Utility model content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art, it is provided that can automatically detect and control the electric control system of a kind of desulfurization of each equipment normal operation in desulphurization system.
The electric control system of a kind of desulfurization, including the PLC being connected with detecting system and control system, described PLC receives the detection signal sent by detecting system and processes, and issuing instructions to control system；Described detecting system includes desulfuration absorbing tower sulfur dioxide concentration detector, circulatory pool pH detector, circulatory pool fluid level transmitter, calcium and magnesium slurry liquid basin fluid level transmitter, desulfurization regeneration knockout drum pH detector, absorption tower demisting device differential pressure pickup and pipe pressure sensor；Described control system includes clarified water pump, slurry feeding pump, reflux pump, regeneration pump, desulfuration recycle pump, calcium and magnesium dredge pump and demister.
Further, described fluid level transmitter is separately positioned on circulatory pool, calcium and magnesium slurry liquid basin and desulfurization regeneration knockout drum.
Operation principle of the present utility model is, the real time input data that PLC detects according to desulfuration absorbing tower sulfur dioxide concentration detector, circulatory pool PH detector and desulfurization regeneration knockout drum pH detector, carry out calculating and sending and go out instruction, correspondingly control clarified water pump, reflux pump, regeneration pump and the running of desulfuration recycle pump, to ensure that desulfuration efficiency is more than 90%, and discharge sulfur dioxide in flue gas concentration is less than environment protection emission index；By the detection data of the fluid level transmitter on circulatory pool, calcium and magnesium slurry liquid basin and desulfurization regeneration knockout drum are analyzed and send instruction, correspondingly control the level stability in circulatory pool, calcium and magnesium slurry liquid basin and desulfurization regeneration knockout drum；By the detection data of absorption tower demisting device differential pressure pickup and pipe pressure sensor are analyzed and send instruction, correspondingly control demister and be rinsed.
The beneficial effects of the utility model are:
(1) automatically adjusting the desulphurization circulating water yield and calcium and magnesium slurry liquid addition according to sulfur dioxide concentration and circulatory pool pH value in turnover desulfurization fume, to ensure that desulfuration efficiency is more than 90%, and discharge sulfur dioxide in flue gas concentration is less than environment protection emission index；
(2) level stability in calcium and magnesium slurry liquid basin, circulatory pool and regeneration separation integrated apparatus is automatically kept；
(3) according to the differential pressure recorded, desulfurizer mist eliminator is carried out auto-flushing, to keep demister properly functioning.
Accompanying drawing explanation
Fig. 1 is system structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, detailed description of the invention of the present utility model is described in further detail:
As it is shown in figure 1, the electric control system of a kind of desulfurization, including the PLC being connected with detecting system and control system, PLC receives the detection signal sent by detecting system and processes, and issuing instructions to control system；Detecting system includes desulfuration absorbing tower sulfur dioxide concentration detector, circulatory pool pH detector, fluid level transmitter, desulfurization regeneration knockout drum pH detector, absorption tower demisting device differential pressure pickup and pipe pressure sensor；Control system includes clarified water pump, slurry feeding pump, reflux pump, regeneration pump, desulfuration recycle pump, calcium and magnesium dredge pump and demister；Fluid level transmitter is separately positioned on circulatory pool, calcium and magnesium slurry liquid basin and desulfurization regeneration knockout drum.
The above is only preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; on the premise of without departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications should also be as being considered as within protection domain of the present utility model.
