Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in detail by embodiment.
As it is shown in figure 1, a kind of combination type decontamination waste liquid chlorine residue is removed system, more than control system 1, pump 8 and combination type
Chlorine filtration system, pump 8 is connected by the pipeline being attached in combination type chlorine residue filtration system with combination type chlorine residue filtration system, described
Combination type chlorine residue filtration system includes the most interconnective ultraviolet dechlorination device 2, activated carbon dechlorination device 3, ormolu
Dechlorination device 4 and modified resin dechlorination device 5, in combination type chlorine residue filtration system, the junction of each device is equipped with opening and closing
Valve (electromagnetic valve or/and check valve 14).
Ultraviolet (UV) model in described ultraviolet dechlorination device 2 is Germany's IST 254 nanometer UV.
Activated carbon, copper zinc in described activated carbon dechlorination device 3, ormolu dechlorination device 4 and modified resin dechlorination device 5
Alloy and three kinds of filtrates of resin are commercial goods, are respectively put in the storage container of identical external form performance dechlorination effect.
Import department at described activated carbon dechlorination device 3 is provided with the first on-line detector 6.
The exit of described modified resin dechlorination device 5 is provided with the second on-line computing model 7.
Described control system 1 is mainly made up of converter, industrial computer, PLC.
PLC, as the computing in control system and controlling organization, comprises a pressure transducer, according to pressure at pump discharge
Sensor transmissions contrasts to the 4-20mA Signals & Systems setting value of PLC, and defeated to converter by analogue signal module
Entering an analogue signal, converter is energized to by control pump according to after analogue signal regulating frequency, thus reaches to control water pump and turn
The purpose of speed.Industrial computer is display module, by netting twine and PLC phase liaison, takes the dynamic data of PLC, is existed by wincc program
