Description

Technical Field

[0001] The invention relates to the technical field of flue gas treatment, in particular to a machine-made charcoal flue gas treatment device with waste heat utilization. Background Art

[0002] The charcoal production process primarily involves three key steps: drying the biomass feedstock, forming rods, and high-temperature carbonization. During the carbonization stage, the feedstock undergoes pyrolysis in anoxic conditions to produce charcoal, generating a flue gas mixture containing pollutants such as tar, particulate matter, carbon monoxide, sulfides, and polycyclic aromatic hydrocarbons. Discharging this flue gas untreated not only pollutes the air, threatening the surrounding ecosystem and the health of residents, but also poses legal risks for violating environmental regulations. Therefore, efficient purification of charcoal flue gas (hereafter referred to as flue gas) is essential for achieving clean production and reducing carbon emissions.

[0003] The most commonly used method of existing flue gas treatment is to treat the flue gas through a spray tower. The process of flue gas treatment in a spray tower is usually carried out using cross-distributed spray pipes and nozzles arranged on the spray pipes.

DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0030] See Figure 1-Figure 2 A machine-made charcoal flue gas treatment device with waste heat utilization includes a smoke treatment tank 1, which is divided into three layers: upper, middle and lower layers by two upper and lower partition plates 11 fixedly connected to the smoke treatment tank 1. The smoke treatment tank 1 is provided with an air inlet 12 and a water outlet 13 on the left and right sides of the lower layer respectively. The upper and middle layers of the smoke treatment tank 1 are jointly provided with a spray part 2. The top of the smoke treatment tank 1 is connected to an outlet pipe 15 through a conical guide ring 14. A heat exchange component 3 is provided on the side of the conical guide ring 14. A demisting unit 4 is provided between the conical guide ring 14 and the outlet pipe 15.

[0031] The spraying part 2 is fixedly installed on the upper part of the upper and middle layers using existing cross pipes and multiple vertical nozzles. The spraying part 2 transports the spray liquid through the water pipe 21; multiple through holes are evenly arranged on the partition plate 11, and multiple spherical piles are stacked on each partition plate 11. The spherical piles are made of ceramic material, and the diameter of the through holes is smaller than the diameter of the spherical piles.

[0032] The present invention uses the spraying element 2 to spray the flue gas input from the air inlet 12, thereby eliminating some harmful components in the flue gas through a comprehensive physical and chemical reaction between the spray liquid and the flue gas, and prolongs the reaction time between the flue gas and the spray liquid through the spherical pile, thereby ensuring the effect of the spray liquid in eliminating harmful components in the flue gas. At the same time, the excess heat in the flue gas after spraying is utilized for heat exchange through the heat exchange component 3, and the water mist generated in the flue gas after spraying can be effectively eliminated through the demisting unit 4, thereby ensuring the normal operation of subsequent processing equipment.

[0033] Specifically, first, the air outlet pipe 15, the water outlet 13 and the water pipe 21 are connected to the connecting pipe, the liquid processing equipment and the spray liquid containing structure respectively, wherein the spray liquid is transported to the water pipe 21 by an external water pump, and then the air inlet 12 is connected to the external smoke transmission channel. After all the pipes are connected, the smoke is continuously introduced from the air inlet 12. As the smoke is introduced, the smoke moves upward in sequence through the through holes on the partition plate 11. At this time, the spray part 2 is controlled to continuously output the spray liquid. As the spray liquid falls, the spray The liquid will continue to react physically and chemically with the flue gas. At the same time, due to the presence of the spherical pile, the spray liquid can react with the flue gas more fully. After the flue gas passes through the double-layer spray, the heat exchange component 3 will replace the residual heat in the flue gas, thereby reusing this part of the heat. After the flue gas is heat exchanged and cooled, it will move to the position of the demisting unit 4, and the flue gas will be effectively removed by the demisting unit 4, and the demisted flue gas will be discharged through the outlet pipe 15, which is convenient for subsequent treatment of the flue gas.

[0034] Continue reading Figure 1-Figure 2 An L-shaped air duct 121 is fixed to one end of the air inlet 12 located inside the smoke treatment tank 1. The end of the L-shaped air duct 121, which is away from the wall of the smoke treatment tank 1, faces the bottom of the smoke treatment tank 1. The L-shaped air duct 121 prevents the air inlet 12 from dripping spray liquid from above, thereby ensuring the normal operation of the smoke transport pipeline.

[0035] See Figure 2-Figure 3 The heat exchange component 3 includes a plurality of connecting plates 31 uniformly fixed on the inner side of the conical guide ring 14 in the circumferential direction. The connecting plates 31 are spiral-shaped, and a connecting block 311 is fixed between all the connecting plates 31. An annular sealing sleeve 312 is provided on the outer side of the conical guide ring 14. The sealing sleeve 312 is hollow. An input port 313 and an output port 314 are respectively installed on the left and right sides of the sealing sleeve 312. Circulating water is introduced into the sealing sleeve 312.

