Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Recirculated water automatic sterilizing apparatus for eliminating sludge comprises reaction chamber 15, water-in 4 and water intaking valve 7, water outlet 5 and outlet valve 10, sewage draining exit 6 and wash water valve 8, anode 1, Controlling System 17, end cap 11, support 16; Be provided with test electrode 9 in the reaction chamber 15, reaction chamber 15 is a metallic substance, and its inwall links to each other with cathode terminal 2 as the negative electrode of electrolytic reaction; Anode 1, test electrode 9 pass and are fixed on the end cap 11, test electrode 9 is near the inwall of reaction chamber 15, the outer wall of reaction chamber 15 is coated with the grommet epoxy layer and ultrasonic cleaner 3 is installed, and the bottom of reaction chamber 15 is sphere or pyramid type, and its internal surface is coated with the grommet epoxy layer.
State during work as shown in Figure 1, the inwall of reaction chamber 15 serves as the negative electrode of electrolytic reaction, links to each other with cathode terminal 2 electricity; Current density on the negative electrode can reach 10A/m
2Reaction chamber 15 can adopt metallic substance such as carbon steel, stainless steel or aluminium, and its outside surface has the Resins, epoxy protective layer, has electrical isolation and preservative activity; The bottom of reaction chamber 15 is sphere or pyramid type, and its internal surface is coated with the grommet epoxy layer, avoids adhering to incrustation scale in the reaction chamber bottom, has preservative activity simultaneously; There is water-in 4 lower end, reaction chamber 15 side, and there is water outlet 5 upper end, opposite flank, and sewage draining exit 6 is arranged at the bottom.
Anode 1 is 1-3, and present embodiment is got 2, and its length equates with the straight wall height of reaction chamber 15; And pass end cap 11 and sealing-ring 12 places in the reaction chamber 15.Electrolytic reaction is carried out fully.
Test electrode 9 passes end cap 11 and sealing-ring 12 places in the reaction chamber 15.End cap 11 carries out fit sealing with the top of reaction chamber 15 by bolt 13 and sealing-ring 12.
Ultrasonic cleaner 3 is 3-6, and present embodiment is got 3, is evenly distributed on reaction chamber 15 sidewalls.
Anode 1, cathode terminal 2, ultrasonic cleaner 3, test electrode 9 link to each other with Controlling System 17 by the control cable.
Water intaking valve 7 is housed on the water-in 4, outlet valve 10 is housed on the water outlet 5, wash water valve 8 is housed on the sewage draining exit 6, water intaking valve 7, outlet valve 10, wash water valve 8 link to each other with Controlling System 17 by the control cable.Water intaking valve 7 and outlet valve 10 are often to open by-pass valve control, and wash water valve 8 is normally closed by-pass valve controls.Water intaking valve 7, wash water valve 8 and outlet valve 10 can be pneumavalve or motorized valve.
Control section in the Controlling System 17 is controlled with micro-chip or programmable logic controller (PLC).
The calcium magnesium incrustation scale 14 of separating out in advance directly is deposited on reaction chamber 15 inwalls, and reaction chamber 15 is fixed on 3 legs or 4 leg supports 16.
Recirculated water automatic sterilizing apparatus for eliminating sludge has two working ordeies: treated state and cleaning state.
Under treated state: processed water flows into this device from water-in 4, and the water after processed flows out these devices from water outlet 5.After this device starts, the inwall of reaction chamber 15 is as producing electrochemical reaction between the negative electrode of electrolytic reaction and the anode 1, can in advance the calcium in the water, magnesium ion be converted into insoluble mineral substance is that incrustation scale 14 is deposited on the inwall of reaction chamber 15, be what is called fouling in advance, near the chlorine of separating out the anode 1 has the effect of killing bacteria and algae simultaneously.
Under the cleaning state: measure the incrustation scale degree on the inwall of reaction chamber 15 by test electrode 9, when reaching certain set(ting)value, under the control of Controlling System 17, close water intaking valve 7 and outlet valve 10, start ultrasonic cleaner 3, the mechanical energy of utilizing ultrasonic wave to produce is cleaned automatically to reaction chamber 15, and the incrustation scale 14 on reaction chamber 15 inwalls is removed, open wash water valve 8 and water intaking valve 7 then, the incrustation scale in the reaction chamber 15 is rinsed well, also discharged incrustation scales by wash water valve 8.Close ultrasonic cleaner 3 at last, and close wash water valve 8, open outlet valve 10, recover treated state.
In conjunction with the accompanying drawings specific implementation method of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
