Abstract

In a drinks distillery process, a fluid mash of ingredients is heated and subsequently cooled by a heat exchanger which surrenders the heat to water, where the hot water is especially used to heat the next batch of mash. In a drinks distillery process, a fluid mash of ingredients is heated and subsequently cooled by a heat exchanger which surrenders the heat to water, where the hot water is especially used to heat the next batch of mash. Heat extracted from the mash may alternatively be used for space heating purposes.

Description

Grundlagebasis

Das beim Brennen von Maische (Obstler oder Hefe) anfallende Kühlwasser wird produktionsbedingt dem öffentlichen Abwassernetz zugeleitet. Je nach Brand werden ca. 200 bis 280 Liter Kühlwasser mit ca. 80-85°C ohne weitere Wärmenutzung abgeleitet. The cooling water generated when distilling mash (fruit or yeast) is fed to the public sewage network due to production. Depending on the fire, approx. 200 to 280 liters of cooling water with approx. 80-85 ° C derived without further heat use.

Nachstehende Ausarbeitung kommt immer zum Tragen, wenn mehr als 1 Brand ausgeführt werden. The following elaboration always comes into play when more be carried out as 1 fire.

Durch die Abwärmenutzung zur Vorwärmung des nächsten Brandes, erfolgt eine Wärmenutzung die Produktbezogen auch dann zum Einsatz kommt, wenn keine weitere Wärmenutzung erforderlich wird. Z. B. Wärmenutzung für die Hausheizung. By using waste heat to preheat the next fire a heat use the product-related Use comes when no further heat use is required. For example, use of heat for home heating.

Hieraus ergeben sich folgende VorteileThis has the following advantages

  • a) Verringerung der Primär-Heizenergie. a) Reduction of primary heating energy.
  • b) Kostengünstigere Produktion. b) Less expensive production.
  • c) Erhöhung der täglichen Produktion durch Vorwärmung des nächsten Brandes parallel zum laufenden Brand. c) increasing daily production by preheating the next fire parallel to the current fire.
  • d) Ableitung des heißen Kühlwassers nach Wärmeentzug durch Vorwärmung ohne Probleme ins öffentliche Abwassernetz. Temperatur des Kühlwassers nach Wärmenutzung kleiner 50°C. d) Discharge of the hot cooling water after heat extraction Preheating without problems in the public sewage network. Temperature of the cooling water after using heat less than 50 ° C.

Bei Erwärmung der Maische durch die nutzbare Wärme des Kühlwassers ergibt sich eine sinnvolle Wärmerückgewinnung für das Produckt, unabhängig von der bisherigen Wärmerückgewinnung für - eventuell - die Hausheizung. When the mash is heated by the usable heat of the cooling water, this results in sensible heat recovery for the product, regardless of the previous one Heat recovery for - possibly - the house heating.

Hieraus folgt:

  • 1. Verringerung der Primärenergie zur Aufheizung des Brenngutes durch Vorwärmung
  • 2. Energieeinsparung um den Betrag der in der vorgewärmten Maische enthaltenen Wärme.
  • 3. Kostengünstigere Produktion.
  • 4. Erhöhung der Produktion durch mehr Brände je Tag.
Bewertung zu b.) Erwärmung der Maische bis auf annähernd Kühlwassertemperatur.
Q1/2 = (10,05 + 9,33)/2 = 9,69 KW
Qmax. = 9.7 KW
Erwärmung der Maische bis auf ca. 65°C zur Buketterhaltung.
Q3/4 = (8,82 + 7,9)/2 = 8,26 KW
Qmin. = 8,3 KW Bewertung zu c.) Einsparung an Primärenergie nur durch Vorwärmung.
Q alt = 49,50 KW
Q neu = 39,80 KW (49,50 - 9,70)
WRG max.:
WRG = Q alt/Q neu; = 49,50/39,80 = 1,24, entspricht: 24%!
Q alt = 49,50 KW
Q neu = 41,20 KW (49,50 - 8,30)
WRG min.:
WRG = Q alt/Q neu; = 49,50/41,20 = 1,20, entspricht: 20%! Bewertung zu d.) Erhöhung der Produktion durch mehr Brände je Tag.
Produktionssteigung:
Bei WRG max. = N2/N1 = 12/10 = 1,20 = 20%!
Bei WRG min. = N2/N1 = 12/10 = 1,20 = 20%! Grundlage zur Wärmerückgewinnung bei Destillationsanlagen Abfindungsbrennerei: Kesselinhalt 150 Liter. Maischevorwärmer-Auslegung

Wärmedurchgangszahl: K = 235 Kcal/qm × h × grd
(Quelle: Buderus Handbuch; Tabelle, 9.11)
Erforderliche Heizfläche: Q = F × K × delta-t
Aufheizzeit ist ca 40 min.; entspricht dem Zeitraum des Kühlwasserablaufes!
F = Q/(K × delta-t) × 60/40
F = 8027/(235 × 47) × 60/40 =
F = 8027/(11045) × 60/40 =
F = 1,09 qm From this it follows:
  • 1. Reduction of the primary energy for heating the fired material by preheating
  • 2. Energy saving by the amount of heat contained in the preheated mash.
  • 3. Less expensive production.
  • 4. Increase production by more fires per day.
Evaluation of b.) Warming of the mash up to approximately cooling water temperature.
Q1 / 2 = (10.05 + 9.33) / 2 = 9.69 KW
Qmax. = 9.7 KW
Warming the mash up to approx. 65 ° C to maintain the bouquet.
Q3 / 4 = (8.82 + 7.9) / 2 = 8.26 KW
Qmin. = 8.3 KW rating for c.) Saving primary energy only by preheating.

Q new = 39.80 KW (49.50 - 9.70)
Heat recovery max .:
WRG = Q old / Q new; = 49.50 / 39.80 = 1.24, corresponds to: 24%!
Q alt = 49.50 KW
Q new = 41.20 KW (49.50 - 8.30)

Heat transfer coefficient: K = 235 Kcal / qm × h × grd
(Source: Buderus Handbuch; table, 9.11)
Required heating area: Q = F × K × delta-t
Heating up time is approx. 40 min .; corresponds to the period of the cooling water drain!
F = Q / (K x delta-t) x 60/40
F = 8027 / (235 × 47) × 60/40 =

Verkürzung der Brennzeit durch Vorwärmung:
Verkürzung = 49,50/9,33 = 5,30
60/5,3 = 11,30 min. je Brand Shortening the burning time by preheating:
Shortening = 49.50 / 9.33 = 5.30
60 / 5.3 = 11.30 min. per fire

Bei einer Tagesleistung von 10 Bränden ergibt sich somit eine Brennzeitverkürzung von:
Gesamtzeitverkürzung = 10 × 11,30 min. = 110 min./Tag
Mögliche Zusätzliche Brände = 110/(60 - 13) = 2,34
Mindestens: 2 Brände je Tag! With a daily output of 10 fires, the burning time is reduced by:
Total time reduction = 10 × 11.30 min. = 110 min./day
Possible additional fires = 110 / (60 - 13) = 2.34
At least: 2 fires per day!
