DE10000018A1 - Reactor vessel has inner lining made of small strips or tiles of material resisting high temperatures and poor thermal conductivity - Google Patents

Abstract

A reactor vessel (1) has interior insulation comprising insulation elements or strips (6) each separated from the adjacent element or strip by a gap (8) and made of materials capable of resisting high-temperatures and having low heat conductivity. Preferred Features: The insulation material is bonded to the reactor vessel inner wall. The insulating material elements are 250-350 mm in length, 30-70 mm wide, and 1-5 mm thick. Insulating strips are 30-70 mm wide and 1-5 mm thick. The gap between adjacent elements and strips (6) is 0.2-5 mm wide.

Description

The invention relates to a container for carrying out reactions of any kind, the has internal insulation at least in partial areas.

In the following, the term “container” refers to adsorbers or adsorption containers, Understand reactors, columns, separators, etc.

When developing adsorbers in the sixties it was reducing a loss of heat loss in the edge area of the thick-walled pressure vessel Containers made of thin-walled chrome-nickel steel installed. This construction was although it was very expensive and in the event of a leak in the inner container the function of the adsorber significantly disturbed, used for many years. The Further development towards a more cost-effective construction finally led to the so-called bulkhead walls with annulus flushing.

Adsorbers, especially molecular sieve adsorbers, such as those used for (Pre) purification of air at air separation plants are provided in the Usually regenerated with a hot gas after the end of the adsorption phase. To ensure that at the edge zones in the area of the comparatively thick Container wall as little heat as possible is lost in such Adsorber constructions are expediently provided with internal insulation.

The above constructions - additional container or bulkhead - have however, the disadvantage that a slight leak at connection points Bypass occurs over part of the bed or even the entire bed. This severely limits the function of the adsorber, if not even that becomes completely inoperable.

The object of the present invention is to provide a container for carrying out Specify reactions of any kind that avoid the disadvantages mentioned.  

This is achieved according to the invention in that the inner insulation in the form of insulating elements and / or insulating strips arranged on the inner wall of the container is trained.

In the case of the container according to the invention, a second container or a bulkhead can be dispensed with. Rather, a variety of Insulating elements and / or strips arranged on the inner wall of the container.

Advantageously, at least in the direction of flow of the or remains media flowing between the individual insulating elements and / or -strip a fugue.

The result of this configuration is that even when individuals are replaced Insulating elements and / or strips do not create a bypass over the (whole) fill can. Thus, even in these cases, it can still be economical and reliable Function of the container can be guaranteed. This form of interior insulation is moreover, comparatively inexpensive, since the insulating elements and -strips can be produced in large numbers.

According to a further advantageous embodiment of the container according to the invention the insulating elements and / or strips consist of a temperature-resistant Material, the choice of material depending on the later use of the container depends.

Furthermore, it is expedient if the insulating elements and / or strips have a low Have thermal conductivity, since the heat losses are further reduced can.

In principle, there are a variety of fastening options for the insulating elements and / or strips on the inner wall of the container conceivable; expediently however, they are glued to the inside wall of the container, choosing the adhesive used for this also increases its temperature resistance is taken into account.  

The container according to the invention and further refinements of the same are explained in more detail below with reference to FIGS. 1 to 3.

Here, the Figure 1 demonstrated. A side sectional view through an adsorber or adsorbent tank, while Figs. 2 and 3 possible shapes of the insulating elements or strips show.

Two of the adsorber or adsorption vessel 1 shown in Fig. 1 has oppositely disposed inlet and outlet openings 2 and 3. In the area of the adsorbent fill, the adsorber 1 has an internal insulation - referred to as insulation area 4 in FIG. 1.

This insulation area 4 can now - as shown in FIGS. 2 and 3 - be provided with insulating strips 6 ( FIG. 2) or insulating elements 7 ( FIG. 3). Of course, combinations of insulating elements 7 and strips 6 can also be realized.

In the section 5 of the insulation region 4 shown in FIG. 2, the inner insulation is in the form of insulating strips 6 . These insulating strips 6 are preferably glued all around in one piece on the inner wall of the container 1 . These insulating strips 6 preferably have a width between 30 and 70 mm and a thickness between 1 and 5 mm. Their length is determined by the container dimensions.

The section 5 shown in FIG. 3 from the insulation area 4 of the container 1 shows a possible arrangement of insulating elements 7 , which should preferably be arranged offset to one another. According to an advantageous embodiment, these insulating elements 7 have a length between 250 and 350 mm, a width between 30 and 70 mm and a thickness between 1 and 5 mm.

The joints 8 between the individual insulating elements 7 or insulating strips 6 preferably have a width between 0.2 and 5 mm.

The insulating elements and strips described have the due to their size Advantage that they are exposed both to the thermal stresses can easily withstand mechanical loads. Furthermore, too in the event of damage or chipping or falling off of individual insulation elements no disruptive bypass created.

These insulating elements or strips are also inexpensive and comparative easy to attach to the inside wall of the container.

Containers already in operation can also be used with the aforementioned Insulating elements and / or strips are retrofitted.
