How to Deal with Waste Gas Produced by Rotary Kiln

Published 2021/3/5 9:54:42

During the operation of the rotary kiln, exhaust gas will be produced. The production of exhaust gas will cause serious pollution to our living environment and air. However, the fuel used in the rotary kiln will produce a large amount of exhaust gas, which will affect the air when discharged into the air. Quality causes serious harm, so the treatment of exhaust gas becomes particularly important.
The rotary kiln uses the circulating fan control system and the exhaust gas treatment system to process the exhaust gas. The circulating fan can increase the heat utilization rate in the kiln and improve the temperature uniformity in the furnace. The heating section and constant temperature section of the kiln body are equipped with multiple sets of circulating fans, each circulating The fans work independently and do not interfere with each other. Each temperature zone is equipped with partitions to make it an independent heating and constant temperature zone, which reduces mutual interference and is convenient for flexible adjustment. The cooling section of the same type is equipped with cold air fans, and all circulating fans are performed by multiple inverters. Control and adjust the speed.
   In addition, an exhaust gas discharge pipe is installed at the front end of the rotary kiln body, and a plug-in plate regulating valve is installed in the pipe to adjust the exhaust gas flow. The exhaust gas and the heat treatment powder move in the opposite direction, and the waste heat is used to achieve a certain energy saving effect. The whole set of equipment is composed of three parts: furnace body, transmission system and temperature control system. Therefore, in the whole production process, in order to prevent environmental pollution, except for waste gas treatment, it does not directly use refractory in the internal rotary kiln furnace. Fiber to prevent the high-temperature crystallization and pulverization of refractory fibers from polluting the powdered heat-treated products. Therefore, the treatment of waste gas is inseparable from the cooperation of multiple systems. If the waste gas after the production of the externally heated rotary kiln is directly discharged, it will cause unfavorable conditions for our surrounding environment.
In order to reduce the emission of exhaust gas, the equipment uses a circulating fan to process the exhaust gas. It can operate independently to reduce interference between the equipment. In addition, the exhaust gas discharge pipe is installed according to the installation, which can reduce the pollution to the surrounding environment when the exhaust gas is processed. , Improve the efficiency of the equipment.
