How to save energy and reduce emissions for air compressors? Super pipeline manufacturers to support

Today, with the development of automation, compressed air is widely used in all aspects of the industrial field due to its unique advantages of cleaning, safety and convenient application. It has become the second largest power source worthy of the name. Almost all manufacturing factories use this power source more or less. As the main equipment for producing compressed air, various types of air compressors are applied to various factories, consuming a large amount of energy

Brief introduction of energy saving significance of air compressor

After nearly two decades of rapid economic growth, China has become the center of the global manufacturing industry. The large-scale increase in output has caused huge resource consumption and energy demand. The rapid development is gradually restricting the further improvement of the national economic strength. Therefore, the decision of the State Council on strengthening energy conservation in 2005 clearly States:

By the end of the 11th Five Year Plan (2010), the energy consumption per 10000 yuan of GDP will be reduced by about 20% compared with the end of the 10th five year plan, and the average annual energy saving rate will be 4.4%.

The energy consumption per unit of major products in key industries has generally reached or approached the international advanced level at the beginning of this century.

The air compressor room needs to consume a large amount of power, so it can also be improved. According to the professional evaluation, the air compressor and related equipment can be transformed to save energy, reduce the operating cost, and improve the production efficiency and product competitiveness at the same time.

As a major energy consumer in the manufacturing industry, the air compressor has received more and more attention and has great energy saving potential.

*The average energy consumption of air compressors in industrial and mining enterprises accounts for about 30% of the whole enterprise

*The power consumption of air compressors in some industries accounts for 70% of the total power consumption

From the analysis of the investment cost structure, the energy saving focus of the air compressor is energy consumption. For the motor-driven compressor, the energy consumption can be approximately equal to the power consumption

Heat recovery of air compressor

For an electrically driven air compressor, it can be regarded as an electric heater approximately. During the process of compressing air, almost all electric energy will be converted into thermal energy, and the generation of these thermal energy will affect the normal operation of the air compressor. Therefore, in order to ensure the normal operation of the air compressor, a good cooling system must be installed for the air compressor to ensure the normal and safe operation of the air compressor. Not only is this heat not being used, but it also needs to consume additional energy to help cool. It can be described as follows: the real main product of the air compressor is heat, and the by-product is compressed air. However, in general applications, only its by-product is used.

Therefore, the heat recovery of the air compressor will greatly improve the comprehensive utilization of energy and realize the heat / gas CO generation.

The frequency conversion transformation of air compressors. At present, many air compressors are in operation, and a large part of the time is carried out under the condition of non full load. Energy loss is generated through the traditional standard control, thus causing a waste of power resources. The motor power of the power frequency air compressor is generally large, and the starting mode is no-load (unloading) star triangle startup. The loading and unloading modes are instantaneous, so that the air compressor will have a large starting current during startup, and a large amount of power will be wasted during loading and unloading.

The selection and allocation of air compressor must meet the gas consumption of the factory, but the actual gas consumption is small and variable. In view of this phenomenon, the transformation of frequency conversion control system is urgent
