        Dyna-Jet is an improved version of jet-Venturi type scrubbers capable of achieving more efficient gas scrubbing for a given energy consumption.  Gas scrubbing is accomplished by directing high pressure jet sprays into a Venturi to create a zone of high turbulence and intimate gas-liquid contact as the jet sprays thrust through the Venturi, aspirating and entraining the gases along with. The speeding sprays impact and caputure the dust particles as the gas converging into the Venturi throat, while large interphase surfaces resulting from intimate inter-mixing of the gas and liquid facilitate rapid transfer of heat and mass. Cooling of the gas and absorption of soluble and/or obnoxious gases are thus also made possible.  The jet sprays also serve to pump the gas through the scrubber. Up to 2" available draft can be designed to overcome additional ducting loss.

    The scrubbing efficiency of a Dyna-Jet varies depending on the nozzle pressure and liquid to gas ratio used.  Typically, a single stage unit can remove 90-98% of most soluble gases and 98-99% of particles over 2 microns. For removal of obnoxious gases, a suitable neutralizing solution is used for scrubbing.
