Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and in particular to a waste incineration deacidification device. Background Technology

[0002] Currently, incineration is one of the main methods of waste disposal. However, in the process of incinerating waste, in addition to causing secondary environmental pollution, it also wastes resources and energy. Therefore, incineration can be used in waste disposal. The flue gas produced by incineration contains a large number of harmful substances, including particulate harmful dust and harmful gases dissolved in the air. This flue gas needs to be treated again before it can be discharged into the atmosphere.

[0003] Wet desulfurization is a device used to treat acidic gases in flue gas to ensure that the gas meets environmental emission standards. When using a desulfurization device to treat flue gas, the flue gas produced by combustion is at a high temperature. When the flue gas continuously enters the desulfurization device through the flue gas inlet pipe, the connection between the flue gas inlet pipe and the device may be subjected to great pressure due to the high temperature of the flue gas. Over time, this may cause the connection between the flue gas inlet pipe and the device to break and loosen, resulting in flue gas leakage. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when flue gas continuously enters the desulfurization device through the flue gas inlet pipe, the connection between the flue gas inlet pipe and the device may be subjected to great pressure due to the high temperature of the flue gas, which may cause the connection between the flue gas inlet pipe and the device to break and loosen over time, resulting in flue gas leakage. Therefore, a waste incineration desulfurization device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste incineration deacidification device, comprising a housing, an inlet pipe provided on one side of the housing, a filter plate provided inside the housing for filtering particles in the flue gas entering the housing, a transfer pipe provided on the outer surface of the housing, a spray pipe provided at the top of the inner wall of the housing, a plurality of nozzles provided on the outer surface of the spray pipe, an exhaust pipe provided at the top of the housing, an observation window provided on one side of the outer surface of the housing, and buffer devices provided on both sides of the inlet pipe.

[0006] The effect achieved by the above components is as follows: When using the deacidification device, the flue gas conveying pipe is connected to one end of the flue gas inlet pipe, and then the alkaline solution is connected to one end of the spray pipe. The flue gas enters the interior of the box through the flue gas inlet pipe, first entering the lower half of the box and filtering the particles in the flue gas through the filter screen on the surface of the filter plate. Then the flue gas will enter the upper half of the box through the transfer pipe. At this time, the alkaline solution is sprayed out through the nozzle on the outer surface of the spray pipe and neutralizes the acidic gas in the flue gas. After the deacidification is completed, the gas is discharged through the exhaust pipe at the top of the box.

[0007] Preferably, the buffer device includes a connecting pipe, with both ends of the connecting pipe fixedly connected to one side of the smoke inlet pipe and one side of the inner wall of the housing, respectively. A rotating shaft is rotatably connected to the inner wall of the connecting pipe, and a stop block is fixedly connected to the outer surface of the rotating shaft. A circular block is fixedly connected to one end of the rotating shaft, and a steel rope is provided on the outer surface of the circular block. A rectangular block is fixedly connected to one side of the connecting pipe, and a U-shaped block is slidably connected to the outer surface of the rectangular block. Two springs are provided on one side of the U-shaped block, with both ends of the two springs fixedly connected to one side of the U-shaped block and one side of the rectangular block, respectively. Both ends of the steel rope are fixedly connected to one side of the U-shaped block and one side of the circular block, respectively.

[0008] The effect achieved by the above components is as follows: By setting up the baffles, when using the desulfurization device, if the pressure inside the flue gas increases due to the high temperature of the flue gas during the process of flue gas entering the chamber through the flue gas inlet pipe, the high pressure will push the baffles inside the connecting pipes on both sides of the flue gas inlet pipe to drive the rotating shaft to rotate. This causes the round block at one end of the rotating shaft to wrap one end of the steel rope around the surface and pull the two ends of the U-shaped block to slide on the outer surface of the rectangular block through the steel rope, while compressing the spring. This causes the baffles to be tilted relative to the inner wall of the connecting pipe. At this time, the flue gas inside the flue gas inlet pipe can enter the chamber through the connecting pipe, relieving the pressure inside the flue gas inlet pipe. When the pressure inside the flue gas inlet pipe decreases, the spring returns to its original state and pushes the U-shaped block to move away from the rectangular block and pulls the steel rope to rotate the rotating shaft. The baffles on the outer surface of the rotating shaft will seal the inside of the connecting pipe, and the flue gas will only enter the chamber through the flue gas inlet pipe.

