How much do you know about energy-saving upgrades for air compressors? How can air compressors be made more energy-efficient?
Thread Content
Compressors are key energy-consuming devices in enterprises and possess energy-saving potential. Among the operating costs, the purchase cost accounts for only 5%, maintenance costs make up 18%, while electricity costs account for 77%. Implementing energy-saving measures for compressors will significantly reduce these operating costs.
I. Group control energy-saving solution: Based on the group control of compressors, a user-friendly management approach is adopted, enabling maximum efficiency through real-time evaluation and coordinated operation. 1. Overall architecture of the swarm control system
2. Implementation steps of the group control system: a. Install cloud terminals to monitor parameters such as operation status and energy efficiency； Provides data for power savings and power savings rate estimation. b. Establish a management network system to provide comprehensive oversight of gas supply, equipment, energy consumption, maintenance plans, and more. c. Establish a logging system and maintenance plan to reduce failure rates and ensure a stable supply of compressed air. d. On the basis of this system, a comprehensive enterprise monitoring system (or energy monitoring system) can be further developed.
II. Replace with energy-efficient compressors: Screw compressors are widely used, but they have a low energy efficiency; the effective power for compressing air accounts for only 20% of the electrical power output. Therefore, improving one’s own efficiency and achieving energy-saving compressors will yield significant benefits.
III. Energy savings through optimization of gas transmission pipelines and endpoints – Optimizing the use of gas in pipelines and endpoints can lead to significant energy savings for the system. This chapter explains common pipeline problems and provides a brief introduction to the solutions. Insufficient gas tank capacity: In practical applications, it is common for the gas storage capacity to be inadequate, leading to repeated loading and unloading and thus energy waste. By enlarging the air storage tank and allowing a single unloading process to last for a certain period of time, the power consumption during unloading can be reduced.
IV. Energy savings in compressors with attached dryers: In the chemical industry, high standards are required regarding the moisture content of compressed air; the use of cold dryers or adsorption dryers to dry the compressed air results in additional energy consumption. Interconnection with cold dryers: Cold dryers are usually operated in a rather crude manner throughout the year; by evaluating the humidity of compressed air (dew point) and interconnecting them, better energy savings can be achieved. Optimization of desiccators: Generally, adsorption dryers have two types of energy consumption: a) the energy used to compress air ； b、Electric power consumption for regenerative heating ； Dryers have high levels of energy consumption; through optimization, gas and electricity usage can be reduced, thereby eliminating unnecessary losses.
