Description
Technical field
The utility model relates to a pH value pick-up unit, relates in particular to a kind of for plasm PH value pick-up unit in desulfurizer in wet desulfurizing process.
Background technology
Along with country is to the attention of environmental protection, controls more and more stricter to the pollutant sulphuric dioxide in steel mill's sinter fume discharge, strict demand is proposed to sintering desulfuration system stable operation.Sintering desulfuration system cloud gray model requires to control in real time plasm PH value in desulfurizer, in tower, plasm PH value is the critical data controlling desulphurization system operation, have influence on joining day and the addition of desulfurizing agent, the observation of impact to slurries sulfur dioxide absorption effect in tower, PH pick-up unit can for a long time, stable, run accurately, can decide desulphurization system normally run.A lot of desulphurization system is adopted and is detected pH value change in tower in two ways at present, and one is adopt PH value detector table to be directly installed on desulfurizer, and two is be disposed to ditch after drawing slurries to external detection in tower.First method PH measuring instrument is not easily changed after damaging, and instrument is in Ta Neiyi fouling.Second method is outer for a long time arranges slurries in tower, causes desulfurizing agent to waste and trench drain corrosion, without instrument and pipeline-cleaning measure, easily causes obstruction.
Utility model content
In view of the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of for plasm PH value pick-up unit in desulfurizer in wet desulfurizing process, this pH value pick-up unit can working fluid pH value in Real-Time Monitoring tower, arrange outward without slurries, conveniently can rinse detection system, change instrument convenient.
To achieve these goals, plasm PH value pick-up unit in a kind of desulfurizer that the utility model provides, described desulfurizer is connected with slurry circulating pump, described pH value pick-up unit comprises detection tank, pH value meter, slurries feed tube and slurries liquid back pipe, described detection tank is respectively arranged with pH value meter mounting interface, slurries inlet port and serum outlet; One end of described slurries feed tube is connected on described slurries inlet port, and the other end is communicated with on described desulfurizer for slurries being imported to described detection tank; One end of described slurries liquid back pipe is connected on described serum outlet, and the other end be communicated with on described slurry circulating pump for by slurry reflux to described desulfurizer.
As preferably, described detection tank being also provided with a Butterworth Hatch, described Butterworth Hatch being connected with a wash tub pipe for cleaning described detection tank.
As preferably, described detection tank is also provided with a sample tap, described sample tap is connected with a stopple coupon for Real-Time Monitoring plasm PH value.
As preferably, described slurries feed tube and described slurries liquid back pipe are provided with the butterfly valve for controlling flow; Described wash tub pipe and described stopple coupon are respectively arranged with a ball valve.
As preferably, described detection tank, slurries feed tube, slurries liquid back pipe, wash tub pipe and stopple coupon are glass steel material or adopt glass steel material coated.
Adopt plasm PH value pick-up unit in desulfurizer of the present utility model, PH can be avoided to detect inaccurate, prevent PH instrument from damaging, prevent pick-up unit fouling, obstruction, without outer plasma discharge liquid, ensure that the reliability that pH value detects, extend the service time of PH instrument, facilitate outer samples and instrument to change.Meanwhile, pick-up unit uses fiberglass to make, and technique is simple, and fabrication cycle is short, and cost is low.Substantially increase the stability that desulphurization system pH value detects.
