Description
Technical field
The present invention relates to a kind of device of the water pollutant that is used to degrade, particularly a kind of ultrasonic wave transducer device of handling pollutant.
Background technology
In wastewater treatment, extensively utilize organism in the ultrasonic transducer degrading waste water at present.Its principle of work is to produce high-frequency oscillation signal by oscillatory circuit, produce 20～40KHz ultrasound wave by transducer, excite water generates a large amount of-the OH free radical, by hyperacoustic cavitation effect the organism in the sewage is carried out oxidation, thus the organism in the degrading waste water.
For example, a kind of ultrasonic transducer is disclosed among the CN1583587A, this ultrasonic transducer comprises a piezoelectric ceramic piece, be placed in pending waste water bottom, the ultrasonic waves transmitted energy in order to improve is so that improve the efficient of handling waste water, therefore often need settle a plurality of such ultrasonic transducers in the bottom of pending waste water, not only mounting structure is complicated, and the bottom that is placed in treatment sewage owing to the ultrasonic wave transducer device has reduced the work efficiency of ultrasonic transducer.
Summary of the invention
The objective of the invention is to overcome weak point noted earlier, a kind of ultrasonic wave transducer device is provided.
For realizing the object of the invention, provide following technical scheme:
A kind of ultrasonic wave transducer device comprises: overcoat is tubular; Vertically replace stacked conducting strip and piezoelectric vibrator along overcoat, be encapsulated in the overcoat.
Wherein, the both sides that replace stacked conducting strip and piezoelectric vibrator are respectively equipped with the conductor wire that is connected with pulsed high voltage generator.Piezoelectric vibrator is a piezoelectric ceramic piece.
In addition, also comprise: the interior cover between overcoat and piezoelectric vibrator, be tubular, its outside surface is consistent with the inner surface configuration of overcoat, its inside surface is consistent with the outside surface of conducting strip and piezoelectric vibrator, so that make between overcoat and the interior cover and interior cover closely contacts with replacing to form between stacked conducting strip and the piezoelectric vibrator.Particularly, interior cover is combined by at least two branch covers, settles conductor wire in the gap between minute cover.
One in a side in each conducting strip both sides and two leads contacts, and another root in its opposite side and two leads is isolated.
Particularly, overcoat and interior cover are cylindrical.
Compared with the prior art the present invention has the following advantages:
Ultrasonic wave transducer apparatus structure of the present utility model is simple, compact, reasonable, energy consumption is low and conversion efficiency is high, can be placed in pending water middle part, the area that contacts with water is big, make the ultrasonic energy of generation directly act on treatment sewage and produce a large amount of OH ions, the speed of disposing of sewage is fast.

Embodiment
As shown in Figure 1, ultrasonic wave transducer device of the present utility model comprises cylinder-shaped coat 31, is placed in the interior interior cover 32 of cylinder-shaped coat, alternately is stacked in metallic conduction sheet 34 and piezoelectric ceramic piece 35 in the interior cover 32 from top to bottom.The external cylindrical surface of piezoelectric ceramic piece 35 closely contacts with the inner periphery of interior cover 32, and the outer cylinder surface of interior cover 32 closely contacts with the inner periphery of overcoat.
As shown in Figure 2, each piezoelectric ceramic piece 35 forms electrode by its two neighbouring conducting strips 34, left side (second side) connected with a left side (second) lead 33b if conducting strip 34 right sides (first side) of its top isolate with right (first) lead 33a, then the conducting strip right side (first side) of its below is connected with right (first) lead 33a, and its left side (second side) isolates with a left side (second) lead 33b, and promptly adjacent conductive sheet 34 alternately connects two leads 33 of both sides.
Wherein overcoat 31 is made of the Titanium alloy of chromium plating.For the ease of assembling, interior cover 32 is divided into two semicylindrical branch cover 32a, 32b (also can be divided into plural branch cover), settle two lead 33a, 33b (seeing shown in Figure 2) between two minutes covers 32a, the 32b, connect pulsed high voltage generator 19 respectively.
Ultrasonic wave transducer device 16 can vertically be placed in the middle part of the water tank that fills pending waste water, be applied on the column type ultrasonic wave transducer device 16 by pulsed high voltage generator 19 output HIGH voltages (about peak value 2500V), stacked from top to bottom a plurality of piezoelectric ceramic pieces 35 just produce the horizontal direction ultrasound wave of radially outward launching along the whole face of cylinder of 20～40KHz in the column type ultrasonic unit, act on the waste water of handling in the water tank, induce wherein O by hyperacoustic cavitation effect
3Produce a large amount of-OH free radical with hydrogen peroxide, organism generation oxidation reaction in-OH free radical and the water, thereby the organism that dissolves in the oxidized waste water acts on the waste water micro air bubble simultaneously by hyperacoustic high-temperature effect and cavitation effect, quickens waste water degraded and oxidation.
