Definitions

  • the invention relates to a method and a plant for energy production by garbage gasification according to the preamble of claim 1 and of claim 6.
  • US Pat. No. 3,817,724 discloses a waste gasification process which involves incineration of the solid residues and in which the crude gas is washed with a mixture of fresh water, alkali carbonate and a recycled portion of the dust-laden and condensate-laden cleaning liquid. Stripped solids are recycled as sludge into the gasifier along with a small portion of the cleaning liquid, while a small flow of oil and purified raw gas are burned to produce electrical energy. In addition, a portion of the raw gas is burned with air or oxygen and the resulting hot combustion gas is fed into the gasifier.
  • the object of the invention is to provide a method and an installation of the type mentioned above, by which a maximum of useful energy is obtained, with optimal prevention of contaminated wastewater and exhaust gases.
  • the withdrawn from the melt gasifier hot raw gases are supplied to a hot gas steam generator in which the hot gas steam mixed and this hot gas-steam mixture is passed through the double turbine rotor of a turbine which drives a power generator, at the same time takes place a pre-reaction.
  • the pre-cleaned hot gas-vapor mixture is introduced into a falling-stream device in which, using injected lye-added water and repeated expansion and compression with foaming, the mixture is cooled and pre-cleaned, the pre-purified gas being drawn off and the liquid collected becomes.
  • the material to be gasified slides downwards in the guide cylinder, while the released gases flow upwards in the gas guide channel and also exit radially through the openings.
  • the sinking gasifying and melting mass is no longer in contact with the carburetor housing shell, so that damage is avoided and also a blocking of the refuse is prevented.
  • the resulting gases have the ability to either climb high in the gasifying material or excrete to a greater extent radially in the annular guide channel and then flow directly undisturbed upwards. This makes it possible for the gases which have already been outgassed at 60 ° C.
  • a vapor-gas mixture forms in the upper area, which is not explosive and can be sucked off by the vacuum present in the discharge pipe.
  • Another advantage is that in the method according to the invention for operating a generator by a double turbine runner, from the gasifier (melt gasifier) obtained a garbage hot gas, upstream of the turbine, ie immediately before the turbine inlet water vapor (high-pressure steam) is introduced or generated, in such a way that this steam enters the turbine immediately upstream of the turbine inlet at high pressure, together with the hot gas and at the same time mixing with it.
  • This hot gas / vapor mixture is then mixed at very high density and high speed with the turbine tapering in relation to the last section of the gas inlet. introduced, after which this mixture is first expanded on the double rotor of the turbine and then compressed again, whereby a total of a pre-reaction takes place in the mixture.
  • the hot gas-vapor mixture from the one small diameter portion, similar to that at the entrance of the housing opening, in an expanding diffusion portion of the subsequent drain pipe, after which the mixture expands again, while in the drain pipe, a negative pressure prevails.
  • HGDG hot gas steam generator
  • Another advantage is that for the production of high-pressure steam purified and thus lime-free process water is introduced centrally into the turbine inlet, the z. B. is supplied from the water purification device of the waste recycling plant.
  • This lime-free water is vaporized by the hot gas, after which hot and raw gases are mixed with the water vapor and brought into pre-reaction.
  • This can advantageously take place in that the water is introduced into a concentrically in the balloon-like extended inlet, pear-shaped opening to the turbine inlet high-pressure vessel, which is surrounded by hot gas.
  • the resulting in the container high-pressure steam exits at high speed near the turbine inlet, mixes with the outside flowing past him hot gas and enters at high speed in the turbine, in further mixing of the hot gas with the water vapor and thereby taking place pre-reaction.
  • the driven by the energy of the hot gas-steam mixture turbine then further drives the generator via its drive shaft, preferably a permanent magnet generator.
  • This generator can preferably be multi-stage be formed, ie for different torques, according to switchable or switchable, according to the torque received from the turbine.
  • the direct current generated by the generator is preferably used inter alia for physical separation with electrolytic decomposition of the contaminated water (process water) of a waste recycling plant.
  • the excess oxygen and hydrogen thus generated is used for further use in the system, preferably fed to the auxiliary burner of the carburettor or to an internal combustion engine for the corresponding generation of useful energy (increase in the primary energy).
  • a part of the generator current to supply the system eg. B. of their pumps serve.
  • the decreasing gasifying and melting mass is no longer in contact with the carburetor housing shell, so that its damage is avoided and also a blocking of the refuse is prevented.
  • the resulting gases have the ability to ascend either in the gasifying material or exiting to a greater extent radially in the guide channel and then flow directly undisturbed upward.
  • the radial openings of the guide cylinder have roof-shaped pushed out covers, z. B. inclined at an angle of about 5 ° to 20 °.
  • These covered openings can be formed by introducing arcuate cuts in the cylinder jacket, which are then slightly pushed out or bent inwards. As a result, a roof is present over the resulting opening, so that the opening is protected from the sinking material and at the same time an outflow help for the gases is formed.
  • the guide cylinder ends at its upper end over the edge of the hot gas discharge pipe, preferably approximately in the middle.
  • the upper edge of the guide cylinder may have a conical enlargement, so that this edge is radially substantially up to the housing shell. This avoids that top-up material penetrates into the annular gas guide channel, causing damage and makes the gas outflow difficult.
  • a balloon-shaped or pear-shaped housing is connected upstream or between the turbine inlet and inlet pipe in comparison to the inlet pipe and the turbine inlet balloon-shaped or pear-shaped extended housing is interposed.
  • a substantially pear-shaped high-pressure container is concentrically arranged so that it faces with its narrowed outlet opening to the turbine inlet and is in its immediate vicinity.
  • the high pressure container is connected to a water inlet, said water inlet preferably opens centrally / axially into the container.
  • the hot gases surrounding the high-pressure container externally heat the container accordingly, as a result of which the water introduced into the container evaporates explosively and this steam enters the immediately succeeding turbine opening with a corresponding high pressure from the high-pressure vessel.

Les gaz bruts chauds extraits du gazéificateur par fusion (15) sont introduits dans un générateur à gaz chaud et vapeur (18) dans lequel de la vapeur d'eau est mélangée au gaz chaud, et ce mélange de gaz chaud et de vapeur est guidé par l'intermédiaire de la roue motrice de turbine double (18.13) d'une turbine (18.3) qui entraîne un générateur de courant (18.4), une réaction préliminaire ayant lieu simultanément. Le mélange de vapeur et de gaz chaud prépurifié est ensuite introduit dans un appareil à courant descendant (38) dans lequel le mélange est refroidi et prépurifié au moyen d'eau pulvérisée à laquelle est mélangé un réactif et par dilatations et compressions répétées du mélange avec moussages, le gaz prépurifié étant extrait et le liquide collecté. Ledit gaz prépurifié est introduit dans un étage de purification de gaz (40) dans lequel le gaz est moussé avec un réactif puis à nouveau démoussé. Enfin, les gaz purifiés subissent une valorisation énergétique ultérieure, par exemple par combustion dans un moteur (41).
