Cleanliness requirements are addressed by compressed air filters

For compressed air pipeline, in order to avoid affecting the operation of the whole station or other air compressor units during maintenance, and to prevent the backflow of compressed air reliably during maintenance, a cut-off valve must be installed between the unit and the gas storage tank. In order to avoid affecting the gas consumption during the maintenance of the filter, spare pipelines should be set on the pipeline of each filter, and the branch pipelines must be connected from the top of the main road to avoid the condensed water in the pipeline flowing down to the compressor unit.

When the underground pipeline passes through the main road surface, the buried depth of the pipe top shall be no less than 0.7m, and the installation position and surface size of the secondary road surface shall be no less than 0.4m pressure and flow meter, which shall enable the operator to see the indicated pressure clearly. Air compressor exhaust compressed air is not clean, in addition to containing water (including steam, condensate) and suspended matter, and oil (including oil mist, oil vapor). These pollutants are adverse to improving production efficiency, reducing operating cost and improving product quality, so it is necessary to carry out drying and purification treatment.

The ground atmosphere is a mixture of gases, including nitrogen 78%, oxygen 21%, argon 0.93%, carbon dioxide 0.03%, neon 0.0018%, in addition to other inert gases, ozone, water vapor and dust. Pressure, flow requirements: any need for compressed air occasions of compressed air pressure and flow are required. The prevailing pressure is around 0.7MPa (g). In some special occasions such as glass industry, the pressure of compressed air may be about 0.2-0.4 MPa (g); In some military enterprises, the pressure of compressed air may be dozens of MPa.

There are a variety of air compressors on the market to meet these requirements. Cleanliness requirements (relatively complex, including: solid matter, oil mist, microorganism, harmful gas, etc.) : to be solved by compressed air filter. Quality issues because the quality of the filter material and the filter element is very important, as are the compressed air ducts used. Production enterprise reputation and service whether the production enterprise abide by the promise, have follow-up service and quality assurance ability. The enterprise technical strength enterprise must have the unceasing renewal product technical ability and the production capacity and so on, and can guarantee the product quality stability.

Due to the different characteristics of compressed air system and applicable energy-saving technologies, energy-saving transformation cannot be carried out blindly in order to improve the success rate of transformation. On the basis of comprehensive analysis, test and evaluation of the whole system, it is particularly important to choose appropriate energy-saving measures. By investigating the use of compressed air in a large number of industrial enterprises, the author analyzes and discusses the characteristics and application scope of some existing and emerging energy-saving technologies.
