1 Overall energy-saving control technology (1) Large-capacity side-mounted capacitor compensation system, local compensation, improved power factor and reduced line loss. Automatic compensation is used to ensure proper compensation. (2) Organize production with low electricity price period and reduce production costs. (3) Scientifically arrange production schedules, coordinate and cooperate between different shifts, so that the batch production volume of each production will reach the minimum economic production scale, reduce frequent replacement of varieties and lead to downtime, no-load time, and improve energy utilization. effectiveness. (4) Close the unneeded equipment in time to avoid the equipment idling. 2 Energy-saving technology for boilers and steam systems In order to get the most efficient operation with the lowest energy consumption, the boiler and steam system must be in the best operation. This includes the : (1) The water is properly softened and chemically treated to prevent scaling and corrosion of the water in the boiler. The correct chemical treatment is used to control the pH of the total soluble solids and water in the steam. Use the correct drain program to remove solids and impurities from the bottom of the boiler to avoid excessive blowdown. (2) Correctly adjust the burner's air-fuel ratio to achieve clean combustion. (3) Take the following measures to minimize energy consumption or loss in production steam: a. Do not operate the boiler at a higher pressure than required for processing operations. b. Turn off the system when steam is not needed. c. Check whether the boiler water is properly chemically treated as usual and adjust according to the situation. d. Regularly discharge sewage, but do not do excessive sewage operations. e. Regularly check whether there is steam leakage, whether the steam separator, trap, and pressure reducing valve work normally, and whether the valve is faulty. 3 compressed air system More than 80% of the cost of compressed air is the cost of electricity. A properly operating compressed air system is very important for saving electricity. Therefore, improving the efficiency of the system has a great impact on reducing operating costs. (1) Excessive use of electricity in compressed air systems, the most common reasons are: operating at higher pressures than required, leakage and air inlet resistance. For example, a leak with a diameter of 3.175mm will leak 251,454M3 of air a year at a working pressure of 0.7 MPa, which is equivalent to about 24,000 kWh of electricity. At a cost of 0.6 yuan / kWh, the annual loss will be 14,400 yuan. Most air compressors have a displacement of 0.147~0.187 M3 /min per kilowatt at a discharge pressure of 0.7MPa. The increase or decrease of pressure by 0.014MPa will affect the energy utilization of the compressor by 1%, and the inlet air temperature will vary by 10°C. Will affect the compressor efficiency by 1%. The pressure drop across all parts of the system and the pump should not exceed 0.1 MPa. (2) The following measures should be taken to minimize the energy consumption or loss in the compressed air system: a. Do not operate the system above the pressure required. b. Regularly turn off all gas equipment and check for air loss. c. Regularly drain the gas storage tank and riser. d. Keep the inlet air clean and filtered.
