Definitions

  • This invention relates to a probe for sampling hot and dust-laden gas, comprising a multi- walled liquid cooled tube which has a sample gas inlet at its front end, a cylindri ⁇ cal interior filter for filtering the sample gas and an outlet for filtered sample gas at its rear end.
  • the probe comprises an outer tube 11 with a flange 12 welded to it.
  • a flange 13 with holes 14 for screws rests on the flange 12 without being fixed thereto.
  • a wall 15 which for example can be a hood or the side wall of a metallurgic vessel or furnace, a kiln, or a flue of any kind for hot dust- laden gas.
  • the probe is then clamped to the wall 15.
  • the outer tube 11 and an inner tube 16 are welded to a bottom ring 17.
  • An intermediate tube 18 extends between the inner and outer tubes 16, 11 without reaching the bottom 17, and the intermediate tube 18 is welded to the rear end of the outer tube 11.
  • the intermediate tube 18 has an annular end piece 19 welded to it to form an internal shoulder that has an O-ring that seals against the inner tube 16.
  • the intermediate tube 18 has a connection 21 that forms an outlet of cooling liquid for ex- ample water
  • the outer tube 11 has a connection 20 that forms an inlet for the cooling liquid
  • the inner tube 16 has a connection 22 that forms an inlet for cleaning gas.
  • the tubes 1 1, 16, 18 form together a multi-walled, liquid-cooled tube 11, 16, 18.
  • a flange 23 is welded to the inner tube 16, and a filtering unit 24 has a flange 25 welded to it.
  • the filtering unit 24 is inserted in the inner tube 16 and fixed thereto by the flanges 23, 25 that are fixed to each other by screws. There is a gasket between the flanges 23, 25.
  • the filtering unit 24 comprises a central tube 27 which has its front end plugged with a plug 28 welded to it.
  • a flange 29 is screwed onto the plug 28.
  • Two flanges 31 and 32 are welded to the central tube 27 and there is a distance tube 33 between the flanges.
  • the flange 25 is welded to the distance tube 33.
  • a sleeve 34 is welded to the central tube 27 and a sleeve 35 slides on the sleeve 34 and there are O-rings that form a seal between the two sleeves 34, 35.
  • a number of tubular ceramic filtering elements 36, 37, 38 are clamped between the flange 29 and the sleeve 35 by means of a spring 39 that takes support against the flange 31. The spring action provides for a tight seal also when the elements of the filtering unit will have various thermal expansion.
  • the central tube 27 has two sets of distance elements 40 that support and centre the ends of the filtering elements 36-38 so that the filtering elements form together a cylin ⁇ dric annular filter and so that there will be an annular space 41 between the filtering elements 36-38 and the central tube 27 and a annular space 42 between the filtering elements 36-38 and the tube 16.
  • the central tube 27 has a plurality of holes 43 and a connection 44 through which filtered sample gas are sucked out and conveyed to a non illustrated analysis apparatus.
  • An electric heating cable 46 has its terminals 47, 48 at the rear of the tube 27 and it extends inside the tube 27 and protrudes through two of the holes in the tube. It is wound around the tube 27 in the space 41 between the tube 27 and the filter 36-38.
  • the probe is easy to dismount since the entire filtering unit 24 can be retracted when the flange 25 has been loosened from the flange 23, and exchange of the filtering unit can be carried out quickly.
  • a typical probe used in metallurgic processes may have a filter (36-38) that has a diameter of 35-40 mm and a total length of 30-40 cm.
  • the filter will normally take up at least 40 %, preferably at least 50 %, of the length of the cooled tube (11, 16, 18) and the filter area will normally be 300-500 cm 2 .
  • the probe has a large filtering area close to the sample gas inlet and the filter can effectively, quickly and simply be cleaned by means of pressure gas which provides for a high degree of availability.
  • the cleansing can be automatized by simple means so that the cleansing is carried out at regular intervals.

Abstract

Une sonde d'échantillonnage de gaz pour gaz chaud chargé de poussières tel que les gaz brûlés dégagés par des procédés métallurgiques comporte un tube refroidi par eau (11, 16, 18) à parois multiples et un organe de filtrage (24) amovible prévu dans ce dernier. Ledit organe de filtrage comprend un tube perforé (27) entouré d'un filtre en céramique (36-38) cylindrique tubulaire. Une grande surface de filtrage à proximité de l'entrée de l'échantillon de gaz, et le nettoyage efficace du filtre et de ladite entrée au moyen d'un jet de gaz permet d'assurer une efficacité de fonctionnement élevée.
