[0014] Compared with the prior art, the utility model has the following beneficial effects: the ultrasonic online descaling device is provided with a vibrator assembly, a front-rear adjustment mechanism, a stroke control mechanism, a movable electric push rod and a translation mechanism. For the case of scaling on the inner wall of the pipe, there are three methods for descaling: the first method is to insert the first vibrator into the pipe body, and the first vibrator makes axial reciprocating motion, thereby forming an ultrasonic field in the medium on the inner wall of the pipe body. At this time, the electric push rod can be controlled and adjusted through the control panel to drive the connecting frame to move under the action of the adjusting electric push rod, so that the connecting frame drives the slider to slide along the slide groove, drives the first vibrator to move, and adjusts the length of the first vibrator extending into the pipe body. The size and extension of the first vibrator depend on the pipe diameter and the range of scaling on the inner wall. For common heat exchangers, evaporators and other pipes The gap between the first vibrator and the inner wall of the pipe body is maintained at 1 to 10 times the diameter of the first vibrator. The insertion length is at least 10 mm, and the maximum insertion length can reach the length of the scaling area of the pipe body wall, but in fact it is generally not more than two meters. If the scaling range is very long, it can be inserted from both ends to remove the scale. The specific parameters are determined according to the scaling degree and the characteristics of the scaling layer. In terms of energy input density, it must reach more than three Wh / L, which can be achieved by controlling the processing time through the control panel. There is no obstacle between the first vibrator and the scaling layer to avoid blocking or weakening the ultrasonic field. In this way, the liquid medium stays in the pipe body or flows in it, and the ultrasonic field generated by the first vibrator acts on the pipe wall with the smallest path, breaking the scaling, causing it to fall off and flow out with the medium.
[0015] The second type is to place the second vibrator coaxially near the entrance of the pipe body and can be adjusted by the front and rear adjustment mechanism. The distance from the tip of the second vibrator to the end of the pipe body does not exceed one pipe diameter. The sound wave enters the pipe along the axial direction to form a sound field to act on the inner scaling layer. This setting is used in situations where the length of the pipe section of the pipe body is not more than 5 times the pipe diameter of the pipe body. In this way, the liquid medium stays in the pipe body pipeline or flows in it. The first vibrator is located upstream, and the center of the ultrasonic field is far away from the pipe body wall. The scaling materials are mainly oxidized by hydroxyl radicals formed by the extreme environment in the sound field and washed away with the help of the medium flow.
[0016] The third method is to install the third vibrator in a direction perpendicular to the axis of the pipe body pipeline. The distance from the tip of the third vibrator to the pipe body wall is at least 10 mm and at most about 10 times the pipe diameter. At the same time, the control panel can be operated to control the electric push rod to work. Under the action of controlling the electric push rod, the slide bar is pushed to slide along the slideway, driving the third vibrator to move, thereby expanding the descaling range of the third vibrator. At the same time, the servo motor can be controlled by the control panel to rotate the rotating rod under the action of the servo motor, thereby driving the third vibrator to rotate, thereby expanding the descaling range of the third vibrator. This method also has the function of shell-side descaling. In this method, there is liquid medium inside and outside the pipe body pipeline. The shock wave generated by the ultrasonic field directly hits the outer wall of the pipe body, producing two effects: first, breaking up the scaling layer on the outer wall of the pipe body; second, penetrating through the pipe body wall to reach the scaling object and breaking it.
[0017] The principle of shell-side descaling is also based on the cavitation principle mentioned above. For example, the outer wall of the pipeline, the inner wall of the boiler, etc., the shell-side surface to be descaled is immersed in the medium mother liquor or water, and the ultrasonic wave generates an ultrasonic field in the medium, and the scaling is broken up by cavitation. There are two installation methods for shell-side descaling: The first one: parallel arrangement, used for shell-side descaling of the tube bundle. After the fourth vibrator hits the tube body, the scaling layer on its surface or inside is broken up. Since the tube body has a certain length, in order to ensure the descaling effect, the mobile electric push rod can be controlled to work through the control panel, so that the fourth vibrator can move axially under the action of the mobile electric push rod.
[0018] The second type: vertical arrangement. The function of the fifth vibrator is similar to that of the third vibrator. The translation electric push rod can be controlled through the control panel. Under the action of the translation electric push rod, the slide is driven to move along the guide groove, driving the fifth vibrator to translate and expand the descaling range of the fifth vibrator.
[0019] Online descaling equipment uses the cavitation effect generated by ultrasound in the fluid to remove scale deposits on the container and pipe walls and prevent the formation of new scale layers. It is not easy to cause secondary pollution and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

