Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soot blowing, in particular to a boiler steam soot blowing device. Background Art
[0002] During the operation of a boiler, a large amount of ash is generated after fuel combustion. Part of this ash remains in the furnace and is discharged in the form of slag, while the other part enters the tail of the boiler together with the high-temperature gas flow. When the ash-laden flue gas flow passes through the heat exchange surface at the tail of the boiler, some ash particles will deposit on the heat exchange surface to form ash fouling. Since the thermal conductivity of ash is small, once ash fouling occurs on the convective heat exchange surface, the heat transfer of the boiler heating surface will be weakened, the thermal resistance of the heating surface will increase, and thus the heat exchange efficiency of the boiler will be reduced. When the ash fouling and slagging on the heating surface are serious, it may even lead to an accidental boiler shutdown, causing significant economic losses.
[0003] However, in the prior art, during the operation of the soot blowing device, ash fouling easily enters the soot blowing pipeline through the soot blowing port, causing a large amount of ash fouling to adhere to the inner wall of the soot blowing pipeline, which is difficult to clean. Moreover, during the process of transporting the soot blowing medium in the soot blowing pipeline, if the temperature difference with the outside is too large, water droplets will be generated inside the soot blowing pipeline.

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a boiler steam soot blowing device is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A boiler steam soot blowing device includes a steam box. One end of the steam box is connected with a soot blowing pipe through a thread, and a cleaning port is arranged at the other end of the steam box. The top outer wall of the steam box is connected with a steam inlet pipe through a thread, and an installation hole is opened on the top outer wall of the soot blowing pipe. A fixing plate is fixed in the installation hole through a bolt, and a sliding cleaning mechanism is arranged inside the fixing plate.
[0007] As a further scheme of the utility model: The sliding cleaning mechanism includes a slider, a sliding groove, a cleaning ring, a discharge plate, a handle and a sliding plate. The sliding groove is opened at the top of the fixing plate, and the slider is slidably connected in the sliding groove.
[0008] As a further scheme of the utility model: The sliding plate is connected to the bottom of the slider through a bolt, and the cleaning ring is bonded to both sides of the bottom of the sliding plate.
[0009] As a further scheme of the utility model: A discharge port is opened on the bottom outer wall of the soot blowing pipe, and the discharge plate is connected to one side of the discharge port through a hinge.
[0010] As a further scheme of the utility model: The handle is welded to the bottom of the discharge plate.
[0011] As a further solution of the present utility model: the circumferential outer wall of the cleaning ring is provided with bristles distributed at equal intervals.
[0012] As a further solution of the present utility model: a sponge ring is adhesively bonded to the outer circumference of the cleaning ring.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0022] A boiler steam soot blowing device, as Figure 1, Figure 2 and Figure 3 As shown, it includes a steam box 2. One end of the steam box 2 is threadedly connected with a soot blowing pipe 1, and the other end of the steam box 2 is provided with a cleaning port 3. The outer wall of the top of the steam box 2 is threadedly connected with a steam inlet pipe 4. An installation hole is opened on the outer wall of the top of the soot blowing pipe 1, and a fixing plate 5 is fixed in the installation hole by bolts. A sliding cleaning mechanism is arranged in the fixing plate 5.
[0023] To solve the problem of ash accumulation at the nozzle of the soot blowing pipe 1, as Figure 1 and Figure 2 shown, the sliding cleaning mechanism includes a slider 6, a chute 7, a cleaning ring 8, a discharge plate 9, a handle 10 and a sliding plate 11. The chute 7 is opened on the top of the fixing plate 5. The slider 6 is slidably connected in the chute 7. The sliding plate 11 is bolted to the bottom of the slider 6. The cleaning ring 8 is bonded to both sides of the bottom of the sliding plate 11. A discharge port is opened on the outer wall of the bottom of the soot blowing pipe 1. The discharge plate 9 is hinged to one side of the discharge port. The handle 10 is welded to the bottom of the discharge plate 9;
[0024] When ash accumulates at the nozzle of the soot blowing pipe 1, the slider 6 can be pushed back and forth. The slider 6 slides in the chute 7 in the fixing plate 5. At the same time, the slider 6 drives the cleaning ring 8 below the sliding plate 11 at its bottom to clean the inner wall of the nozzle of the soot blowing pipe 1. Thus, the problem that it is difficult to clean the ash accumulated at the nozzle of the soot blowing pipe 1 during the operation of the existing soot blowing device is solved, and the quality of boiler steam soot blowing is improved.
[0025] To solve the problem of water droplets appearing inside the soot blowing pipe 1, as Figure 3 shown, equidistantly distributed bristles 12 are arranged on the circumferential outer wall of the cleaning ring 8, and a sponge ring 13 is bonded to the outer circumference of the cleaning ring 8; Through the arrangement of the bristles 12 and the sponge ring 13, the cleaning work of the soot blowing nozzle is realized, and the problem of water droplets appearing inside the nozzle of the soot blowing pipe 1 due to temperature difference is solved.
[0026] Working principle: When ash accumulates at the nozzle of the soot blowing pipe 1, the slider 6 can be pushed back and forth. The slider 6 slides in the chute 7 in the fixing plate 5. At the same time, the slider 6 drives the bristles on the surface of the cleaning ring 8 below the sliding plate 11 at its bottom to clean the inner wall of the nozzle of the soot blowing pipe 1. At the same time, the sponge ring 13 wrapped around the outer circumference of the cleaning ring 8 can adsorb the water droplets that appear at the nozzle of the soot blowing pipe 1 due to temperature difference. Thus, the problem that it is difficult to clean the ash accumulated at the nozzle of the soot blowing pipe 1 during the operation of the existing soot blowing device is solved.
