Definitions

  • the present invention relates broadly to paper machines, and is more particularly concerned with novel method and lapparatus for controlling the moisture content across the width of Ia fibrous web being treated or produced.
  • Another object of the invention is to provide a method of drying ta web of paper and the like, which comprises advancing a moist web toward a drying cylinder, eX- amining said web for the presence of moisture streaks therein extending generally in the direction of travel thereof, and while said web is against said cylinder, directing Iagainst the transverse port-ions of the web containing said streaks a relatively greater volume of heated air than against other portions thereof to produce transversely across the web a relatively uniform moisture content therein.
  • a further object of this invention is to provide means for selectively directing high velocity and high temperature air against predetermined portions of the transverse wid-th of a web of paper and the like received by a drying cylinder, said means comprising a hood supported adjacent said cylinder, means dividing the hood into a plurality of drying chambers, and means controlling the air discharged frcm cach of said chambers into drying relation with the web to leffect in accordance With the lweb moisture content a relatively higher degree of drying in predetermined portions of the .transverse width of the web than in other portions thereof, so that the moisture content of the web is generally uniform thereacross.
  • FIGURE l is a somewhat diagrammatic view of a drier section of ⁇ a paper machine and embodying therein drying means constructed in accordance with the principles of this invention
  • FIGURE 3 is a vertical sectional view of the drying means or hood of this invention positioned adjacent a conventional drying cylinder;
  • FIGURE 6 is a sectional view of the plate means of FIGURE 5, and showing in detail the configuration of a pair of orifices therein.
  • FIGURE l a dry end section 10 of drying apparatus of a paper machine with which the instant invention is of important application.
  • the dry end section l@ comprises a first row of horizontally aligned drying cylinders or drums lined of which four are shown in the exemplary embodi-ment illustrated, and a second row of horizontally aligned drying cylinders 12o-d staggered with respect to the drying drums 11 of the first row.
  • a web of paper W passes alternately about the drying cylinders 1l and l2, and is maintained in contact with the surfaces of the drying cylinders lla and 11b by a felt 13 and against lthe surfaces of the drying drums 12m-d by a felt i4.
  • a suitable number of rollers 15 are arranged to guide the felt i3, and rollers le guide the -felt lli.
  • the drying arrangement described will be recognized as of essentially conventional construction, and in performance of the drying cycle, the cylinder or drum lld may be a sweat drier supplied with relatively cold water to cause condensation on the surfaces thereof from surrounding moist atmosphere, the condensate being picked up by the web W traveling over this drier to restore a portion of the moisture removed by any overdrying.
  • effective uniform moisture control throughout the transverse width of the web W may render unnecessary the use of the sweat drier ldd.
  • Web moisture probook control means provided by applicants is indicated generally in FIGURE l by the numeral 17, and it may be seen therefrom that such means are located in close Wrapping relation to the drying cylinder 11C, although identical means could additionally be employed in association with the drier drum or cylinder 120.', it being understood that felt i4 would be removed from such drum.
  • the control means 17 is preferably in the form of an arcuate housing 18 supported by a suitable means in close relation to a portion of the circumference of the cylinder llc and extending a suicient dis-tance thereabout to be coextensive with the wrap of the web W during travel along this portion of the circumference ofthe rotatable drum lic.
  • Each plenum is arcuately curved along its surface adjacent the cylinder 11C and supported therein and extending transversely across the width of each plenum is a perforated plate member 2.9, the structural details of which will be specifically described hereinafter.
  • the plenums 23, 26 and 27 are in other respects of generally triangular configuration when viewed in end, although, of course, the shape thereof may be widely varied.
  • Each inlet conduit 22 formed on the hood or housing 18 supports therewithin a damper 3u to selectively open or close any one of said conduits to control the heated air ilow to a particular arcuate row of plenum chambers 23a, 26a and 27a, whereby high velocity and high temperature air is impinged against the paper web W only along that transverse portion thereof wherein moisture streaks are present.
  • the dampers 30 may be pivoted to a particulaiposition within each conduit 22 by suitable motor means (not shown) remotely controlled by the paper machine operator so that any particular set of plenum charnbers may discharge air against the web in accordance with the operators ldetection of wet streaks or other moisture irregularities in the sheet when the so-urce of said irregularities are upstream of the drying cylinder 111C.
  • Each inlet conduit 22 to the central plenum 23 connects with a main header pipe 31 (FIGURE 2) closed at one end and connecting at its opposite end With a conduit 32 leading to a heater 33, which in turn connects with a conduit or a pipe 34.
  • the latter pipe has a branch portion 34a therein, and a damper 35 controls the extent of opening of said portion, and in cooperation with an exhaust fan 36, regulates the moisture balance in the system.
  • the conduit 34 further connects with a blower 37 receiving a conduit 38 connecting with branch conduits 39 (two of which are shown) leading to the interior of the hood or housing 18, the branch conduits 39 connecting with the conduit 38 by a common connecting conduit 4t?.
  • the exhaust fan 36 is effective to maintain a slightly sub-atmospheric pressure in the return portion of the system, and accordingly, replacement or make-up air is permitted to enter the outer plenum chamber 41 only in suicient and relatively small quantities to prevent the loss of heated air to the surrounding atmosphere.
  • the quantity of ⁇ air so entering will replace the saturated air exhausted via the fan 36.
  • this fan is arranged to remove a controlled fraction of the spent air from the outer plenum 41 in such quantities that -a desired moisture balance is maintained in the system, and by positioning of the damper 35, and/ or the exhaust fan 36, the relative humidity may be controlled by exhausting a controllable quantity of saturated air to a particular or pre-selected constant value.