[0009] Preferably, two round rods are fixedly connected to one side of the rectangular block, and the inner wall of the U-shaped block slides on the outer surface of the two round rods.

[0010] The effect achieved by the above components is that when the U-shaped block is displaced, it will move on the outer surface of the two round rods. The round rods can further limit the angle between the U-shaped block, the rectangular block, and the connecting pipe, so as to avoid the U-shaped block from tilting as much as possible.

[0011] Preferably, a support rod is fixedly connected to one side of the rectangular block, and the end of the support rod away from the rectangular block is fixedly connected to the outer surface of the connecting pipe.

[0012] The effect achieved by the above components is that by setting up support rods, the connection between the rectangular block and the connecting pipe can be supported and reinforced, thereby improving the structural strength of the connection between the rectangular block and the connecting pipe.

[0013] Preferably, a sealing sheet is fixedly connected to the outer surface of the connecting pipe, and the sealing sheet is located outside the connection between the rotating shaft and the connecting pipe.

[0014] The effect achieved by the above components is that by setting a sealing plate, the outer side of the connection between the rotating shaft and the connecting pipe can be further sealed, so as to avoid the leakage of flue gas through the connection between the rotating shaft and the connecting pipe as much as possible.

[0015] Preferably, a retaining ring is fixedly connected to one side of the circular block, and the retaining ring is located at the end of the circular block away from the retaining block.

[0016] The effect achieved by the above components is that by setting the retaining ring, the position of the steel rope on the outer surface of the circular block can be restricted, preventing the steel rope from sliding laterally off the surface of the circular block when the circular block rotates and wraps around it.

[0017] Preferably, a positioning device is provided on one side of the U-shaped block. The positioning device includes a protrusion, one side of which is fixedly connected to one side of the U-shaped block. A screw is threadedly connected to the inner wall of the protrusion, and a pad is fixedly connected to one end of the screw.

[0018] The effects achieved by the above components are as follows: when using the deacidification device, the screw can be rotated on one side of the two connecting pipes to control the screw to move on the inner wall of the protrusion, and the position of the pad can be adjusted to move away from or closer to the rectangular block. The movement range of the U-shaped block can be limited by the screw and the pad, and the rotation range of the stop block can be limited or the position of the stop block can be locked. This makes it easier to select whether the buffer device is in operation according to the actual situation, and improves the flexibility of the buffer device when it is used.

[0019] Preferably, an operating block is fixedly connected to the end of the screw away from the pad, and the outer surface of the operating block is provided with several protrusions.

[0020] The effect achieved by the above components is that the protrusions on the outer surface of the operating block make it easier to rotate the operating block to control the screw rotation and prevent the hand from slipping.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a buffer device is provided, and connecting pipes are installed on both sides of the smoke inlet pipe, so that the two ends of the connecting pipes are respectively connected to the inside of the housing and the inside of the smoke inlet pipe. When the pressure inside the smoke inlet pipe is too high, the baffle inside the connecting pipe will rotate to open the inside of the connecting pipe, allowing some flue gas to enter the housing through the inside of the connecting pipe, thereby relieving the pressure inside the smoke inlet pipe and avoiding loosening and breakage at the connection between the smoke inlet pipe and the housing due to excessive pressure caused by high-temperature flue gas as much as possible.

[0030] Example 1, as Figure 1-2 As shown, a waste incineration desulfurization device includes a housing 1, an inlet pipe 4 on one side of the housing 1, a filter plate 7 inside the housing 1 for filtering particles in the flue gas entering the housing 1, a transfer pipe 8 on the outer surface of the housing 1, a spray pipe 9 at the top of the inner wall of the housing 1 with several nozzles on its outer surface, an exhaust pipe 6 at the top of the housing 1, an observation window 5 on one side of the outer surface of the housing 1, and buffer devices 2 on both sides of the inlet pipe 4. When in use, connect one end of the flue gas conveying pipe to the inlet pipe 4, and then connect the alkaline solution to one end of the spray pipe 9. The flue gas enters the interior of the box 1 through the inlet pipe 4 and first enters the lower half of the box 1. The particles in the flue gas are filtered by the filter screen on the surface of the filter plate 7. Then the flue gas enters the upper half of the box 1 through the transfer pipe 8. At this time, the alkaline solution is sprayed out through the nozzle on the outer surface of the spray pipe 9 and neutralizes the acidic gas in the flue gas. After the acid removal is completed, the gas is discharged through the exhaust pipe 6 at the top of the box 1.