[0036] The heat exchange component 3 is used to convert and utilize the waste heat of the flue gas, convert the waste heat of the flue gas through circulating water, and perform subsequent energy conversion through the circulating water with waste heat, so as to reuse this part of the heat, and further cool the flue gas after spraying through the conical guide ring 14 and circulating water, ensuring that the subsequent demisting unit 4 continues to perform demisting stably, and increases the rising distance of the flue gas through the conical guide ring 14 in conjunction with the connecting plate 31, thereby slowing down the rising speed of the flue gas, thereby allowing the flue gas and circulating water to fully convert heat.

[0037] Specifically, after the flue gas passes through the double-layer spray and moves to the position of the heat exchange component 3, circulating water is slowly introduced from the input port 313. At this time, the flue gas spirals upward under the guidance of the connecting plate 31. During the spiral upward movement of the flue gas, the circulating water introduced into the closed sleeve 312 will continuously conduct heat with the flue gas with higher temperature while slowly moving toward the output port 314, thereby rapidly cooling the flue gas.

[0038] It should be noted that, in order to ensure the heat conduction effect between the circulating water and the flue gas, the conical guide ring 14 needs to be made of a material with good thermal conductivity.

[0039] See Figure 4-Figure 6 The defogger unit 4 includes a mounting plate 41 fixed to the side of the conical guide ring 14, a motor 411 is installed on the top of the mounting plate 41 through a motor seat, a guide component 42 is connected between the output end of the motor 411 and the air outlet pipe 15, and a plurality of groups of movable defoggers 43 staggered in upper and lower positions are provided in the air outlet pipe 15. Each group of movable defoggers 43 can be driven by the guide component 42 and complete the defogger, and a fixed defogger 44 is provided at the top of the air outlet pipe 15.

[0040] A cross fixing plate 151 is fixed at the bottom position in the air outlet pipe 15, a mounting column 152 is fixed on the top of the cross fixing plate 151, and multiple sections of spiral guide plates 153 spiraling upward are installed on the side of the mounting column 152. The spiral guide plates 153 are staggered in the upper and lower positions of the movable defogger 43, and two fixing rings 154 distributed upper and lower are fixed on the side of the mounting column 152 corresponding to the movable defogger 43.

[0041] The flue gas is guided by the spiral guide plate 153, and the mist in the flue gas is continuously removed by the demisting unit 4 during the guiding process. The spiral guide plate 153 itself can have a certain blocking effect on the mist during the contact with the flue gas. After the mist condenses into droplets on the spiral guide plate 153, it can directly fall downward from the spiral guide plate 153 until it gradually flows downward through the air outlet pipe 15, the conical guide ring 14 and the inner wall of the smoke treatment tank 1, and falls to the bottom of the smoke treatment tank 1, which can prevent the droplets from falling directly and returning to the flue gas.

[0042] Continue reading Figure 4-Figure 7 The guide component 42 includes a driving gear 421 fixed to the output end of the motor 411, and a positioning ring plate 422 is symmetrically fixed to the upper and lower sides of the air outlet pipe 15. A transmission sleeve 423 is installed on the two positioning ring plates 422 to rotate together. A plurality of tooth-shaped protrusions 424 that mesh with the driving gear 421 are evenly fixed on the side of the transmission sleeve 423 corresponding to the position of the driving gear 421. The inner wall of the transmission sleeve 423 is provided with a track structure for guiding the mobile demisting unit 43; the track structure includes a rotating ring 425 fixed to the inner side wall of the transmission sleeve 423, and a guide groove 426 is opened on the rotating ring 425. A linkage rod 427 that cooperates with the guide groove 426 is installed on the mobile demisting unit 43. The guide groove 426 cooperates with the linkage rod 427 to enable the mobile demisting unit 43 to move and intercept the mist in the flue gas.

[0043] The guide groove 426 is composed of a plurality of circumferentially evenly arranged bending segments, and every two bending segments are connected by an arc segment. The number of bending segments is an even number, ensuring that the movable demisting parts 43 at the same height can demist at the same time.

[0044] In order to ensure that the rotating ring 425 rotates synchronously as a whole, a plurality of U-shaped connecting rods are used on the rotating ring 425 to stably connect the two parts of the rotating ring 425 separated by the guide groove 426.

[0045] The staggered mobile defoggers 43 cooperate with the spiral guide plates 153 that slow down and guide the rise of the flue gas to ensure that the defogger unit 4 can completely and effectively remove the mist in the flue gas. At the same time, the guide components 42 drive the staggered mobile defoggers 43 to perform defogger. The self-cleaning of the mobile defogger 43 can also be completed through the guide components 42. At the same time, the fixed defogger 44 and the mobile defogger 43 are combined to defog the flue gas. This method ensures that the mist in the flue gas is completely and effectively removed by combining dynamic defogger and static defogger.

