Embodiment Construction

[0150] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0151] The system of the present invention is used to optimize the operation of the energy system of a papermaking enterprise in a cogeneration mode. The energy conversion link of the enterprise includes 4 fluidized bed boilers, 4 extraction condensing turbines and a number of temperature and pressure reduction equipment. thermal system. The working method is as follows:

[0152] first step, such as image 3 , 5 As shown, the energy consumption related data of each department is collected from the SCADA, PLC, DCS and data collectors in the pulp and paper production line, thermal power workshop, water treatment workshop, office dormitory, canteen and other production and living assistance workshops. The obtained data is stored in the real-time database for calling by t...

Abstract

The invention discloses a paper mill cogeneration energy system optimization system and a working method thereof. The system comprises a data collection system, a real-time database, a relational database, a material flow simulation model library, an energy flow simulation model library, an energy flow optimization model library and a human-computer interaction interface which are mutually connected; the system collects key data of energy consumption through the data collection system and stores the key data into the relational database; the material flow simulation model library, the energy flow simulation model library and the energy flow optimization model library calls the data in the relational database for optimization; the optimization result is stored in the relational database; the optimization of an automatic proceed system is called by a field controlling system, such as SCADA, DCS and the like. The system in the invention can realize economic operation of cogeneration energy system, effectively save energy sources, and reduces operation cost or improves profits.

Description

technical field [0001] The present invention relates to an optimization system of cogeneration energy system of a pulp and paper mill and its working method, in particular to the cogeneration energy system of large and medium-sized pulp and paper mills with more than or equal to two boilers or two sets of steam turbine generator sets Optimizing the system and how it works. Background technique [0002] The paper industry is a resource and energy-consuming industry. With the rapid development of my country's national economy, the consumption of paper products is increasing rapidly, and the market demand is expanding year by year. The paper industry has been listed by the National Development and Reform Commission as one of the nine high-energy-consuming key regulatory industries. The combined heat and power system is an important part of the pulp and paper making enterprise, and its safe and stable operation is the basis for the safe, stable and long-term operation of the en...
