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 regenerative heat exchanger (1) has a heat accumulator designed as rotor, where the accumulator is pivoted around a central rotary axis (A). The heat from a gas volume flow (V) arising by the rotor (2) is transferred to another gas volume flow arising by the rotor, where a sealing system is provided for the rotor. The sealing system has seals (4,5) fixed against the rotor. The seal on one hand is pressed on the rotor and on the other hand is held at the rotor.

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 consists of two face sides, an outer shroud and a partition that typically accommodates 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...
