Embodiment

[0043] Such as Figure 4 As shown, it is a schematic structural diagram of a large-diameter rotary heat exchanger rotor. The large-diameter rotary heat exchanger rotor includes a central cylinder, and the central cylinder is composed of a guide end shaft 1, an upper end cover 2, The central cylinder 3, the lower end cover 4 and the supporting end shaft 5 are composed. The periphery of the rotor is divided into a heat transfer element compartment grid 14 by a radial partition 6, a rotor arc shell plate 7, and a transverse partition 8. The connection between the radial partition 6 The connecting plate 10, the connecting pin hole 11 and the connecting ear plate 9 of the central cylinder are connected to form a cantilever beam structure, and the outer peripheral part is provided with a middle radial partition (24).

[0044] The inner radial compartments A1, B1, C1, and D1 of the heat transfer element compartment grid 14 are one compartment, and the outer radial compartments E, F, ...

Abstract

The invention relates to the rotor of a rotary heat exchanger with large diameter, which comprises a central drum consisting of a guide end axle, an upper end cap, the central drum, a lower end cap and a bearing end axle. The rotor is characterized in that the periphery of the rotor is divided into heat transmission element hoppers by a radial clapboard, a rotor arc shell plate and a transverse clapboard; the connecting approach slab and the connecting pin hole of the radial clapboard and the connecting ear plate of the central drum are connected into a cantilever beam structure; in the heat transmission element hoppers, A1, B1, C1 and D1 are a hopper, while E, F, G and H are two hoppers; the radial clapboard is a structure with a thicker inner segment and a thinner outer segment. The rotor has the advantages of solving the purchasing difficulty of too thick armor plates adopted of central drums with large-sized rotors, reducing material by not lower than 20 percent, being able to obviously reduce the size of useless working area of the rotor, improving material utilization efficiency and effectively reducing the flowing resistance of smoke-laden air when equipment is operated.

Description

technical field [0001] The invention relates to a large-diameter rotary heat exchanger rotor structure, which is used for the rotary air preheater and the rotary flue gas heater of the desulfurization system of a large-scale thermal power generating set over 12 meters, and belongs to the rotary heat exchanger technology field. Background technique [0002] The rotor of the rotary heat exchanger is the core part of the equipment. The purpose is to accommodate heat transfer elements, and use radial partitions to divide them into multiple independent radial compartments, so as to cooperate with upper and lower radial sealing plates to form a complete sealing area to isolate two kinds of circulating heat exchange media with different pressures or components. The weight of the rotor and its contents accounts for more than 60% of the total weight of the preheater, the maximum diameter can reach more than 20 meters, and the maximum weight can reach nearly 1,000 tons. [0003] The...
