Cyclone Air Pollution Comtrol Equipment (Engineering SoundBites)
The walls of the cyclone narrow toward the bottom of the unit, allowing the particles to be collected in a hopper. The cleaner air leaves the cyclone through the top of the chamber, flowing upward in a spiral vortex, formed within a downward moving spiral. Cyclones are efficient in removing large particles but are not as efficient with smaller particles.

For this reason, they are used with other particulate control devices. Venturi Scrubbers Venturi scrubbers use a liquid stream to remove solid particles. In the venturi scrubber, gas laden with particulate matter passes through a short tube with flared ends and a constricted middle. This constriction causes the gas stream to speed up when the pressure is increased.
Cyclonic separation
The difference in velocity and pressure resulting from the constriction causes the particles and water to mix and combine. The reduced velocity at the expanded section of the throat allows the droplets of water containing the particles to drop out of the gas stream. Venturi scrubbers are effective in removing small particles, with removal efficiencies of up to 99 percent. One drawback of this device, however, is the production of wastewater.
Fabric filters, or baghouses, remove dust from a gas stream by passing the stream through a porous fabric. The fabric filter is efficient at removing fine particles and can exceed efficiencies of 99 percent in most applications.

The selection of the fiber material and fabric construction is important to baghouse performance. The fiber material from which the fabric is made must have adequate strength characteristics at the maximum gas temperature expected and adequate chemical compatibility with both the gas and the collected dust.
One disadvantage of the fabric filter is that high-temperature gases often have to be cooled before contacting the filter medium. Fabric filter baghouse components Electrostatic Precipitators ESPs An ESP is a particle control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates.

The ESP places electrical charges on the particles, causing them to be attracted to oppositely charged metal plates located in the precipitator. The particles are removed from the plates by "rapping" and collected in a hopper located below the unit. The removal efficiencies for ESPs are highly variable; however, for very small particles alone, the removal efficiency is about 99 percent.
Electrostatic precipitator components Control of gaseous pollutants from stationary sources The most common method for controlling gaseous pollutants is the addition of add-on control devices to recover or destroy a pollutant.
There are four commonly used control technologies for gaseous pollutants: Principles of controls, source control. Learning Objectives To make the student aware of effects of gaseous and particulate air pollutants on humans, plants and materials; principles of air pollution control and various control equipments at source.
Source Control Technology Air quality management sets the tools to control air pollutant emissions.
