The invention discloses a combination 
melting furnace for treatment of 
arsenic soda 
slag and low-melting-point heavy-
metal containing waste residue. The combination 
melting furnace for the treatment of the 
arsenic soda 
slag and the low-melting-point heavy-
metal containing waste residue comprises an air-lock feeder, a 
rotary kiln, a vertical incinerator, a high-temperature 
flue gas chamber and a crushing discharging mechanism, the air-lock feeder is connected with the 
rotary kiln, the 
rotary kiln is connected with the vertical incinerator, the vertical incinerator is connected with the crushingdischarging mechanism, the high-temperature 
flue gas chamber covers the outer part of the rotary 
kiln, the cylindrical shell of the rotary 
kiln is connected with the two ends of the high-temperatureflue 
gas chamber and the 
machine shell of the vertical incinerator through sealing rings, after two stages of 
combustion process are conducted on materials through the rotary 
kiln and the vertical incinerator, high-temperature 
flue gas is discharged through the rotary kiln and an 
flue gas outlet of the high-temperature 
flue gas chamber, and complete 
combustion of the combusted 
slag is thoroughly achieved after through the action of the crushing discharging mechanism. The combination 
melting furnace for the treatment of the 
arsenic soda slag and the low-melting-point heavy-
metal containing waste residue serves as 
combustion equipment, the equipment structure is simple and unique, the operation is convenient, the cost is low, waste residue 
smelting is conducted on 
industrial waste residue containing low-melting-point heavy-metal such as the arsenic soda slag and 
sludge containing arsenic, mercury, lead, 
zinc, 
cadmium through the unique technology of two stages combination combustion, andthe combination melting furnace for the treatment of the arsenic soda slag and the low-melting-point heavy-metal containing waste residue is also suitable for pyrolytic 
incineration of waste materialcontaining organics.
