The vertical cooler is a vertical cooling device developed by Henan Zheng Mining Machinery Co., Ltd. on the basis of introducing and absorbing foreign advanced technology for cooling high-temperature clinker. It has the characteristics of high heat exchange efficiency, fewer wearing parts, and no exhaust gas. It is suitable for the configuration of terrain height difference, and can be used in the calcination system of building materials, chemical industry and other industries. This type of equipment can significantly increase the temperature of the secondary air entering the kiln and play a role in energy saving and consumption reduction. It is an energy-saving and environmentally-friendly product.
Its working principle is mainly:
The materials calcined by the rotary kiln fall from the kiln head into the shell with castable lining. The burned or agglomerated materials larger than 100mm are stored on the upper part of the grate, and are discharged by the dumper at regular intervals; the materials that can pass through the grate fall Into the main body of the cooler, when the material is falling, the natural air blown by the centrifugal blower into the lower cooler moves upwards through the main cooling air caps of the upper and lower air chambers and the four compartment air caps to cool the materials; the air changes from natural air to hot air and enters the rotation The auxiliary fuel combustion in the kiln achieves the purpose of making full use of the waste heat. After the material has been stored in the cooler body for a period of time, when the temperature of the material drops to about 60°C higher than the normal temperature, the central control system outputs a signal to start the four electromagnetic vibrating feeders at the bottom of the feeding pipe connected to the cooler body. , And then unload the cooled material.
The vertical cooler is especially suitable for cooling large pieces of materials after calcination. It can effectively improve the thermal efficiency of the rotary kiln, reduce the heat consumption by more than 30%, and effectively reduce the fuel cost.
