A fine-particle sampling device for sampling fine particles in a liquid includes a tubular first electrode whose both ends in an axial direction thereof are open; a second electrode extending in the axial direction of the first electrode and disposed in the inside of the first electrode to be spaced from an inner surface of the first electrode; a supplier that supplies a liquid to the inside of the first electrode and causes the liquid to be stored at a portion of the inner surface in a direction around an axis B of the first electrode; a voltage applicator that applies a voltage between the first electrode and the second electrode; a driver that rotates the first electrode around a rotational axis extending in the axial direction of the first electrode and passing through the inside of the first electrode; and a retriever that retrieves the stored liquid.

A particulate collector includes a housing having an air intake port and an exhaust port and a flow channel, in the housing, connecting the two ports, a fan rotatable about an R-axis to generate airflow in the flow channel, a spray unit that sprays first liquid into a first portion in the flow channel, a first filter located between the first portion and the exhaust port and supported rotatably about the R-axis, a power source that rotates the first filter, a first collection port for collecting a first particulate covered with liquid contained in the first liquid from the flow channel through a second portion in the first filter, and a second collection port for collecting a second particulate covered with liquid contained in the first liquid from the flow channel through a third portion in the first filter. The second portion is located between the first and third portions.

Particulate collection device

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.
