Resistance of WESP in rotary kiln flue gas exhaust treatment and its influence?
Publish Time: 2024-12-18
Wet electrostatic precipitator (WESP) plays a vital role in rotary kiln flue gas exhaust treatment. It can effectively remove fine particles and harmful gases in flue gas, providing strong guarantee for environmental protection emission standards. However, WESP will generate certain resistance during operation, which has an important impact on the entire flue gas treatment system.
The resistance of WESP mainly comes from its internal electric field structure, flue gas flow channel, flushing system, and the design of dust collecting electrode and discharge electrode. These factors jointly determine the pressure loss of WESP when treating flue gas. Generally speaking, the resistance of WESP is between several hundred Pa and several thousand Pa, and the specific value depends on the specifications of the equipment, the temperature and flow rate of the treated flue gas and other factors.
The influence of WESP resistance on the rotary kiln flue gas treatment system is mainly manifested in the following aspects:
First, the increase in resistance will increase the workload of the fan, thereby increasing energy consumption. When the resistance of WESP is too high, the power consumption of the fan will increase significantly, resulting in an increase in the operating cost of the entire flue gas treatment system.
Secondly, too much resistance may also affect the flow rate of flue gas, causing the flue gas to stay too long inside the WESP, thereby increasing the contact time between the flue gas and the inside of the equipment, and aggravating the corrosion and wear of the equipment.
In addition, the resistance of WESP will also affect the ventilation effect of the system. If the resistance is too large, it may cause poor flue gas circulation, which in turn affects the normal operation of the rotary kiln.
Therefore, when designing and using WESP, it is necessary to fully consider the impact of its resistance on the system. By optimizing the equipment structure, improving the flushing system, and selecting suitable materials, the resistance of WESP can be reduced and the operating efficiency and stability of the entire flue gas treatment system can be improved. At the same time, regular maintenance and maintenance of WESP, cleaning the dust and dirt on the dust collecting electrode and the discharge electrode can also effectively reduce the resistance and extend the service life of the equipment.
In summary, the resistance of WESP in rotary kiln flue gas exhaust treatment is an issue that needs to be highly valued. Through reasonable equipment design and maintenance measures, the resistance can be reduced and the operating efficiency and environmental protection performance of the system can be improved.