[0046] Specifically, when the flue gas continues to move upward from the position of the heat exchange component 3, the flue gas will move upward in a spiral due to the spiral guiding action of the spiral guide plate 153, and the control motor 411 will drive the driving gear 421 to rotate. The driving gear 421 will drive the transmission sleeve 423 to rotate through the tooth-shaped protrusion 424. When the transmission sleeve 423 rotates, the rotating ring 425 rotates together with the transmission sleeve 423 and drives the linkage rod 427 and the mobile defogger 43 to move toward the position of the fixed ring 154 through the guide groove 426. During the movement of the mobile defogger 43, the mobile defogger 43 will complete the interception of the mist in the flue gas, thereby allowing this part of the mist to separate from the flue gas.

[0047] See Figure 5-Figure 8The mobile defogger 43 includes a slide groove 431 opened on the side of the air outlet pipe 15. The bottom of the slide groove 431 is horizontally slidably connected to a sliding block 432. The side of the sliding block 432 close to the axis of the air outlet pipe 15 is an arc-shaped surface. The arc-shaped surface of the sliding block 432 is provided with a sponge block 433. The sponge block 433 is made of activated carbon fiber material. The upper part of the slide groove 431 is provided with a self-cleaning structure for cleaning the moisture in the sponge block 433.

[0048] The self-cleaning structure includes a vertical groove 434 opened on the side wall of the air outlet pipe 15 and connected to the slide groove 431. An arc-shaped connecting plate 435 is connected to the vertical groove 434 through a compression spring. A right-angled dewatering plate 436 is fixed to the bottom of the arc-shaped connecting plate 435. The right-angled dewatering plate 436 corresponds to a section of the sponge block 433, which is an arc-shaped plate. The arc-shaped plate is pressed against the side of the sponge block 433 close to the fixed ring 154. A transmission structure is arranged between the right-angled dewatering plate 436, the sliding block 432 and the guide component 42.

[0049] The transmission structure includes a horizontal groove 437 opened on the top of the sliding block 432, and the upper limit sliding connection of the horizontal groove 437 is connected to the transmission block 438. The relative positions of the transmission block 438 and the right-angle dewatering plate 436 are both provided with matching inclined surfaces, and the top of the transmission block 438 is fixedly connected to the linkage rod 427.

[0050] The transmission block 438 is guided by the guide component 42 to drive the right-angled water-removing plate 436 and the sliding block 432 to move in turn, which not only drives the right-angled water-removing plate 436 to complete the cleaning action of the sponge block 433, but also enables the sliding block 432 to complete the action of moving to and returning to the position of the fixed ring 154. The transmission block 438 and the right-angled water-removing plate 436 are pushed by the inclined surface so that the air outlet pipe 15 can always be closed when the two are in contact.

[0051] Specifically, when the transmission sleeve 423 rotates, the rotating ring 425 rotates with the transmission sleeve 423. At this time, the bent section on the guide groove 426 drives the linkage rod 427 and the transmission block 438 to move toward the position of the fixed ring 154. The transmission block 438 first pushes the right-angled dewatering plate 436 upward through the coordinated inclined surface, and the right-angled dewatering plate 436 and the transmission block 438 are located in the slide groove 431. When the right-angled dewatering plate 436 is close to the sponge block 433 and moves upward to a position higher than After the sliding block 432, the transmission block 438 also moves to the horizontal groove 437 close to the side of the fixed ring 154. As the transmission block 438 continues to move, the transmission block 438 will change from pushing the right-angled dewatering plate 436 upward to pushing the sliding block 432 toward the position of the fixed ring 154. As the sliding block 432 continues to move, the sponge block 433 will move synchronously and block and capture the mist in the upward-moving flue gas along the way until the sponge block 433 moves to fit the fixed ring 154.

[0052] Then the transmission block 438 will return to its original position due to the outward pushing of the linkage rod 427 by the bending section of the guide groove 426. During this process, the transmission block 438 will first drive the sliding block 432 to return to its original position, and then disengage from the upward push on the right-angled dewatering plate 436, so that the right-angled dewatering plate 436 moves downward under its own gravity and the action of the compressed spring and automatically removes the water accumulated in the sponge block 433 through the arc plate. At this time, the removed water will move downward along the air outlet pipe 15 to the bottom of the smoke treatment tank 1.

[0053] See Figure 6-Figure 9 The fixed demisting part 44 includes an obstructing oblique block 441 symmetrically fixed to the top of the outlet pipe 15 in the front and back directions. An oblique moving block 442 is obliquely slidably connected to the inclined surface of each obstructing oblique block 441. Elastic retractable scrapers 443 are symmetrically arranged on the left and right sides of the oblique moving block 442. A connecting rod 444 is hinged between the oblique moving block 442 and the top of the upper and similarly positioned right-angled dewatering plate 436; guide slopes are symmetrically arranged on the front and back sides of the oblique moving block 442.

