Plant Energy Conservation Engineering System Design

With the popularity of the concept of energy conservation and emission reduction, many enterprises have paid much closer attention to the planning, design and management of the energy conservation project in the factory. However, the energy saving in the factory is a complicated system engineering, which involves a varity of fields. At present, there isn't a perfect planning or design in energy saving engineering in the factory system.In this paper, it is firstly analyzed the factory main power consumption system: the equipment structure and working principles of the distribution of power system, lighting system and the power supply system, etc. And it is analyzed and calculated on equipment energy consumption in detail. Based on this analysis, the design principles and reconstruction scheme about energy saving has been proposed.For intanse, it can be applied to the update of high loss transformer in power supply system, at the same time, it is studied on traditional equipment defect and provided calculation methods for replacement and design solution for using solar device instead of fuel boilers of hot water supply, etc.The method in the topic has get proved and applied in 3M factory.Through the implementation of the project above, the results of the energy conservation project operated in power supply system in the factory show that: it would save more than 1.55 million KWH annually, which equals the energy saving cost of 1.05 million RMB every year. Thanks to this reconstruction project, the XXX factory got the prize of "important energy-saving project", and received specific energy-saving subsidies from governemnt.It finally concludes the scientific management method about energy saving in the factory system, which is based on the system energy-saving technical renovation scheme. There will be a good example for renovation plan and management plan in the system energy-saving technology to energy conservation reform in the factory.
