This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

An exhaust gas inlet pipe 3 is connected to the upper left side wall of the reaction chamber 1, and an exhaust fan 4 is installed on the exhaust gas inlet pipe 3. Multiple flow-damping plates 5 are arranged left and right inside the reaction chamber 1, dividing the interior into multiple reaction chambers.

[0022] The exhaust fan 4 is started to allow the exhaust gas to enter the reaction chamber 1 through the exhaust gas inlet pipe 3. The exhaust gas enters the middle of the reaction chamber 1 and flows through the flow port of the flow buffer 5 into multiple reaction chambers, which slows down the flow speed of the exhaust gas in the reaction chamber 1 and increases the residence time of the exhaust gas in the reaction chamber 1, ensuring that the exhaust gas and ammonia water react fully. The liquid pump 11 is started to extract and transport the ammonia water in the ammonia water tank 12, and input it into multiple spray pipes 6 through the diversion pipe 10. The ammonia water is sprayed into the reaction chamber 1 through the spray pipes 6 and the spray nozzles at the bottom of the spray branch pipes 8 to form a water curtain. The flow control valve 9 adjusts the flow rate into the spray pipes 6, so that the ammonia water sprayed from the spray nozzles gradually decreases from left to right to avoid waste. The drive shaft 18 rotates, which drives the rotating shaft 14 to rotate through the transmission bevel gears 19 and 16. The rotating shaft 14 drives multiple agitator blades 20 to rotate in the reaction chamber, agitating the exhaust gas, increasing the contact between the exhaust gas and ammonia water, ensuring the reaction effect, and improving the reaction efficiency.

[0025] The treated gas is input to the next step through the exhaust pipe 26 and the discharge pipe 24. The conveyor shaft 22 drives the spiral conveyor blade 23 to rotate, which can push out the liquid material at the bottom, speed up the discharge efficiency, and improve practicality. The drive motor 27 is started to drive the double-position transmission wheel 28 to rotate. The double-position transmission wheel 28 can drive the conveyor shaft 22 to rotate through the first transmission belt 30 and the first transmission wheel 29. At the same time, the double-position transmission wheel 28 drives the drive shaft 18 to rotate through the second transmission belt 32 and the second transmission wheel 31.

The first protective cover 33 and the second protective cover 34 can protect the transmission components to avoid jamming and ensure safety.

[0026] like Figures 1 to 6 As shown, this utility model discloses a desulfurization device for lime powder processing. During operation, the exhaust fan 4 is activated to allow waste gas to enter the reaction chamber 1 through the waste gas inlet pipe 3.
