Definitions

  • the invention relates to a method according to the preamble of the first Claim and an apparatus for performing the method.
  • the invention is applicable wherever there is a need for cooling and Cleaning of hot gasification gases, which are used in the gasification of combustion, Residual and waste materials arise.
  • Fuels such as coals of various degrees of carbonization, oils various volumes as well as gases such as natural gas, residues from the Industry such as synthesis residues, halogen-containing residues such as hydrocarbons containing chlorine or fuels, residues oil processing such as heavy oils and petroleum coke as well as waste materials Household and business such as halogen-containing plastics mixed with other waste.
  • the raw gas which is hot at temperatures between 1000 ° C and 1600 ° C, enters a cooling or quench system after the reaction chamber, where the gas is cooled and saturated by direct contact with water.
  • a group of technical solutions uses a tube which is cooled on the inside with a water film and which is immersed in a water bath, as described in DD-WP 145 860 and DE-OS 31 51 483.
  • This cooling principle is supplemented, among other things, by further cooling stages in the form of, for example, water atomization at the end of the dip tube.
  • a disadvantage of this principle is the high specific water consumption regardless of the performance of the reactor and the insufficient cooling and washing effect.
  • Spray quench systems have been used to overcome the disadvantages mentioned developed, in which the hot gasification gas as a free jet into one Free space occurs and the cooling is done by injecting water. Solutions of this type are described in DD 288 614 B3 and in DE 36 01 786 C2.
  • the invention is based, hot gasification gases, the task the gasification of fuels, residues and waste materials arise and with Temperatures of 1100 - 1600 ° C leave the gasification reactor through Contact with a coolant for a fall cooling (quenching) undergo and at the same time initiate a washing process.
  • the Cross-section of the Venturi tube depending on the amount of gas be regulated that always the optimal speed of the gas flow is set. Especially when extracting valuable materials from the Gasification gas such as hydrochloric acid or hydrofluoric acid such as this is possible when using halogen-containing residues and waste materials Venturi quench system downstream of further washing stages and in the cycle get connected.
  • Figure 1 shows the arrangement of gasification reactor 2 and Venturi quencher 3.
  • the fuel, waste or residual material is fed together with oxygen via burner 1 to gasification chamber 2 and converted in a flame reaction to CO and H 2 -rich gasification gas.
  • the 1100-1600 ° C hot gasification gas passes from the gasification chamber 2 into the Venturi quencher 3, in the narrowest cross-section of which the hot gasification gas to be cooled and cleaned is accelerated to speeds between 50 and 100 m / s.
  • Coolant is supplied via the nozzle 7, which flows upward in the double jacket 4 of the venturi quench and thereby cools the metal wall.
  • the coolant enters the hot gas stream via supply openings 5, which can also be designed as nozzles, and is torn into small droplets, one of which form a large specific surface area and lead to extremely rapid cooling of the hot gasification gas.
  • Torn slag particles that are liquid at the high gas temperatures are also cooled, solidified and carried away with the gas stream. Solid particles such as soot or other unmelted constituents are wetted and separated from the cooled gas stream in the following separator 6 together with water droplets.
  • the separator 6 can be designed according to the prior art, for example as a centrifugal or lamella separator. Water is usually used as the cooling medium, which is circulated after an intermediate cleaning by dust separation.
  • hydrohalic acid can already be supplied as a coolant and detergent via the connector 7 and the feed openings 5 in order to obtain a sufficiently high acid concentration during the washing process which is running simultaneously in the Venturi quencher and subsequent stages .
  • Figure 2 shows a certain constructive embodiment of the inventive solution, in which the coolant supplied via the connector 7 for cooling the metal wall of the Venturi tube first directed downwards, deflected and the double jacket-like space 4 in the narrowest cross section of the Venturi tube 3 via the feed opening 5 hot gas stream coming from the gasification chamber 2 is given up.
  • FIGS. 3 and 4 show special solutions for the coolant supply 5. While in FIG. 3 the coolant is guided over a weir-like arrangement, it flows into the confuser of the venturi quencher 3 as a coolant film in FIG.
  • the solutions according to FIGS. 3 and 4 have in common that the coolant is fed in the confuser before the narrowest cross section of the venturi quencher 3. It is accelerated by the gas flow and torn into the smallest droplets in the narrowest cross section.
  • the film-like design of the coolant flow simultaneously causes additional cooling of the metal wall in the confusion area of the venturi quencher 3.
  • FIG. 5 shows the arrangement of an additional washing and cooling stage 8 downstream of the Venturi quencher 3. This arrangement is particularly advantageous if certain components such as hydrogen halides can be obtained from the raw gas stream for the extraction of hydrohalic acids.
  • the separator 6 is then connected to this additional washing and cooling stage 8.
  • FIG. 6 shows the arrangement of a controllable venturi quencher 3.
  • Rigid venturi quenchers 3 have the disadvantage that the velocities in the venturi quencher 3 also vary with the amount of raw gas fluctuating. If the gas velocity becomes too low, the coolant is broken up only insufficiently. Only larger coolant drops are formed, the surface of which is too small for the desired cooling and washing effect.
  • the remaining cross section can be regulated depending on the amount of raw gas, so that the desired speed can be set independently of the amount of raw gas.
  • the drive rod In order to prevent raw gas or coolant from escaping, the drive rod is guided through a sealing system 10. In order to keep the mechanical effort low, the quenched raw gas is discharged laterally.
