Definitions
- the invention relates to a heat exchanger with a bypass pipe for cooling hot gases from petrochemical plants vaporizing water with the characteristics of the upper grip of the Claim 1.
- a heat exchanger for cooling is hotter Gases from petrochemical plants, such as ammonia, hydrogen or Methanol production plants or coal gasification plants, with Help of evaporating water is known.
- the gas outlet temperature at the gas outlet nozzle keep constant, is parallel to the heat exchanger tubes Bypass tube arranged, in which engages a closure member. ever after the position of the closure member reaches a certain Subset of the gas to be cooled uncooled through the bypass tube in the gas outlet chamber and mixes there inside a mixing tube with the cooled gas.
- the closing organ of known heat exchanger consists of either one Control plate, which is either swiveling or over an outward guided rod is axially displaceable. The in the gas stream lying control plate is subject - due to the nature of Process gases - corrosion as by carburizing, decarburization or other ablation processes.
- the invention is based on the object, the closure member so to design and arrange in the heat exchanger that a Corrosion on the closure member does not occur.
- the serving as a closure member piston is specified in the Cooled way. This will ensure that the metal temperature of the piston is outside the temperature range, in which a Process gas-related corrosion such as by carburizing, decarburization or other corrosive erosion processes can occur.
- the illustrated heat exchanger is used for cooling of hot Gases from a petrochemical plant.
- the heat exchanger contains within an outer shell 1 a tube bundle straight heat exchanger tubes 2, the ends of each in a tube plate 3, 4 are held. Close to both ends of the tube bundle to the tube sheets 3, 4 an inlet chamber 5 and an outlet chamber 6, which with an inlet nozzle 7 or an outlet nozzle 8 for the supply of the gas to be cooled or the discharge the cooled gas are provided.
- the space enclosed by the tube sheets 3, 4 and the jacket 1 is with a nozzle 9 for feeding and with a nozzle 10 for discharge a heat exchange medium provided.
- a heat exchange medium is used evaporating water.
- bypass pipe 11 Approximately in the middle and parallel to the heat exchanger tubes 2 is through the Heat exchanger a bypass pipe 11 out.
- the bypass pipe 11 penetrates the tube sheets 3, 4 and connects the inlet chamber. 5 with the outlet chamber 6.
- the bypass tube 11 has a larger one Cross section as the heat exchanger tubes. 2
- the outlet end of the bypass tube 11 projects into the Exit chamber 6 into it and is there with a cylindrical Guide tube 12 is connected, which is perpendicular to the longitudinal axis of the Bypass tube 11 runs.
- the guide tube 12 is coaxial with the Outlet nozzle 8 is arranged, wherein between the outlet end the guide tube 12 and the entrance end of Outlet stub 8 an axial distance is present.
- a piston 13 axially arranged slidably, as a closure member for the Bypass tube 11 is used.
- a rearward Actuating rod 14 attached by the wall of the Outlet chamber 6 out to the heat exchanger and provided there with an actuator, not shown.
- the piston 13 is designed as a double-walled hollow cylinder, in the interior of a core 16 made of a ceramic refractory mass is arranged. Through the double wall 15 of Pistons 13 are meandering cooling channels 23 passed, the are flowed through by a coolant.
- the cooling channels 23 are connected to a supply line 24, which in the Actuating rod 14 and arranged outside the Outlet chamber 6 is provided with a cooling medium inlet 25.
- the cooling channels terminate in ademediumausberg 26, in the Outlet chamber 6 opens.
- a cylindrical slider 17 is connected via a cantilever 18 with the Actuating rod 14 connected.
- the inner diameter of the cylindrical slider 17 is so much larger than that Outside diameter of the outlet nozzle 8 that the cylindrical Slider can just slide over the outlet nozzle.
- Of the cylindrical slider 17 is within the outlet chamber 6 so arranged that it can overlap the outlet nozzle 8.
- the outer diameter of the guide tube 12 is smaller than that the outlet nozzle 8, it is - as in the drawing shown - the guide tube 12 of an annular, radial surrounded to the guide tube 12 aligned plate 19 whose Outer diameter approximately equal to the inner diameter of the cylindrical slide 17 is, so that the cylindrical Slider 17 can slide over the plate 19.
- the height of the cylindrical slider 17 is slightly larger than the distance of the annular plate 19 from the upper edge of the outlet nozzle 8, but smaller than the protruding into the outlet chamber 6 Height of the outlet nozzle 8.
- the first partial flow 21 flows through the Heat exchanger tubes 2 and is cooled.
- the partial flow 21 passes after flowing through the heat exchanger tubes 2 in the Exit chamber 6.
- the second partial flow 22 flows through the Bypass tube 11, wherein the second partial flow 22 due to the comparatively large diameter of the bypass tube 11 no Cooling experiences.
