100% Pure Teflon PTFE wire mesh demister grid F4 carriage

Teflon grid demister net block configuration diagram showing 1-- screen; 2-- fixed pitch lever; 3-- grille mesh demister mainly by wire mesh, wire mesh grille mesh block composition and support means fixing blocks constituting a screen, a screen for a variety of materials of liquid filters, liquid filters are made of metal wire or non-metallic filaments. Liquid filters of non-wire by a multi-strand non-metallic fibers twisted together, can be single-stranded non-metallic wire such as polypropylene PP and PTFE Teflon and other plastics can also be used mixed gas-liquid filtration network, such as metals and engineering plastics such as polypropylene or polytetrafluoroethylene mixed metal mixed with a variety of fiber lines and so on. In addition to the production of wire mesh demister when used in liquid filters and the support means by my factory according to the Ministry of Chemical Industry HG / T21618-1998 wire mesh demister standards (demister thickness and density can also be based on user demand produce). I plant the production of wire mesh demister filter out not only suspended in a stream of large liquid foam, and can filter out small and tiny liquid foam is widely used in chemical, petroleum, towers, pressure vessels and other industries The gas-liquid separation device. Second, wire mesh demister type Example: DN2000MM, H150MM, liquid filters in the form of SP-type, made of 304 grid, the support material is Q235-A coat type screen demister marked: HG / T21618-1998 screen demister S 2000-150SP304 / Q235-A. Example II: DN4000MM, H100MM, liquid filters in the form of DP-type, made of 316L, grille, support material for the download type screen demister 304 mark: HG / T21618-1998 mesh mist eliminator X4000-100DP316L / 304. Note: Top entry and download type selection screen demister: when the hole opened in the screen in addition to the above location demister or no flange into the hole and have equipment, the choice of coat type wire mesh demister; When the benefits of open hole in the screen removed in a demister, the choice of downloading type screen demister. Figure 1-1 Top entry screen demister Figure 1-2 download type wire mesh demister three mesh demister principle in ordinary chemical operation encountered gas dispersed droplets of a diameter of about 0.1 ~ 5000μm. Usually more than 100μm diameter particles settling velocity faster because its separation problem is easily solved. Typically 50μm diameter larger than the droplets, gravity sedimentation separation can be used; 5μm droplets above available inertial impaction and centrifugation; For smaller fine mist will have managed to aggregate to form larger particles, or fiber filter and Electrostatic mist. Screen demister, which is mainly used for the separation diameter greater than 3μm ~ 5μm droplets, works as shown. When the gas with mist rising at a constant speed through the frame on the wire mesh grid, due to the inertia of the mist rising, making the mist collide with filaments attached to the surface of the filament. Mist on the filament surface is further diffusion and gravitational settling mist itself, so that the formation of larger droplets mist flow along the filament to its interleaving. Since the filament wettability, capillary action and surface tension of the liquid filaments so that the droplets growing, until its own force of gravity over rising gas buoyancy and surface tension of the liquid when it is separated and fall, flow downstream equipment to container. As long as gas velocity and other conditions are selected properly, the gas except through screen after the demister, which demister efficiency can reach more than 97%, can achieve complete removal of mist purposes. Fourth, use wire mesh screen demister operations other demister (mist) for separating entrained liquid droplets gas column, in order to ensure there is mass transfer efficiency, reduce material loss of value and improve the tower of the compressor , and more generally set up in the overhead screen demister. Can effectively remove 3--5um droplets between trays if set demister, not only to ensure the efficiency of the mass transfer tray can also reduce board spacing. It is mainly used in wire mesh demister gas-liquid separation. Also for the air filters for gas separation. In addition, demister screen can be used as instruments of all kinds of industrial instrumentation buffer to prevent electronic jammers and other radio interference. Fifth, wire mesh demister standard HG5-1404-81, HG5-1405-81, HG5-1406-81 HG5-1404-81 riser type, HG5-1405-81 Reducer, HG5-1406-81 full bore type wire mesh demister diameter from 300mm to 6400mm, 100mm and 150mm have two kinds of screen height. Just type number and material used when ordering. Tag example: HG5-1406-81-11,304 / 304 means that the grille and screen are made of 304 stainless steel, full bore type coat type, diameter 1600mm, height 100mm screen demister. HG / T21618-1998 wire mesh demister new standards into the riser pipe, reducer type and full diameter type of installation is available; and made a SP, HP, DP and HR four kinds of grid and expanded material selection species; and an increase in the sizes of the interval density setting. Tag example: HG / T21618 wire mesh demister S 1600-100 SP 304/304 means that the grille and screen are made of 304 stainless steel, coat type, diameter 1600mm, height 100mm, net type with SP screen demister device. HG / T21586-98 drawer mesh demister This standard mainly applies to situations often need to be cleaned or replaced except foam element, such as drying tower and the absorption tower sulfuric acid plant. Its choice of the nominal diameter range of DN300mm ~ DN5000mm 56 species. When ordering simply provide the figure number and selection of materials (including 316L, NS-80 and RS-2 for the sulfuric acid plant selection screen material). Tag example: HG / T21586.11-98WME-1600-100NS-80 / Q235-A means that the screen using NS-80, carbon steel grille with a diameter of 1600mm, height 100mm drawer type wire mesh demister six , screen demister parameter HG / T21618-1998 Used wire mesh demister gas-liquid filter technical parameters type code volume weight kg / m3 specific surface area of ??m / m3 porosity ε SP 168 529.6 0.9788 HP 128 403.5 0.9839 DP 186 625.5 0.9765 HR 134 291.6 0.9832 standard gas-liquid filter technical parameters wire diameter dw (mm) web width allows (mm) Bulk density ρ (㎏m3) surface area α (m / m3) void ratio ε Biansi round wire ± 20 150 Biansi round wire 0.981 0.1 × 0.4 0.23 475 320 high penetration type liquid filters technical parameters wire diameter dw (mm) net wide to allow (mm) Bulk density ρ (㎏m3) surface area α (m / m3) porosity ε Biansi round wire ± 20 98 Biansi round wire 0.9875 0.1 × 0.4 0.23 313 217-efficient gas-liquid filter technical parameters wire diameter dw (mm) net wide to allow (mm) Bulk density ρ (㎏m3) ratio surface area α (m / m3) void ratio ε Biansi round wire ± 20 182 Biansi round wire 0.977 0.1 × 0.28 0.19 626 484 VII, non-standard mesh demister Wire mesh demister is widely used, I can plant for the user to produce a variety of special shapes and types of import substitution demister. Such as wave type, embedded, exterior type, SWD1 type, square, rectangular and irregular, and so on. Demister thickness and density can be based on user needs production. Where the choice of plant product users, if necessary, I plant can provide supporting demister installation diagram and parts diagram support. Eight, wire mesh demister Wire mesh demister Material Used 316 and 316L austenitic stainless steel is used. With standard 304 stainless steel as compared to 316 and 316L of sulfuric acid, sulfide solution, sodium and manganese salt solution, hydrochloric acid and phosphoric acid corrosion resistance are superior to 304, acetic acid, formic acid, formic acid and hot alkaline solution also it has good corrosion resistance. Such low carbon steel, and therefore may not be subjected to heat treatment after welding, especially called ultra-low carbon stainless steel 316L, resistance to intergranular corrosion better than 316, so better corrosion resistance.
