Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, so that the technology of this field
Personnel can be better understood from advantages and features of the invention, to make apparent boundary to protection scope of the present invention
It is fixed.Embodiment described in the invention is only a part of the embodiment of the present invention, instead of all the embodiments, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained without making creative work
Example, shall fall within the protection scope of the present invention.
Embodiment
The former control mode of oxidation solution storage tank is as follows：Oxidation solution after the completion of the reaction of DC device oxidizing towers, is cooled to 70
DEG C or so after be transferred to oxidation solution storage tank, but the storage tank does not have temperature control and urgent interlock program.Therefore, former control mode by
There is no temperature control loop in oxidation solution storage tank, it is larger to be easy to cause oxidation solution fluctuation range of temperature in storage tank, while
Master control and the fluctuation of service of Field Force can be caused, point water conservancy project sequence is influenced and restores the operational stability of process.Moreover, by
When no urgent interlock program of setting, oxidation solution mid-winter, if failing to squeeze into urgent water cooling in time, it is likely to result in
Serious industrial accident.
In view of the above-mentioned problems, the present invention provides a kind of temperature control being exclusively used in oxidation solution storage tank and urgent interlock program
