Description

Technical Field

[0001] The utility model relates to a sonic soot blowing device, in particular to a soot blowing device used for a regenerative incinerator. Background Art

[0002] The existing sonic soot blower uses compressed air as its power source. The diaphragm vibrates in the resonance cavity of the sonic energy device to generate specific low-frequency, high-energy sound waves. These sound waves diffuse into the incinerator through the sound amplifier and act on the ash deposited on the surface of the ash-forming object, causing it to produce sound-induced fatigue and peel off, thereby achieving the purpose of removing the ash deposits.

[0003] After the traditional sonic soot blower is used in the incinerator, it has a certain ash removal effect. However, in the subsequent maintenance and inspection of the incinerator, it was found that some corners inside the incinerator and the inner wall away from the mouth of the loudspeaker had some ash remaining. Subsequent analysis found that the ash remaining in these parts was caused by the long propagation path of the sound wave. It is difficult for the sound wave to directly act on the above-mentioned positions after being emitted by the loudspeaker. It can only be propagated to the above-mentioned points after continuous reflection and refraction. However, the sound waves propagated to the above-mentioned points will have energy attenuation after long-distance propagation, which will cause the ash accumulation in these areas to be unable to be effectively removed. Moreover, the loudspeaker in the traditional sonic soot blower is fixedly connected to the inner wall of the incinerator, which makes it impossible to adjust the initial propagation path of the sound wave emitted by the acoustic energy device, resulting in the inability to improve the ash accumulation in the corners inside the incinerator and the inner wall away from the mouth of the loudspeaker. Therefore, it is necessary to propose a sonic soot blower with adjustable sound wave direction. Utility Model Content

DETAILED DESCRIPTION

[0032] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description created by the present application, unless otherwise specified, "multiple" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0035] The technical solution of the present application is designed based on a sonic soot blower applied to an incinerator 1. The existing sonic soot blower uses compressed air as a power source. The diaphragm vibrates in the resonance cavity of the acoustic energy device 3 to generate specific low-frequency, high-energy sound waves. These sound waves diffuse into the incinerator 1 through the loudspeaker, act on the ash accumulated on the surface of the ash-forming object, causing it to produce acoustic fatigue and peel off, thereby achieving the purpose of removing the ash accumulation. After the traditional sonic soot blower is used in the incinerator 1, it has a certain ash removal effect. However, during the subsequent maintenance and inspection of the incinerator 1, it was found that some corners inside the incinerator 1 and the inner wall away from the mouth of the loudspeaker had some ash remaining. Subsequent analysis found that the ash remaining in these parts was caused by the long propagation path of the sound wave. It is difficult for the sound wave to directly act on the above-mentioned positions after being emitted by the loudspeaker. It can only be propagated to the above-mentioned points after continuous reflection and refraction. However, the sound waves propagated to the above-mentioned points will experience energy attenuation after long-distance propagation, which will cause the ash accumulation in these areas to be unable to be effectively removed. The loudspeaker in the traditional sonic soot blower is fixedly connected to the inner wall of the incinerator 1, which makes it impossible to adjust the initial propagation path of the sound wave emitted by the acoustic energy device 3, resulting in the inability to improve the ash accumulation in the corners inside the incinerator 1 and the inner wall away from the mouth of the loudspeaker. Therefore, the applicant proposed a solution for the embodiment of the utility model.

