The conditioning tower is used to reduce the temperature and to increase the moisture level of the gas, before it is passed through the dedusting equipment. It is called a conditioning tower because it conditions the hot gas, thus making it more suitable for the dedusting equipment to extract dust from it.
A hybrid filter system has been developed as an air pollution control device that closely integrates electrostatic precipitation (ESP) and fabric filter technologies into a durable, cost-effective device that produces superior filtration results. Its design uses a synergy between these two technologies whereby the filter bags are able to operate at high air-to-cloth (A/C) ratios than conventional pulse jet fabric filters.
Electrostatic precipitators have been used in many industries; several examples are cement, steel, aluminum, copper, ceramic, tile, petrochemical and power plant. An electrostatic precipitator is a large, industrial emission-control unit. They can handle large gas volumes with a wide range of inlet temperatures, pressures, dust volumes, and acid gas conditions.
The primary function of a cyclone is to separate dust from a gas stream. After separation, the dust discharges out the bottom of the cyclone and air discharges through the top exhaust. Cyclones (or centrifugal collectors) create a ‘cyclonic’ or centrifugal force, similar to water going down a drain, to separate dust from the polluted air stream.
