A gas conditioner 60 comprises: a case 62 that forms a gas flowpath 61 through which gas flows; and resin members 80 that are provided to the gas flowpath 61 and that are water permeable. The resin members 80 are formed of sealed hollow bodies that are filled with water.

This mixing member is provided with a base portion disposed in the exhaust pipe, separated from an inner wall thereof, and a plurality of blade portions which extend from the base portion toward the inner wall, and which generate a swirling flow of the exhaust gas on a downstream side, in the exhaust direction, of the mixing member, wherein: the blade portions are disposed inclined with respect to the exhaust direction such that the position of a connecting portion with the base portion is at a most downstream position thereof, in the exhaust direction; and the base portion includes a reducing agent passage which penetrates through both end surfaces thereof in the exhaust direction, and which allows the reducing agent to pass through from an upstream side to a downstream side of the mixing member in the exhaust direction.

An air purifying apparatus includes a humidity controller and an intake cooling separator including one or more shafts and an outer wall. The intake cooling separator generates airflow to obtain the humidity-controlled air. The intake cooling separator swirls the obtained air around a first shaft included in the one or more shafts, thereby generating a pressure difference between air included in the obtained air and around the first shaft and air included in the obtained air and around the outer wall, and the pressure difference cools at least a part of the obtained air, and the pressure difference cools at least a part of the obtained air. The intake cooling separator performs centrifugal separation of water droplets generated from the cooled air. The one or more shafts are rotated to generate the airflow, to cause the swirl, and to perform the centrifugal separation.

A gas-liquid contact apparatus has a gas-liquid contact unit, a liquid supply system, and a gas supply system. The gas-liquid contact unit includes a plurality of stages which are allocated so as to be arranged in the lateral direction. Each of the plurality of stages includes a plurality of vertical flat plates arranged parallel to each other at intervals. The liquid supply system supplies a liquid to the gas-liquid contact unit, and causes the liquid to be circulated along the arrangement of the plurality of stages successively. The gas supply system supplies a gas to the gas-liquid contact unit, and causes the gas to be circulated along the arrangement of the plurality of stages successively. The supplied liquid flows down on the plurality of vertical flat plates in each of the plurality of stages, and comes into contact with the supplied gas.

A two-stage mixer may include a guiding element and a mixing element. The guiding element may be configured to be fixedly mounted to an interior of an exhaust conduit. The mixing element may be configured to be fixedly mounted to the interior of the exhaust conduit in a position downstream from the guiding element. The mixing element may include a central disk, a plurality of mounting arms extending radially from the central disk, and a plurality of blades extending radially from the central disk. At least one mounting arm of the plurality of mounting arms may include a fin extending therefrom, and at least one blade of the plurality of blades may include a fin extending therefrom.

A cartridge for a fragrance dispensing device includes a hollow body having an inlet and an outlet, and an accumulator for odorant composition in the hollow body. The cartridge further includes a closer for the inlet and outlet. Also disclosed is a device for dispensing fragrances, having a housing including: at least two receptacles, each removably receiving a cartridge, each receptacle including an air inlet and exhaust, connected respectively to the inlet and outlet of a cartridge and also act on the closer of a cartridge in the receptacle to move them in the open position, a generator of air flow through the receptacles between the inlet and exhaust, and a control unit controlling the air flow generator and the inlet and exhaust and ensures an independent or simultaneous dispensing of the compositions in the cartridges in variable proportions and closure of the cartridges when the apparatus is stopped.

An air scrubber has an electrically driven fan and a drum having a mat forming a closed circulating band spanning a support of the drum. The mat is electrically rotatably driven about a rotation axis, wherein a lower part of the drum is immersed in a water basin. The mat can be removed from the drum by a movement in the axial direction and pushed back on again by a movement in the axial direction.

The embodied invention is a low humidity generator which encapsulates essential piping, pressure regulator, flow regulator, and saturator in a sealed vacuum chamber. Additionally, a Stirling piston type cooler is used to cool the saturator. This eliminates atmospheric water vapor permeation and the need for thermal insulation surrounding the piping and control units. Also, the humidity generator has improved cool down characteristics, improved thermal control, and better maintenance access.

A mixer assembly having a plurality of mixer vanes, each of the plurality of mixer vanes having a first end, a second end, and a body portion extending between the first end and the second end, the body portion having a length, a width, a thickness, a cross-sectional area, a curvature, and a twist, wherein each of the plurality of mixer vanes has a 3-dimensional shape defined by the length, width, thickness, cross-sectional area, curvature, and twist of the body portion, and wherein at least one of the plurality of mixer vanes has a non-uniform 3-dimensional shape.
