Venturi Scrubber Design

Integrates impaction, interception, and diffusion using single-droplet efficiency: [ \eta_d = \fracStk^2(Stk + 0.5)^2 \quad \text(impaction) + \textinterception term + \textdiffusion term (Pe number). ]

A standard venturi scrubber consists of three distinct sections that work together to clean the air. venturi scrubber design

A standard Venturi scrubber consists of three distinct sections (see Figure 1 conceptually): Gas VelocityTo effectively atomize the scrubbing liquid, gas

Pressure drop (ΔP) is the single most important operational parameter, typically ranging from 2 to 50 kPa. This model explicitly includes droplet size prediction via

Gas VelocityTo effectively atomize the scrubbing liquid, gas velocities in the throat typically range from 150 to 400 feet per second. If the velocity is too low, the droplets will be too large to capture sub-micron particles.

More refined, defines penetration ( P_t = 1 - \eta ): [ P_t = \exp\left( -\frac2 \rho_l Q_l \eta_d L_td_d \rho_g Q_g \right) ] Where ( L_t ) = throat length, ( \rho_l ) = liquid density. This model explicitly includes droplet size prediction via Nukiyama–Tanasawa or Boll’s droplet diameter correlation: [ d_d = \frac0.5 \sigma\rho_g v_t^2 + 0.15 \left( \fracQ_lQ_g \right)^1.5 ] (σ = surface tension).
