A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu—Cl Cycle. Non-pure water is used as the feedstock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feedstock of industrial processes. The direct usage of this water can significantly reduce water supply costs.

The invention discloses a liquefaction device of hard bone, comprising: outer cavity having upper end detachably sealed with upper cover, and lower end openable/closable sealed with lower sealing cover, first liquefaction cavity coaxially slidably disposed in outer cavity, stainless steel cage disposed coaxially in first liquefaction cavity, second liquefaction cavity fixed to outer sidewall of outer cavity such that lower end portion of outer cavity is located in second liquefaction cavity. The invention also provides a method for co-production of bone collagen polypeptide and ultrafine bone powder based on liquefaction device, including: selecting hard bones, crushing; performing first-stage and second-stage liquefaction to obtain liquid phase and solid phase; centrifuging, concentrating, drying liquid phase to obtain bone collagen polypeptide; drying, coarsely and superfine pulverizing solid phase to obtain ultrafine bone powder. The invention has effects of simplifying process, improving production efficiency, and reducing production and equipment investments.

The present invention comprises: a cylindrical pipe (314) that has a cylindrical shape about an axis (O) extending in the horizontal direction and has a space internally extending in the direction of the axis (O); steam inlets (31, 32) which are provided at the bottom of the cylindrical pipe (314) and through which steam is introduced; a steam outlet (33) that is opened from an end of the cylindrical pipe (314) in the axis (O) direction toward the axis (O) direction for exhausting steam from the cylindrical pipe (314); and a moisture separation element (315) that is provided in the cylindrical pipe (314) between the steam inlets (31, 32) and the steam outlet (33) and has a plurality of vanes for separating moisture from steam by passing the steam through the vanes.

A system for producing steam includes a steam generator with steam output; a membrane filtration system in fluid communication with the steam output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from steam.

A centrifugal filtration device is provided, including: a casing, including an inlet passage and an outlet passage which are arranged on an extension direction; a plurality of blades, extending spirally on an inner circumferential wall of the inlet passage relative to the extension direction; a guiding mechanism, including a first tapering portion tapered in a direction toward the inlet passage, disposed in the casing and located between the plurality of blades and the outlet passage.

Provided are a chevron vane that traps and removes droplets contained in steam and a moisture separator including the same. The chevron vane for trapping and removing droplets contained in steam includes a main frame group including multiple main frames arranged in a flow direction of steam and pivotably connected to each other, and a collection vane group mounted on the main frame group and including multiple collection vanes for trapping droplets contained in the steam.

A steam generator system for a cooking appliance includes an in-line heating element coupled to a heating tube, wherein water from a water reservoir is gravitationally fed into the heating tube for heating by the in-line heating element to produce a hot water and steam mixture. A first supply line is coupled to the heating tube to carry the mixture to a separator without the need for moving or complex pump parts. The separator separates steam and hot water from the mixture of the two. A second supply line is coupled to the separator at a first end and opens into the cooking cavity of the cooking appliance at a second end. The second supply line is configured to supply steam separated at the separator to the cooking cavity via a steam outlet disposed in the cooking cavity.
