What are the energy-saving transformation schemes for compressed air system?

1. Compressed air is converted from mechanical energy of air compressor. Different air compressors need to optimize the operation mode, reasonable configuration and maintenance. To ensure the degree of energy saving, three conditions need to be completed to ensure the air cleanliness of the air inlet; Reduce the inlet temperature of air compressor and improve efficiency; Choose an oil-free air compressor;

2. Dryers and precision filters belong to compressed air purification equipment, so when choosing dryers, attention should be paid to choosing the latest mold core dryer, which has the advantages of high adsorption efficiency, low energy consumption, low regeneration gas consumption, long service life and convenient maintenance. Precision filters are installed at the front and back ends of the dryer according to the principle of "three front and one front" to ensure the quality of compressed air at the gas end.

3. Compressed air transportation

1) pipe network configuration optimization, separation of high and low pressure gas supply pipelines;

A: Change the pipeline with branch layout into loop layout, and install high and low pressure precision overflow devices; B: Replace the pipeline with large local resistance to reduce the pipeline resistance; C: Clean the inner wall of the pipeline by pickling, derusting and other methods. So as to ensure smooth pipe wall.

2) leakage, blockage, leakage and blockage

A: install the flow measurement management system of the gas supply pipeline in the main production workshop and determine the process dose limit; B: Adjust process gas consumption, reduce the number of valves and joints as much as possible, and reduce leakage points; C: Strengthen management and regularly use professional tools to find bolts.

4, the use of compressed air

In order to save energy, it is necessary to improve the cylinder drive circuit first, and use energy-saving products developed for this industry, such as special throttle valve for cracking cylinder in aluminum industry, energy-saving air gun and nozzle.

5. Recover the residual heat of the air compressor.

The usual method to recover the waste heat of air compressor is heat exchange, so that the recovered waste heat can be reused and can be used for auxiliary heating and process heating.
