摘要:
Apparatus (1) for additively manufacturing at least one three-dimensional object (2) by means of successive layerwise selective irradiation and consolidation of layers of build material (3) which can be consolidated by means of at least one energy beam (4), comprising: - a process chamber (7) in which a process gas stream chargeable or charged with non-consolidated particulate build material is generated during operation of the apparatus (1); - a streaming channel structure (16) comprising at least one streaming channel element (15) for a respective process gas stream the streaming channel element (15) communicating with a process gas stream inlet (9a) and/or a process gas stream outlet (9b) of the process chamber (7); - a particle separation device (18) configured to separate non-consolidated build material from the process gas stream streaming through the at least one streaming channel element (15).
摘要:
The invention permits, without the consumption of energy, emission of negative ions to purify the environment. In addition, the invention has biocidal action to eliminate microorganisms and bacteria. Furthermore, the invention emits infrared radiation to dry out walls, ceilings and objects in the room, thereby removing moisture. To those ends, the invention comprises a frame (1, 2) and a first body (3) that emits negative ions, which comprises a first anodized aluminium plate (7) and a second anodized aluminium plate (8), which are covered with a ceramic paint with silver-doped zeolites, which, in addition to emitting negative ions, constitutes a nanosilver-based biocidal compound. Said aluminium plates (7, 8) are heated uniformly by a wire (6) in order to emit infra-red radiation
摘要:
Methods of sequestering toxin particulates are described herein. In a primary processing chamber, a carbon source of toxin particulates may be combined with plasma from three plasma torches to form a first fluid mixture and vitrified toxin residue. Each torch may have a working gas including oxygen gas, water vapor, and carbon dioxide gas. The vitrified toxin residue is removed. The first fluid mixture may be cooled in a first heat exchange device to form a second fluid mixture. The second fluid mixture may contact a wet scrubber. The final product from the wet scrubber may be used as a fuel product.
摘要:
A filtration system is provided. The filtration system includes a filter media including a plurality of apertures defined therein, and an array of micropillars. Each micropillar is substantially aligned with one of the plurality of apertures and is configured to be repelled by particles of a predetermined substance entrained in a flow channeled through the filtration system.
