  • Painting system using desiccant dehumidifier for conditioning and removing VOCS from ventilation air to be returned to spray booth
    Patent number: 6010562
    Abstract: A painting system includes a paint spray booth ventilated by process air including a combination of outside make-up air and a portion of the exiting process air which is returned to the booth, the returned air being the main component of the combination. The humidity of the air in the paint spray booth is controlled by routing a first minor portion of the process air, exiting the booth, through a desiccant dehumidifier, which removes moisture and volatile organic compounds (VOCs) from this process air portion before it is sent back to the paint spray booth. The dehumidifier is designed so that at any given time the process air portion contacts only part of the desiccant bed while air heated to approximately 250.degree. F. in a paint cure oven is exhausted from the oven and directed through the remaining part of the desiccant bed in order to dry, and thus regenerate, the desiccant for continued use.
