Embodiment Construction

[0041] The present invention is described in detail below in conjunction with the specific embodiments of the accompanying drawings.

[0042] The invention is based on the diagnosis and analysis of all parameters related to the energy efficiency of the equipment. For clarity, the parameters are divided into three categories, namely production parameters, energy efficiency parameters, and operating parameters. For a given device, these three types of parameters can be used to comprehensively and definitely describe the energy consumption status of various equipment in the process industry, that is, each energy consumption status data includes three sets of data including production parameters, energy efficiency parameters and operating parameters. Production parameters include production load, energy characteristics, raw material types, product grades and quantities, etc., which determine the level of energy efficiency parameters. Energy efficiency parameters are indicators to ...

Abstract

Process industrial equipment serves as an analysis and diagnosis object, and an energy utilization state of the process industrial equipment is described through production parameters, energy efficiency parameters and operating parameters of the equipment. The method comprises the following steps of: in the process of operating the equipment, acquiring production process data of the equipment anddetermining the optimal energy utilization state; establishing an energy utilization state diagnosis tree according to expert knowledge, and comparing a real-time energy efficiency parameter with theoptimal energy efficiency parameter; triggering diagnosis if a real-time energy utilization state of the equipment is lower than the optimal energy utilization state, reasoning according to the energy utilization state diagnosis tree, and giving reasons and recommended measures after the reasoning is finished. By the method, the energy utilization state of the equipment using fuel, power, heat and other energy in various process industries can be monitored and diagnosed, and the method has universality.

Description

technical field [0001] The invention relates to the field of process industry energy management and optimization, in particular to a method for diagnosing the energy state of process industry equipment. Background technique [0002] The energy consumption state of equipment refers to the energy utilization status within the boundary of a type of equipment that uses fuel, electricity, heat and other energy sources in the process industry during its operation. The status of energy utilization is often characterized by energy efficiency, that is, the ratio of the effective energy used by the equipment to the total energy input by the equipment. Energy efficiency is related to the characteristics of the equipment itself, operating conditions and operation, and is the result of a combination of factors. For a given device in the production process, it is very meaningful to diagnose the problems existing in its energy use and find ways to improve energy efficiency from the variou...
