A gas inlet system for a wet gas scrubber includes a weir configured to deliver liquid to a scrubbing passage to wet the interior surface of the scrubbing vessel during operation of the gas inlet system. The weir include a weir duct and a weir trough extending at least partially around the weir duct to receive and at least partially fill with liquid during operation of the gas inlet system. The weir trough has an upper trough outlet in liquid communication with the upper weir duct inlet to deliver liquid from the weir trough into the upper weir duct inlet during operation of the gas inlet system. The weir trough also has a lower trough outlet below the upper trough outlet. The lower trough outlet is in liquid communication with the scrubbing passage to deliver liquid from the weir trough toward the scrubbing passage during operation of the gas inlet system.

An aerosol capture device according to the present invention may include a housing including an air inlet through which air introduced, and an air discharge part through which the introduced air flows and the flowing air is discharged, a capture liquid that is accommodated in the housing and captures an aerosol in the air flowing inside the housing, and a concentration part that is disposed inside the housing, is in contact with the capture liquid, and concentrates the aerosol captured in the capture liquid.

Provided is a dust collection method using a dust collection device. The dust collection device includes: a main body provided in a tubular shape; an exhaust tube provided so as to extend outside from midstream inside the main body through one end of the main body, the exhaust tube cooperating with a suction device to suck air inside the main body; a supply nozzle for supplying a liquid to inside of the main body; a recovery unit for recovering the liquid from the main body; and a pump for returning the liquid from the recovery unit to the supply nozzle. The dust collection method includes: a step of forming a rotating airflow by means of suction with the suction device, the rotating airflow progressing while spiraling along an inner wall surface of the main body; a step of supplying the liquid from the supply nozzle; a step of spreading out the liquid with the rotating airflow on the inner wall surface thereby to continuously form a liquid catcher, the liquid catcher rotating as a film of the liquid; and a step of separating smoke and/or dust to outside by centrifugal force due to the rotating airflow and capturing the smoke and/or dust with the liquid catcher, the smoke and/or dust being contained in air introduced to the inside of the main body.

A complex malodor removing equipment includes: a neutralizing module which dissolves a portion of malodor-causing substances, in malodorous gas introduced from malodor-producing equipment, in liquid water and removes same, which includes an acidity neutralizing module that introduces an alkaline substance from outside and removes an acidic malodor-causing substance from the malodor-causing substances, and an alkaline neutralizing module that introduces an acidic substance from outside and removes an alkaline malodor-causing substance from the malodor-causing substances, and which connects the acidity neutralizing module and the alkaline neutralizing module; and a balancing module which dissolves the remainder of the malodor-causing substances, in the malodorous gas introduced from the neutralizing module, in water and removes same, which includes an oxidation balancing module that introduces an oxidizing agent from outside and balances the malodor-causing substances, and a reduction balancing module that introduces a reducing agent from outside and balances the malodor-causing substances.

A gas scrubber and a waste gas treatment system with a gas scrubber for removing particles from a waste gas has a housing with a waste gas inlet and a waste gas outlet. A substantially circular plate member defining an axis of rotation is rotatably arranged in the housing. Waste gas fed into the housing via the waste gas inlet is directed toward approximately the center of the circular plate member. An outlet nozzle sprays a liquid, especially a cleaning liquid or a scrubbing liquid, onto the circular plate member, in order to obtain a mixture of waste gas and liquid in front of the plate member. A combination of inner and outer rotor arrays, and inner and outer stator arrays are arranged alternatingly and concentrically relative to each other, and separated from the circular plate member, and rotate about the axis of rotation. A rotary atomizer for atomizing the mixture of waste gas and liquid may be arranged on the circular plate member. Particles from the waste gas stream are transferred into the liquid.

A wet scrubber apparatus has a housing with access doors and guides that allow for the installation of self-contained baffle modules. Selected baffle modules can to be inserted, exchanged, removed or left blank (no baffles) within the wet scrubber housing, depending on the desired process. The wet scrubber allows for variable performance and feature-enhancing for a target efficiency and effectiveness. The wet scrubber can incorporate a pump and pipe manifold fluidizer design that can spray water or fluid up onto the modules during operation of the wet scrubber to keep collected material off the baffles. Water can be sprayed throughout the modules onto the baffles during operation, or when the scrubber is offline, isolated from the gas to be scrubbed, during a cleaning operation. This water or fluid can come from an outside source or can be piped and valved to recirculate existing scrub water or fluid.

An apparatus adapted to separate solids suspended in a fluid medium, includes a cylindrical container adapted to contain the fluid medium, an air movement fan operatively connected to the container, the fan being positioned to direct a flow or flows of air onto the surface of the fluid medium at a tangent to the axis of the container, thereby to generate a swirling movement of the fluid around the axis, whereby the solids congregate around the axis from the fluid medium.

Wet-scrubber for cleaning flue gas, said wet scrubber comprising. The wet scrubber comprises a first end and a second end. Furthermore, it comprises an annular wall extending between the first end and the second end so as to form a chamber having a longitudinal axis, said annular wall and said ends having an inner surface and an outer surface, where said chamber comprises an inlet opening and an outlet opening, said openings being in fluid communication and defining a downstream direction from the inlet opening to the outlet opening. Furthermore, the wet-scrubber comprises a liquid distribution system comprising at least one liquid exit aperture for distributing a liquid film on the inner surface of the chamber. Finally, the wet-scrubber further comprises means arranged to rotate the liquid film on the inner surface of the annular wall relative to the annular wall.

According to one embodiment, a dust collection apparatus includes a liquid supplier, a first member, and a liquid recoverer. One end of the first member is connected to the liquid supplier, one other end of the first member is connected to the liquid recoverer. The first member is conductive. The first member has a first surface including a plurality of trenches.
