Coking gas desulfurization and denitrification integrated equipment centralized management and control system

Abstract

The invention relates to a coking gas desulfurization and denitrification integrated equipment centralized management and control system, which comprises a coking production section and desulfurization and denitrification integrated engineering section DCS (Distributed Control System) and a data processing unit, wherein the data processing unit is connected with the coking production section and desulfurization and denitrification integrated engineering section DCS, and thus, coking production process data and gas desulfurization and denitrification integrated process production data, energy data and operation parameters are acquired through the coking production section and desulfurization and denitrification integrated engineering section DCS, and the air pollutant emission concentration and the desulfurization and denitrification efficiency can be calculated in real time. The embodiment of the invention organically integrates the coking production part and the desulfurization and denitrification part to a complete industrial process loop, interconnection and intercommunication of data of the coking production part and the desulfurization and denitrification part are realized, the relationship between the coking production section and the esulfurization and denitrification integrated section is mined thoroughly, and through interconnection and intercommunication of the data, informationization of the data of the coking enterprise desulfurization and denitrification integrated equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of industrial flue gas treatment information management and control systems, in particular to a centralized management and control system for coking flue gas desulfurization and destocking integrated equipment. Background technique [0002] my country is the largest coking producer in the world. The "Emission Standards of Coking Chemical Pollutants" officially implemented on January 1, 2015 put forward strict and clear quantitative requirements for the emission indicators of sulfur dioxide and nitrogen oxides in the coking chemical industry. A coking plant is the first in China to adopt the integrated process device of wet ammonia forced turbulent desulfurization and forced oxidized urea denitrification, which is an important means to treat coking industrial flue gas. The equipment included in the existing desulfurization and denitrification integrated device includes induced draft fan, waste heat recovery b...

AI Technical Summary

Problems solved by technology

[0006] The existing device has the following problems: 1. It only relies on the DCS system of the desulfurization and denitrification integrated equipment for control, and the function is simple; 2. There are few data sources in the desulfurization and denitrification section, and the data only includes the desulfurization and denitrification section. Fusion analysis is not conducive to process modeling, optimization and control
