Flash dryer is a kind of non-standard equipment widely used in chemical, pharmaceutical and other industries, and some abnormal situations may occur during its operation. In order to ensure the normal operation of equipment and production safety, we need to understand these anomalies and take corresponding countermeasures.
1. The gas inlet temperature is abnormal.
The gas inlet temperature is one of the important parameters of the flash dryer, which affects the drying efficiency and product quality. When the gas inlet temperature is too high or too low, it may cause the material to dry unevenly or the product quality to deteriorate.
Countermeasures: Adjust the feeding speed: Adjust the feeding speed appropriately according to the change of gas inlet temperature to maintain a stable temperature.
Check the heating system: check whether the heating system is working properly, and repair it in time if there is a fault.
Adjust the operating parameters: adjust the operating parameters according to the actual situation, such as inlet air temperature, outlet air temperature, etc., to adapt to different materials and production requirements.
2. The temperature of the air inlet of the dryer is abnormal.
Dryer inlet temperatures that are too high or too low may affect drying efficiency and product quality.
Countermeasures: Check whether the temperature sensor of the air inlet is working normally, and replace it in time if there is a failure.
Adjust the inlet temperature control valve to maintain a stable inlet temperature.
Check whether the heating system is working properly, and repair it in time if there is a fault.
3. The natural gas powder at the outlet of the bag dust collector is abnormal.
Excessive gas powder at the outlet of the bag collector can be caused by equipment failure or improper operation.
Countermeasures: Check whether the bag dust collector is working normally, and repair it in time if there is a failure.
Adjust operating parameters such as inlet air speed, filter air speed, etc., to reduce the generation of natural gas powder.
Clean the bag collector regularly to keep the equipment clean.
Fourth, the system pressure is abnormal.
A sudden increase or decrease in system pressure can be caused by equipment failure or improper operation.
Countermeasures: Check whether the system pressure sensor is working normally, and replace it in time if there is a failure.
Adjust the system pressure control valve to maintain a stable system pressure.
Check the equipment for leaks or blockages, and deal with them in a timely manner.
Regularly maintain and maintain the equipment to ensure the normal operation of the equipment and extend the service life.
Establish a sound production management system and operating procedures to ensure the safety and stability of the production process.
In short, in order to ensure the normal operation and production safety of the flash dryer for phenylglycine, we need to understand the operating principle of the equipment and the countermeasures for common failures. At the same time, it is also very important to strengthen the maintenance and maintenance of equipment. Through reasonable operation and maintenance, the service life of the equipment can be extended and the production efficiency can be improved.
