A liquid separator for separating liquid out of a gas/liquid mixture, including an inlet, an outlet, a flow path connecting the inlet to the outlet and at least one separating device arranged in the flow path, the liquid separator being designed and embodied with simple structure and a compact construction to enable reliable separation of liquids in such a way that the separating device has a fabric portion for liquid separation through which the flow path passes, the fabric portion being arranged at an angle of 1° to 15° relative to the main flow direction in the separating device.

Systems, assemblies, and methods to enhance the efficiency of operation of a gas turbine engine may include a turbine housing positioned to at least partially enclose the gas turbine engine, and a filtration assembly connected to the turbine housing to supply at least partially filtered intake air to an inlet assembly associated with the gas turbine engine. The filtration assembly may include a pre-cleaner including one or more inertial separators configured to separate a first portion of particles and/or liquid from ambient air supplied to the gas turbine engine, thereby to provide at least partially filtered intake air, and one or more filters positioned downstream of the pre-cleaner to separate a second portion of the particles and/or liquid from the at least partially filtered intake air.

A method for the dry filtration of a gas flow carrying foreign objects, a filter device for cleaning off waste gas resulting from additive manufacturing technologies, comprises feeding a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side; feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface; such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form oxide-containing foreign objects.

An incubator for cell and tissue culture under controlled atmospheric conditions has a primary air flow control device that forms a primary, preferably laminar flow, air veil across an opening that allows access to the cells or tissue cultures disposed within the incubator. Preferably, most if not all of the air in the primary (laminar flow) air veil is recirculated, and a secondary air flow control device is used that forms a secondary, preferably laminar flow, air veil between the primary (laminar flow) air veil and a user of the incubator.

A system, as well as associated methods, for increasing the efficiency of a gas turbine including an inlet assembly and a compressor may include a housing configured to channel airstream towards the inlet assembly, an air treatment module positioned at a proximal end the housing, and at least one air conditioning module mounted downstream of the air treatment module for adjusting the temperature of the airstream entering the compressor. The air treatment module may include a plurality of inlet air filters and at least one blower configured to pressurize the air entering the air treatment module.

Disclosed is a gas fuel supply system including a main fuel inlet, a pressure regulating valve, a pneumatically controlled shutoff bleeder valve and a main fuel outlet that are connected through pipes. The pneumatically controlled shutoff bleeder valve includes a pneumatic control valve and a shutoff bleeder valve. The shutoff bleeder valve is configured to open or close a gas fuel delivery passage from the main fuel inlet to the main fuel outlet, or configured to discharge the gas fuel in the pipe. The pneumatic control valve is configured to control the shutoff bleeder valve to be in a desired state. The gas fuel supply system does not need connection to an additional gas source, and the gas supply stability is improved.

A detoxification device for removing pathogens from air within an environment. The detoxification device may include a filtration media for catching and retaining particles larger than about 0.3 micrometers (μm) with an efficiency of at least 99%. The detoxification device may also include a heating element having a metallic foam. The heating element may be heated upon application of an electrical current to the heating element. The heating element may, upon being heated, heat the filtration media to a target temperature that is effective to kill a pathogen.

An apparatus for collecting a by-product, includes: a chamber provided with a gas inlet and a gas outlet and having an internal space; a heater disposed on the gas inlet side of the internal space within the chamber and varying a heating temperature in time series; a vortex forming member disposed around the heater; a plurality of first collecting members disposed below the heater; a second collecting member disposed below the first collecting member so that a plurality of second collecting members intersect each other; and a third collecting member disposed on the gas outlet side of the internal space within the chamber.

An air filter and air purification technology including a frame encompassing a filter channel and a filter medium across the filter channel. The air filter and air purification technology also include one or more electrical heating components, placed in the filter channel and configured to heat the filter medium and/or air in the filter channel. Thus, the air filter has a heating function, and can heat the filter medium and the air in the filter channel according to actual working conditions and/or operations, so as to prevent moisture in the air from affecting the filtering efficiency of the filter medium. The air filter and air purification technology have the characteristics of enhancing the filtering effects and improving the service life of the filter.

A method for manufacturing an electrified air filter for an intake system of an engine of a vehicle; the manufacturing method comprises the steps of: manufacturing an outer reinforcement mesh and an inner reinforcement mesh; manufacturing a filtering material panel; placing the reinforcement meshes on opposite surfaces of the filtering material panel so as to form a unit; bending the unit in a wave shape; and coupling the wave-shaped unit to a peripheral frame; externally coating the wires of said outer reinforcement mesh with an outer insulation; placing two strips of conductive metal material at the opposite ends of the outer reinforcement mesh; welding the two strips to the ends of the warp wires; and cutting each strip by means of through cuts so as to create spaces and hence obtain from the strip a succession of collectors that are separate from one another.
