A multi-furnace one-tower flue gas device for copper-containing sludge treatment

Abstract

This utility model discloses a multi-furnace, single-tower flue gas treatment device for copper-containing sludge, relating to the field of sludge treatment. It includes a settling module with a sedimentation chamber inside. The sedimentation chamber contains a sedimentation mechanism and an auxiliary mechanism, with the auxiliary mechanism located on one side of the sedimentation mechanism. This utility model slows the flow velocity of the flue gas as it enters the sedimentation chamber, allowing heavier particles to settle under gravity. A baffle plate added inside the chamber disperses the flue gas flow, extending the residence time of particles. A connected movable water pipe continuously reciprocates under mechanical linkage, uniformly spraying water mist into the flue gas, cooling it while adsorbing a large amount of particulate matter. After passing through an isolation plate, the flue gas must cross a water curtain barrier to further capture residual fine particles, which are then thoroughly flushed to the bottom of the chamber by water flow. The isolation plate's lower position than the water curtain ensures that the flue gas can pass through the water curtain area comprehensively and uniformly, enhancing the uniformity of purification.

Description

Technical Field

[0001] This utility model relates to the field of sludge treatment, specifically a multi-furnace, single-tower flue gas treatment device for copper-containing sludge. Background Technology

[0002] Multiple boilers in one tower system involve the convergence of flue gas from multiple boilers through flue ducts, which is then introduced into a large, shared absorption tower for treatment. Inside this shared absorption tower, the flue gas comes into contact with sprayed chemical liquids, undergoing a chemical reaction that efficiently removes harmful substances from the flue gas. The main advantages of this configuration are significant savings in investment and operating costs, as well as saving floor space. Furthermore, centralized treatment facilitates operation, management, and maintenance.

[0003] In existing technologies, after sludge is incinerated, the flue gas produced during incineration needs to be treated to prevent environmental pollution. The flue gas passes through a pipe and is filtered by a bag filter to remove large particulate pollutants. After further treatment, such as desulfurization and activated carbon filtration, it can be purified and then discharged into the atmosphere. However, after incinerating copper-containing sludge, the flue gas produced will contain copper-containing particles. These copper-containing particles are relatively hard and will cause significant wear to the bag filter after passing through the bag filter system, thus shortening the service life of the bag filter device and increasing the cost of sludge treatment. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a multi-furnace, single-tower flue gas device for treating copper-containing sludge, in order to solve the technical problem that after the copper-containing sludge is incinerated, the flue gas contains copper particles, which accelerates the wear of the bag filter device and thus increases the cost of sludge treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for treating multi-furnace, single-tower flue gas containing copper sludge, comprising a settling module, wherein a sedimentation chamber is provided inside the settling module, and a sedimentation mechanism and an auxiliary mechanism are provided inside the sedimentation chamber, with the auxiliary mechanism located on one side of the sedimentation mechanism. The sedimentation mechanism includes an isolation plate and a fixed water pipe, wherein both the isolation plate and the fixed water pipe are fixedly installed inside the settling module, with the isolation plate located on one side of the fixed water pipe, and strip-shaped water nozzles are installed on the outer wall of the fixed water pipe. The strip-shaped water nozzles on the outer wall of the fixed water pipe can cool the flue gas and adsorb particles in the flue gas. The auxiliary mechanism includes a baffle plate and a movable water pipe, wherein both the baffle plate and the movable water pipe are rotatably connected to the settling module, and the movable water pipe is located on top of the baffle plate. Multiple sets of water spray holes are installed on the outer wall of the movable water pipe, and the water spray holes and the baffle plate on the outer wall of the movable water pipe can accelerate the adhesion of particles in the flue gas.

[0006] By adopting the above technical solution, the flow rate of flue gas naturally slows down when it enters the sedimentation chamber with an expanded cross-sectional area, allowing heavier particles to initially settle under gravity. The baffle plate added inside the chamber can disperse the flue gas flow and prolong the residence time of particles. The connected movable water pipe continuously swings back and forth under mechanical linkage, spraying water mist evenly into the flue gas through the spray nozzles, cooling the flue gas while adsorbing a large number of particles. After passing through the baffle plate, the flue gas must pass through the water curtain barrier formed by the nozzles in the upper and lower directions of the fixed water pipe to further capture residual fine particles, and then thoroughly flush them to the bottom of the chamber by the water flow. The setting of the baffle plate below the water curtain ensures that the flue gas can pass through the water curtain area comprehensively and evenly, enhancing the uniformity of purification. This solves the technical problem that after copper-containing sludge is incinerated, the flue gas contains copper-containing particles, which will accelerate the wear of the bag filter device and thus increase the cost of sludge treatment.

