Description

Bekannt ist das Sprühtrocknungsverfahren zum Trocknen von Suspensionen, Dispersionen und Solen.
Seither wird die Luft, die dem zu trocknenden Gut (Material) die absolute Feuchtigkeit, also Wasser, entziehen soll, isobar aufgeheizt, bei konstantem Wassergehalt des Trockenluftstromes. Bevor der Trockenluftstrom in die adiabatische (Sprühtrocknung) Wäsche eintritt, muß der Verbrauch von Primärenergie oder elektrischer Energie aufgeheizt werden.The spray drying process for drying suspensions, dispersions and brines is known.
Since then, the air, which is supposed to extract absolute moisture, i.e. water, from the material to be dried, has been heated isobarically, with a constant water content of the dry air flow. Before the dry air flow enters the adiabatic (spray drying) laundry, the consumption of primary energy or electrical energy must be heated up.

Damit keine latente Wärme, also Feuchtwärme, in den Trockenluftstrom gelangt, denn die Feuchtigkeit des Produktes soll ja eliminiert werden, scheiden regenerative Energierückgewinnungsanlagen zum reinen isobaren Energierückgewinn mit Feuchtluftleckagerückführung in den Trockenluftstrom aus. Die Erfindung beseitigt diese Mängel und unnötige Energieeinsätze.So there is no latent heat, i.e. damp heat, in the dry air flow reached because the moisture of the product should yes are eliminated, regenerative energy recovery systems to pure isobaric energy recovery with Wet air leakage return to the dry air flow. The invention eliminates these shortcomings and unnecessary energy input.

Claims (4)

Anspruch 1
Das Sprühtrocknungsverfahren ist dadurch gekennzeichnet, daß dem Trockenluftstrom nach der adiabatischen Wäsche im Sprühtrockner Enthalpie über ein Arbeitsmedium oder Wärmeträger im Rekuperator, im Kreuz-, Gleich oder Gegenstrom entzoegen und gleichzeitig dem Trockenluftstrom als sensible Energie zurückgeführt wird. Claim 1
The spray drying process is characterized in that enthalpy is removed from the dry air flow after the adiabatic washing in the spray dryer via a working medium or heat transfer medium in the recuperator, in cross-flow, co-flow or counter-flow and at the same time is returned to the dry air flow as sensitive energy. Anspruch 2
Das Sprühtrocknungsverfahren gemäß Anspruch 1, ist dadurch gekennzeichnet, daß die dem Ventilator zugeführte Entropie zum Fördern des trockenen Luftstromes und des Trockengutes, soweit sie zur sensiblen Temperaturerhöhung wirksam sein kann, dem Trockenluftstrom direkt oder über die Rekuperativenergierückgewinnung zurück- oder hinzugewonnen wird.Claim 2
The spray drying method according to claim 1, characterized in that the entropy supplied to the fan for conveying the dry air flow and the drying material, insofar as it can be effective for sensitive temperature increase, is recovered or recovered directly from the dry air flow or via the recuperative energy recovery. Anspruch 3
dadurch gekennzeichnet, daß gemäß Anspruch 1 und 2 nur die sensible Wärme dem Trockenluftstrom zugeführt wird und gleichzeitig die Trockenluftstromaufheizenergie reduziert wird, unter Energierückgewinnung aller Energieverbraucher im Sprühtrocknungsverfahren, die zur sensiblen und isobaren Temperaturerhöhung des Trockenluftstromes möglich sind.Claim 3
characterized in that according to claims 1 and 2 only the sensitive heat is supplied to the dry air flow and at the same time the dry air flow heating energy is reduced, with energy recovery of all energy consumers in the spray drying process, which are possible for the sensitive and isobaric temperature increase of the dry air flow. Anspruch 4
dadurch gekennzeichnet, daß gemäß Anspruch 1, 2 und 3 die sensible Wärme aus dem Trockengut als sensible Wärme im Trockluftstrom über geeignete Maßnahmen, soweit das sensible Temperaturniveau im Trockengut höher ist als im Trockenluftstrom, und durch deren Entzug keine Kondensation im Trockengut hervorgerufen wird, zur sensiblen Temperaturerhöhung des Trockenlufteintritts in die Anlage ohne Trockengutverlust zugeführt wird.Claim 4
characterized in that, according to claims 1, 2 and 3, the sensible heat from the dry material as sensible heat in the dry air flow by means of suitable measures, insofar as the sensitive temperature level in the dry material is higher than in the dry air flow, and no condensation in the dry material is caused by the withdrawal thereof sensitive increase in temperature of the dry air inlet into the system without loss of dry material is supplied.
