Description

Technical Field

[0001] This utility model relates to the field of rotating support technology, and in particular to a spray device for treating exhaust gas from carbon fiber production. Background Technology

[0002] The carbon fiber production exhaust gas treatment spray device is a device used to treat the exhaust gas generated during the carbon fiber production process. It removes harmful substances from the exhaust gas by spraying. The spray liquid (such as water or chemical agents) comes into full contact with the exhaust gas to adsorb, settle, or neutralize particulate matter and harmful gases (such as dimethyl sulfoxide and acrylonitrile) in the exhaust gas, thereby achieving the purpose of purifying the waste gas.

[0003] In the existing technology, carbon fiber production exhaust gas treatment spray devices mostly adopt a fixed nozzle design, with a fixed spray angle and coverage area, resulting in uneven distribution of spray liquid and the existence of local uncovered areas in the treatment space, which affects the overall uniformity of exhaust gas treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing carbon fiber production exhaust gas treatment spray devices, which mostly employ fixed nozzle designs and have fixed spray angles and coverage areas. Therefore, this invention proposes a carbon fiber production exhaust gas treatment spray device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon fiber production exhaust gas treatment spray device, comprising a treatment tank, an air inlet pipe, and a sewage outlet pipe. The treatment tank is equipped with a rotating device, which includes a servo motor. One side of the servo motor is fixedly connected to the treatment tank. A transmission rod is fixedly connected to the output end of the servo motor. A main synchronous pulley is fixedly connected to one end of the transmission rod. A synchronous belt is sleeved around the main synchronous pulley. A driven synchronous pulley is sleeved inside the synchronous belt. An inner tube is fixedly connected to the inner side of the driven synchronous pulley. A water supply pipe is fixedly connected to one end of the inner tube. Several nozzles are fixedly connected to one side of the water supply pipe. An outer tube is rotatably connected to the outside of the inner tube. A water receiving pipe is fixedly connected to one end of the outer tube. The arc surface of the water receiving pipe is fixedly connected to the treatment tank.

[0006] The effect achieved by the above components is that the servo motor starts and drives the transmission rod to rotate, which in turn drives the main synchronous pulley to rotate and drives the synchronous belt to rotate. The slave synchronous pulley then drives the inner tube to rotate, which in turn drives the water pipe to rotate the nozzle around the inner tube.

[0007] Preferably, the inner tube has a rotating ring rotatably connected to its arc surface.

[0008] The effect achieved by the above components is that the rotating ring is assembled on the inner tube.

[0009] Preferably, a baffle is fixedly connected to the arc surface of the rotating ring, and the arc surface of the baffle is fixedly connected to the processing tank.

[0010] The aforementioned components achieve the following effect: the rotating ring is fixed to the baffle, and the baffle is fixed to the processing tank.

[0011] Preferably, an exhaust pipe is fixedly connected to one side of the baffle, and the arc surface of the exhaust pipe is fixedly connected to the treatment tank.

[0012] The effect achieved by the above components is that the exhaust pipe is fixed to the baffle and the treatment tank.

[0013] Preferably, the arc surface of the transmission rod is rotatably connected to a ring, the arc surface of the ring is fixedly connected to a fixing block, and one end of the fixing block is fixedly connected to the processing tank.

[0014] The effect achieved by the above components is that the transmission rod rotates on the ring, and the fixed block provides stable support for the transmission rod.

[0015] Preferably, the outside of the treatment tank is provided with a filtration device, the filtration device including a fixing plate, one end of the fixing plate being fixedly connected to the treatment tank, and a support frame being fixedly connected to one side of the fixing plate.

[0016] The aforementioned components achieve the following effect: the support frame is fixed to the fixing plate, and the fixing plate is fixed to the processing tank.

[0017] Preferably, a purification box is fixedly connected to one side of the support frame, and one side of the purification box is fixedly connected to the air inlet pipe.

[0018] The effect achieved by the above components is that the purification box is fixed on the support frame and connected to the air inlet pipe.

[0019] Preferably, a pipe is fixedly connected to one side of the purification box, and a cover plate is slidably connected to one end of the purification box.

[0020] The effect achieved by the above-mentioned components is to provide cover for the purification chamber.

[0021] Preferably, a concave plate is fixedly connected to the inner side of the purification box, and a metal mesh filter plate is slidably connected inside the concave plate.

[0022] The effect achieved by the above components is that the metal mesh filter plate is assembled on the concave plate and placed inside the purification chamber.

[0023] In summary, the beneficial effects of this utility model are as follows: In this invention, a rotating device is used to activate the spray system when exhaust gas treatment is required. This allows the spray liquid to be sprayed from the nozzle through the outer pipe, inner pipe, and water supply pipe. Simultaneously, the exhaust gas enters the treatment tank through the air inlet pipe. The servo motor is then activated to drive the inner pipe to rotate, causing the nozzle to spray in a circular motion, thus expanding the coverage area. This rotating device solves the problem that traditional carbon fiber production exhaust gas treatment spray devices often use a fixed nozzle design, resulting in a fixed spray angle and coverage area.

[0024] In this invention, when pretreatment of exhaust gas is required, the exhaust gas enters the purification box through the connecting pipe via a filtration device. After impurities are filtered through the metal mesh filter plate, it is then transported to the air inlet pipe for subsequent processes. This filtration device solves the problem that traditional carbon fiber production exhaust gas treatment spray devices are not convenient for pretreatment of exhaust gas, resulting in solid impurities in the exhaust gas not being pretreated. During the spraying process, these impurities will carry some of the absorbent liquid to form a "liquid-solid mixture," leading to a decrease in the effective utilization rate of the spray liquid.

