Definitions

  • the invention relates to a drying plant for water-rich lignite, in which the coal to be dried is preheated, steamed under superatmospheric pressure and subsequently dried.
  • the first conveyor which is directly connected to a storage bunker for the coal to be dried, which is preferably designed as a vibrating trough, allows the coal to be showered directly in a simple manner for the purpose of preheating with hot waste water from the subsequent drying process. In this way, residual heat from the process is used and the wastewater load is reduced, since wastewater from the process is circulated.
  • the subsequent wet sieve advantageously serves for the separation of the residual fine grain fraction and the separation of adhering dust, with an additional preheating of the coal with residual steam from the waste water.
  • the subsequent conveyor which is preferably designed as a steep conveyor belt, allows the preheated raw lignite to be fed in a space-saving manner without any significant temperature loss to a preheating device which, according to the invention, is provided with a pressure lock at the feed point and connections for steam lines.
  • a preheating device which, according to the invention, is provided with a pressure lock at the feed point and connections for steam lines.
  • this preheating device further heating of the material to be dewatered with steam is made possible, and in that a direct connection between the preheating device and the autoclave is established via a further pressure lock for the discharge from the preheating device and the task into an autoclave which can be charged with saturated steam, here, too, the transfer into the autoclave is made possible in an energy-saving manner.
  • the pressure lock between the preheating device and the autoclave also enables the lock evaporation to be used directly to preheat the material to be dried.
  • sewage lines are connected to the autoclaves to which saturated steam can be applied, via pressure valves, via which the expelled process water can be drained off and thus need not be subjected to further heating.
  • a sieve drum inside the autoclave provided with a rotary drive.
  • the preheater and the autoclave can operate under superatmospheric pressure are held so that a material to be dried that is optimally prepared for saturated steam drying is transferred directly to the drying stage within the autoclave.
  • Another pressure lock for the discharge and expansion of the steamed material is connected to the autoclave and an after-dryer is provided in which part of the remaining amount of water evaporates due to the latent heat at atmospheric pressure, the drying being promoted by the introduction of hot air .
  • the after-dryer is preferably designed as an oscillating dryer and has a connection for preheated air, whereupon a conventional device for removing the dry coal is connected.
  • the product can also be cooled and / or rendered inert in the after-dryer.
  • the waste water lines from the autoclave are preferably connected to trailer vessels to which lines for C0 2 , waste water and sludge and a line to a relaxation vessel are connected.
  • the trailer vessels also serve for the pre-separation of solids in the wastewater and the wastewater collected in the trailer vessels can be fed directly to a heat exchanger for preheating air and with the separation of residual steam for showering material to be dried.
  • the expansion steam formed in the expansion vessel can be used directly for preheating in the preheating device provided with a pressure lock, with this preheating device, which advantageously contains a sieve drum with a rotary drive, the separated Hot water can be fed to the residual steam separating vessel via pressure valves.
  • the residual steam from the waste water obtained from the residual steam separating vessel can be fed into the wet sieve and can in turn be used there for preheating purposes.
  • a dedusting device can be connected to the after-dryer in order to be able to remove dry coal that is as dust-free as possible.
  • wastewater is only discharged from the process at a single point, this point being provided below the wet sieve. Only the wastewater that flows off here requires wastewater treatment, whereas all other facilities are partly completely closed and partly only connected to the environment via a dedusting system.
  • the raw lignite withdrawn from a storage bunker 1 is applied to a first conveyor 2 designed as a vibrating trough and over-brewed with hot water supplied via a line 3.
  • the coal can be preheated to temperatures of around 40 ° C - 60 ° C.
  • the preheated coal is then fed onto a wet sieve 4, residual steam and optionally wastewater from the wastewater or vapors being applied via a line 5. There is thus a further preheating of the feed material.
  • the screen overflow with a grain size of 3 - 40 mm is fed into a steep conveyor belt 6 and passes into a pressure lock 7 designed as a rotary pressure lock Preheating device 8.
  • a screening drum 9 is arranged within the preheating device 8, the drive of which is designated by 10.
  • a line 11 for steam and a line 12 for waste water are connected to the preheating device 8.
  • the preheating device 8 is connected to the autoclave 14 via a pressure lock 13, which is again designed as a rotary pressure lock.
  • a sieve drum 15 with an associated rotary drive 16 is in turn arranged within the autoclave 14.
  • a saturated steam line 17 and a waste water line 18 are connected to the autoclave 14.
  • the coal is preheated in the preheating device to temperatures of up to 200 ° C. at 15 bar and is preferably kept in a temperature range between 120 ° C. and 150 ° C.
  • the actual drying process is carried out by applying saturated steam and possibly superheated steam or superheated steam at pressures of up to 45 bar, depending on the coal and the desired degree of drying.
  • the discharge takes place in turn via a pressure lock, which is designed as a cellular wheel pressure lock and is designated by 19.
  • a post-dryer 20 is connected to this cellular wheel pressure lock 19, in which the coal is charged with preheated air and post-evaporation takes place.
  • the after-drying device 20 is designed as an oscillating dryer and is connected via a line 21 to a dedusting device.
  • the hot air is supplied via a line 22.
  • the dried coal is discharged by a conveyor 23.
  • Drying in the autoclave can be carried out in a particularly advantageous manner with superheated steam, the superheating of the steam being chosen with the proviso that saturation is achieved by the subsequent evaporation of the coal water that has escaped.
  • feed water and energy for steam generation can be saved and less occurs Amount of condensate, which reduces the amount of waste water to be treated.
  • the use of superheated steam is simplified by the preheating with steam under pressure and only the water content of the coal after preheating is taken into account.
  • the waste water line 18 is connected to the trailer vessels 24.
  • the expelled coal water and the condensate of the saturated steam supplied are collected in these trailer vessels.
  • C0 2 is withdrawn via a line 25.
  • the solids are discharged via sludge lines 26.
  • the hot waste water is transferred via lines 27 into an expansion vessel 28. In this expansion vessel 28 there is a pressure reduction and associated steam recovery.
  • the hot waste water is fed to a preheating device 29 for the hot air of the dryer 20 and subsequently reaches a residual steam separating vessel 31 via a line 30.
  • the residual steam separated in this residual steam separating vessel 31 is fed to the wet sieve 4 via line 5, whereas the remaining hot waste water portion is fed back to conveyor 2 via line 3.
  • the excess wastewater is fed to a wastewater treatment system via a line 32.
  • the expansion steam from the expansion vessel 28 is fed to the preheating device 8 via a line 33.
  • the condensate derived from this preheating device 8, which is drawn off via the line 12, can be added to the waste water fed to the residual steam separating vessel 31 via the line 30.
  • the saturated steam introduced into the autoclave 14 is advantageously blown from above onto the outside of the silicon drum jacket by means of flat jet nozzles, which at the same time ensures that the drum jacket is not blocked.
  • sieve drums are in primarily used slotted screen drums.
  • the residence time of the coal in the autoclave 14 is selected depending on the grain size and can be chosen to be smaller for small grain than for larger grain. A typical residence time of 5 minutes for grain sizes of 5 - 20 mm, a residence time of 10 min for grain sizes of 10 - 30 mm and a residence time of 20 min for grain sizes of 20 - 40 mm.
