Description
Technical field：The present invention relates to a kind of sulfuric acid concentration regulation dress in petrochemical industry, especially WSA sulphuric acid plants
Put.
Background technology：The caused concentrated sulfuric acid for 98wt% of condensation of sulfuric acid device pole in the case where environment temperature is less than 0 DEG C
Easy frozen plug pipeline, influences the positive production operating of device, while adds the entrucking difficulty during tank field stores.It is and existing
WSA sulphuric acid plants exhaust treatment system generation concentration must further be handled for 46wt% dilute sulfuric acids after incinerator burns can
Qualified products are converted into, and enter easily to cause the big amplitude wave of whole system temperature and moisture while incinerator burns in dilute sulfuric acid
It is dynamic, even result in the chain jump car of WSA devices.
The content of the invention：The object of the invention provides a kind of sulfuric acid concentration adjusting means to solve above technical problem.
The present invention is realized by following technological means：A kind of sulfuric acid concentration adjusting means, by condensation of sulfuric acid device, urgency
Cold tower, incinerator, sour pump, sulfuric acid pans, acid cooler and connecting pipeline pump valve and control system composition, wherein the sulfuric acid
Condenser sulfuric acid output end pipeline is connected with sour pump, cooler, and sulfuric acid pans, the condensation of sulfuric acid device condensation end in turn
Pipeline is sequentially connected chilling tower, chilling pump, incinerator, acidity in-line analyzer, institute is provided with the port of export pipeline of sour pump
State sour pump discharge pipeline and be provided with the reflux pipeline being connected with incinerator inlet adjustment valve input pipeline, the regulating valve and acid
The control signal end of degree in-line analyzer is connected by control line with control system.
Beneficial effect of the present invention：Method by reducing sulfuric acid concentration reduces concentrated sulfuric acid freezing point, moreover it is possible to is by washing
Finished product dilute sulfuric acid is converted into the finished product concentrated sulfuric acid caused by system, reduces the fuel gas caused by dilute sulfuric acid burns and consumes, enters
One step reduces the energy consumption of device, while has prevented system temperature and moisture caused by dilute sulfuric acid enters incinerator burning significantly
Ripple
Brief description of the drawings：Fig. 1 is schematic structural view of the invention；

End pipe line is connected with sour pump 4, cooler 6, and sulfuric acid pans 5 in turn, and the condensation end pipeline of condensation of sulfuric acid device 1 connects successively
Chilling tower 2 is connect, chilling pump 8, incinerator 3, acidity in-line analyzer 7, the sour pump are provided with the port of export pipeline of sour pump 3
3 outlet lines are provided with the reflux pipeline being connected with the input pipeline of 3 inlet adjustment valve of incinerator 10, are provided with reflux pipeline
Reflux pipeline regulating valve 9, the regulating valve 9 pass through control line with regulating valve 10 and the control signal end of acidity in-line analyzer 7
It is connected with control system.The course of work of the present apparatus is that dilute sulfuric acid caused by the washing system of chilling tower 2 is led into sour cyclic system
The sour pump 4 of system exports (being herein the 98wt% concentrated sulfuric acid), and output 93wt% sulfuric acid is allowed to by the injection of dilute sulfuric acid, during which sharp
Finished product acid concentration is monitored in real time with the acidity in-line analyzer 7 of acid circulation system, and control system is set according to the concentration of line analysis instrument 7
Select the entrance incinerator 3 of dilute sulfuric acid by adjusting regulating valve 9 with the dilute sulfuric acid of regulating valve 10 or entered by reflux pipeline
With the dilution pipeline of the concentrated sulfuric acid.
