A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.

An apparatus for treating the atmosphere of a storage space for vegetable products with a volume greater than 200 m.sup.3, includes a contacting device having a packing; an injector configured to inject a liquid flow into the contacting device; and a circulator configured to circulate the storage atmosphere in the contacting device. The contacting device is configured such that the storage atmosphere is brought into contact with the liquid flow by circulation in the packing.

The present invention is a portable personalized air purifier intended to be attached to the belt or to the neck of a user. Purified air is generated by filtering, electrochemically, and UV LED treating of a polluted air. Polluted air is forced through a filter into ionized water, which absorbs particles and kills possible air born bacteria. The UV LED disinfects the polluted air. The device further balances the humidity of the air and delivers healthy air towards the face of the user through a mask.

An air purifier comprising: a housing provided with air inlets and air outlets and defining an accommodating cavity, wherein the air inlets are located on the side walls of the housing; a water supply module arranged within the accommodating cavity and defining a water storage cavity; a purifying module arranged within the accommodating cavity and located on the water supply module, the purifying module comprising: a purifying assembly rotatably disposed within the accommodating cavity, a water distribution assembly for guiding water in the water supply module to flow upwards and distributing water to the purifying assembly, and a driving device located on the purifying assembly and connected with the purifying assembly; and an air discharge module disposed within the accommodating cavity and located on the purifying module.

An air sterilizing device, comprising: a housing (100), forming an air flow path thereon; an ozone generating unit (200), generating ozone particles to be supplied to the air flow path; a filter cartridge (300), receiving ozone generated by the ozone generating unit (200) to discharge bubbles comprising ozone and hydroxyl radicals; an ultrasonic generating unit (400), connected to the filter cartridge (300) to generate ultrasonic waves; an air supply fan (500), configured to supply air to the air flow path of the housing (100); and a power supply unit, configured to supply power for driving the ozone generating unit (200), the ultrasonic generating unit (400), and the air supply fan (500).

An odorant masking system is provided that may be used to introduce an odorant masking agent to natural gas released via a vent stack system. When the odorant masking system senses a pressure increase due to a controlled natural gas release (e.g., during a system blowdown), some of the natural gas is diverted through the system, and odorant masking agent is released from a storage tank. The diverted natural gas and the odorant masking agent subsequently may be mixed and introduced to the natural gas being released through the vent stack system. The mixture of diverted gas and odorant masking agent preferably takes the form of a spray that, when introduced to the natural gas at the vent stack, reduces or even neutralizes the foul smell of odorant associated with the controlled release of natural gas.

A method that can efficiently dissolve a water-soluble component contained in a gas with smaller energy consumption is provided. A mist is produced from a liquid. The mist and carrier air is mixed to produce mist-containing air. A solution gas and the mist-containing air are supplied to a static mixer. The solution gas and the mist-containing are mixed by using the static mixer. The liquid mist is brought in contact with the solution gas to dissolve a water-soluble component that is contained in the solution gas into the liquid mist. The liquid mist that contains the water-soluble component dissolved aggregates and produces a solution that contains the water-soluble component dissolved.

A particle collection vessel (2) which charges particles in air and then collects them includes a vessel body (7) having an opening (8); a suction part (14) provided in the opening (8) and having an inflow path (22) through which the air is flowed from an outside into an inside of the vessel body (7); a discharge part (16) provided in the opening (8) and having an outflow path (26) through which the air is discharged from the inside to the outside of the vessel body (7); a discharge electrode (15) provided in the inside of the vessel body (7) and to which a high voltage is applied; and a medium storage part (50) provided in the inside of the vessel body (7) and capable of storing a medium for collecting the particles in the air charged by the discharge electrode (15).

A fluid treatment device including: a pipe having an inlet through which fluid is introduced into the pipe from a fluid treatment space, an outlet through which sterilized fluid is discharged to the fluid treatment space, and a flow channel connecting the inlet to the outlet, the pipe providing a sterilization area in the flow channel; a solvent filling at least a portion of the sterilization area; and at least one light source module disposed in the sterilization area, and including a light source to emit sterilizing light and a substrate on which the light source is mounted, in which the fluid introduced through the inlet passes through the solvent towards the outlet, the solvent traps contaminants contained in the fluid when the fluid passes through the solvent, and the light source module sterilizes the solvent with the contaminants trapped therein.

A device for generating an upwardly blowing air curtain to protect against airborne pathogens and pollutants.
