Smokeless coal-charging gas collecting pipe pressure intelligent control system

Abstract

The invention discloses a smokeless coal-charging gas collecting pipe pressure intelligent control system. The smokeless coal-charging gas collecting pipe pressure intelligent control system comprises an internal and external interface system, a data processing system, an intelligent computing center system, an execution system, a data collection center system, a central control system, a client end and a working condition signal processing module, wherein the internal and external interface system is electrically connected with the data center system in a bidirectional way; the data center system is electrically connected with the intelligent computing center system in a bidirectional way. The smokeless coal-charging gas collecting pipe pressure intelligent control system has the advantages that the defects of lack of feedforward analysis, data mining and coordinated control and higher energy consumption are overcome; the energy is saved, the consumption is decreased, the pressure of a gas collecting pipe is stabilized, the surge of a fan is treated, the pollution to environment is reduced, the chemical production efficiency is improved, the production cost of enterprises is reduced, and the requirement of environment change is met; the accuracy is good, the stability is high, the applicability is strong, and the subsequent maintenance and upgrading is convenient.

Description

technical field [0001] The invention relates to the technical field of smokeless coal charging gas collection pipes, in particular to an intelligent pressure control system for smokeless coal charging gas collecting pipes. Background technique [0002] In the coking process, the pressure of the air collecting pipe, the suction force before the primary cooler, and the speed of the blower are very important technological indicators. The existing control on the pressure of the gas collecting pipe, the front suction of the primary cooler, and the speed of the blower still stays in the traditional process control, with a lag in adjustment and a lack of feed-forward analysis; secondly, each control loop is relatively independent, and lacks coordinated control based on the various links of the entire process. The initial values ​​of each control cannot be automatically corrected according to the coking working conditions, there is no analysis and mining of data, the lack of discove...

Problems solved by technology

The existing control on the pressure of the gas collecting pipe, the front suction of the primary cooler, and the speed of the blower still stays in the traditional process control, with a lag in adjustment and a lack of feed-forward analysis; secondly, each control loop is relatively independent, and lacks coordinated control based on the various links of the entire process. The initial values ​​of each control cannot be automatically corrected according to the coking working conditions, there is no analysis and mining of data, the lack of discovery of production rules, and no expert control rules for the analysis of the causes of equipment states such as excessive adjustment of disc valves and excessive fan loads; When factors such as coke pushing, coal loading, reversing, and pressure changes after the fan are affected, the pressure of the gas collecting pipe will fluctuate frequently and greatly, and the power consumption of the primary cooler and the blower will be large. Serious impact on the service life of the furnace and environmental protection