[0054] The fixed demisting part 44 is used to further block and remove the mist in the continuously rising flue gas, thereby ensuring the effect of removing the mist in the flue gas. At the same time, the telescopic scraper 443 moves back and forth along the inclined surface of the blocking bevel 441 under the cooperation of the connecting rod 444 and the right-angle dewatering plate 436, thereby pushing the droplets condensed from the mist blocked by the side of the blocking bevel 441, so that these water droplets are separated from the blocking bevel 441 and move downward along the exhaust pipe 15.

[0055] Specifically, when the smoke moves to the top position in the exhaust duct 15, the blocking oblique block 441 will block the smoke. At this time, the blocking oblique block 441 will intercept the mist in the smoke again. As the uppermost right-angled dewatering plate 436 moves up and down, the connecting rod 444 will drive the oblique moving block 442 to move up and down synchronously. In the process of the oblique moving block 442 moving upward, the telescopic scraper 443 will move along the blocking oblique block 441 to remove the droplets condensed by the mist. The mist is shoveled and falls from the left and right sides along the guide slope. When the oblique moving block 442 moves upward, the telescopic scraper 443 will shovel the droplets condensed from the mist along the blocking oblique block 441 and make the droplets fall from the left and right sides along the guide slope. When the oblique moving block 442 moves downward, the telescopic scraper 443 will shovel the droplets condensed from the mist along the blocking oblique block 441 and make the droplets move downward from the inner wall of the outlet pipe 15 along the guide slope.

[0056] The present invention operates as follows: First, connect the air outlet pipe 15, water outlet 13, and water delivery pipe 21 to the connecting pipe, liquid processing equipment, and spray liquid storage structure, respectively. Then, connect the air inlet 12 to the external flue gas transmission channel. Once all pipes are connected, flue gas is continuously introduced through the air inlet 12, and the flue gas sequentially moves upward through the through-holes in the partition plate 11. At this time, the spray element 2 is controlled to continuously output the spray liquid, which reacts physically and chemically with the flue gas. The presence of the spherical pile facilitates the reaction.

[0057] In the second step, the flue gas moves to the position of the heat exchange component 3 after passing through the double-layer spray. Circulating water is first introduced from the input port 313. The flue gas moves upward in a spiral under the guidance of the connecting plate 31. The circulating water in the closed sleeve 312 quickly cools the flue gas through heat conduction, and the absorbed heat is converted into other forms of energy.

[0058] In the third step, the flue gas after cooling continues to move upward and spirally rises under the action of the spiral guide plate 153. Then the motor 411 is controlled to drive the driving gear 421 to rotate, and the transmission sleeve 423 is driven to rotate through the toothed protrusion 424, thereby driving the rotating ring 425 to rotate synchronously. The rotating ring 425 drives the linkage rod 427 and the transmission block 438 to move toward the fixed ring 154 through the guide groove 426. In the process of the linkage rod 427 driving the transmission block 438 to move, the transmission block 438 pushes the right-angle dewatering plate 436 upward through the coordinated inclined surface until the right-angle dewatering plate 436 is higher than the sliding block 432, and then the transmission block 438 changes to push the sliding block 432.

[0059] In the fourth step, when the sliding block 432 is pushed by the transmission block 438, the sponge block 433 will intercept and capture the mist in the smoke. When the transmission block 438 is again driven by the linkage rod 427 and the guide groove 426 and returns to its original position, it first drives the sliding block 432 to reset, and then releases the support for the right-angle dewatering plate 436. Then, the right-angle dewatering plate 436 will descend under the action of gravity and the spring, squeezing the sponge block 433 through the curved plate to release moisture. The squeezed moisture condenses into droplets and flows back to the bottom of the smoke treatment tank 1 along the outlet pipe 15. When the smoke moves to the top of the outlet pipe 15, the blocking oblique block 441 will intercept the mist in the smoke for a second time. When the uppermost right-angle dewatering plate 436 moves up and down, it drives the oblique moving block 442 to move synchronously through the connecting rod 444. When the oblique moving block 442 moves upward, the telescopic scraper 443 shovels the droplets along the blocking oblique block 441, causing them to fall to both sides along the guide slope; when moving downward, the telescopic scraper 443 shovels the droplets downward and causes the droplets to slide along the inner wall of the outlet pipe.

[0060] In the fifth step, the demisted flue gas is output through the outlet pipe 15, the residual heat is recycled through the heat exchange component 3, and the spray liquid returns to the liquid treatment equipment through the water outlet 13 for regeneration, forming a complete flue gas treatment circulation system.

[0061] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