  • the blower 37 pressurizes the air received from the outer plenum 41 through the conduits SiS- 40, and directs this air through the conduit 34 into the heater 33, whereat the temperature is raised to the desired level for eifective drying action. In this manner, there is a controlled re-circ-ulation of the heated air, the temperature of which is controlled by the heater 33 and the velocity controlled in turn by the blower 37 by its pressurizing function.
  • a further structural feature of the instant invention is the particular configuration of the perforated plate 29 supported by each of the plenums 23, 26 and 27.
  • the plate 29 is provided with a plurality of nozzle openings 42 arranged when the plate is viewed in plan in groups of three which form an equilateral triangle which is slightly askew from the sheet travel direction indicated by the arrow applied to FIGURE 5.
  • Each nozzle opening 42 is defined by an inwardly flared throat portion y43, and it has been found that this flared configuration reduces orifice losses and permits high velocity jets of air to operate to scrub away the surface film of Asaturated moisture vapor traveling with the paper web W.
  • the flared nozzles promote a cyclonic turbulence between the air iets issuing from the openings 42, this turbulence being indicated generally in the directions of the arrows applied to HGURE 6.
  • the thickness of the perforated plate 29 is presently preferred to be 1/41 inch, 'and the holes or openings 42 therein may be either extruded or drilled, the latter technique providing a plate having the advantage of better strength and rigidity.
  • the preferred spacing of the body portion of the plate 29 from the surface of the web W traveling about the dryingy cylinder 11C is one inch when the hole diameter and ratio of hole area to total area are within the suggested limits. This spacing appears at present to provide optimum heat transfer and drying rate in accordance with the equation h :CPn
  • n-:an exponent approximately equal to 0.23.
  • the desired transverse width of the plenum chambers 23a, 26a and 27a is one foot which provides an equivalent width along the paper web W being dried.
  • the air supplied to the plenum chambers is at about 400 F. ⁇ and the open area of the holes 42 is 2%, then each plenum chamber 23a, 26a ⁇ and 27a has a total drying tarea of 6.3 square feet per foot of width at an air supply of 1890 cubic feet per minute per foot of width, based upon 15,000 feet per minute maximum velocity. Under the exemplary conditions stated, the drying will be about 35 pounds of water per foot of width per hour at 2,000 feet of web per minute. rllhis amounts to about 3% of a sheet weight of approximately 30 lbs.
  • a plenum or Adrying head 44 similar to the plenum 26 and having 6 a perforated plate -29 forming the bottom wall thereof has a bafe member 4S extending transversely thereacross and spaced inwardly of a top svall ⁇ 46 of the plenum 44.
  • the baille member ⁇ 45 is parallel to the perforated y plate 29 and the undersurface thereof is slidably engaged by transverse partition members l#t7 threadably received upon a rod 48 journaled in opposite end walls 49 and 50 of the plenum 44.
  • the threaded rod 48 may be rotated under action of a hand crank ⁇ S1 to move the partition members 47 in a transversely adjustable direction so that heated air from a connecting conduit 52 is impinged against the moving web along a transverse width less than the suggested one foot section.
  • the partition members 47 may be moved transversely under action of motor means, and it is, of course, appreciated that the adjustment means may take forms other than that specifically disclosed in FIGURE 4.
  • fthe web moisture profile control means 17 ⁇ of this invention is provided with transverse partitions 28 in the plenums 23, 2.6 and 27, and damper means 30 in the conduits 22 serving each plenum chamber 23a, 26a land 27a in the plenums.
  • transverse partitions 28 or 47 may be eliminated and the damper means 30 omitted so that uniform volumes of heated air are admitted to each of the plenums 23', 26 .and 27.
  • the air supplied is controlled at a relatively higher humidity, and thereby advantage is taken of the relationships between the equilibruim moisture content of the web and the surrounding vapor conditions of pressure and temperature. This may be shown by the following equation illustrating that the drying rate approaches zero at some definite moisture level above zero, depending upon the temperature of the air and the vapor pressure of the moisture present in the air. This equation is:
  • h heat transfer coefficient, air to sheet, in B.t.u. per
  • the preferred arrangement employs the separating partitions to sectionalize the hood -for zone drying control whereby the paper machine operator, upon detecting moisture streaks in the web, may remotely control the supp-ly of heated air to particular plenum chambers so as to provide in the finished sheet transverse uniformity of moisture content which represented in the plot of moisture profile shows acceptably small irregularities.
  • the hood 17 incorporates in the plenums thereof perforated plates 29 having the nozzle hol-e 'diameter and open area to total yarea relations described, as well as the fan and blower arrangement of 'FIGURE 2 which uses a higher pressure differential as well as slightly sub-atmosphereic pressure in the exhaust system thereof to permit maximum utilization of 7 the heat supplied and limiting the :fan horsepower to an economic level.
  • a drier particularly adapted to ⁇ dry a fibrous Web of material and in combination with a rotatable drying drum having a Web traveling thereabout, a hood extending about Ia portion of the circumference of the drying drum, at least one drying head in said hood having a bottom Wall generally conforming to said drying drum and the web traveling thereabout and having ia plurality of ah impingement nozzles leading therethrough, a plurality vof parallel spaced lbaliies Within :said drying head and conforming to and extending along said bottom Wall in the direction of rotation of said drying drum and dividing said drying head into la plurality of adjacent plenum chambers, an air supply duct, individual conduits leading lfrom said lair supply ⁇ duet to said plenum charnbers, means for supplying heated lair to said air supply duct and withdrawing spent air from said hood, valve means in said conduits operable to control the distribution of air 'across the Iwidth of the web, and
