Description

Calciner convenient to dismantle and maintain

Technical Field

The utility model relates to the technical field of calciners, in particular to a calciner convenient to detach and maintain.

Background

The calciner is a thermal equipment for heat-treating raw materials of carbon (such as coke and anthracite) at high temperature so as to improve the performance of the raw materials. The equipment is used for iron making, rare metal recovery, catalyst production, environment improvement and special chemical product production.

The furnace type used for calcining the carbon materials at home and abroad mainly comprises a rotary kiln, a pot type calciner, a revolving bed calciner, an electric calciner, a coke oven and the like. These furnace types differ significantly in heat source, heat transfer mode and calcining atmosphere due to the difference in furnace structure and process conditions. The tank calciner and the coke oven are of the same type of indirect heating. The heat of the flue gas in the flue is transferred to the calcine through the refractory bricks as the flue wall. Rotary kiln and rotary bed calcination belong to another type of direct heating. The high-temperature flue gas is in direct contact with the calcined material, and the burning loss of the carbon is larger than that of the former type of heating which basically isolates air. The electric calciner takes the calcined material as a resistance heating element to convert electric energy into heat energy, thereby realizing self heating of the calcined material.

For example, in chinese patent 201220078692.8 (application date 2012.03.03, bulletin date 2012.10.24), a pot calciner is disclosed, the structure of the calciner is simple, the construction cost is low, the calcination quality is good, the volatile component decomposed from the raw material is discharged from the discharge outlet at the upper part of the calciner, and then mixed with air, and the mixture is preheated by a heating flame path and enters the heating flame path for full combustion and utilization, the whole calciner has higher heat efficiency and strong production continuity, but in the above patent technology, the components in each cavity are mostly in an integrated structure, so that the disassembly is inconvenient for maintenance, the maintenance is troublesome when the failure occurs, even the whole replacement is needed, and the maintenance cost is high.