The power source used is the alternating current of the power grid. Its function is to generate a sinusoidal electrical signal, which is called power. The converter 104 converts the sinusoidal electrical signal into mechanical vibration of the connecting rod. The vibration generates ultrasonic waves in the medium through the vibrator assembly 2. Ultrasonic waves refer to sound waves with a frequency of more than 20 kHz. This frequency band has exceeded the range that the human ear can distinguish. Its characteristic is that it produces a strong cavitation effect. The so-called cavitation effect refers to the continuous compression and expansion of the fluid under the action of the sound field to form countless tiny bubbles. The bubble radius continues to increase and implodes when it reaches a critical value. The implosion generates high temperature (5000 degrees Celsius) and high pressure (500 bar) locally, and ionizes water molecules at the same time to generate strong oxidants-hydroxyl free radicals (OH - ).

[0039] Working principle: When in use, first control the converter 104 through the control panel 101 and the signal generator. The signal generator is an oscillating circuit.

The converter 104 converts the sinusoidal electrical signal into mechanical vibration of the connecting rod. The vibration generates ultrasonic waves in the medium through the vibrator assembly 2.

The size and extension of the first vibrator 201 depend on the diameter of the pipe body 103 and the range of scaling on the inner wall. For common pipe fittings such as heat exchangers and evaporators, the distance between the first vibrator 201 and the inner wall of the pipe body 103 is The gap is maintained at 1 to 10 times the diameter of the first vibrator 201, and the insertion length is at least 10 mm. The maximum insertion length can reach the length of the scaling area of the pipe body 103 wall, but in fact it is generally not more than two meters.

[0041] The second method is to coaxially place the second vibrator 202 near the inlet of the pipe body 103 and adjust it through the front and rear adjustment mechanism 3. The distance from the tip of the second vibrator 202 to the end of the pipe body 103 does not exceed one diameter of the pipe. The sound wave enters the pipe along the axial direction to form a sound field to act on the inner scaling layer. This setting is used in situations where the length of the pipe section of the pipe body 103 is not more than 5 times the diameter of the pipe body 103.

[0042] The third method is to install the third vibrator 203 in a direction perpendicular to the pipeline axis of the tube body 103, with the minimum distance from the tip of the third vibrator 203 to the tube wall of the tube body 103 being 10 mm and the maximum being about 10 times the tube diameter. At the same time, the control panel 101 can be operated to control the electric push rod 402 to work, and the slide bar 4011 is pushed under the action of the control electric push rod 402, so that the slide bar 4011 slides along the slideway 4012, driving the third vibrator 203 to move, thereby expanding the descaling range of the third vibrator 203. At the same time, the control panel can be used to control the electric push rod 402 to control the electric push rod 402 to work. 101 controls the servo motor 4013 to work, and under the action of the servo motor 4013, the rotating rod 4014 is driven to rotate, and the third vibrator 203 is driven to rotate, thereby expanding the descaling range of the third vibrator 203. This method also has the function of shell-side descaling. In this method, there is liquid medium inside and outside the pipe body 103 pipeline. The shock wave generated by the ultrasonic field directly hits the outer wall of the pipe body 103, producing two effects: first, the scaling layer on the outer wall of the pipe body 103 is broken; second, it passes through the pipe wall of the pipe body 103 to reach the scaling object and breaks it.
[0043] The principle of shell-side descaling is also based on the cavitation principle mentioned above. For example, the outer wall of the pipeline, the inner wall of the boiler, etc., the shell-side surface to be descaled is immersed in the medium mother liquor or water, and the ultrasonic wave generates an ultrasonic field in the medium, and the scaling is broken up by cavitation. There are two installation methods for shell-side descaling: The first is parallel arrangement, which is used for shell-side descaling of the tube bundle. After the fourth vibrator 204 hits the tube body 103, the scaling layer on its surface or inside is broken up. Since the tube body 103 has a certain length, in order to ensure the descaling effect, the control panel 101 can be used to control the mobile electric push rod 5 to work, so that the fourth vibrator 204 can move axially under the action of the mobile electric push rod 5.
[0044] The second type: vertical arrangement, the fifth vibrator 205 has a similar function to the third vibrator 203 , and the translation electric push rod 602 can be controlled by the control panel 101 . The translation electric push rod 602 drives the slide 6011 to move along the guide groove 6012 , driving the fifth vibrator 205 to translate, thereby expanding the descaling range of the fifth vibrator 205 .
[0045] The online descaling equipment uses the cavitation effect generated by ultrasound in the fluid to remove scale deposits on the container wall and the pipe wall, and prevent the formation of new scale layers. It is not easy to cause secondary pollution, has low cost, and ultimately completes the use of the online descaling equipment.
[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
