Definitions

  • the present invention relates to a steam generating device, in particular for air humidification systems, with a steam boiler which can be connected to a consumer via a steam pipe, which is in flow connection with a fresh water connection via controllable valve means and which opens into a drain line.
  • Steam generating devices of this type are usually connected directly to normal tap water, which passes through suitable supply lines and valve means into a steam cylinder, where it evaporates under the direct action of resistance heating elements. The steam then reaches the consumer via a steam line, for example into a steam distribution pipe of an air humidification system.
  • the drain line is formed by a lifting pipe of a suction lifting device arrangement, the lifting pipe being operatively connected to controllable suction means.
  • Suitable suction means can be pumps, for example be medium.
  • suction means which are operatively connected to the lifting tube comprise a jet pump which is connected to the fresh water connection of the steam boiler and which, on the suction side, opens into the down pipe of the lifting tube with an intake connection in the region of the knee and which via a solenoid valve connects to the fresh water connection connected is.
  • the fresh water connection can be made separately on the steam boiler.
  • the lifting tube of the siphon arrangement permits a significantly simplified embodiment in that the fresh water connection opens into the riser pipe of the lifting tube via a further solenoid valve in the area of the elbow.
  • the lifting tube can also connect the interior of the steam boiler to a lower-level siphon basin provided with a fresh water connection and a waste water connection, the lifting tube then also being operatively connected to controllable suction means.
  • Suction means suitable for this can also be pump means, for example.
  • suction means that are operatively connected to the lifting tube include a jet pump that is connected to the fresh water connection of the steam boiler and that ends on the suction side with an intake port in the knee of the lifting tube and that can be controlled via a valve-controlled normal pressure line.
  • the siphon basin Since there is a need to fill the siphon basin with a sufficient amount of liquid for the suction process, it is also advantageous to avoid multiple fresh water connections if the siphon basin has a fill pipe and the steam boiler has an inlet pipe with a common, controllable inlet solenoid valve closed fresh water connection are connected.
  • a steam boiler 1 which can be connected via a steam pipe 2 to a consumer (not shown in more detail), the contents of which, as a rule normal tap water, can evaporate under the direct action of resistance heating elements 3.
  • the tap water is introduced into the steam boiler 1 from a fresh water connection 13 via an inlet solenoid valve 12 and an inlet pipe 9 ⁇ and via the riser pipe of a lifting pipe 21, which will be described in more detail below.
  • a level control 4 monitors the liquid level in the steam boiler 1 and emits corresponding control signals to a control circuit 16, via which the inlet solenoid valve 12 is closed or opened.
  • a siphon arrangement 20 For emptying resp. Drainage of the steam boiler 1 is now provided according to the invention a siphon arrangement 20, the so-called, aforementioned lifting tube 21 of the interior of the steam boiler 1 with a lower external level, which is indicated by the outlet 23 ⁇ of the down pipe of the lifting tube 21.
  • a closed liquid column can be created in the lifting tube by suctioning in a lifting tube, which creates an overpressure in the tube from the higher level to the lower level side, which causes the liquid in the tube to flow, whereupon the steam boiler empties extremely quickly.
  • a so-called jet pump 28 which receives its drive energy from the incoming fresh water and is connected to the fresh water connection 13 via a solenoid valve 11 ⁇ .
  • this jet pump 28 On the intake side, this jet pump 28 is connected to the down pipe of the lifting tube 21 via an intake connection 29 in the region of the knee 8.
  • the solenoid valve 11 ′ can also be actuated by the control circuit 16 via a control line 7.
  • the inlet solenoid valve 12 is opened, whereupon fresh water can flow in via the down pipe of the lifting tube 21 until the level control 4 interrupts the filling process. If the liquid level in the steam boiler 1 then drops, the level control regulates tion 4 via the control circuit 16, the refilling by opening and closing the inlet solenoid valve 12.
  • the heating elements 3 are first switched off and the inlet solenoid valve 12 is closed. Then the further solenoid valve 11 ⁇ is opened, whereby the jet pump 28 generates a negative pressure on the riser pipe side in the lifting pipe 21, by means of which the water column in the riser pipe is raised until the independent flow in the pipe begins, as described above.
  • the cold fresh water can mix with the boiler water at the boiling point, causing a mixture to flow into the sewage pipe that is less than 60 ° warm.
  • valve II If the valve II prepare is then closed and the steam boiler 1 has emptied, it can be opened for cleaning.
  • the steam generating device in turn comprises the steam boiler 1, which can be connected via the steam pipe 2 to a consumer (not shown in more detail), the content of which, as a rule, a normal line water, can evaporate under the direct effect of resistance heating elements 3.
  • the tap water is also introduced into the steam boiler 1 from a fresh water connection 13 via an inlet solenoid valve 12 and an inlet pipe 9.
  • a level control 4 monitors the liquid level in the steam boiler 1 and emits corresponding control signals to a control circuit 16, via which the inlet solenoid valve 12 is closed or opened.
  • Draining off the steam boiler 1 now connects the lifting tube 21 to the interior of the steam boiler 1 with a lower-level siphon basin 23 provided with a fresh water connection and a waste water connection.
  • the latter is filled with a sufficient amount of water for a suction process, at the level of which the downpipe 24 forming the waste water connection opens .
  • a closed liquid column can be generated in the knee 8 of the lifting tube 21 in the lifting tube, which creates an overpressure in the tube from left to right in the illustration, which causes the liquid in the tube to flow, whereupon the steam boiler moves extremely quickly emptied.
  • the contents of the kettle flow out through the downpipe 24 at the level of the siphon basin 23.
  • a jet pump 28 is again provided, which derives its drive energy from the incoming fresh receives water and is thus turned on in the inlet pipe 9 for the steam boiler 1.
  • this jet pump 28 is connected to the knee 8 of the lifting tube 21 via an intake connector 29.
  • the function is controlled in the simplest way via a normal pressure line 6 which opens into the intake port 29 and which can be closed by a solenoid valve 11 in order to initiate the intake process.
  • This solenoid valve 11 can also be actuated by the control circuit 16 via a control line 7.
  • the aforementioned fresh water connection 13 also serves to fill the siphon basin 23, for which purpose a branch line in the form of a filling line 22 for the siphon basin 23 is connected downstream of the inlet solenoid valve 12. In order to take into account a smaller fill quantity here, a throttle device 15 is switched on in this fill line 22.
  • the inlet solenoid valve 12 is opened, whereupon fresh water can flow in until the level control 4 interrupts the filling process.
  • the siphon basin 23 is also filled via the filling line 22. If the liquid level in the steam boiler 1 then drops, the level control 4 regulates the refilling via the control circuit 16 by opening and closing the inlet solenoid valve 12.
  • the heating elements 3 are also switched off here first and then the inlet solenoid valve 12 is initially opened.
  • Fresh water thus reaches the steam boiler 1 via the inlet pipe 9 opening out near the bottom of the boiler and cools the water near the suction opening of the lifting tube 21 near the bottom, whereby the steam generation stops.
  • the solenoid valve 11 is closed, whereby the jet pump 8 generates a negative pressure in the lifting tube 21, by means of which the water columns in the lifting tube 21 are raised until the siphon effect begins as described above. If the inlet valve 12 is then closed and the normal pressure valve 11 is opened, the steam boiler 1 remains essentially empty and can be opened for cleaning.
