Notes of the bag filter dust collectors during operation

The operation of the bag filter can be divided into a trial operation period and a daily operation period. Pay attention to the impact of changes in the load on the host equipment on the performance of the precipitator. After the machine is started, pay close attention to the working condition of the bag filter and make relevant records. In daily operation, the necessary inspections should still be carried out, especially the inspection of the performance of the bag filter.
In the trial run of the new bag filter, special attention should be paid to the following points:
1. The direction of rotation, speed, bearing vibration and temperature of the fan. A single component is inspected and then adapted for operation, and 2. The air volume and pressure and temperature at each test point are consistent with the design.
3. The installation situation of the filter bag, whether there is any bag drop, loose mouth, wear and the like after use, can be judged by visual inspection of the chimney discharge after commissioning.
4. Pay attention to whether the condensation in the bag room exists and whether the ash discharge system is unblocked. Prevent clogging and corrosion from occurring, and the accumulation of ash will affect the production of the host. Part of the performance test. In daily operation, adjustments must be made to the cleaning cycle and cleaning time. This work is an important factor in the performance of the dust collection and operation. If the cleaning time is too long, the dust layer will be removed and become a cause of leakage and breakage of the filter bag.
If the cleaning time is too short and the dust on the filter bag has not been cleared, the filtration operation will be resumed, and the resistance will be quickly restored and gradually increased, eventually affecting the use effect. The two cleaning time intervals are called the cleaning cycle, and it is generally desirable to have the cleaning cycle as long as possible, so that the dust collector can operate under economical resistance conditions. Therefore, it is necessary to carefully study the dust properties, dust concentration, etc., and determine the cleaning cycle and time according to different cleaning methods, and adjust to achieve better cleaning parameters during the test run.
At the beginning of the operation, there are often some unexpected situations, for example, abnormal temperature, pressure, moisture, etc. will cause damage to the new device. Part of the performance test. In daily operation, abrupt changes in the temperature of the required gas should still occur, which may cause deformation of the fan shaft, resulting in an unbalanced state, and vibration may occur during operation. Once stopped, the temperature drops sharply and vibrations are generated again when restarted. It is best to use different types of fans depending on the gas temperature.
