Definitions
- the invention relates to a furnace and rotten furnace, in particular dusts from vend basins, with asbestos, with a melt and a blanket arranged above it, with a length and with a device for the n. 15 to be melted above Ele. protruding into the melt
- a simple object of the invention is to produce the n furnace of one type and with little effort, with a small number of gears mentioned, This object is achieved in the oven mentioned at the outset by the fact that its basin is embedded in the ground. In this way, an extremely simple and inexpensive furnace construction is achieved.
- At least the basin walls can advantageously consist of a protective layer. This is particularly useful if the ground does not already consist of a hard-melting natural rock.
- FIG. 1 shows a furnace in a first embodiment in vertical section
- Figure 2 shows the oven in a second embodiment also in vertical section.
- the furnace consists of a basin 1 excavated on a suitable site and embedded in the ground 3.
- This basin 1 is lined with a protective layer 2 of refractory concrete on the side walls and in the lower horizontal part.
- a protective layer 2 of refractory concrete
- hard-melting natural rock such as granite or the like
- the basin 1 can also be surrounded only by a foundation 2a for the structures.
- the outline shape of the basin 1 is preferably round or polygonal.
- the basin 1 has a simple sheet steel hood 5 as the ceiling, the foundation in the form of a fire-concrete strip 2a forming the support for the hood 5 at the edge of the basin.
- an inner tube 6 is attached, to which an input tube 7 is attached telescopically, which is adjustable in height by an adjusting rod 8 in the center of the tubes 6, 7.
- a screw conveyor 9 opens at the top, with which the batch to be melted is conveyed from a bunker 10 into the furnace.
- the hood 5 also has an exhaust pipe 11, which leads to a flue gas cleaning system, not shown.
- the hood 5 has concentrically arranged, angularly adjustable electrode bushings 12 through which electrodes 13 are inserted into the interior of the basin 1 and into a melt 14 located therein.
- the electrodes 13 are supplied with electrical energy from a furnace transformer in the usual manner and can be extended and replenished if necessary.
- the batch is introduced into the inner tube 6 via the screw 9, falls downward and forms a batch blanket 18 floating on the melt 14.
- the lower end of the input tube 7 is adjusted in height so that the natural slope angle of the batch is completely covered the surface of the melt 14 leads within the basin 1.
- a ring line 19 is installed at the upper end of the hood 5, which is equipped with nozzles, so that the hood 5 can be cooled from above with water if necessary.
- the amount of water can be such that the water evaporates before it reaches the lower part of the hood 5, whereby the temperature of the metal forming the hood 5 can be kept just above 100 ° C.
- the protective layer 2 may leak during operation of the furnace.
- the melt will solidify and thereby seal itself at the latest in the cool environment of the basin 1, so that no further erosion of the ground 3 can then be expected. Repair work is therefore not necessary.
- Basin 1 solidifies into a solid vitreous body that remains in place. Since the vitreous body is largely resistant to chemical attacks, the vitreous body can be left in the ground without any risk to the environment and groundwater.
- the relatively light hood 5 with the devices 6, 7, 8, 9, 10 for the batch feed can be dismantled very quickly after the basin 1 has completely melted and can be reassembled at another location, so that the furnace is particularly suitable for soil remedial measures can follow the progress of the work.
- the furnace shown here also consists of a basin 1 lying in the ground 3.
- This basin. 1 is here only lined with a protective layer 2 of fire concrete on the side walls.
- a circular arc which is preferably at a distance of approximately 1 m from the inner edge of the basin 1, holes approximately 2 m deep are drilled into which cooling tubes 4 are inserted.
- These cooling tubes 4 are charged with water and are preferably connected in series. They serve to cool the ground 3 in the vicinity of the basin 1 in order to prevent the ground 3 from melting.
- the basin 1 also has a sheet steel hood 5, the aboveground ends of the cooling pipes 4 serving as abutments for the hood 5, and a fire-reinforced concrete strip 2a forming the support for the hood 5 at the pool edge.
- the hood 5 and the parts 6 to 13 arranged thereon correspond to those of the exemplary embodiment according to FIG. 1, and reference is made to the description given there.
- the furnace according to FIG. 2 also has a melt 14 removed
- the outlet is formed by a passage 15 and a riser 16 which merges into an overflow 17.
- the riser 16 is heated by an immersion electrode 13 'which is electrically connected to one of the electrodes 13 in the basin 1.
- cooling pipes 4 ′ are installed on all outer sides of the riser.
- the melt that is drawn off runs over the overflow 17 onto a plate belt 20 and is conveyed upwards by the latter.
- the melt solidifies into small glass bodies that e.g. are reusable as ballast or concrete aggregate.
- a second outlet can be provided as a simple branch channel at the level of the surface of the melt 14 either parallel to the melt overflow 17 or at another location in the basin 1.
- the protective layer 2 may leak over time if it runs for a long time.
- the melt solidifies at the latest in the vicinity of the cooling pipes 4, so that no further erosion of the ground 3 can then be expected. This means that repair work is only necessary at the outlet.
