Description

Technical Field

[0001] This utility model relates to the field of soot blowers, and in particular to a soot blower for the tail flue of a boiler. Background Technology

[0002] A soot blower is a device used to remove ash accumulation on the heating surfaces of a boiler. It typically consists of a soot blowing pipe and operating valves, and is generally installed on the furnace walls in the boiler furnace, horizontal flue, and tail flue. For coal-fired boilers, coking on the water-cooled walls of the furnace, coking on the high-temperature superheater and reheater, and ash accumulation on the tail heating surfaces are common and unavoidable phenomena. Severe ash accumulation on the tail heating surfaces can reduce the heat transfer efficiency of the superheater, reheater, economizer, and air preheater, increase the boiler exhaust temperature, and reduce boiler efficiency. Coking and ash accumulation on the heating surfaces can also cause overheating, exacerbate corrosion, shorten the service life of the heating surfaces, and in severe cases, affect the normal operation of the boiler and even endanger the personal safety of inspection personnel. Therefore, a soot blower is essential. Existing devices can generate shock waves through compression control to blow away ash, but the coke shells on the inner side of the flue are connected and difficult to be broken up by the shock waves in a short time, resulting in a significant reduction in cleaning efficiency. Therefore, this utility model aims to improve the existing equipment to address the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses a boiler tail flue soot blower, including an air inlet pipe 1, which is a rubber hose and connected to a compressor air supply device. The other end of the air inlet pipe 1 is connected to a shock tank 7, which is equipped with a shock wave assembly. The other side of the shock tank 7 is connected to a waveguide cylinder 10, which is equipped with a conveying assembly. The front end of the waveguide cylinder 10 is equipped with a turning nozzle 14, which is equipped with an adjustment assembly and is connected to the boiler tail flue. The upper end of the outer side of the waveguide cylinder 10 is connected to a chiller 16, which is equipped with a cooling assembly. The modular design facilitates device maintenance and upgrades, improving practicality. The shock wave assembly includes a multi-way connecting pipe 2, and a pressure gauge 3 is connected to the interface on the lower outer side of the multi-way connecting pipe 2. The pressure gauges 3 are symmetrically positioned vertically. The interface is connected to a compensating air pipe 4, the other end of which is connected to a shock tank 7. The last end of the multi-connector pipe 2 is connected to the shock tank 7 via a vent pipe 6. The other end of the outer side of the shock tank 7 is connected to a wave outlet pipe 8. A conveying assembly is connected to the wave outlet pipe 8. The conveying assembly includes an air inlet pipe 9, which is connected to the rear side of the outer side of the waveguide tube 10. A cold air inlet 11 is connected to the upper middle part of the outer side of the waveguide tube 10. A cooling assembly is connected to the cold air inlet 11. An adjustment assembly is provided on the front and rear end faces of the waveguide tube 10. The adjustment assembly includes a chassis 12, which is rotatably connected to the rear end face of the waveguide tube 10. A connecting column 13 is horizontally fixed to one side of the front end face of the chassis 12. A steering nozzle 14 is fixed to the other end of the connecting column 13. The steering nozzle 14 is rotatably connected to the front end face of the waveguide tube 10. The fixed end of the cylinder 15 is hinged to the rear end of the outer side of the waveguide 10. The telescopic end of the cylinder 15 is rotatably connected to the outer periphery of the rear end face of the chassis 12. The cylinder 15 is connected to the compensation air pipe 4 through the control air pipe 5. With the cooperation of the shock wave assembly and the conveying assembly, it is easy to generate shock waves by oscillating the compressed gas in the device, thereby bombarding the flue and blowing away the dust, which improves the practicality.

[0020] In this invention, to solve the problem that existing equipment's shockwaves are difficult to clean large, tightly adhered dry shells, the following technical solution is adopted: The cooling component includes a chiller 16, which is installed and fixed on one side of the shockwave tank 7. The side of the chiller 16 is connected to the cold air port 11 on the waveguide cylinder 10 through a cold air pipe 17. Through the cooperation of the cooling component and the conveying component, it is convenient to pre-blow away the relatively loose surface dust while cooling the deep dry shells, causing them to cool and shrink, thus cracking into small pieces that are easier to detach, thereby improving the cleaning quality.

[0021] Working principle: When using this utility model, firstly, power is supplied to all electrical equipment, then the gas inlet pipe 1 and the gas supply equipment are connected, and then the diverting nozzle 14 and the boiler are connected. When flue cleaning is required, a short burst of high-pressure air is introduced through the gas inlet pipe 1. The air will enter the shock tank 7 through the multi-port connecting pipe 2, and the kinetic energy will be transferred to the air in the shock tank 7, causing the air to vibrate and heat up. It will then enter the wave guide tube 10 through the wave outlet pipe 8, and finally be sprayed out from the diverting nozzle 14 to clean the dust on the inner wall of the flue. Before or during cleaning, the chassis 12 can be rotated by controlling the gas pipe 5 and the cylinder 15, thereby rotating the diverting nozzle 14 and changing the direction of the shock wave. Alternatively, the cooling air can be injected into the flue by cooperating with the refrigeration unit 16 and the cold air pipe 17, causing the coke shell to shrink and crack due to the cold, so that the shock wave can better impact and remove the dirt.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
