Description

Wynalazek niniejszy dotyczy sposobu przygotowania wegla metoda plawienia.Jak to powszechnie wiadomo, w sposobie tym maja zastosowanie zwykle srodki plawnicze, w szczególnosci zas wody od¬ plywowe z plóczek benzolowych i wytwór¬ ni amon jaku. Pod wzgledem gospodarczym sposób ten wykazuje znaczne niedobory w tych, w praktyce zachodzacych wypadkach, kiedy koksownia i fabryka dostarczajaca srodków plawniczych nile znajduja sie w bezposredniem sasiedztwie ze soba. Ilosci srodków niezbednych do plawienia wegla sa znacznie wieksze, niz przy plawieniu rud, a skoro je trzeba przesylac chociazby tylko na niewielkie odleglosci, okolicznosc ta czyni juz watpliwa zyskownosc obróbki wejgla plawieniem.Wynalazek niniejszy usiluje usunac wskazany brak. W tym celu stosuje sie w charakterze czynnika plawniczeigo slabo o- grzany wegiel badzto ten sam, który pod¬ lega procesowi plawienia, badz tez inne je¬ go gatunki.Sposób ten jest nader latwy do stoso¬ wania w praktyce i polega aa tern, ze w obracajacym sie np. bebnie ogrzewana jest przy niskiej temperaturze odpowiednia i- ilosc wegla. Natenczas na powierzchni po¬ wstaja te same srodki plawnicze, jakie sta¬ nowia skladniki czynne odcieków z plóczek benzolowych lub podobnych. Slabo w tensposób ogrzany wegiel w!prowadza sie do procesu plawienia, przyczem wytworzone powierzchniowo srodki plawnicze pozosta¬ ja czesciowo w zawieszeniu, czesciowo zas * rozpi^czaja sie. ' SMk w ten sposób ogrzany wegiel sta¬ nowi cenna namiastke zwyklych srodków plawniczycih.Wydzielajace sie przy ojgrzewaniu we¬ gla gazy mozna naturalnie korzystnie spo¬ zytkowac. PLThe present invention relates to a method of coal preparation by the method of bleeding. As is well known, the method usually employs surfactants, in particular drainage water from benzol flakes and yak ammonium plants. From an economic point of view, this method shows significant deficiencies in those practical cases where the coking plant and the factory that supplies the plating agents are not directly adjacent to each other. The amounts of the resources needed for coal tearing are much greater than for ores plowing, and since they need to be transported, even if only short distances, this circumstance makes the mining profitability questionable. For this purpose, poorly heated coal is used as the plowing agent, or the same coal that undergoes the plowing process, or other types of it. in a rotating drum, for example, a suitable amount of coal is heated at a low temperature. The same surfactants are then formed on the surface as are the active ingredients in benzole or similar effluents. The weakly heated coal thus leads to the bubbling process, while the surface-produced floatation agents remain partially in suspension, and partially unfasten. The SMk of the coal heated in this way is a valuable substitute for the usual flame retardants. The gases emitted during the heating of coal can naturally be advantageously used. PL
