Ensure that the PH in absorption tower, a stationary value, needs to cover CaCO3Or the desulfurizing agent such as CaO or NaOH or MgO.
At present, dry desulfurizer feeding system (such as agstone, 250 mesh, 90% sieving rate), by self-tipping type hermetically sealed can
Car is transported to plant area, is transported to limestone powder bin.The agstone being stored in limestone powder bin is under the fluidisation of gasification blower fan, logical
Cross rotatory feeder valve and enter gypsum slurries case, blender powder and fresh water (FW) stirred and be sufficiently mixed, make concentration about 15～
The gypsum slurries of 30%, gypsum slurries serosity is pumped to absorption tower and carries out desulphurization reaction.Every absorption tower is furnished with a Calx
Alkalium liquid conveying endless tube, is recycled back into Calx alkalium slurry tank, and lime stone slurry is transported to by the lateral on endless tube
Absorption tower, to prevent serosity from precipitating blocking in conveyance conduit.In former wet method fume desulfurizing system, dry desulfurizer needs
First to carry out hybrid process with fresh water (FW) and to become serosity, and need special conveyer device that serosity is delivered into absorption tower.This
Sample, whole system needs to configure desulfurizer slurry case, agitator, delivery pump, water system with slurry, serosity pipeline system and instrument
The equipment such as table.Therefore, former wet method fume desulfurizing system structure is complicated, cost is higher.Owing to systematic comparison is complicated, because of
This, the operation energy consumption of whole system is the highest.It addition, also need to inject the water with slurry of desulfurizing agent in absorption tower, this is again
The unbalanced pressure of desulphurization system water can be increased, reduce the washing water quantity of demister.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, and operation energy consumption is low, and it is convenient to run, it is possible to subtract
The injection powder feeding integrated apparatus with slurry of the wet process of FGD of few desulphurization system water unbalanced pressure, to overcome prior art to deposit
Deficiency.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:
A kind of injection powder feeding integrated apparatus with slurry of wet process of FGD, it is characterised in that: include powder gas blender, penetrate
Water air ejector, serosity medial launder；The inlet end input agstone of described powder gas blender, inlet end input air, the port of export
Connecting the inlet end of described water jet air ejector, the ejection end of described water jet air ejector sprays gypsum slurries in water jet air ejector,
The port of export of described water jet air ejector is connected to described serosity medial launder, the bottom of described serosity medial launder and the stock tank of desulfurizing tower
Connection constitutes linker, and the top of described serosity medial launder has air vent.
In the present invention, the ejection end of described water jet air ejector is connected to described desulfurization tower slurry pool through water pump.So, jetting
Air ejector can directly extract the gypsum slurries of stock tank as injection liquid, the fluid flow so sprayed and pressure stability, and
Do not increase extra water with slurry when filling into desulfurizing agent, can effectively solve desulphurization system water balance.
Described air vent is communicates directly to above the stock tank within desulfurizing tower by exhaustor.Jetting so can be made to bleed
The air of device is directly entered in absorption tower, can effectively solve the soda pop that may take out of and a small amount of solid particle in the gas of ejection
Problem.
It is provided with piezometer on the pipeline in the inlet end front being positioned at described water jet air ejector.
It addition, the present invention also provides for a kind of injection powder feeding method with slurry of wet process of FGD, it is characterised in that:
By the stock tank of desulfurizing tower, it is provided with serosity medial launder, bottom described serosity medial launder, connects composition with described stock tank
Linker；
First carry out being mixed to form powder-gas mixture by agstone and air；
Then water jet air ejector is utilized to be sent in the middle of serosity by described powder-gas mixture by the way of injection gypsum slurries
Groove, in the process, agstone is sufficiently mixed with serosity in water jet air ejector, and air is arranged from described serosity medial launder top
Go out.
In a preferred embodiment, described water jet air ejector sprays the gypsum slurries extracted from described stock tank.
Described air is drained in desulfurizing tower.
Use technique scheme, present invention have the advantage that
1, spray feed is utilized directly the with slurry of agstone to be carried out in desulfurizing tower.
2, decrease limestone stock mixing system, reduce cost.
3, with slurry need not of limestone additionally moisturizes, and can effectively solve water balance.
4, the feed of gypsum slurries is consistent with former feeding system, the crystal region feed bottom absorption tower, does not affect desulfurization
The course of reaction of tower.
