Application:
Iron and steel industry bottom furnace directly restore iron.
Working principle:
high efficiency cylinder cooler series supporting steel industry bottom furnace direct reduction iron production process, 1100℃ high temperature pellet in the rotary cylinder with inclination and guide structure rotation, after spray cooling, from the feeding end to the discharge end, the pellet temperature reduced to below 300℃.
It is mainly composed of feeding device, cylinder body, support device, discharge device, transmission device, sealing device and efficient cooling. The base of rotary body part, transmission part and carrier support part is installed under a certain slope based on the working conditions
Cylinder part: adopts the new structure of two cylinders at both ends of the central single cylinder, the cooling unit adopts spray rapid cooling method in the cylinder space to realize the rapid, efficient and controllable scientific cooling;
Cooling system: including cooling cover, nozzle, pipe, exhaust chimney, cooling tower, water supply pump, suction pump, working platform etc.;
Main performance and features:
★ Designs different cooling atomization nozzle, and material gradient cooling in the cylinder to improve heat transfer efficiency:
Cylinder cooler cooling adopts the forced convection cooling of spray vaporization, and adjust the average diameter of Soda and droplet speed of atomization droplet according to the temperature gradient to improve the heat transfer efficiency;
★ The front and rear ends of adopt double-layer cylinder structure to effectively protect the cylinder and support and transmission devices, while increasing the heat transfer area: Special cooling nozzle is designed to cool the interlayer of the double layer cylinder, effectively protecting the support and transmission device, and increasing the heat transfer cooling area, making the structure more compact and reasonable.
★ Provides a variety of sealing methods to effectively prevent pellet oxidation and ensure product quality:
The combined sealing device of ceramic fiber cloth and nitrogen pressure is used between the inlet and discharging device and the rotating cylinder, and the outlet is also designed with double-layer nitrogen curtain seal.
★ Cylinder cooling machine is with compact structure, high design technical level, improve cooling efficiency and product quality, effective energy saving and reduce production cost.
