Venturi pressure difference and cleaning efficiency
Thread Content
Is a higher venturi pressure difference better for cleaning efficiency, or is a lower venturi pressure difference better? What are the hazards of being too large or too small? What should be the appropriate pressure difference for a normal venturi scrubber?
A large pressure difference results in better cleaning efficiency, with dust particles of small size being removed； Conversely, the dust particles are larger ； However, the pressure difference is high, requiring significant wind pressure and resulting in high energy consumption. The appropriate pressure difference should be selected based on the dust removal requirements.
It’s definitely better to have a slightly higher pressure difference; generally, around 110 to 135 KPA is sufficient
What would happen if there were no venturi?
This will probably clog the synthesizer scrubber tower and the flare pipeline; check the water quality
The Venturi pressure difference mainly depends on the flow rate of the spray water; if the flow rate is too low, the gas cleaning effect is poor, and structural issues may arise in the pipes, resulting in a higher pressure difference. When the flow rate is too high, the Venturi pressure difference decreases, but the system’s overall pressure difference increases. Therefore, it is necessary to consider various factors when making decisions. Another reason for high pressure difference is a clogged gauge!
