Abstract
Sposób pirolizy i zgazowywania substancji odpadowych i biomasy, w którym temperature do pirolizy i zgazowywania otrzymuje sie poprzez procesy egzotermiczne charakteryzuje sie tym, ze substancje odpadowe i biomase dostarcza sie bezposrednio do instalacji, gdzie w temperaturze poddaje sie osuszeniu i podgrzaniu do temperatury okolo 70°C a nastepnie przeprowadza sie pirolize w temperaturze 200-800°C uzyskanej poprzez samoczynny egzotermiczny proces rozkladu przetwarzanej masy a nastepnie poddaje sie zgazowaniu w temperaturze 800-950°C uzyskanej poprzez spalanie powstalego wskutek rozkladu gazu syntetycznego, przy czym spalanie gazu syntetycznego przeprowadza sie w odizolowanej od powietrza z zewnatrz komorze paleniskowej, w której gaz podawany jest wraz z powietrzem w proporcjach umozliwiajacych regulacje intensywnosci spalania oraz zawirowanie spalin przy utrzymaniu temperatury co najmniej 1100°C a spalone czastki przebywaly w komorze przez co najmniej 2 sekundy nawet gdy spala sie odpady niebezpieczne o zawartosci zwiazków chlorowcoorganicznych przeliczonych na chlor powyzej 1% po czym spaliny przesyla sie do wymiennika ciepla (4) i ogrzewa sie uzdatniona wode cyrkulujaca w systemie cienkich wysokocisnieniowych rur a w wiekszosci spaliny o temperaturze okolo 450-500°C odbiera sie z wymienników i kieruje do ogrzewania bloku i glowicy silnika parowego a po wyjsciu z silnika parowego czesc powstalego gazu i pary pod cisnieniem 10-12 bar kieruje sie do inzektorów, gdzie jest zasysana przez wode o cisnieniu 60-70 bar i w niej rozpuszcza sie dwutlenek siarki i tlenki azotu, i otrzymuje sie kwas siarkowy i kwas azotowy, zas rozpuszczony w wodzie dwutlenek wegla uwalnia sie za pomoca obnizenia cisnienia wody do poziomu 1-3 bar, zas popioly oraz resztki mineralów i metali nie ulegajacych pirolizie i gazyfikacji, poddaje sie procesowi witryfikacji, polegajacemu na topieniu ich w temperaturze co najmniej 1600°C, a nastepnie gwaltownemu schlodzeniu w wodnej kapieli w temperaturze okolo 100°C, doprowadzajac do powstania granulatu zastyglej masy w postaci kulek.The method of pyrolysis and gasification of waste substances and biomass, in which the temperature for pyrolysis and gasification is obtained by exothermic processes is characterized by the fact that waste substances and biomase are supplied directly to the installation, where at temperature it is dried and heated to a temperature of about 70 ° C and then pyrolysis is carried out at a temperature of 200-800 ° C obtained by the automatic exothermic process of decomposition of the processed mass and then subjected to gasification at a temperature of 800-950 ° C obtained by combustion of the synthetic gas resulting from the decomposition, the combustion of synthetic gas is carried out in an isolated from the air from the outside of the combustion chamber, in which gas is supplied together with air in proportions enabling regulation of combustion intensity and flue gas turbulence while maintaining a temperature of at least 1100 ° C and the burned particles stayed in the chamber for at least 2 seconds even when burning hazardous waste with a content of organic halogen compounds converted to chlorine above 1%, then the exhaust gas is sent to the heat exchanger (4) and the treated circulating water is heated in a system of thin high-pressure pipes and in most flue gas with a temperature of about 450-500 ° C is collected from the exchangers and directs for heating the block and head of the steam engine and after leaving the steam engine part of the resulting gas and steam under 10-12 bar pressure is directed to the injectors, where it is sucked in by water with a pressure of 60-70 bar and in it sulfur dioxide and oxides dissolve nitrogen, and sulfuric acid and nitric acid are obtained, while carbon dioxide dissolved in water is released by lowering the water pressure to a level of 1-3 bar, and ashes and residues of minerals and non-pyrolysis and gasification metals, are subjected to a vitrification process, consisting of by melting them at a temperature of at least 1600 ° C, followed by rapid cooling in a water bath at a temperature of about 100 ° C, leading to the formation of granules, solidified mass in the form of balls.
