Hubei Puyang Zedong Chemical Co., Ltd. Both the pyrite calcined slag and the industrial waste heat power generation two projects passed the provincial certification recently and obtained the certification of comprehensive utilization of resources issued by the Provincial Development and Reform Commission. Pyrite-based acid production uses the contact acid production process, which produces 0.7-0.75 tons of calcined slag per ton of sulphuric acid in the production process. Each year in the production of sulphuric acid, 226,500-300,000 tons of sulphur are produced due to pyrite roasting. The iron ore calcined slag contains about 56% iron. They recycled the pyrite calcined slag, and obtained comprehensive utilization of concentrate concentrate powder of 262,500 to 300,000 tons/year for steel plants as raw materials for steelmaking and cement plants as additives, which enabled the reuse of resources.
The device has the following characteristics:
1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.
2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.
3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.
4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.
5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment
6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.
Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
