An integrated system for onboard scrubbing of a marine exhaust gas on a ship, comprising: a) a Venturi quencher having: i) two liquid inlets that feed quench water to the Venturi quencher; and ii) a hot exhaust gas entry that feeds the hot marine exhaust gas from an engine on the ship; and b) the rotating packed bed device, having: iii) a stationary gas distributor, placed along an outer circumference of the RPB device, that disengages a quenched marine exhaust gas from a cooled two-phase mixture, and uniformly distributes the quenched marine exhaust gas along the outer circumference of the RPB device; and iv) a stationary liquid distributor, centrally positioned, and with multiple liquid rings that are fitted with spray nozzles that spray a seawater along an inner circumference of the RPB device. Also, processes for using the integrated system, and a ship comprising the integrated system.

A device for producing droplets is disclosed. A disk assembly comprising a first disk mounted to a second disk is provided. The first disk comprises first openings. The second disk comprises second openings. The first openings and the second openings alternately align with one another such that, as a liquid passes through the first openings and the second openings, the liquid falls as a droplet as the first openings and the second openings skew apart.

A purification structure is located beside an inlet segment of a heat dissipator and contains: a casing, a water mesh, a water distribution seat, and a water collection device. The casing includes an air inlet and an air outlet. The water mesh includes multiple orifices and is accommodated between the air inlet and the air outlet of the casing. The water distribution seat is secured on a top of the water mesh and includes an aperture and multiple passages. The water collection device communicates with a bottom of the water mesh, and the water collection device includes a water accommodation chamber and a pump, wherein the pump has a water output segment connecting with a guide tube which communicates with the aperture of the water distribution seat, such that the water is outputted by the pump to flow toward the aperture via the guide tube.

An air washer includes an outer case having an air suction port, a water tub disposed in the outer case to store water, a humidification unit disposed in the water tub, a display unit disposed so as to be spaced apart from the outer case to form an air discharge port, the display unit having a water supply port, through which water is supplied, an inner case located at an upper side of the water tub, the inner case having an air channel, connecting the air suction port with the air discharge port, and a water channel, along which the water injected through the water supply port is guided to the water tub, and a blower disposed in the inner case to blow air suctioned through the air suction port to the air discharge port.

Disclosed is a wet air purifier that eliminates contaminants while contaminated air passes therethrough by causing the contaminated air to come into contact with water. The wet air purifier suctions external air by rotating a rotary fan installed therein and disperses water droplets by causing water to collide with a rotary fan to increase a contact surface between air and water. In the wet air purifier, a mixture of the contaminated external air and the water is made to pass through a long narrow passage and guided to a storage tank in which contaminants are settled. In this way, the wet air purifier increases a retention time and a collision time of water and contaminated air. The wet air purifier also can function as a humidifier.

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. The gas scrubber with a rotary atomizer is arranged vertically and centrally in the housing downstream from a wet scrubber. The housing may be a pipe or tube of a same or substantially a same diameter in both the wet scrubber section and the gas scrubber section. An outlet nozzle sprays a cleaning or scrubbing liquid onto a cup-shaped rotor with a tear-off edge of the rotary atomizer to create a turbulent mixture of waste gas particles and liquid. Liquid droplets with entrained particles are propelled from the rotor onto the outer wall of the housing and/or are captured by a droplet separator. The rotor is turned by a spindle motor aligned centrally in the housing.

A fluid gasification, pumping and mixing equipment, for fluids contained in open or closed bodies, which allows to control the bubble size and the proportion of mixed gases, of a gas flow to be diffused into the fluid, which functions to generate a gas suction flow that allows active filling of cavitation zones created by the radial movement of a cavitation propeller, which can be used to suction at different depths without losing suction force or generate higher energy consumption.
