Description
Technical field
The utility model relates to chemical emission process field, and in particular, the utility model relates to a kind of pH value circulation supervisory system.
Background technology
At present, in waste gas treatment process, adopt liquid absorption process comparatively common, such as carry out packed tower or rotating stream tray scrubber inverse spray circulation fluid to acid waste gas to absorb, and generally the pH value of absorbing liquid needs to control, otherwise be difficult to the effect that ensures to absorb and stability, the detection of pH value needs to be completed by pH meter, thus the installation site of pH meter is particularly important, as install unfortunately when, the problem such as inaccurate detected may be caused.Conventional bottom pH meter being all arranged on to spray column, i.e. the liquid level region of circulation groove.This mounting means may bring many-sided problem in actual use, when pH meter needs to safeguard or change, circulation groove liquid level must be put to pH meter height, because the uncertainty of operation, so cause waste and the time waste of circulation fluid, special in tower diameter is larger, discharge cycle liquid needs for a long time.Meanwhile, because tower body is comparatively large, the mixing of circulation tank liquor is changed not in time, and cause pH value to occur delayed, system is matched add alkali or add acid function can not be implemented in time, have impact on the absorptive character of circulation fluid.
Utility model content
The purpose of this utility model is to solve existing above-mentioned problem, provides a kind of pH value circulation supervisory system.
For realizing above object, the technical solution of the utility model is a kind of pH value circulation supervisory system, comprise absorption tower and ebullator, absorption tower is connected with ebullator formation major loop, it is characterized in that, described circulating-pump outlet is provided with circulation branch road, described circulation branch road is provided with flow cell, and described flow cell water inlet pipe is provided with operation valve, and described flow cell top is provided with pH meter, described pH meter is fixedly connected with flow cell, and flow cell rising pipe is connected with absorption tower.The operation valve on circulation branch road is utilized to regulate the circulating fluid flow rate flowing into flow cell, the circulation fluid flowing into flow cell measures the pH value of circulation fluid by pH meter, the circulation fluid of flow cell flows back to absorption tower by flow cell rising pipe, when pH meter needs to safeguard or change, closed control valve, discharges the circulation fluid of flow cell inside, just can safeguard or change pH meter, so both can safeguard or change pH meter, not affecting again the normal operation on absorption tower.
As preferably, described flow cell bottom is provided with blow-off pipe, and described blow-off pipe is fixedly connected with flow cell, and described blow-off pipe is provided with blowoff valve.When needing blowdown, open blowoff valve, by blow-off pipe, the sewage in flow cell is discharged.
As preferably, described flow cell rising pipe is provided with valve, and described valve is fixedly connected with flow cell rising pipe.When safeguarding or change pH meter, the valve on flow cell rising pipe refluxes for preventing the circulation fluid of inside, absorption tower.
As preferably, described flow cell bottom is funnel-form.Flow cell lower hopper shape, facilitates sewage to discharge.
As preferably, described inside, absorption tower is provided with spraying layer, and described spraying layer is connected with major loop water inlet pipe, is provided with processing layer below described spraying layer, and described processing layer is fixedly connected with absorption tower.The circulation fluid of major loop sprays processing layer by spraying layer, and circulation fluid processes by processing layer, finally flows back to bottom absorption tower.
As preferably, the major loop of described circulating-pump outlet is provided with variable valve, and described variable valve is fixedly connected with major loop.Variable valve on major loop can regulate circulating fluid flow rate, regulates like this according to need of production.
As preferably, described absorption tower side is provided with exhaust gas inlet pipe, and described exhaust gas inlet pipe is fixedly connected with absorption tower.Such convenience carries out maintenance and repair to absorption tower.
The utility model has following beneficial effect: when pH meter needs to safeguard or change, closed control valve, discharges the circulation fluid of flow cell inside, just can safeguard or change pH meter, so both can safeguard or change pH meter, not affecting again the normal operation on absorption tower.
