Definitions

  • ABSTRACT A method and apparatus for cooling hot particulate material such as cement clinker discharged from a furnace, such as a rotary kiln.
  • a first heat exchanger of the type wherein cooling gas is passed upwardly through the material to cool the material and this gas is heated by the hot material and supplied to the kiln as preheated combustion air.
  • the first heat exchanger is followed by a clinker breaker and a second heat exchanger which includes an arrangement for spraying the hot material with water.
  • the spray cooler is followed by a third heat exchanger of the type wherein cooling air is passed upwardly through the material in direct contact with the material.
  • the cooling air which flows through the third heat exchanger flows directly through the first heat exchanger.
  • a material seal is provided between the second and third heat exchangers to prevent cooling air from passing through the second heat exchanger.
  • a vent from the second heat exchanger is provided to exhaust steam produced when the water contacts the hot material.
  • a control may be provided so that the amount of water sprayed onto the hot material at the second heat exchanger is responsive to the temperature of the material discharged from the third heat exchanger.
  • ambient air may be supplied'directly to the hottest material discharged from the kiln for passage through the first heat exchanger.
  • This invention relates to material coolers and in particular to recuperative type heat exchangers wherein cooling air is passed through the hot material to cool the material and the cooling air which is heated by the hot material is supplied to a furnace for use as preheated combustion air. More particularly, the invention provides a heat recuperative type material cooler which substantially eliminates the need for dust collection equipment.
  • Heat recuperative type material coolers such as that used for cooling cementclinker discharged from a rotary kiln are generally known and can be illustrated by apparatus such as that shown in U.S. Pat. Nos. 2,137,158 and 2,846,778.
  • material is discharged from the furnace onto a conveyor, such as a reciprocating grate conveyor, which advances the material through the cooler. Cooling air is blown upwardly through the bed of material and cools the ma terial. As the material is cooled, the air is heated by the hot material and returned to the furnace or rotary kiln as combustion air.
  • the apparatus has as its primary advantage the ability to reduce fuel consumption by the furnace by using preheated combustion air.
  • a disadvantage of the reciprocating grate type material cooler is that in order to reduce the temperature of the material to a level which can be conveniently handled, it is necessary to pass more cooling air through the hot material than can be used by the furnace.
  • the cement clinker will be cooled from a temperature of about 2,500 to 150 F.
  • In order to'achieve all of this cooling by direct heat exchange with air about three times as much air is needed for cooling as can be used in the burning of cement clinker.
  • the two-thirds which cannot be used by the kiln must be vented to atmosphere.
  • As the cooling air passes through the bed of cement clinker it will pick up dust and fine particles of cement clinker. These fine particles of cement clinker are a valuable product which should be collected by passing the excess air through a high efficiency dust collector.
  • Such dust collectors add to the expense of the material cooling system and a reduction in their size of their elimination would be advantageous.
  • a cooler has been provided which is capable of cooling hot material such as cement clinker discharged from a rotary kiln by the use of gas such as air passing through the hot material to maintain the advantages of the recuperation type heat exchanger. Substantially all of the air is returned to the furnace as preheated combustion air. However, it is be lieved that the need for a high efficiency dust collection system has been substantially eliminated. This is achieved'by providing a heat exchanger which sprays water onto the hot material and substantially preventing cooling air passing through the gas heat exchanger from entering the liquid heat exchanger.
  • apparatus for cooling hot particulate material discharged from a furnace and for supplying preheated combustion air to said furnace comprising a first heat exchanger including means for supporting the material to be cooled and advancing material through the heat exchanger; conduit means for conducting material to be cooled from said furnace to said first heat exchanger; a second heat exchanger flow connected with said first heat exchanger for receiving material from said first heat exchanger and including means for supplying a cooling liquid for direct contact with the material to be cooled; a third heat exchanger flow connected with said second heat exchanger for receiving material from said first heat exchanger and including means for supporting the material to be cooled and advancing the material through the heat exchanger; means for supplying cooling air to said third heat exchanger for sequential passage through the material in said third and first heat exchangers whereby cooling air passes through the coolest material first and the hottest material last and is heated by said material; means for conducting said heated air to said furnace; and breaker means positioned between two of said heat exchangers.
  • the objects will also be carried out by the method of cooling hot particulate material comprising the steps of passing a cooling gas through the material to be cooled; furtherv cooling said material by directly contacting said material with a liquid while substantially preventing the passage of a cooling gas therethrough; and passing a cooling gas through said material.

  • means are provided for reciprocating the frame 14 to which are secured the movable grates l6 and the reciprocation of the frame 14 and grates 16 causes an advancement of material through the heat exchanger 6.
  • Gaseous fluid such as air is supplied, in a manner hereinafter described, to a plenum below the conveyor for passage through the conveyor and the bed of material 13 to thereby cool the material.
  • a material breaker 20 is provided at the discharge of the heat exchanger 6 for reducing the size of large aggregateles of material.
  • a grizzly 22 allows the passage of small particles of material into the second heat exchanger 8 and the breaker 20 reduces the size of the large particles to permit their passage through the grizzly 22.
  • a partition 24 aids in the breaking of large particles of material by the action of the breaker 20 throwing these large particles against the partition wall 24.
  • the partition 24 extends down towards the bed of material 13 a distance sufficient so that the depth of the bed of material 13 provides a material seal at the outlet 25 of the heat exchanger 6 between the heat exchanger 8 and the heat exchanger 6.
  • the second heat exchanger 8 includes means for supplying liquid for direct contact with the material to be cooled.
  • this means includes a pair of shower heads supplied with water through a conduit 32 from a suitable source (not shown).

