Description

Technical Field

[0002] The rapping hammers of the elastic rapping ash cleaners or mechanical rapping ash cleaners on the market are all external. The rapping hammers are driven by the power mechanism to hit the connecting rod, and then the force is transmitted to the convection hot surface of the boiler through the connecting rod. The rapping device is large in size, poor in sealing, and has high requirements for the surrounding space. The rapping force is adjusted by the motor. The multiple rapping points of the entire hot surface are connected by connecting rods. The force rapped on the hot surface is difficult to estimate, the hot surface is unevenly stressed, and the rapping force cannot be adjusted locally according to the different dust accumulation conditions of the tube bundle. In order to ensure the cleaning effect, the rapping force can only be increased, which is easy to damage the hot surface locally.

[0003] Due to poor sealing, when the boiler is running at positive pressure, flue gas leaks out, causing corrosion to peripheral equipment. When the boiler is running at negative pressure, cold air is sucked into the boiler, the flue gas temperature around the leakage point is low, and the flue gas condenses, causing corrosion to the rapping rod and hot surface.

[0033] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 As shown, the embodiment of the present application provides a fully sealed built-in electromagnetic elastic vibration cleaning device, including a cleaning device body 001, and the cleaning device body 001 includes:

[0036] A rapping mechanism 100, wherein the rapping mechanism 100 comprises a rapping rod 110 and a high temperature resistant electromagnet 120;

[0037] The sealing mechanism 200 includes a sealing housing 210, a first sealing steel plate 220, a second sealing steel plate 230, and a graphite sealing filler 240;

[0038] The outer insulation layer 300 is coated on the outside of the dust removal device body 001;

[0039] The rapping rod 110 passes through the sealing mechanism 200 .

[0040] The rapping rod 110 is controlled by the high temperature resistant electromagnet 120 to perform rapping, so as to achieve rapping and cleaning of the boiler convection heat surface, and improve the heat exchange effect of the boiler convection heat surface. The sealing mechanism 200 adopts double-layer sealing, and the inner layer of the graphite sealing filler 240 is hard graphite, which plays a role of lubrication and sealing. The outer layer is installed and connected to form a sealed chamber through the sealing cover 210, the first sealing steel plate 220, and the second sealing steel plate 230. The sealing cover 210, the first sealing steel plate 220, and the second sealing steel plate 230 are all made of corrosion-resistant stainless steel. The corrosion-resistant 316L stainless steel material is used to achieve a complete seal, ensuring that the flue gas does not leak out and the air does not leak in, thus ensuring the operating environment of the boiler. The outer insulation layer 300 can keep the inside of the equipment dry, avoiding condensation inside and outside the equipment, thereby avoiding equipment corrosion, helping to extend the life of the equipment, and helping to optimize the boiler operating environment. The vibration rod 110 is made of heat-resistant steel, and the cleaning device body 001 is welded to the wall panel. The cleaning device body 001 is suitable for high-temperature corrosive flue gas environments and can be used under temperature conditions ≤650℃.
