Contaminants and solution micro-droplets suspended in the air, settle out by acceleration of gravity into the wet surfaces of each bubble. The froth is dewatered by condensation onto cold refrigerant coils (820). The liquid solution and contaminants drain from the refrigerant coils (820) into the solution reservoir (808). Solution micro-droplets remaining in the air steam are separated by a centrifugal blower/droplets (140) separator and drain back into the solution reservoir (808). The air steam is passed through condensing refrigerant coils (160) to reheat the air steam.

Valve assembly

A valve assembly 200 including a housing 202 with an internally projecting lip 226 that seals against an outer surface of a valve stem 220 inserted through it. A gas inlet 234a is provided above the lip 226 and a liquid inlet 212 is provided below the lip. The lip 226 thus ensures that a gas flow path and a liquid flow path are kept separate until the valve stem 220 is moved to an open position, at which point a liquid inlet hole 284 in the stem is brought into communication with the liquid inlet 212 in the housing and a gas inlet hole 286 in the stem is brought into communication with the gas inlet 234a in the housing for the fluids mix in an outlet conduit 280 in the stem. The arrangement means that there is no contact between the liquid and a sealing gasket 260, thereby avoiding swelling of the gasket that can cause the stem 220 to stick.

Patent DE203004C

Fluid jet gun

A fluid jet gun has a tubular guide (31), a nozzle (27), an inside nozzle (45), and liquid piping (50). The tubular guide (31) extends forward and has a brush (34) embedded in the guide. The nozzle (27) is constructed from a flexible tube material whose front end side is adapted to be a free end. One gas flow, out of the gas flows obtained by branching a gas flow by a branch section (25), is supplied to and passed through the nozzle (27). By this, the nozzle (27) rotates with guidance by the tubular guide (31), jetting the gas flow from its front end toward the brush (34). The inside nozzle (45) jets, from its front end, the other gas supplied from the branch section (25) and having passed through a flow rate regulation section (37). The liquid piping (50) penetrates through the tubular guide (31) to interconnect the inside of the tubular guide (31) and a liquid supply source (12). The inside nozzle (45) is inserted in the liquid piping (50) at its intermediate position so as to be directed to the tubular guide section (31). The liquid piping (50) sucks liquid from the liquid supply source (12) by an effect of negative pressure produced by jetting of the gas from the inside nozzle (45) and jets the liquid to the inside of the tubular guide (31). The fluid jet gun can mix a sufficient amount of the liquid with the gas and jet the mixture in fine particles.
