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.

Spraying apparatus

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.

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.

Projection apparatus

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.

VOC refining apparatus

A spraying apparatus is configured such that a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to a 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 is introduced 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.

Spraying apparatusincludes: inner lid; outer lid; and gas-liquid mixing sectionbetween inner lidand outer lid, wherein a liquid is introduced into gas-liquid mixing sectionfrom a position upstream and proximate outer lid plateof outer lid, and a gas is introduced into gas-liquid mixing sectionfrom an opposite position, the liquid is atomized in gas-liquid mixing sectionby the liquid impinging with the gas and transforming into a gas-liquid mixed fluid, and advancing to spouting portionas the gas-liquid mixed fluid is circulated along outer lid plateof outer lidin gas-liquid mixing section

A spraying apparatus includes: an inner lid; a flow guide plate; and an annular member, wherein a liquid is introduced into a gas -liquid mixing section between the inner lid, the flow guide plate, and the annular member from an inner lid plate of the inner lid, the inner lid plate being a flat plate located upstream of the spraying apparatus and proximate the gas-liquid mixing section, and a gas is introduced into the gas-liquid mixing section from an opposite position, the liquid is atomized in the gas-liquid mixing section by the liquid impinging with the gas and transforming into a gas-liquid mixed fluid, and advancing to a spouting portion as the gas-liquid mixed fluid is circulated in the gas-liquid mixing section along the internal surface of the annular member on the flow guide plate and facing the gas-liquid mixing section.

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.

Sanitization mist shower apparatus

A sorting member with an optimized surface shape is adopted to pressurize a mixture heated on the sorting member to allow a melted resin mixed in the mixture to adhere to the sorting member to sort the resin from an unmelted resin. Thus, resin materials are sorted and recovered from unwanted home electric appliances and the like at a high purity.

Method of sorting resin

A separation object including at least two types of resins with different glass transition temperatures (glass transition temperature of a first resin&#x3c;glass transition temperature of a second resin) is placed on a separating member. Next, primary heating is applied at a temperature between the glass transition temperatures of the first resinand the second resin, and pressurization is additionally performed to cause the first resinto adhere to the separating member. Subsequently, a heat history of secondary heating at a temperature higher than the primary heating temperature is applied to detach and recover the second resinby restoring the shape of the second resin, while the first resinadhering to and retained by the separating memberis detached by a bladeand the like for recovery.
