  • Patent number: 10800669
    Abstract: A system for removing a gas from a liquid comprises an aeration tank for aerating a raw liquid containing a gas to remove the gas by causing an agitated air flow through the liquid. A plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank, the aeriation plates perforated by a plurality of openings. Aerating the liquid occurs with the liquid flowing downward into the aeration tank, and an airflow flowing upward through the liquid from a point proximate to the bottom of the aeriation tank, wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air.

  • Patent number: 10788000
    Abstract: A system for aspirating a pre-cleaner of a work vehicle may include a fluid conduit in flow communication with an outlet port of the pre-cleaner for receiving an aspirated airflow from the pre-cleaner. The system may also include a double-walled flow pipe having an inner tube that receives a primary fluid flow of the work vehicle. The double-walled flow pipe may also include an outer tube surrounding the inner tube such that an annular passage is defined between the inner and outer tubes. The annular passage may be in flow communication with the fluid conduit. When a vacuum is applied to the annular passage, the aspirated airflow may be drawn through the fluid conduit from the pre-cleaner and directed to the annular passage. The aspirated airflow flows through the annular passage as the primary fluid flow is being directed through the inner tube.

  • Patent number: 10781112
    Abstract: The present invention provides a dehydrogenation tank. An atomization spray is disposed at the center of the upper part of the dehydrogenation tank, and flow stirring modules used for stirring a flowing solution are respectively disposed at the middle and the bottom of the dehydrogenation tank. Each of the two flow stirring modules includes at least two layers of flow stirring meshes. By means of disposing the atomizing spray and the flow stirring modules in the dehydrogenation tank, the TRO solution flowing into the dehydrogenation tank are fully stirred, so that hydrogen gas mixed with the TRO solution is able to diffuse out fully and rapidly, thereby increasing dehydrogenation efficiency as well as reducing volume of the dehydrogenation tank. In addition, the present invention also provides a ballast water treatment system having the dehydrogenation tank.

  • Patent number: 10773196
    Abstract: A gluing method of a filter cartridge includes: preparing a filter core and a filter frame; disposing them in a lower mold with the filter frame under the filter core; filling glue on top of the lower mold, extending the glue to a gluing segment of the filter frame and an outer surface of the filter core; pressing down an upper mold toward the lower mold to cut the glue into an inner glue segment and an outer glue segment. The inner glue segment is pressed in between the filter frame and the filter core, coated around the gluing segment to increase adhering area. Pressure from the upper mold enhances the adhering effect. The cutting removes surplus glue and the glue is formed into a desired shape, thus the method is quick, accurate and consistent.

  • Patent number: 10737209
    Abstract: Systems and methods for detecting a missing coalescing element in a CV system are described. In some arrangements, the described systems and methods prevent the assembly and/or re-assembly of the CV system without an appropriate coalescing element positioned within the CV system housing (e.g., during a coalescing element service operation). In some arrangements, the coalescing element depresses a spring-loaded component of a shaft that provides flow of bypass gases to the CV system. If the spring-loaded component is not depressed, significant restriction is introduced to the CV system, and an on-board-diagnostic system may detect high-crankcase pressure through existing crankcase pressure sensors and de-rate the internal combustion engine. In other arrangements, a spring-loaded mechanism within the shaft prevents a housing cover (e.g., a lid to the housing of the CV system) from being repositioned when a coalescing element is not installed within the housing.

  • Patent number: 10729993
    Abstract: A filtration filter comprises a porous film including a central film portion having a plurality of through holes and an outer edge portion adjacent to the central film portion. The porous film portion lies in a flat plane in the absence of a force being applied to the central portion of the central film portion. A frame holds the outer edge portion of the porous film in such a manner that when a force is applied to the central film portion in a first direction, the central film portion moves in the first direction relative to the flat plane and the outer edge portion moves in a second direction, opposite to the first direction, relative to the flat plane. In this way stresses applied to the porous film during a filtering operation are reduced.

  • Patent number: 10718510
    Abstract: The group of inventions refers to heat exchange machinery. The device includes a tank with an outlet fitting and a steam source, a deaerator column with a cover and water inlet and vapor blowdown fittings located on the same, containing lower and upper deaeration sections. Each section includes pressure and distribution trays forming a jet chamber in the space between them, and random element packing. Deaeration sections are separated by a hydraulic seal formed by the edge of the upper section pressure tray and the projection connected to the deaerator column cover. The water inlet and vapor blowdown fittings are located inside the hydraulic seal projection with openings in it. The lower edges of the openings are located higher than the upper edge of the hydraulic seal by a value exceeding the sum of overflow height of the coolant over the edge and hydraulic resistance of the hydraulic seal channel.