[0031] Reference Figure 1-6As shown in this embodiment: the buffer device 2 includes a connecting pipe 21, with both ends of the connecting pipe 21 fixedly connected to one side of the smoke inlet pipe 4 and one side of the inner wall of the housing 1, respectively. A rotating shaft 22 is rotatably connected to the inner wall of the connecting pipe 21, and a stop block 23 is fixedly connected to the outer surface of the rotating shaft 22. A round block 24 is fixedly connected to one end of the rotating shaft 22, and a steel rope 25 is provided on the outer surface of the round block 24. A rectangular block 26 is fixedly connected to one side of the connecting pipe 21, and a U-shaped block 27 is slidably connected to the outer surface of the rectangular block 26. Two springs 28 are provided on one side of the U-shaped block 27. The two ends of 28 are fixedly connected to one side of U-shaped block 27 and one side of rectangular block 26, respectively. The two ends of steel rope 25 are fixedly connected to one side of U-shaped block 27 and one side of round block 24, respectively. By setting the baffle 23, when using the deacidification device, if the flue gas enters the box 1 through the flue gas inlet pipe 4 and the pressure inside the flue gas inlet pipe 4 increases due to the high temperature of the flue gas, the high pressure will push the baffle 23 inside the connecting pipe 21 on both sides of the flue gas inlet pipe 4 to drive the rotating shaft 22 to rotate. This causes the round block 24 at one end of the rotating shaft 22 to wrap one end of the steel rope 25 around the surface and pass through the steel... The rope 25 pulls the two ends of the U-shaped block 27 to slide on the outer surface of the rectangular block 26, while simultaneously compressing the spring 28, causing the stop block 23 to be tilted relative to the inner wall of the connecting pipe 21. At this time, the flue gas inside the smoke inlet pipe 4 can enter the interior of the housing 1 through the connecting pipe 21, relieving the pressure inside the smoke inlet pipe 4. When the pressure inside the smoke inlet pipe 4 decreases, the spring 28 returns to its original state, pushing the U-shaped block 27 to move away from the rectangular block 26 and pulling the steel rope 25 to rotate the shaft 22. The stop block 23 on the outer surface of the shaft 22 will then seal the interior of the connecting pipe 21, allowing the flue gas to pass through only... The flue gas enters the housing 1 through the inlet pipe 4. A buffer device 2 is installed, and connecting pipes 21 are installed on both sides of the inlet pipe 4, so that the two ends of the connecting pipes 21 are connected to the inside of the housing 1 and the inside of the inlet pipe 4, respectively. When the pressure inside the inlet pipe 4 is too high, the baffle 23 inside the connecting pipe 21 will rotate to open the inside of the connecting pipe 21, so that some flue gas can enter the housing 1 through the inside of the connecting pipe 21, thereby relieving the pressure inside the inlet pipe 4 and preventing the connection between the inlet pipe 4 and the housing 1 from loosening and breaking due to excessive pressure caused by high temperature flue gas.

[0032] Reference Figure 2-6 As shown in this embodiment: Two round rods 29 are fixedly connected to one side of the rectangular block 26. The inner wall of the U-shaped block 27 slides on the outer surface of the two round rods 29. When the U-shaped block 27 is displaced, it will move on the outer surface of the two round rods 29. The round rods 29 can further limit the angle between the U-shaped block 27, the rectangular block 26, and the connecting pipe 21, so as to avoid the angle of the U-shaped block 27 from deflecting as much as possible. A support rod 210 is fixedly connected to one side of the rectangular block 26. The end of the support rod 210 away from the rectangular block 26 is fixedly connected to the outer surface of the connecting pipe 21. By setting the support rod 210, the connection between the rectangular block 26 and the connecting pipe 21 can be supported and reinforced, thereby improving the structural strength of the connection between the rectangular block 26 and the connecting pipe 21.

