Integrated management system of energy information of cement enterprises

Abstract

The invention relates to an integrated management system of energy information of cement enterprises. The system comprises a coal, electricity and water data collection network, an energy management server, an energy optimization server and an energy data distribution intranet. The coal, electricity and water data collection network is connected with a DCS (distributed control system) through a fiber transceiver and is used for collecting and transmitting cola, electricity and water data. The energy management server is in data interconnection with the DCS through industrial Ethernet and is used for acquiring various energy related data and managing the data. The energy optimization server reads the related energy data in a DCS OPC server through an OPC client, performs optimal computing, and writes results into the DCS through the OPC client, thereby optimizing energy in the production process. The four components are organically integrated through an Ethernet interface module and the OPC server provided in the original cement enterprise DCS, the integrated management system has the advantages such as ease of integration and low cost, and energy data of cement enterprises can be acquired, stored, analyzed and managed.

Description

technical field [0001] The invention relates to the field of energy management in the cement production process, in particular to an energy information collection network for cement enterprises, and energy optimization scheduling and management in the cement production process. Background technique [0002] The production of new dry process cement usually takes "one kiln and three mills" as the main body to form different process areas. At the same time, there are corresponding raw materials, intermediate material storage and transportation equipment, such as figure 1 shown. The whole production process needs to consume a large amount of coal as fuel to complete clinker calcination, and consume a large amount of electric energy to drive large-scale grinding equipment to complete the grinding of raw materials, coal and cement products. The energy consumption of clinker production accounts for about 10% of the total energy consumption of cement production 70% to 80% of the el...

AI Technical Summary

Problems solved by technology

[0004] (1) Lack of collection and management of electricity and water energy medium consumption data

The company's existing electric power meter has low accuracy, and there is a calculation from electric power to electric energy, which has a huge error; water meters generally use old-fashioned pointer water meters, which have low accuracy and require manual meter reading

The monitoring equipment for electric energy and water is outdated, and it is impossible to realize the online collection and management of electricity and water energy medium consumption data

[0005] (2) The energy information of each production workshop of cement enterprises is independent, and there is a lack of sharing of energy information among production workshops

[0006] (3) Lack of optimal scheduling of energy in the cement production process

Due to the independent accounting of each production workshop, the current production management system aims at the lowest energy consumption of each production unit. Raw meal mills and coal mills often start and stop frequently due to overproduction, resulting in a large amount of energy waste
