Definitions

  • the invention relates to a gas converter for carbonization gases from a pyrolysis of waste materials, consisting of a combustion chamber for a substoichiometric combustion of the carbonization gases with the supply of oxygen-containing gases, a vertical chamber with a bed of glowing solid bodies, a feed line for the hot, substoichiometrically burned carbonization gases Chamber, a discharge for the gases from the chamber after passing through the bed of the solid body, an addition device for the solids into the chamber and an outlet device for solids from the chamber.
  • One method is that carbonization of the waste materials at temperatures of approximately 300-800 ° C. produces carbonization gases and a solid carbonization residue.
  • the smoldering gases are then cracked at higher temperatures of around 850 - 1 200 ° C. This is done by sub-stoichiometric partial combustion with the supply of oxygen-containing gases and passage of the gases through a glowing bed of solids. After cleaning, the cracked gases are used as fuel gases.
  • EP-A-0 026 450 also refers to such a gas converter.
  • carbon dioxide gas entering the gas converter even if it is first passed through a mechanical gas cleaner, for example a cyclone separator, contains even larger amounts of dust particles. These are deposited in the bed of F eststoff emotionsn, and thread as a result of higher temperatures in the gas converter to caking and clumping. This prevents even and optimal gas passage.
  • a mechanical gas cleaner for example a cyclone separator
  • the invention has for its object to provide a gas converter which enables the most uniform and optimal gas passage through the bed of solids with the least possible effort.
  • the combustion chamber for the substoichiometric combustion of the carbonization gas is arranged horizontally, the feed line from the combustion chamber opens laterally into the upper part of the vertical chamber, the vertical chamber is tapered downwards, the discharge for the gases after the passage through the upper part of the bed of glowing solid bodies is arranged in the upper part of the chamber, solid bodies are continuously withdrawn from the outlet device of the chamber and fresh solid bodies are constantly introduced into the addition device of the chamber.
  • the upper part of the bed of solid bodies through which the hot, partially burned smoldering gases flow is selected so that the desired conversion of the gases is achieved. The size required for this depends on the composition of the carbonization gases gig and can be determined empirically.
  • solid bodies are to be understood as meaning both removed and cleaned solid bodies and new solid bodies. New solid bodies are preferably only added in an amount which corresponds to the consumption by abrasion and undersize removed.
  • the solid bodies are heated by the hot, partially burned carbonization gases. Even when coke or other carbon-containing materials are used as solid bodies, there is practically no combustion, especially because the partially burned carbonization gases do not contain any free oxygen.
  • a preferred embodiment is that the vertical chamber is designed with a round cross section. This ensures that the bed drops automatically and evenly.
  • a preferred embodiment is that the mouth of the feed line of the combustion chamber in the upper part of the vertical chamber is designed as an annular channel and the discharge for the gas is arranged in the ceiling of the vertical chamber after passing through the upper part of the bed of the glowing solid body .
  • the outlet opening of the ring channel is arranged at a height of the chamber such that the bed of solid bodies above it has a sufficient height.
  • a preferred embodiment is that the mouth of the feed of the combustion chamber in the upper part of the vertical chamber on one side of the chamber and the discharge for the gas on the opposite side of the chamber are arranged, the solid body in the upper part of the chamber between two vertical gas-permeable walls are arranged, the gas-permeable vapors at a distance from each other are arranged, which is smaller than the diameter of the bed of the solid body in the adjoining part of the chamber and the gas-permeable walls extend over the cross section of the upper part of the chamber.
  • the height and thickness of the bed of the solid body between the two gas-permeable walls is chosen so that it is sufficient to convert the gas.
  • a preferred embodiment consists in that the outlet opening for the solid bodies is arranged in a water bath at the lower end of the vertical chamber. This results in a simple discharge with immediate cooling of the solid bodies.
  • the horizontal combustion chamber consists of the burner 1 and the combustion chamber 2. Preheated air 3 and carbonization gas 3a are passed into the burner 1 and partially burned under-stoichiometrically in the combustion chamber 2.
  • the supply line to the combustion chamber is designed as an annular channel 4 with nozzle stones 5.
  • the feed line is formed through the outlet opening of the combustion chamber 2.
  • the supply line 4, 4a opens into the upper part of the vertical chamber 6.
  • the chamber 6 has a round cross section and is designed to taper conically below the supply line 4, 4a.
  • the discharge 8 for gases after passage through the upper part of the bed 7 the solid body is arranged in Figure 1 in the ceiling of the chamber 6 and in Figure 2 opposite the feed line 4a.
  • the upper part of the bed 7 consists of the part which is located above the nozzle stones 5.
  • two gas-permeable walls 9, 9a are arranged in the upper part of the chamber 6, which extend over the entire cross section of the chamber 6.
  • the walls 9, 9a consist of grate bars which are attached to air-cooled tubes 10.
  • the space between the walls 9, 9a is filled by a bed 7a of the solid body, which is supported on the lower bed 7.
  • Solid bodies are continuously discharged from the outlet opening 11 of the chamber 6 via a water bath 12. Fresh solid bodies are fed through the addition device 13.
  • a support burner 14 is arranged in the combustion chamber 2 and is used to heat the solid bodies during commissioning, at standstill and when the composition of the carbonization gas fluctuates.
  • the advantages of the invention are that the structural design of the gas converter achieves considerable weight savings, the wear caused by the moving bed is kept low, the exchange of the solid bodies is carried out in a simple manner and the smoldering gases nevertheless constantly meet a bed of fresh solid bodies .
