The invention discloses an intelligent cooperative control method of multiple contaminants in
coal-fired industrial source
flue gas. The intelligent cooperative control method comprises the followingsteps: (1) enabling to-be-processed
flue gas to enter into an SCR (
Selective Catalytic Reduction) denitration
system to remove
NOx, wherein the denitration
system adopts a
honeycomb type catalyst, anda denitration
reducing agent is fully mixed with the
flue gas by adopting a spraying form; (2) enabling the gas processed in the step (1) to enter into an electric-bag integrated dust removal
system,and improving charged quantity of particles by adopting a critical pulse power technology to purify
smoke dust in the gas; (3) enabling the
flue gas processed in the step (2) to enter into a wet process desulfurization system, performing desulfurization by adopting an improved
lime / limestone-
gypsum process desulfurization absorbent; mixing the desulfurized absorbent sprayed and atomized by a
flue gas ejector with the
flue gas to carry out adsorption removal of heavy
metal mercury. According to the intelligent cooperative control method of the multiple contaminants in the
coal-fired industrial source flue gas disclosed by the invention, the removal efficiency of the multiple contaminants can be effectively improved, operation
energy consumption is reduced, and a
system error ratio is reduced; moreover, remote centralized operation, maintenance and fault diagnosis on the system can be achieved.
