Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a germanium tetrachloride tail gas treatment device, comprising a base 1, a bracket 2 is installed on the top of the base 1, a first reaction chamber 3 is installed on the top of the bracket 2, and a guide component for guiding the tail gas to improve the contact effect with the alkaline solution is arranged inside the first reaction chamber 3; the guide component comprises a first baffle 4 and a second baffle 5, the first baffle 4 is installed on the top of the inner cavity of the first reaction chamber 3, and the second baffle 5 is installed on the bottom of the inner cavity of the first reaction chamber 3. The first baffle 4 and the second baffle 5 are arranged in a staggered shape, and a through hole 6 is opened at the bottom of the second baffle 5. The top of one side of the first reaction chamber 3 is connected with an air intake pipe, and the tail gas enters the interior of the first reaction chamber 3 through the air intake pipe. The end of the first reaction chamber 3 away from the air intake pipe is connected with a first tube body 11.

[0031] Furthermore, after the exhaust gas enters from the air intake pipe, it is discharged from the first tube body 11 and passes through the first partition plate 4 and the second partition plate 5, so that the flow of the gas inside the first reaction chamber 3 is increased.

[0032] Specifically, both sides of the first reaction chamber 3 are equipped with spray components for spraying alkaline solution into the first reaction chamber 3, and the spray components and the guide components are arranged correspondingly; the front and rear sides of the first reaction chamber 3 are provided with through grooves connected to the interior of the first reaction chamber 3, and the spray component includes a spray plate 20 installed in the through groove, and the spray end of the spray plate 20 extends to the interior of the first reaction chamber 3, and the outside of the spray plate 20 is connected with a liquid supply pipe 21. The alkaline spray liquid is transported to the interior of the spray plate 20 through the high-pressure pump and the liquid supply pipe 21, and then the alkaline solution is sprayed into the gap between the first partition plate 4 and the second partition plate 5. The gap between the first partition plate 4 and the second partition plate 5 is the only way for the exhaust gas to circulate, so that the spray liquid can be evenly and fully in contact with the exhaust gas, react with the germanium tetrachloride exhaust gas and purify the exhaust gas, and then the liquid after spraying is gathered in the interior of the first reaction chamber 3. The function of the through hole 6 can facilitate the communication of these liquids at the bottom of the inner cavity of the first reaction chamber 3.

The liquid level in the first reaction chamber 3 is monitored by the liquid level sensing probe 7. After the liquid level rises to a predetermined height, the controller 8 receives the signal transmitted by the liquid level sensing probe 7, and then sends a command to control the solenoid valve 9 to open, and the accumulated liquid will enter the interior of the energy-saving component through the solenoid valve 9.

[0034] Furthermore, an energy-saving component for secondary use of tail gas and alkaline solution is installed at the top of the base 1 and below the bracket 2, and the first reaction chamber 3 is connected to the top of the energy-saving component through a liquid level control component. The energy-saving component includes a second reaction chamber 10, which is installed at the top of the base 1 and below the first reaction chamber 3. The drainage end of the solenoid valve 9 is connected to one side of the top of the second reaction chamber 10, and the end of the first tube body 11 away from the first reaction chamber 3 is connected to one side of the second reaction chamber 10. The accumulated liquid will enter the interior of the second reaction chamber 10 through the solenoid valve 9. The second reaction chamber 10 is used to collect the residual alkaline solution generated when the tail gas is treated by spraying, and reuse it, so as to save and make full use of resources.

[0035] The energy-saving component further comprises a housing 12, which is mounted on one side of the second reaction bin 10, a motor 13 is mounted inside the housing 12, a guide plate 14 is mounted inside the second reaction bin 10, a rotating shaft 15 is rotatably mounted inside the second reaction bin 10 and on both sides of the guide plate 14, and a blade 16 is mounted on the surface of the rotating shaft 15. One end of the rotating shaft 15 rotates and extends to the inside of the housing 12, a pulley group 17 is connected between the rotating shafts 15, and the output shaft of the motor 13 is connected to one end of the rotating shaft 15 through a coupling. By starting the motor 13, the output group of the motor 13 drives the two groups of rotating shafts 15 to rotate through the pulley group 17, and the rotating shaft 15 drives the blade 16 to lift the alkaline solution, and at the same time, the exhaust gas after spraying treatment in the first reaction bin 3 will also enter the second reaction bin 10 through the first tube body 11, and when the alkaline solution is lifted, it can contact with the exhaust gas again, further react and treat the exhaust gas, and improve the utilization rate of the material and the purification effect of the exhaust gas.

[0036] Specifically, the interior of the second reaction chamber 10 is respectively formed with a first cavity 18 and a second cavity 19 through the guide plate 14, the end of the first tube body 11 away from the first reaction chamber 3 is connected to the side of the first cavity 18, the first cavity 18 and the second cavity 19 away from the side of the first tube body 11 are connected, and the bottom of the solenoid valve 9 is connected to the interior of the first cavity 18.

[0037] By setting the guide plate 14, the interior of the second reaction chamber 10 can be separated. First, the exhaust gas treated by the first spraying and the alkaline solution remaining after the spraying will enter the interior of the first cavity 18, and will enter the interior of the second cavity 19 under the guidance of the guide plate 14. This can improve the flow of the exhaust gas in the second reaction chamber 10 and improve the treatment effect of the exhaust gas.

[0038] Subsequently, an overflow pipe 22 connected to the second cavity 19 is installed on one side of the second reaction chamber 10. When the liquid in the second reaction chamber 10 submerges the overflow pipe 22, the liquid will overflow through the overflow pipe 22. The overflowed alkaline solution absorbs the germanium element, completing the treatment of germanium tetrachloride. The overflowed liquid can be collected and reused. At the same time, the overflow pipe 22 will also discharge the purified exhaust gas, which can be introduced into the next exhaust gas purification link through a pipeline.
