A domestic knowledge-based company has produced a cellulose cartridge filter that can improve a turbine’s performance by eliminating oil varnish.
Turbine oil lubricates bearings, gears and couplings, transfers heat and cools bearings, improves hydraulic performance and increases protection against rust and wear.
The depth cartridge filter produced by Behin Palaye Sharif Company (also known as Behpal Sharif) can be used in different industries to remove varnish from turbine, hydraulic, gear and transformer oils, the news portal of Vice Presidency for Science and Technology reported.
The use of nanoparticles for improving varnish removal, the ability to lower pressure on filters, tenfold cost reduction, absorption of water, varnish and compounds resulting from oil oxidation, customized production based on filtration precision required by the customer and chemical resistance against solvents, acids and weak bases are among the main features of the domestic cellulose cartridge filters.
Anti-oxidation, anti-corrosion, separation of water and air, and non-foaming are important physical and chemical properties of the domestic cellulose turbine oil filters.
Varnish is one of the harmful products resulting from oil degradation. It is created from insoluble particles and sometimes organic solutions (such as viscous oxides) and carbonaceous materials found in the oil.
As a result of the reduction of oil temperature to below 50 degrees Celsius and the condensation of soluble and insoluble particles, the varnish is created in the form of hard and brown deposits. The presence of varnish in oil clogs the filter, contaminates new oil, prevents heat transfer in the oil cooler and increases the temperature of turbine bearings. In order to control oil quality, filtration is used to prevent the entry of pollutants.
Filters are available in two depth and surface forms. Cellulose depth filters are used in turbine oil purification and nanofibers in these filters improve the efficiency of varnish removal from oil.
As normal filters are made of paper, the cellulose filter also curbs paper consumption.
Knowledge-Based Plasma Treatment Device
A knowledge-based company has produced wastewater treatment equipment using plasma and cavitation technology that purifies different types of wastewater for reclamation.
It can be used for the removal and neutralization of organic pollutants in industrial, mining, household and other wastewaters, purification of hospital effluents containing toxic compounds and treatment of contaminated and toxic water with heavy metals and microorganisms.
The equipment is produced by Pishro Fanavar Tav Asia (also known as Panta Plasma) with the support of the Iran Nanotechnology Innovation Council, the news portal of Vice Presidency for Science and Technology reported.
The company claims that the facility eliminates all types of harmful microorganisms, polluting organic compounds and heavy metals in wastewater.
The ability to destroy stable materials, using limited space for the purification process, avoiding the use of chemicals, lowering cost compared with counterparts, removing heavy metals and reducing sludge volume during treatment are among the advantages of the new facility, the company says.
The blending of plasma and cavitation technologies in the equipment reportedly results in more efficient purification compared to other systems.
Plasma technology is the use of high-voltage electric discharge by creating high-energy points in water using methods such as arc discharge, glow discharge and dark discharge in a pulsed manner without increasing the temperature of the fluid, which will reduce energy consumption and increase discharge power in a shorter time compared with other methods.
The cavitation technology helps form macro/ micro cavities by using cavitation modules (orifice pellet, venturi, rotary and vortex) and creates a pressure difference. With the explosion of these cavities, high energy points are created in the fluid.
The pulsed plasma in the new facility eliminates pollutants by creating an electrical discharge in the water. The company said it was able to boost efficiency by synergizing plasma and cavitation technologies using combined geometry and controlling specific conditions.
