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.

[0023] See also Figure 1-4 The utility model provides a technical solution: a treatment device for effectively removing odor from tantalum and niobium smelting waste gas, comprising a cart 1, a filter box 2, an air intake pipe 3, an air pump 4, a filter plate 5, a waste residue box 6, an activated carbon adsorption plate 7, a spray box 8, a spray pipe 9, a sewage pipe 10, a fan 11, a treatment box 12, a motor 13, a stirring rod 14, a feeding pipe 15, a circulation pipe 16, an exhaust pipe 17 and a monitor 18, such as Figure 1 and Figure 3As shown, fixed casters are installed at the four corners of the lower surface of the cart 1, and push handles are installed on the left and right sides of the cart 1. The brake pads above the fixed casters are opened, and the push handles are held and the cart 1 is pushed. A processing device is installed on the upper surface of the cart 1. The cart 1 supports and stabilizes the processing device, which is convenient for moving the processing device. The cart 1 is pushed to a suitable position. A filter box 2 is installed at the left end of the upper surface of the cart 1. An air intake pipe 3 is installed on the left side of the filter box 2. The air intake pipe 3 is fixedly connected to the tantalum-niobium smelting device. On the outlet pipe, an air pump 4 is installed at the upper end of the filter box 2, and ventilation pipes are installed at the left and right ends of the air pump 4. When the air pump 4 is turned on, the air pump 4 draws the exhaust gas into the filter box 2 through the air inlet pipe 3. A filter plate 5 is installed inside the filter box 2. The filter plate 5 can filter the residue mixed in the exhaust gas. A waste residue box 6 is placed at the bottom of the filter box 2. The residue is filtered by the filter plate 5 and then falls into the waste residue box 6. The waste residue box 6 is convenient for collecting waste residues, so as to improve the subsequent filtering effect of the exhaust gas.

[0024] An activated carbon adsorption plate 7 is installed above the filter plate 5. After the exhaust gas passes through the filter plate 5 to filter the residue, it continues to pass through the activated carbon adsorption plate 7. The activated carbon adsorption plate 7 can filter and adsorb organic matter in the exhaust gas, and play a role in removing odor. The filter plate 5 and the activated carbon adsorption plate 7 are fixedly installed with card plates on both sides. The left and right sides of the filter box 2 are provided with card slots. The box door on the front side of the filter box 2 is opened, and the filter plate 5 and the activated carbon adsorption plate 7 are pulled out from the card slots, which is convenient for disassembling the filter plate 5 and the activated carbon adsorption plate 7, and is convenient for replacing, repairing and cleaning the filter plate 5 and the activated carbon adsorption plate 7.

[0025] like Figure 2 and Figure 4 As shown, the vacuum pump 4 at the upper end of the filter box 2 continues to transport the exhaust gas to the spray box 8. The upper end and the left and right side walls of the spray box 8 are installed with spray pipes 9. After the exhaust gas enters the spray box 8, the spray pipe 9 is connected to the external water tank. The water pump transports the water in the water tank to the spray box 8 through the spray pipe 9. The surface of the spray pipe 9 is evenly spaced with nozzles to facilitate all-round spraying of the exhaust gas. The electric control valve inside the air duct on the right side of the spray box 8 is closed, allowing the exhaust gas to stay in the spray box 8, fully contacting and spraying the exhaust gas. The water sprayed by the nozzle absorbs acidic gases, reduces odors, and improves filtering and purification effects. A sewage pipe 10 is installed on the rear side of the spray box 8. After the exhaust gas is transported to the inside of the treatment box 12, the electric control valve in the sewage pipe 10 is opened to facilitate the discharge of waste water.

The interior of the treatment box 12 is filled with sodium hydroxide solution. The exhaust gas is filtered through the sodium hydroxide solution. Multiple filtration and purification can effectively remove the odor in the exhaust gas. A motor 13 is installed on the right side of the treatment box 12. The output end of the motor 13 is connected to a stirring shaft. A stirring rod 14 is installed on the surface of the stirring shaft. When the motor 13 is turned on, the motor 13 drives the stirring shaft and the stirring rod 14 to rotate, and the stirring rod 14 stirs the hydrogen and oxygen in the treatment box 12. The sodium chloride solution can fully mix and contact the exhaust gas to improve the purification effect. A monitor 18 is installed at the upper end of the inside of the treatment box 12. The monitor 18 can monitor the gas content of the exhaust gas in the treatment box 12. When the exhaust gas meets the standard, the monitor 18 controls the opening of the electric control valve in the exhaust pipe 17 on the right side of the treatment box 12 to facilitate exhaust. When the exhaust gas does not meet the standard, a circulation pipe 16 is installed on the rear side of the treatment box 12. The circulation pipe 16 is connected to the intake pipe 3. The monitor 18 controls the opening of the electric control valve in the circulation pipe 16. The exhaust gas is filtered and purified again through the circulation pipe 16 to prevent the exhaust gas that does not meet the standard from being discharged, polluting the environment and endangering human health.