[0036] See also Figure 1 and Figure 2The present embodiment provides a sootblowing device for a regenerative incinerator 1, comprising a first megaphone 2, an acoustic energy device 3, a first gas pipeline 6, a second megaphone 4 and a driving mechanism 5. The first megaphone 2 is arranged on the inner wall of the incinerator 1, and the mouth of the first megaphone 2 faces the inner space of the incinerator 1. The acoustic energy device 3 can emit sound waves for sootblowing. The acoustic energy device 3 is arranged in the first megaphone 2 so that the initial propagation path of the sound wave is in the same direction as the mouth of the first megaphone 2, so as to transmit the sound wave to the inner wall of the incinerator 1. The first gas pipeline 6 is connected to the acoustic energy device 3 to pass compressed air into the acoustic energy device 3. The second megaphone 4 is arranged on the first megaphone 2. At the mouth of the tube, the connection between the second megaphone 4 and the first megaphone 2 is sealed, and the posture of the second megaphone 4 is configured to be adjustable relative to the first megaphone 2, so that the direction of the mouth of the second megaphone 4 and the direction of the mouth of the first megaphone 2 may have an angle, and the driving mechanism 5 is connected to the second megaphone 4 to adjust the posture of the second megaphone 4, thereby changing the direction and size of the angle between the mouth of the second megaphone 4 and the mouth of the first megaphone 2. In this embodiment, the direction of the mouth of the second megaphone 4 can be adjusted by the driving mechanism 5, thereby changing the initial propagation path of the sound waves emitted by the acoustic energy device 3, so as to shorten the distance of the sound waves transmitted to the target position, thereby ensuring that the sound waves emitted by the sonic soot blower have a good cleaning effect on the ash accumulation at the target position in the incinerator 1. It should be noted that the target position in the foregoing specifically refers to the corner of the internal part of the incinerator 1 and the inner wall away from the direction of the mouth of the megaphone.

[0037] Specifically, in this embodiment, the first megaphone 2 has a first end face 210 and a second end face 220 arranged in parallel, the contour shape of the first end face 210 and the contour shape of the second end face 220 are both concentric circles, the first end face 210 extends to the second end face 220 along its normal direction to form the first megaphone 2, the second end face 220 is the mouth end of the first megaphone 2, and the first end face 210 is sealed and connected to the gas pipeline. It should be noted that, in this embodiment, the diameter of the concentric circle corresponding to the first end face 210 is the same as the diameter of the concentric circle corresponding to the second end face 220. The second megaphone 4 has a third end face 410 and a fourth end face 420 arranged in parallel, the contours of the third end face 410 and the fourth end face 420 are both concentric circles, the third end face 410 extends along its normal direction to the fourth end face 420 to form the second megaphone 4, the fourth end face 420 is the tube mouth end of the second megaphone 4, and the third end face 410 is connected to the tube mouth of the first megaphone 2. It should be noted that in this embodiment, the diameter of the concentric circle corresponding to the fourth end face 420 is greater than the diameter of the concentric circle corresponding to the third end face 410, so that the shape of the second megaphone 4 is horn-shaped, and the horn mouth of the second megaphone 4 is diffused in the direction from the third end face 410 to the fourth end face 420.

[0038] Please also read Figure 3-4 In this embodiment, a spherical protrusion 230 is constructed on the outer periphery of the first loudspeaker 2 near the second end surface 220, and the center of the spherical protrusion 230 is located on the axis of the first loudspeaker 2. A spherical groove 430 adapted to the spherical protrusion 230 is constructed on the inner periphery of the second loudspeaker 4 near the third end surface 410, and the center of the spherical groove 430 is located on the axis of the second loudspeaker 4. The spherical protrusion 230 is confined in the spherical groove 430 in a movable connection manner, and the center of the spherical protrusion 230 coincides with the center of the spherical groove 430, so as to confine the second loudspeaker 4 to move around the center of the spherical protrusion 230.

[0039] Specifically, in this embodiment, the diameter corresponding to the spherical protrusion 230 is equal to the diameter corresponding to the spherical groove 430, and when the spherical protrusion 230 is embedded in the spherical groove 430, it is difficult for the spherical protrusion 230 to be separated from the spherical groove 430 due to the structural dimensions of the spherical groove 430 and the second megaphone 4, so that the second megaphone 4 can only rotate around the center of the spherical protrusion 230, thereby adjusting the direction of the tube mouth of the second megaphone 4. It should be noted that the angle and direction of the second megaphone 4 relative to the first megaphone 2 are limited by the specific dimensions of the spherical protrusion 230 and the spherical groove 430.

