Example Embodiment
[0045] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] Such as image 3 , Figure 4 Shown is a specific embodiment of the present invention.
[0047] The radial superimposed flexible sealing device applied to the rotary air preheater mainly includes a flexible contact sealing device 6 and a brush sealing device 7 arranged between the sector plate 1 and the rotor radial partition 5. The contact type sealing device 6 and the brush type sealing device 7 are fixedly connected to the radial partition 5 of the rotor by bolts 8. Of course, the contact type sealing device 6 can be separately provided for sealing.
[0048] Since in the rotary air preheater, the rotor and the housing are in a rotary motion relationship, there is a dynamic gap 3 between the working end of the original sealing sheet 4 and...
