Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by way of detailed description of the invention and in conjunction with accompanying drawing, the technical solution of the utility model is illustrated.
Embodiment 1
As it is shown in figure 1, the electrolysis dechlorination apparatus of a kind of ion exchange dechlorination waste water, including power supply 8, power supply 8 is connected to cell reaction groove 1, and cell reaction groove 1 connects absorber 2 by draw-out device 5, and absorber 2 connects formation chlorine closed circuit with cell reaction groove 1；Absorber 2 is communicated with crystallizing evaporator 4；Chlorine residual measurement instrument 7 it is provided with between cell reaction groove 1 and draw-out device 5；Absorber 2 is connected to absorption pump 6, is formed and absorb liquid closed circuit between absorber 2 and absorption pump 6；Cell reaction groove 1 is connected to adsorber 3.
When this utility model uses, cell reaction groove 1 pumps into ion exchange dechlorination waste water.Power-on 8, chloride ion oxidation is generated chlorine by the anode of cell reaction groove 1.Owing to oxidant need not be added, thus without producing solid slag, will not labor intensive.Chlorine absorption is entered absorber 2 by draw-out device 5 so that chlorine is absorbed.Residual exhaust is extracted device 5 and drives entrance cell reaction groove 1, drives newly generated chlorine to enter absorber 2, and chlorine is constantly absorbed, and forms chlorine closed circuit.
Absorber 2 is connected to absorption pump 6, is formed and absorb liquid closed circuit between absorber 2 and absorption pump 6, is so stirred absorbing liquid by absorption pump 6 so that the concentration absorbing liquid each several part keeps consistent, accelerates the absorption of chlorine.
It is continuously added iron powder in absorption liquid in absorber 2, ferric chloride is generated with chlorine reaction, after in absorption liquid, the concentration of ferric chloride reaches threshold value, the absorption liquid that crystallizing evaporator 4 extracts in absorber 2 is evaporated crystallization, obtain ferric chloride product, supplement the new liquid that absorbs simultaneously and make the concentration of ferric chloride in absorption liquid reduce.Reach the effect of zero release of pollutant.
Chlorine residual measurement instrument 7 measures the residual quantity of chlorine, when the residual quantity of chlorine is lower than the threshold value set, closes draw-out device 5 and absorption pump 6, opens adsorber 3, adsorbed by the chlorine of cell reaction groove 1 remnants.
Draw-out device 5 can be air exhauster or air pump etc..
Power supply 8 is preferably DC source, and such cell reaction groove 1 the two poles of the earth will not change, and the convenient product to the two poles of the earth is collected respectively.
Above are only a concrete guiding embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design that this utility model carries out unsubstantiality, the behavior invading protection domain of the present utility model all should be belonged to.
