Definitions

  • the invention relates to a dust collector with recuperator, in particular a cyclone, which is suitable for the intensive dedusting of gases of high temperature, in particular exhaust gases, for removing the heat content and thereby for lowering the gas temperature.
  • FIG. 230 of the publication mentioned show the changes in the tangential, radial and axial velocities, as well as the total pressure and the static pressure of the gas in different sectional planes of the cyclone.
  • the tangential speed is the lowest along the wall of the cylindrical part of the cyclone and deviates only slightly from the entry speed there. In the conical part, the speed along the wall increases in proportion to the decrease in the radius and reaches the highest value in the vicinity of the dust outlet openings mbi.
  • An axial secondary flow is superposed on the potential eddy current in the plane perpendicular to the axis. The gas flows down the wall and up near the axis.
  • the cooling effect of the air acting on the outer jacket of the cyclone is generally sufficient for cooling gases of higher temperature.
  • GB-A-1 397 892 describes a dust separator based on the cyclone principle, which is used in cement plants and in which the hot cement is cooled by the intensive cooling of the conical collecting space of the cyclone.
  • a container for the cooling water is provided on the side of the conical space or on the outside thereof, in which a constant pressure is ensured.
  • the water, which is under constant pressure, is sprayed onto the surface to be cooled using nozzles.
  • the nozzles are placed at a distance from the surface that allows the formation of a continuous curtain of water from the water jets. The distance between the nozzles and the surface can be changed.
  • the aim of the invention is to create a dust separator which works with swirl and which is suitable for the radical removal of the heat content of gases of high temperature, in particular of exhaust gases, or for lowering their temperature to the desired extent.
  • Another goal is to increase the effectiveness of dust separation - partly by lowering the temperature, partly by the structural design - but at the same time not fundamentally influencing the internal resistance of the system.
  • the dust separator according to the invention with recuperator, in particular cyclone has a heat exchanger which protrudes into the dust separating space provided in the interior of the housing and is arranged in the swirling space of the downward and upward gas movement and ensures the removal of the cleaned gas.
  • the dust collector with recuperator consists of the cylindrical housing 1, of which the dust collector room 2 is surrounded, the dust collecting space 4 enclosed by the conical jacket 3, the heat exchanger 5 and the device used to remove the dust.
  • the heat exchanger 5 is actually installed instead of the traditional suction pipe, it protrudes into the dust separator chamber 2, whereby it simultaneously fulfills the function of the suction pipe.
  • the heat exchanger 5 is dimensioned and arranged in such a way that it is located in the dust separator chamber 2, which is generated and determined by the downward movement of the dust-containing gas and the upward movement of the dedusted gas and quasi as a separation profile the vortex losses belittles.
  • the heat exchanger 5 is immersed so deeply in the dust separating space 2 that its dimensions enable it to ensure that the temperature is reduced or the amount of heat removed.
  • the dimensions and mainly the immersion depth it must be taken into account that the increase in the dedusting efficiency resulting from the cooling, resulting from the increased ability to remove dust, does not decrease, or only to a small extent, by an increased resistance caused by the heat exchanger 5 becomes.
  • the heat exchanger 5 is preferably designed as a double recuperative heat exchanger and consists of the outer 6 and the inner heat exchange element 7.
  • the outer heat exchange element 6 is designed as a cylindrical double-walled jacket 8 containing the coolant.
  • the inner heat exchange element 7 is formed from the tubes 9, in such a way that to ensure an intensive heat exchange and an increase in the degree of dedusting, a space comes about which, due to the envelope body determined by the bent tubes 9 as is continuously converging and again diverging rotationally symmetrical channel is formed, the tubes 9 in the converging part and in the diverging part of the channel and in the narrowest channel cross-section can be spaced apart.
  • the tubes 9 are connected to the overhead cylindrical double-walled inlet body 11, and with their lower end to the cylindrical collector body 12.
  • the cylindrical collector I body 18 is connected to the double-walled jacket 8, so that there is a flow connection between the outer 6 and the inner heat exchange element 7.
  • the inlet connection 13 is connected to the inlet body 11 of the inner heat exchanger 7, and the outlet connection 14 is connected to the double-walled jacket 8 of the outer heat exchanger 6.
  • the dust-laden hot gas for example exhaust gas, reaches the dust separation space 2 via the tangential gas inlet 15, while the cleaned gas exits upwards via the central gas outlet 16.
  • the hot exhaust gas gives off a part of the heat content to the coolant (water, air) flowing in the outer heat exchanger 6 .
  • the largest part of the dust content of the gas is separated in the dust separation space 2 and settles on the inner surface of the conical shell 8.
  • the dedusting efficiency of the cyclone but still very hot gas flows axially from the bottom upwards, enters the space 10 and flows through the bent tubes 9 and releases part of its heat content again.
  • the cooled and dedusted gas leaves the system via the gas outlet 16.
  • the coolant flows through the inlet connection 13, the inlet body 11, the tubes 9, the cylindrical collecting body 12, the double-walled jacket 8 and the outlet connection 14 and heats up in the heat exchanger 5 which works in countercurrent in this catfish.
  • the heat exchanger can also work in direct current; in this case, the terms have to be interpreted accordingly (instead of inlet connection outlet connection etc.).
  • inner heat exchange element 7 instead of the tubes 9, pockets or other bodies configured in a similar manner, or e.g. a double-walled profile designed as a convergent-divergent nozzle can be used.
  • the outer heat exchange element 6 can also be designed differently.
  • the solution according to the invention can be used advantageously wherever the gas to be cleaned has a significant heat and dust content and simultaneous heat evaluation and dedusting are required. Waste incineration and certain industrial processes such as e.g. ore sintering or cleaning of the exhaust gases from coal-fired boilers are mentioned.