[0007] Furthermore, the auxiliary mechanism also includes a motor and a drive shaft, wherein the motor is installed outside the settling module, the output end of the motor is fixedly connected to the drive shaft, the outside of the drive shaft is fixedly connected to two sets of spoilers, and the auxiliary mechanism also includes a drive disk, a drive component, a rack and a slide rail, wherein the drive disk is fixedly installed at the end of the drive shaft, one side of the drive disk is movably connected to the drive component through a protrusion, the top side of the drive component is fixedly connected to the rack, and one side of the rack is slidably connected to the slide rail through a slider;

[0008] The auxiliary mechanism also includes a gear, which is movably connected to a rack through tooth meshing, and the inside of the gear is fixedly connected to a movable water pipe.

[0009] By adopting the above technical solution, the output end of the motor drives the drive shaft to rotate, thereby causing the baffle to rotate and disturb the flue gas. At the same time, the end of the drive shaft drives the drive disc to rotate synchronously. A protrusion is installed on one side of the drive disc, which is locked inside the drive component. A rack is installed on one side of the drive component, and a slider is installed on one side of the rack, with the slider located inside the slide rail. Therefore, when the drive disc rotates, the drive component starts to move. With the cooperation of the slider and the slide rail, the drive component will reciprocate under the cooperation of the drive disc and the slider, thereby causing the rack to reciprocate. A set of gears is meshed at the top of the rack through the teeth, and the inside of the gears is connected to the movable water pipe. Therefore, when the rack reciprocates, the gears will synchronously and continuously reciprocate, thereby causing the movable water pipe to reciprocate.

[0010] Furthermore, an air intake pipe is fixedly connected to one side of the top of the settling module, and one side of the air intake pipe is connected to multiple external incinerators through multiple sets of branch pipes.

[0011] By adopting the above technical solution, multiple sets of branch pipes of the air intake pipe are connected to multiple sets of incinerators. At this time, the flue gas generated by the incineration of copper-containing sludge in the incinerator will enter the sedimentation chamber inside the sedimentation module through the air intake pipe.

[0012] Furthermore, a bag filter module is fixedly connected to one side of the settling module, a desulfurization module is fixedly connected to one side of the bag filter module, and an emission module is fixedly connected to one side of the desulfurization module.

[0013] By adopting the above technical solution, after the flue gas leaves the settling module, the harder copper-containing particles will be retained in the settling module. The remaining flue gas will be purified to the emission standard after passing through the bag filter module and the desulfurization module, and then the purified flue gas will be discharged to the outside through the emission module.

[0014] In summary, this utility model has the following beneficial effects: When flue gas enters the sedimentation chamber with an expanded cross-sectional area, the flow rate naturally slows down, allowing heavier particles to initially settle under gravity. The baffle plate added inside the chamber can disperse the flue gas flow and prolong the residence time of particles. The connected movable water pipe continuously swings back and forth under mechanical linkage, spraying water mist evenly into the flue gas through the spray nozzles, cooling the flue gas while adsorbing a large number of particles. After passing through the baffle plate, the flue gas must pass through the water curtain barrier formed by the vertical nozzles of the fixed water pipe to further capture residual fine particles, and then thoroughly flush them to the bottom of the chamber by the water flow. The setting of the baffle plate below the water curtain ensures that the flue gas can pass through the water curtain area comprehensively and evenly, enhancing the uniformity of purification. This solves the technical problem that after copper-containing sludge is incinerated, the flue gas contains copper-containing particles, which accelerates the wear of the bag filter device and increases the cost of sludge treatment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A multi-furnace, single-tower flue gas treatment device for copper-containing sludge, such as Figure 1-5 As shown, it includes a settling module 1, which has a settling chamber 3 inside. The settling chamber 3 is equipped with a settling mechanism 4 and an auxiliary mechanism 5. The auxiliary mechanism 5 is located on one side of the settling mechanism 4. After the flue gas enters the settling chamber 3 from the inlet pipe 2, the flow rate of the flue gas will slow down after entering the settling chamber 3 because the cross-sectional area of ​​the settling chamber 3 is larger than that of the inlet pipe 2. At this time, under the action of gravity, some large particles will fall to the bottom of the settling chamber 3.

