Abstract

The invention provides a carbon monoxide measurement system and measurement method for CDQ production, including a pressure sensor, a temperature sensor, a flow sensor, and a gas concentration sensor, wherein the pressure sensor, temperature sensor, flow sensor, and gas concentration sensor are respectively Connected to the controller, this scheme first obtains the measurable parameters in the CDQ production process as input variables, trains the MLP neural network model, and designs an adaptive NNG algorithm for the optimization of the MLP network structure, thereby eliminating redundant input variables , to achieve accurate soft measurement of carbon monoxide concentration.

Description

technical field [0001] The invention relates to the field of coke dry quenching production, in particular to a carbon monoxide concentration measuring system and method used in the coke dry quenching production process. Background technique [0002] In modern industrial production, in order to obtain more qualified high-quality products and improve economic benefits, it is necessary to strictly control product quality or important process variables closely related to product quality. Coke dry quenching (CDQ) is an advanced energy-saving technology widely used in the steel industry. The process flow chart of the CDQ system is as follows: figure 1 . The system is mainly composed of dry coke quenching tower, waste heat recovery boiler and turbine generator. During the production process, the CO concentration in the circulating air is critical to production efficiency and safety. Insufficient CO concentration will increase the combustion loss of coke, thereby reducing coke p...
