(influent turbidity transmitter 10 and delivery turbidity transmitter 14) and liquid level sensor 20 etc., and these data acquisition equipments are installed on the seawater cleaning system pipes of seawater coagulation separator for removing dirt pipeline.The output terminal of PLC unit 21 is connected with pump valve equipment, and these pump valve equipment comprise raw water pump (first raw water pump 6 and second raw water pump 7), dosing pump 15 (flocculation agent dosing pump and coagulant aids dosing pump), mud valve 18 and sludge circulation pump 19 etc.While PLC unit 21 is also controlled change-over switch 2, equipment state PL 4 etc. automatically through I/O interface and touch-screen 3, power switch 4, hand and is connected.PLC unit 21 is according to the data that data acquisition equipment collected, to various pump valve equipment output waves.
Emergent manual control circuit is manually controlled total system through manual control mode, and emergent manual control circuit is controlled change-over switch 2 automatically with the hand on the control panel and linked to each other.When automatic control system is out of order, can hand controls change-over switch 2 automatically and switch to manual control mode total system is controlled.Come opertaing device thereby make automatic control system have manually with automatic two kinds of operating method, guaranteed the continuous firing of seawater coagulation separator for removing dirt to the full extent, make system have the continual and steady characteristics of water quality.
This seawater coagulation separator for removing dirt automatic control system is connected through various data traps and the equipment that PLC unit 21 will be installed on the seawater coagulation separator for removing dirt pipeline; The various parameters of gathering former seawater through data trap on the one hand; Various data to gathering are carried out analyzing and processing; The corresponding result that obtains through search knowledge base; And various device controlled automatically; Thereby realize interlock control, handle former seawater, guarantee to handle the water quality of back seawater with the dose that adds of optimum to raw water pump (first raw water pump 6 and second raw water pump 7), dosing pump 15 (flocculation agent dosing pump and coagulant aids dosing pump), mud valve 18 and sludge circulation pump 19 etc.Said process all is that the automatic control by PLC unit 21 realizes; And when manually controlling, operator can operate through 5 pairs of various water treatment device of the hand control switch knob on the operation control panel.In whole process, the working order of various device all can show through touch-screen 3 or equipment state PL 4 and offer operator.
In PLC unit 21, embedding has expert database system, and corresponding knowledge base is arranged in this experts database.PLC unit 21 can be according to the data that data acquisition equipment collected, the knowledge of the corresponding seawater coagulation of search turbidity removal from knowledge base in real time, and PLC unit 21 obtains after the sensor signals according to the controlled signal of knowledge base.If the knowledge in the knowledge base is not enough, can in knowledge base, import the more knowledge data through the staff; And when there is mistake in the knowledge in the knowledge base, also can change the knowledge data in the knowledge base through the staff.
The working process of this seawater coagulation turbidity removal automatic control system is:
At first, in the tank 8 shown in Fig. 2 liquid level detecting sensor is housed, can sends the water level information in the tank 8 to PLC unit 21 in real time.When liquid level detecting sensor when the signal of PLC unit 21 transmission shows that water in the tank 8 is in high liquid level, then PLC unit 21 controls first raw water pump 6 closes, second raw water pump 7 is opened; When liquid level detecting sensor when the signal of PLC unit 21 transmission shows that water in the tank 8 is in median water level, then PLC unit 21 control first raw water pumps 6 and second raw water pump 7 are opened simultaneously; When liquid level detecting sensor when the signal of PLC unit 21 transmission shows that water in the tank 8 is in low-water level, then PLC unit 21 controls first raw water pump 6 is opened, second raw water pump 7 closes.
Second step; After raw water pump 6 is opened; Be contained in the information such as temperature, turbidity, flow that TP 9, influent turbidity transmitter 10 and flow sensor 11 between raw water pump 7 and the line mixer 12 begins to gather former seawater, the information that is collected is sent to PLC unit 21.After being judged as useful signal, PLC unit 21 begins to search for its inner knowledge base, obtains the amount of required flocculation agent 17 and coagulant aids 16 medicaments under the present case, and converts the flow control electrical signal of dosing pump 15 to.If PLC unit 21 does not find needed knowledge under the current situation, then the notifications operator add corresponding knowledge, so that automatic control system can be used corresponding knowledge.
In the 3rd step, the mixing seawater that former seawater, flocculation agent 17 and coagulant aids 16 are produced behind the thorough mixing in line mixer 12 is delivered to coagulating sedimentation device 13 through pipeline, and three groups of mud valves 18 and mud circulation pump 19 are housed on the coagulating sedimentation device.In PLC unit 21, there is special batch processing to control three groups of mud valves 18 and opens spoil disposal successively, and after spoil disposal is accomplished, close immediately according to a graded.PLC unit 21 control mud circulation pump 19 unlatchings and closures are back in the coagulating sedimentation device 13 mud in the spoil disposal pond 22 to promote the deposition of suspended substance in the mixed solution simultaneously.
In the 4th step, the turbidity of the cleer sea water that delivery turbidity transmitter 14 will be handled feeds back to PLC unit 21, comes whether the turbidity of seawater meets the demands after the judgment processing, if satisfied then remind operator to readjust the relevant knowledge in the knowledge base.
At last, when carrying out manual control mode, operator can directly control the various device in the system directly through the hand control switch knob 5 on the operation control panel, reach system's quantity-produced purpose.
The sensor parameter is a union relation, and when all parameters all met the demands, PLC unit 21 control flocculation agent dosing pumps was automatically worked with the coagulant aids dosing pump, former seawater after the processing is reached or is lower than predetermined turbidity value.
The seawater coagulation separator for removing dirt automatic control system that the utility model provides through use PLC unit 21 with various data acquisition equipments, pump valve equipment is organic links together; Wherein data acquisition equipment can detect the water quality parameter of former seawater; Through PLC unit 21 these parameters are carried out analyzing and processing; Automatically the operation of control various device; Realize the automatic control of former seawater cleaning process, guarantee to handle the water quality of back seawater, whole system has unmanned, level of automation is high and the characteristics of real-time control.Through increasing the knowledge of knowledge base, make this seawater coagulation separator for removing dirt system can tackle the former seawater that turbidity changes, so this automatic control system have suitable turbidity variation greatly, the characteristics that adaptive ability is strong.
