Description

A kind of sea water system anti-blocking device

The utility model relates to a kind of sea water system anti-blocking device.

At present, boats and ships, offshore platform and strand Architectural Equipment etc., its sea water system is blocked by marine life, is the outstanding problem in the operational management always.Because marine life adhering to and grow in the sea water system at inwall; cause the pipeline effective diameter to dwindle seawater flow and do not reach design requirements; the condenser heat exchanger effectiveness reduces, and fuel oil consumption and maintenance cost and workload increase, even the serious consequence that causes shutdown, suspends.In addition, the sea water system corrosion of pipe also is its normal another difficult problem of using of puzzlement always.Measure is at the seainlet place of sea water system the metal electrode that can produce the poison material to be installed to above-mentioned situation current effective, with low-voltage DC to its electrolysis, produce that hypochlorous acid is received and poison material such as copper, enter among the sea water system, marine life is adhered to and growth is suppressed with flowing seawater.Existing this type of device mainly comprises the power controling box that the required low-voltage DC of electrolysis can be provided and can produce the metal electrode two parts of poison material, generally have three types: a kind of is to utilize titanium electrolysis seawater, generation hypochlorous acid is received, this mode is effective to the mariner growth prevent obstruction, but main shortcoming is that electrolysis current consumption is big.Another kind is to utilize copper, aluminium electrode, electrolysis produces copper one aluminium hydroxide flocculation material, this side adheres in sea water system and has certain anti-blocking and corrosion protection effect, but can only kill and wound macroscopical marine lifes such as barnacle mussel, and to unicellular bacterium and diatom mucus toxicological harmless effect, so that these biological attachment reduce the thermo-efficiency of condenser greatly.The third is to utilize titanium and copper electrode electrolysis to produce clorox and copper, this mode is much wide with copper more merely to the scope that marine life kills and wounds, yet its weak point one is cl concn control to be required tighter, concentration is too high to cause unnecessary a large amount of power consumptions, concentration is too for a short time not to have an effect, and its concentration all adopts the artificial mode to control to bring many inconvenience and accuracy relatively poor.

The purpose of this utility model be to provide a kind of biological to macroscopic views such as barnacle, mussels, unicellular and diatom mucus are all had fragmentation effect, and can adjust the sea water system anti-blocking device of chlorine ion concentration automatically.

For achieving the above object, sea water system anti-blocking device of the present utility model is made up of power source circuit and electrode, and power source circuit is made of 7 modules, they are respectively by L1, L2, L3, rectifier bridge D1, C1, the module 1 that C2 forms, mainly by transformer B1, rectifier bridge D2, ic chip 3, the module 2 that IC4 forms, by the module 3 of ic chip 1 for core control outward current, mainly by triode VT3, VT4, VT1, VT2, the module 4 that transformer B3 and diode are formed, by transformer B2, rectifying and wave-filtering, reometer, the constant current output module 5 that voltmeter is formed, by dual operational amplifier IC2 is the module 6 of the detection outward current of core, by dual operational amplifier IC5 is the module 7 of core, on module 7, be provided with chlorion sensing transducer port one, 2,3, be connected by the input terminus on the IC1 of the IC5 output terminal of module 7 and module 3; Electrolysis electrode is made up of three electrodes, and they are respectively copper electrode, aluminium electrode, titanium electrode, and is connected with the output terminal of module 5, and three electrolysis electrodes all are located at the seawater ingress of sea water system.

After adopting such structure, owing to used and be provided with three electrodes of forming by copper, aluminium titanium in the sea water system ingress, on module 7, be provided with the chlorion sensing become sending end port one, 2,3 just can enter biological, the unicellular and diatom of macroscopic view in the sea water system pipeline mucous kill and wound and suppress grow, the concentration of Faradaic current control chlorion be can regulate simultaneously automatically, thereby efficient power saving of sea water system anti-blocking and intelligentized effect reached.

Fig. 1 is the three electrode synoptic diagram that the position is set of the utility model,

Fig. 2 is pilot circuit figure of the present utility model.

As Fig. 1, sea water system anti-blocking device of the present utility model shown in Figure 2 is made up of power source circuit and electrode, and power source circuit is made up of 7 modules, they are respectively by L1, L2, L3, rectifier bridge D1, C1, the module 1 that C2 forms, mainly by transformer B1, rectifier bridge D2, ic chip 3, the module 2 that IC4 forms, by the module 3 of ic chip 1 for core control outward current, mainly by triode VT3, VT4, VT1, VT2, the module 4 that transformer B3 and diode are formed, by transformer B2, rectifying and wave-filtering, reometer, the constant current output module 5 that voltmeter is formed, by dual operational amplifier IC2 is the module 6 of the detection outward current of core, by dual operational amplifier IC5 is the module 7 of core, on module 7, be provided with chlorion sensing transducer port one, 2,3, be connected by the input terminus on the IC1 of the IC5 output terminal of module 7 and module 3; Electrolysis electrode is made up of three electrodes, and they are respectively copper electrode, aluminium electrode, titanium electrode, and they all are located on the clack box top board or strainer cover of seawater ingress of sea water system.During device work, controlling box produces chloride ion-containing and copper one aluminium hydroxide flocculation material to three electrolysis, when the chlorine ion concentration that enters pipeline is excessive or too small, the concentration of starting to control that promptly enters the setting of module 7 changes, IC5 converts electrical signal to by operational amplifier, deliver in the pulsewidth modulated intergrated circuit of module 3, adjust electric current output, the electric current on the electrode is adjusted on the concentration of the chlorion that meets setting.And the operational amplifier IC2 of module 6 detects outward current, error voltage is delivered in the pulsewidth modulated intergrated circuit of module 3, with the control outward current.Because the effect of module 7,6 and 3 and mutual UNICOM thereof, make that the electric current output of module 5 is constant, realized three electrodes by setting the electrolysis of electrolysis concentration, killed and wounded and suppressed biological, the unicellular and mucous growth of diatom of macroscopic view in the sea water system pipeline, made sea water system maintenance works better.
