling pipe 2 through the scraping strip 9. The attachments scraped off by the scraping strip 9, as the hollow sphere 8 moves to the leftmost end of the front cooling pipe 2, are discharged from the leftmost end of the front cooling pipe 2, preventing a large amount of attachments from accumulating in the front cooling pipe 2 and affecting the normal flow of flue gas; During the movement of the hollow sphere 8 inside the cooling pipe 2, the nozzles of the two atomizers 103 can also be scraped through the scraping strip 9 to scrape off the stains on the nozzles of the two atomizers 103, facilitating the normal use of the atomizers 103.

[0030] As the hollow sphere 8 continues to move, the attachments scraped off by the scraping strip 9 gradually increase. After the attachments accumulate to a certain extent, it is easy to block the hollow sphere 8 inside the cooling pipe 2 and prevent it from continuing to move to remove the attachments inside the cooling pipe 2. Therefore, the output shaft of the control motor 202 drives the spur gear 203 to rotate, and the spur gear 203 drives the scraping strip 9, the ring plate 204 and the toothed ring 205 to rotate together. Through the continuously rotating serrated scraping strip 9, the attachments accumulated on the moving path of the hollow sphere 8 are scattered, and the scattered attachments are discharged outward along the inclined cooling pipe 2, preventing too many accumulated attachments from intercepting the hollow sphere 8 and causing the hollow sphere 8 to be unable to continue cleaning the attachments.

[0031] During the operation of the carbonization furnace, one of the cooling pipes 2 can be controlled to close for cleaning work. In this way, the work of production and cleaning and maintenance can be achieved simultaneously, without reducing the output and working time of the carbonization furnace. Then, the cooling pipe 2 is pushed by the electric push rod 6 to rotate, changing the inclined state of the cooling pipe 2 from the left high and right low to the left low and right high. Under the gravity of the hollow sphere 8, the scraping strip 9 is driven to move leftward inside the cooling pipe 2 to scrape off the attachments inside the cooling pipe 2, and the rotating scraping strip 9 is controlled to scatter and remove the scraped attachments. In this way, there is no need to manually disassemble the pipeline for cleaning, saving a lot of time and improving the cleaning efficiency.

[0032] In the fourth step, after the front cooling pipe 2 is cleaned, the telescopic part of the front electric push rod 6 is controlled to contract, driving the connected parts to rotate, so that the front cooling pipe 2 returns to the state of higher on the left and lower on the right. At this time, the slider 7 moves to the right along the trajectory of the linear slide groove 2002 under the action of the gravity of the hollow sphere 8, driving the hollow sphere 8, the scraper 9 and the rotating assembly to move to the right together, returning to the rightmost end of the front cooling pipe 2, and then installing the end cover 2001 back on the front cooling pipe 2.

The end of the rope 403 passes through the filter frame 401; the inner side of the hollow ring 402 is fixedly connected to the filter cloth 404; the filter frame 401 is provided with a groove 40102; two round rods 405 are fixedly connected to the groove 40102; the two round rods 405 are slidably connected to a handle 406; a spring 2 407 is respectively provided at the connection between the two round rods 405 and the handle 406; the two ends of the rope 403 are fixedly connected to the handle 406; the handle 406 is fixedly connected to a limit rod 408; the filter frame 401 is slidably connected to a wedge block 409; a spring 3 410 is fixedly connected between the wedge block 409 and the filter frame 401.

[0034] To facilitate the operator to hold, two grip holes 40103 are provided on the filter frame 401 .

[0035] In order to facilitate the close contact between the limiting rod 408 and the wedge block 409 , a cut surface 40801 is formed on the limiting rod 408 .

[0036] The working principle of this embodiment is: In step 3 of embodiment 1: after the wood vinegar enters the tank body 3, it will flow down along the tank body 3. At this time, the carbon particles in the wood vinegar are filtered by the filter cloth 404 in the filter frame 401, and the carbon particles in the wood vinegar are filtered out, and the wood vinegar filtered by the filter cloth 404 continues to flow down to the bottom of the tank body 3, and is transported to the oil refinery through the drain pipe 301, so as to avoid a large amount of carbon particles entering the oil refinery together with the wood vinegar, causing blockage of the pipeline, filter and heat exchanger of the oil refinery, and causing the oil refinery to be unable to be used normally; After the filter cloth 404 has been working for a long time, the filtered carbon particles will accumulate on the filter cloth 404. When the operator removes the filter frame 401, some of the accumulated carbon particles will be scraped off by the tank body 3 and fall into the wood vinegar liquid below the tank body 3. Along with the wood vinegar liquid, it is transported to the oil refiner, causing damage to the oil refiner and shortening the service life of the oil refiner. Therefore, when a large amount of carbon particles accumulate on the filter cloth 404, affecting the normal filtration of the filter cloth 404, and it is necessary to remove the filter frame 401 from the tank body 3 to clean the filter cloth 404 inside the filter frame 401, control the telescopic parts of the two electric push rods 6 to push out, drive the connected components to rotate, and make the two cooling pipes 2 in a state where the left is low and the right is high, so that the wood vinegar liquid in the two cooling pipes 2 temporarily stops flowing into the tank body 3. Before the operator removes the filter frame 401, first manually grasp the handle 406 and move it outward on the two round rods 405. The handle 406 drives the rope 403 and the limiting rod 408 to move together, forcing the two second springs 407 to compress. When the rope 403 is pulled outward, it will force the rubber hollow ring 402 to compress towards the center. At the same time, it drives the filter cloth 404 to also contract, making the horizontally placed filter cloth 404 gradually concave downward; Meanwhile, during the movement of the limiting rod 408, it will contact the wedge-shaped block 409, forcing the wedge-shaped block 409 to move downward, and the third spring 410 is forced to stretch. After the wedge-shaped block 409 passes over the limiting rod 408 and contacts the section surface 40801 of the limiting rod 408, the operator releases the handle 406. Under the action of the two second springs 407, the handle 406 is restricted by the wedge-shaped block 409. At this time, the hollow ring 402 contacts the inner ring surface of the annular groove 40101, and the filter cloth 404 also changes from a horizontal state to a loose concave state. The carbon particles on the filter cloth 404 also fall into the filter frame 401 along with the downward depression of the filter cloth 404. Then the operator reaches into the two holding holes 40103, grabs the filter frame 401, and then removes the filter frame 401 from the tank body 3. At this time, because the carbon particles on the filter cloth 404 are all located inside the filter frame 401, the carbon particles on the filter cloth 404 will not be scraped back into the tank body 3, avoiding carbon particles from entering the oil refiner and causing damage to the oil refiner.

[0037] After the filter cloth 404 is cleaned, the operator puts the filter frame 401 back into the tank body 3, then grabs the wedge-shaped block 409 and moves it downward, forcing the third spring 410 to stretch, so that the wedge-shaped block 409 no longer restricts the limiting rod 408. Then the two second springs 407 automatically contract, driving the handle 406 and the rope 403 to reset. At the same time, the rubber hollow ring 402 expands and resets in the annular groove 40101 as the rope 403 is released, making the loose hollow ring 402 return to a horizontal state.
