1Oi / OUÖ 1 2 A pre-patent claim is required to carry out the procedure: direction suitable, the diffusion or wash-out tubs and a distillery connected to them Process for the treatment of the distillation column as well as one for the production of Sch'lemweingewein connected as residues 5 pen outlet of the distillation column Pomace and pomace washing water, from which the processing container with a device for alcohol is separated by distillation, bringing treatment chemicals into the characterized in that the at container and with a fume extractor for arising from the distillation, possibly with the vapors rising in the container. To the Ammonium phosphate or calcium carbonate are also used in the processing tank added stillage with a washing water pipe leading to a temperature of about wash-out tubs 80 ° C under guidance in the circuit between a dip tube with a pump basket and a Connected to a distillation column and a wash tub delivery pump. is used. . The method according to the invention and the to 15 its implementation suitable device are explained in more detail below with reference to the drawing. A processing vessel 1 is at the mash or. Schlempeauslaß 7 of a distillation column 6 connected. The container'1 is made of cement The invention relates to a method for handling 2 ° or preferably made of metal and has a socket that in the case of spirits recovery as return assets, which is half of the volume of in remaining pomace and pomace washing water, raw materials distilled 24 hours (e.g. pomace out to which the alcohol is separated by distillation (washing) corresponds. The connecting line between Q will. ■ the column 6 and the container 1 is with a In such processes, there are generally * 5 filling funnels provided, through which, if necessary large amounts of wastewater, which only if it is, depending on the acidity of the stillage (or the clean or neutral wastewater, red or white pomace washing) the required Discharge chemicals, such as ammonium phosphate, into rivers or other bodies of water without damage can be directed. Numerous sewage, e.g. B. the or calcium carbonate, introduced into the container 1 of companies classified as "dangerous" can meet 3 °. However, this condition does not, but rather lead to The container 1 also has a funnel-shaped Water pollution, fish deaths or other- extractor hood 2 and a submersible pipe with pump basket 3 ren damage. on. A pump 4 is attached to the immersion tube. In a known method of extraction, the wastewater or the stillage closed the alcohol contained in fermented wine pomace 35 is pumped out and via an outlet line to various the pomace is supplied by extraction with cold diffusion or wash-out tubs in which Water leached out, and this alcohol-containing liquid - for example pomace or similar rawness will be located in rectifiers in a working material. processed on pure fuel. The with water As can be seen from the drawing, the Extracted pomace can then be drained off in the usual 40 when draining a wash-out tub 5 Way for cattle feed purposes and the like. Made usable mash or the pomace washing water, apart will. For waste water purification or recycling from the alcohol withdrawal in the distillation column 6, however, no precautions have been taken. be circulated and repeated several times The invention is based on the object of the pomace and pomace washing water from which the pomace and pomace washing water accumulating as residues 45 when rinsing through a wash-out tub 5 or also i'k the production of brandy. It is possible here to separate the pomace alcohol by distillation, to wash it with still about 80 ° C hot stillage so that it is contaminated and carried away, which compared to the previously usual pollution of rivers and other waters, drive the Pomace washing with about 15 ° C warm, as has been the case so far, to make 50 water with certainty, is apparently advantageous. is avoided. In addition, because of the circulation of the According to the invention, this object is achieved by using the pomace washing water or the vinasse of the detachment, that the water accrual during the distillation is practically zero, if necessary with ammonium phosphate or calcium carbonate added stillage with a temperature 55 converting process are used in which of about 80 ° C under guidance in the circuit between except for the washout vats 5 nor Vorratsder Distillation column and a washout vats are provided in which alcohol-containing is used. Through this treatment, one- fluids will be stored. In this case it will on the other hand, the liquid in the pomace and pomace washing water from the storage tubs Alcohol contained except for a negligibly low 60 column 6 delivered, after which the vinasse on the Residual contents obtained, and also a container 1 and one or more washout water pollution belts avoided. vats 5 is returned to the storage container.
