Definitions

  • the invention concerns a steam dryer for evaporating of water and/or other liquid from wet materials or evaporating of materials in a liquid state, comprising:
  • a rotary drum is disclosed in EP publication No. 0 305 706 A2 .
  • the rotary drum described in this publication comprises a cylindrical shell provided with end plates at the feed end and the discharge end of the drum.
  • Axial steam pipes and a steam distribution manifold are located in the drum and said steam distribution manifold supplies the axial steam pipes with steam through radial steam pipes or channels.
  • the steam distribution manifold, axial steam pipes and radial steam pipes are all located in the drum so that they are exposed to wear. Because the drum comprises a uniform space between the end plates of the drum without any intermediate plate between said end plates the level of the material to be dried in the drum is low and therefore also the drying capacity of the drum is low.
  • US Patent No. 2,100,444 discloses a rotary drier comprising a cylindrical shell provided with a feed end and a discharge end for the material to be dried. Exhaust gases formed during drying are discharged from the drum at the feed end of the drum whereby the gas flow inside the drum is opposite to the material flow and so this rotary drier is a counter current flow drier.
  • the rotary drier of US 2,100,444 is not provided with any intermediate plate and therefore the level of the material to be dried in the rotary drier is low leading to a low drying capacity of the drier.
  • the object of the present invention is to provide a steam dryer for evaporating of water and/or other liquid from wet materials or evaporating of materials in a liquid state, in which dryer the steam distributor manifold, radial connection pipes and flexible hoses are not exposed to the difficult environment of flying dusty, moist and corrosive vapour so that abrasive wear is minimized or at least it does not cause problems and that the need for maintenance has remarkably been reduced and if needed the maintenance easy to do due to the easy access to said components.
  • another object of the present invention is to provide a steam dryer in which the contact area between the steam pipe elements and wet material is increased in order to obtain higher drying efficiency of the dryer.
  • a steam dryer in accordance with claim 1 is provided.
  • the stationary end chamber is arranged at the discharge end area of the drum in the axial direction between the discharge end plate and the feed end plate such that the discharge end plate is situated outside of the discharge end chamber, said discharge end chamber surrounding a portion of the drum and having a lower opening to discharge dried material or remaining liquid therethrough from the drum and from the discharge end chamber and an upper opening to discharge vapour therethrough from the drum and from the discharge end chamber
  • the steam distributor manifold is arranged at the discharge end of the drum outside of the discharge end plate to supply the steam pipe elements with steam intended for evaporating of water and/or other liquid from wet materials or evaporating of materials in a liquid state as said materials pass through the drum and for removing condensate formed in the steam pipe elements
  • a dam plate is structured and arranged in the drum at the discharge end area of the drum at a distance from the discharge end plate, the dam plate having an opening formed therein through which opening dried material
  • the drum of the steam dryer is divided into a plurality of separate compartments around the axis of rotation of the drum in order to increase the contact area between the steam pipe elements and the wet material in the drum.
  • the wet material from which water or other liquids are to be evaporated is fed into each of said compartments in which it is turned and from which it is conveyed to the discharge end of the drum when the drum is rotating.
  • the volumetric efficiency of the drum is thereby better than in the prior art dryers.
  • the drum of the dryer and the set of pipes placed inside the drum are rotated during drying, and therefore the drum is provided with a mechanism of rotation suitable for this purpose.
  • a mechanism of rotation suitable for this purpose As an example of this a mechanisms described in publication WO 98/02700 or in patent US 6,415,527 can be mentioned. Also, other types of mechanisms of rotation can be used.
  • the steam pipe elements placed in the drum can be removed from the drum and replaced separately.
  • the service life and the usability of the dryer are improved, because the tube elements can be replaced quickly and easily, which reduces the standstill time of the dryer.
  • high drying efficiency is obtained, because the filling degree of the drum can be made high.
  • the drum of the steam dryer in accordance with the invention can also be in an inclined position so as to enhance the transfer of the material to be dried and to remove the condensate.
  • the steam dryer 10 comprises a cylindrical rotatable drum 11 having a shell 12 with an inner face 12a and an outer face 12b. Steam pipe elements 26 have been fitted in the interior of the drum 11 to rotate along with the drum 11.
  • the drum 11 is provided with a feed end 14 structured and arranged to receive wet material or material in a liquid state into said drum 11 said feed end 14 being closed by a feed end plate 15.
