52 0 all whom it may concern;

Be it known that 1, Ashton!) Monr'rnmga citizen of Switzerland, residing at Oherwinterthur, Switzerland. Alto have invented certain new and useful improvements in Containers for the Dry Cooling of Coke, of which the following: is a specification. i

The present invention relates to a container for the dry-coolin of coke by means of cooling gases passed through the charge of coke, and consists in the cooling gases heingintroduccd into the charge of coke from apoint which is situated over the discharge opening of the container. For introducing the cooling gases into the charge of coke an inner structure can he arranged. The inner structure is with advantage so situated that the charge of coke, with respect to the introduction of the cooling gases.- is divided into different zones one over the other. each of which all parts of the charge of coke must pass through -and be directly acted onby the cooling gases before reaching the lower part of the container. The inner structure can have several openings arranged in it one over the other and he so designed that a part of the cooling gases are directed downwards. A separate piping may be rovided for directing them downwards. The cooling gases introduced can be distributed in such away that a part of them is introduced at the lower end of the container into the charge of coke.

The piping for the cooling gases leading to the inner structure and the piping for the cooling gases leading to the lower end of the container can be fitted with regulating devices by which the ratio of the amount of cooling gas introduced to the inner structure and the amount introduced to the lower end of the container may be altered. These regulating devices may consist of simple dampers. Two constructions of the object of the present invention are shown in section in the drawin s oi which"- Fig. l is i: vertical section of the container showing the charge of coke in situ. and

Fig. 2 is a diagrammatic ,view of a part of the same section. showing the Zones into which the cooiino coke is divided.

In 1, a is the colre container. 5 the charge of coke, c the filling opening, and oi Romerstrasse 21,

the piping ior introducing the cooling gases. 6 is a space arranged in the lower end of the container and from it a part of the cooling gases can he introduced into the charge of coke. f is the outlet for the cooling gasesand g a. conveyor-belt moving in -the direction of the arrows as drawn; by means of this belt the coke can be delivered through the door h to the opeh air. i

The inner structure 2', arranged above the and from w ich the cooling gasesare introduced into the charge of coke, is fitted with openings Z. and connected with the cooling-gas delivery pipe d by means of the pipe Z. l The structure 7: is fitted with a pipe 'm directed downwards, and through this pipe a part of the cooling gases can he conducted downwards. The devices by means of which the introduction of the cooling gases to the space 0 and to the structure 2' or the "pipe m is regulated. are indicated by 1?. and p. The, device 7? is so designed that it controls the amount of cooligig gas delivered to the structure 11 as welt-as the smountto the he purpose of the invention is to distribute the cooling gases introduced to the charge oi coke in such a way that a uniform. cooling of all parts of the charge of colic is attained. The diiliculty in charging the container consists mainly in the fine coke collecting in the centr of the container whilst the large coke rolls down the siope formed by the upper surface of the char e of coke and collects near the walls of t e container. The density of the charge oi coke is therefore not uniform, i. c... it decreases towards the outside and therefore makes it. possible for the cooling gases, which take the pathoi least resistance, to flow along the walls of the container straight to the outiet. The charge of coke is therefore cooled oniy on the outside and not in the centre, 5.. e., oniy a small part of the heat contained in thecoire is led away and the purpose of the whole installation is not attained. I

The process of cooling according to the present invention works as follows:

The cooling oases reach the container (2 through the pipe (2 and flow. when the damper n is closed, through the pipe E into the structure 5., which is hollow. lhrough the openings ii: the gases -force their way into oi. the charge v incense the charge of coke, pass upwards through it, and escape by the outlet f. The coke enters the container through thefillinw opening 0 and leaves it at the lower end? Where it can be delivered to the open air through the door it'll} means of the conveyor-belt g.

If a part of the cooling gases is to be introduced into the charge of coke at the lower end of the container, the damper n is opened. The 'cooling gases then flow partly into the side/cc e, from. where they can be introduced into the charge of coke. If a part of the cooling gases led to the structure i is to be directed downwards, the damper p is brought into the position shown in the drawing. From the pipe m, which can be open or closed at the lower end, the gases then (scape through the opening is.

If the. pipe in is to be closed, i is only V necessary to turn we damper p downwards.

The arrangement is such that all parts of coke, before reaching the lower part of the container, must traverse the .zones which are directlyacted on by the cooling gases. The charge of COlt'G can therefore be considered as divided into .different zones as shown diagrammatically in Fig. 2. The lowest zone correspending to the height fi contains the coke which has been cooled: the cooling gases act directly on the zone h which therefore is more intensively cooled than the zone in, Which contains the hot coke last introduced. The movement of the layers of coke adjusts itself automatically, thereby assuring in the best manner that no part of the charge of coke leaves his container Without having been thoroughly cooled.

The advantage of the container consistsi the possioility of giving the structure 11 with its openings 0 such a form and size, that the cooling gases can be introduced into the lower and upper, as well as into the outside and centrsl ports of the charge of coke, thus allowing an absolutely uniform cooling of the whole charge of coke to be atteined. The Work in connection with charging and discharging the container will not be disturbed in any Way by the inner structure and the pipe leading to itimm the side.

2. In an apparatus tor cooling incandescent colts by means of gases forced through the charge of echo as it passes through a. container, the combination of a container, a distributor built into the container, a series of outlet openings inthe distributor spaced so as to cause cooling gases issuing through them to produce a cooling zone of a predetermined depth and means for introducing cooling gases through a distributor into the charge of coke.
