Abstract: A system and method recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. A foam media absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.

Abstract: In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the condensable fluid into the bath. Energy from condensation is recovered to a coolant in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.

Abstract: The invention proposes a method of destruction of volatile organic and inorganic compounds in wastewater, this method includes following stages: stripping the aforementioned volatile compounds in a stripping-chemisorption column; preliminary heating the gaseous medium containing these volatile compounds in a first heat regenerator; thermal, flare or thermo-catalytic oxidation of the volatile compounds in circulating gaseous medium; cooling the gaseous medium in a second heat regenerator; chemisorption of acidic gases from the gaseous medium in the stripping-chemisorption column with stripping at the same time additional amount of the volatile compounds from the wastewater. After specific period, direction of the gaseous medium flow is alternated. The proposed method can be executed at elevated temperature. The invention includes as well systems realizing the proposed method.

Abstract: A centrifugal separator device for concurrent separation of solid and/or liquid particles suspended in a gaseous media includes a rotor having a multiplicity of sedimentation members and which is mounted rotatably in a surrounding housing. An intake is provided for the gaseous medium to be cleaned, which leads to a central inlet shaft of the rotor. The housing has an outlet for cleaned gas, which has been freed of solid and/or liquid particles on passage through the sedimentation members in the rotor, and an outlet for the solid and/or liquid particles, which have been deposited on the sedimentation members and then transferred to a side wall of the housing by a centrifugal force. A nozzle is arranged upstream of the sedimentation members in order to supply a liquid to the sedimentation members.

Abstract: Particles may be used to filter oleo material such as grease from a flow of fluid such as a gas. The particles can be arranged into a bed to filter the oleo material from the fluid. The filtrate substance collect on the inorganic particles. The particles are re-usable, in that they can be subjected to filtrate-separation techniques, e.g., solvent extraction, detergent washing, and centrifugal separation, to separate the oleo material from the particles.

Abstract: A washable air filter for an internal combustion engine which has high durability and can be washed with ease to reuse it is disclosed. The washable air filter includes an outer cylindrical member 10; an inner cylindrical member 11; a first filter element 30 formed from a stainless mesh sheet which is folded in a pleated-form having peaks and valleys arranged alternately and provided between the outer cylindrical member 10 and the inner cylindrical member 11; and a second filter element 33 provided between the outer cylindrical member 10 and the first tilter element 30. Since the washable air filter uses the filter element made from the stainless mesh sheet, it is possible to effectively remove dust particles from air. Further, the washable air filter can be reused because dust particles are removed off the filter element by washing after use.

Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

Abstract: A gas turbine suction air filter is provided wherein, despite a large capacity, dust is easily removed by an ultrasonic washer. A gas turbine suction air filter (1) has a box-like frame member (3) and a filter cloth (5) contained in the frame member (3). The frame member (3) is made of a metal material, preferably a stainless steel. The filter cloth (5) is formed having many pleats so that many folded faces (7) are formed. No intervening member is provided between adjacent folded faces (7, 7), with only a space being arranged there. The filter cloth (5) is a non-woven fabric of a synthetic resin fiber, preferably a polypropylene fiber. While this filter (1) has a large capacity, an ultrasonic wave reaches the entire filter cloth (5) when the filter (1) is washed by an ultrasonic washer.

Abstract: A main body of exhaust cleaning system 15 is arranged in a hood 8 that is connected to an exhaust duct 14 at an upper part and is opened at a bottom face. A grease filter 23 is arranged at a side plate of a main body case 18 having an inlet 19 into which an exhaust air 5 flows. A filter 33 formed in an endless belt shape by gathering stainless steel wires and the like is attached to rotary shafts 25a, 25b provided to freely rotate in the main body case 18. The filter 33 adheres to the grease filter 23 and a discharge opening 10 through which the exhaust air 5 flows, and is partially immersed in a cleaning liquid 40 in a cleaning liquid tank 22 provided at a lower part of the main body case 18. The exhaust air 5 flowing from the inlet 19 through the grease filter 23 is flown through the rotationally moving filter 33, is flown again from a space 36 through the filter 33, and is discharged after being cleaned. A cleaning of the exhaust air 5 and a cleaning of the filter 33 can be done at a time.
