Description

[0002] Aviation fuel refers to some types of fuel specially designed for aircraft. It is of higher quality than the fuel used in heating systems and cars, and usually contains different additives to reduce the risk of freezing and explosion due to high temperature.

These wastes need to be treated with specific agents before they can be discharged to avoid pollution to the environment.

[0033] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the precipitation structure 4 includes a feeding port 410, a feeding port 410 is provided on the side of the precipitation tank 2, a first motor 402 is installed on the side of the precipitation tank 2, an end of the first motor 402 is fixedly connected to a stirring shaft 404 through a coupling, an end of the stirring shaft 404 is rotatably connected to the precipitation tank 2, and both ends of the precipitation tank 2 are respectively fixedly connected to a return air pipe 401 and a connecting pipe 409, the other end of the return air pipe 401 is connected to one end of the scrubbing chamber 1 where the air inlet 301 is provided, and the other end of the connecting pipe 409 is connected to the waste liquid tank 601 through a discharge port 605. The middle part of the connecting pipe 409 is in a "U"-shaped structure. A second motor 403 is installed at the end of the sedimentation tank 2. The end of the second motor 403 is fixedly connected to a spiral feeding rod 405 through a coupling. The end of the spiral feeding rod 405 is rotatably connected to the sedimentation tank 2. A discharge trough 406 is provided on the bottom side of the sedimentation tank 2. A filter screen 407 is fixedly connected to the bottom side of the sedimentation tank 2. An outlet pipe 408 is provided on the bottom side of the filter screen 407. The outlet pipe 408 runs through the side wall of the sedimentation tank 2. The waste liquid and the waste gas generated by the treatment can be further treated by the sedimentation structure 4, that is: located at The sedimentation tank 2 at the bottom of the scrubbing chamber 1 is used to treat the waste liquid generated by the distillation of aviation fuel. After the waste liquid and the reaction reagent are injected into the sedimentation tank 2 from the feeding port 410, the first motor 402 and the second motor 403 are connected to the external power supply. The first motor 402 is started to drive the stirring shaft 404 inside the sedimentation tank 2 to stir and mix the waste liquid, so that the reagent and the waste liquid are fully reacted. After the reaction is completed, the stirring is stopped. At this time, the impurities in the solution will settle to the bottom of the sedimentation tank 2. A water outlet pipe 408 is provided at the tail end of the sedimentation tank 2. After the filtering effect of the filter screen 407, the treated liquid can be discharged through the water outlet pipe 408 Liquid, and for the sediment in the sedimentation tank 2, the user can start the second motor 403, so that the second motor 403 drives the spiral feeding rod 405 to rotate, and at the same time transports the sediment to the discharge trough 406 and discharges it, that is, completes the treatment of the waste liquid. In this process, the mixed liquid in the waste liquid tank 601 in the top side washing chamber 1 will be discharged into the sedimentation tank 2 through the connecting pipe 409 for mixing, saving subsequent processing resources, and at the same time, the waste gas generated during the waste liquid reaction will be discharged into the washing chamber 1 through the return air pipe 401, so that the waste gas generated in the sedimentation tank 2 can be treated together, effectively reducing the pollution level of the emissions.

[0034] When the present invention is in use, first, the waste gas enters through the air inlet 301 on the side of the scrubbing chamber 1. When the scrubbing process is performed, the operator needs to input the purification liquid through the spray liquid pipe 302, and spray it out through the spray port 308 on the spray liquid pipe 302 to purify the introduced waste gas. A plurality of liquid collecting tanks 309 are provided on the bottom side of the scrubbing chamber 1 for collecting the sprayed liquid, and partitions 311 and lifting plates 307 are provided between the liquid collecting tanks 309.

The separation effect makes the channel in the scrubbing chamber 1 present an "S"-shaped structure, thereby greatly prolonging the contact time between the exhaust gas and the liquid medicine and improving the purification effect. On the other hand, the water pump 303 located outside the scrubbing chamber 1 can transport the liquid medicine in the collecting tank 309 to the top of another adjacent collecting tank 309 through the liquid suction pipe 304 and the liquid discharge pipe 305, and repeatedly spray it through the spray port 308 on the bottom side of the liquid discharge pipe 305, so as to give full play to the purification effect of the liquid medicine, and ensure a good purification effect on the exhaust gas while recycling the liquid medicine. An exhaust port 501 is provided at the tail end of the scrubbing chamber 1 for discharging the purified exhaust gas.

After the reagent is recycled for multiple times, the exhaust gas is fully purified and then discharged through the exhaust port 501, and the medicinal liquid will eventually be discharged into the waste liquid tank 601 through the liquid discharge pipe 305. Due to the full reaction between the medicinal liquid and the exhaust gas, there will also be impurities therein. In order to facilitate the full discharge of the mixed waste liquid for further treatment, the rotation of the drive shaft 507 at the end of the motor will drive the stirring paddle 604 to continuously stir the waste liquid through the transmission effect of the first bevel gear 602 and the second bevel gear 603, thereby avoiding impurities in the mixed liquid. The impurities are concentrated and precipitated, which is convenient for the overall discharge of the mixed liquid. At the same time, as the waste liquid tank 601 is gradually filled with the mixed liquid, the second buoyancy block 607 will float up and pull the sealing plug 606 to slide along the guide rod 609 to the top side, and at the same time, the discharge port 605 on the bottom side of the waste liquid tank 601 is opened to discharge the mixed liquid from the scrubbing chamber 1. The sedimentation tank 2 located at the bottom side of the scrubbing chamber 1 is used to treat the waste liquid generated by the distillation of aviation fuel. After the waste liquid and the reaction agent are injected into the sedimentation tank 2 from the feeding port 410, the first motor 402 and the second motor 403 are connected to an external power supply. Starting the first motor 402 can drive the stirring shaft 404 inside the sedimentation tank 2 to stir and mix the waste liquid, so that the agent and the waste liquid are fully reacted. After the reaction is completed, the stirring is stopped.At this time, the impurities in the solution will settle to the bottom of the sedimentation tank 2. A water outlet pipe 408 is provided at the tail end of the sedimentation tank 2. After the filtering effect of the filter net 407, the treated liquid can be discharged through the water outlet pipe 408. For the sediment in the sedimentation tank 2, the user can start the second motor 403, so that the second motor 403 drives the spiral feeding rod 405 to rotate, and at the same time, the sediment is transported to the discharge trough 406 and discharged, that is, the treatment of the waste liquid is completed. In this process, the mixed liquid in the waste liquid tank 601 in the top side washing chamber 1 will be discharged into the sedimentation tank 2 through the connecting pipe 409 for mixing, saving subsequent processing resources. At the same time, the waste gas generated during the waste liquid reaction will be discharged into the washing chamber 1 through the return air pipe 401, so that the waste gas generated in the sedimentation tank 2 can be processed together, effectively reducing the pollution level of the emissions.
