I. Completion of the emptying side of
Degassing rooms.

The doors to the closure and to pull out the degassed materials are on the Previous degassing rooms (e.g. coke ovens) with intermittent operations set up in such a way that that the same, to prevent the entry of air into the degassing rooms, with clay or Thon to be spread well.

The doors are set up either to open or to turn.

The latter device is shown in an example in FIGS.

The dividing lines 1-2 and 3-4 are drawn here as in the following figures because the heights of the doors as well as the heights of the degassing rooms can be different.

At Lürmann's degassing rooms with continuous operation, without a larger anteroom to collect the degassed products, in which the degassed materials (e.g. coke) moved out in shorter periods of time than in the degassing rooms with intermittent operations would have to be, if one does not want to attach the closures of the gas retorts, that Covering the doors with clay or clay causes too much work and a considerable amount of work Require amount of an expense related material. As in previous descriptions highlighted to Lürmann's degassing rooms with continuous operations, it comes with the degassing of certain materials Very careful to avoid any cooling, and it is very important to keep cold air from entering to make any emptying of the degassed materials quickly and completely impossible.

At the same time, a material should be used for sealing, which is always to hand on the emptying side of the degassing chambers and which absorbs the oxygen in the air passing through it, so it does not enters the degassing room and oxidizes degassed materials or gases.

As such a material, the degassed material is used to seal the discharge opening respectively the door attached in front of it was taken, which because of too small size not to that intended use.

So there are z. B. in the degassing of hard coals after the extraction of the good Coke remaining small coke and the so-called ash.

This material, which would otherwise have to be removed, is at hand, seals well, is flammable, is preheated by the heat of the degassing chamber until it ignites, absorbed In this state, the oxygen in the air that is passing through easily and thus heats it End of emptying of the degassing rooms.

This method of closing off the evacuation side with degassed materials is applicable to degassing rooms with continuous Establishments than those with intermittent operations.

In order to be able to use these materials for closure, the closures of the Emptying openings of the degassing rooms with continuous or intermittent operation be specially designed.

Some of these constructions are drawn in FIGS. 3 to 14 and described in the following. If you want the closure of the emptying end of the degassing chambers by a cast iron one To effect the door, the devices shown in FIGS. 3 to 5 and 9 to 11 are selected.

O denotes the emptying opening in all drawn figures, T the door, R the door frame, r the rib on the latter under the door, / the sealing space, which is filled with the sealing, degassed waste material. The sealing space / is, Fig. 3 to S, formed on the sides of the door T by the rotatable flaps K. When these are closed (Fig. 5 left) and attached to the door, the sealing space / "can be filled with the sealing material.

Under the door, the space /, Fig. 4, between the rib r of the frame R and the door is also filled with the sealing material.

These flaps K are necessary when the door T, as shown in Fig. 5, is exposed with refractory bricks.

The flaps K are not absolutely necessary if the door T is not exposed to stones, as shown in Fig. 4; the whole space behind the door T within the opening O is then filled with the sealing material.

In FIGS. 9 to 11 the sealing space f is formed on the sides of T and above in that the masonry of the drainage opening O springs back.

Under the door is / formed by the rib r on the frame R.

If the door is exposed with stones, Fig. 11, two sealing spaces are created on the sides /; If the door T is not exposed with stones, Fig. 10, the whole space behind T, within O, is filled with the material to be sealed.

The method of sealing the emptying opening O by degassed waste material, however, also allows other devices than the cast iron doors described above or those made of wrought iron, which can be exposed with stones. The emptying openings O, as shown in FIGS. 6 to 8 and 12 to 14, can be closed much more easily by means of a light sheet metal funnel and then completely filled with the sealing material described. This funnel T is shown rotatable in Fig. 6 to 8 and shown in Fig. 12 to 14 to be set up.

In the latter case, grasp the funnel T with the aid of the handles h and lift the hooks h ¹ out of the openings on the frame R.

If one removes the funnel T from the opening O in this way or by turning the device in FIGS. 6 to 8, the sealing material falls out and emptying can begin.

If the emptying has taken place, "the funnel is closed or placed in front and..." filled with the sealing material at hand.

These constructions of the closures of the emptying openings are not excluded to seal degassing rooms with materials other than degassed.

II. Gas traps for Lürmann's degassing rooms with continuous operations Extraction of tar, ammonia etc.

i. Gas trap, formed by horizontal, introduced through the piston of the loading device

Tubes.

As in earlier descriptions of Lürmann's degassing rooms with continuous Companies highlighted (Patent No. 16134), For many reasons, these are particularly suitable for the production of oils, tar and ammonia and such _ by-products.

One can for each to be degassed material in this most appropriate temperature, ie in the most appropriate distance from the beginning of the feed end of the degassing compartments, deduct the distillation products of, if, as drawn in Fig. 15 and 16, by the piston of Beschickapparates pipes R in this Introduces the side of the degassing spaces, which are combined in the manifold R ¹ .

The tubes R can all be introduced into the same distance from the beginning of the degassing space, or a part of these tubes R can be inserted less deeply into the degassing space, and these can be combined in a collecting tube R ¹ and thereby mainly the distillation products which develop first ( Water and tar) to condensation apparatus.

At the same time, other tubes R ² can be inserted deeper into the degassing spaces and through

Claims (4)

with the aid of another collecting pipe R ^s, the distillation products (oils, ammonia, etc.) which develop later are conveyed into the same or to a special condensation device. So is through the so constructed gas catches for degassing rooms with continuous operations a total or a portion of the various distillation products this enables. In the described device of the gas traps for degassing rooms with continuous operations, a single piston is assumed for the charging apparatus, through which the tubes R pass. In the case of the fig. 17, 18 and 19 are the device shown; several flasks K arranged in the charging apparatus, between which the tubes R, passing through, discharge the distillation products to the side. The tubes R can, as shown, be divided into two parts by a partition s, Fig. 19, of which one part, which into the tube? ¹ , Figs. 18 and 19, opens, less far., The other part, which into the tube i? ² opens, penetrates further into the degassing space, so that a partial recovery of the distillation products is also possible in this way. The tubes R ¹ and R ^{2 of} the various adjacent degassing spaces open into the main collecting pipes G respectively. G ¹ , which lead to the condensation apparatus. In addition, condensation apparatus with overflow can be arranged under the tubes. All tubes R 'and R ² can be closed off from the main collecting pipes G and G ¹ by flaps, slides, valves or the like in order to switch off the individual degassing spaces. . In general, these gas traps can be provided with all the known devices, which appear necessary to secure operations. This facility also permits total or partial extraction of the distillation products. 2. Gas interception by vertical, introduced from above through the vault into the degassing space Tubes. In Figs. 20 to 23, a Gasabfang is drawn, in which the vertical tubes RR ¹ R ² absorb the distillation products of from the degassing through the shafts .S .S ¹ S ^'2 and the main pipe G, Fig. 20, or in Guide main pipes GG ¹ C , Fig. 21 and 23. From here the distillation products get into common condensation apparatus, Fig. 20, or in various condensation apparatus, Figs. 22 and 23. So it is through this arrangement enables a total or a partial recovery of the distillation products. Patent claims: 1.
