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.
