In order to achieve the above object, the technical solution adopted in the utility model is: be equiped with audio signal source and power amplifier in the main frame, the signal output part of power amplifier is connected with the signal input wires terminal of magnetostrictive transducer by cable, the exterior vibration sensor is loaded on the magnetostrictive transducer, its with main frame between be connected by the transducing signal treatment circuit, described ultrasonic signal source by six road ultrasonic wave special IC U601 extremely peripheral cell form, produce the ultrasonic signal of 11KHz-75KHz frequency adjustable, and by PA, PB, PC, PD exports in the IGBT drive circuit, wherein, U601 the 16th pin is connected with resistance R 607, R607 is connected with multiturn potentiometer R608, and R607 connects with R608 and be in parallel with capacitor C612.
The utility model has the advantages that:
(1) the employed water of the utility model need not carry out the chemical tendering processing, has saved capital construction, has bought enormous expenditures such as chemical agent and operation maintenance;
(2) the utility model antiscale and descale effect are obvious, make boiler and heat exchanger remain at the operation down of best state, have reduced the energy loss of enterprise, have improved the economy and the security of equipment operation, online antiscale of the equipment of having realized and scale removal;
(3) the utility model has reduced owing to fouling attaches the corrosion that the rust deposite that causes and gas cause, the service life of having improved equipment;
(4) little, in light weight, the simple installation of the utility model volume, do not need to change and destroy the structure of boiler and heat exchanger;
(5) break time of this device discontinuous pulses can be adjustable continuously, at interval can be from the continuously adjustable impulse train of 40MS to 120MS, thus can satisfy the antiscaling, descaling needs of different dirty things.Make ultrasonic pulse antiscaling, apparatus for eliminating sludge have best antiscale, scale removal ability.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1 one Fig. 5 as can be known, be equiped with audio signal source and power amplifier in the utility model main frame 1, the signal output part of power amplifier is connected with the signal input wires terminal of magnetostrictive transducer 2 by cable, exterior vibration sensor 3 is loaded on the magnetostrictive transducer 2, its with main frame 1 between be connected by transducing signal treatment circuit 4, described ultrasonic signal source by six road ultrasonic wave special IC U601 extremely peripheral cell form, produce the ultrasonic signal of 11KHz-75KHz frequency adjustable, and by PA, PB, PC, PD exports in the IGBT drive circuit, wherein, U601 the 16th pin is connected with resistance R 607, R607 is connected with multiturn potentiometer R608, and R607 connects with R608 and be in parallel with capacitor C612.
Described IGBT drive circuit is formed by 4 the tunnel, every part all is made of core optocoupler U51-U54 and outer member thereof, wherein in the optocoupler of interface J515, the J525 of U601, J535 and J545 difference connection interface U51, U52, U53 and U54, the base stage of switch triode Q511, Q521, Q531, Q541 is connected to current-limiting resistance R514, R524, R534 and R544, and IGBT drive circuit output J512, J513-J542, J543 are connected to power take-off G1, E1-G4, E4 end with twisted-pair feeder.
The utility model this device main frame 1 control under, the ultrasonic wave that produces is changed in the tube bank and the water in the pipeline that ultrasonic vibration affacts boiler and heat exchanger by magnetostrictive transducer 2, make water generates ultrasonic coagulation phenomenon, promptly being suspended in granulometric impurity aggegation in the water becomes the nodule of larger particles and precipitates, because metal pipe-wall is different to the frequency response of ultrasonic vibration with water, therefore, produce relative motion at a high speed between metal and the water, make the surface that cements in tube wall that the nodule of larger particles at all can't be static, but be rendered as the suspension floccule, these floccules can be got rid of easily by blowdown, have reached the purpose of antiscale with this.Ultrasonic vibration acts on the metallic conduit and heating surface of fouling, make metal pipe-wall, incrustation scale, water is vibration thereupon simultaneously, but because metal, the inertia of incrustation scale and water is different with elasticity, the frequency response difference, make it to produce between the three asynchronous vibration, long asynchronous vibration, make incrustation scale produce minute crack gradually, after the crack forms, produce capillarity thereupon, make the water nexine that enters incrustation scale along the crack rapidly, after this atomic little water enters the crack of incrustation scale and tube wall, heated by the high temperature tube wall, volume sharply expands, explosion behind the generation bubble, the promotion incrustation scale breaks away from tube wall and comes off.Meanwhile, small current also will be stored at the oxygen of tube surface and take away, and reduce the oxide etch of metal surface, and this will improve the service life of boiler and heat exchanger greatly.Exterior vibration sensor 3 is used to pick up the vibration frequency of magnetostrictive transducer 2, and transducing signal treatment circuit 4 transfers to main frame 1 after this signal is handled.
