Definitions

  • the invention relates to an injection cooler for cooling hot steam conducted in a pipeline according to the preamble of claim 1.
  • Known injection coolers usually consist of a housing with an inlet for the cooling water and a projecting into the steam line injection cylinder, which carries a plurality of juxtaposed injection nozzles.
  • a Control spindle out which is mounted with one end in the injection cylinder connected to the housing and there carries a hole cone in the region of the injection nozzles.
  • the spindle is driven. She performs a lifting movement.
  • the stroke position corresponding to a controller signal releases a certain control cross-section in the hole cone for the entry of the cooling water in the cylinder.
  • standard bores are released to the nozzle chambers in the injection nozzles, whereby the water enters the vapor stream.
  • EP 0 682 762 B1 also uses a lifting system for controlling the amount of cooling water, namely a piston rod which is axially guided in a arranged between a water inlet opening and the injection nozzles hollow cylindrical cooling water pipe.
  • the piston rod carries inside a nozzle head end a control piston, which releases the injectors position-dependent or locks.
  • Such injection coolers have the disadvantage that the control piston during its adjusting movement can release the nozzle orifices in turn only on the basis of their respectively struck linear arrangement, ie. the injectors can always be switched from top to bottom or from bottom to top in a fixed order, which unfavorably affects the water distribution within the steam line and thus unfavorable to the cooling of the superheated steam.
  • the seals and guide elements of the piston and the spindle are very heavily stressed due to the usually very high line pressure of 20 bar to over 300 bar, so that the life of the injection cooler is limited. Short maintenance intervals are the result; the operating costs are very high.
  • a separate water pipe is provided for each nozzle, which is arranged between the control element and the injection cylinder.
  • the injection cylinder channels are formed, which leads the cooling water from an associated water pipe to the respectively associated injection nozzle.
  • a piston rod is provided, which carries a control piston in a cylindrical chamber. This releases - depending on the stroke position - the individual water pipes leading to the injection nozzles.
  • the reciprocating piston must always work against the vapor pressure prevailing in the steam line, so that a relief bore is necessary in the connection head of the control element. If all supply lines are closed, there is therefore the danger that, due to the high water pressure, water will always drip from the injection nozzles into the steam line, which has an unfavorable effect on exact regulation of the steam temperature.
  • the injection cylinder must also have a relatively large diameter in order to accommodate the individual supply lines for the injection nozzles can. With a large number of injection nozzles, therefore, the injection cylinder must have a relatively large diameter.
  • the aim of the invention is to avoid these and other disadvantages of the prior art and to provide an improved injection cooler, which is inexpensive by simple means and easy to handle.
  • the aim is in particular a simple and rapid installation and removal.
  • the injection cooler should have a long service life and ensure optimum cooling water distribution.
  • an injection cooler for cooling superheated steam conducted in a pipeline, with an injection cylinder arranged at least in sections in the pipeline, which is provided with a plurality of injection nozzles, with a control element which can be connected to a connection to a coolant supply, wherein a valve arrangement is provided in the control element is with which the coolant supply to the injection nozzles in the injection cylinder is controllable, and with coolant supply lines, which are provided between the injection cylinder and the control element, wherein a separate coolant supply line is provided for each injector, the invention provides that the injection cylinder associated ends of thedeffenzu classroomtechnische are attached to a common first flange plate which is fixable to a receiving surface on the injection cylinder, and that the control member associated ends of thedestoffzu classroomschreiben to a common second Flange plate are fixed, which is fixable to a receiving surface of the control element.
  • the coolant supply lines provided between the injection cylinder and the control element initially ensure that the control element can be arranged at a distance from the injection cylinder and thus outside the steam line.
  • Another advantage of the injection cooler according to the invention is that the injection cylinder can be quickly and easily replaced if necessary, which must be done regularly when very high temperatures and very high pressures prevail within the steam line. By simply removing a flange plate several cooling water supply lines are removed at once, which has a favorable effect on the installation and maintenance costs. Furthermore, it is possible to construct the injection cooler in a modular manner and to design both the injection cylinder and the control element as well as the coolant supply lines combined on both sides via the flange plates as preassembled structural units. Accordingly, the invention provides that the coolant supply lines and the flange plates form an assembly.
