Regarding the air compressors in the demineralized water plant
Thread Content
Regarding air compressors: The equipment in the water treatment workshop that requires compressed air includes multi-media filters, mixed-bed reactors, ultrafiltration systems, and pneumatic valves. For the backwashing of multi-media filters, a Roots blower can be used; an air pressure of 0.05 MPa is sufficient. Compressed air with a pressure of 0.1–0.15 MPa is used for mixing beds and blending fats, while compressed air at 0.1 MPA is used for ultrafiltration. Except that the multi-media filter uses a Roots blower, what kind of equipment should be used as the air source (power source) for other devices? Should a piston air compressor or a screw air compressor be used? Please explain, experts
For the power source of equipment such as mixed-bed systems and ultrafiltration units, either piston air compressors or screw air compressors can be chosen. Piston air compressors are generally suitable for applications with modest requirements, involving low to medium flow rates and pressures. They have a lower cost, but generate more noise and require frequent maintenance ； Screw air compressors are suitable for continuous operation, high flow rates, and stable pressure requirements. Although the initial investment is high, they offer steady operation, low noise levels, and minimal maintenance needs. Considering both efficiency and stability, screw air compressors are generally recommended, unless there are special requirements. .
Screw air compressors will definitely be used. Piston air compressors, with their high energy consumption and low efficiency, have been gradually phased out by the market. Additionally, screw blowers can also be used in multi-media filters. However, caution should be exercised when choosing air-suspended or magnetically suspended blowers, as the current level of technological maturity for these two types of blowers does not yet allow for a high degree of product stability.
