Title:
ROTARY LIME KILN PREHEATER WITH EFFICIENT FLUE GAS DESULFURIZATION
Document Type and Number:
WIPO Patent Application WO/2020/164259
Kind Code:
A1
Abstract:
The present invention relates to a rotary lime kiln preheater with efficient flue gas desulfurization, comprising a preheater main body, a top material bin, a material-feeding pipe, a flue gas-discharging pipe, a push rod device, and a material-feeding chute, and further comprising a conveying pipeline for a sulfur-fixing aid, wherein the conveying pipeline for a sulfur-fixing aid is provided with a nozzle at the lower end thereof, and the nozzle is located above the material-feeding chute. In the present invention, by providing the conveying pipeline for a sulfur-fixing aid, the sulfur-fixing agent aid powder can be conveyed to the nozzle above the material-feeding chute in the preheater main body through the conveying pipeline for a sulfur-fixing aid under the action of a high speed airflow, and can then be sprayed out via the nozzle for mixing with a high temperature flue gas stream from a rotary lime kiln, so as to improve the microstructure of a sulfur-fixing agent, and to delay the high temperature decomposition of a desulfuration product, thereby improving the decomposition temperature of the product.