[0033] Reference Figure 2-6 As shown in this embodiment: a sealing plate 211 is fixedly connected to the outer surface of the connecting pipe 21. The sealing plate 211 is located outside the connection between the rotating shaft 22 and the connecting pipe 21. By setting the sealing plate 211, the outer side of the connection between the rotating shaft 22 and the connecting pipe 21 can be further sealed, so as to avoid the leakage of flue gas through the connection between the rotating shaft 22 and the connecting pipe 21 as much as possible. A retaining ring 212 is fixedly connected to one side of the round block 24. The retaining ring 212 is located at the end of the round block 24 away from the retaining block 23. By setting the retaining ring 212, the position of the steel rope 25 on the outer surface of the round block 24 can be restricted, so as to prevent the steel rope 25 from sliding laterally away from the surface of the round block 24 when the round block 24 rotates and wraps around the steel rope 25.

[0034] Reference Figure 1-6 As shown in this embodiment: a positioning device 3 is provided on one side of the U-shaped block 27. The positioning device 3 includes a protrusion 31. One side of the protrusion 31 is fixedly connected to one side of the U-shaped block 27. A screw 32 is threadedly connected to the inner wall of the protrusion 31. A pad 33 is fixedly connected to one end of the screw 32. When using the deacidification device, the screw 32 can be rotated on one side of the two connecting pipes 21 to control the movement of the screw 32 on the inner wall of the protrusion 31. The position of the pad 33 can be adjusted to move away from or closer to the rectangular block 26. The movement range of the U-shaped block 27 is limited by the screw 32 and the pad 33, and the rotation range of the stop block 23 is limited or the position of the stop block 23 is locked. This makes it easier to select whether the buffer device 2 is to operate according to the actual situation, and improves the flexibility of the buffer device 2 when used. An operating block 34 is fixedly connected to the end of the screw 32 away from the pad 33. Several protrusions are provided on the outer surface of the operating block 34. Holding the protrusions on the outer surface of the operating block 34 makes it easier to rotate the operating block 34 to control the rotation of the screw 32 and prevents the hand from slipping.

[0035] Working principle: When using the deacidification device, connect one end of the flue gas conveying pipe to the inlet pipe 4, and then connect one end of the alkaline solution to the spray pipe 9. The flue gas enters the interior of the chamber 1 through the inlet pipe 4, first entering the lower half of the chamber 1 and being filtered by the filter screen on the surface of the filter plate 7 to remove particles from the flue gas. Then, the flue gas enters the upper half of the chamber 1 through the transfer pipe 8. At this time, the alkaline solution is sprayed out through the nozzle on the outer surface of the spray pipe 9, which neutralizes the acidic gas in the flue gas. After the deacidification is completed, the gas is discharged through the exhaust pipe 6 at the top of the chamber 1. If the temperature of the flue gas increases and the pressure increases inside the inlet pipe 4 during the process of the flue gas entering the interior of the chamber 1 through the inlet pipe 4, the high pressure will push the baffle 23 inside the connecting pipe 21 on both sides of the inlet pipe 4 to drive the rotating shaft 22 to rotate. This causes the round block 24 at one end of the rotating shaft 22 to wrap one end of the steel rope 25 around the surface, and the steel rope 25 pulls the two ends of the U-shaped block 27 on the outer surface of the rectangular block 26. While sliding, the spring 28 is compressed, causing the stop block 23 and the inner wall of the connecting pipe 21 to be in an inclined state. At this time, the flue gas inside the flue pipe 4 can enter the interior of the box 1 through the connecting pipe 21, relieving the pressure inside the flue pipe 4. When the pressure inside the flue pipe 4 decreases, the spring 28 returns to its original state, pushing the U-shaped block 27 to move away from the rectangular block 26 and pulling the steel rope 25 to rotate the shaft 22. The stop block 23 on the outer surface of the shaft 22 will seal the interior of the connecting pipe 21, and the flue gas will only enter the interior of the box 1 through the flue pipe 4. When the deacidification device is not in use, the screw 32 can be rotated on one side of the two connecting pipes 21 to control the screw 32 to move on the inner wall of the protrusion 31, and adjust the position of the pad 33 away from or close to the rectangular block 26. The movement range of the U-shaped block 27 is limited by the screw 32 and the pad 33, and the rotation range of the stop block 23 is limited or the position of the stop block 23 is locked, so as to facilitate the selection of whether the buffer device 2 operates according to the actual situation.
