Analysis of the principle of "pneumatic energy saving" in air compressor system

Basic principle: reducing air consumption is saving energy

In the industrial field, compressed air is one of the most common energy sources used in the production process, and air compressors are like refrigerators everywhere in the house. The difference between it and the refrigerator is that the former is "pneumatic" and the latter is "electric." For pneumatic systems, reducing air consumption means saving energy.

At present, the energy utilization of compressed air systems in my country’s manufacturing enterprises is not optimistic. Although the air compressor equipment is good, the matching rate of supply and demand is low. In gas-using enterprises, there are widespread unreasonable terminal equipment and leaks. , Lack of measurement and other issues, serious waste of gas consumption in the production process. In addition, the factory’s actual demand for “gas” has seasonal and temporal fluctuations, and its gas consumption fluctuates greatly; at the same time, the frequent loading and unloading process caused by the air compressor not operating at full load most of the time will also greatly waste gas. Electricity.

It can be seen from this that the direct energy-saving method for enterprise z* is to raise the awareness of "gas cost" and attach importance to the universal truth of "management yields benefits".

Core principle: to realize the overall management "from the source to the end"

Energy saving of air compression system mainly includes two aspects:

On the one hand, "energy saving" management must be carried out on the source air compressor station. "Energy saving" simply means to improve the operating efficiency of the air compressor and increase the air matching rate. Through predictive control, fault-tolerant control, self-learning algorithm, cloud computing data processing and other technical means to control the air compressor group, the gas production after optimizing the operation can match the gas consumption of the industrial site.

On the other hand, "refined" management of the terminal. Reducing end-end demand is directly reducing the amount of consumption, reducing energy consumption from the source of use. Therefore, how to improve the management level of the system and improve the utilization efficiency of the terminal and related equipment of the pipe network are the main issues to be considered for energy conservation in this link.

In the entire energy-saving process, the energy-saving space at the "source" accounts for 10%, while the "end" energy-saving space is as high as 30%. Therefore, energy conservation requires overall management.

According to reports, this method is an energy-saving patent of Aishe Technology, which is currently the only company in China that has carried out energy-saving transformation of the "compressed air system". It also pioneered the energy-saving idea of ​​"from the source to the end". This overall energy-saving solution has been verified by more than 30 well-known companies. In addition, it has a special service called "personalized energy-saving diagnosis service." In energy-saving diagnosis, "setting the compressor loading and unloading priority" is a very important link. It makes an overall judgment of the air compressor system "from the source to the end", determines the "energy-saving rate", and saves energy in the later period. After the project is implemented, the energy-saving goal will be achieved. The company's energy-saving investment will be fully rewarded within a period of about 9-15 months! Such an efficient energy-saving solution is worth trying.
