Abstract:
A control device is configured to estimate a soot deposition amount (PM deposition amount) in a DPF for an exhaust purification device that is configured to purify exhaust of a diesel engine using the DPF, and determine a regeneration timing for the diesel engine based on the estimated PM deposition amount. As a technique of determining the regeneration timing, the control device employs a first determination technique of detecting that the PM deposition amount is a first threshold or more and a state in which the PM deposition amount is the first threshold or more has continued for a first predetermined time and a second determination technique of detecting that the PM deposition amount is a second threshold (>the first threshold) or more and a state in which the PM deposition amount is the second threshold or more has continued for a second predetermined time.
Abstract:
An oil separator is provided with a case that has an air inlet and a plurality of expansion chambers formed within the case. Air that contains oil is introduced into the case via the inlet and caused to strike a impingement plate to thereby separate the oil from the introduced air and recover the oil. The transverse cross-sectional area of each expansion chamber is greater than the open area of the inlet. Partition walls with orifice holes formed therein are provided between the expansion chambers.
Abstract:
A water separator for use in a marine exhaust system comprises a horizontally disposed, generally cylindrical housing including a wet exhaust inlet, a dry exhaust outlet, and a water outlet. Wet exhaust entering the wet exhaust inlet is constrained against the inner housing wall by a variable geometry vane or baffle which causes the wet exhaust to accelerate such that centrifugal force causes the entrained water to separate from the exhaust gas. Separated water encounters a longitudinally disposed barrier and flows to the water outlet for discharge from the vessel. A tubular dry exhaust pipe is longitudinally disposed within the housing and includes an inlet disposed in proximity to a first end thereof, and an outlet projecting from a second end thereof.
Abstract:
A mitigating system to remove contaminants from an exhaust gas and generate electrical power utilizes a first and second particle acquisition tower (PAT) unit, a first and second carbon dioxide precipitator (CAP) unit, a clean air turbine (CAT) unit, and a first and second gravity enhance separator (AGES) unit. The first PAT unit receives and purify the exhaust gas as the first AGES unit is in fluid communication with the first PAT unit. The exhaust gas is then respectively discharge and purified through the first CAP unit, the CAT unit, the second PAT unit as the second AGES unit is in fluid communication with the second PAT unit. Then the exhaust gas is discharged and purified through the second CAP unit and released into atmosphere as clean exhaust gas. Additionally, the exhaust gas is able to produce electricity as the exhaust gas bypasses within the CAT unit.

Provided is a particulate filtration apparatus for removing combustible and noncombustible particulate matter from a lean burn engine exhaust gas stream containing particulate matter. The apparatus comprises a cyclone body with a roughened surface on the inner walls designed to trap and agglomerate the combustible particulate matter. A catalyst, selected from a selective catalytic reduction catalyst, an ammonia oxidation catalyst, a hydrolysis catalyst, an oxidation catalyst, a three-way catalyst, and combinations thereof can be coated on the roughened surface. Also provided is a system and methods for treating an exhaust gas stream.
Abstract:
A method for low-contamination generation of energy comprising: (a) forming a gas mixture by mixing a treated gaseous effluent stream and air; (b) introducing the gas mixture and fuel at a given gas to fuel ratio into at least one diesel engine (3); (c) burning the fuel in the diesel engine to generate energy and a flue gas stream comprising particulate matter (PM), and nitrogen oxides (NOx); (d) treating at least a portion of the flue gas stream with an aqueous stream in a cyclone unit (27) comprising a housing defined by a cylindrical peripheral wall (2) and provided with at least one inlet opening (10) for receiving flue gas and at least one inlet opening for receiving fluids thereinto and with at least one swirling means, whereby a treated gaseous effluent stream and an aqueous effluent stream are formed; (e) emitting a portion of the treated gaseous effluent stream to form an emitted portion; (f) using a portion of the treated gaseous effluent stream to form the gas mixture, and (g) repeating steps (a) through (f) multiple times.
Abstract:
A particle matter agglomeration system (100) enables cost effective and efficient filtration of aerosols. The system (100) includes an acoustic chamber (110) for receiving an aerosol, and an ultrasonic transducer head assembly (300) for supporting an ultrasonic transducer (400). A transducer plate (410) faces into the acoustic chamber (110) for applying ultrasonic energy to the aerosol inside the acoustic chamber (110). A shaft (405) extends through the head assembly (300) and connects the transducer plate (410) to the ultrasonic transducer (400). A cooling jacket (315) is positioned around the shaft (405) and between the transducer plate (410) and the ultrasonic transducer (400), wherein the cooling jacket (315) receives cooling fluid for cooling the ultrasonic transducer (400).
Abstract:
An exhaust pipe (100) for a fuel burning engine including a hollow body, the body having an internal surface (120), an external surface (110), a first open end (130), a second open end (140) and a longitudinal axis, wherein the internal surface (120) is shaped to form standing cyclic wave geometry having at least 2 cycles (c). When gas containing inhalable particles (22) enters the exhaust pipe (100) through the first open end (130) and flows out of the exhaust pipe (100) through the second open end (140), a substantial amount of inhalable particles (22) are grouped to form filterable particles (182).
Abstract:
An oil separator includes a casing that has an inlet for air and an outlet for air, and an impingement member that is provided inside the casing. Air that contains oil is introduced through the inlet into the casing and caused to strike the impingement member so that the oil is separated from the introduced air and is recovered. The outlet opens in the horizontal direction of the casing. The oil separator further includes an L-shaped elbow member that is attached to the outlet. The elbow member protrudes in the horizontal direction from the outlet and is bent upward.
Abstract:
A centrifugal separator for separating particles from a fluid has a housing with a structural element provided with an opening. A cyclone cell having an inflow opening and an outflow opening is provided and is adapted to produce a swirl in a fluid that is flowing in through the inflow opening and exits through the outflow opening. The cyclone cell is secured in the opening of the structural element by being form-fittingly embedded by injection molding in the structural element. In a method for producing the centrifugal separator, at least one cyclone cell is provided and is embedded by injection molding so as to form the structural element that secures at least one cyclone cell in the housing.
