Covering Ball is injection process. Other is foaming process. Owing to Injected cover ball’s weight is very light, it is very easy to wash way by strong water flow. Therefore, our company’s technical staffs have placed one solid steel ball inside the sphere. This change has not only increase the stability of the center of gravity, but also avoid of be blown way by strong wind. The overlapped edge will short Floating cover’s void fraction so as to reduce heat loss and evaporation rate.Finally. The combination of aerators and mixers with Floating cover leads to improved biological treatment performance and consistent high-quality effluent.As for Foamed Liquid surface cover ball, due to the processing is foaming technology, it is very easy to soften under long time exposure.
Igel Ball Biological Filter Media have an extremely high surface area for bacteria to colonize. It is mainly apply in Aquarium. In recent years, Bio ball’s using becomes more and more popular in oversea market.
This product is made of PP and foaming agent. In the moment of Hot summer’s coming, Rapid water evaporation and water pollution have always been the biggest headaches for Reservoir, aquaculture field.”How to reduce water evaporation and pollution” will become the most important problem. Diamond Floating ball is the ideal product. When this ball is floating on the water, those balls automatically arrange themselves into a close packed formation over 99% of the surface area. This high surface coverage provides an extremely effective barrier and significantly reduces the mass and heat transfer mechanisms operating between the liquid and surrounding environment.Low condutivity results in an extremely effective thermal insulation barrier. It is not just a ball, but a solution to a problem. Most of our successful installations have resulted from working closely with customers, sharing our ideas and experience and tailoring a solution to meet their specific requirements.
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 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.
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.
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.
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 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.
