Air compressor is a kind of equipment used to compress gas. The structure of air compressor is similar to that of water pump. Most air compressors are reciprocating plug type, rotating blade or rotating screw. Centrifugal compressor is a very large application. In order to realize the energy-saving effect of air compressor, the following 8 aspects should be paid attention to.
1. Control leakage
It is estimated that a 1mm? Under the pressure of 7bar, the leakage volume of the small hole is about 1.5l/s. Check all the transmission pipe networks and gas consumption points, especially the joints and valves, and deal with the leakage points in time.
2. Pressure drop control
Set up a pressure gauge to detect the pressure through the pipeline section, check the pressure drop of each section in detail, and check and maintain the problematic pipe network section in time. Generally, the pressure drop from the outlet of Dongguan air compressor to the gas consumption point shall not exceed 1bar. Strictly speaking, it shall not exceed 10%, i.e. 0.7bar. The pressure drop in the cold and dry filtration section is generally 0.2bar The plant shall try to arrange annular pipe network to balance the gas pressure at each point.
3. Adjust the pressure matching of gas equipment
Evaluate the pressure demand of gas equipment, and try to reduce the exhaust pressure of Huizhou air compressor while ensuring production. When the exhaust pressure of Dongguan air compressor decreases by 1bar, energy saving is about 7~10%.
4. Adjust unreasonable gas consumption behavior
According to authoritative data, the utilization rate of electric energy of Huizhou air compressor is only about 10%, and about 90% of it has been converted into heat energy loss. It is necessary to evaluate the plant pneumatic equipment and whether it can be solved by electric means. Meanwhile, the use of compressed air for routine cleaning shall also be resolutely prohibited.
5. Adopt centralized control mode
The number of secondary compression air compressors is small, so one variable-frequency air compressor can be used for pressure regulation. If the number is large, centralized linkage control can be used to avoid the step exhaust pressure rise caused by the parameter setting of multiple air compressors.
6. Maintain and clean the equipment
Increase the heat dissipation effect of Dongguan air compressor and the exchange effect of water cooling, air cooling and other heat exchangers to keep the oil clean.
7. Huizhou air compressor waste heat recovery
The oil of secondary compressed air compressor is recycled to prepare hot water for other processes or auxiliary living facilities.
8. Modification or replacement of drying system
The new drying equipment uses the waste heat of compressed air to dry and dehydrate the compressed air, and the energy saving rate is more than 80%.