[0024] Furthermore, the sedimentation mechanism 4 includes an isolation plate 401 and a fixed water pipe 402, wherein the isolation plate 401 and the fixed water pipe 402 are both fixedly installed inside the sedimentation module 1, and the isolation plate 401 is located on one side of the fixed water pipe 402. The outer wall of the fixed water pipe 402 is equipped with strip-shaped water nozzles. The strip-shaped water nozzles on the outer wall of the fixed water pipe 402 can cool the flue gas and adsorb particles in the flue gas. The auxiliary mechanism 5 includes a baffle plate 503 and a movable water pipe 509, wherein the baffle plate 503 and the movable water pipe 509 are rotatably connected to the sedimentation module 1, and the movable water pipe 509 is located on top of the baffle plate 503. The outer wall of the movable water pipe 509 is equipped with multiple sets of water spray holes, and the water spray holes on the outer wall of the movable water pipe 509 and the baffle plate 503 play a role in accelerating the adhesion of particles in the flue gas.

[0025] Multiple spray nozzles are provided on the outer side of the movable water pipe 509, which can initially cool the flue gas in the sedimentation chamber 3 and cause some particles in the flue gas to adhere to the water and fall to the bottom of the sedimentation chamber 3. After passing through the auxiliary mechanism 5, the flue gas will pass through the baffle plate 401. The exhaust pipe of the sedimentation module 1 is installed on the top side of the sedimentation chamber 3. Therefore, after passing through the baffle plate 401, the flue gas will move obliquely upward and pass through the fixed water pipe 402. Directional spray heads are installed on the upper and lower sides of the fixed water pipe 402. At the same time, the fixed water pipe 402 is connected to the external water source. Therefore, the fixed water pipe 402 will form a water curtain. After passing through the water curtain, the temperature of the flue gas will not only decrease, but some particles in the flue gas will also flow to the bottom of the sedimentation chamber 3 under the action of the water curtain. The bottom of the baffle plate 401 is lower than the position of the fixed water pipe 402, so the flue gas can pass through the water curtain of the fixed water pipe 402 evenly.

[0026] In the example, the auxiliary mechanism 5 also includes a motor 501 and a drive shaft 502. The motor 501 is installed outside the settling module 1, and the output end of the motor 501 is fixedly connected to the drive shaft 502. The outside of the drive shaft 502 is fixedly connected to two sets of baffles 503. The auxiliary mechanism 5 also includes a drive disk 504, a drive component 505, a rack 506, and a slide rail 507. The drive disk 504 is fixedly installed at the end of the drive shaft 502. One side of the drive disk 504 is movably connected to the drive component 505 through a protrusion. One side of the top of the drive component 505 is fixedly connected to the rack 506. One side of the rack 506 is slidably connected to the slide rail 507 through a slider. The auxiliary mechanism 5 also includes a gear 508. The gear 508 is movably connected to the rack 506 through tooth meshing. The inside of the gear 508 is fixedly connected to the movable water pipe 509.

[0027] The output of motor 501 drives drive shaft 502 to rotate, thereby causing spoiler 503 to rotate and disturb the flue gas. Simultaneously, the end of drive shaft 502 drives drive disk 504 to rotate synchronously. A protrusion is installed on one side of drive disk 504, which is engaged inside drive component 505. A rack 506 is installed on one side of drive component 505, and a slider is installed on one side of rack 506, located inside slide rail 507. Therefore, when drive disk 504 rotates... The drive component 505 will start to move. With the cooperation of the slider and the slide rail 507, the drive component 505 will reciprocate under the cooperation of the drive disk 504 and the slider, so that the rack 506 will reciprocate. The top of the rack 506 is connected to a set of gears 508 through teeth, and the inside of the gears 508 is connected to the movable water pipe 509. Therefore, when the rack 506 reciprocates, the gears 508 will reciprocate synchronously, so that the movable water pipe 509 can reciprocate.

[0028] In the example, an air inlet pipe 2 is fixedly connected to one side of the top of the settling module 1. One side of the air inlet pipe 2 is connected to multiple sets of external incinerators through multiple sets of branch pipes. The multiple sets of branch pipes of the air inlet pipe 2 are connected to multiple sets of incinerators. At this time, the flue gas generated by the incineration of copper-containing sludge in the incinerator will enter the sedimentation chamber 3 inside the settling module 1 through the air inlet pipe 2.

