Using said structure, by the setting of deflector so that the solution that sewage draining exit is discharged is introduced in detection water tank sets There is a side of PH sensor, and in the presence of new solution is sent into, at original solution flows to opening from the flow-guiding mouth of bottom Enter into discharge casing, it is to avoid the new solution entering directly overflowed in discharge casing by opening so that PH sensor detected value more Stick on the nearly pH value discharging solution itself, improve feedback effectss and feedback speed further.
It is further arranged to:Be provided with self-cleaning filter between the spraying mechanism of described water circulating pump and front portion, described from The slag-drip opening of cleaning filter is connected to the ground ditch.
Using said structure so that the solution being sent to spraying mechanism from cyclic water tank first passes through self-cleaning filter carries out Filter, reduce pollutant, the desulfurization that wet electrical dust precipitator is improved with this and the dust removing effects such as particulate matter of residual in solution.
It is further arranged to:Alkali liquor in described lye tank is the NaOH solution of 30-40% or Mg for concentration(OH)2 solution.
Using said structure, using the control of the dilution convenient consumption of aqueous slkali, reduce the waste of aqueous slkali.
It is further arranged to:Described flush box is sulfur removal technology water tank.
The fresh water (FW) being accomplished by itself in sulfur removal technology, therefore adopt said structure, flush box is set to desulfurization work Skill water tank can make full use of equipment, reduces the area occupied of equipment, improves the utilization rate of equipment.
It is further arranged to:Described sulfur removal technology water tank is connected with cyclic water tank, for cyclic water tank moisturizing.
Using said structure, by sulfur removal technology water tank to cyclic water tank first time moisturizing, simultaneously molten in cyclic water tank Can be supplemented when liquid is very few.
It is further arranged to:Described lye tank is connected on storage alkali tank, is provided with liquidometer in described lye tank.
Using said structure, by storing up the setting of alkali tank, lye tank is supplemented, when liquidometer detects alkali in lye tank When liquid is very few, alkali liquor in storage alkali tank is replenished in lye tank.
It is further arranged to:Described anterior spraying mechanism quantity is more than the spraying mechanism quantity at rear portion, described wet type electricity The air inlet end of cleaner unit is provided with airflow-distribution board, and in described anterior spraying mechanism, at least one is used for purgative gas flow point Fabric swatch.
Using said structure, by the spraying mechanism of enough front portions, flue gas is neutralized and removes most The grain pollutant such as thing, now, flue gas, to the corrosion of collecting electrode below and minimum, is rinsed by fresh water (FW), And only need few water, improve the utilization rate of water resource.
In sum, the invention has the advantages that:
1st, the aerosol of the formation such as efficient removal PM2.5 fine particle dust and SO3 and NH3, and realize water source circulation make With substantially reducing water consumption and solving the problems, such as buck secondary pollution;
2nd, the liquid of spray in wet electrical dust precipitator is allow to neutralize sour corrosion flue gas by adding alkali liquor, protection is internal Part, mitigates the effect of inner part corrosion;
