Energy - Saving Rotary Ash Cooler / Rotary System Strong Adaptability

Rotary system,Its material is 45,QT700-2 and Q235,for the Rotary Ash Cooler:

Origin: China

Brand: Qingdao Kechengyi

Introduction: the rotation system by the support ring, return wheel, etc, the roller support ring outside set drive roller driven by the driving mechanism on four return wheel rotation, through the adjustment of the return roller can realize drum height adjustment, to support ring wear roller after the height of the drop, catch wheel is limiting roller axial displacement.

General Introduction

The drum type ash cooler is a drum type heat exchanger used for cooling the bulk material, the structure and heat exchanging process of which are different from that of the usual heat exchanger. For the drum type ash cooler, three methods of heat transfer as thermal radiation, conduction, and convection are working in the same time, and primary cooling medium is water and the secondary is air. It is a high efficiency ash cooling equipment, which is designed to meet the requirement of the large-volume CFB boiler. The drum ash cooler consists of drum, ash filling device, ash discharge device, drive device, transmission device, cooling water system and electric control device, which is specifically used for the hot ash cooling of CFB boiler

Main Structure of the Rotary Ash Cooler:

Rotating system: it is composed of supporting ring, supporting wheel, and catch wheel. The supporting ring is installed in the outside of the drum, which is driven by the driving mechanism to push the drum rotating on the four supporting wheels. The height of the drum can be set by adjusting the supporting wheel. The catch wheel can limit the axial displacement of the drum.

Ash falling device: it is made up of manhole, expansion joint, ash falling pipe, ash tank, ash sealing device. The boiler bottom ash will fall into the drum of the ash cooler through the ash filling pipe. The ash tank has a negative-pressure sealing port. The ash sealing device can prevent the ash from leaking by the anti-spin action.

Ash discharge device: it is composed of ash outlet sealing cover and ash outlet, and installed with negative-pressure air port and ash discharge port. The sealing cover is made up of two removable parts (upper and lower parts), which is convenient for maintenance.
