Examples

The embodiment of the utility model provides a steam cyclone soot blower which can be mainly applied to boilers of various types in the fields of electric power, metallurgy, building materials, petrochemical industry and the like, and comprises various pulverized coal boilers, circulating fluidized bed boilers, oil-fired boilers, waste heat furnaces, heating furnaces, process furnaces, garbage incinerators and the like. The boiler tail part heat exchanger can be suitable for a plurality of parts of the boiler tail part, including a hearth water-cooled wall, a superheater, a reheater, an economizer, an air preheater, an electric dust remover and the like.

The soot blowing principle of the steam cyclone soot blower provided by the embodiment is that a gas source (compressed air or steam) with certain pressure is input into a special gas chamber of the soot blower, so that the gas source generates oscillation in a specific geometric cavity, and the gas in the cavity is excited to strongly oscillate to generate high-strength cyclone. The ash-removing mechanism is that high-strength rotational flow is sent into various space regions which are possibly deposited with ash and slag in a boiler body in operation, and the air and dust particles in the regions are oscillated under the action of air agitation energy to destroy and prevent the combination of the dust particles on the heat exchange surface or among the particles, so that the dust particles are always in a suspension fluidization state, and the dust particles are conveniently taken away by smoke or gravity.

The coal dust used as fuel of the boiler generally has higher sulfur content, so that dust particles are accumulated and sintered to form coke residue and ash. After the rotational flow acts on the coke slag deposition, the vibration displacement generated by the rotational flow energy is large and the speed is high, so that dust cannot be accumulated, and the growth of the coke slag is prevented. Meanwhile, due to the fatigue effect of the high-strength rotational flow, the formed large coke slag can be broken, so that the binding force among coke slag particles is weakened, the gap is increased, the growth speed is slowed down, the volume of the slag block is reduced, and the slag block is easy to fall off automatically.

The cyclone dust-removing and gas (steam) force, hydraulic power and the method for cleaning dust by rapping a drop ball belong to pure physical mechanisms, but the energy of the cyclone dust-cleaning action comes from high-strength cyclone which is a mechanical wave existing in the form of energy and is represented by vibration, disturbance and fluctuation, and the violent and fast-changing vibration of the high-strength cyclone causes the separation, fatigue fracture and breakage of deposited dust and coke in the adhesion state of a heated surface. In the industry, the high-intensity swirling flow for ash removal is that air or (steam) is used as a power source, and the energy of the air or (steam) is converted into the high-intensity swirling flow by a special swirling flow generator.

As shown in fig. 1 and 2, comprises a body including a gas inlet 1, a cavity 2, an adjusting connector 3, a first vibrating plate 4, a second vibrating plate 5; the first vibrating piece 4 is arranged on the main body through an adjusting connector 3, the adjusting connector 3 is used for adjusting the contact area of the first vibrating piece 4 and the main body, and the second vibrating piece 5 is positioned on the outer side of the first vibrating piece 4; an air source enters the main body through the air inlet 1, and after passing through the joint of the second vibrating piece 5 and the main body, the air source enters the cavity 2 to oscillate and then triggers the first vibrating piece 4 and the second vibrating piece 5 to oscillate to emit sound waves.

The first membrane 4 is not in direct contact with the second membrane 5. The first membrane 4 is arranged parallel to the body. The first vibrating reed 4 has a structure in which one end is thick and the other end is thin. Thus, the vibrating pieces are different in thickness, and oscillation waves having different intensities and amplitudes can be generated during oscillation. In this embodiment, the thin end of the first vibrating piece 4 is connected to the adjusting connector 3, or the thick end of the first vibrating piece 4 may be connected to the adjusting connector 3

A drain valve is arranged in the cavity 2 and used for discharging liquid water after steam condensation. Thus, when the soot blowing is suspended or finished, the drain valve can be opened to drain the liquid water after the steam is condensed.

The second vibrating reed 5 is bent from the inside to the outside with respect to the main body. The thickness of the connection of the second membrane 5 to the body is the thickest part of the second membrane 5. The curvature of the second membrane 5 increases gradually. The first vibrating piece 4 and the second vibrating piece 5 are arranged at the rear part and the front part of the cavity 2 respectively and are in different shapes and thicknesses, so that vibrating waves with different intensities and amplitudes are generated, the vibrating waves generated by different vibrating pieces or different parts of the same vibrating piece can strengthen the intensity of the vibrating waves when resonance occurs, and thus, the formed large coke slag can also break, the binding force between coke slag particles is weakened, the gap is increased, the growth speed is slowed down, the volume of the slag blocks is reduced, and the slag blocks are easy to fall off by oneself.

Furthermore, the intensity and amplitude of the oscillation of the first membrane 4 can be adjusted by adjusting the adjusting connections 3 to increase or decrease the contact surface of the first membrane 4 with the body, depending on the actual production needs.

Compared with the prior art, the steam cyclone soot blower has the advantages that one or more first vibrating reeds and one or more second vibrating reeds are arranged, the contact surface of the first vibrating reeds and the main body is adjusted through the adjusting connecting piece, and a gas source (compressed air or steam) with certain pressure is input into the specially-made gas chamber of the soot blower, so that the gas source generates oscillation in a specific geometric cavity, and strong oscillation of gas in the cavity is excited to generate high-strength cyclone. The vibrating reeds with different structures generate the same or/and different oscillation waves, the oscillation waves with higher strength can be generated by superposition, and then the formed large coke slag can be broken, so that the binding force among coke slag particles is weakened, the gap is increased, the growth speed is slowed down, the volume of the slag blocks is reduced, and the large coke slag is easy to fall off automatically.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
