[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] Embodiment 1:

[0020] Please refer to Figures 1 - 3 , a tail gas treatment device for rare metal smelting, including a treatment kettle 1. A solvent tank 2 is fixedly installed on the upper surface of the treatment kettle 1. A pumping device 3 is fixedly installed on the left and right surfaces of the solvent tank 2. A water delivery pipe 4 is fixedly installed on the outer surface of the pumping device 3. A water collection tank 5 is fixedly installed on the outer surface of the treatment kettle 1. An atomizing nozzle 6 is fixedly installed on the inner wall of the water collection tank 5. A filter partition 7 is fixedly installed on the inner wall of the treatment kettle 1. An outlet 8 is arranged on the lower surface of the treatment kettle 1. An air inlet 9 is arranged on the right surface of the treatment kettle 1. An air outlet pipe 10 is arranged on the upper surface of the treatment kettle 1.

[0021] Specifically: In the process of using the present utility model, when the tail gas needs to be treated, at this time, the tail gas enters the interior of the treatment kettle 1 through the air inlet 9. Then, the controller 16 controls the pumping device 3 to start. When the pumping device 3 starts, the water in the solvent tank 2 is pumped into the water collection tank 5 through the water delivery pipe 4. The solvent pumped into the water collection tank 5 is atomized and sprayed out through the atomizing nozzle 6, so as to combine with the incoming waste gas. After the atomized solvent water adsorbs the harmful substances and impurities in the waste gas, it falls to the outlet 8 by its own gravity, and then is discharged through the outlet 8. The purified waste gas passes through the filter partition 7 and reaches the air outlet, and finally is discharged to the outside through the air outlet pipe 10.

[0022] In this implementation scheme: A controller 16 is fixedly installed on the front surface of the treatment kettle 1, and a support column 17 is fixedly installed on the lower surface of the treatment kettle 1.

[0023] In this implementation scheme: An inlet 18 is arranged on the upper surface of the solvent tank 2. The output end of the water delivery pipe 4 is fixedly connected to the upper surface of the water collection tank 5, and the inside of the water delivery pipe 4 is communicated with the inside of the water collection tank 5. The atomizing nozzle 6 is located inside the treatment kettle 1. An air vent hole is arranged on the upper surface of the treatment kettle 1, and the air vent hole is communicated with the air outlet pipe 10.

[0024] Specifically: The solvent inside the solvent tank 2 is added through the inlet 18.

[0025] In this implementation scheme: The controller 16 is electrically connected to the pumping device 3, the electromagnetic valve 15, and the air quality detector 12, and there are four support columns 17.

[0026] Specifically: The overall device is supported by the support columns 17, and four of them provide greater stability.

[0027] Working principle: In this utility model, the solvent is atomized and sprayed through the atomizing nozzle 6, so that the solvent can come into full contact with the waste gas. The function of the filtering partition 7 is to block the input waste gas, thereby slowing down its flow rate and ensuring that it can be fully mixed with the solvent. After the atomized solvent comes into contact with impurities and harmful substances, it directly discharges from the water outlet 8 by its own gravity. Compared with related technologies, a rare metal smelting tail gas treatment device provided by this utility model has the following beneficial effects: This design atomizes and sprays the solvent, so that the solvent and the waste gas can be fully contacted, improving the filtering effect and efficiency while saving economic costs.

[0028] Embodiment 2:

[0029] Please refer to Figures 1 - 3 , a detection frame 11 is fixedly installed in the middle of the air outlet pipe 10, an air quality detector 12 is fixedly installed on the front surface of the detection frame 11, a partition 13 is fixedly installed on the inner wall of the detection frame 11, a return air pipe 14 is fixedly installed on the left surface of the detection frame 11, and an electromagnetic valve 15 is fixedly installed on the outer surface of the return air pipe 14.

[0030] Specifically: When the purified air passes through the air outlet pipe 10, at this time the waste gas reaches the inside of the detection frame 11, and the partition 13 blocks it, thereby slowing down its flow rate. At this time, the air quality detector 12 detects the waste gas reaching the inside of the detection frame 11. When the detection standard is met, the waste gas directly discharges through the air outlet pipe 10. When the detection standard is not met, the electromagnetic valve 15 opens, and the waste gas is re-transported to the inside of the treatment kettle 1 through the return air pipe 14 and then re-treated until it meets the standard and then discharges.

[0031] In this implementation scheme: Through holes are provided on the surface of the partition 13, and the output end of the return air pipe 14 communicates with the lower part inside the treatment kettle 1.

[0032] Specifically: The function of the partition 13 is to block the waste gas, thereby slowing down its flow rate and facilitating the detection by the air quality sensor.

[0033] Working principle: The utility model realizes the detection of the filtered waste gas through the air quality detector 12. When it is found that the waste gas emission does not meet the standard, the electromagnetic valve 15 is opened at this time, so that the waste gas that does not reach the emission standard is re-introduced into the interior of the treatment kettle 1 and processed again. Compared with the related technology, a rare metal smelting tail gas treatment device provided by the utility model has the following beneficial effects: This design can achieve the effect of detecting the waste gas, so as to timely understand the treatment situation of the waste gas, adjust according to the standard, improve the treatment efficiency and stability, and avoid the situation that the waste gas is discharged outdoors before being completely treated.

[0034] The controller 16 is of an existing structure, and the control circuit can be realized by simple programming of those skilled in the art, which belongs to the common general knowledge in the art. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0035] For the selection of each device in the above-mentioned equipment use, different selections are made according to the actual situation, and various parameters are referred to, and the functions of the used equipment are echoed with the achieved effects.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
