A double-hearth kiln and hot blast furnace air mixing system

Abstract

The utility model discloses a kind of double-chamber kiln and hot blast stove airflow mixing system, the double-chamber kiln and hot blast stove airflow mixing system, comprising: hot blast stove, one end of hot blast stove is connected with the backflow pipe of flue gas circulation, another end of hot blast stove is sequentially connected with coal mill, circulating fan and coal dust collector by pipeline, coal dust collector is communicated with backflow pipe, backflow pipe is equipped with first switch valve and thermometer, first switch valve and thermometer are connected with control module;Double-chamber kiln, double-chamber kiln has the passage for conveying high-temperature airflow, passage is connected with air supply pipe, one end of air supply pipe is communicated backflow pipe, the input end of air supply pipe is located between first switch valve and thermometer, air supply pipe is equipped with the second switch valve connected with control module.The double-chamber kiln and hot blast stove airflow mixing system of above structure can mix and match with the passage airflow of double-chamber kiln and circulating flue gas, so as to reduce the moisture content in circulating flue gas, and can reduce the output energy consumption of hot blast stove combustion fan.
