Description

Oppfinnelsen angår en dampgenerator, særlig for ventilasjons— anlegg hvor kjelen er utstyrt med en eller- flere elektriske varmekolber, har kondensavskiller og pressostatregulert damp-laiiaibp, kombinert vannfyIlings- og spyleorgan, samt; elektronisk operasjonsregulering. The invention relates to a steam generator, particularly for ventilation installations where the boiler is equipped with one or more electric heating elements, has a condensate separator and pressure-stat regulated steam inlet, combined water filling and flushing device, as well as; electronic operation regulation.

Et problem ved dampgeneratore ex adr varmekolber og, kjele- under-fardampningsprosessen "blir påfbrt "Ecelegg fra forurensninger og: mineralinnhold i vannet, noe som reduserer varmeelement enes ef-fekt; og medforer hyppig rensing. Kokeprosessen kan også. skape stby, ifall vannivået ikke blir holdt i passe hoydé; over varmekolbene. A problem with steam generators ex adr heating flasks and, the boiler-under-fader steaming process "is caused "Ecelegg from pollutants and: mineral content in the water, which reduces the heating element's effect; and entails frequent cleaning. The cooking process can too. create stby, in case the water level is not kept at the right height; over the heating flasks.

Hensikten med oppfinnelsen er å tilveiebringe en dampgenerator sam er selvrensende samt stoyfri og hvor dets forskjellige funk-sjoner er automatisert via innprogrammert datastyring. The purpose of the invention is to provide a steam generator that is both self-cleaning and noise-free and where its various functions are automated via programmed computer control.

Dette oppnås ifolge oppfinnelsen ved at vannivåe.t i dampgeneratorens kjele under kokeprosessen, kontrolleres av en elektronisk nivåregulator, som holder vannstanden innen bestemte grenser i forhold til varmekoltcene, idet kjelen får vanntilførsel over en magne tven til, via et rorsystem, som samtidig er periodisk spyleorgan for kjele, varmekolber, samt avlbpsventil, når denne åp-nes under rengjbringsprosessen. This is achieved according to the invention by the fact that the water level in the steam generator's boiler during the cooking process is controlled by an electronic level regulator, which keeps the water level within certain limits in relation to the heating coal, as the boiler receives water supply over a large channel, via a rudder system, which is also a periodic flushing device for the boiler, heating flask, as well as the exhaust valve, when this is opened during the cleaning process.

Oppfinnelsen skal beskrives nærmere, under henvisning til teg-ningene : Fig. 1 viser et skjematisk riss av dampgeneratoren med snitt gjennom kjele, isolasjon, stbyskjerm, elektronisk nivåregula—■ tor-, kondensavski "1 1 er, samt sluse ventil. Fig» 2 viser et snitt gjennom kjele, varmekolber, kondensavski Tl er og pressostat, samt stbyskjerm festet til kjelens ende-vegger. The invention shall be described in more detail, with reference to the drawings: Fig. 1 shows a schematic view of the steam generator with a section through the boiler, insulation, steam screen, electronic level regulator, condensation trap "1 1" and sluice valve. Fig» 2 shows a section through the boiler, heating flask, condensation skimmer Tl er and pressure switch, as well as a stby screen attached to the boiler's end walls.

Dampgeneratorens kjele 1 er utstyrt med en eller flere varmekolber 2, har et perforert rorsystem 3 og et spylerbr 12 knyttet til vajminnlbpet 4 via magnetventilen 5, har en stbyskjerm 6 i form.av en krummet stålplate festet til kjelens en-devegger, en pressostat 7 plassert over en kondensavskiller 10 og er dessuten utstyrt med en automatisk åpnings- og luknings-ventil 8 knyttet til avlbpet 11. The steam generator's boiler 1 is equipped with one or more heating flasks 2, has a perforated pipe system 3 and a flushing valve 12 connected to the steam valve 4 via the solenoid valve 5, has a steam shield 6 in the form of a curved steel plate attached to the boiler's end walls, a pressure switch 7 placed above a condensation separator 10 and is also equipped with an automatic opening and closing valve 8 connected to the waste outlet 11.

