Why is there internal combustion of the rotary dryer?
Sometimes, it may appear internal combustion in the process of operation for the rotary dryer, which will not only cause the panic of users, but also cause serious economic losses. So what are the causes of the internal combustion when the rotary dryer is running? Now let's analyze the source of the cause.
1,The volume of dryer is too small. If the volume of dryer is too small, but a large amount of materials must be dried, the water yield of materials will not meet the standard. The heat source device inside the dryer is not enough to dry the moisture of materials thoroughly. The user can only choose to increase the temperature of the heat source device by force. Finally, the materials can be dried. If he wants to increase the output, he can increase the heat source, The final result is combustion inside the drying drum. Therefore, if you really need a large number of drying materials, please choose a large type of drying equipment to process the materials.
2, Poor sealing of dryer.
If the dryer seal is not good, there will be combustion. Drying equipment is usually sealed to dry materials. If there is a problem with the sealing, it may be the design of the drying drum or excessive ventilation. There is a ventilation system inside the dryer. If the ventilation is too large, the fire inside the dryer will rise against the wind. If the fire is too large, the material inside the drum will burn, resulting in a large number of materials burned. Therefore, when the newly purchased drying equipment is tested, it is necessary to check the sealing condition and whether the installation conforms to the national standards. After the inspection, it is determined that the equipment has no quality problems before it can be used normally.
3, Drying materials cannot be discharged in time.
If the material in the dryer drum can not be discharged in time, it will also cause the material burning phenomenon. When the heat source in the dryer reaches a certain temperature, the moisture in the material will be pumped out. If the moisture content of the material is reduced to the minimum and cannot be sent out, the material will continue to absorb the heat source, and its temperature will be higher and higher. When the material absorbs a certain heat source and reaches the combustion point, the material will catch fire, which may lead to a big fire. Therefore, when drying materials, it is necessary to regularly check the inside of the dryer to see if the materials flow normally. If the flow speed is too slow, it is necessary to reduce the material supply and continue to supply when the materials flow normally. The above is the cause of the internal combustion of the dryer, I hope you can take preventive measures. Finally, I would like to remind you that once you find a fire inside the dryer, you should stop the dryer immediately, then stop the feeding, and start to put out the fire after the power failure.
