Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically a variable frequency high-efficiency electric frequency modulation acoustic cleaning device. Background Technology

[0002] During boiler operation, ash and slag buildup on the heating surfaces—water-cooled walls, superheaters, economizers, preheaters, and flues—is a long-standing and difficult-to-solve problem. It not only weakens heat transfer on the boiler's heating surfaces, reducing boiler thermal efficiency and production load, but also, when ash and slag buildup on the heating surfaces is severe, can lead to unexpected shutdowns and significant economic losses.

[0003] Currently, most boilers are equipped with steam soot blowers, compressed air soot blowers, and steel ball soot blowers. However, these traditional soot blowers have drawbacks in operation and performance, such as limited blowing range, blind spots, high energy consumption, high maintenance costs, inconvenient operation, and side effects. Their utilization rate is very low, and most are left unused. Therefore, new technologies must be sought to remove ash from boiler heating surfaces and prevent slagging. Utility Model Content

[0004] The present invention aims to solve the above problems and thus provide a variable frequency high-efficiency electric frequency modulation acoustic cleaning device.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] A variable frequency high-efficiency electric frequency modulation acoustic cleaning device includes an inlet valve, a pressure stabilizing tank, a variable frequency motor, a conversion chamber, a cleaning outlet valve, and an acoustic waveguide.

[0007] One end of the inlet valve is connected to the air inlet pipe, and the other end is connected to the pressure stabilizing tank to control the air supply.

[0008] The pressure stabilizing tank is connected to the conversion chamber via a flange. The conversion chamber is equipped with a cutting disc with notches around its perimeter, and the cutting disc is placed horizontally.

[0009] The upper part of the conversion chamber is connected to the variable frequency motor via a connecting shaft. When the variable frequency motor rotates, it drives the connecting shaft to rotate, thereby causing the cutting disc inside the conversion chamber to rotate and cut the airflow to generate sound waves.

[0010] The side of the conversion chamber is connected to the dust removal outlet valve via a flange, and the dust removal outlet valve controls the on / off of the acoustic waves.

[0011] The outlet end of the ash removal outlet valve is connected to the acoustic waveguide, the end of which is horn-shaped to amplify the sound waves.

[0012] Furthermore, a pressure gauge is installed on the pipeline between the pressure stabilizing tank and the inlet valve to monitor the pressure inside the pressure stabilizing tank.

[0013] Furthermore, the inlet valve is a solenoid valve; the air intake of the device is controlled by switching the inlet valve on and off.

[0014] Furthermore, the ash removal outlet valve is an electric ball valve; the on / off state of the sound wave is controlled by switching the outlet valve on and off.

[0015] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0016] This invention uses a variable frequency motor to drive the cutting disc inside the conversion chamber to rotate. The cutting disc cuts the airflow and generates sound waves that act on the ash layer, causing the ash layer to separate and break down. Under the combined action of gravity and wind, the ash layer is removed, thus achieving the purpose of cleaning. Sound wave cleaning does not require contact with the ash surface, reducing energy loss and equipment wear, making it highly efficient and energy-saving. Attached Figure Description

[0022] One end of the inlet valve 1 is connected to the air inlet pipe, and the other end is connected to the pressure stabilizing tank 2 to control the air supply.

[0023] The pressure stabilizing tank 2 is connected to the conversion chamber 4 via a flange. The conversion chamber 4 is equipped with a cutting disc 7 with notches 7-1 around its perimeter. The cutting disc 7 is placed horizontally.

[0024] The upper part of the conversion chamber 4 is connected to the frequency converter motor 3 through a connecting shaft. When the frequency converter motor 3 rotates, it drives the connecting shaft to rotate, thereby causing the cutting disc 7 inside the conversion chamber 4 to rotate and cut the airflow to generate sound waves.

[0025] The side of the conversion chamber 4 is connected to the dust removal outlet valve 5 via a flange, and the dust removal outlet valve 5 controls the on / off of the acoustic wave.

[0026] The outlet end of the dust removal outlet valve 5 is connected to the acoustic waveguide 6. The end of the acoustic waveguide 6 is horn-shaped, which amplifies the sound waves. The horn-shaped acoustic waveguide effectively improves the radiation efficiency.

[0027] Furthermore, a pressure gauge is installed on the pipeline between the pressure stabilizing tank 2 and the inlet valve 1 to monitor the pressure inside the pressure stabilizing tank 2.

[0028] Furthermore, the inlet valve 1 is a solenoid valve; the opening and closing of the air intake device is controlled by switching the inlet valve on and off.

[0029] Furthermore, the ash removal outlet valve 5 is an electric ball valve; the on / off state of the sound wave is controlled by switching the ash removal outlet valve 5 on and off.

[0030] This invention uses a variable frequency motor to drive the cutting disc inside the conversion chamber to rotate. The cutting disc cuts the airflow and generates sound waves that act on the ash layer, causing the ash layer to separate and break down. Under the combined action of gravity and wind, the ash layer is removed, thus achieving the purpose of cleaning. Sound wave cleaning does not require contact with the ash surface, reducing energy loss and equipment wear, making it highly efficient and energy-saving.
