In recent years, with the advent of modern science, there has been a major shift in technology and industry, with developments that seek to achieve higher returns, lower costs, and less costly consumer spending. In the meantime, nanotechnology can be seen as the most significant development of technology and industry, as many of them are remembered as the industrial revolution of the new century. The lucky ones were no different in this regard, and this technology, with the help of the supporters, academics and partners of the prominent figures, has made significant advances that has made Iran one of the most prominent countries with this technology. It means one billionth and Nanotechnology is in fact the development of research and technology at atomic, molecular and macromolecular levels of approximately 1 to 100 nm in order to provide a basic understanding of phenomena and materials in the nano-scale, with the aim of creating and using structures, components and systems to Because of the small or average size, the properties of the properties and performance are the result of the search. In fact, by controlling the size of the material at a scale of 1-100 nanometers, we can receive special properties from the materials. Nanotechnology is central to all industries, especially in medicine, filtration, food, textiles, petroleum, petrochemicals, agriculture, and many other important industries. In the meantime, nanofiltration can be considered as a major achievement of nanoscale, which has had a significant effect on various industries. Filters are porous materials that are used in the process of separation or condensation. The filter feature is characterized by the presence of pores and faces with clear dimensions and dimensions, which is why the filter is a porous medium. The filters absorb a very large percentage of the filter volume, and the grid creates welds from the drill. Filters can be made of polymer or ceramic. Filtration or filtration is a process in which a liquid or gas (fluid) is passed due to the difference in pressure or difference between the electrical potential and the concentration of the filter. By performing a filtration of particles Which pass through the dimensions of the coil filters, and particles larger in size, are separated from the fluid and are behind the filter. Many factors play a role in filtration, which is effective in choosing the type of filter and its function: The size of the filter cavity: As stated above, materials of a larger size than the filter cavity remain behind it, and Ab As a result, appropriate filters should be used to reduce the size of the particles. The amount of particles that remain behind the filter: the particles behind the filter remain constant over time.
This can block filter rents. Because of this, you have to replace the filter or remove it after a certain period of time. This issue, which is known as the filter eclipse, is of great importance. Because switching or even cleaning the filter is cost-effective. Filtration is important in many industries. The filters used in the industry are usually of the kind of filter bag, which has a relatively important role to play. The bag filter is a series of hermetically sealed hinges connected to holders called a cage, passing through the gas from the inlet valve and moving towards the outlet of the filter, the dust of the outer surface of the cases, then in The specified time intervals are applied to the airflow, the dust on the bag, and the bottom of the happer is poured into the filter so that the dust is separated from the gas. Another equipment widely used for desalination of the air in the cement industry is the buffers .These types of filters have high drip efficiencies, which according to the kind of dust up to 99.9% open A factor that limits its use is the gas temperature entering it, with new advances in fiber cladding, the use of which has become widespread. Nanotechnology has also been able to influence this trend. Let’s talk about some of the most commonly used filters in the filter cavity. If we can minimize the pore size to allow smaller particles to be trapped, we can have at least a drop in pressure compared to conventional filters, so that systems with higher efficiency and Of course, better filtration operations are needed. Also, if filtration is performed at the surface of the filter, it will definitely result in a higher lifetime filtration, resulting in a loss of cost due to the pulses that the device employs and the filters are resuscitated.
