本专利系回转式空气预热器或类似设备的转子与罩壳端板间的径向密封的改进结构。容克式回转式预热器其圆筒状转子具有许多装载传热元件用的舱格,当转子转动时这些元件首先置于烟气下受热,然后再置于空气下将吸收的热量放给空气。转子由一罩壳包住,此罩壳由端板或扇形板组成一些开口使烟、空气通过。为了防止两种流体的混合,转子舱格的隔板都装有径向密封,此密封再与扇形板的无孔部分连在一起,或者将此密封设在扇形板上,再与径向隔板连在一起。
The patent is a rotary air preheater or similar device rotor and shroud radial seal between the improved structure. The Junker rotary preheater has a cylindrical rotor with a number of compartments for carrying the heat transfer elements which, when the rotor is rotating, are first placed under a flue gas and then exposed to air to release the absorbed heat air. The rotor is surrounded by a casing which is made up of an end plate or sector plate with openings through which smoke and air can pass. In order to prevent mixing of the two fluids, the rotor compartment partitions are fitted with radial seals, which in turn are connected to the non-perforated sections of the sector plates or the seal is placed on the sector plates, Board together.
