Description

Na rysunku przedstawiono tylko jeden reaktor 4 chociaz korzystniej jest stosowac równolegle pewna 35 liczbe takich reaktorów.Reaktor 4 ma srubowe urzadzenie podajace 5 z usu¬ waniem powietrza przez odpowietrznik 6 umieszczony na czesc dlugosci tego urzadzenia.Koncowa czesc urzadzenia 5 stanowi zwykly cylin- 40 der usytuowany od wnetrza walczaka reaktora z zawo¬ rem jednokierunkowym.Reaktor 4 jest dlugim cylindrem, który w celu umozliwienia osiagniecia przez zawartosc temperatury 250°C jest ogrzewany i izolowany. 45 Czas przebywania wynosi mniej niz 20 minut. Cis¬ nienie w reaktonzee nieco przekracza 42 kg/cm2.Wegiel o zmniejszonej zawartosci wody, glównie w postaci bryl, przechodzi przez zakonczenie pretowego przesiewacza 7 do slimakowego przenosnika 8 i jest 50 wyladowywany w cisnienie atmosferyczne przez urza¬ dzenie hamujace.Faza plynna, przeplywajaca przez przesiewacz 7 za¬ wiera mialki wegiel i przechodzi przez hydrocyklon 9, gdzie wytwarzany jest szlam, który jest nastepnie od- 55 wadniany za pomoca filtru bebnowego 10 i powraca do obiegu.Zastosowanie powyzszego sposobu do usuwania wody ze stalych materialów organicznych innych niz wegiel brunatny bedzie dla fachowców oczywiste i wynalazek 60 zawiera równiez takie zastosowanie. PL PLOnly one reactor 4 is shown in the figure, although it is preferable to use a number of such reactors in parallel. The reactor 4 has a screw feed device 5 with air removal through an air vent 6 arranged part of the length of this device. The end of the device 5 is a normal cylinder. situated on the inside of the reactor drum with a non-return valve. The reactor 4 is a long cylinder which is heated and insulated to enable its contents to reach 250 ° C. The residence time is less than 20 minutes. The pressure in the reactor is slightly higher than 42 kg / cm 2. Coal with a reduced water content, mainly in the form of lumps, passes through the end of the bar screen 7 into the screw conveyor 8 and is discharged at atmospheric pressure by a brake device. through the sifter 7 it contains coal fines and passes through the hydrocyclone 9, where sludge is produced, which is then drained by the drum filter 10 and recycled. Using the above method to remove water from solid organic materials other than brown coal it will be apparent to those skilled in the art and the invention 60 also includes such use. PL PL

Claims

1. Claims 1. Method for dewatering organic materials in solid state, in particular brown coal, characterized in that the dewatered organic material is subjected to an increased temperature in the presence of a medium, at a pressure exceeding the saturation pressure but lower than 350 kg / cm2, after which the liquid water is separated from the material.

2. The method according to claim The process according to claim 1, characterized in that the dewatering is carried out at a temperature of 100-300 ° C, preferably 240-260 ° C.

3. The method according to p. A method according to any one of claims 1-2, characterized in that the dehydration is carried out in the presence of a liquid medium.
