Problems solved by technology

This process requires the heat pipe heat exchange module and the superheater to be installed in the large flue of the sintering machine. Due to the large amount of dust in the flue, the heat pipe is prone to wear and burst, resulting in a greatly reduced heat transfer efficiency and even sintering shutdown.

Abstract

The invention discloses a waste heat recovery device and recovery method of a stepping type sintering machine. High-temperature wind in a sintering section flue and a cooling section flue is intercepted by the waste heat recovery device to conduct heat exchanging, so that full waste heat recovery is realized, heat-exchanged low-temperature wind is sent back into the sintering section flue and the cooling section flue, and the normal working of the stepping type flat-burning sintering machine is not affected.

Description

technical field [0001] The invention relates to a waste heat recovery device and a recovery method of a walking type flat sintering sintering machine. Background technique [0002] At present, sintering waste heat recovery is divided into two categories: on-machine waste heat recovery and off-machine waste heat recovery. Among them, on-board waste heat recovery mainly refers to recovery of waste heat from flat combustion. The waste heat recovery under the machine mainly includes the waste heat recovery of the sintering ring cooler and the waste heat recovery of the sintering belt cooler. [0003] There are few waste heat recovery and utilization methods of flat sintering, mainly including the composite waste heat recovery and utilization process of stepping flat sintering sintering machine, flue type heat pipe waste heat recovery process, etc. [0004] The composite waste heat recovery and utilization process of the stepping flat sintering sintering machine is to install t...
