Wire cleaning equipment

The invention "relates to a device for disposal of the vinyl overlay (vinyl = 1 value CH residue) of waste wires (Scrap) from the electrical wire and cable industry and wires in general from the wire processing industry Electrical industry.

As is known, these waste wires are used for the purpose of prizes the copper soul burned down. The wires, which have recently been covered with vinyl, pollute the city air because they generate smoke that contains hydrochloric and other harmful gases.

The invention now consists in an apparatus which prevents this. Another characteristic is that the copper elements can be exposed without oxidation.

With the device according to the invention, vinyl-coated Wires are distilled dry in a closed container and the gas is de-wilted in the process Condensate and water-soluble substances removed by means of an air-cooled pipe and a few water baths.

The residual gas and combustible condensate are fed to the distillation furnace as fuel.

The accompanying drawing shows, for example, in

Pig. 1 in a schematic vertical section from the Seen from the side, the device according to the invention.

^ ig. & represents the top view of 5 ¹ Ig. 1 represents.

This cleaning system has a number of long steel dry distillation ovens 3, the ends of which are equipped with closure lids 2 on puddles 1. The tubes 3 are inserted inclined in the furnace 4, with their ends protruding from the furnace 4 and in the masonry 4! and 4 ^f 'are supported. The upper end of each distillation furnace tube 3 has a discharge line 5, which in turn is connected to an air cooling rod 9, the lower open end of which protrudes into a condenser tank 1o. The same vent line 11 is immersed in a water bath 12 and a line 13 extending from the container 12 is immersed in a further water bath 14 which is surrounded by a cooling jacket 15. From the water bath 14, a discharge line 16 goes off; it leads to the fire grate 7 of the kiln 4. This has a chimney 8.

The subject of the invention works as follows:

First, a batch of scrap wires is inserted into the steel, dry stills 3 inserted after

the upper flange cover 2 has been removed; he must then reconnected. The fuel in the furnace 4 on the grate 7 is then ignited - ^ in the furnace tube chambers 3 This combustion then turns the vinyl jacket into the Copper wires decompose and a certain type of gas is produced that travels through line 5 and through the cooling coil 9 flows. The condensate (tar) that forms in the air cooling coil 9 is collected in the condenser tank 1o and collected, laugh at this condensation run The gas stream reaches the first water bath 12, in which salt gas and phthalic acid are condensed. Through this the water temperature rises and the water becomes milky. However, a large part of the hydrochloride gas is not dissolved in the high-temperature water 12 and is fed to the second water bath 14, where it is completely in a water cooled to 40 ° C. by the cooling jacket 15 is dissolved. In contrast, the phthalic acid is sufficient in the Water bath 12 at a higher temperature condenses, precipitates, emulsifies. As an aside, when refrigerated, phthalic acid turns itself settle in the tube immersed in the water bath 12. The end gas product from the second water bath 14 does not contain any water-containing, condensable or soluble components, such as tar or hydrochloric substances, i.e. it is a non-condensable gas. Because it however, if it is flammable, this end product becomes the fire pit 7 of the furnace 4 as fuel through the Eohr 16

forwarded. The tar accumulated in the tank 1o becomes the Furnace also fed as fuel? it does not contain any harmful flowing hydrochloric gases!

From the second water bath 14 the accumulating (HOL) Hydrochloric acid is removed by a suitable, "known method. The same applies to that contained in the water bath 12 usable chemical substances.

The gas which is formed during the cleaning process of the wires to remove the vinyl coating is therefore according to the invention broken down into usable components, without any harmful, air polluting components, gases, ins Get prices.

As a result of this dry distillation, the treatment of the wires in the furnace 3 », the copper gets its original good quality Shimmer (luster), as it was not during the treatment oxidizes, while the ashes of vinyl are produced in the form of high-purity coal for various uses.

The apparatus of the invention is easy to use because vinyl-clad wires through the top opening 1,2 into the Dry distillation furnace tubes 3 are introduced, while the ash components and the copper at the lower end 1,2 same at 4! can be removed. The tubes 3 consist e.g. made of gas pipe material that is as corrosion-free as possible.

Claims (1)

Is provided that arranged for this material a conclave tube (3) in a kiln (4) 1- means for freeing viny! Coated drop-wires of this ^ü Plating, characterized in that said irockendestillierrohr (3) via a line "(5 ) and a cooling air coil (9) is connected to a condenser (1ο), to which a gas line (11) is connected, which leads to a first water bath (12) to which a water bath (14) is connected via a line (13) and to this a gas discharge line (16), which in turn is connected to the furnace (4) or its furnace (grate 7). 2. Device according to claim 1, characterized in that it has a number of rock distillation furnace tubes (3), their both sneezes on paddles (1) have cover plates (2) releasably and wherein the tubes (3) in the furnace (4) are arranged at an incline and with their ends on both sides of the masonry (4 ', 4 ") protrude, which it carries and supports at the same time and the vinyl-covered waste wires or the like find a suitable way in the tubes (3) inclusion.