  • the drum 11 is further provided with a discharge end 16 structured and arranged to discharge vapour and dried material or concentrated liquid from said drum 11 said discharge end 16 being closed by a discharge end plate 17.
  • a stationary end chamber 18 is structured and arranged at the discharge end 16 area of said drum 11 in the axial direction between said discharge end plate 17 and said feed end plate 15 so that the discharge end plate 17 is outside of said discharge end chamber 18.
  • said stationary discharge end chamber 18 surrounds a portion of the drum 11 and it is provided with a lower opening 19 for discharging dried material or remaining liquid through said lower opening 19 from said drum 11 and said discharge end chamber 18.
  • the end chamber 18 is further provided with an upper opening 20 to discharge vapour therethrough from said drum 11 and said discharge end chamber 18.
  • the wet materials from which water and/or other liquids are to be evaporated or the materials in a liquid state to be evaporated are passed into the interior of the drum 11 through the feed end 14 of the drum 11.
  • the material passes in the axial direction through the drum 11 and is discharged through the stationary discharge end chamber 18 arranged at the discharge end 16 of the drum 11.
  • the wet material from which water and/or other liquids are to be evaporated or the material in a liquid state to be evaporated is introduced into the drum 11 by conveyance means 22, e.g. a belt conveyor.
  • conveyance means 22 e.g. a belt conveyor.
  • a conveyor of a different type can also be used and it is recommended to choose the conveyor type according to the materials to be introduced into the drum 11.
  • an opening 23 has been formed into the feed end plate 15 at the feed end 14 of the drum 11, through which opening 23 the conveyance means 22 supply the material into the interior of the drum 11.
  • the steam enters into the steam distributor manifold 21 through a rotary joint (not shown) and further therethrough to the steam pipe elements 26 placed in the interior of the drum 11.
  • the steam distributor manifold 21 has been fitted in the axial direction outside of the discharge end plate 17 and so axially outside of the discharge end 16 of the drum 11.
  • the steam distributor manifold 21 is arranged to rotate with the drum 11.
  • the steam distributor manifold 21 is provided with a plurality of radial connector pipes 24, whose inner ends open into the interior of the steam distributor manifold 21 and whose outer ends are closed.
  • the radial connector pipes 24 communicate with the steam pipe elements 26 in the interior of the drum 11 through flexible hoses 25 or othet suitable means.
  • the steam pipe elements 26 are structured and arranged to be inserted within the drum 11 and being rotatable with said drum 11.
  • Each steam pipe element 26 comprises two axial pipes 27 parallel to a longitudinal direction of the drum 11 and a plurality of longitudinally spaced transverse intermediate pipes 28 which interconnect said axial pipes 27.
  • the steam pipe elements 26 or actually the axial pipes 27 of said steam pipe elements 26 can extend across the entire axial length of the drum.
  • the steam pipe elements 26 may alternatively have been formed so that only a part of them extends across the entire axial length of the drum 11 while the rest of the steam pipe elements 26 extend only partially across the axial length of said drum 11 from the steam supply end, i.e. from the discharge end 16 of the drum.
  • As a third alternative of the steam pipe elements 26 all of them may have been formed to extend only partially across the axial length of the drum 11.
  • the steam pipe elements 26 are fitted one inside the other in a radial direction of the drum at a distance from one another so that the transverse intermediate pipes 28 of an adjacent set of steam pipe elements 26 which are also placed substantially at the same distance from the longitudinal centre line L of the drum 11, form a ring-like formation parallel to the circumference of the drum 11. This naturally depends partly on the form of the intermediate pipes 28.
  • said steam pipe elements 26 are arranged within the interior of the drum 11 such that the axial pipes 27 of each steam pipe element 26 are placed at a different distance from the longitudinal centre line L of the drum 11.
  • a plurality of support constructions 29 have been arranged, to which support constructions 29 the steam pipe element 26 have been attached by fastening means, which permit movement arising from thermal expansion of the steam pipe elements 26.
  • the mechanism of rotation of the drum 11 and the mechanism of inclination of the drum 11 are not shown in the figures in the drawing, but, as was already stated above, as the mechanism of rotation and as the mechanism of inclination, it is possible to use, for example, the same type of arrangement described in International publication WO 98/02700 or in US Patent No. 6,415,527 . In such a case, by means of the angle of inclination of the drum 11 and the adjustable speed of rotation, the time the wet materials from which water or other liquids are to be evaporated or materials in a liquid state to be evaporated, stay in the steam dryer 10 can be regulated.
