Example Embodiment
[0013] Example 1
[0014] See figure 1 Because the solid waste has a high water content and a very fine particle size, in order to ensure the temperature in the environmental reduction smelting furnace, increase the gas permeability of the charge, and increase the bed energy rate, this part of the filter mud is input into the boiling heating furnace and the rotary kiln for drying. The drying temperature is 800℃, and then it is sent to the brick making machine through a belt conveyor to be pressed into a brick-shaped charge with a certain strength and particle size. The brick-shaped charge is a 240*115*53mm standard brick specification, which is used as an environmentally friendly reduction smelting furnace. Charge into the furnace. The heat source required for the drying of the rotary kiln comes from the combustion of the carbon fine powder produced during the carbon fine crushing process of the environmental reduction method production process. After drying, the moisture content ...

[0018] Example 2
[0019] See figure 1 Because the solid waste has a high water content and a very fine particle size, in order to ensure the environmental protection of the temperature in the reduction smelting furnace, increase the air permeability of the charge, and increase the bed energy rate, this part of the filter mud is input into the boiling heating furnace and the rotary kiln for drying. The drying temperature is 900℃, and then it is sent to the brick making machine by a belt conveyor to be pressed into a brick-shaped charge with a certain strength and granularity. The brick-shaped charge is a 240*115*53mm standard brick specification, which is used as an environmentally friendly reduction smelting furnace. Charge into the furnace. The heat source required for the drying of the rotary kiln comes from the combustion of the carbon powder produced during the carbon powder crushing process of the environmental reduction method production process. After drying, the moisture ...
