The at least one fan includes a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, and a motor coupled to the blade assembly. The system includes at least one nozzle in fluid communication with the vapor device and proximate the discharge opening. The at least one nozzle is configured to disperse an odor neutralizing chemical vapor in the same first direction of the airflow from the discharge opening. ## Claims ### Claim 1 An odor control system for landfills comprising: a dry vapor device configured to generate an odor neutralizing dry vapor without use of water or an aqueous carrier; and a plurality of fans configured to be directed at a working face of a landfill, each fan comprising a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, a motor coupled to the blade assembly and configured to drive the blade assembly, and a manifold coupled to a plurality of nozzles in communication with the dry vapor device, the plurality of nozzles being positioned proximate the discharge opening and downstream of the discharge opening, wherein the plurality of nozzles are configured to introduce the odor neutralizing dry vapor into the airflow from the discharge opening in the same first direction; wherein the plurality of fans are adjusted to direct the airflow toward the working face and toward adjacent fans such that the airflow from adjacent fans overlaps to form an odor control barrier comprising a suspended volume of odor neutralizing dry vapor around the working face. ### Claim 2 (depends on 1) The odor control system of claim 1, wherein the odor neutralizing dry vapor comprises at least one chemical from an amino hydroxyl group. ### Claim 3 (depends on 1) The odor control system of claim 1, wherein the fan housing comprises a cylindrical shape. ### Claim 4 (depends on 1) The odor control system of claim 1, wherein the blade assembly comprising a plurality of blades extending outward from a central hub. ### Claim 5 (depends on 1) The odor control system of claim 1, wherein the motor is positioned within the passageway of the fan housing. ### Claim 6 (depends on 1) The odor control system of claim 1, further comprising an air compressor in fluid communication with the plurality of nozzles. ### Claim 7 (depends on 6) The odor control system of claim 6, wherein the odor neutralizing dry vapor comprises an odor neutralizing chemical that is entrained into the airflow. ### Claim 8 (depends on 1) The odor control system of claim 1, further comprising: a plurality of contiguous pipes in fluid communication with the dry vapor device disposed parallel to a ground surface and along a perimeter of a landfill, each of the pipes comprising a plurality of apertures; a plurality of vertical support columns carrying the plurality of pipes above the ground surface; and wherein the odor neutralizing dry vapor is configured to be dispersed through the plurality of apertures. ### Claim 9 An odor control apparatus for landfills comprising: a mobile platform configured to be moved to temporary locations proximate a working face of the landfill; and an odor control system carried by the mobile platform, the odor control system comprising a dry vapor device configured to generate an odor neutralizing dry vapor without use of water or an aqueous carrier, and a plurality of fans, wherein each fan comprises a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, a motor coupled to the blade assembly and configured to drive the blade assembly, and a manifold coupled to a plurality of nozzles in communication with the dry vapor device, the plurality of nozzles being positioned proximate the discharge opening and downstream of the discharge opening, wherein the plurality of nozzles are configured to introduce the odor neutralizing dry vapor into the airflow from the discharge opening in the same first direction; wherein the plurality of fans are adjusted to direct the airflow toward the working face and toward adjacent fans such that the airflow from adjacent fans overlaps to form an odor control barrier comprising a suspended volume of odor neutralizing dry vapor around the working face. ### Claim 10 (depends on 9) The odor control apparatus of claim 9, further comprising an odor neutralizing chemical supply carried by the mobile platform and in communication with the dry vapor device. ### Claim 11 (depends on 10) The odor control apparatus of claim 10, further comprising an air compressor in fluid communication with the plurality of nozzles.
