Abstract: A particle diameter is decreased and a surface area per unit flow amount is increased by spraying a VOC-containing liquid from a spraying device spraying that is a two-fluid nozzle in a vacuum container, so that only water in the VOC-containing liquid can be greatly evaporated and exhausted, and a concentrated VOC-containing liquid having high concentration can be refined and processed.

Abstract: A projection apparatus includes a plurality of two-fluid nozzles, a projection-apparatus-side-gas-flow-path, a gas valve, a projection-apparatus-side-liquid-flow-path, a liquid valve, a projector, a mist concentration measurer, and a controller. The controller starts and stops spraying of a mist by controlling the gas valve and the liquid valve on the basis of an image or a video projected onto a screen from the projector. The controller receives a signal indicating a mist concentration from the mist concentration measurer, starts and stops spraying of the mist by controlling the gas valve and the liquid valve on the basis of the received signal, and thus controls the mist concentration.

Abstract: A mist spraying unit atomizes a liquid and sprays the liquid as a mist, a light projector irradiates a space into which the mist is sprayed from the mist spraying unit with light, an imaging unit images scattered light by the mist of the light irradiated from the light projector, and an arithmetic unit calculates a mist concentration in the space based on a luminance value of a pixel constituting an image acquired from the imaging unit, thereby stopping spraying of the mist sprayed from the mist spraying unit.

Abstract: A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas introduction portion, a gas-liquid spout portion, a liquid inlet, a gas inlet, a tubular flow passage, a spout, a flow passage having a taper, a straightener, and a projection portion. The liquid inlet allows a liquid flow to enter a gas-liquid mixer which is a space inside the annular gas introduction portion. The gas inlet allows a gas flow to enter the gas-liquid mixer. The straightener has an opening having an uneven shape provided in the flow passage having the taper. The projection portion is provided in the liquid introduction portion, protrudes to the gas-liquid mixer, and forms the straightener and a straightening outlet.

Abstract: A spraying apparatus includes a spraying apparatus main body, a liquid introduction portion, a gas-liquid spout portion, a gas introduction portion, a liquid inlet, a first gas inlet passage, a second gas inlet passage, and a spout. The first gas inlet passage is provided at at least one place of the annular gas introduction portion so as to communicate with the gas flow passage and the gas-liquid mixer, and allows a gas flow flowing through the gas flow passage to enter the gas-liquid mixer. The second gas inlet passage has a gas inlet having a predetermined area ratio, is provided on a downstream side of the first gas inlet passage of the gas introduction portion, and communicates with the gas flow passage and the gas-liquid mixer.

Abstract: In a mist nozzle, a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to the mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow introduces into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side. Therefore, it is possible to promote atomization of the liquid in the gas-liquid mixing section and spray a liquid having a smaller particle diameter.

Abstract: A sanitization mist shower apparatus includes a water tank that stores water, a plasma generator that causes a plasma discharge in water inside the water tank and generates reformed water, an air blower that blows pressurized air, and a mist nozzle that spouts fine mist obtained by mixing the reformed water supplied from the water tank and the pressurized air supplied from the air blower. A liquid pressure of the reformed water supplied to the mist nozzle and air pressure of the pressurized air are substantially the same as each other.
