洞道式干燥器烘干湿法铁红

DRYING WET-PROCESS IRON RED BY CHANNEL OVEN

介绍了采用硫酸生产过程中产生的废热空气通过洞道式干燥器烘干湿法铁红，着重介绍了该干燥器的结构、干燥原理及热风量控制。讨论了洞道式干燥器的长度、宽度、高度的选择，热空气进入方式和排气口的设置，以提高其热空气的利用率。

A drying technology for wet-process iron red by channel oven with the waste hot air during the production of sulfate process has been described, focusing on the structure of the oven, drying principle and control of hot air. This paper discussed the selection of the size(length,width and height) of the oven,the inlet mode of the hot air and the design of outlet to increase the utilization efficiency.
