Boiler water curtain dust removal
Thread Content
For boiler water curtain dust removal tanks, how can the ash inside be easily separated and cleaned?
We tried to pump it out directly using a slurry pump for filtration; the operating load on the plate and frame filter is quite high
Before the water curtain dust removal device, a dry gas-solid dynamic separation unit with high operating efficiency and low operating costs needs to be installed in the boiler flue gases; for example, a multi-factor cyclone mother-son gas-solid separation unit can be used to remove the majority of the dust contained in the flue gases in advance； Let the extremely small amount of dust that escapes go through the water curtain dust collector for further treatment. Otherwise, when a large amount of dust enters the washing water, the costs associated with subsequent solid-liquid separation remain high.
In this case, large-scale clarification tanks are required, or the water in the water curtain dust removal tank must be replaced, which leads to water waste and pollution
