Definitions

  • the invention relates to a centrifugal droplet separator for separating liquid droplets from a feed gas stream containing them.
  • Centrifugal droplet separators also referred to as cyclones, are known in the art and are used, for example, for separating liquid droplets from gas streams containing them.
  • Centrifugal drop separators are rotationally symmetrical apparatus, usually with a vertical axis of rotation, often predominantly cylindrical apparatuses.
  • By tangentially introducing the biphasic liquid / gas mixture to be separated it is imparted a helical motion along the inner wall of the apparatus, whereby separation of the components of the mixture as a function of their density occurs under the action of the centrifugal force.
  • the heavier liquid droplets are deposited from the gas on the inner walls of the Zentrifugaltropfenabscheiders, accumulate in the lower part of the apparatus and are discharged through a discharge nozzle.
  • droplets with a mean diameter ⁇ 5 ⁇ m with a probability of 50% and droplets with a mean diameter ⁇ 12 ⁇ m with a probability of> 99% are deposited in the centrifugal droplet separator.
  • the problem may arise that deposit the liquid droplets or solid crusts on the inner walls of the apparatus, no longer run through the discharge nozzle, so that it to fowling associated with a worsening deposition and finally flooding the apparatus.
  • a discontinuous or a continuous cleaning of the apparatus described above by spraying a rinsing liquid by means of spray nozzles.
  • the cleaning success is not always guaranteed, since solids are trapped in protected areas, for example in louvers in lamella separators or in a wire mesh, and thus often can not be discharged.
  • the rinsing liquid must be dispersed in the gas stream and also be separated therefrom.
  • the FR 2 147 545 describes a Zentrifugaltropfenabscheider for cleaning a gas with tangential supply thereof in the lower, conically shaped portion of the centrifugal separator, and with supply of an auxiliary gas stream in the region of the outlet of the purified gas through tangentially arranged supply ports, wherein the auxiliary gas flow in countercurrent to the flow direction of the gas to be cleaned is supplied.
  • the centrifugal separator is supplied.
  • the gas stream to be purified and the auxiliary gas stream are guided in opposite directions of rotation, but not in the same direction of rotation as in the method of the present invention.
  • the object is achieved by a Zentrifugaltropfenabscheider for separating liquid droplets from a feed gas stream containing them, with vertical longitudinal axis and circular cross-section, with a jacket and hoods at the top and at the bottom of the shell, with tangential supply of the liquid droplets containing feed gas stream on the jacket and with a discharge nozzle for the liquid separated in the centrifugal droplet separator in the region of the lower hood and with a gas outlet nozzle for the gas stream cleaned in the centrifugal droplet separator in the region of the upper hood, which is characterized in that two, three or more inlet openings arranged symmetrically on the circumference of the upper hood a tangential supply of rinsing liquid, in the same direction as the supply of the liquid droplet-containing feed gas stream, are provided.
  • the liquid preferably runs over an edge so that complete wetting of the wall with rinsing liquid is achieved.
  • the flushing liquid according to the invention is introduced tangentially, and thus to the inner walls of the apparatus, it is directly into the areas where the liquid separates from the mixture to be separated, and does not have to be separated from the mixture. This increases the efficiency and leads to an overall lower energy consumption, since complete wetting of the wall is achieved, dry spots on the wall are avoided and thus crust formation is prevented.
  • liquids are used as the rinsing liquid, which can easily be separated again from the liquid to be separated off from the feed gas stream, and which in particular do not chemically react with it.
  • Solvents for the liquid to be separated from the feed gas stream or the same liquid which can be separated off from the feed gas stream can also be used as the rinsing liquid.
  • the rinsing liquid can be used with or without additives.
  • rinsing liquid can also be a reaction, a chemisorption or a physisorption.
  • water can be used as the rinsing liquid.
  • the inlet openings for the rinsing liquid may have a circular cross-section.
  • the inlet openings for the rinsing liquid are formed with a rectangular cross-section.
  • the lower hood tapers frusto-conically towards the discharge nozzle.
  • the steepness of the truncated cone should be chosen so that the liquid flows freely, i. at higher viscosity of the liquid a greater slope.
  • the cone is very steep.
  • the lower hood may also be flat or designed as a dished bottom.
  • apex cone which may preferably be open at the bottom for reasons of easier manufacture, and at the bottom of the lower hood, perpendicular to the floor and radially Plates arranged, which support a uniform outflow of the liquid and the flow of the réelletParkden mixture in the apparatus do not disturb as possible. In this way non-effluent thrombi are avoided.
  • the diameter of the Apexkegels is advantageously adapted to the inner diameter of the Zentrifugaltropfenabscheiders.
  • the apex cone is formed with a diameter corresponding to 0.6 to 0.8 times the inner diameter of the centrifugal droplet separator.
  • the angle in the tip of the Apexkegels is preferably between 100 and 130 °. However, it is also plate-shaped embodiments - without apex cone - possible.
  • the on the bottom of the lower hood perpendicular to the ground and radially arranged sheets act in particular as a flow breaker.
  • a downwardly open dripping apron is arranged in the region of the upper hood, around the gas outlet nozzle, at which liquid droplets are separated from the gas stream which exits via the gas outlet nozzle and drip back into the apparatus.
  • the drip apron preferably has a length corresponding to 1.2 times the length of the gas outlet nozzle projecting into the apparatus.
  • the upper hood at the periphery of which two, three or more inlet openings are provided for a tangential supply of rinsing liquid, widens frustoconically with respect to the circumference of the jacket, an edge forming at the transition between the jacket and the upper hood the rinse liquid is running.
  • the invention also provides a process for separating liquid droplets from a feed gas stream containing them into a centrifugal droplet separator having a vertical longitudinal axis and a circular cross section, with a jacket and hoods at the top and at the bottom of the jacket, with at least one tangential feed of the liquid droplet containing feed gas stream on the mantle and with a discharge nozzle for the liquid deposited in the centrifugal droplet separator in the region of the lower hood and with a central gas outlet for the gas stream purified in the centrifugal droplet separator in the region of the upper hood, which is characterized in that in the region of the upper hood, over two, three or a plurality of inlet openings arranged symmetrically on the circumference thereof, a flushing liquid being introduced tangentially in the same direction as the feed gas stream containing the liquid droplets.
  • the rinsing liquid can be supplied continuously during the entire duration of the supply of the feed gas stream to be separated.
  • the rinsing liquid is fed discontinuously, at intervals.
  • FIG. 1 shows an embodiment of a centrifugal Tropfenabscheiders invention with sheath 1 and hoods 2 at the top and at the bottom of the shell 1, and with tangential feed 3 for the feed gas stream.
  • Zentrifugaltropfenabscheider liquid is discharged through a discharge nozzle 4 in the region of the lower hood 2 and the purified gas stream via a gas outlet nozzle 7 in the region of the upper hood. 2
  • a bottom open Abtropfschürze 8 is provided in the region of the upper hood 2 in the longitudinal sectional view in FIG. 1 to recognize a tangentially arranged inlet opening 9 for a rinsing liquid.
  • FIG. 2 shows the tangentially arranged in the region of the upper hood 2, for example, three inlet openings 9 for a rinsing liquid.
  • the tangential feed 3 and the central gas outlet nozzle 7 can also be seen.
