[0002] With the development of modern times, the industrial manufacturing industry is constantly progressing. Aluminum alloy melting and casting is an important link in modern industrial manufacturing. However, the tail gas generated during the process contains a large amount of harmful components, such as particulate matter, fluorides, sulfur dioxide, etc. These pollutants not only have a serious impact on the environment but also endanger human health. Therefore, it is crucial to carry out tail gas treatment. A tail gas treatment device refers to equipment used to reduce or eliminate harmful gas emissions generated during industrial production processes. In the field of environmental protection, the importance of tail gas treatment devices is self-evident. It is of great significance for reducing air pollution, protecting the ecological environment, and maintaining human health. With the increasingly strict environmental protection regulations, the application of tail gas treatment devices is becoming more and more widespread.

[0003] Factories usually use spray towers to treat the tail gas of aluminum alloys, purify and discharge the tail gas. However, when the tail gas volume is too large, the moisture in the discharged air will increase, and water will flow out from the spray nozzles, resulting in non-compliant discharged air quality. Moreover, the tail gas temperature of aluminum alloy melting and casting is relatively high, which will cause damage to the spray tower. For this reason, we propose a tail gas treatment device for aluminum alloy melting and casting to solve the above problems. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] This device absorbs the discharged tail gas through the intake booster fan, increases the pressure of the tail gas entering the device, the rotary intake pipe is made of heat-conducting material and can conduct heat to increase the surface temperature. The rotating box drives the rotating rod to rotate, the rotating rod drives the rotor and the solution at the bottom of the barrel shell, so that the tail gas and the solution are fully mixed, which can reduce the particulate matter in the tail gas and solve the problem of too high tail gas temperature. Due to the increase in pressure, the solution is sprayed out by the nozzle and reacts with the substances in the tail gas to purify the tail gas. The hollow balls on the grid plate will remove the particulate matter in the tail gas and waste water. When the tail gas rises and passes through the outer surface of the rotary intake pipe, part of the water vapor will evaporate, solving the problem that water will flow out of the exhaust port when a large amount of tail gas is discharged. The anode plate and the cathode tube form an electric field, so that the water and particles in the tail gas are adsorbed on the surface of the anode plate. The detection control valve can detect whether the tail gas meets the emission standard, and the intelligent control makes the tail gas always meet the emission standard.

Two air outlets 6 are provided on the outer surface of the rotor 5. Under the action of pressure, the tail gas will flow out from the air outlets 6. A water tank 7 is fixedly connected to the outer surface of the barrel shell 1. A double-headed water delivery pipe 8 is fixedly sleeved on the upper surface of the water tank 7. Two spray pipes 9 are fixedly connected to the inner side wall of the barrel shell 1. The double-headed water delivery pipe 8 is the same as the two spray pipes 9. A group of nozzles 10 are fixedly installed at the bottom end of each spray pipe 9. The nozzles 10 can spray a solution to react with the impurities in the tail gas. Two grid plates 11 are fixedly connected to the inner side wall of the barrel shell 1. A top shell 12 is fixedly connected to the upper surface of the barrel shell 1. A group of anode plates 13 are fixedly installed on the upper surface of the support frame 2. A cathode tube 14 is fixedly connected to the inner side wall of the top shell 12. The anode plates 13 and the cathode tube 14 are connected to high-voltage electricity. The anode plates 13 are connected to the positive pole, and the cathode tube 14 is connected to the negative pole to form an electric field induction, so that the moisture and particles in the tail gas are adsorbed on the surface of the anode plates 13. An exhaust pipe 15 is fixedly connected to the upper surface of the top shell 12. A rotating intake pipe 19 is fixedly connected to the outer surface of the rotating box 3.

[0021] Two observation windows 18 are provided on the outer surface of the barrel shell 1. A group of hollow balls are provided on the upper surface of each of the two grid plates 11. The hollow balls can remove the particulate matter in the tail gas and wastewater. The rotating intake pipe 19 is made of a heat-conducting material. The tail gas will increase the surface temperature of the rotating intake pipe 19. A return pipe 16 is fixedly connected to the outer surface of the barrel shell 1. The exhaust pipe 15 is connected to the return pipe 16. A detection control valve 17 is fixedly installed on the outer surface of the exhaust pipe 15.

[0022] One end of the rotating intake pipe 19 is fixedly sleeved with an intake barrel 20. A connecting frame 22 is fixedly connected to the inner side wall of the intake barrel 20. An intake booster fan 21 is fixedly connected to the outer surface of the connecting frame 22. The intake booster fan 21 absorbs the discharged tail gas and increases the pressure of the tail gas entering the interior of the device. A one-way door is provided inside the detection control valve 17. The one-way door is controlled by a motor and can control the flow direction of the treated tail gas to the exhaust pipe 15 or the return pipe 16.

The detection probe of the tail gas detection device is installed inside the exhaust pipe 15 and can detect whether the tail gas in the exhaust pipe 15 meets the emission standards through the probe and transmit the information to the detection control valve 17.

[0023] The working principle of the present utility model is:

[0024] The exhaust gas is absorbed by the intake supercharging fan 21 to increase the pressure of the exhaust gas entering the interior of the device. The exhaust gas enters the rotating intake pipe 19, which is made of heat-conducting material and can conduct heat to increase the surface temperature. The exhaust gas enters the rotating box 3. Due to the pressure, the exhaust gas flows out from the air outlet 6 of the rotor 5 through the rotating rod 4. The rotating box 3 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the rotor 5 and the solution at the bottom of the barrel shell 1. The exhaust gas and the solution are fully mixed to reduce the particulate matter in the exhaust gas and lower the temperature of the exhaust gas. The exhaust gas rises due to the pressure, and the nozzle 10 sprays the solution to react with the substances in the exhaust gas to purify the exhaust gas. The hollow balls on the grid plate 11 will remove the particulate matter in the exhaust gas and wastewater. When the exhaust gas rises and passes through the outer surface of the rotating intake pipe 19, a part of the water vapor will evaporate. When the exhaust gas passes through the anode plate 13, the anode plate 13 and the cathode tube 14 form an electric field, causing the water and particles in the exhaust gas to adsorb on the surface of the anode plate 13. The exhaust gas enters the exhaust pipe 15, and the detection control valve 17 detects whether the exhaust gas meets the emission standards. If it meets the emission standards, it is directly discharged from the exhaust pipe 15. If it does not meet the emission standards, the detection control valve 17 controls the one-way door to make the exhaust gas flow into the return pipe 16 for purification again.