[0029] In the example, a bag filter module 6 is fixedly connected to one side of the settling module 1, a desulfurization module 7 is fixedly connected to one side of the bag filter module 6, and an emission module 8 is fixedly connected to one side of the desulfurization module 7. After the flue gas leaves the settling module 1, the harder copper-containing particles will be retained in the settling module 1. The remaining flue gas will be purified to the emission standard after passing through the bag filter module 6 and the desulfurization module 7, and then the purified flue gas will be discharged to the outside through the emission module 8.

[0030] The working principle of this utility model is as follows: When in use, the power is turned on, and the multiple branch pipes of the air inlet pipe 2 are first connected to multiple incinerators. At this time, the flue gas generated by the incineration of copper-containing sludge in the incinerator will enter the sedimentation chamber 3 inside the sedimentation module 1 through the air inlet pipe 2.

[0031] After the flue gas enters the deposition chamber 3 from the inlet pipe 2, the flow rate of the flue gas will slow down after entering the deposition chamber 3 because the cross-sectional area of ​​the deposition chamber 3 is larger than that of the inlet pipe 2. At this time, under the action of gravity, some large particles will fall to the bottom of the deposition chamber 3.

[0032] The auxiliary mechanism 5 will start after the device is powered on. The output end of the motor 501 will drive the drive shaft 502 to rotate, thereby causing the baffle 503 to rotate and disturb the flue gas. At the same time, the end of the drive shaft 502 will drive the drive disc 504 to rotate synchronously.

[0033] A protrusion is installed on one side of the drive disk 504, which is locked inside the drive component 505. A rack 506 is installed on one side of the drive component 505, and a slider is installed on one side of the rack 506. The slider is located inside the slide rail 507. Therefore, when the drive disk 504 rotates, the drive component 505 will start to move. With the cooperation of the slider and the slide rail 507, the drive component 505 will reciprocate under the cooperation of the drive disk 504 and the slider, thereby causing the rack 506 to reciprocate.

[0034] The top of the rack 506 is connected to a set of gears 508 through tooth meshing, and the inside of the gears 508 is connected to the movable water pipe 509. Therefore, when the rack 506 reciprocates, the gears 508 will reciprocate continuously, thereby causing the movable water pipe 509 to reciprocate. The other end of the movable water pipe 509 is connected to the water inlet through a hose. Therefore, the movable water pipe 509 will not interfere with the water inlet when it reciprocates. Multiple sets of water spray nozzles are opened on the outside of the movable water pipe 509, so the flue gas in the sedimentation chamber 3 can be initially cooled, and some of the particles in the flue gas will adhere to the water and fall to the bottom of the sedimentation chamber 3.

[0035] After passing through the auxiliary mechanism 5, the flue gas will pass through the baffle plate 401. The gas outlet pipe of the settling module 1 is installed on the top side of the sedimentation chamber 3. Therefore, after passing through the baffle plate 401, the flue gas will move obliquely upward and pass through the fixed water pipe 402. Directional water spray heads are installed on the upper and lower sides of the fixed water pipe 402. At the same time, the fixed water pipe 402 is connected to the external water source. Therefore, the fixed water pipe 402 will form a water curtain. After passing through the water curtain, the temperature of the flue gas will not only decrease, but some particles in the flue gas will flow to the bottom of the sedimentation chamber 3 under the action of the water curtain. The bottom of the baffle plate 401 is lower than the position of the fixed water pipe 402, so the flue gas can pass through the water curtain of the fixed water pipe 402 evenly.

[0036] After the flue gas leaves the settling module 1, the harder copper-containing particles will remain in the settling module 1. The remaining flue gas will be purified to the emission standard after passing through the bag filter module 6 and the desulfurization module 7, and then the purified flue gas will be discharged to the outside through the emission module 8.

[0037] The bottom of the deposition module 1 is equipped with a drain outlet. When the flue gas is purified, the water level inside the module will reach a certain level and the contaminated water will be evenly pumped out from the deposition chamber 3 by an external pumping mechanism. The copper-containing contaminated water can be recycled later.

[0038] The above structure can solve the technical problem that after copper-containing sludge is incinerated, the flue gas contains copper particles, which accelerates the wear of bag filter devices and increases the cost of sludge treatment.

[0039] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, but such modifications, substitutions, and variations are protected by patent law as long as they fall within the scope of the claims of the present invention.
