[0001] The present application relates to the technical field of flue cleaning, and in particular to a flue cleaning device for a desulfurization tower. Background Art

[0002] In the prior art, the cleaning of the flue of the desulfurization tower is usually carried out by physical water pressure cleaning and chemical cleaning methods; although these methods can remove the dust and dirt in the flue to a certain extent, hydraulic cleaning will produce a large amount of waste liquid containing impurities, and chemical agents are easy to pollute the environment, and the harmless treatment of these waste liquids requires complicated and costly processing procedures. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0017] The present application relates to a flue 3 cleaning device for a desulfurization tower, such as Figure 1-9 As shown, the cleaning device includes a body 1 for basic support and accommodation, and a plurality of groups of walking components 2 capable of walking along the inner wall of the flue 3 are evenly arranged in the circumferential direction of the outer side of the body 1. Since the diameters of different flues 3 vary, in order to be able to adapt to flues 3 of various diameters, the walking components 2 have the function of elastic and adaptive adjustment to automatically adapt to flues 3 of different diameters. Since a large number of solid impurities are attached to the upper part of the inner wall of the flue 3, in order to achieve effective cleaning of the flue 3, a cleaning component 4 that uses a rotating method to perform crushing and cleaning operations is arranged at the front end of the body 1.

[0018] The cleaning component 4 includes a crushing member 7, a cleaning member 6 and a motor 5. The crushing member 7 is arranged at the front end and uses a rotating manner to perform a rigid cutting and crushing operation on the impurities on the upper part of the inner wall of the flue 3. The cleaning member 6 is arranged directly behind the crushing member 7 and is used to perform a flexible cleaning and impurity removal operation on the crushed impurities on the upper part of the inner wall of the flue 3. The motor 5 is arranged directly behind the cleaning member 6 and is connected to the crushing member 7 and the cleaning member 6 in sequence through a shaft rod, so that the motor 5 drives the crushing member 7 and the cleaning member 6 to operate at the same time through the shaft rod, and performs a rigid and flexible composite cleaning operation on the impurities on the upper part of the inner wall of the flue 3.

[0019] The crushing member 7 includes three cutting discs 8, which are evenly and spaced apart on the upper part of the shaft, and the diameter increases from front to back. In order to achieve progressive crushing of impurities and avoid breaking of the cutting discs 8 due to greater impact in places where the flue 3 is severely blocked, the diameter ratio between the cutting discs 8 is 1:1.77:2.54. In order to improve the crushing effect of the cutting discs 8 on impurities, tooth blades 9 folded to both sides are evenly and staggeredly arranged at the edges of the cutting discs 8, thereby improving the crushing effect with the help of the staggered tooth blades 9.

[0020] The cleaning member 6 includes a disc frame 10 and edge pieces 11. The disc frame 10 is arranged in a circular ring shape on the upper part of the shaft and is driven to rotate thereby. The edge pieces 11 for striking the inner wall of the flue 3 to achieve cleaning are evenly arranged in the circumferential direction of the disc frame 10. The edge pieces 11 are made of a wear-resistant and soft rubber material.

[0021] The walking assembly 2 includes a frame plate 18, a track wheel 14, a shock absorber 16, a pull rod 17, and a connecting piece 15. The frame plate 18 is fixedly arranged in the length direction of one side of the body 1. A track wheel 14 for walking is arranged on one side of the upper part of the frame plate 18, and a plurality of pull rods 17 hinged to the frame plate 18 are symmetrically arranged on both sides of the track wheel 14. In order to enable the track wheel 14 to adapt to flues 3 of different diameters, a shock absorber 16 with an elastic load-bearing function is arranged on the upper part of the frame plate 18, and a connecting piece 15 for elastically stretching the track wheel 14 is arranged at one end of the shock absorber 16.

[0022] The connecting member 15 includes a slide bar 19, a spring 20, and a slide seat 21. The slide seat 21 is arranged at one end of the shock absorber 16 and can slide back and forth along the length direction of the frame plate 18. There are two slide bars 19, which are arranged on the sides of the track wheel 14 and the slide seat 21 respectively. The slide bars 19 can be slidably connected to each other, and a spring 20 for elastic pre-tightening is sleeved between the two. When the track wheel 14 abuts against the inner diameter of the flue 3, when the deformation of the track wheel 14 is small, the compensation and adaptation operation can be performed only by relying on the deformation change of the slide bar 19 and the spring 20. When the deformation is large, the shock absorber 16 is driven by the connecting rod to perform telescopic energy absorption operation, so that the track wheel 14 can abut against the upper part of the inner wall of the flue 3.

[0023] In order to facilitate the operation of the cleaning device, a wiring harness interface 12 and a safety rope hanging ring 13 are provided at the rear of the body 1 to prevent the signal inside the flue 3 from being poor and to adopt a wiring harness for control to improve the stability of operation. The safety rope can be manually pulled back when a fault occurs in the cleaning device. Since the cleaning device is a rigid connection structure in the axial direction, it is mainly suitable for straight-cylinder flues 3 to prevent the cleaning device from getting stuck.
