[0014] In this invention, the exhaust gas undergoes a three-stage purification and filtration process: a settling chamber, a bag filter, and an alkaline spray tower. This removes cuprous chloride dust and chlorine gas from the exhaust gas. Alkaline solution covers the aeration pipes in the alkaline spray tower, and the dusty gas, after secondary purification, enters the alkaline spray tower through the aeration pipes, ensuring full contact between the dusty gas and the alkaline solution, thus improving purification efficiency. Both nozzles simultaneously spray alkaline solution to contact the dusty gas. The sprayed alkaline solution is then recovered to the alkaline spray tower for polymerization. In the alkali tank, pumps 1 and 2 simultaneously extract alkali solution to achieve alkali recovery and reduce resource waste. Buffer plates 1 and 2 restrict the flow of liquid from pump 1 into the alkali tank, while buffer plates 3 and 4 restrict the flow of liquid from pump 2 into the alkali tank. The recovered alkali solution in the tank settles impurities and falls into the slag discharge ring. During slag discharge, valve 2 opens and the dust and slag in the slag discharge ring are discharged through the slag discharge pipe. Attached Figure Description

[0028] Working Principle: Before operating the equipment, first check that the alkali spray tower 7, settling chamber 1, and bag filter 2 are unobstructed and in a fully functional state. First, open valve 21. The alkali solution enters the alkali tank 10 through the inlet pipe 11. When the alkali solution in the spray tower 7 reaches the required level, it triggers the level gauge 41, which in turn triggers valve 21 to close. Pumps 26 and 29 start simultaneously. Pump 26 draws the alkali solution from the tank 10 into the suction pipe 27. The alkali solution in suction pipe 27 is then pumped by pump 26 into suction pipe 31. The alkali solution in suction pipe 31 is then transported by pump 26 to spray pipe 16. The alkali solution in spray pipe 16 then flows through the spray pipe 16. The alkali solution is sprayed into the alkali spraying tower 7 through nozzle 17. Pump 29 starts to draw the alkali solution from the alkali tank 10 into the pumping pipe 30. The alkali solution in the pumping pipe 30 is then pumped into the pumping pipe 32 by pump 29. The alkali solution in the pumping pipe 32 is then transported to the spraying pipe 18 by pump 29. The alkali solution in the spraying pipe 18 is sprayed into the alkali spraying tower 7 through nozzle 19. Then, fan 5 starts. The cuprous chloride dust generated in the crushing and packaging processes is drawn by fan 5 into the settling chamber 1 through the inlet pipe 4. Larger dust particles in the settling chamber 1 settle naturally due to their own gravity and the action of the baffles. The obstruction of the baffle plate 33 creates a detour. To achieve better purification, larger dust particles naturally settle into the settling tank 34. The dusty gas undergoes its first purification in the settling chamber 1, and then enters the bag filter 2 for a second purification through the outlet pipe 3. The dusty gas entering the bag filter 2 then enters the fan 5 through the outlet pipe 26. The dusty gas in the fan 5 enters the alkaline spray tower 7 through the inlet pipe 28, and then enters the alkaline spray pipe 7 through the aeration pipe 20. The alkaline solution covers the aeration pipe 20, ensuring full contact between the dusty gas and the alkaline solution. The dusty gas rises within the alkaline spray pipe, and the alkaline solution sprayed by nozzles 17 and 19 comes into contact with the rising dusty gas for final purification. After purification... The gas is collected through the gas collecting ring 12, and the collected gas enters the exhaust pipe 14 and is discharged through the exhaust pipe 14. Water pump 1 26 and water pump 2 29 simultaneously draw alkaline solution from alkaline solution tank 10 to realize the recovery of alkaline solution and reduce resource waste. Buffer plate 1 37 and buffer plate 2 38 restrict the horizontal flow of liquid drawn from alkaline solution tank 10 by water pump 1 26. Buffer plate 3 39 and buffer plate 40 restrict the horizontal flow of liquid drawn from alkaline solution tank 10 by water pump 2 29. The recovered alkaline solution in alkaline solution tank 10 has impurities falling into the slag discharge ring 23 through sedimentation. When slag is discharged, valve 2 25 is opened and the dust and slag in the slag discharge ring 23 are discharged through the slag discharge pipe 24.
