Conventionally, paint which does not adhere to work in spraying (hereinafter referred to as "paint mist") is collected while flowing at a high speed through a slit opening called venturi scrubber
in a mixture of air and water.
An analytical model using eddy diffusivity is applied for predicting droplet concentration distribution and liquid film formation in a Venturi scrubber
. By comparing experimental data of film formation reported in literature (Viswanathan et al., 1984) and the results obtained from this model, a semi-empirical correlation for liquid droplets eddy diffusivity is obtained.
removes airborne water-soluble organic dyes from manufacturing process.
Since the control technology upon which the standard is based is an ESP or high-efficiency scrubber, it was assumed that 40 percent of the lime kiln scrubbers would require an upgrade to a high-efficiency device, which was assumed to be a 138 kPa pressure drop venturi scrubber
. The energy consumption this represents was calculated from the energy use factors used to estimate the requirements under existing air rules, and an assumption that energy requirements are linearly proportional to the drop in pressure across the devices.
Sharp's design included two packed towers and a venturi scrubber
. Each tower is 24 inches in diameter and 5 feet long.
If heat recovery is in the form of hot process water, the waste heat boiler is not necessary and the venturi scrubber
is used; otherwise it is replaced by a cyclone.
Compliance Systems researchers found that some venturi scrubber
operators wished to fine-tune their pollution-control systems by changing the pressure drop.
Air pollution control is provided by a five-stage system consisting of a pre-cooler for exhaust gases, a condenser to remove moisture, a Venturi scrubber
and packed bed scrubber to remove particulate matter, and a thermal oil heater to destroy volatile organic compounds.
To accomplish this critical gas cleaning, ERG is supplying two specially designed high-pressure venturi scrubbers
to remove 99.5 per cent of particulates.
