Definitions

  • the subject of the present invention is an installation for producing hot water or steam, such as a fogging apparatus for bakery ovens, a water heater, a percolator, or any other domestic or industrial installation using steam or hot water.
  • a self-descaling process is known from FR-A-1 112473. It is also possible to largely avoid scaling of the installation by providing, upstream of the latter, a water softener , but in this case, on the one hand, we must face the costs represented by the periodic replacement of the ion exchange resin and, on the other hand, we supply the installation for producing hot water or steam with water whose pH has been changed.
  • the object of the present invention is to remedy these drawbacks by proposing a self-descaling installation which requires no user intervention, no energy input, no chemical product and which is simple and economical.
  • the present invention applies to installations of the type comprising a source of cold water, means for controlling the flow of cold water from said source to a receiver, a receiver heated by suitable means and means for producing hot water or steam supplied with water via said receiver, said receiver further comprising means for evacuation to the sewer, the part of the installation upstream of all heating means being called “ cold zone "(Zf) and the part of the installation downstream of said receiver being called” hot zone "(Zc).
  • the object of the invention is achieved in that it offers an installation characterized in that it comprises in the hot zone, a chamber opening on the one hand into said production zone and, on the other hand , in the sewer and in that the supply line has, in the cold zone, immediately downstream of the control means, a bypass opening into the sewer.
  • the evacuation (s) in the sewer are advantageously open permanently, the flow rate of the evacuation not being significant with respect to the flow rate towards the production area.
  • the evacuation to the sewer of the chamber is done by a tube whose evacuation opening is raised relative to the bottom of the chamber.
  • the chamber contains, opposite its water inlet, a jet breaker capable of storing calories when the chamber is empty and of returning them to the water when the latter is readmitted into said bedroom.
  • a jet breaker capable of storing calories when the chamber is empty and of returning them to the water when the latter is readmitted into said bedroom.
  • the installation includes a cold zone Zf and a hot zone Zc.
  • the term “cold zone” is intended to mean a zone in which the temperature is between ambient temperature and about 35 ° C.
  • a valve 3 controlling the flow of water in the pipe 1 and a bypass 4 joining line 1 to a line 5 for evacuation to the sewer.
  • a chamber 6 is interposed, in the hot zone, between the pipe 1 and the steam production zone 2.
  • This chamber 6 is mounted against the wall of the furnace (not shown) by appropriate fixing means 7.
  • the chamber 6 comprises a water inlet pipe 8, a water outlet pipe 9 extending by a pipe 10, the end of which forms a water spray nozzle, and a pipe 11 joined to a bypass 12 opening into the pipe d 'evacuation to the sewer 5.
  • the pipe 11 projects inside the chamber 6, which has the effect of maintaining a tank bottom 13 as best seen in FIG. 2.
  • a jet breaker 14 is provided directly above the water inlet pipe 8 in the chamber 6.
  • the diameter of the branches 4 and 12 is much smaller than that of the pipe 9, so that the leaks towards the sewer are not significant compared to the flow of water injected into the zone of steam production 2
  • valve 3 When it is desired to produce steam, the valve 3 is opened so that the water is conveyed through line 1 into the chamber 6 from which it emerges through line 10 to be sprayed by the nozzle in the production zone steam 2. A minor amount of water escapes towards the sewer by diversions 4 and 12.
  • the valve 3 When it is desired to interrupt the production of steam, the valve 3 is closed, so that a large part of the water contained in the pipe 1, in the area between the valve 3 and the bypass 4, escapes by this bypass to the evacuation pipe to the sewer 5, while the rest of the water contained in the pipe 1 downstream of the valve 3 and the water contained in the chamber 6 flows by the bypass 12 towards the evacuation pipe to the sewer 5.
  • the bypass 4 When the bypass 4 is empty, air enters the circuit from the pipe 5, which has the effect of facilitating the emptying of the chamber 6 and cooling the valve 3.
  • the chamber 6 empties quickly and the liquid film remaining on its walls evaporates instantly.
  • the mineral salts contained in this liquid film are deposited on the walls of the chamber 6 in the form of a thin film of unstructured tartar.
  • the particles of tartar resting on the bottom are swept away by the turbulence created during the re-admission of water and evacuated like those which come from the deposit of tartar on the other walls of the tank.
  • the hot water does not remain in any part of the installation, a stay which promotes the formation of structured tartar strongly adhering to the walls.
  • the hot water is periodically and rapidly removed, which only allows the formation of an unstructured tartar film easily removable by thermal shock and turbulence.
  • the invention is applicable both to an installation for the discontinuous production of hot water or steam and to an installation for continuous production, as shown in FIG. 3, where the same components are designated by the same references as 'in Figure 1 but accompanied by the prime or second signs.
  • Reference 15 designates a timer actuation mechanism alternately actuating the valves 3 'and 3 ". It is understood that, when the mechanism 15 opens the valve 3', the water enters the chamber 6 'and flows through the line 10 'to the steam production zone 2. When the mechanism 15 closes the valve 3' and opens the valve 3 ", the water enters the chamber 6" and flows through the line 10 "to the steam production 2. In this way, steam is produced continuously in zone 2 while the periodic and alternative interruption of the flow of water in the 6 'and 6 "chambers and the periodic and alternative restoration of this flow in said chambers give the self-scaling effect described in detail with reference to FIGS. 1 and 2.
  • the communication between the pipe 1 and the pipe 5, by branch 4, may not be open permanently, but only when valve 3 is closed.
  • the bypass 12 permanently open could be doubled with a discharge pipe of larger diameter and which can be opened when the valve 3 is closed to increase the speed of evacuation from the tank 6.
