Definitions

  • the invention has for its object to carry out the introduction of hydrogenation residues in a carburetor so that the aforementioned difficulties are avoided.
  • the hydrogenation residues it should be possible to introduce them into a carburetor in such a way that the necessary supply lines and associated devices remain operational.
  • the means used for this should be simple and less prone to failure.
  • the invention proposes that the finely ground residues are conveyed through a cooling section into the carburetor with the aid of a conveying gas.
  • a grain size is obtained which is particularly suitable for gasification in gasification reactors of the type mentioned.
  • the finely ground residues can be stored in storage containers of the usual type without difficulty and special effort over longer periods and in sufficient quantities.
  • the conveyance with the aid of a conveying gas from the storage container has, in addition to the transport effect, also the advantage of a certain, albeit limited, cooling effect.
  • the conveying gas When flowing through the cooling section, the conveying gas ensures a good swirling of the residues up to the immediate vicinity of the feed into the gasification reactor, which ensures that the cooling along the cooling section essentially covers all residue particles evenly, so that caking and sticking of the pipelines are avoided.
  • grinding the residues to grain sizes below 2 mm has proven to be particularly suitable.
  • the cooling section is advantageously designed as a water cooling system.
  • the inlet of the cooling water is conveniently located near the gasification reactor, while the outlet should be located at the end of the cooling section facing away from it.
  • the cooling section advantageously surrounds the supply line for the residues over its entire circumference and extends at least to the vicinity of the outer wall of the reactor, if not through its insulating jacket, at least as far as the inner wall thereof.
  • This configuration of the cooling section ensures that the softening temperature of the residues before they occur in their area where this is no longer harmful is not exceeded and the cooling of the residues takes place to some extent evenly. In this way it can be achieved without great effort that the feed lines do not stick together and are not added.
  • a major advantage of the invention is that the cooling device can be retrofitted to existing gasification devices without difficulty.
  • the gasification process is also regulated with regard to the product gas generated.
  • nitrogen (N 2 ) or carbon dioxide (C0 2 ) or air can be used as the conveying gas, these gases possibly also participating in the gasification reaction insofar as they, such as carbon dioxide and air, are of their chemical nature are suitable here.
  • the amount of the required conveying gas is small in comparison to the gas throughputs in the fluidized bed and does not interfere with the processes in the gasification reactor. In any case, it can be dosed so precisely with simple means that, on the one hand, the flow rate can be maintained and, on the other hand, undesirable influences on the processes in the gasification reactor can be excluded with certainty.
  • the entry point for. B. inclination to the horizontal and / or tangential blowing, immediate mixing of the hydrogenation residues can be achieved with the reaction material present in the gasifier.
  • cooling section is designed as water cooling has proven to be very simple and less susceptible to faults. The latter enables the temperature in the interior of the cooling section to be regulated very simply as long as the water is kept below the evaporation temperature. In addition, water cooling offers the well-known advantages of great operational reliability with simple handling.
  • the reservoir for the residues is expediently provided with a shut-off device at its outlet, so that the residues can be fed to the gasification process in the gasification reactor in a simple manner depending on the respective absorption capacity of the same and other factors to be taken into account.
  • the gasification reactor has an essentially cylindrical housing 1, through which gasification agent flows from bottom to top in the direction of arrows 2 and 2, that is to say in the direction of its longitudinal axis.
  • gasification agent flows from bottom to top in the direction of arrows 2 and 2, that is to say in the direction of its longitudinal axis.
  • this will essentially be oxygen-containing gases, steam and carbon dioxide, and in the case of an HKV reactor, it will mainly be hydrogen.
  • the gasification of the carbon-containing materials takes place within a fluidized bed 4 and a downstream post-reaction space 14.
  • a feed line 5 for the hydrogenation residues 6 enters laterally into the gasifier 1.
  • the latter are stored in a storage container 7 in finely ground form and fed into the feed line 5 via a shut-off element 8.
  • the supply line 5 acted upon by a conveying gas in the direction of arrow 9, which detects the residues below the point of application of the shut-off element 8 and conveys it through a cooling section 10 into the gasification reactor 1.
  • the cooling section 10 extends in the immediate vicinity of the carburetor 1 and has two connections 11 and 12 via which the cooling water is fed in or out. It surrounds the supply line 5 on all sides, which in turn also has a shut-off and throttle element (not shown) for the conveying gas 9.
  • the length of the cooling section is at least 5 times, at most 20 times, preferably 10 times. It is particularly advantageous to arrange the connection 11 for the cooling water in the vicinity of the housing of the reactor 1, while the connection 12 for the return of the cooling water is provided on the side facing away from the reactor. It is thereby achieved that the residues 6 conveyed in the feed line 5 are heated uniformly and not too strongly.
  • the cooling water throughput depends on the volume of the cooling section and on the temperature of the reactor 1 and the amount of the residues 6 which are conveyed.
  • the cooling water supply and temperature maintenance are regulated by conventional organs.
