Embodiment 1
[0037] combine Figure 1-Figure 3 , a radial sealing system of a fitted contact type air preheater in this embodiment includes a radial sealing device 200 arranged between the hot end sector sealing plate 110 and the hot end radial partition plate 130 of the rotor 100. The radial sealing device 200 includes an upper sealing unit 201 arranged at the lower part of the hot end fan-shaped sealing plate 110 and a lower sealing unit 202 arranged at the lower part of the hot end radial partition plate 130. The upper sealing unit 201 and the lower sealing unit 202 have the same structure and are symmetrically distributed , the bottom of the upper sealing unit 201 and the top of the lower sealing unit 202 form a mutual fit, and are sealed in pairs, so that the sealing gap of the air preheater can be effectively compensated under the mushroom-shaped deformation state, so as to ensure that the air preheater is still under full load operation. It can ensure a good sealing effect, effectiv...
Embodiment 2
[0043] The radial sealing system of a contact-type air preheater in this embodiment is basically the same in structure as in Embodiment 1. Further, this embodiment also includes a fan-shaped sealing plate 120 disposed on the cold end of the rotor 100 and a diameter of the cold end. The radial sealing device 200 between the partition plates 140 is the same in structure as the radial sealing device 200 disposed between the hot end sector sealing plate 110 and the hot end radial partition plate 130 of the rotor 100, which not only ensures the hot end sector The sealing effect of the sealing plate 110 can also improve the sealing effect of the fan-shaped sealing plate 120 at the cold end of the air preheater, further reducing the air leakage rate of the air preheater, improving the efficiency of the boiler, and reducing the production cost.
[0044] In this embodiment, the hot-end fan-shaped sealing plate 110 and the fixing plate 210 are provided with connecting holes at the corres...
