Description

The microelectronics water treating device

The utility model relates to industry and civilian cooling water system, air-conditioning system, and heat exchange system, pipeline in the boiler systems etc. or the prevention of the incrustation scale in the container and the apparatus of removing, it belongs to the technical field of carrying out water treatment with physical method.

At civilian air-conditioner water system, in the systems such as heating water system and heat exchange, will produce incrustation scale in pipeline and the container after operation for some time, this is particularly outstanding in the harder area of water quality, the generation of incrustation scale and the result of use and the work-ing life of being on the increase meeting reduction system device, therefore, the incrustation scale of regularly removing in pipeline and the container is a requisite job.What now take usually is the way of matting, promptly use acidic solution flushing pipe and container, incrustation scale is decomposed to be removed, its shortcoming one is that matting eliminating thing has pollution to environment, the 2nd, chemical solution has corrosion to pipeline and molten device, the 3rd, the generation that can not eradicate incrustation scale must routine cleaning, waste of manpower and material resources.

The purpose of this utility model provides a kind of technology of handling incrustation scale with physical method, its principle is to flow into the water of system pipeline, the constant current electric field treatment of flowing through earlier, the structure of water molecules is changed, after the negative ions of dissolved salt is surrounded by single water molecules in the water, movement velocity reduces, effective collision to each other reduces, be unlikely and adhere to or combine in wall, for the wall of fouling, owing in the water molecules electronics that is energized is in a large number arranged, they will destroy the molecular structure of dirt, and incrustation is degraded gradually until removing.

The technical solution of the utility model is to put on electrode bar and the housing at the constant current source that is provided with metal electrode bar by tubular metal shell that is provided with intake-outlet and shell center and electronic generator is produced, current are behind the constant current electric field of shell and electrode formation, be under the basic structure of intensified processing, feature is: 1, different with traditional current stabilization circuit, adopt three end integrated voltage stabilizers to reach constant current output with the method for voltage stabilizing, and regulate the output constant current with the method for pressure regulation, avoided when outward current is big must be with powerful adjustable resistance adjusting electric current, the circuit specific design is: electric main is output plus terminal receiving electrode rod after step-down rectifier filtering, body skin connects the input terminus of three end integrated voltage stabilizers, the control end of three-terminal regulator block connects rectifying and wave-filtering output negative terminal by adjustable resistor, two shunting resistances of the output termination of three-terminal regulator block, wherein resistance goes out the upper end of termination adjustable resistance, be the control end of regulator block, the lower end that goes out the termination adjustable resistance of another resistance is a rectifying and wave-filtering output negative terminal.2, will have the body skin pipeline now and be divided into two sections pipes by one section homogeneous tube, between connect with the flange disk activity, to adapt to the installation adjustment of on-the-spot various different intake-outlets position.3, the solid electrode rod that will have metal titanium system now makes hollow titanium rod into, to economize on the material cost.

Below in conjunction with drawings and Examples utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is constant-current power supply circuit figure of the present utility model.

Referring to Fig. 1, be the metal tube body skin among Fig. 1,2 is water-in, 3 is water outlet, 4 is the titanium electrode at housing center, for economical with materials, electrode bar can be made hollow, wall thickness 3mm.After housing 1 made two sections with flange 5,6 interactions connect, what can adapt to different positions advances scenery with hills and waters mouth direction, 7 produce the Constant Electric Current field action behind the civil power on electrode and housing for constant0current generator connects, make the water 8 that enters by water inlet 2 flow out in the systems such as flowing into refrigeration again by water outlet 3 and can prevent and remove incrustation scale through intensifying processing, but and life-time service, exempted the shortcoming that matting must regularly be carried out.

Fig. 2 is the constant current source wiring diagram, civil power through after the transformer B step-down by rectifier D and filtering C after output plus terminal 1 receiving electrode, body skin connects the input terminus 2 of three end integrated voltage stabilizers, regulator block is selected CW317 for use, its control end 3 is by adjustable resistance R ₂Connect rectification output negative terminal, the output terminal 4 of CW317 meets two shunting resistance R ₁And R ₀, R ₁Go out termination R ₂The upper end, R ₀Go out termination R ₂The lower end.CW317, R ₁And R ₂Form a typical mu balanced circuit, regulate R ₂Can make output voltage V ₀Adjustable continuously in the 1.25-30V scope, because R ₀Be definite value, I ₀Also with V ₀Change, it is adjustable to reach electric current, to adapt to the required electric current of different water treatment amounts.For 300 tons of/hour water treating devices, 890mA constant current source, R ₁Select 220 Ω/0.25W resistance for use, R ₀Select 1.5 Ω/10W resistance for use, R ₂Select 200 Ω potentiometers for use.Because R ₂After value is fixing, V ₃Promptly stable, so I ₀Also be stationary value, and I ₁-I ₀+ I ₀, the I of CW317 ₀Variable quantity is very little only to be about 0.2 μ A, with the I about 1A ₀Compare and can ignore, thus I ₁Stable, the current stabilization that promptly flows through between electrode and shell reaches the purpose that water treatment is carried out in constant current output.This circuit is only used the adjustable integrated package of a slice 3 ends, and three resistance can reach the purpose of constant current output, the constant current accuracy height, and cost is low, and the circuit reliability height is because the excellent characteristic of CW317 piece also makes circuit have overcurrent, overheated and adjust function such as protection of pipe.
