Method and device for processing oil shale and the like. Patented in the German Empire on August 25, 1925.

That you can get through from pressed oil shale

successive smoldering, gasifying, burning and cooling a porous light Can produce block is assumed to be known.

In order to be able to carry out this process in practice, it has been proposed that Pressed items on platform trolleys in a lattice-like stacking through a closed one Passing through the duct furnace and the thermal treatment in differentiated heated Zones to make. It will be at

This process, however, gained a useful component, but in continuous operation it is not possible to obtain the distillates completely and undecomposed. The individual zones must also be separated from each other by tight doors, each time Operation when inserting a new car the operation of the furnace naturally extremely complicated.

The present invention eliminates those mentioned Evil conditions due to a new structure of the Schwelgood in the form of a latticework retort. Fig. Ι shows this in perspective. The latticework retort is made of a lattice core 1 and a dense retort jacket 2 formed, which according to the invention from the same pressed Individual pieces is built up and the lattice core 1 like a hollow jacket on all sides sealing i tend to enclose. The tightness of this hollow | mantels is achieved by the Sides of the pressed part, which form the bed and butt joints, with coal sludge beforehand

or the like slightly moistened.

The distillates are sucked down in a manner known per se, and experience has shown that the best results are achieved. As tests have shown, this method is around 80 percent the theoretical yield.

The new process can be carried out both in the channel furnace and in the ring furnace will. When the process is carried out in the sewer furnace, the distillation gases are extracted made in a known manner through the chassis downwards. The latticework retorts are useful in this particular case above |

covered with iron lids, which in the! Burning zone can be lifted off. This will; made it possible to make the burning process better! to monitor and the temperature by i to regulate coals thrown in above. :

Fig. 2 shows a ring furnace of known type, in which, in place of the usual _{(conventional} simple stacking, enter latticework retorts. These are advantageously constructed on the sole 4 of the ring furnace in a plurality of rows 3 side by side, then forming spaces resulting heating channels in which vorwandert the fire in the at! Ringofen usual manner steadily. 1 the distillates formed are also derived by j out below. For this purpose are used in the furnace bottom 4 j j debouching distillation gas discharge tubes 5, which with the interposition ■

processing of shut-off valves 6 with one or more distillation gas collecting receivers 7 are connected, which are arranged below the furnace base 60 in the access channel. Around to spare the upper, more difficult to manufacture covers of the latticework retorts, you can also lead its side walls up to the furnace ceiling and compress it with it. " Given the possibility of digging holes 8, which break through the furnace roof, in to get inside the retorts and to regulate the firing process. The required 7 ° Combustion air can, if in the course of the firing process, the retort wall becomes porous does not penetrate sufficiently, also introduced 75 through the gas discharge pipes 5 into the interior of the lattice retort will.

Claims (4)

Patent claims: 1. Process for processing oil shale and similar materials successive smoldering, gasifying, burning and cooling of pressed oil shale pieces in one operation for the purpose of obtaining distillates and building blocks, characterized in that the Pressings in a manner known per se lattice-like, with gaps above and next to one another, stacked and divided Quantities of thin-walled retorts built up from the same pressed individual pieces like a hollow jacket on all sides be enclosed in a sealing manner. 2. Implementation of the method according to claim 1 in a ring furnace, characterized characterized in that the latticework retorts in several with the side furnace walls and with each other heating channels forming rows are built in the ring furnace channel. 3. Modified structure of the feed in the ring furnace according to claims 1 and 2, characterized in that the side walls of the lattice retorts to to the furnace roof and compacted with this. 4. Ring furnace for performing the method according to claim 1 to 3, characterized characterized in that one or more distillation gas collecting reservoirs are arranged below the furnace base in the access channel are, which by individually lockable or adjustable, downpipes opening into the furnace base with the latticework retorts stay in contact. 1 sheet of drawings.
