Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a vertical chamber containing an artificial joint for a pressurized heating medium in an upper region and an outlet joint for a nuclear heating medium in a lower region. are arranged coaxially with each other in the chambers, their lower ends being connected to an inlet joint and their upper ends communicating with an outlet joint for the medium to be heated. % boiling matshu or wort heat exchanger.

A heat exchanger of the above type is the subject of German utility model No. G 8031264.7 by the applicant. It is distinguished by good high temperature efficiency and particularly simple maintenance.

The object of the present invention is to further improve the efficiency of the heat exchanger and at the same time simplify its structure.

This object is achieved according to the invention by arranging a cylindrical displacement body in a space surrounded by the innermost helical pipe +=X, and by communicating the inside of said displacement body with the room containing the helical pipe. Ru.

The flow chamber for the heating medium (preferably steam) is reduced in size by this displacement body, so that the heating medium flows with a greater velocity into the helical pipe containing the medium to be heated. This heat exchanger is thus further improved.

In the structure according to the present invention, the cylindrical displacement body is communicated with the chamber through the helical pipe through which the heating medium flows, so that the opening pressures of these two chambers can be balanced. This has a particularly pronounced loading effect when the heating medium is delivered at increased pressure. In this case, the cylindrical displacement body should experience no resistance to compression due to pressure equilibrium, which makes its construction lighter and more economical.

The present invention will now be described in more detail by way of example and with reference to the drawings.

The heat exchanger (1) according to the present invention is shown as a vertical sectional view in the somewhat structured drawing. This heat exchanger...
A vertical housing (2) containing a cylindrical peripheral wall (31) and an upwardly curved cover (4).
and a downwardly curved substrate +51, a pressurized heating medium inlet joint (6) in the upper region, and this heating medium outlet joint (71) in the upper region.In the illustrated embodiment, the above-mentioned inlet joint (6) is the upper end of the housing, its cover (4
) and said outlet fitting (7
) is arranged centrally on the substrate (5) at the lower end of the housing. This housing (2) is constructed to withstand compression and also has a pressure-resistant closable access opening (8) in the region of the upper end of the wall (3).

In order to heat the medium to be heated, in this case matshu or wort, in said housing (2) by indirect heat exchange to boiling, a small number of (two helical pipes) are installed inside said housing (2). The number of helical pipes is generally the same as the heat exchanger (
Determined by the size and weight of 1). In the illustrated embodiment, four helical pipes f91, Q(1, Qυ, and u) are sequentially aligned coaxially with respect to 5(28)K of the inner 1IiIK container. That is, these helical pipes (9) to
02J constitutes a cylindrical structure.

The lower end of each of these helical pipes (91-oz. Since these inlet and outlet fittings of eve (9) to 03 are preferably combined into a well-known manifold, a common inlet romaehold uJ is provided at the lower end of the helical vibe (9) to α2 and a common outlet romaehold 04 is provided. is provided at the upper end for all No(9) to Q7J.

The cylindrical displacement body 051 is the innermost helical pipe a' inside the housing (2). It is located in the S-ya surrounded by JVc. This displacement body has a substantially dome structure and its lower end is open, so that its inner chamber (1
61 is connected to a helical pipe (external force container chamber Q7 containing 91 to α2) K. This displacement body is arranged at the same pressure inside the innermost helical pipe a2J, and is also coaxial with the container (2).
5+ is constructed in the shape of a tube over its entire height and has an upwardly curved cover portion Q81 at its upper end, whereas its lower end (151) is completely open. Due to this arrangement inside the container (2), the displacement body a
The lower open end of 9 is located directly above the heating medium outlet fitting (9) provided in the center of the housing base plate (5).

At the lower end (15a) of the displacement body Q9, there is an open communication between the outer container chamber (17) on the one hand and the inner chamber (161) of the displacement body (161) and the heating medium outlet row arm (7) on the other hand. For this purpose, the open lower end (15g) of the displacement body a9 is provided with a plurality of notches in the area of its lower edge (151), and these are arranged around the periphery of the displacement body. The remaining part of this lower rim (15a) is supported directly on the base of the downwardly curved housing (2). From the chamber a1 (which contains the helical pipes (9) to α2) it is possible to take in to the outlet A-tsute (7), and on the other hand between this outer container chamber 0 and the inner chamber 0610 of the displacement body. While allowing pressure equilibrium, the °C displacement body can be made of a relatively light structure.

The fixing of the helical pipes (9) to a3 inside the outer annular container chamber 0η is as follows.

A number of vertical carriers are distributed along the periphery of the container and supported on the container substrate (5), and a plurality of substantially horizontally extending brackets are provided at specified spacings over the entire height of these vertical carriers. The stacked bundles of these pipes are rigidly attached (supported) to the outer circumferential wall (3) K of the container on the one hand and to the cylindrical displacement body (15) on the other hand, so that no apparent movement of these parts due to expansion occurs. maintained between.

The cleaning fluid supply device is connected to the upper part of the outer container chamber (1
7a) is provided above the helical pipes (91 to α2). In this embodiment, the annular spray pipe for anti-fouling fluid (201 is provided and the outer pipe cultivator t21f is If necessary, the cleaning fluid can be introduced into the container (21) through this spray pipe R2 (J) and sprayed onto the helical pipe +91~02J. (not shown) or the outlet fitting (7) can be extracted with any diameter.

To mount the heat exchanger (11), a plurality of mounting supports (only one of which is shown in detail) is attached to the container substrate (5).
) These supports can be provided at their lower ends with feet adjustable in height.
