Abstract
The utility model discloses an industrial acid and alkali adding wastewater treatment device. The automatic acid/alkali adding device comprises a control cabinet, an acid and alkali metering pump and a pipeline mixer through which industrial wastewater flows. The control cabinet comprises two online pH meters, a flowmeter, an industrial controller and four frequency converters; the monitoring points of the flowmeter, the monitoring points of the online pH meter and the adding points of the metering pump are arranged in front of and behind the pipeline mixer; the industrial controller is connected to the online pH meters, the flowmeter and the frequency converters through an electric signal line; the controller determines the acid/alkali addition amount through signals fed back by the online pH meters and the flowmeter and transmits the control signals to the frequency converters; and the motor speed of the metering pump is controlled by the frequency converters, thereby achieving the acid/alkali addition amount. By adopting advanced real-time control technology, the industrial acid and alkali adding wastewater treatment device greatly reduces the workload and the working requirements of operators for wastewater neutral adjustment caused by mutual acid/alkali addition, ensures the standard discharge of water out pH, and reduces the environment pollution.
Description
Technical field
The utility model relates to a kind of industrial acids alkali waste water treatment unit.
Background technology
Described in annex 1 document (2002 chief editor king tablet held before the breast by officials Cao associate editor Zou Qian Ping of " Iron And Steel Industry water supply and drainage design manual " Beijing metallurgical industry press get just Zhang Xuechao ten thousand shining halls) P656,657, P723 page or leaf, Iron And Steel Industry contains acid, alkali waste water and generally adopts the neutralization precipitation method to handle.Traditional wastewater treatment process is: waste water overflows to equalizing tank from the inclined tube pond, be pumped into neutralization tank by the equalizing tank process again, the operations staff passes through from neutralization tank sampling analysis PH data, whether artificial judgment needs adds acid/alkali and how long adds, the switching of Artificial Control dosing pump then makes wherein acid/alkali be added to neutralization tank and carries out water quality regulation.Because rolling effluent is an intermittent discharge, pumping waste water process is very fast, and it is big and untimely manually to chemically examine workload.Even an online PH table is installed, if rely on artificial experience and judgement to be regulated, still cause the efflux wastewater pH value fluctuated easily, be difficult to guarantee the qualified discharging of water outlet PH.
Summary of the invention
The purpose of this utility model provides a kind of device that adds acid/alkali automatically, avoids causing out the defective of water ph value by Artificial Control.
Automatically the device that adds acid/alkali comprises a housing, acid/alkali volume pump, the line mixer 13 that can pass through trade effluent.Wherein housing is made up of two online PH meters, under meter 1, industrial control unit (ICU) 12, four frequency transformers; Be provided with the monitoring point 2 ', 3 ' and the adding point 4 ', 5 ' of volume pump of under meter monitoring point 1 ' the online PH meter before and after the line mixer; Industrial control unit (ICU) is connected to online PH meter, under meter, frequency transformer by electrical signal, controller passes through the signal of online PH meter and under meter feedback, calculates to add acid/alkali number, and control signal is passed to frequency transformer, by Frequency Converter Control volume pump motor speed, thereby acid/alkali number what realization adds.
This device is by adopting advanced real-time control techniques, alleviated the operations staff greatly and manually added soda acid and carry out in the waste water and workload and the job requirement adjusted, guaranteed the qualified discharge of water outlet PH, reduced environmental pollution.Owing to adopt real-time control techniques, make the precision of PH span of control and stability all improve greatly simultaneously, thereby under the requirement that guarantees the environment protection standard discharging, reach the purpose of saving acid/alkali.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Automatically the device that adds acid/alkali comprises a housing, acid/alkali volume pump, the line mixer 13 that can pass through trade effluent.Wherein housing is made up of two online PH meters, under meter 1, industrial control unit (ICU) 12, four frequency transformers; Be provided with the monitoring point 2 ', 3 ' and the adding point 4 ', 5 ' of volume pump of the monitoring point 1 ' of under meter, online PH meter before and after the line mixer; Industrial control unit (ICU) is connected to online PH meter, under meter, frequency transformer by electrical signal, controller passes through the signal of online PH meter and under meter feedback, calculates to add acid/alkali number, and control signal is passed to frequency transformer, by Frequency Converter Control volume pump motor speed, thereby acid/alkali number what realization adds.Wherein, one of two online PH meter for feedforward PH meter 3, another counts 2 for rear feed PH.Acid/alkali volume pump has four, and wherein two for adding sour volume pump 8,9, and two for adding alkali volume pump 10,11 in addition.Have 4,5 controls of two frequency transformers to add the alkali volume pump in four frequency transformers, two frequency transformer 6,7 controls add sour volume pump.
As shown in drawings, the signal that industrial control unit (ICU) 12 feeds back according to monitoring point monitoring point 3 ' and under meter 11 ' of feedforward PH meter 3 at the beginning, it still is alkali volume pump 10,11 that decision earlier starts sour volume pump 8,9, promptly add acid or add alkali, calculate the amount that initially adds acid/alkali then, and control signal passed to frequency transformer 4,5,6,7, by actual the add acid/alkali number of frequency transformer by control volume pump motor speed control volume pump.Volume pump is from adding point 4 ', 5 ' acid/alkali that adds and waste water after line mixer 13 the inside thorough mixing reactions, detect in real time by 2 pairs of waste water of rear feed PH meter, and signal ceaselessly passed to industrial control unit (ICU) 12, industrial control unit (ICU) 12 according to the PH span of control of the signal of rear feed PH meter 2 and user's needs to adding the adjustment of acid/alkali number, and adjusted signal passed to frequency transformer, by the add acid/alkali number of frequency transformer, thereby realize dynamically within the limits prescribed the control of waste water pH value by control volume pump motor speed control corresponding measurement pump.When flow meter signal was zero, industrial control unit (ICU) sends instruction at once allowed all add acid/alkali pump stoppage in transit.When preventing from not have waste water to flow out, the acid and alkali corrosion pipeline.
