Description
Znane srodki chemiczne, sluzace do zapobie¬ gania tworzeniu sie kamienia kotlowego we wszelkiego rodzaju wymiennikach ciepla, sa dosc kosztowne, a ponadto wymagaja czesto stoso¬ wania specjalnych urzadzen do równomiernego wprowadzania tych srodków do wody zasilaja¬ cej lub juz zawartej np. w kotle parowym, skra¬ placzu lub podobnym wymienniku ciepla.W mysl wynalazku niedogodnosci tych mozna uniknac, stosujac jako srodek, zapobiegajacy two¬ rzeniu sie kamienia kotlowego w wymiennikach ciepla, bloto defekacyjne, otrzymywane w cu¬ krowniach jako produkt odpadkowy. Bloto defe¬ kacyjne otrzymuje sie, jak wiadomo, przy oczy¬ szczaniu soku cukrowego z buraków za pomoca wapna, które nastepnie wydziela sie w postaci weglanu wapniowego przez nasycenie soku (sa¬ turacje) dwutlenkiem wegla.*) Wlasciciel patentu oswiadczyl, ze twórca wynalazku jest inz. Roman Szarejko.Stwierdzono, ze srodek ten nadaje sie zwlasz¬ cza do zapobiegania tworzeniu sie osadów w rur¬ kach, czyli zarastaniu rurek wyparki, gdy ta pra¬ cuje jako skraplacz pary powrotnej z przeciw- preznej turbiny parowej w tym czasie, gdy tur¬ bina ta sluzy do napedu pradnicy, wytwarzajacej prad w okresie poza kampania. Srodka tego do¬ daje sie równiez do wody ochladzajacej pare powrotna z turbiny, przy czym wode te co pe¬ wien czas usuwa sie z wyparki. Rurki wyparki sa zupelnie czyste nawet po dluzszym okresie pracy wyparki. PLThe known chemicals to prevent the formation of limescale in all kinds of heat exchangers are quite expensive and, moreover, often require the use of special devices for uniform introduction of these agents into the feed water or already contained, for example, in a steam boiler , a condenser or similar heat exchanger. According to the invention, these disadvantages can be avoided by using as a measure to prevent the formation of limescale in heat exchangers, defecation mud, obtained in sugar factories as a waste product. Defining mud is obtained, as is known, when purifying sugar beet juice with lime, which is then released in the form of calcium carbonate by saturating the juice (saturation) with carbon dioxide. *) The proprietor of the patent stated that the inventor of the invention was is Eng. Roman Szarejko. It has been found that this agent is especially suitable for preventing the formation of deposits in the tubes, i.e. fouling of the tubes of the evaporator when it is operated as a condenser for the return steam from the counter-pressure steam turbine at that time, when this turbine is used to drive a generator that produces electricity outside the campaign. This agent is also added to the cooling water of the steam return from the turbine, which water is periodically removed from the evaporator. The evaporator tubes are completely clean even after the evaporator has been operated for a long time. PL
