Arrangement for flow guidance in tube bundle heat exchangers for the thermal treatment of suspensions

摘要

The invention relates to an arrangement for the flow guidance in tube bundle heat exchangers for the thermal treatment of suspensions which contain lumpy and / or long-fiber constituents. With the invention, the clogging susceptibility given in tube bundle heat exchangers according to the prior art is largely eliminated. This is achieved in that, viewed in the flow direction, the first tube bundle (100.1, 101.1, 102.1) is preceded by an inlet and distributor device (10) with a distributor body (10.3), which forms a distributor space (V) on the inside, that the distributor space (V) with each inner tube (300; 300 *) of the first tube bundle (100.1; 101.1, 102.1) via a respective distributor tube (10.1.i; 10.1.i, 10.2.i) from a group of distributor tubes (10.1; 10.1, 10.2) is separately connected, wherein the distance of adjacent distribution pipes is at least as large as the length of the fibrous components, and that each inner tube (300, 300 *) of a tube bundle (100.i; 101.i, 102.i) with an associated inner tube (300; 300 *) of the subsequent tube bundle (100.i + 1; 101.i + 1, 102.i + 1) are connected separately via a connecting bend (20.1.i) from a group of connecting sheets (20.1) of the connecting fitting (20) is (Figure 2).
