Flue gas dust removal methods for flue gas desulfurization
Thread Content
Flue gas dust removal methods for flue gas desulfurization: 1. Bag filter dust removal; 2. Electrostatic dust removal; 3. Washing inside the desulfurization tower
For desulfurization tower washing, bag filters or electrostatic precipitators are generally used in boilers.
If the dust concentration in the flue gas is high during washing in the desulfurization tower and the emissions exceed the allowed limits, how should this be dealt with?
If it is not due to issues with equipment such as cyclones, the water injection volume and the water circulation rate in the filtration module can be increased.
Actually, this situation is inevitable; in my opinion, the most important prerequisite is for a system to operate stably, and then a positive feedback loop is established!
The key lies in the process operations: increasing the slurry circulation rate and raising the water injection volume. What should be done with the wet agent that has been washed out?
The washed slurry proceeds to further processing, and after the sludge cake is pressed out using a filter press, it is treated as hazardous waste
In the case of the Berg EDV process, upgrades can be carried out to address the issue of excessive flue gas dust levels; that is, upgrading from 5000 to 6000. Those who are familiar with this should understand what’s meant.
What is your current control level for smoke and dust emissions? Is it 30 or 50?