  • the injection cylinder has a housing, wherein the receiving surface for the first flange plate is formed on an outer surface of the housing.
  • the flange plates and the coolant supply lines attached thereto are thus mounted on the injection cylinder from the outside. It is further favorable if the housing of the injection cylinder in the area of the receiving surface for the first flange plate in cross-section angular, for example, square, rectangular or polygonal, is formed.
  • the flange plates can therefore rest flat on the housing of the injection cylinder and reliably sealed against the receiving surface and fixed.
  • An important embodiment of the invention provides that a core insert is provided in the housing, wherein in the core insert for each injector a separate Feed channel is formed, which is fluidly connected to the respective associated injection nozzle.
  • a core insert is provided in the housing, wherein in the core insert for each injector a separate Feed channel is formed, which is fluidly connected to the respective associated injection nozzle.
  • the feed channels introduced in the core insert holes and / or introduced into the outer circumference of the core insert grooves can be evenly distributed over the cross section and the circumference of the core insert, so that a relatively large number of channels can be accommodated in the injection cylinder. Because each feed channel can be assigned its own injection nozzle, a corresponding number of injectors can be arranged within the pipeline.
  • the cooling effect of the injection cooler is correspondingly high, at the same time the outer dimensions are relatively low, so that the free cross-section of the steam line is only slightly reduced and the pressure drop within the line is relatively low.
  • each supply channel in the core insert is flow-connected to an associated coolant supply line via an associated opening in the housing and via a recess associated with the respective opening.
  • the core insert is divided in the longitudinal direction of the injection cylinder.
  • the individual sections can be made separately and also be mounted separately in the housing, the core insert is non-positively and / or positively inserted into the housing.
  • the core insert is pressed into the housing or the housing is shrunk onto the core.
  • the service life of the injection cylinder is thereby significantly increased.
  • the maintenance cycles can be significantly extended, which further has a favorable effect on the operating costs.
  • the injection cylinder is provided with at least two receiving surfaces for receiving first flange plates.
  • the housing with three or four receiving surfaces in cross-section is preferably square, while with five or more receiving surfaces a five or hexagonal housing cross-section is used.
  • flange plates with coolant supply lines can be mounted on almost all side surfaces of the injection cylinder. Each flange plate combines several coolant supply lines into groups, which in turn are provided as preassembled units.
  • the injection cylinder can be fixed by means of a flange on the pipe. This also reduces the assembly effort, because complex welds are no longer necessary.
  • the flange connection is, for example, a conventional flange connection, a self-sealing flange closure according to Uhde-Bredtschneider or a detachable connection of rotationally symmetrical components according to the European patents EP 0 775 863 B1 and or EP 1 010 931 B1 by Mr Alfred Schlemmenat, the contents of which are hereby incorporated by reference.
  • the control element has a housing, wherein the receiving surface for the second flange plate is formed on an outer surface of the housing. This makes it possible to attach the coolant supply lines not only quickly and reliably to the injection cylinder, but also to the control element.
  • Whose housing is this formed in the area of the receiving surface for the second flange plate preferably in cross-section angular, for example, square, rectangular or polygonal, so that the flange plates can be placed flat and always find optimal support.
  • the valve arrangement for the injection cooler is formed in the housing of the control element and thus outside the steam pipe. It comprises a control cylinder, which is arranged in the region of the receiving surface in the housing, wherein the control cylinder is movable by means of a control spindle, which protrudes from the end of the housing of the control element. On the control spindle can thus attack a drive, such as a motor, a gear or a lever.

  • control cylinder is rotatably mounted about a longitudinal axis of the housing, wherein the opening cross section of each opening in the housing of the control element is variable by a rotational movement of the control cylinder.
  • the rotational movement ensures that the size of the cross sections of the openings in the housing of the control element are changed by a purely tangential movement.
  • the life of the seals and guide elements within the control element is significantly increased.
  • the space required for the adjusting movement of the control cylinder is very small, which further has a favorable effect on the size of the control element.
  • control openings may be slit-shaped at least in sections. These control slots are offset on the circumference of the control cylinder to each other and at different heights, so that the openings for thedewasserzustory einen are selectively opened and closed successively and symmetrically to each other.
