Today, sintered filters are utilized more and more, but do you know why these metal filters are slowly replacing the prior generation of filter elements? Yes, it must be that the sintered filter element has many irreplaceable features, and the cost and the cost be cheaper. So If you should be interested to understand more information, please continue to read following.
What Is just a Filter ?
Filter can be an indispensable device for conveying media pipelines, usually installed in pressure relief valve, water level valve, square filter and other equipment at the inlet end of the equipment Sintered Metal Filter. The filter consists of cylinder body, stainless filter mesh, sewage part, transmission device and electrical control part. After the water to be treated passes through the filter cartridge of the filter mesh, its impurities are blocked. When cleaning is necessary, as long as the detachable filter cartridge is applied for and reloaded after treatment, it's therefore extremely convenient to use and maintain.
What Is the Working Principle of Sintered Metal Filter ?Sintered metal filters are efficient, two-dimensional, filter type, and particles are collected at first glance of the medium. The correct choice of media grade must balance the needs of filtration applications for particle retention, pressure drop, and backwash capability. You will find basically three process factors to take into account: the velocity of the fluid through the filter medium, the viscosity of the fluid, and the particle properties. Important particle properties are particle shape, size, and density. Hard, regular-shaped particles that form incompressible cakes, such as FCC catalysts, are perfect for surface filtration.
The filtration operation is dependant on a constant flow rate, increasing the pressure drop before terminal pressure drop is reached. The last condition is likely to be reached once the catalyst cake thickness is increased to the level where in actuality the fluid flow pressure drop is maximal for a given flow and viscosity condition. The filter is then backwashed by pressurizing the filter with gas, followed with a quick opening of the backwash discharge valve. This backwashing procedure produces an instantaneous high reverse differential pressure, that may effectively remove solids from the medium surface. The reverse flow of clean liquid (filtrate) through the medium helps remove solids and flush them out from the filter.
History of Filters
1000s of years ago, the ancient Egyptians used the initial ceramic filters made of porous clay pots. Experiments in seawater desalination in the 17th century generated the creation of multi-layer sand filters. Nobel-prize laureate Richard Zsigmondy invented the initial membrane filter and ultra-fine membrane filter in 1922. In 2010, the nanotechnology filter was introduced. Until today, sintered metal filters are widely used in all walks of life, and play an irreplaceable role in production and life.
Applications
With the development of economy and the needs of production and life, filter has been used in various fields for the advantages. In this part, we list some for you.
Beverage Industry
The strategy of making carbonated water by injecting carbon dioxide into water was first discovered by an Englishman, Joseph Priestley, in the late 18th century, while hanging a dish of distilled water over a keg of beer in a brewery. The oil of sulfuric acid is dropped onto chalk to make carbon dioxide gas, that will be dissolved into the water in a mixing bowl. Later, Swedish chemist Torben Bergman invented a power generator that used sulfuric acid to extract carbonated water from chalk. Carbonated water is obviously made utilizing a soda siphon or perhaps a home carbonation system or by dropping dry ice into the water. Food-grade carbon dioxide used to carbonate beverages typically comes from ammonia plants.
At present, the sintered stainless filter, such as porous sparer, is popular to spurge gas into water. The porous sparer ensures the distribution of the gas in the liquid through tens and thousands of tiny pores. The sparer produces smaller but more bubbles compared to the drilled tube and other sparging methods. The outer lining of the porous sparer has tens and thousands of holes, causing a wide range of gas to pass through a specific location in the liquid. So carbon dioxide may be dissolved into water evenly.
