Infrared tunnel furnace for desulfurization waste liquid, infrared tunnel furnace package vertical furnace body, the top of the furnace body is provided with a desulfurization waste liquid atomizer and a hot air inlet, the lower part of the furnace body is provided with an overhead port for desulfurization tail gas, and the bottom of the overhead port for desulfurization tail gas is provided. There is a cool wind volute, and the bottom of the furnace body is provided with an ash discharge valve; the inner wall of the furnace body is provided with a carbon fiber jacket, and the side wall of the furnace body is also provided with a manhole and an inquiry window. A layer of quartz or mica sheets sandwiched between two layers of carbon fiber cloth. The desulfurization waste liquid infrared tunnel furnace has the characteristics of simple layout, convenient application, good corrosion resistance, good heat preservation effect, and no secondary pollution of waste water. Among them, the corrosion resistance is good, and the carbon fiber jacket is added to the inner wall of the furnace. The carbon fiber material has the characteristics of corrosion resistance, high temperature resistance, light weight and thin thickness.

The refractory infrared tunnel furnace body has an air inlet hole at the center of the top of the furnace body. The air inlet hole is the same as one end of the one-way airflow valve. The other end of the one-way airflow valve is connected to a heating box. There is a heating wire, the other end of the heating box is the same as the air outlet of the exhaust fan, the air inlet of the exhaust fan is the same as the refrigerant outlet of the heat exchanger, the refrigerant inlet of the heat exchanger is connected with an air intake pipe, and the heat medium outlet of the heat exchanger is connected There is a condensing box, the other end of the condensing box is connected with an exhaust pipe, the heat medium inlet of the heat exchanger is the same as the air inlet of the second exhaust fan, and the air outlet of the second exhaust fan is connected with a three-way air flow valve. There are exhaust holes in the center. It has the characteristics of environmental protection, low cost and good cooling effect.

Infrared tunnel furnace for copper powder extraction, feeding port, feeding pipe, infrared tunnel furnace, second infrared tunnel furnace, bracket, cooling section, second cooling section, third cooling section, servo motor, modified scraper, discharge pipe, The discharge port, the funnel, the automatic wheel, the driven wheel, the conveyor belt and the sealing gasket, and the top of the feeding port is constantly connected with a feeding pipe. Two infrared tunnel furnaces with different temperatures can dry the inhaled copper powder in different stages, and the three cooling sections equipped can quickly cool the copper powder without affecting the environment due to the emission of hot air. , and the modified scraper equipped in the second cooling section can transport the copper powder from the surface where it falls into the conveyor belt through the funnel. It does not need to make a large part of the discharge port overhead to make the dust fly, and it is reasonable and convenient to use. .
