Embodiment
Below in conjunction with accompanying drawing, preferred implementation of the present invention is described.
Fig. 1 is the circuit block diagram of sweep frequency electromagnetic field generator of the present invention.As shown in Figure 1: the sweep frequency electromagnetic field generator that the present invention relates to is made up of power supply 100, control signal producer 200 and switch amplifying circuit 300.
Wherein power supply 100 is made up of DC constant current source 11, DC15V power supply 12 etc.
Control signal producer 200 is made up of sweep generator 1, scanning frequency pulse producer 2, control signal work indication 3 and pulse amplifier 4 etc.
Switch amplifying circuit 300 comprises compositions such as switch circuit 5, primary processor 6, the auxilliary treater 7 of deionization and blowdown pilot circuit 8.
The working process of this sweep frequency electromagnetic field generator is as follows:
It is civilian that system inserts 220V, after the energising, sweep generator 1 generation amplitude is 15V, and frequency is the repetition zigzag wave of 100HZ, this zigzag wave is applied on the scanning frequency pulse producer 2, thereby produces as shown in Figure 2 pulse width L and the scanning frequency pulse string that all changes of period T.Above-mentioned scanning frequency pulse string is applied to the control end of switch circuit 5 after pulse amplifier 4 amplifies, switch circuit 5 outputs to output rating scanning frequency pulse string on the primary processor 6, and imports into to processed water, produces the scanning frequency pulse electromagnetic field in water.
In addition, according to according to fourier series:
A(t)＝A0+A1Sinωt+A2Sin2ωt+......+AnSinnωt+......
Individual pulse in the above-mentioned scanning frequency pulse string by direct current A0 and many times sinusoidal oscillation form.In these sinusoidal oscillations, the amplitude of fundamental frequency and second harmonic is higher.
As previously mentioned, the electrical signal that imports in the water is the scanning frequency pulse string, and the pulse of distinct pulse widths and frequency has different fundamental frequencies and second harmonic.Can reach a conclusion thus: acting on pending industry and the electrical signal in the domestic water simultaneously has direct current and multiple sinusoidal oscillation signal.
For the pending water that contains algae and bacterium, high-frequency signal (swept frequency range of scanning frequency pulse string is 4-25KHz) can make the cellular elements of algae or bacterium vibrate, cause cell wall rupture, cell content matter flocks together, and make algae and bacterium death, thereby reach the purpose of sterilization algae removal.
Pending water must have the bacterium and the algae of different varieties because the region is different with water quality.The bacterium of these different varietiess and algae have different susceptibility to the frequency of high-frequency signal.The present invention is owing to adopted scanning frequency pulse, be that the pulse signal frequency that signal generator produces is a continually varying, make that import signal spectrum in pending into distributes very widely, the high frequency component signal of various different frequencies is arranged, therefore can kill each bacterioid and algae in the pending water.
Among the present invention, the positive pole of primary processor 6 is made of metallic aluminium, and the flip-flop in the scanning frequency pulse string will be to the effect of producing electrolysis of aluminium positive pole, and Xiang Shuizhong discharges aluminum ion.Aluminum ion is the fine flocculation agent, pending industry and the colloid in the domestic water, molecule there is the intensive throwing out, become larger particles sinking or come-up after can making the flocculation of pending industry and the colloid in the domestic water and molecule, after these bigger particles filter through strainers, be filtered that device is caught and discharge from sewage draining exit.Therefore, the present invention also has the function of purification of water quality except that the function with sterilization algae removal.
Fig. 3 is for using the system schematic that sweep frequency electromagnetic field generator of the present invention carries out the water treating equipment of sewage disposal.As shown in Figure 3, water treating equipment of the present invention are constructed as follows:
Pending water flows into by suction culvert and water intaking valve 13, is pumped to water treating equipment of the present invention by pump 20 and handles.Water treating equipment are made of the auxilliary treater 7 of main frame 400, primary processor 6 and deionization.Main frame 400 is exported and export direct currents to the auxilliary treater 7 of deionization to primary processor 6 output pulse outputs.The auxilliary treater 7 of primary processor 6 and deionization can place the pipeline of pending current warp, and the positive pole of primary processor 6 and deionization auxiliary processor 7 contacts with water with negative plate, and water is handled.Treated water is discharged through strainer 22 and outlet valve 14, and the dirt that filters out is discharged by catch basin 24 and wash water valve 15.
The purpose that the present invention is provided with auxilliary treater 7 of deionization and blowdown pilot circuit 8 is in order to prevent the metal ion pollution water body, to eliminate secondary pollution.
The positive pole of the auxilliary treater 7 of deionization is made with the nonexpendable material of electrolysis (for example carbon).During work, be connected with volts DS between positive and negative electrode, when the metal ion that has a positive charge is flowed through between the positive and negative electrode, will be caught by negative pole.
As Fig. 1 and 3, the effect of blowdown pilot circuit 8 is: regularly (for example every 2 hours), regularly to close the power supply of the auxilliary treater 7 of deionization (for example each 5 minutes), and close outlet valve 14, wash water valve 15 is opened, and device is carried out blowdown.After the blowdown 5 minutes, device recovers auxilliary treater 7 energisings of deionization again, and outlet valve 14 is opened the working order that wash water valve 15 cuts out.
Primary processor 6 of the present invention all can be made dentation with the positive pole of the auxilliary treater 7 of deionization.The purpose of tooth punching is: the first, increase the anodal specific surface area; The second, according to the principle of point discharge, in water, produce the boundling electric current, increase the current density of regional area, with the effect that strengthens sterilization algae removal and collect metal ion.
In addition, sweep frequency electromagnetic field generator of the present invention also can be exported the scanning frequency pulse electromagnetic field that does not contain DC component, this means that pending water can obtain handling by scanning frequency pulse electromagnetic field and DC electric field successively.This also is conspicuous to those skilled in the art.Its principle and explanation no longer repeat herein.
