摘要： Disclosed is an apparatus for capturing bioaerosols. More particularly, the apparatus for capturing bioaerosols includes a sprayer configured to spray a buffer solution for protecting aerosol particles in a form of droplets; and a capturer into which air including the droplets and the aerosol particles is introduced and in a capture solution in which the aerosol particles are captured, wherein discharge members provided with a plurality of nanostructures are provided on a surface of the capturer to charge the aerosol particles. Due to such a configuration, high discharge efficiency can be anticipated even at a low voltage without damage to aerosol particles.

摘要： An air scenting system for a vehicle is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance is particularly adapted for dispensing scent into the interior space of a vehicle, and includes a form factor particularly well suited for positioning the appliance in a cup holder. Additionally, the appliance is designed for use in vehicles when a driver is present and readily adjustable by the driver to provide a uniform scent experience.

摘要： A method of producing a cooled dry gas is provided. The method includes exposing an input gas to an aqueous saline solution having a temperature of 20 to 80° C. to produce a first intermediate gas. In addition, the method further includes exposing the first intermediate gas to freshwater having a temperature of greater than −5° C. to less than 20° C. to produce a second intermediate gas. The method also includes cooling the second intermediate gas to a temperature of −40 to −5° C. to produce a cooled gas. The method further includes exposing the cooled gas to a chemical adsorbent to produce a saturated adsorbent and the cooled dry gas.

摘要： There is provided an exhaust gas processing apparatus configured to cause a processing gas to be exposed to or come into contact with a liquid and thereby detoxify the processing gas. The exhaust gas processing apparatus comprises a suction casing provided with an inlet which the processing gas is sucked into and with an outlet which the processing gas is flowed out from; a liquid tank configured to receive an outlet-side part of the suction casing and store the liquid therein; and one or multiple spray nozzles placed in the liquid tank. The outlet of the suction casing is arranged to be located above a liquid surface of the liquid stored in the liquid tank. The one or multiple spray nozzles are configured to spray the liquid from around the outlet of the suction casing to a peripheral part of the outlet.

摘要： A filter system includes a liquid filter unit, a HEPA filter unit and an air vent cover. The filter system is installed into an in-room air vent and purifies air received from a forced air system prior to its entrance into a room via the in-room air vent. In some embodiments, the filter system further includes a means for controlling a temperature of the air such that users are able to independently control air temperature in each room of a building.

摘要： 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.

摘要： The disclosure provides an automatic smokeless oven with far infrared heating including a seat body, a rotating device, an air treatment device and a cooling device. The infrared heater is positioned above a first cavity and used for heating the first cavity so as to prevent grease, sauce and the like from contacting a heating source to generate oily smoke. The rotating device is arranged in a second cavity and used for driving the food to be baked to turn over, so as to realize an automatically turning over of the food. The air treatment device is arranged at the bottom of the first cavity and used for filtering the air in the first cavity to further reduce smoke emission. The cooling device is arranged at the bottom of the first cavity and communicated with the third cavity for driving the cooling water to flow through the third cavity.