The output end of the servo motor 201 is fixedly connected to a transmission rod 202. One end of the transmission rod 202 is fixedly connected to a main synchronous pulley 203. A synchronous belt 204 is sleeved on the outside of the main synchronous pulley 203. A driven synchronous pulley 205 is sleeved inside the synchronous belt 204. An inner tube 215 is fixedly connected to the inside of the driven synchronous pulley 205. A water supply pipe 208 is fixedly connected to one end of the inner tube 215. Several nozzles 209 are fixedly connected to one side of the water supply pipe 208. An outer tube 206 is rotatably connected to the outside of the inner tube 215. A water receiving pipe 207 is fixedly connected to one end of the outer tube 206. The arc surface of the water receiving pipe 207 is fixedly connected to the processing tank 1. The system achieves the effect of servo motor 201 starting and outputting to drive transmission rod 202 to rotate, causing main synchronous pulley 203 to rotate and drive synchronous belt 204 to drive, which in turn drives inner tube 215 to rotate via driven synchronous pulley 205, causing water pipe 208 to drive nozzle 209 to rotate around inner tube 215. A rotating ring 211 is rotatably connected to the arc surface of inner tube 215, achieving the effect of rotating ring 211 being mounted on inner tube 215. A baffle 212 is fixedly connected to the arc surface of rotating ring 211, and the arc surface of baffle 212 is fixedly connected to treatment tank 1, achieving the effect of rotating ring 211 being fixed to baffle 212, and baffle 212 being fixed to treatment tank 1. An exhaust pipe 210 is fixedly connected to one side of baffle 212, and the arc surface of exhaust pipe 210 is fixedly connected to treatment tank 1, achieving the effect of exhaust pipe 210 being fixed to baffle 212 and treatment tank 1. A circular ring 213 is rotatably connected to the arc surface of the transmission rod 202, and a fixing block 214 is fixedly connected to the arc surface of the circular ring 213. One end of the fixing block 214 is fixedly connected to the processing tank 1. This achieves the effect of the transmission rod 202 rotating on the circular ring 213, with the fixing block 214 providing stable support for the transmission rod 202.

[0030] Reference Figure 4 As shown in this embodiment: the filter device 3 includes a fixing plate 31, one end of which is fixedly connected to the treatment tank 1, and a support frame 32 is fixedly connected to one side of the fixing plate 31. This achieves the effect of the support frame 32 being fixed to the fixing plate 31, and the fixing plate 31 being fixed to the treatment tank 1. A purification box 33 is fixedly connected to one side of the support frame 32, and one side of the purification box 33 is fixedly connected to the air inlet pipe 4. This achieves the effect of the purification box 33 being fixed to the support frame 32 and connected to the air inlet pipe 4. A connecting pipe 37 is fixedly connected to one side of the purification box 33, and a cover plate 36 is slidably connected to one end of the purification box 33. This achieves the effect of the cover plate 36 shielding the purification box 33. A concave plate 34 is fixedly connected to the inner side of the purification box 33, and a metal mesh filter plate 35 is slidably connected inside the concave plate 34. This achieves the effect of the metal mesh filter plate 35 being assembled on the concave plate 34 and located inside the purification box 33.

[0031] Working principle: When exhaust gas needs to be treated, the operator first connects the water inlet pipe 207 to the spray system via the rotating device 2, allowing the spray liquid to be transported to the inner pipe 215 through the outer pipe 206, and then sprayed out from the nozzle 209 through the water supply pipe 208. At the same time, the exhaust gas to be treated enters the treatment tank 1 through the air inlet pipe 4. At this time, the servo motor 201 is started, and its output shaft drives the transmission rod 202 to rotate, causing the main synchronous pulley 203 to drive the slave synchronous pulley 205 through the synchronous belt 204, thereby driving the inner pipe 215 to make a circular motion under the support of the outer pipe 206. As the inner tube 215 rotates, the water supply pipe 208 and the nozzle 209 connected to it rotate synchronously, causing the nozzle 209 to rotate and spray around the outer tube 206 as the axis, thereby expanding the spray angle and coverage of the spray liquid, ensuring that the exhaust gas is in full contact with the spray liquid during the rising process, and achieving efficient absorption and purification of pollutants. The treated clean gas is finally discharged through the exhaust pipe 210. Through the rotating device 2, the problem of fixed spray angle and coverage of traditional carbon fiber production exhaust gas treatment spray devices is solved.

[0032] When pretreatment of exhaust gas is required via the filter device 3, the operator first assembles the fixing plate 31 into the preset position of the treatment tank 1, and uses the support frame 32 to fix the purification box 33 and the air inlet pipe 4. At this time, the exhaust gas to be treated is first introduced into the purification box 33 through the pipe 37. In the purification box 33, the metal mesh filter plate 35 completes the preliminary filtration (intercepting solid impurities such as carbon fiber short filaments and dust). The pretreated clean exhaust gas is then transported from the outlet of the purification box 33 to the air inlet pipe 4 and enters the subsequent treatment process. The filter device 3 solves the problem that traditional carbon fiber production exhaust gas treatment spray devices are not convenient for pretreatment of exhaust gas, resulting in solid impurities in the exhaust gas not being pretreated. During the spraying process, they will carry some absorbent liquid to form a "liquid-solid mixture", which leads to a decrease in the effective utilization rate of the spray liquid.