Kjelen 1 har videre et. overlbp 9, forbundet med avlopet 11 over en elektronisk nivåregulator 15, samt et kondensavlbp 9a knyttet til nivåregulatorens avlopsrbr. Boiler 1 also has a overlbp 9, connected to the drain 11 via an electronic level regulator 15, as well as a condensate drain 9a connected to the level regulator's drain pipe.

Spyleanordningen som består av rorsystemene 3 og 12, får vanntilførsel over magnetventilen 5 og har sitt avlop gjennom utlopsroret 11, som er tilkoblet åpnings- og lukningsventilen 8. Kjelen 1 har dessuten et elektronisk styrt kontrollelement 14 med en foler 13, som åpner avlopsventilen 8 i tilfelle vannivået går over stbyskjermen 6. The flushing device, which consists of the pipe systems 3 and 12, receives water supply via the solenoid valve 5 and has its drain through the outlet pipe 11, which is connected to the opening and closing valve 8. The boiler 1 also has an electronically controlled control element 14 with a feeler 13, which opens the drain valve 8 in in case the water level exceeds the stby screen 6.

Dampgeneratoren virker på fblgende måte, når den for eksempel benyttes i et ventilasjonsanlegg: Slåes strbmmen på, kobles den elektroniske styreanordning inn i samsvar med programmeringen. Avlopsventilen 8 lukkes, mens magnetventilen 5 åpner for vanntilfbrsen til kjelen 1 gjennom rørsystemet 3 og 12 til den hbyde nivåregulatoren 15 angir, i forhold til varmekolbene 2. Kokeprosessen trær i funksjon og vannet oppvarmes under det trykk pressostaten 7 er innstilt for. Den krumme stålplaten 6 skjermer for stby under prosessen, dampen stiger opp langs kjelens sidevegger, passerer kondens-avskilleren 10 og pressostaten 7, idet kondensvannet fores tilbake til kjelen 1 via avlopet 9a. The steam generator works in the following way, when it is used, for example, in a ventilation system: If the power is switched on, the electronic control device is switched on in accordance with the programming. The drain valve 8 is closed, while the solenoid valve 5 opens for the water supply to the boiler 1 through the pipe system 3 and 12 to the high level regulator 15 indicates, in relation to the heating flasks 2. The boiling process starts and the water is heated under the pressure the pressure switch 7 is set for. The curved steel plate 6 screens for stby during the process, the steam rises along the side walls of the boiler, passes the condensation separator 10 and the pressostat 7, as the condensed water is fed back to the boiler 1 via the drain 9a.

Den elektroniske nivåmåler 15 holler vannstanden i kjelen in-nenfor et begrenset område a-b ved periodisk åpning og lukning av magnetventilen 5, i forhold til effekten i varmeelementene 2. Skal varmekolber, kjele og stbyskjerm samt avlbp rengjbres, åpner den elektroniske styreanordning avlopsventilen 8, magnetventilen 5 åpner for spylevannet via rbrsystemet 3 og 12, mens varmeelementene 2 fortsatt er i funksjon. Forurensnin-gene skaller av idet rengjbringsprosessen gjennomfbres ved innprogrammerte intervall. Ved avslutningen lukkes avlopsventilen 8, vannfylling og dampproduksjon settes i gang i samsvar med programmeringen, slik det tidligere er beskrevet. The electronic level gauge 15 keeps the water level in the boiler within a limited range a-b by periodically opening and closing the solenoid valve 5, in relation to the effect in the heating elements 2. If the heating flask, boiler and steam screen as well as the drain are to be cleaned, the electronic control device opens the drain valve 8, the solenoid valve 5 opens for the flushing water via the pipe system 3 and 12, while the heating elements 2 are still in operation. The contamination peels off as the cleaning process is carried out at programmed intervals. At the end, the drain valve 8 is closed, water filling and steam production are started in accordance with the programming, as previously described.

Skulle nivåregulatoren svikte og kjelen bli overfylt, vil fbleren 13 via kontrollelementet 14 åpne avlopsventilen 8 og samtidig varsle med lyssignal, at dampgeneratoren er ute av funksjon. Should the level regulator fail and the boiler become overfilled, the fbler 13 via the control element 14 will open the drain valve 8 and at the same time notify with a light signal that the steam generator is out of order.
