Description
Affiliated technical field
The utility model relates to a kind of ultrasonic wave that utilizes industrial pipeline is prevented the device that scale removal is handled, especially than the anti-scale removal device of the ultrasonic wave of long pipeline.
Technical background
For many years, to the antiscaling, descaling of industrial pipeline generally adopt mainly contain three kinds of methods: ion-exchange, chemical method and manual descaling method.Ion-exchange need also need personal management and operation with huge treatment facility, the equipment more complicated, and the operating cost height, and treating capacity is little; Chemical method then needs regular dosing, the cost height, consume big, complex process, and certain pollution is arranged during discharging; Manual scale removal needs to carry out under the situation that equipment is stopped transport, and labour intensity is big, and efficient is low, and may cause mechanical damage to pipeline.
In addition, in recent years the ultrasonic for scale prevention and removal technology that is used for industrial pipeline of Chu Xianing, as Chinese patent CN2183492Y, CN2418967Y, CN2293396Y, CN2173781Y etc., its common trait is: ultrasonic wave is along the pipeline radial emission, utilize ultrasonic wave in fluid cavitation effect and ultrasonic wave in the vibration of tube wall in the hope of realizing the purpose of anti-scale removal.The wretched insufficiency that this class technology exists is: because cavitation effect only occurs in the near zone of ultrasonic transducer and causes the rapid decay of acoustic energy, and the ultrasonic wave that is adopted is along pipeline radiation pattern radially, cause ultrasonic wave to act among a small circle, be difficult to the anti-scale removal effect that reaches desirable; And cavitation can cause the cavitation corrosion of transducer end face and tube wall, equipment effective life weak point.
Summary of the invention
At the deficiency that above-mentioned antiscaling, descaling method exists, the utility model provides a kind of ultrasonic unit that is applicable to the industrial pipeline antiscaling, descaling.The characteristic that this device utilizes ultrasonic wave to propagate in the fluid medium and long distance, acoustic energy is controlled at the scope of cavitation not or weak cavitation, and make its sound wave transmit direction along pipeline axial (consistent) with fluid flow direction, allow ultrasonic wave directly act on the pipe section that needs antiscale away from ultrasonic transducer continuously, utilize the micro slipstream and the flow-disturbing of sound wave, near tube wall, form one deck sound film, reduce the velocity gradient of fluid, stop the generation of dirt and, reach the purpose of comparatively ideal anti-scale removal attached on the tube wall.
The utility model solves its technical problem and is achieved by the following technical solution, and the special cable of the nipple that it is used by ultrasonic wave generation power supply, ultrasonic transducer, installation ultrasonic transducer, connection ultrasonic wave generation power supply and ultrasonic transducer is formed.Wherein, ultrasonic transducer partly is made up of transducer urceolus, preceding transmitting block, back reflection piece, sealing ring and piezoelectric ceramics.Ultrasonic transducer is fixed by welding on the nipple with a hollow pipe, and hollow pipe is also used as the axial vibration stationary pipes simultaneously as wearing the conduit of leading special cable.The nipple part of transducer is installed, and its diameter is big than import and outlet diameter, to reduce the influence to the working fluid fluidised form.The piezoelectric ceramics part is formed by polylith piezoelectric ceramics serial connection, and there is reflex block at its rear portion, and there is transmitting block the front portion, and emitting facet is sphere or plane, and entire portion is loaded in the transducer device urceolus, seals by sealing ring between preceding transmitting block and the urceolus.The polarised direction of piezoelectric ceramics is axial along nipple, transducer and nipple, industrial pipeline coaxial line; By conduit, special cable one end is connected with ultrasonic transducer, and the other end is connected with the output of ultrasonic power; The power work frequency is 20kHz～70kHz, and peak power does not produce cavitation with the transducer emission sound intensity or weak cavitation is a benchmark, and power supply does not adopt pulsed mode and adopts continuous frequency sweep working method.Produce micro slipstream and flow-disturbing by sound wave at the near zone that fluid contacts with inside pipe wall like this, form one deck sound film, reduce the fluid velocity gradient, destroy the zero gradient layer, the prevention dirt generates and attached on the tube wall, plays the effect of antiscale.
Advantage of the present utility model is that sound wave directly acts on the pipeline scale zone along the long propagation of pipeline axial; The power supply of continuously-running duty makes transducer emission continuous sound-field, has strengthened the action effect of sound wave; The control of the power of non-cavitation or weak cavitation has prolonged service life of transducer greatly; The work fluidised form influence of the anti-descaler convection cell of whole ultrasonic ripple is very little.
