Disclosed herein is an electrostatic precipitator apparatus that includes a housing having an inlet, into which gas is introduced, and an outlet from which the gas is discharged, and a collection module installed in the housing. The collection module includes a plurality of discharge electrodes, to which a voltage is applied, and a plurality of collection electrodes grounded and disposed between the discharge electrodes. The apparatus further comprises a washing water feeder to spray washing water to the collection module, and a washing water treatment device disposed beneath the collection module to accommodate the washing water dropped from the collection module.

A pollution control system for removing particle and gas phase pollutants in a waste airstream exhausted from commercial cooking operations may include a plurality of filters arranged within a housing for filtering particle and gas phase pollutants in the waste airstream. Various ones of the filters may be composed of a variety of different materials, and ozone may be provided within the housing to assist with removal of the pollutants. In some examples, a wash mechanism may be included to wash surfaces of a filter to remove grease therefrom. In some examples, the system may further include means to spray droplets (such as in a fog or mist form) into the waste airstream to condense a portion of gas phase pollutants into condensed particles.

Known wet electrostatic precipitators are large and inefficient. The present invention enables the production of smaller, more efficient and long lasting wet electrostatic precipitators by the addition of a central bore in the inner electrode through which a first purge flow is passed and directed into the precipitator chamber, perpendicular to the direction of flow of the gas to be treated through the chamber to urge the particulate into the water curtain. A second, larger, cleaning purge flow is also provided to disturb the water curtain such that it cleans the inner electrode of any deposited particulate.

A fluid processing system and method of processing a fluid includes a tank having an outer wall, a heating element, and an insulating element. The heating element is situated within the tank and includes a first electrode and a second electrode. The insulating element is positioned between the first electrode and the second electrode. As such, powering the heating element directs an electric current through the fluid within the tank for heating the fluid, while the insulating element provides electrical and thermal insulation to the outer wall of the tank.

A precipitation tube and a precipitation tube bundle for a wet electrostatic precipitator, in particular for separating dusts, gases, and/or aerosols from exhaust gases are disclosed. The precipitation tube is designed as a modular tube system. It has at least two wall parts which each form a periphery segment of an inner periphery of the precipitation tube and are connected to each other so as to form at least part of the inner circumference of the precipitation tube. The modular tube system may include at least two wall parts, which each form a length segment of the precipitation tube and are connected to each other so as to form at least part of the length of the precipitation tube. The precipitation tube bundle is modular and includes a supporting structure on which a plurality of precipitation tubes are detachably held by connecting elements.
