A device for producing and treating a gas stream is provided that includes an enclosure, of which the lower part is submerged in a liquid supply open at the top and includes at least one liquid intake opening. The submerged lower part of the enclosure contains a volume of this liquid and at least one opening for discharging a gas stream, positioned above the surface of the volume of liquid contained in the enclosure. The device further provides for injecting a gas stream including at least one injection conduit and extends in the upper part inside the enclosure outside the volume of liquid. During operation of the device an incoming gas stream is introduced to create an outgoing gas stream, treated by direct contact with said volume of liquid that is discharged outside the enclosure. A facility inclusive of the device and method of operation are also provided.

The present disclosure relates to a tower type air purifier installed and operated outdoors to purify air pollutants such as fine dust. More particularly, the tower type air purifier is manufactured by modularizing and combining main constituent components of a main body in a tower form in order to easily separate and purify air pollutants in the air. A controller, which prepares an air purification algorithm based on air pollution measurement information, controls a blower, a mist sprayer, an ion emitter, a cleaning water injector and an adsorption brush installed in the purifier to quickly purify a large amount of suctioned air. The purifier can be operated independently or a group of purifiers can be operated through remote control according to an air purification algorithm suitable for each air pollution region and provided from a weather center.

A humidification and air cleaning apparatus is provided that may include a lower base, a lower housing, a plurality of legs, a leg wall, and an input assembly. The lower base may be supported by an installation surface. The lower housing may be spaced apart upwardly from the lower base and form a suction gap by being spaced apart from the lower base. The plurality of legs may be disposed on at least one of the lower base or a lower housing. The plurality of legs may support the lower housing. The leg wall may connect two adjacent legs to each other. The input assembly may be disposed at the lower housing. The input assembly may protrude toward the suction gap. The input assembly may receive a wireless signal. The plurality of legs may include a first leg and a second leg adjacent to each other. The input assembly may be disposed outside of the leg wall. As an input assembly receiving a voice signal is exposed to the outside, a user's voice may be effectively recognized. Further, as the leg wall is disposed between the input assembly and the lower housing inlet, it is possible to suppress propagation of operating noise generated by a blowing unit to the input assembly.

An airborne particle removal system includes a wire filter having a housing that includes a wall. The wall has an interior surface and an exterior surface. The wire filter also has a plurality of layers of wires mounted to the interior surface of the wall of the housing. Each layer in the plurality of layers includes a plurality of wires designed to collect airborne particles from air and release the airborne particles. The system also includes a receptacle configured to receive the airborne particles released from the plurality of wires.

The system also includes a receptacle configured to receive the airborne particles released from the plurality of wires.

The filter according to the present invention is based on the combined action of two materials: tungsten trioxide (WO3), used for implementing the photocatalytic reactor, and a solution of copper (Cu) nanocluster. In a preferred embodiment of the present invention, these materials are applied to suitable supports (filters), one of a mesh/grid made of metal (or other material, e.g. plastics material) for the photocatalyst and the other of fabric made of cotton (or other hydrophilic material), for sanitizing the fluids by way of the use of said supports in systems for air treatment (devices which take the air from the environment and/or from the exterior, filter it, and reemit it after passage through the filtration system in question) and/or water filtration.

The present invention has high efficiency and is a significant innovation, including on the basis of the efficacy tests performed in the present period of health emergency, including on the infective virus COVID-19.

The disclosure relates to a wave vortex air purifier. The wave vortex air purifier according to an embodiment includes an air inhaler configured to inhale air from an outside; a liquid storage configured to accommodate liquid for collecting contaminants contained in intake air inhaled through the air inhaler; a liquid fluidizer placed inside the liquid storage and configured to rotate inside the liquid storage to rotate the liquid in the liquid storage and cause an upwelling phenomenon that a level of the liquid changes; a rotary driver configured to rotate the liquid fluidizer; and an air discharger configured to discharge purified air, from which the contaminants are removed, to the outside.

A multifunctional storage system includes a storage chamber and a machinery chamber provided on a side of the storage chamber. The system further includes a dehumidification part dehumidifying circulating air flowing in the storage chamber; a circulating air inlet and a circulating air outlet enabling the storage chamber and the machinery chamber to communicate; and a circulation filter unit supplying moisture to circulating air supplied to the storage chamber via the circulating air inlet.
