Description
Technical field
The utility model relates to a kind of aerating system energy saver that is applied to WWT, belongs to the sewage disposal device field.
Background technology
In the sewage treatment process, aerator is the vital equipment of sewage aerobic biological treatment system such as active sludge and bio-oxidation contact, and the aerator energy consumption is occupied very big proportion in the working cost of sewage work.Municipal sewage plant's energy consumption cost accounts for total expenses about 40%, and aerating system accounts for about 50% of energy consumption; Large-scale Sewage Treatment at Pharmaceutical Factory factory energy consumption cost accounts for total expenses about 60%, and aerating system accounts for energy consumption up to 65%; Therefore the energy-conservation of aerating system has crucial meaning to reducing the entire sewage processing cost.The adjusting of Aeration fan has following several method rotating speed adjustment, terminal valve to regulate, import and export stator adjustment etc., and general terminal valve is adjusted and the import and export stator is adjusted, and the control method limitation is big, and energy-saving effect is limited.And variable-frequency control technique is in the application of Aeration fan, and energy-saving effect can reach 15%.
The utility model content
According to above deficiency of the prior art; The technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective; Can monitor in real time aeration tank dissolved oxygen, and the convenient aerating system energy saver that is applied to WWT of regulating dissolved oxygen numerical value.
The utility model solves the technical scheme that its technical problem adopted:
A kind of aerating system energy saver that is applied to WWT comprises the sewage aeration pond, Aeration fan, PLC unit, upper computer, frequency transformer and dissolved oxygen meter; It is characterized in that: be provided with dissolved oxygen meter in the device and connect Aeration fan; Aeration fan connects the sewage aeration pond through aerated conduit, and dissolved oxygen meter is arranged in the sewage aeration pond, and the PLC unit is gathered the dissolved oxygen meter signal; Through upper computer dissolved oxygen numerical value is set, the PLC unit is through the Frequency Converter Control Aeration fan.
Said dissolved oxygen meter comprises temperature-compensating device, treats that the dissolved oxygen meter measurement numerical value of temperature compensation is accurate, reduces the influence of envrionment temperature to dissolved oxygen.
Described Aeration fan disposes frequency transformer.
The beneficial effect that the utility model had is: use simple; The aeration tank dissolved oxygen numerical value that will control through the upper computer setting; Monitoring is in real time automatically also controlled the running condition of Aeration fan through the PLC unit, guarantees that dissolved oxygen numerical value is in the reasonable technology numerical range all the time.Overcome the worth shortcoming that original manual shift is dissolved, energy-saving effect is obvious, and is safe and reliable, and level of automation is high, and is with low cost, has a good application prospect.
Description of drawings
Fig. 1 is the utility model frame principle figure;
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The described aerating system energy saver that is applied to WWT; Comprise sewage aeration pond 1, dissolved oxygen meter 2, PLC unit 3, upper computer 4, frequency transformer 5 and Aeration fan 6 is characterized in that: be provided with dissolved oxygen meter and chain Aeration fan in the sewage oxygen consumption treatment unit; Aeration fan connects the sewage aeration pond through aerated conduit 7; Dissolved oxygen meter is arranged on PLC unit collection dissolved oxygen meter signal in the sewage aeration pond, through upper computer dissolved oxygen numerical value is set, and the PLC unit is through the Frequency Converter Control Aeration fan.Dissolved oxygen meter has temperature compensation, treats that the dissolved oxygen meter measurement numerical value of temperature compensation is accurate, reduces the influence of envrionment temperature to dissolved oxygen.Frequency transformer can be through the signal of PLC, and the rotating speed of adjustment Aeration fan is adjusted fan delivery automatically, reaches energy-saving effect.
During use, through the dissolved oxygen numerical value that upper computer need be controlled to the input of PLC unit, dissolved oxygen meter transfers to the PLC unit with detected signal, and the PLC unit can come out detected dissolved oxygen numerical value again through screen displaying, realizes monitoring in real time.The PLC unit compares the dissolved oxygen numerical value of detected dissolved oxygen numerical value and input; If depart from the dissolved oxygen numerical value of setting; Then the PLC unit is regulated the dissolved oxygen numerical value of aeration tank through Frequency Converter Control Aeration fan rotating speed, and it is remained in the processing range that needs always; Guarantee the demand of technology, reach energy-conservation effect dissolved oxygen.
