Definitions

  • a countercurrent washer for a gas cleaning tower in- . cludes spaced apart trough-shaped sectors arranged at two different levels in the tower. The sectors at each level slope downwardly and outwardly toward the outer wall of the tower, and the spaced apart sectors at one level cover the sector-spaces between the sectors at the other level. Water, which falls on the sectors, drains toward the outer wall of the tower and onto a collector tray disposed beneath the sectors at the lower level.
  • the invention relates to a multistage countercurrent washer subdivided by trays, which are provided with passageways covered by conical hoods.
  • the customary hoods of the passageways of trays of washers ofler a considerable resistance to the ascending gas to be sprayed with the washing liquid.
  • the loss of pressure of the gas is additionally increased by superimposed washing stages.
  • the gas is diverted downwardly by the conical construction of the hood. It is possible to reduce the resistance by increasing the distance of the hood from the opening of the passageway.
  • this is disadvantageous insofar as concerns the height of the stages of the washer, which in turn signifies an increase of the structural height of the entire washer.
  • the invention comprises forming the covering hoods of trough-shaped sectors which overlap with a clearance.
  • the sides of the channel-shaped sectors have a similar construction and angular position. Furthermore, the sectors are connected together in opposed relation in pairs at the apex and two sector pairs are staggered at 90 one over the other.
  • FIGURE 1 is a vertical section through a part of the washer showing the opening of the gas passageway and the covering hood;
  • FIGURE 2 is a top plan view of the covering hood
  • FIGURE 3 is a view of the covering hood in the direction of arrow A of FIGURE 2;
  • FIGURE 4 is aside view of the covering hood of another embodiment.
  • FIGURE 5 is a perspective view of the covering hood corresponding to FIGURE 4.
  • the tray 1 of a section of a washing tower 2 is pro- 3,360,247 Patented Dec. 26, 1967 vided with an opening 3 for the passage of gas from below.
  • a cylindrical nipple 4 extends upwardly from opening 3.
  • Tray 1 is also provided with an opening 5 for passage of the washing liquid to the next washing stage.
  • the washing liquid is supplied through spray nozzles 20 arranged at the top, above the sectors 7, 7a described hereinafter.
  • the opening 3 of the passageway of nipple 4 connected thereto is covered by a hood 6 to prevent the washing liquid from going through the opening 3 of the passageway.
  • the hood 6 consists of sectors 7, 7a, which have upwardly directed sides 8 and a lower trough 9 formed by abutting sides.
  • the opposed sectors 7, 7a are welded together at the apex 10 and are arranged slopingly downward.
  • the interconnected sector pairs 7, 7a are staggered and arranged one above the other so that their sides 8 overlap.
  • the pairs of sectors are supported on the nipple 4 extending above the passageway 3 by supports 11, and the pair of sectors 7a is supported upon the pair of sectors 7, by supports 12.
  • Passageways are formed in this way between the overlapping portion of the sectors. These passageways are directed upwardly as a result of the upwardly directed sides of the sectors so that the gas is subject to a comparatively slight resistance.
  • each setcor 13 is welded to a preferably cylindrical member 18.
  • a counter-current gas washer comprising:
  • each said sector including (i) first and second edge abutting portions that form a trough, said first portion being larger in area than said second portion with (ii) the first portion of one sector overlapping in spaced apart relation the second portion of an adjacent sector;
  • washing liquid means to introduce washing liquid into said first conduit at a level above said sectors whereby said washing liquid contacts said gases flowing via said passages and impinges upon said sectors and is directed outwardly and downwardly via said troughs onto said diaphragm;
  • a countercurrent gas washer comprising:
  • said second sectors each comprising upwardly sloping edge abut- References Cited ting side members forming a downwardly sloping UNITED STATES P S trough, said second pair of sectors being interconnected at an apex on the axis of said first conduit; 10 332,628 12/1885 Thornton (f) said second pair of sectors being disposed in partial 2, 9 Bartolucci 261'109 X overlapping relation to said first pair of sectors and 2 73 541 2 195 Maiman 1 12 forming downwardly and outwardly directed gaseous flow passages, whereby when washing liquid is intro- FOREIGN PATENTS quizted into said first conduit above said sectors, said 15 145,586 6/1962 -R- washing liquid contacts said gases flowing via said passages and impinges on said sectors and is directed RONALD R.
