Mannheimer innovative filtration solutions improve compressor energy efficiency
Energy costs are rising sharply, and carbon dioxide emissions are also rising. This has brought great impact on all aspects of our lives and has aroused great concern in society. In fact, energy efficiency has always been a closely related development goal for compressors used to compress air. The above-mentioned trend now makes this goal particularly important. It is important to keep in mind that improvements to the filtration system can significantly reduce energy consumption, thereby reducing costs and carbon dioxide emissions. Today, industrial and construction companies generally use oil-injected screw compressors to supply compressed air of various quality standards. The energy required for compressor operation accounts for approximately 75% of operating costs. As energy prices continue to rise, energy-saving measures have become more important. Compressor manufacturers are developing new systems to improve the conversion of mechanical or electrical energy to thermal energy and to increase compressed air energy. In order to achieve high energy efficiency, the performance of all fixed parts of the compressor must be considered in conjunction with air purifiers, oil filters, and oil and gas separators. These three components form an interactive filter chain. High-efficiency filter development tools For more than 40 years, Man Hummel has been involved in the development and production of oil and gas separators for compressed air systems. Its research and development in this area is focused on reducing residual oil, extending service life and improving energy efficiency. Man Hummel uses modern technology to achieve these development goals. In the early stages of development, MANN+HUMMEL has adopted measures to reduce pressure drop, such as the use of computer fluid dynamics simulation tools. Different colors are used to indicate various flow rates. The flow rate increases and the pressure drop increases, resulting in unnecessary energy loss. Change the design to choose the flow rate range for the discovery. The application of corresponding expertise can achieve significant results in a very short period of time. Even filter and filter media with tiny oil droplets or particles as small as submicron can affect energy efficiency. Simulating a dynamic separation process can significantly improve the filter. In the process, the main use of the simulation tools developed by MANN+HUMMEL, as well as the use of other simulation tools available on the market. These fundamental improvement measures are supported by the scientific achievements of the cooperation research project between Mann Hummel and renowned universities. These developments have improved the design and structure of the filter media, resulting in a significant reduction in pressure drop, improved filter accuracy and dirt holding capacity, and lower energy consumption. These development tools and technological improvements are used in compressor related filters and filtration systems. In this process, all the components have not only been improved, but the entire filter chain and the interaction filtering stage that are all connected in the system have also been improved. This requires parts and systems suppliers to have comprehensive expertise and be able to fully develop various types of filtration products. Although only minor adjustments are made to the system, it is possible to achieve high efficiency of the compressor and to maximize energy savings. Air filtration The first step in the compressor filter chain is the air purifier: it filters the inhaled ambient air and directs it to the compressor element. Even in this first step, efficiency can be improved. For example, with a pressure drop of 10 bar, the air purifier flow rate in a 50 hp compressor is about 5 m3/min, which saves about 36 euros (about 342 yuan) per year. FAD x delta (delta p, minimum pressure difference) x operating time x unit energy cost = cost savings 5.32 m3/min x 10 mbar x 4000 hx 0.1 €/kWh = 36 EUR (342 CNY)
