Garbage furnace/ Cement Kiln treating industrial waste & urban garbage disposal technology and equipment/ Rotary kiln project

 

Jiangsu Pengfei Group self-developed rotary kiln calcination system, gained 2 patents in 2003, while in 2006 Pengfei Cement rotary kiln was approved as “Famous brand of Chinese Building Material Machinery Industry”, “Top brand of Jiangsu”, gained “China Top Brand” in 2007, based on this, Jiangsu Pengfei group, Southeast University and Yancheng Engineering Colleague developed Cement Kiln treating industrial waste & city waste technology, among this the development & integrative subject of intelligent control system of large rotary kiln and low temperature cogeneration was bear by Southeast University, the subject of cyclone preheater high efficient low resistance separating, and utilizing pre-calciner to burn the city waste was bear by Yancheng Engineering Colleague. This project should be used for energy-saving calcination for cement industry with high power consumption, and utilized the power of waste burning to be auxiliary heat source meanwhile it utilized the city waste, so implemented the circulating economy. This technology is mainly used in 5000tpd dry process clinker production line and it is also suitable for the energy-saving improvement on medium and small cement calcination system. The innovating points of this projects are:

①    Utilizes the double air outlet cyclone separator patent in cyclone preheater to reduce the resistance loss;

②    Creatively move the city waste burning inside of rotary kiln technology into the pre-calciner to burn the city waste, the suitable type is enlarged, waste quantity could be adjusted, calcining quality of rotary kiln is stable and pollution could be eliminated, waste heat source could be utilized, thus it implements circulating economy;

③    Creatively utilizes heat-resisting steel bars connect the internal liner of kiln body with high temperature insulation function in series to form the entire insulation layer, improves the rigidity of kiln body, reduces to become deformed and avoids the brick falling for red kiln;

④    For the external area of burning zone, developed circular heat exchanger patent technology, recycled the radiant heat of kiln body, reduced the heat loss of burning zone and saved the power consumption of cooler in external zone of burning zone;

⑤    Creatively raised the idea that utilized computer intelligent control system to completely optimize and integrate the five sections of large rotary kiln calcination: cyclone preheater, pre-calciner, coal powder burner, rotary kiln and cooler.
