What matters should be paid attention to when the wet electrostatic precipitator is tested
In recent years, environmental protection has been in the hands of various stakeholders, especially in the management of the atmosphere. The operation of wet electrostatic precipitator can be divided into trial operation and normal operation. Before the test run, it is necessary to finish the inspection of various parts of the system, and then conduct the compliant operation, and conduct the functional test of the parts. In normal operation, it is necessary to pay attention to the host equipment load change will affect the function of the dust collector. Before mechanical start, should pay close attention to the condition of wet electrostatic precipitator, make relevant records.
1. Torsional deflection, rotating speed, bearing vibration and temperature of the fan.
2. Whether the air volume and pressure and temperature at each test point can be in accordance with the plan.
3. The device environment of the filter bag can present the environment of bag dropping, looseness, abrasion, etc. after application. The operation can be concluded by the exhaust environment of the chimney.
4. Pay attention to whether the bag room dew environment can exist and whether the ash discharge system can be used. Avoid the occurrence of infarction and corruption, ash accumulation will affect the main machine of wet electrostatic precipitator.
5. The dust cleaning cycle and the conditioning of the ash cleaning time, this matter is due to your dust collection function and operation status. Soot cleaning time is too long, will make the adherent dust layer was clear to fall off, become a filter bag leakage and damage because of reason, if the soot cleaning time is too short, to fall on the filter bag dust is not yet clear, just return to filter the lessons, will make wet electrostatic precipitator resistance increased soon return and homes, doing heavy influence its application results.
The time distance between two times of ash removal is called ash removal cycle, and it is expected to be as long as possible. Dust is, it is necessary to temper, dust concentration and other end of the discussion of solemn and resolution according to differences of ash removal method and soot cleaning cycle time, and at the end of the test run of the dispensing reach better slag discharge parameters.
In the beginning of the operation of the wet electrostatic precipitator, it will often present some unexpected environment, such as the appearance of very high temperature, pressure, moisture, etc. to the formation of new device infringement. A sharp change in the temperature of the gas will cause the shaft of the fan to deform, creating an unbalanced condition, and vibration will occur during operation. Once the operation is finished, the temperature drops sharply and the vibration will occur again when the new start is started. Different types of fan are best chosen according to the gas temperature.
Equipment test run of interests, can directly affect whether wrong operation, such as improper disposal, wet electrostatic precipitator are likely to soon lost efficacy, is, well equipped test run must be carefully and seriously.
