Description

Technical Field

[0001] This utility model relates to the technical field of boiler flue deflector soot blowing device, specifically a boiler horizontal flue deflector soot blowing device. Background Technology

[0002] The horizontal flue of a boiler is the pipe through which the flue gas generated during the boiler heating process passes. The boiler flame deflector is a triangular protrusion on the upper part of the rear wall of the boiler combustion chamber that extends into the furnace. The function of the flame deflector is to increase the length of the horizontal flue. Since the flame deflector extends into the furnace, it is equivalent to increasing the length of the horizontal flue by one flame deflector. In this way, more superheater heating surfaces can be arranged without increasing the depth of the boiler. Therefore, the horizontal flue and the flame deflector of the boiler are connected structures and are used together to discharge the flue gas generated by boiler combustion.

[0003] During boiler operation, a large amount of fly ash accumulates on the flame deflector and horizontal flue heating surfaces, which is a long-standing and difficult problem to solve. It not only weakens the heat transfer of the boiler heating surfaces, resulting in reduced boiler thermal efficiency and reduced production load, but also may lead to unexpected shutdowns and significant economic losses when the ash and slag on the heating surfaces are severe. Currently, most boilers are equipped with traditional mechanical soot blowers, sonic soot blowers, gas shock wave soot blowers, air shock wave soot blowers, compressed air shock wave soot blowers, etc.

[0004] When using existing flame deflector soot blowing devices, the soot blowing nozzles are evenly spaced on the upper side of the flame deflector structure. The steam blown from the circular air holes on the soot blowing nozzles will have dead zones, making it impossible for the blowing nozzles to effectively blow away the dust accumulated on the upper side of the flame deflector structure. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a boiler horizontal flue deflector soot blowing device. Through the arrangement of a first and second vibrating motor, a purging nozzle, a rotating disk, steam oblique spray holes, and inclined flat spray holes, the first and second vibrating motors vibrate the deflector structure during dust blowing, loosening the dust. High-pressure steam is blown out through the inclined flat spray holes on the purging nozzles into a triangular purging range. The staggered purging nozzles cover the purging area of ​​the preceding nozzles, allowing for effective dust blowing. The steam oblique spray holes on the rotating disk rotate under the action of high-pressure steam, creating a turbulence area above the purging nozzles, preventing the blown dust from falling onto the deflector structure and allowing it to be discharged with the boiler exhaust gas, thus ensuring the soot blowing effect and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a boiler horizontal flue flame deflector soot blowing device, comprising a flame deflector structure, a purging nozzle is provided on the upper inclined side of the flame deflector structure, a rotating disk is rotatably connected to the upper end of the purging nozzle, three steam oblique spray holes are circumferentially opened on the rotating disk, an inclined flat spray hole is provided on the side of the purging nozzle, the purging nozzle is staggered on the upper inclined side of the flame deflector structure, a first vibration motor is provided on the upper edge of the lower side of the flame deflector structure, and a second vibration motor is provided on the lower edge of the lower side of the flame deflector structure.

[0007] Furthermore, a steam pipe is connected to the lower side of the purging nozzle, and a valve is installed on the steam pipe.

[0008] Furthermore, a steam box is connected to one end of the steam pipe near the valve, and the steam box is connected to the steam pipe via a flange.

[0009] Furthermore, the steam pipe is connected to the valve via a flange, and the steam pipe is connected to the purge nozzle via a threaded connection.

[0010] Furthermore, the purge nozzle is connected to the flame deflector structure via a threaded connection, and the first vibration motor and the second vibration motor are connected to the flame deflector structure via bolts.

[0011] Furthermore, the rotating disk and the purging nozzle are connected by bearings, and the longitudinal axis of the steam oblique spray hole is tangent to the outer ring side of the rotating disk.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a No. 1 vibration motor, a No. 2 vibration motor, a purging nozzle, a rotating disk, a steam oblique spray hole, and an inclined flat spray hole, enables the No. 1 and No. 2 vibration motors to vibrate the flame deflector structure during dust purging, loosening the soot. High-pressure steam is blown out into a triangular purging range through the inclined flat spray hole on the purging nozzle. The staggered purging nozzle can cover the purging area of ​​the front purging nozzle, thus enabling the purging nozzle to effectively purge the soot. The steam oblique spray hole on the rotating disk can rotate under the action of high-pressure steam, thereby forming a turbulence area on the upper part of the purging nozzle, preventing the blown soot from falling onto the flame deflector structure, allowing the soot to be discharged with the boiler exhaust gas, thus ensuring the soot blowing effect.

[0021] like Figure 1-4 As shown, after the boiler flame and flue gas pass through the flame deflector structure 1, they flip upwards and move. The soot in the flue gas falls onto the upper side of the flame deflector structure 1. When purging is required, the high-pressure steam in the steam box 5 is transported to the purging nozzle 2 through the steam pipe 3. The steam is blown downwards through the inclined flat nozzle 7 into a triangular area, which can cover and purge the front purging nozzle 2, avoiding purging dead corners and ensuring purging effect. During purging, the first vibration motor 6 and the second vibration motor 8 can vibrate, which can shake off the accumulated soot, making it easier to purge. The rotating disk 9 rotates under the reaction force of the high-pressure steam blown out by the steam inclined nozzle 10, which can form a turbulence area on the upper side of the flame deflector structure 1, preventing the blown soot from falling back onto the flame deflector structure 1, and allowing some of the blown soot to be discharged with the boiler exhaust gas.

[0022] A steam pipe 3 is connected to the lower side of the purging nozzle 2, and a valve 4 is installed on the steam pipe 3.

[0023] Steam pipe 3 is connected to steam box 5 at one end near valve 4, and steam box 5 is connected to steam pipe 3 via a flange.

[0024] Steam pipe 3 is connected to valve 4 via a flange, and steam pipe 3 is connected to purge nozzle 2 via a thread.

[0025] The purge nozzle 2 is connected to the flame deflector structure 1 by a thread, and the first vibration motor 6 and the second vibration motor 8 are connected to the flame deflector structure 1 by bolts.

[0026] The rotating disk 9 and the purging nozzle 2 are connected by bearings, and the longitudinal axis of the steam oblique spray hole 10 is tangent to the outer ring side of the rotating disk 9.

[0027] The working principle of the boiler horizontal flue flame deflector soot blowing device provided by this utility model is as follows: Figures 1-4 As shown, after the boiler flame and flue gas pass through the flame deflector structure 1, they flip upwards and move. The soot in the flue gas falls onto the upper side of the flame deflector structure 1. When purging is required, the high-pressure steam in the steam box 5 is transported to the purging nozzle 2 through the steam pipe 3. The steam is blown downwards through the inclined flat nozzle 7 into a triangular area, which can cover and purge the front purging nozzle 2, avoiding purging dead corners and ensuring purging effect. During purging, the first vibration motor 6 and the second vibration motor 8 can vibrate, which can shake off the accumulated soot, making it easier to purge. The rotating disk 9 rotates under the reaction force of the high-pressure steam blown out by the steam inclined nozzle 10, which can form a turbulence area on the upper side of the flame deflector structure 1, preventing the blown soot from falling back onto the flame deflector structure 1, and allowing some of the blown soot to be discharged with the boiler exhaust gas.
