Description

Technical Field

[0001] The invention relates to the technical field of sootblowers, in particular to a boiler sootblower seal. Background Art

[0002] Boiler soot blowers are increasingly widely used in various industries. They are mainly used in boilers. They use the energy of the sound field to remove the soot on the boiler heating surface. They are completely different from other soot removal technologies. The WSB series boiler soot blower technology converts compressed air (or steam) into high-power sound waves or infrasound waves (a pressure wave that propagates in the space medium (gas) in the form of a sparse-dense wave) and sends it into the furnace. When the soot on the heating surface is repeatedly pulled and pressed by the sparse-dense wave that changes alternately at a certain frequency, it loosens and falls off due to fatigue and is carried away with the flue gas flow, or sinks to the ash hopper under the action of gravity and is discharged;

[0003] Boiler ash accumulation is one of the important reasons that affect boiler performance. In order to overcome the ash leakage between the sootblower and the furnace body, improve the thermal efficiency of the boiler, and solve the ash leakage between the sootblower and the boiler wall. There is a certain gap between the sootblower passing through the furnace wall hole and the sootblower pipe, causing the furnace to leak hot air outward, affecting the thermal efficiency of the boiler and polluting the external environment.

[0033] Boiler soot blowers are increasingly widely used in various industries. They are mainly used in boilers. They use the energy of the sound field to remove the soot on the boiler heating surface. They are completely different from other soot removal technologies. The WSB series boiler soot blower technology converts compressed air (or steam) into high-power sound waves or infrasound waves (a pressure wave that propagates in the space medium (gas) in the form of a sparse-dense wave) and sends it into the furnace. When the soot on the heating surface is repeatedly pulled and pressed by the sparse-dense wave that changes alternately at a certain frequency, it loosens and falls off due to fatigue and is carried away with the flue gas flow, or sinks to the ash hopper under the action of gravity and is discharged;

[0034] In the related technology, boiler soot accumulation is one of the important reasons affecting boiler performance. In order to overcome the soot leakage between the sootblower and the furnace body, improve the thermal efficiency of the boiler, and solve the soot leakage between the sootblower and the boiler wall, there is a certain gap between the sootblower passing through the furnace wall hole and the sootblower pipe, causing hot air to leak out of the furnace, affecting the thermal efficiency of the boiler and polluting the external environment.

[0035] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a boiler sootblower seal, two sealing plates are arranged on the outside of the sootblower sleeve, and then the mounting plate is connected to the wall to prevent the hot air in the furnace from leaking from the gap between the wall hole and the sleeve, thereby improving the thermal efficiency of the boiler.

[0036] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0037] Combination Figure 1-Figure 3 The embodiment of the present application provides a boiler sootblower seal, which is characterized in that it includes a mounting plate 100 and a tube body 110 arranged on the inner side of the mounting plate 100, a through hole is opened on one side of the mounting plate 100, a sealing plate 1 200 and a sealing plate 2 300 are slidably connected on one side of the mounting plate 100, and a sealing gasket 1 210 is arranged on the inner side walls of the sealing plate 1 200 and the sealing plate 2 300, and the boiler sootblower passes through the through hole, and the sealing plate 1 200 and the sealing plate 2 300 are connected to cover the gap between the boiler sootblower and the through hole.

[0038] Specifically, after the sootblowing pipe of the boiler sootblower passes through the pipe body 110, the two sealing plates are butted together by changing the distance between the two sealing plates. At this time, the sealing gaskets on the two sealing plates are attached to the outer side wall of the sootblowing pipe, thereby reducing the gap therebetween.

[0039] In some embodiments, an adjustment assembly 400 is disposed on one side of the mounting plate 100 , and the adjustment assembly 400 is used to drive the distance between the sealing plate 1 200 and the sealing plate 2 300 .

[0040] Specifically, when adjusting the distance between the two sealing plates, the distance between the two sealing plates can be adjusted simultaneously by adjusting the assembly 400, so as to quickly connect with the sootblowing pipe.

[0041] In some embodiments, the adjustment assembly 400 includes a bearing seat 410, and the bearing seat 410 is symmetrically arranged on one side of the mounting plate 100. The bearing seat 410 is rotatably connected to a bidirectional screw 420, and the bidirectional screw 420 is threadedly connected to the sealing plate 200 and the sealing plate 300 respectively.

[0042] Specifically, the operator rotates the bidirectional screw 420, which rotates on the bearing seat 410. At this time, the two sealing plates move toward each other or in opposite directions on the bidirectional screw 420, thereby reducing the difficulty of operation and quickly connecting the two sealing plates to the blowpipe.

[0043] In some embodiments, a limiting assembly 700 is provided on one side of the mounting plate 100, and the limiting assembly 700 includes a bearing seat 2 710. The bearing seat 2 710 is symmetrically provided on one side of the mounting plate 100, and a sliding rod 720 is provided between the two bearing seats 2 710. The sliding rod 720 passes through the sealing plate 1 200 and the sealing plate 2 300.

[0044] Specifically, when the two sealing plates move, the movement positions of the two sealing plates are limited by the setting of the sliding rod 720 .

[0045] In some embodiments, a shielding assembly 600 is provided on one side of the mounting plate 100, and a gear 430 is provided on the outer wall of the bidirectional screw 420. When the sealing plate 1 200 and the sealing plate 2 300 move toward opposite sides, the gear 430 drives the shielding assembly 600 to move downward to shield the through hole.

[0046] Specifically, after the sootblowing of the boiler is completed, the sootblowing pipe is led out from the pipe body 110. At this time, the operator can reversely rotate the bidirectional screw 420 so that the gear 430 of the bidirectional screw 420 drives the shielding assembly 600 to move, thereby shielding the through hole opened in the wall.

[0047] In some embodiments, the shielding assembly 600 includes a track 610, and the track 610 is symmetrically arranged on one side of the mounting plate 100. A baffle 620 is slidably connected to the inner side of the track 610. A rack 621 is arranged on one side of the baffle 620, and the rack 621 is meshed with the gear 430. A roller 500 is arranged on one side of the mounting plate 100.

[0048] Specifically, when the gear 430 rotates, it meshes with the rack 621 and drives the entire baffle 620 to slide on the track 610 , and finally the baffle 620 moves to the bottom plate 630 and stops. The bottom plate 630 is arranged on one side of the mounting plate 100 .

[0049] In some embodiments, a roller 500 is disposed on one side of both sealing plate 1 200 and sealing plate 2 300 ; a protrusion is disposed on one side of sealing plate 1 200 , and a groove matching the protrusion is disposed on one side of sealing plate 2 300 .

[0050] Specifically, the setting of the two rollers 500 can limit the rotation of the soot blowing pipe. The two rollers 500 do not move accordingly when the two sealing plates move, so that it is easy to adjust the two rollers 500 and to facilitate the extraction of the soot blowing pipe. The protrusions and grooves mentioned above are not reflected in the accompanying drawings, and the docking of the two facilitates the docking of the two sealing plates.

[0051] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0052] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
