Device for introducing, injecting or spraying a mixture of a carrier gas and liquid compounds and method for implementing said device

摘要

The invention relates to a device for introducing a carrier gas and liquid compounds or a liquid solution into an evaporation chamber, comprising a mixing chamber, including at least:—a first inlet for the admission of said compounds or said solution,—a second inlet for the admission of the carrier gas,—and an outlet connected to an inlet of an injector, so that a mixture of carrier gas and droplets of said compounds or of said solution is periodically injected, through a single injector outlet, into the evaporation chamber.

主权项

1. A device for injecting or spraying a mixture of carrier gas and at least one liquid compound or at least one liquid solution comprising at least one dissolved liquid, solid or gaseous compound, the device comprising at least one mixing chamber and an evaporation chamber, wherein the mixing chamber is arranged to perform atomization of said compound or said solution in said mixture before said mixture is introduced to the evaporation chamber, the device further comprising at least one inlet for admission of said compounds or said solution and a controller controlling a periodic injection or a periodic spray, by an injector, of said mixture, into said evaporation chamber,
wherein the inlet for admission of said compound or said solution constitutes at least one first inlet of the at least one mixing chamber comprising at least one second inlet for admission of the carrier gas and an outlet connected to an inlet of said injector, so that said periodic injection or periodic spray is performed by injecting or spraying a mixture of carrier gas and droplets of said compound or said solution, through a single outlet of said injector directly into the evaporation chamber, and the volume of the carrier gas in the mixture in the mixing chamber is greater than a volume of said compound or said solution in the mixture in the mixing chamber so as to also atomize in the evaporation chamber said compound or said solution in the mixture by a dispersing blast effect on said compound or said solution when the mixture is passing through the single outlet of the injector along with said compound or said solution, wherein the controller provides a control signal to said injector, the control signal comprising a train of control pulses such that the controller selectively controls an injection frequency and/or a duration of opening the injector according to the train of control pulses, and wherein one or more of the control pulses causes the injector to inject into the evaporation chamber an entire amount of liquid compound or solution introduced into the mixing chamber between two successive openings of the injector.
