The kiln company shares the control method of the ventilation volume of the chemical rotary kiln: the chemical rotary kiln is a necessary equipment for the chemical industry and industrial production, and the combustion of the materials in the equipment requires sufficient oxygen, and the oxygen is usually injected by ventilation To achieve, ventilation is one of the two material conditions reflected by combustion. Without the proper amount of oxygen for fuel combustion, the heat cannot be released and the appropriate temperature cannot be maintained. Therefore, controlling the amount of ventilation is a work that needs to be done. The following is a detailed introduction about the control of the amount of ventilation.
Under normal circumstances, when the ventilation volume is small, the oxygen supply is insufficient, the combustion speed is slowed down, and the heat consumption is increased; when the ventilation volume is large, the gas flow rate increases, the combustion decomposition time becomes shorter, the flue gas volume after combustion is large, and the heat consumption is high. This will affect the normal operation of the kiln. Therefore, the ventilation of the chemical rotary kiln should be controlled. The fan at the rear of the system runs steadily and exhausts, and the ventilation in the kiln and furnace is basically stable. However, there are also some factors that affect the amount of ventilation, such as the change in the resistance of the entire system, the temperature of the air entering the chemical rotary kiln, whether the system leaks air and whether the fan inlet is mixed with cold air, whether there is dust accumulation in the pipe, blockage whether the material is spread evenly, kiln, furnace Is there interference between the two systems? These factors will affect the ventilation of the kiln, so the ventilation must be adjusted and controlled in time. In response to the above influencing factors, the amount of ventilation should be adjusted and controlled in a targeted manner. When the temperature of the air entering the chemical rotary kiln changes, it needs to be controlled within an appropriate range. For the air leakage of the system and the mixing of cold air at the inlet of the fan, the system should be overhauled to find the location of the air leakage and deal with it. For pipeline accumulation of dust, blockage uneven spreading of materials, the pipeline needs to be cleaned in time. Evenly spreading material can solve the problem. For the interference of the two systems of kiln and furnace, the ventilation volume of the two systems can be adjusted and balanced by setting the kiln tail gate and flue shrinkage. If the total air volume of the whole system is too large, it is more convenient to adjust on the pipeline after the two systems meet.
In summary, we can understand that in order to control the ventilation of the chemical rotary kiln, it is necessary to accurately measure the amount of ventilation, which can be determined by observing the negative pressure of the ventilation inlet of a device. Under the premise of accurately measuring the amount of ventilation, controlling the amount of ventilation can give full play to the working capacity of the kiln. I hope that the content explained in this article will help everyone. The control of this equipment in terms of ventilation will also be more simple and easy to operate.
