"Lanzhou Petrochemical Company's power plant is not only an energy supply unit for water, electricity, gas, and wind, but also a large energy user. Protecting supply while reducing energy consumption is our top priority."
Technical staff Wang Hao introduced: “In 2011, we achieved a monthly reduction in energy consumption on the basis of exceeding our mission.â€
Section steam optimization program, strengthen inspection. According to the second-level energy consumption index of 2011, the plant has decomposed the total energy consumption of each device. They continuously optimize the steam supply program, adjust the steam supply lines of the steam system according to the steam consumption of different units, and meet the production requirements, so as to minimize the supply of steam. At the same time, they reduced the amount of steam supplied by the external steam supply units by increasing the amount of self-produced steam, and strengthened the detection of boiler thermal efficiency and the “three doors and one board†adjustment. The boiler combustion parameters were adjusted in time according to changes in the boiler load. Equipped with a single thermal efficiency detector, the thermal efficiency value of the boiler can be monitored in time to maximize the thermal efficiency.
At the same time, the plant implements meticulous management, and the employees strictly follow the production operation procedures and process requirements with meticulous and meticulous operation, earnestly control the degree of switching of the valve and reduce the consumption of circulating water; and strengthen the inspection of the steam system, once the leakage point is found. Immediately issue plug-in notices to the responsible units to supervise and assist the responsible units to plug leaks as soon as possible.
Water conservation depends on the source and stable operation. We will carry out research on the quality of circulating water, strengthen the monitoring of the quality of circulating water, and insist on finding problems in the early stages of water quality anomalies. Dealing with these problems in time at the source is an important measure for power plants to save water. During the treatment of circulating water, the plant continuously optimizes the water treatment process, ensuring the long-term stable operation of the reverse osmosis concentrated water reuse device, backwash wastewater reuse device, and steam condensate deoiling and iron removal device, thereby reducing the The external discharge of circulating water increases the utilization of recycled water. In addition, the use of treated production wastewater and domestic sewage to replace fresh water, as well as the reuse of recycled water, is also an important water-saving measure of the plant.
Saving electricity depends on careful maintenance and reasonable adjustment. The plant strengthens the daily maintenance of equipment and equipment, eliminates the unplanned start-up and shutdown phenomenon, and timely adjusts the current of the unit according to the production demand, so as to ensure that the motor group is always in a low-load operation state, thereby reducing the power consumption. They also optimize the conditions of each device through frequency conversion facilities according to the energy requirements of specific devices, so that all power equipment facilities are in the best operating state, thereby reducing the power consumption of electrical equipment.
For wind and nitrogen systems, the plant adjusts the dryer and air tank usage on an hourly basis to reduce the internal resistance of the dryer and the air tank, allowing the compressor to achieve optimal operation. At the same time, they routinely clean the inlet filter of the air system to ensure that the unit is in a low-load operation state; reasonably control the boiler load, control the amount of air distribution and the amount of smoke exhausted, reduce the operation load of the fan, and then reduce the power consumption of the fan.
In addition, the factory also ensures the stable supply of energy through small reforms of small leather and various forms of activities to reduce the energy consumption of each device and achieve the dual goals of energy supply and energy conservation .
