Carbonization gas converter

The invention relates to a carbonization gas converter for changing, cleaning and cracking carbonization gas, thus the carbonization gas becomes phenol-free gas, which is problem-free and environmentally friendly in engines, turbines and for heating purposes can be used.

The carbonization gas is swirled with air and ignited. Before this mixture meets the glowing coke, it has an even and optimal temperature in the flame tube achieved. As a result, no high-temperature zones are formed in the coke bed, in which the formation of varnish is inevitable were.

In the coke bed takes place at the constant temperature of approx. looo to 13oo C ,. as the circumstances require, the cracking of long-chain hydrocarbons and chlorinated carbon-hydrogen compounds. The clean gas is cooled and washed before use.

The smoldering gas wall known since then (he still have large Disadvantages, especially when the atmospheric oxygen meets with the carbonization gases in the area of the coke bed without mixing, reaches a high local temperature and slag forms. This slag formation is increased when the carbonization gas and the air move from above is passed down through the reaction coal bed. This causes the coke slag and the sintered dusts of the carbonization gas deposits are formed, which increasingly the

Clog the bed of coke.

When the carbonization gas and the air hit the surface of the coke bed an enamel-like slag cake is created, which interrupts the reaction of the reactor. I am also not aware of any system in which the coke residues can be easily discharged, in particular discharge devices that are permanently located in or directly under the coke bed cannot be implemented satisfactorily,

The present invention overcomes all deficiencies in the gas converter since then by means of a completely new concept which:

- There are no moving parts in or on the coke bed at all times.

- Furthermore, the mixing of carbonization gas and air no longer takes place in or on the coke bed, but together with controlled turbulence in a separate flame tube.

- The coke residues are pushed into a discharge trough by a pusher as required. The slide is on chains attached and remains outside the area of the glowing coal bed after it has been pushed out. He is but still in a housing sealed from the outside air.

- The greatest heat is created below, because the carbonization gas-air mixture is guided from bottom to top. Any slagging that occurs only on the underside of the Coke beds can be easily removed from the hi-3r will.

An exemplary embodiment is described below in the drawings.

Instead of carbonisation gas as is the case with waste carbonisation, for example arises, any other type of gas can also be treated in the carbonization gas converter described, if this makes sense.

The carbonization gas converter is constructed as follows: The reaction vessel 1 with lining 17 is on the Scraper box 2 put on, which stands on feet. The flame tube 3 hangs in the reaction vessel 1. The mixing chamber with mixing nozzle 5 is attached to the upper end of the flame tube 3.

The coke bed 6 is located in the reaction vessel and its fill level is monitored by the fill level monitor 7 and the coke supply unit 8 is controlled. The level level of the coke bed 6 is reached by means of the planar plates 9, which are attached to the perforated plate 15 are attached. The perforated plate 15 is driven by the motor with gear Io.

In the scratch box 2 there is e ^ in chain circulation train 11, which pulls the scraper 12 over the grate plate 13 if necessary.

The discharged ash falls into the shaft 14, at the end of which there is a water bath discharge screw. After the carbonization gas-air mixture flowing in through the flame tube 3 flows through the coke bed 6 from bottom to top it finds its way through the holes in perforated plate 15 as cracked gas. The cleaned one is then cleaned Gas withdrawn through tube 16.
