而回转窑是一种大型密封式物料的煅烧设备，窑头窑尾密封装置能够有效减少废

The rotary kiln is a large-scale sealed material calcining equipment. The kiln head and kiln tail sealing device can effectively reduce the amount of waste gas, can control the excess air coefficient of the entire system, and reduce the system air leakage. The sealing effect of the kiln head and kiln tail is poor, which will affect the normal calcination of the materials in the rotary kiln, thereby reducing the quality and quality of the clinker. A large amount of cold air leaks into the kiln of the rotary kiln, reducing the amount of secondary air entering the kiln from the clinker cooler, thereby reducing the temperature of the secondary air, which is not conducive to cooling the material, but also reduces the temperature of the flame , Which affects the burning speed of clinker in rotary kiln and increases heat loss. Because the working environment where the kiln tail of the rotary kiln is located is relatively large, if the sealing effect of the kiln tail sealing device is not good, a large amount of cold air will be sucked in and a large amount of exhaust gas will be generated. The gas in the rotary kiln cannot be discharged, the fuel cannot be completely burned, and heat will be generated. The thermal system is destroyed, which increases the fuel consumption, power consumption and the load of the exhaust fan. It also reduces the output of the kiln and affects the electricity collection. Dust safety and efficiency.

The rotary kiln is a large-scale sealing material calcination equipment, kiln tail sealing device can effectively reduce the amount of exhaust gas, can control the whole system of excess air coefficient, reduce the system leakage. The poor sealing effect of the kiln tail will affect the normal calcination of the material in the rotary kiln, thereby reducing the quality and quality of the clinker. A large number of cold air leaked into the kiln, reducing the amount of secondary air from the clinker cooler into the kiln, thereby reducing the temperature of the secondary air, which is not only not conducive to the cooling material, but also reduces the temperature of the flame, affecting the kiln clinker combustion speed, increased the heat loss. Because the working environment at the end of the rotary kiln is large, if the kiln tail sealing device sealing effect is not good, will inhale a large amount of cold air, and produce a large number of exhaust gases. The gas in the rotary kiln cannot be discharged, the fuel can not be fully burned, and heat can be generated, the thermal system is destroyed, increasing the consumption of fuel, electricity consumption and the load of the exhaust fan, but also reduce the output of the kiln, affecting the safety and efficiency of the electricity collection and dust.

Because the negative pressure of the working environment at the end of the rotary kiln is large, if the sealing effect of the sealing device at the end of the kiln is not good, a lot of cold air will be inhaled and a lot of waste gas will be produced. The gas in the rotary kiln can not be discharged, the fuel can not be completely burned, and heat will be generated, the thermal system will be damaged, increasing the fuel consumption, power consumption and the load of exhaust fan, and also reducing the output of the kiln, affecting the safety and efficiency of electric dust collection.<br>
