Embodiment Construction

[0018] figure 1 A regenerative heat exchanger designated with reference number 1 is shown, of which only one half of the symmetrical structure is shown. The regenerative heat exchanger 1 comprises a rotor 2 which is held rotatably about a vertical axis of rotation A and is arranged in a rotor housing 3 . A plurality of gas volume flows V flow through the rotor 2 so that heat is transferred from at least one gas volume flow to at least another gas volume flow. A sealing system with a radial seal 4 and a circumferential seal 5 is provided for sealing the gas volume flow V guided through the regenerative heat exchanger 1 . The radial seal 4 is arranged on the front side of the rotor 2 and is provided for preventing a short-circuit volume flow between the gas volume flows V. FIG. The circumferential seal 5 is arranged on the face edge of the rotor 2 and is provided to prevent a leakage volume flow from entering the rotor housing 3 . The radial seal 4 and the circumferential sea...

Abstract

The invention discloses a regenerative heat exchanger (1) comprising a regenerator arranged as a rotor (2) and rotatably held about a central axis of rotation (A) and will flow through the rotor (2) The heat of at least one gas volume flow (V) is transferred to another gas volume flow flowing through the rotor (2), and the regenerative heat exchanger (1) includes a sealing system for the rotor (2). It is provided that the sealing system includes at least one seal (4, 5) which is fixed relative to the rotor (2) and which presses the rotor (2) on the one hand and the rotor (2) on the other hand. The rotating rotor (2) is supported by a plurality of rollers (12, 18). In particular, the invention relates to a regenerative heat exchanger with a positively guided rotor seal.

Description

technical field [0001] The invention relates to a regenerative heat exchanger of the type according to the preamble of claim 1 . Background technique [0002] Various types of regenerative heat exchangers are used for heat transfer from at least one gas volume flow to at least another gas volume flow. The rotating heat accumulator, the so-called rotor, is heated by at least one gas volume flow and cooled again by at least another gas volume flow in an alternating manner, so that thermal energy is transferred from one gas volume flow to the other. As a result, one gas volume flow can be heated and the other gas volume flow can be cooled. The rotor comprises two facesides, an outer shroud and usually a partition for accommodating multiple heat accumulators. The rotor is held rotatably about a central rotational axis, which is preferably vertically aligned. [0003] In order to seal off the gas volume flow guided through the regenerative heat exchanger, a sealing system with...
