Abstract

The invention discloses an ammonia flue gas mixing apparatus used in a stern exhaust gas processing system. The apparatus comprises an evaporator connected to an ammonia storing tank. The evaporator is connected to an ammonia gas buffering tank. The ammonia gas buffering tank communicates with a demister arranged between a flue gas outlet of a desulphurization apparatus and a gas-gas heat exchanger. The demister is connected to a cold end inlet of the gas-gas heat exchanger through a pipeline. The cold end inlet of the gas-gas heat exchanger is connected to an SCR denitrification apparatus, wherein non-uniform coefficient Cvucata of flue gas velocity on a first layer catalyst inlet interface in the SCR denitrification apparatus is smaller than 15%, the ammonia-nitrogen ratio non-uniform coefficient Cvrcata is smaller than 5%, the temperature difference is smaller than +-10K, and the temperature difference at the catalyst inlet interface in front of the SCR denitrification apparatus inlet is smaller than +-1K. The apparatus provided by the invention is characterized in reasonable structure, good working performance and low pollution.

Description