[0040] In the present embodiment, the outer peripheral side profile of the second loudspeaker 4 is approximately a truncated cone, and the second loudspeaker 4 has a hypotenuse (not shown in the figure) when observed along the cross section through its axis, and the hypotenuse corresponds to the inclined surface on the circumferential side of the truncated cone. The driving mechanism 5 includes a first pipe fitting 510, a lifting rod 520, and a second gas pipeline (not shown in the figure). The first pipe fitting 510 is fixedly installed on the side wall of the incinerator 1 in a plug-in manner, and the connection between the circumference of the first pipe fitting 510 and the side of the incinerator 1 is sealed by welding and connected as a whole. At this time, one end of the first pipe fitting 510 is located outside the incinerator 1, and the other end is located inside the incinerator 1 (only the main body of the furnace body is shown in the figure). The lifting rod 520 is movably inserted into the first pipe fitting 510, and one end of the lifting rod 520 is confined in the first pipe fitting 510, and the other end of the lifting rod 520 is a free end, which is connected through the first One end of the pipe fitting 510 located in the incinerator 1 extends into the incinerator 1, and a pulley 530 is also provided at one end of the lifting rod 520 located in the incinerator 1. The pulley 530 is restricted to rotate in this section of the lifting rod 520, and the circumference of the pulley 530 abuts against the inclined surface. The second gas pipeline is provided outside the incinerator 1, and the second gas pipeline is connected to one end of the first pipe fitting 510 located outside the incinerator 1 to pass gas into the first pipe fitting 510, so that the lifting rod 520 moves relative to the first pipe fitting 510. When one end of the lifting rod 520 extends out of the first pipe fitting 510, the circumference of the pulley 530 squeezes the inclined surface of the second megaphone 4, so that the second megaphone 4 deflects around the center of the circle in a direction away from the pulley 530, thereby changing the initial propagation path of the sound wave. It should be noted that a piston 540 is disposed at one end of the lifting rod 520 in the first tube 510 , and the circumference of the piston 540 is in contact with the inner wall of the first tube 510 .

[0041] See also Figure 3In this embodiment, there are twelve first pipes 510, which are arranged in an equidistant array around the axis of the first megaphone 2, and each first pipe 510 is equipped with a lifting rod 520, and each lifting rod 520 is installed with a pulley 530 at one end located in the incinerator 1, and the circumference of these pulleys 530 is in contact with the inclined surface of the circumference of the second megaphone 4. Each first pipe 510 is connected with a separate second gas pipeline, and each second gas pipeline can be supplied with gas separately, so that the lifting rod 520 in each first pipe 510 can be extended separately. It should be noted that each first pipe fitting 510 is also provided with an air release valve (not shown in the figure) to facilitate the discharge of gas in the first pipe fitting 510 so that the lifting rod 520 can move back. At this time, the return of the lifting rod 520 mainly depends on the automatic return of the second loudspeaker 4 under the influence of gravity. After the gas in the first pipe fitting 510 is emptied, the second loudspeaker 4 rotates around the center of the circle under the action of gravity, and the inclined surface on its circumferential side will lift the lifting rod 520, so that the lifting rod 520 will retract into the first pipe fitting 510.

[0042] Please also read Figure 5 In an optional embodiment, after the lifting rod 520 extends from the first pipe fitting 510, in order to assist the lifting rod 520 in moving back, a spring 550 can be sleeved on the circumferential side of the lifting rod 520, and an annular flange 511 is constructed on the inner wall of the first pipe fitting 510 in a direction perpendicular to its own axis, so that one end of the spring 550 abuts against the annular flange 511, and the other end of the spring 550 abuts against one end of the piston member 540, so that after the pressure relief valve discharges the gas in the first pipe fitting 510, the spring 550 provides the lifting rod 520 with a force pointing in the direction of the inner wall of the incinerator 1, so that the lifting rod 520 moves back.
