Embodiments of the invention involve the application of a disk-in-tube type of wet or dry ESP (electrostatic precipitation) technology for the capture/removal of airborne particles entering a gas turbine compressor. This provides an effective method of particulate removal without the inefficiencies associated with conventional filtering techniques. Embodiments of the innovative approach also eliminate the inlet airstream blocking effect of a conventional filter, thus making its use and operation adaptable to different operating environments and processes that require clean input air streams (including industrial manufacturing processes, power generators, combined turbine and fluid recapture systems for use in heating and cooling, etc.).

An electrical discharge type air cleaner is provided. The air cleaner includes a dust collecting tank accommodating liquid, a housing accommodating the dust collecting tank, an air supplying portion supplying air to the dust collecting tank, an air discharging portion discharging the air from the dust collecting tank and having an air discharging tube facing a surface of the liquid, a plurality of discharge electrodes disposed at the air discharging tube, a charging portion in the dust collecting tank, and a rotary vane forming a vortex in the liquid. The charging portion charges the liquid with a polarity opposite to a polarity of the discharge electrodes such that an electric field is formed between the discharge electrodes and the liquid and pollutants in the air are collected into the liquid. A distance between the surface of the liquid ad the discharge electrode is maintained within a predetermined distance range.

The present invention relates to the use of corrosion, temperature and spark resistant electrically conductive components in wet electrostatic precipitator systems (WESPs). In particular, the present invention is directed to using a conductive composite material in the fabrication of wet electrostatic precipitator system components.

Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The apparatus may include a housing having a chamber, at least one process gas inlet in fluid communication with the chamber, a process gas outlet spaced from the at least one process gas inlet and in fluid communication with the chamber, one or more ionizing electrodes in the housing and one or more collection electrodes or plates in the housing. The housing may be in fluid communication with a sealing liquid source, such as a water source. Sealing liquid is provided and introduced into the chamber in an amount sufficient to submerge the at least one process gas inlet and stop the flow of contaminated gas into the chamber.

An air purifier is disclosed having a bubble generator configured to generate fine air bubbles with a diameter of about 50 m or less and a negative electrical charge. The bubble generator is coupled to an air purification tank, which contains a liquid for purifying the air within the air bubbles, by dissolving impurities. The tank also has a positive electrode disposed within the liquid. The positive electrode is configured to attract the negatively charged air bubbles, thereby promoting defoaming and increasing the air throughput rate.

An apparatus and method for removing mercury from an incoming gas stream contaminated with mercury so as to deliver an outgoing gas stream free of the removed mercury introduces ozone into the gas stream to deposit mercury carried by the gas stream on separator elements so as to remove the deposited mercury from the gas stream. The deposited mercury is washed off of the separator elements, and the removed mercury is collected for further processing.

An electrostatic precipitator for introducing sub-millimeter sized particles into a carrier material. The carrier material has a melting point which lies above 0 C., preferably above room temperature. The electrostatic precipitator comprises a casing having an inlet for inserting a gas flow into the casing and having an outlet for guiding a gas flow out of the casing. A channel for passing the gas flow from the inlet to the outlet is provided. A discharge electrode is provided on a first side of the channel. A collecting electrode is provided at a second side of at least a part of the channel. The electrostatic precipitator applies an electric field between the discharge electrode and the collecting electrode. A receiving volume is provided with a molten material as carrier material.
