Abstract:
A device for cleaning surfaces and enclosed systems comprising:a housing having therein a single chamber, the chamber having an outlet and at least two inlets, air introduced, under pressure, into one of the at least two inlets, a cleaning agent introduced, under pressure, into another of the at least two inlets, means to control the rate of flow of air and cleaning agent in each of the at least two inlets, wherein controlled flow rates of cleaning agent and air are introduced into the chamber under pressure forming a mixture of air and cleaning agent therein, a single screen plate disposed in the outlet of the chamber, the screen plate having a plurality of spaced-apart openings therein to produce turbulence in the mixture of air and cleaning agent as the mixture of air and cleaning agent exits the outlet through the screen plate, wherein each of the openings in the screen plate is formed at an angle of 25Â°Â±20Â° with respect to an axial center line through the screen plate, wherein a turbulent mixture of air and cleaning agent exits the outlet of the housing, the turbulent mixture being introduced into a system to be cleaned of substances removable by the cleaning agent, the turbulent movement increasing the cleaning efficiency and reducing the amount of cleaning agent required.
