It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0011] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can be practiced in different ways from those described herein, and therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0012] Embodiments

[0013] Please refer to the drawings, in the present application, a novel electromagnetic vibration device for boiler membrane wall ash removal, including electromagnetic vibrator 1, heat insulation filling 2, fixing device 3, membrane wall pipe 4, the electromagnetic vibrator 1 is fixedly connected with fixing device 3;The one end of the electromagnetic vibrator 1 is closely nested in the heat insulation filling 2;The heat insulation filling 2 is arranged in the fixing device 3, new heat insulation filling is arranged mainly around the electromagnetic vibrator 1, on the one hand, the electromagnetic vibrator 1 is protected by heat insulation, prevents the adverse effects of high temperature environment of boiler on its performance and service life;On the other hand, it also helps to transmit and distribute vibration energy to a certain extent, reduces energy loss, to protect the electromagnetic vibrator from high temperature damage;The one end of the electromagnetic vibrator 1 is fixedly connected with the membrane wall pipe 4 through the fixing device 3.

[0014] Further, the fixing device 3 adopts a dispersed stress structure design, which effectively reduces the damage of fatigue stress to the boiler membrane wall pipe, prolongs the service life, and can uniformly transmit the vibration generated by the electromagnetic vibrator 1 to the membrane wall pipe 4, while ensuring the stability of the whole device during the operation of the boiler.

[0015] Further, the connection structure between the electromagnetic vibrator 1 and the fixing device 3 adopts a spring washer plus a common nut plus a slotted nut plus an open pin, the spring washer can provide elastic reaction force after the nut is tightened, to prevent the nut from loosening and causing connection failure during vibration. It can effectively absorb and buffer the vibration energy generated during the operation of the electromagnetic vibrator, reduce the possibility of nut loosening, the common nut first provides preliminary fastening force, tightly connects the electromagnetic vibrator 1 and the fixing device 3 together, and the slotted nut further enhances the reliability of the connection on the basis of the common nut. Its slotted design makes the open pin inserted into the slot of the slotted nut and the hole of the related components after the open pin is installed, forming a loosening prevention mechanism. When the nut has a loosening trend, the open pin will prevent the nut from rotating, so as to ensure that the connection is always firm, effectively preventing the loosening of the fastening device under vibration working condition. To improve the service life of the equipment.

[0016] Use process:

[0017] The electromagnetic vibrator 1 is the core component of the device, generating vibration energy. Through electromagnetic principle, the electrical energy is converted into mechanical vibration energy, providing power source for the whole ash removal process. The vibration action can loosen and fall off the dust and other impurities attached to the membrane wall pipe, so as to achieve the purpose of ash removal. When the current passes through the electromagnet, a magnetic field is generated, which interacts with the vibration component to make the vibration component produce periodic vibration. The frequency and amplitude of the vibration can be adjusted according to actual needs to adapt to different ash removal conditions and the characteristics of the membrane wall pipe; the heat insulation filling mainly plays a heat insulation role. In the boiler operating environment, the temperature is usually high, and the heat insulation filling can reduce the heat transfer to other components such as the electromagnetic vibrator, protect these components from high temperature, and ensure their normal work. At the same time, it can also prevent the ash removal effect from being affected due to excessive heat loss, maintain the device working in an appropriate temperature range, and improve the stability and service life of the device; the fixing device is used to firmly install the electromagnetic vibration device on the membrane wall pipe. In the process of boiler operation, certain vibration and airflow impact will occur, and the fixing device needs to ensure that the electromagnetic vibration device will not be loosened or fallen off due to these external forces, so as to ensure the continuous and stable operation of the ash removal work. At the same time, the reasonable design of the fixing device should also consider the convenience of installation and disassembly, so as to facilitate the operation when the device needs to be repaired or replaced; the membrane wall pipe is an important part of the boiler and the main place where dust is attached. The membrane wall pipe is used to absorb the heat generated by the fuel combustion in the boiler, and transfer the heat to the medium (such as water, steam, etc.) in the pipe. In the process of operation, due to the dust and other impurities contained in the flue gas, they will gradually attach to the surface of the membrane wall pipe, affecting its heat transfer efficiency, so the electromagnetic vibration device is needed to cooperate to realize the ash removal work.

[0018] In the above process, the electromagnetic vibration device for boiler membrane wall ash removal has compact structure, is convenient to install, can realize online automatic ash removal, solves the problem of boiler membrane wall ash deposition, prevents the reduction of boiler thermal efficiency, and can produce good economic benefits; the structure of the present application is simple, practical, and easy to operate, and is worth popularizing.
