A duct cleaning apparatus for cleaning an inside surface of a duct including an elongated flexible element extending inside the duct having a first end supported in the duct spaced from an inside surface, a second opposed free end and having a length sufficient to engage the inside surface of the duct, preferably greater than the diameter of the duct. Fluid flow through the duct, particularly turbulent flow, causes the elongated flexible element to oscillate or flap, striking the inside surface and removing foreign material from a predetermined portion of the inside surface of the duct. The apparatus of this invention may be used to create a fire break, for example, by removing flammable particles or dust from an area of the duct, preventing a flame from propagating along the duct through the flammable material.

A baffle system for separating entrained liquid from a gas stream including columns of U-shaped baffles extending into a liquid trough and including flashing at the top of the baffles on opposed sides, wherein the wet side flashing is longer than the dry side flashing, and a trough baffle directing the air stream upwardly reducing re-entrainment of liquid. The flange portions of the columns of baffles are spaced to provide for cleaning.

A spray application system includes an enclosed spraybooth area in which airborne particles are generated and a scrubber system is located below the enclosed spraybooth area. The scrubber system includes an inlet receiving water and air from the spraybooth area along with airborne particles. The scrubber system transfers the airborne particles to the water for cleaning the air. A generally downwardly opening noise reflector is located directly over the inlet of the scrubber system and is configured to reflect sound generated by the scrubber system back into the inlet of the scrubber system. The reflector is spaced from the inlet of the scrubber system a distance equal to approximately the width of the inlet.

A scrubber assembly for removing particulate paint from a flow of air through a paint application booth is disclosed. A sheet of water received from a water source flows over flood pan collecting paint particles suspended in the flow of air. A separation chamber receives air and particulate paint from the booth and water from the flood pan through first and second scrubbers. The first and second scrubbers extend downwardly from the flood pan. Each scrubber includes an inlet receiving air and particulate paint from the paint application booth and water from said flood pan. The first scrubber includes a first outlet discharging a first stream of air, particulate paint, and water received from the first inlet. The second scrubber includes a second outlet discharging a second stream of air, particulate paint and water received from the second inlet. The first and second streams intersect within the separation chamber.

An oven for heating a coating on a substrate, such as a painted vehicle body, including a first zone having radiant tubes and shields above the tubes and a second zone including side heat chambers having nozzles directing heated air onto a coated substrate and a hold zone. The radiant tubes may include a first linear portion extending through the oven and return loop beneath the substrate to conserve energy and sill ducts directing heated air against the underside of the vehicle body. The temperature is controlled by sensors contacting the radiant tubes and a proportional integral control system.

A pump for transferring particulate material from a source to a remote location, including a particulate chamber having open ends, check valves at the open ends, a vacuum source connected to the chamber adjacent one end, a gas source at the opposed end of the chamber and a control which alternatively connects the vacuum to the chamber to draw particulate material from the source to the chamber and connecting the gas under pressure to drive the particulate material to the remote location. In a preferred embodiment, the chamber has a cylindrical inner diameter and the source of vacuum is a venturi pump connected to a pinch valve permitting overflow of particulate material through the pinch valve and venturi pump, which is returned to the source. In one embodiment, the pinch valve surrounds an open end of the chamber permitting overflow while avoiding agglomeration of the particulate material.

An oven assembly for baking coatings applied to an object includes a housing with a header receiving pressurized air from a ventilator disposed outside the oven. A heater provides heat to the pressurized air received from the ventilator raising the temperature of the pressurized air to between about two and four times curing temperature in Fahrenheit degrees of the coatings applied to the object. The header extends from the heater into the housing. The header has nozzles disposed at spaced locations directing pressurized air at the temperature being between about two and four times the curing temperature in Fahrenheit degrees of the coating applied to the object toward predetermined locations on the object.

A method of designing or evaluating the design of a bake oven for curing paint on an article to achieve the cure criteria for predetermined areas of the article, including creating a three-dimensional model of the article and the bake oven, dividing the three-dimensional model into discreet elements, using a computer to set each discreet element to initial conditions and at an initial time, repeating this step to achieve substantial convergence, comparing the cure criteria with the calculated temperature as a function of time and finally modifying the computational model of the bake oven to achieve the cure criteria based upon a computer simulation.
