Title
(EN) Dust-laden flue gas classification purification waste heat recovery system and dedusting heat storage and exchange device
(ZH) 一种含尘烟气分级净化余热回收系统及除尘蓄换热装置
Abstract
(EN)
The invention discloses a dust-laden flue gas classification purification waste heat recovery system and a dedusting heat storage and exchange device. The dust-laden flue gas classification purification waste heat recovery system comprises a shell which is of an empty cuboid structure, and the middle part of the shell is provided with a separating plate; the shell is divided into an upper chamberand lower chamber by the separating plate; the waste heat recovery system is characterized in that the lower chamber is a flue gas channel, and the upper chamber is a cooling medium channel; the leftend of the flue gas channel is provided with a flue gas inlet, and the right end of the flue gas channel is provided with a flue gas outlet; the lower end of the flue gas channel is provided with a terraced cleanout door; the left end of the cooling medium channel is provided with a cooling medium outlet, and the right end of the cooling medium channel is provided with a first cooling medium inlet; the flue gas channel is internally provided with the dedusting heat storage and exchange device and an ash remover; the dedusting heat storage and exchange device is composed of a plurality of dedusting heat storage and exchange units arranged side by side transversely; each dedusting heat storage and exchange unit comprises a foam metal block, a filter screen and a plurality of three-dimensional ribbed heat pipe; and the waste heat recovery system can be widely applied to waste heat recovery of industrial flue gas.
