A venturi-type composite nozzle device for suctioning and removing air pollutants is disclosed. The venturi-type composite nozzle device suctions air pollutants in the vicinity thereof by using negative pressure formed through the venturi principle, and then mixes same with water, jets the mixed water and brings same into contact with the air pollutants again, so as to have a large adsorption ratio of air pollutants in comparison to the amount of water usage, and enables water to be reduced by that amount, and thus has excellent operating performance. To perform such functions, the device employs a venturi-type intake casing, an introducing-spray nozzle, and an impeller.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes an air cleaner suctioning external air and generating filtered air by filtering suctioned external air; and an air washer separably placed on the air cleaner, supplied with filtered air from the air cleaner, and humidifying filtered air.

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

A sensor-based motion control fugitive dust suppression system comprises: a laser pointer provided on a frame to conduct a setting operation such that directions of a plurality of mist spray injection nozzles provided on a blast pipe located inside the frame correspond to the front end of a chisel of a hydraulic breaker; a data logger for collecting, from a sensor provided at the crushing apparatus, location source information for a hitting impact point of the hitting part; a location information processing unit analyzing the location source information collected from the data logger so as to generate the location information on the hitting impact point of the hitting part; and a system control unit for outputting a control signal so as to control a driving unit rotating the blast pipe in a vertical or horizontal direction, according to the location source information.

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.

The fan scrubber is provided with a casing having a gas draw-in port and a gas ejection port, a fan disposed in the casing, a nozzle from which a liquid is jetted into the casing, and a canned motor connected to the fan. The canned motor has a main shaft connected to the fan, a rotor which rotates integrally with the main shaft, a stator disposed on the periphery of the rotor, a motor casing in which the rotor and the stator are housed, and a can which partitions the interior of the motor casing into a rotor chamber in which the rotor is disposed and a stator chamber in which the stator is disposed.

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.
