Description

Bekanntlich werden zum industriemäßigen Ausfällen' von wasserloslichen Stoffen aus Lösungen, beispielsweise Salz, beheizte Pfannen oder Gefäße verwendet, in denen das Wasser bei Druck um I ata verdampft wird (;I31iblexr, Triplex-Wärmepumpeverfahren sollen hier nicht in Befracht gezogen werden). Das am Boden der Pfanne absitzende Salz u. dgl. wird mittels automatischer Einrichtungen oder von Hand abgezogen. Die Dämpfe, die ungenutzt ins Freie abziehen, bedingen naturgemäß einen schlechten Wärmewirkungsgrad. It is well known that the industrial precipitation of water-soluble Substances from solutions, e.g. salt, heated pans or vessels used, in which the water is evaporated at pressure around I ata (; I31iblexr, triplex heat pump process should not be freighted here). The one that settles on the bottom of the pan Salt and the like are withdrawn by automatic means or by hand. the Vapors that are released into the open without being used naturally result in poor thermal efficiency.

Man hat versucht, dies dadurch zu verbessern, daß man durch bekannte Verdunstungseinrichtungen' (Gradierwerke) die Lösungen anreicherte. Attempts have been made to improve this by using known Evaporation facilities' (graduation towers) enriched the solutions.

Der Erfindung liegt die Aufgabe zugrunde: 1. denbei dem oben geschilderten Prozeß ins Freie~ab: ziehenden Dampf zu sammeln, auf Druck zu bringen und nach Überhitzung zur Kiafierzeugung iff bekannter Weise heranzuziehen; 2. -den Transport des auszubringenden Gutes, z. B. Salz, selbsttätig durch den Druck zu bewirken, wodurch wesentlich Transport- und Bedienungsarbeit erspart wird. The invention is based on the object: 1. those in the above Process in the open ~ from: to collect drawing steam, to bring it to pressure and after overheating to use iff in a known manner for generating kiafi; 2.-the transport of the to be spread Good, e.g. B. Salt, automatically caused by the pressure, which significantly transports and operator work is saved.

Die Verdampfung der Lösung muß dabei''statt in offenen Behältern in Großwasserraumdruckgefäßen erfolgen. Die ausgefällten Stoffe werden inittels bekannter Abschlammeinrichtungen, die von Zeit zu Zeit betätigt werden, ausgebracht und in Silos gedrückt. Durc'h die entsprechend dem Dampfdruck bedingte höhere Temperatur als 100° C, verdampft die stark angereicherte Flüssigkeit bei Austritt. in die Luft vollständig und scheidet dabei die gelösten Stoffe in fester pulverisierter Form aus. Mittels bekannter automatischer Silowaagen kann dann das Gut abgesackt werden. The evaporation of the solution must take place in open containers take place in shell pressure vessels. The precipitated substances are in means known blowdown devices, which are operated from time to time, applied and pressed into silos. Due to the higher temperature due to the vapor pressure than 100 ° C, the highly enriched liquid evaporates when it escapes. in the air completely and separates the dissolved substances in solid, powdered form the end. The goods can then be bagged using known automatic silo scales.

Dadurch also, daß die Ver,dampfung einer Lösung in Gefäßen unter Druck (über 2 atü) statt in offenen Behältern erfolgt, ist es möglich, außer wasserlöslichen Stoffen, z. B. Salz, billige Kraft in bekannter Weise zu gewinnen und den. Transport der ausgefällten Stoffe wesentlich zu vereinfachen. Der aufzuwendende Wärmebedarf ist unter Berüd:sichtagung der Abwärmeverwerfung- wenìg höher als bei offener Verdampfung. Because of the fact that the evaporation of a solution in vessels under Pressure (over 2 atmospheres) instead of in open containers, it is possible, except water-soluble Substances, e.g. B. Salt to gain cheap power in a known manner and the. transport to simplify the precipitated substances significantly. The heat requirement to be used is under consideration of the waste heat rejection - slightly higher than with open evaporation.

Im folgenden ist ein. Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher beschrieben: In einem Kessel 1 wird die Lösung unter Druck über 2 atü erhitzt und der Dampf in bekannter Weise über tJberhitzer's, Turbine 3 zur Kondensation 4 geleitet. Das anfallende Kondensat wird nicht mehr dem Kessel zugeleitet, sondern abgeführt. Die dafür in den Kessel gespeiste Lösung kann durch Abdampf- und Kesselvorwärmer vorgewärmt werden. The following is a. Embodiment with reference to the Drawing described in more detail: In a boiler 1, the solution is under pressure over Heated 2 atmospheres and the steam in a known manner via superheater, turbine 3 to Condensation 4 passed. The resulting condensate is no longer fed to the boiler, but carried away. The solution fed into the boiler for this purpose can be and boiler preheaters are preheated.

Der durc'h die Konzentration nicht mehr in Lösung bleibende Teil der wasserlöslichen Stoffe lagert sich am Kesselboden ab und wird mittels Abschlammeinrichtung 5 zusammen mit Flüssiglit in Silos 6 befördert. Dort verdampft infolge der bei Druck höheren Merdampfungstemperatur die Flüssigkeit, wobei die gelösten Stoffe in fester Form ausfallen. The part that no longer remains in solution due to the concentration the water-soluble substances are deposited on the bottom of the boiler and are removed by means of a blow-down device 5 transported together with molten metal in silos 6. There it evaporates as a result of the pressure higher vaporization temperature of the liquid, with the solutes in solid Fail shape.
