Analysis of Air Compressor Pressure Selection Standard in Glass Industry

due to the particularity of the production process, the pressure demand for compressed air in the glass manufacturing industry presents multi-level characteristics. According to the technical requirements of key processes such as glass melting, forming and annealing, the pressure configuration of air compressor shall follow the following professional standards:

1. core process pressure requirements

  1. raw material conveying system
    • application Scenarios powder pneumatic conveying, weighing and mixing
    • pressure range: 0.4-0.6MPa
    • technical Requirements: It is necessary to configure a pressure stabilizing air storage tank to ensure that the pressure fluctuation of the air supply is ≤ ± 0.05MPa and to avoid intermittent powder delivery.
  2. Glass forming equipment
    • application Scenarios pneumatic control of feeder and determinant machine
    • pressure range: 0.6-0.8MPa
    • accuracy requirements precision pressure reducing valve is adopted to control the working pressure fluctuation within ± 0.02MPa to ensure the precision of glass droplet shaping
  3. annealing kiln cooling system
    • application Scenarios: Air cooling, stress relief
    • pressure range: 0.3-0.5MPa
    • flow characteristics: A frequency conversion fan shall be configured to dynamically adjust the air volume according to the annealing curve to ensure that the glass ribbon cooling rate deviation is less than or equal to 5 ℃/h.

2. special process pressure requirements

  1. coating process
    • application Scenarios: Auxiliary air supply for vacuum coating machine
    • pressure range: 0.2-0.4MPa (purified)
    • cleanliness requirements: Three-stage filtration system shall be configured to ensure oil content ≤ 0.01 mg/m & sup3; to avoid membrane pollution
  2. glass deep processing
    • application Scenarios CNC engraving, tempering furnace pneumatic components
    • pressure range: 0.5-0.7MPa
    • instantaneous flow: Need to meet the requirements of rapid start-stop of engraving head, with peak flow reaching 150% of base flow.

3. system configuration optimization recommendations

  1. graded gas supply scheme
    • the pressure of the main gas supply pipe network is set to 0.8MPa, which is distributed to each gas unit through the branch pipe pressure reducing valve.
    • Key equipment (such as line machine) is equipped with independent gas storage tank, with capacity ≥ 1m & sup3; and buffer time ≥ 30 seconds
  2. energy efficiency management measures
    • selection of two-stage compression air compressor, energy saving 15%-20% than single-stage unit
    • in the gas consumption scenario below 0.4MPa, the low-pressure fan is used instead of the air compressor, and the overall energy efficiency is improved by 30%.
  3. Safety protection design
    • the air compressor station near the glass melting furnace shall be provided with explosion-proof wall, with fire resistance limit ≥ 3 hours
    • the compressed air pipeline is made of stainless steel to avoid metal dust pollution in high temperature environment

4. industry application practice

typical glass enterprise air compressor configuration case:

  • float glass production line: Equipped with 3 0.8MPa screw air compressors (2 for use and 1 for standby), with a total air supply of 120m & sup3;/min
  • photovoltaic glass deep processing line: 0.6MPa centrifugal air compressor + 0.4MPa low-pressure fan combined for air supply, with annual electricity saving of 800000 kWh
  • pharmaceutical glass vial: The key station is equipped with 0.7MPa oil-free air compressor to ensure compliance with GMP cleanliness requirements

enterprises should establish a three-dimensional matching model of compressed air pressure-flow-cleanliness according to specific process requirements. Through CFD flow field simulation to optimize the layout of the pipe network, the pressure loss is controlled within 0.02MPa/100m, and the balance optimization of gas supply quality and operating cost is realized.

    Can I turn on the air compressor first and then the freeze dryer?

    Yes, it is theoretically possible to turn on the air compressor first and then the freeze dryer, but it is not the best operation sequence. In actual operation, although the air compressor provides the compressed air required by the freeze dryer, in order to ensure the normal operation of the equipment and the quality of the compressed air, it is more recommended.
