Thus, paper pads are arranged between the guide column 6 and the upper wear-resistant lining ring 4 and between the guide column 6 and the lower wear-resistant lining ring 5, so that rigid contact between the guide column 6 and the upper wear-resistant lining ring 4 and between the guide column 6 and the lower wear-resistant lining ring 5 is avoided, and the buffer protection effect is achieved.
Referring to fig. 2, the bottom end of the shaft sleeve 3 is symmetrically provided with screw holes 8 for adjusting dynamic balance. Like this, through adjusting the screw of installing on screw 8, can adjust atomizing disk balance performance when rotating for atomizing disk has fabulous balanced precision when high-speed rotatory.
Referring to fig. 1-3, the upper plate 1 and the lower plate 2 are made of titanium alloy. The titanium alloy has high specific strength and lighter weight under the same volume compared with the traditional steel material; on the other hand, the titanium alloy has good corrosion resistance, and is not easy to corrode in the acidic environment of flue gas desulfurization, so that the atomizing disc has longer service life.
The working principle of the reinforced wear-resistant atomizing disk is as follows:
lime slurry enters from a feed inlet in the middle of the atomizing disc, and the atomizing disc rotates at a high speed; the lime slurry entering the atomizing disc is diffused to the upper surface of the lower disc 2, and the centrifugal force generated by the atomizing disc rotating at high speed acts on the lime slurry, so that the lime slurry is discharged from an atomizing opening formed by two adjacent guide columns 6, the upper wear-resistant lining ring 4 and the lower wear-resistant lining ring 5, and a layer of uniform mist is formed around the atomizing disc. Because the upper wear-resistant lining ring 4 is arranged between the bottom of the upper disc 1 and the tops of the guide columns 6, and the lower wear-resistant lining ring 5 is arranged between the top of the lower disc 2 and the bottoms of the guide columns 6, the atomizing ports formed by the two adjacent guide columns 6, the upper wear-resistant lining ring 4 and the lower wear-resistant lining ring 5 do not form splicing seams extending along the radial direction, and the lime slurry is separated from the upper disc 1 and the lower disc 2 by the closed atomizing ports in the high-speed discharge process of the lime slurry from the atomizing ports, so that the upper disc 1 and the lower disc 2 are prevented from being abraded at the positions of the atomizing ports by the lime slurry, and the service life of the atomizing discs is prolonged; meanwhile, when the lime slurry moving at a high speed impacts the inner end face of the guide column 6 to back flush, the lime slurry impacts the upper wear-resistant lining ring 4 and the lower wear-resistant lining ring 5, namely the upper wear-resistant lining ring 4 and the lower wear-resistant lining ring 5 avoid the abrasion of the upper disc 1 and the lower disc 2 caused by the reverse movement when the lime slurry impacts the end face of the guide block, and the service life of the atomizing disc is prolonged; on the other hand, the atomizing port is composed of a split flow guide column 6, an upper wear-resistant lining ring 4 and a lower wear-resistant lining ring 5, the structure of each part is simpler, the processing difficulty is effectively reduced, and the follow-up maintenance is convenient.
Example 2
Referring to fig. 4, the difference between this embodiment and embodiment 1 is that in this embodiment, the outer circumferential side surfaces of the lower wear-resistant bushing ring 5 and the upper wear-resistant bushing ring 4 exceed the outer end surface of the diversion column 6, and the top of the lower wear-resistant bushing ring 5 is provided with a first closed groove for accommodating the bottom of the diversion column 6; and a second closed groove for accommodating the top of the guide column 6 is formed at the bottom of the upper wear-resistant lining ring 4. The upper wear-resistant bushing ring 4 and the lower wear-resistant bushing ring 5 are arranged in the structure, the guide column 6 is completely installed between the first closed groove and the second closed groove, the upper wear-resistant bushing ring 4 and the guide column 6 and the lower wear-resistant bushing ring 5 and the guide column 6 are completely separated, thus an atomizing opening formed by the guide column 6, the upper wear-resistant bushing ring 4 and the lower wear-resistant bushing ring 5 is completely separated from the atomizing disk, no radial splicing seam is formed between the atomizing openings, and the upper disk 1 and the lower disk 2 can be better prevented from being abraded at the position of the atomizing opening by lime slurry.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
