SS316L Metal Raschig Ring for tower packing

Metal Raschig ring is the oldest regular packing and is still used today for many applications in mass transfer applications but commonly for refilling existing columns.Friedrich Raschig invented the rings in the 1880s but did not patent them until the 1910s. Due to simple cylindrical shaped tube with an aspect ratio of 1:1, liquid liquid will move in the thousands of channels formed by the rings, coating the inside and outside surfaces, and eventually flowing to the bottom. Gas entering at the bottom will flow through the same paths formed by the rings, and will have time to contact and react with the liquid.However, Owing to metal Raschig ring’s inside is a cylinder with open ends, it is difficult to follow into Metal Raschig Ring’s inside for liquid. Finally, its mass transfer efficiency is lower than others. It has replaced by Metal Pall ring slowly.

liquid-vapor contacting component Bubble cap

The structure of the bubble cap tray is mainly composed of a blister (gas-liquid contact element), a gas riser, an overflow weir, a downcomer and a tray.The bubble tray is provided with a plurality of round holes on the tray plate, and each hole is welded with a short tube called a riser tube, and the tube is covered with a “hat” called a blister, and a plurality of strips are formed around the blister. Hole, during operation, the liquid flows from the upper tray through the downcomer into the lower tray, then flows laterally through the tray plate and flows into the next tray; the gas rises from the lower tray into the riser tube and passes through the annular passage. The strip holes of the blister flow into the liquid layer between the blister.

Metal wire mesh demister for droplet seperation

In many process operations the removal of entrained material in vapour flows is essential. Metal Wire Mesh Demister units is many used in separation of over 3-5 μm liquid droplet.When the foam with the fog rising at a rate of gas through a certain screen, due to the inertia of the role of fog rising foam, foam will collide with screen’s surface and attach to the its surface. When foam slowly forming a big droplet, the larger droplets to form fog foam flow along the filament between two wire junction points. Finally, once droplets weight exceeds its weight & gas liquid surface tension, droplets separated from the filaments.Metal Wire Mesh Demister was consist of Beam, Hold down bar, Hold Down plate,supporting plate,sealing plate,retaining ring and so on.It is widely used in chemical, petroleum, sulfate, medicine, light industry, metallurgy, machine, building, construction, aviation, shipping, environment protection and for fuel gas scrubber.

low aspect ratio cascade mini ring

Ceramic Cascade Mini Ring absorbs the characteristics of the ceramic Raschig ring and Pall ring. the tapered flanging on the end of Ceramic Cascade Mini ring is not only reduce air resistance,but also increase air flux. Due to its own asymmetric structure,it will increase the Directional probability when filling. Additionally, also change packing’s contacting way from linear to point. Point contacting provide more contacting area for gas passing, also promote packing’s surface liquid-film renew. Therefore, It is a kind of packing with high mass transfer efficiency.

Liquid collection redistributor

Liquid collector’s major function is collecting the liquid and re-distributing the gas. Usually, liquid collector is in the top of packing bed. The distance between liquid collector & packing bed is 150-200 mm.When the liquid falling down along with packing,due to upward gas’s speed is not same, gas’s speed toward center is big and toward tower wall is small. It is very easy to form wall flow phenomenon. In order avoid of wall flow phenomenon’s happened and improve mass transfer efficiency, we should install liquid collector or liquid re-distributor to improve liquid’s evenly distribution. Of course, according to different processing requirement, we can install one or many Liquid collectors in the different height’s position.

PP Suspend Ball Cage Ball Plastic Bio Floating Ball Biofilter media

It is also called Poriferous Ball-shaped suspend packing which was concentrated two technology’s advantage that is wastewater treatment & Bio-film Reactor. Outer structure is two net-shaped spheres, Inner structure is revolving sphere,PU sponge and so on.The mainly role is used in Bio-film carrier & intercept suspend granule. In wastewater processing project, it has big biological adhesion, large specific surface area, high porosity ratio, durable, not dissolve out pests, not cause secondary pollution, Anti-UV, strong hydrophilic.

Liquid-vapor seperating device Mist Eliminator

It is is a device often fitted to vapor liquid separator vessels to enhance the removal of liquid droplets entrained in a vapor stream.It is made out of aluminum, galvanized steel and stainless steel materials. When desulfurized flue gas passing through Metal Mist Eliminator at a certain speed, flue gas will be quickly change movement way. Due to the inertia and centrifugal’s driven, droplet collides with Vane and gather to form water flow. Finally, when droplet forms bigger ones,It will fall down. The most common process design for Mist eliminator is in a vertical gas flow, but it is also possible to install Mist Eliminator in the horizontal gas flow. The choice of vanes and design is influenced by the system pressure loss, the cleanability of the mist eliminator and the risk off clogging.The mist eliminator system consists of the mist eliminator body and a flushing system. Generally, it is composed of two-level demister body with different specifications, flushing water pipes, nozzles, supporting frames, supporting beams and related connections, fixing parts, and sealing parts.

VSP Metal Modified Rings

Metal mella ring, also named metal mellaring, is similar to teller rosette. it creates gas/liquid contact on easily wettable surfaces and promote theformation of droplets as the liquid cascades through the packing’s surface.The similar product is Topak designed by Seikow,Mellaring designed by sulzer and so on.VSP Metal Modified Rings Metal VSP Ring’s ligules that bends inside is not only increase opening pore area,but also increase air’s flux. Compared with Metal Pall ring, flux will increase 15-30%. Pressure drop will reduce 20-30%.

Animal Husbandry Equipment Pure Material Plastic Deodorant Net Wet Curtain

Net Wet Curtain is constructed by a series of plastic sheets assembled into a lattice structure, with its internals engineered to the geometry of honeycombs. This network structure provides a large contact area which allows even liquid distribution, augmenting liquid flow rate with minimum resistance. Its high surface area to volume ratio contributes to high mass transfer efficiency.
