The present invention be directed to the above existing issue of present galvanochemistry sewage disposal device, a kind of galvanochemistry wastewater treatment electrolysis power integrated control cabinet that proposes, make it by electric current and voltage monitoring, pH value monitoring, pressure monitoring, flow monitoring and temperature monitoring etc., the duty of monitoring sewage disposal process, reasonable regulation output, energy savings; And control two groups of electrolysis powers by PLC and regularly switch, make switch board to the positive and negative timing change poles of the output voltage of electric coagulation machine, solve electric coagulation machine pole plate scale problems.
The present invention is achieved by the following technical solutions, and the present invention comprises following content:
1, monitoring: the measured signals such as electric current and voltage, pH value, pressure, flow and temperature adopt corresponding sensor to detect, and the detection module of input PLC is realized the collection of measured signal after the conversion;
2, positive and negative change poles: adopt two groups of electrolysis powers (4,5) in the switch board of the present invention, two groups of electrolysis powers provide decomposition voltage for electric coagulation machine, every group of electrolysis power output terminal is connected in series a winding tentaculum separately, two main noddle on contactor front voltages are positive and negative opposite, and the rear end is in parallel, and two contactor control coils are connected in series mutually the opposing party's one group normally closed contact, form electrical interlocks, the break-make of contactor is controlled by PLC, and regularly switched conductive realizes the positive and negative change poles of electric coagulation machine pole plate.
3, man-machine interface: adopt industrial touch screen, realize demonstration, the control of switch board and the various data of electric coagulation machine and state, and can download by serial communication the data message of PLC record.
In sum, the present invention can realize the pH value monitoring of sewage, can reduce energy loss by the adjusting of man-machine interface electric current and voltage, can realize the positive and negative switching of voltage of electric coagulation machine pole plate, effectively stops the pole plate scale problems.
