Abstract
The air purification system and method for purifying and cooling air for use in a building has an air pollutant removal stage, an air pre-cooling unit, and a dual cooling and water removal unit, including a cyclone separator having a cooling coil wrapped around the separator for condensing and removing water from the airflow. The method comprises the steps of removing pollutants from an incoming polluted airflow to provide a substantially pollutant free outgoing moist airflow; pre-cooling the substantially pollutant free moist airflow to provide a clean cool moist airflow; and condensing water out of the clean cool moist airflow to provide a substantially clean dry airflow suitable for use in a building.
Claims12
An air purification system for cleaning and cooling air, comprising:
- an air pollutant removal unit having an air inlet and an air outlet;
- a cyclone separator having:
- a housing defining an exterior surface and an interior surface;
- a cyclone air inlet opening into the housing, the cyclone air inlet being connected to the air pollutant removal unit air outlet;
- a cyclone air outlet;
- a heating coil disposed at the cyclone air outlet for regulating air temperature;
- and
- a condensed water discharge outlet;
- and
- a cyclone separator cooling coil disposed around the cyclone separator housing;
- whereby air passing through the air removal unit has any moisture therein condensed and removed in the cyclone separator, together with any remaining air pollutants.
An air purification system for cleaning and cooling air, comprising:
- an air pollutant removal unit having an air inlet and an air outlet, wherein said air pollutant removal unit further comprises a housing defining a chamber having a water recirculation system disposed therein the recirculation system including:
- a water reservoir disposed at a bottom of the chamber for collecting water;
- a water delivery conduit extending into the chamber and having a valve disposed therein adapted for adding water to the reservoir when water in the reservoir drops below a set level;
- a water drain conduit extending from the reservoir and having a water bleed valve therein adapted for draining and sampling the water in the reservoir;
- a plurality of spray heads in the chamber above the reservoir and the air inlet;
- and
- a water pump and conduit connecting the water pump to the reservoir and the spray heads;
- wherein the water pump circulates water from the reservoir to the spray heads in order to produce a water spray for scrubbing pollutants from the air entering the air inlet;
- a cyclone separator having:
- a housing defining an exterior surface and an interior surface;
- a cyclone air inlet opening into the housing, the cyclone air inlet being connected to the air pollutant removal unit air outlet;
- a cyclone air outlet;
- and
- a condensed water discharge outlet;
- and
- a cyclone separator cooling coil disposed around the cyclone separator housing;
- whereby air passing through the air removal unit has any moisture therein condensed and removed in the cyclone separator, together with any remaining air pollutants.

- a cyclone air inlet opening into the housing, the cyclone air inlet being connected to the air pollutant removal unit air outlet;
- a cyclone air outlet;
- and
- a condensed water discharge outlet;
- a pre-cooler unit disposed between the air pollutant removal unit air outlet and the cyclone air inlet, the pre-cooler unit having a housing and a pre-cooler coil disposed in the housing;
- and
- a cyclone separator cooling coil disposed around the cyclone separator housing, the cooling coil being in series with the pre-cooler coil.
