Against the backdrop of global energy shortages and increasing environmental pollution, energy conservation and emission reduction have become crucial tasks across various industries. In the realm of mining machinery equipment, JUGONG air compressors play a significant role but are also major energy consumers. How to reduce the energy consumption of air compressors and enhance their operational efficiency has become a hot topic within the industry. The emergence of waste heat recovery technology for air compressors presents a new solution for energy conservation and emission reduction.
Waste heat recovery equipment for air compressors is particularly suitable for oil-injected screw air compressors. Implementing thermal projects for air compressors can provide hot water for enterprise domestic and production use, boiler water replenishment, low-temperature drying, and more. The highest energy utilization efficiency is achieved when using hot water in consumable ways, such as for employee showers, boiler water replenishment, and consumable hot water rinsing, showcasing its superiority. Implementing waste heat recovery projects for air compressors involves the following two points:
1. Selecting Suitable Waste Heat Recovery Equipment for Air Compressors
The heat generated during the operation of oil-injected screw air compressors can be effectively utilized, a fact recognized by many enterprises. Consequently, waste heat recovery equipment for air compressors has seen rapid development. What kind of equipment is most suitable? We believe that ensuring the safe operation of air compressors, sufficient utilization of waste heat, and having technical support with timely after-sales service define good equipment. The key lies in the safe operation and rational utilization of the equipment.
Excessive pursuit of hot water production capacity may lead to the air compressor being excessively cooled, resulting in excessively low oil temperature and the generation of condensation water, posing potential risks to the air compressor. Conversely, excessive temperature pursuit may lead to insufficient hot water production capacity and inadequate heat dissipation for the air compressor, reducing its lifespan and increasing the energy consumption of the main motor. Therefore, if an enterprise excessively emphasizes hot water utilization or focuses excessively on the temperature of the produced hot water, it may not necessarily be a wise decision. We understand that the primary function of an air compressor is to produce high-pressure gas, not to produce hot water. The purpose of utilizing heat energy is to achieve energy-efficient operation of the equipment, rational energy utilization, all while ensuring normal enterprise production and equipment safety.
2. Understanding Demand and Equipment Information
Firstly, understanding the enterprise's equipment and operational situation allows for a preliminary grasp of the amount of heat energy that the enterprise can utilize. This includes the number of water users in the enterprise, water usage methods, or the quantity of production water used. Understanding the enterprise's hot water consumption allows for the calculation of the enterprise's heat energy demand.
Secondly, understanding the enterprise's air compressor equipment situation involves conducting an energy audit of relevant equipment to comprehend their operational and energy consumption status. The main information to be understood includes:
A) Original heating methods and costs;
B) Air compressor operating time, primarily loading time;
C) Flow rate of air compressor circulating oil;
D) Site suitability for project implementation;
E) End distance;
F) Daily hot water usage;
G) Layout of air compressors and water storage, height differences, distance, orientation, equipment quantity, equipment power, operating time, operating temperature, etc.
