Monitoring method for energy-saving emission reduction real-time quantization of dry method cement product line

Abstract

The invention relates to a real-time and quantitative method for monitoring the energy-saving and emission-reduction of a production line for cement produced by the dry method, belonging to the field of energy-saving and monitoring methods. The monitoring method is as follows: high-temperature gas analytic devices with the function of mobile phone communication are respectively installed on the outlets of a tail smoke chamber of a rotary kiln and a decomposing furnace, and are used for the continuous on-line measurement and analysis of the component content of high-temperature waste gas; a medium temperature gas analysis meter is installed on the outlet of a preheater, and is used for the measurement and the analysis of the component content of the waste gas of the preheater; a powder measuring apparatus is installed on the outlet of a chimney, and is used for the measurement of the content of powder discharged from the chimney of a production line; and the high-temperature gas analytic devices, the gas analysis meter and the powder measuring meter are respectively in transmission connection with a computer by single mode fibers, and the computer and an intelligent mobile phone form wireless communication by a mobile phone communication module so as to transmit displayed pictures of the computer. The method adopts the computer as a monitoring reservoir, information is transmitted into the mobile phone by wireless telecommunication transmission, and the method has the advantages of easy monitoring and easy execution.

Description

technical field [0001] The invention relates to an energy-saving monitoring method, in particular to a real-time quantitative monitoring method for energy-saving and emission-reduction of a dry-process cement production line. Background technique [0002] At present, my country's cement industry has always used extensive calculation methods for energy consumption evaluation, mainly based on the "thermal calibration" data when the production line is completed and put into production; or the accounting method of calculating the general ledger every month and every year; How much clinker is used, how much coal is used, how much coal is used per kilogram of clinker, and then multiplied by the average calorific value of coal per kilogram to obtain the heat consumption value per kilogram of clinker. Energy consumption and pollution emissions in the cement industry, especially coal consumption, are mainly concentrated in rotary kilns and calciners. Due to the large production capac...
