the nozzle 22 the air stream then passes through the chamber inlet 52 and into the vaporization chamber 16 much of the liquid deodorant distributed to the vaporization chamber 16 will be vaporized within the vaporization chamber remaining un vaporized particles of liquid deodorant form on the vaporization chamber side wall 64 and fall to the chamber floor 62 the un vaporized liquid deodorant eventually returns to the deodorant reservoir 32 as gravity draws the deodorant to the chamber floor 62 down the incline of the chamber floor 62 through the chamber inlet 52 and into the deodorant reservoir 32 the air stream exiting the vaporization chamber 16 contains treated air comprised of fresh ambient air and vaporized deodorant along with a small portion of tiny suspended particles of liquid deodorant treated air flows up through the vaporization chamber outlet 52 and is routed by air ducts 17 to the pressure blower 18 the treated air is drawn to the fan of the pressure blower 18 passes through the fan of the pressure blower and is then forcibly pushed through the distribution pipes 20 and out the vapor release ports 26 to condition an odor source 5 as shown in fig5 the odor source 5 might be an open tank 70 such as sewage treatment plant tank and the distribution pipes 20 may be deployed along and around the perimeter of the open tank 70 to generate an air curtain of vaporized deodorant around the odor source 5 an alternative embodiment of the invention is shown in fig6 10 in this embodiment of the invention the vaporization chamber is vertical rather than horizontal the vertical vaporization chamber can be particularly useful if the system must be installed.
