When the bag type dust removal accessories start to operate, some unpredictable situations often occur. For example, abnormal temperature, pressure, moisture, etc. will damage the new device. It is best to use different types of fans depending on the gas temperature. The quality of the equipment commissioning will directly affect whether it can be put into normal operation. If improper handling is performed, the bag filter may very quickly lose its effectiveness. Therefore, the commissioning of the equipment must be careful and prudent. During the trial operation of the new bag filter, special attention should be paid to checking the following points:
1,. Pay attention to the presence of dew condensation in the bag room and whether the ash discharge system is unblocked. Prevent clogging and erosion from happening, and when the accumulation of dust is severe, it will affect the production of the host.
2. The adjustment of the cleaning cycle and cleaning time is an important factor in the function and operation of the dust collector.
3, fan rotation direction, speed, bearing vibration and temperature
4. If the filter bag is installed, whether it is out of bag, loose or worn after use, it can be judged by visually observing the emission of the chimney after being put into operation.
5. Whether the processing air volume and the pressure and temperature of each test point are consistent with the design. If the cleaning time is too long, the attached dust layer will be washed off and become the cause of leakage and damage of the filter bag. If the cleaning time is too short and the dust on the filter bag has not been cleared, filtration work will be resumed, and the resistance will be quickly restored and gradually increased, ultimately affecting its use. The distance between the two cleanings is called the cleaning cycle. Generally, the cleaning cycle is as long as possible, so that the precipitator can operate under the premise of economic resistance. Therefore, it is necessary to carefully study the nature of dust, dust concentration, etc., and determine the cleaning cycle and time according to different methods of cleaning, and adjust the test to achieve better cleaning parameters. Dramatic changes in the gas temperature of the dust removal fittings can cause deformation of the fan shaft, resulting in an unbalanced state and vibrations in operation. Once at rest, the temperature drops sharply, and when it restarts, it will vibrate again.
