Definitions

  • the invention relates to a gas generating plant with a fluidized bed or entrained-flow pressure reactor in which coal is gasified, and with a device for cleaning the high-pressure raw gas.
  • Fine coal is gasified under high pressure within the pressure reactor.
  • the gas generated in this way can be used, for example, to generate energy.
  • the capacity of the device assigned to the gas generating plant and used for cleaning the raw gas must also be adaptable.
  • So-called wet scrubbing is generally used to clean a raw gas.
  • This type of cleaning has the disadvantage, however, that the raw gas emerging from the gas generation plant is cooled relatively strongly. This cooling represents a loss of energy which adversely affects the overall efficiency of a plant containing the gas generating plant.
  • the device used for cleaning the raw gas has at least two cyclones connected in parallel on the input side and in that the cyclones can be switched on or off individually.
  • a cyclone is known per se in a different context than a device for cleaning a gas. As part of a Gaserzeu g but ungsstrom using a single cyclone would not be considered because of the lack of the necessary adaptability. However, if several cyclones are connected in parallel and these can be switched on and off by means of a corresponding control depending on the respective power requirement, the desired adaptability is ensured, while at the same time the use of a wet wash leading to energy loss can be avoided.
  • the supply of the raw gas to the cyclones takes place by means of a pipeline into which, seen in the course of the line axis, one of the gas outlet connections leading to a cyclone opens laterally, and that in the Pipeline is arranged in the direction of the line axis movable, the line cross section locking piston.
  • the end face of the closing piston facing the gas flow runs in an arc shape in the direction of the cross section of a gas outlet connection piece. In this way, an almost continuous deflection of the gas flow between the longitudinal axis of the pipeline and the axis of the gas outlet connection is possible.
  • the gas generated in a compressed gas generator 10 enters a pipeline 11.
  • the direction of flow is indicated by an arrow 12.
  • In the pipeline 11 open approximately radially extending gas outlet stubs 13, each of which leads to the entrance of a cyclone 14, 15 and 16, respectively.
  • Each of the three cyclones 14, 15 and 16 has a clean gas outlet 17 in its upper region, while a dust outlet 18 is located on the underside of the respective cyclone 14, 15 and 16.
  • a closing piston 19 Arranged in the pipeline 11 is a closing piston 19 which is movable in the longitudinal direction thereof and which has the shape of a rod which extends through the pipeline 11.
  • the inflow side of the closing piston 19 runs in an arc shape such that the radius of the curved inflow surface merges into a corresponding course of the respective gas outlet connection 13 as continuously as possible. This ensures a largely uniform deflection of the gas flow in the respective gas outlet connection 13.
  • the locking piston 19 is connected to a drive, not shown here, by means of which an adjustment of the locking piston 19 in the directions indicated by the double arrow 20 is possible.
  • the drive can be designed as a piston-cylinder arrangement or as a motor with a subsequent rack and pinion gear or the like.
  • the cyclones 14, 15 and 16 are connected in parallel to one another.
  • the closing piston 19 By adjusting the closing piston 19 into the corresponding position, it is possible to use only the cyclone designated by the reference number 14 To apply gas.
  • the closing piston 19 is in a corresponding position on the gas outlet connection 13 assigned to the cyclone 14, or the closing piston 19 can be brought into the corresponding position on the gas outlet connection 13 of the cyclone 15 or the cyclone 16 in order to adapt to the amount of gas to be cleaned in each case , so that two or three cyclones are then in operation.
  • This allows a good adaptation of the amount of gas coming from the compressed gas generator 10 to the amount of gas at which a cyclone of the type used has its optimum degree of purification.
  • the individual cyclones can be switched on and off by means of the proposed device with only little technical effort and at very short notice.
