Abstract:
An arcing electron stream apparatus and method for reducing pollutants in a fluid. The device includes first and second electrodes and a chamber there-between. Voltage is impressed between the electrodes at a frequency, thereby causing a plurality of arcing electron streams to occur between the electrodes. The electrodes have stepped surface such that the central first section of the electrodes are in closer proximity to each other than are the outer second sections. This stepped configuration causes arcing electron streams to progressively be formed along the electrodes and, thus, traverse throughout the chamber, thereby effectively treating molecules within the chamber.
Abstract:
The invention concerns a system for neutralising polluting gases contained in particular in gas oil or gasoline internal engine exhaust gases, or stack effluents. It consists of mutually assembled or integrated modules, selected according to the polluting gas flow rate and their type, among all or part of the following modules: pyrolytic oven module (70) with hollow metal or mineral balls, comprising protuberances forming a very large exchange surface with the polluting gases, or with stacking of pyrolytic plates or electric resistors; module (71) for filtering particles and HC and for purifying polluting gases; module (72) for injecting a deodorant and neutralising liquid such as Zinc RINICEOLAT injected with compressed air ensuring its vaporisation; module (73) for abating noise and reducing gas temperature. For high or very high flow rates of polluting gases, the pyrolytic function is provided by an battery of pyrolitic ovens comprising an input manifold and an output manifold co-operating, when necessary, with a fume extractor.
Abstract:
A combustor (10) for enhancing the combustion of entrained fuel or oil in the exhaust stream of an internal combustion engine is provided. The combustor (10) includes a housing (20) and an expansion chamber (60) inserted into the exhaust stream. The housing (20) forms a cylindrical combustion chamber (27) which is transected by an ignition module (30) with a combustion grill (31). The ignition module (30) includes an insulator ring (40) in which two grates (32, 34) of electrodes (50) are mounted to form the combustion grill (31). The electrodes (50) are elongate rods which extend across the open area of the insulator ring (40) to form multiple chords of varying lengths. The electrodes (50) in each grate (32, 34) are oriented such that their central axes are parallel and substantially coplanar to adjacent electrodes (50) within the same grate (32, 34). The grates (32, 34) are substantially parallel, but rotated such that the central axes of the electrodes (50) of one grate (32, 34) are perpendicular to the central axes of the electrodes of the opposing grate (32, 34) to create a lattice-type electrode (50) configuration. A cascading electrical arcing pattern and distribution among the nodes formed between various electrodes (50) is provided. The arcing between electrodes (50) of the combustion grill (31) is controlled and managed by a spark generation module (70) which includes a computer module (76) which is programmable to appropriately modify arcing variables such as voltage and switching frequency based upon feedback from sensors in the exhaust stream.
Abstract:
A decomposition chamber for an aftertreatment system includes a body and a diffuser. The body includes an inlet, an outlet, a thermal management chamber, and a main flow chamber. The inlet is configured to receive exhaust gas. The outlet is configured to expel the exhaust gas. The thermal management chamber is in fluid communication with the inlet. The thermal management chamber is configured to receive an exhaust gas first portion from the inlet. The main flow chamber is in fluid communication with the inlet. The main flow chamber is configured to receive an exhaust gas second portion from the inlet and to receive the exhaust gas first portion from the thermal management chamber. The diffuser is positioned within the main flow chamber. The diffuser includes a diffuser inlet portion and a diffuser flange portion. The diffuser inlet portion includes a plurality of diffuser perforations.
