Modularized control system for large desulfurization equipment

Abstract

The invention discloses a modularized control system for large desulfurization equipment, and belongs to the technical field of environmental protection control. The control system is applicable to a wet-process flue gas desulfurization system. The modularized control system for large desulfurization equipment is divided into four main parts, namely, a desulfurization process control module, a process monitoring module, a flue gas detection module and an upper computer control module, according to the characteristics of desulfurization device and the principle of configuration; the desulfurization process control module is used for controlling an induced draft fan, an oxidation compressor, a lime milk pump, a slurry circulation pump and the like; the process monitoring module is used for monitoring an analogue quantity detection module, a switch quantity detection module and a site video equivalent; the flue gas detection module is used for measuring sulfur dioxide, nitric oxide, temperature and pressure equivalent; and the upper computer control module is used for controlling a lower computer by a server, an industrial personal computer and the like. The modularized control system for large desulfurization equipment disclosed by the invention is beneficial to research and development for an electric control device for large desulfurization equipment, thus achieving management for sulfur dioxide and protecting environment.

Description

technical field [0001] The invention relates to the technical field of control of large-scale desulfurization devices, in particular to the control of large-scale wet desulfurization devices, and belongs to the technical field of environmental protection. Background technique [0002] Our government attaches great importance to SO 2 The control job, the control SO 2 emissions is the focus of environmental protection. At present, flue gas desulfurization includes dry method, semi-dry method and wet method, among which wet method accounts for more than 95% of desulfurization devices. my country's desulfurization control devices are generally entered together with the desulfurization device. The installed monitoring system is divided into two types according to the function: one is supporting the desulfurization and dust removal equipment; the other is the pollution source monitoring. According to statistics, the application situation of environmental monitoring systems is ...

Problems solved by technology

The main reason for this situation is that the desulfurization control system has not been modularized, resulting in major problems in the after-sales service of the product, which will inevitably lead to low desulfurization efficiency and waste of resources, resulting in an increase in desulfurization costs
