ABSTRACT:
A device that reclaims industrial fluids. Solid contaminants are removed from the liquid being reclaimed by a series of increasingly fine filter elements positioned within a filter housing. The substantially solid contaminant-free fluid then enters an evaporation chamber having a design that constrains the fluid to form a thin film atop an evaporation plate at the bottom of the chamber to facilitate evaporation of volatile contaminants. Insert members are positioned within the evaporation chamber to increase the surface area of the thin film to further enhance the removal of the volatile contaminants. The temperature and pressure of the evaporation chamber is controlled by a heating element that is under the control of a temperature sensor. Evaporated volatile contaminants escape the evaporation chamber through a port formed in the head that closes the device. Latches are used to secure the head in the absence of conventional nuts and bolts, and the head screw threadedly engages the evaporation plate. The device is adapted to hang freely so that it is held level by gravity to insure that the fluid is evenly distributed.
