7010 is used in many applications to provide efficiencies as high as 99% or more in a single stage system The Apollo Series™ venturi scrubbers can be operated in a batch process or completely automated with a full array of control options to meet your specific needs. 0000098360 00000 n
The scrubber is a Venturi scrubber designed to recirculate water to remove fumes from a gas stream. As the inlet stream enters the throat, its velocity increases greatly, atomizing and turbulently mixing with any liquid present. throat length is calculated to be 2.5 meters, isn't it on higher side a bit? Solving for water to gas volume ratio. 0000053966 00000 n

These changes can be used to measure the flowrate of the fluid. However, increasing the throat velocity beyond a certain value does not increase the collection efficiency. 0000133408 00000 n
Absorption of fumes is achieved in the spray venturi … 0000020793 00000 n
A venturi tube can also be used to mix a liquid with a gas and siphon into the venturi flow. Wet scrubbers are smaller and more compact than baghouses or ESPs. 0000065781 00000 n
It is common in wet scrubber terminology to express the liquid flow as a function of the gas flow rate that is being treated. k = correlation coefficient whose value depends on system geometry and operating conditions (typically 0.1-0.2) R = liquid-to-gas ratio, m 3 /1000 m 3. ψ = inertial impaction parameter, dimensionless. Generally for well designed scrubbers the collection efficiency is >98%. venturi scrubbers to 40-60% (or lower) for simple spray towers [1]. The gas instead meets the concentrated scrubber formula inside the throat system. 0000007306 00000 n

Great Northern Paper Co., in Millinocket, Maine, uses venturi scrubbers to obtain the greatest sulfur dioxide removal efficiency The Great Northern Paper Co.’s mill in Millinocket, Maine, produces about 500,000 tpy of paper for telephone directories, magazines, almanacs, business forms, catalogs, and school workbooks. Increase in Liquid-to-gas Ratios ® increases the collection efficiency. The scrubbing liquid, most commonly water, comes into contact with the particulate laden gas stream in a highly turbulent, high-velocity venturi throat.

This is commonly called the liquid-to-gas ratio (L/G ratio) and uses the units of gallons per 1,000 actual cubic feet or litres per cubic metre (L/m 3). Collection efficiency depends on the following factors: 1. Monroe Environmental Venturi Particulate Air Scrubbers will often be integrated into a larger treatment system that includes a variety of processes including cyclonic separators, Packed Tower Scrubbers, filters, etc. 0000090294 00000 n
For all other systems, dimension "Sep. C 4" represents the overall height. 2 When there is a high percentage of fine particulate under 1 micron, the pressure drop and energy requirements becomes very large for efficient collection using a venturi. I am doing my BE project in Ventury scrubber design.As i am from Mechanical background,i have very less info.about this.So if you have previously done excel sheet/pdf of ventury scrubber design then that is very helpfull for me and that gives exact direction to my project work.
