Abstract
Parný kotol s povzbudenou cirkuláciou, vybavený kotlovým telesom má v zavodňovacích rúrach výparníka ejektorové čerpadlá. Napájacie potruble kotlá je rozdělené na klasická vetvu, vedúcu ku ohrievaču vody a vetvu, vedúcu k tryske ejektorového čerpadla. Dopravny výkon ejektorového čerpadla a tým aj Intenzita cirkulácie okruhom výparníka sú určené množstvom a tlakom napájacej vody, pritekajúcej napájacím potrubím do trysky.Steamed boiler with encouraging circulation equipped with boiler body has in irrigation evaporator tubes ejector pumps. The boiler feed pipe is divided into classic branch leading to water heater a branch leading to the ejector pump nozzle. Transport performance of ejector pump and hence the Circulation Intensity The evaporator is determined by the amount and pressure supply water flowing through the feed pipe into the nozzle.
Description
Vynález sa týká parného kotlá s povzbudenou cirkuláciou, u ktorého sa rieši spdsob zintenzívnenia cirkulácie termodynamického média ejektorovým čerpadlom, umiestneným v spádových rúrach výparníka.The present invention relates to a steam boiler with an enhanced circulation in which a method for intensifying the circulation of a thermodynamic medium by means of an ejector pump located in the downpipes of the evaporator is provided.
U kotlov v súčasnej době projektovaných, sa využívá k povzbudeniu cirkulácie vo výparníkovom systéme cirkulačných čerpadiel, pohádaných elektromotorom. Elektromotor spolu s čerpadlom sa umiestňuje do zavodňovacích rúr kotlá. Takéto riešenie je z hradiska investičných nákladov na kotol náročné a nesie so sebou riziko porúch na motore, alebo vlastnom čerpadle. V prevádzke nemožno výkon čerpadla ovplyvniť — je konštantný. Rovnako je nemožné bez rekonštrukcie tento výkon zmeniť, ak bol nevhodné zvolený.For boilers currently designed, it is used to stimulate circulation in the evaporator system of circulating pumps driven by an electric motor. The electric motor together with the pump is placed in the boiler water pipes. Such a solution is demanding from the point of view of the investment costs for the boiler and carries the risk of engine or pump failure. The pump performance cannot be influenced in operation - it is constant. It is also impossible to change this performance without reconstruction if it was inappropriate.
Uvedené nevýhody odstraňuje parný kotol s povzbudenou cirkuláciou, tvořený napájacím potrubím, zapojeným na ohrievač vody, zaradený před kotlové teleso, spojené zavodňovacími rúrami s výparníkom, podlá vynálezu, ktorého podstata spočívá v tom, že napájacie potrubie kotlá je rozdělené na napájacie potrubie ohrievača vody a napájacie potrubie, spojené s tryskou ejektorového čerpadla, umiestneného v každej, alebo nlektorej zo zavodňovacích rúr.These disadvantages are overcome by a steam-boosted boiler comprising a supply line connected to a water heater upstream of a boiler body connected by irrigation pipes to an evaporator according to the invention, wherein the boiler supply line is divided into a water heater supply line and a supply line connected to the ejector pump nozzle located in each or any of the irrigation tubes.
Pohyblivé časti rotačného čerpadla a jeho elektromotora sú nahradené nepohyblivým ejektorovým čerpadlom. Čerpací účinok nie je vyvodzovaný na úkor mechanickej energie, ale na úkor tlakovej energie časti napájacej vody kotlá. Čerpací účinok ejektorového čerpadla je ovplyvnitelný množstvom a tlakom napájacej vody, privádzanej do jeho trysky.The moving parts of the rotary pump and its electric motor are replaced by a stationary ejector pump. The pumping effect is not at the expense of mechanical energy, but at the expense of the pressure energy of a part of the boiler feed water. The pumping effect of the ejector pump is influenced by the amount and pressure of the feed water supplied to its nozzle.
Příklad konkrétného prevedenia kotlá s povzbudenou cirkuláciou podlá vynálezu je znázorněný na priloženom výkrese. Ejektorové čerpadlo 4, umiestnené v zavodňovacej rúre 6 nasáva prevádzacími rúrami 8 vodu z kotlového telesa 7. Voda je vytláčaná do rúrok výparníka 10 cez rozvádzacie rúry 9. Casť napájacej vody, privádzanej napájacím potrubím 2 ejektrového čerpadla 4 do jeho trysky 5, vytvára potřebný čerpací účinok ejektorového čerpadla 4. Zbytok napájacej vody je z nápajacieho potrubia 1 kotlá vedený napájacím potrubím 3 ohrievača vody cez ohrievač 11 vody do kotlového telesa 7. Tlak vody v napájacom potrubí 2 ejektorového čerpadla 4 je vyšší od tlaku vody v kotlovom telese 7 o tlakové straty, vznikajúce na trase napájacieho potrubia 3 kotlá a v ohrievači 11 vody a potrubí ohriatej vody 12.An example of a particular embodiment of the boosted circulation boiler according to the invention is shown in the attached drawing. The ejector pump 4, located in the irrigation tube 6, draws water from the boiler body 7 through the transfer tubes 8. The water is forced into the evaporator tubes 10 through the distribution tubes 9. Part of the feed water supplied by the supply line 2 of the ejector pump 4 into its nozzle 5 the effect of the ejector pump 4. The rest of the feed water is led from the boiler brewing pipe 1 through the feed line 3 of the water heater through the water heater 11 to the boiler body 7. The water pressure in the feed line 2 of the ejector pump 4 is higher , formed on the route of the boiler feed line 3 and in the water heater 11 and the heated water line 12.
Kotol s povzbudenou cirkuláciou využívajúci ejektorové čerpadlo, možno použil vo všetkých prípadoch, v ktorých sa používá rotačných oběhových čerpadiel.A circulation-enhanced boiler using an ejector pump can be used in all cases where rotary circulation pumps are used.
