Definitions

  • Wet scrubber The invention relates to a wet scrubber according to claim 1.
  • Trained as a wave separator wet scrubbers are known for example from JP 2010038548 A.
  • Wet steam, which enters such a wave separator, is guided there in parallel corrugations formed by a plurality of corrugated sheets and subjected to several rapid changes in direction due to the wave profile.
  • Inertia forces urge water droplets in the wet steam against the corrugated iron walls.
  • this Wassertröpf ⁇ chen combine into larger and larger droplets.
  • the gravity, the Oberflä ⁇ voltage and the pulse then drive these drops in appropriately trained pockets of corrugated metal walls, where they are collected and further derived.
  • the separation of water causes the steam flowing out at the other end of the wave separator to have a lower residual moisture compared with the wet steam entering the wave separator.
  • a reduced in its moisture content of the working steam of an energy or process plant leads to an increase in efficiency of the plant.
  • Wellenab- separators are not easy to manufacture and therefore expensive.
  • the object of the invention is to provide a wet scrubber, which has the lowest possible pressure loss, a ⁇ is easy to produce and thus is inexpensive. This object is achieved by the wet scrubber according to claim 1.
  • the invention now consists in a wet scrubber two-piece corrugated sheets having different WEL lenformen and to connect the perforated edges corresponding to corrugated metal walls so and these corrugated metal walls soSENord ⁇ NEN, on the one hand for the flowing wet steam plurality of parallel channels are formed in which the wet steam recurrently subjected to a change in direction and this while still possible low-friction flow through these channels by the perforated flanks of the corrugated sheets for the wet steam form a kind of "trampolines" with which the wet steam is further accelerated in the direction of the subsequent corrugated metal flank, and other of the moisture content of the wet steam, is effectively reduced by heavier water droplets ⁇ separated by the perforated edges of wet steam and resulting in only by joining two corrugated sheets with nearly the same wavelength but different Wellenbie ⁇ conditions Bags are caught.
  • a wet scrubber can be produced particularly simply if the wave crests are bending edges and the bending edges of the two corrugated sheets have different bending angles and the flanks lying between the bent edges form almost flat surfaces. This can be done in the easiest way by regularly bending a flat sheet. n. Advantageous embodiments are given in the dependent claims and 4.
  • FIG. 2 shows a cross section through a channel formed by two corrugated metal walls for carrying wet steam
  • FIG. 3 in perspective an inventive wet scrubber.
  • appropriate joining techniques such as spot welding or gluing two corrugated sheets with different bending angles al and a2 are connected to a corrugated metal wall W with each other.
  • the pockets T for collecting the moisture to be deposited thereby arise when connecting the two corrugated sheets PI and P2 from their geometries with the different bending angles al and a2.
  • FIG 3 shows in perspective an inventive arrangement of a plurality of corrugated metal walls W, which form a plurality of parallel channels K for a wet scrubber for the separation of water from an entering into the wet scrubber and the channels K flowing through wet steam D.
  • Corrugated metal walls each have W bending edges on two underlying ⁇ different union bending angles and between the bending edges flat surfaces as flanks.
  • the flanks of the corrugated sheets directed towards the entering wet steam in this case have perforation surfaces Q, through which water can be mechanically separated from the wet steam D flowing in the channels K and collected in correspondingly formed pockets T between the two corrugated sheets of a corrugated iron wall.

Abstract

L'invention concerne un séparateur par voie humide comprenant une pluralité de parois (W) en tôles ondulées formant des canaux parallèles (K). Aux fins de séparation de l'eau contenue dans une vapeur humide (D) qui entre dans le séparateur par voie humide et circule dans les canaux (K), chaque paroi (W) comporte deux tôles ondulées (P1, P2) disposées parallèlement et liées ensemble de manière régulière, chacune des deux tôles ondulées (P1, P2) étant formée d'un seul tenant sur toute la longueur des canaux; les deux tôles ondulées (P1, P2) présentent des ondulations aux fléchissements différents les uns des autres pour quasiment la même longueur d'ondulation; les fléchissements présentent des crêtes d'ondulations et des flancs situés entre les crêtes d'ondulations, les flancs (P1, P2) des tôles ondulées étant dirigés en direction de la vapeur humide entrante; des surfaces perforées (Q) permettent la séparation de l'eau de la vapeur humide.