  • the heat exchanger 8 may include a permeable bottom 38 which permits excess water to be drained from the material to a discharge 39.
  • the partition 38 may include a reciprocating grate conveyor or some other pusher means for advancing material from the heat exchanger 8 through the material outlet 37 towards the third heat exchanger 10.
  • the bed of material is maintained at a depth sufficient to cover the outlet 37 formed by the partition 36 and form a material seal between the third heat exchanger 10 and the second heat exchanger 8.
  • the heat exchanger 10 is substantially the same as the heat exchanger 6, but the reciprocating grate conveyor which supports a bed of material 51 in the heat exchanger 10 is horizontal rather than inclined. If
  • the conveyor 50 may be inclined rather than horizontal.
  • the conveyor 50 includes a frame 52 and a plurality of alternate rows of fixed grates S4 and movable grates 55 each having passages therethrough. Means (not shown) are provided for reciprocating the frame 52 and the movable grates 55 in a well-known manner to advance material from the outlet 37 of the heat exchanger 8 to the discharge 60 of the cooling apparatus 5.
  • a plenum chamber 62 is provided under the conveyor 50 and may be divided into chambers 63 and 64, each having a fan 67 and 68 respectively, connected thereto for supplying cooling gas to the plenum chamber 62 for passage upwardly through the conveyor 50 and the bed of material 51 supported on the conveyor.
  • the cooling gas passes through the material 51 to cool the material and such cooling gas is heated by the material.
  • the area above the heat exchanger 10 and below the conveyor 12 of the heat exchanger 6 forms a plenum chamber 70 for the heat exchanger 6.
  • the chamber 70 may be divided by suitable partitions such as 72 to provide chambers 73 and 74.
  • the cooling gas passes into the plenum 70 of heat exchanger 6, then sequentially through conveyor 12 and the bed of material 13.
  • the bed of material 13 is cooled and the cooling gas is further heated by the hot bed of material 13 and returned as preheated combustion air to the kiln 1 through the conduit 2.
  • the material seal formed at the outlet 37 of the second heat exchanger substantially prevents the cooling air from short circuiting through the liquid heat exchanger 8.
  • the partition 72 is approximately aligned with the partition 65. Since the coolest material will be near the end of the third heat exchanger 10, the gas in chamber 73 will be cool and achieve the best heat exchange with the hottest material in the apparatus 5 which is at the beginning of the first heat exchanger 6.
  • an important feature of the present invention is that the amount of water sprayed onto the material in the heat exchanger 8 be sufficient to cool the material a substantial amount, but not so great as to result in a wet product being discharged from outlet 60 of the apparatus 5.
  • the material discharged from the heat exchanger 8 should retain sufficient heat to dry the material when combined with the passage of cooling gas through the material.
  • a temperature sensor 3 0 is provided in the discharge 60 and this temperature is used to control valve 34 and the amount of water sprayed onto the hot material.
  • the cooler of the present invention provides the advantage that all gas blown through the material to cool the material is returned to the kiln l as preheated combustion air thereby maintaining the advantage of prior recuperative type heat exchangers.
  • the cooler of the present invention also provides that substantially no cooling gas is exhausted to atmosphere thereby eliminating the need for a high efficiency dust collector.
  • FIG. 2 is substantially the same as that shown in FIG. 1 but has the addition of a valve means between the heat exchanger 8 and the heat exchanger 10.
  • the valve means 90 replaces the material seal formedat the outlet 37 by the partition 36 and serves to insure that cooling gas will not be short-circuited through the heat exchanger 8 to the outlet 40.
  • a valve 61 may be added to the cool material outlet 60. This will insure that a material seal is formed at this outlet to prevent cooling air which passes through the third heat exchanger 10 from being short-circuited through the outlet 60 and not passing through heat exchanger 6.
  • a fan has been provided for supplying ambient cooling gas to the initial portion of the first heat exchanger 6.
  • a partition 96 is provided in the chamber 73 to provide a chamber 97 to direct this ambient cooling air to the first rows of grates l5 and 16 to insure that the hottest material is quenched with cool air.

  • the apparatus may be modified by putting a floor between the gas heat exchangers 6 and 10 and passing the gas from the heat exchanger 10 through fans before it is supplied to a plenum below the conveyor 12. If desired, a walkway may be provided below the conveyors 12 and 50 to permit servicing. For certain applications, it may be desirable to add cooling air to heat exchanger 8, but this should not be air in an amount sufficient to entrain large quantities of dust.
  • the passing of air through the material in heat exchanger 8 could be used where a small amount of cooling air is added below the heat exchanger 8 to insure that any means provided for moving the material through the outlet 37 is not damaged by constant exposure to hot material.
  • the apparatus could also be modified by extending the heat exchanger 10 out from heat exchanger 8 in line with heat exchanger 6 rather than under heat exchanger 6 in the double deck manner shown in the drawing. This arrangement may be employed where head room would not permit the double deck arrangement.
  • the material is cooled by first passing a cooling gas through the hot material, then further cooling is achieved by directly contacting the material with a liquid while substantially preventing the passage of cooling air through the material, and subsequently cooling the material by passing a cooling gas through the material. Substantially all of the spent cooling gas is returned to the furnace as preheated gas. The vapor formed by the direct contact of the material with a liquid is exhausted through an outlet independent of the conduit which returns preheated gas to the furnace.
