Abstract

Sposób przeprowadzania procesu obróbki cieplnej osadu realizowany w układzie zawierającym co najmniej jeden reaktor (1, 1', 1"), osadu (9), co najmniej jeden wymiennik ciepła (2, 2'), do podgrzewania osadu (9), wydzieloną komorę fermentacji beztlenowej WKF (15), układ pozyskiwania biogazu (3) z WKF (15) oraz silnik kogeneracyjny (4) zasilany biogazem (3) zawierający układ chłodzenia cieczą charakteryzuje się tym, że obejmuje następujące etapy: a) do komory co najmniej jednego reaktora (1, 1', 1") wprowadza się osad (9), b) do jednego lub wielu wymienników ciepła (2, 2', 2") doprowadza się ciepło technologiczne w postaci gorącego płynnego lub gazowego medium, c) następnie osad (9) znajdujący się w komorze co najmniej jednego reaktora (1. 1', 1") podgrzewa przy pomocy medium przeprowadzonego przez jeden lub wiele wymienników ciepła (2, 2', 2") do temperatury w zakresie 40°C do 200°C, przez okres co najmniej 20 minut, d) następnie zhydrolizowany osad (11) lub schłodzony zhydrolizowany osad wyprowadza się z co najmniej jednego reaktora (1, 1', 1") i doprowadza się do wydzielonej komory fermentacyjnej WKF (15) i prowadzi się proces fermentacji, f) z wydzielonej komory fermentacyjnej WKF (15) pozyskuje się biogaz (3) i kieruje się do spalania w kogeneracyjnym silniku (4) w celu wytworzenia energii elektrycznej (12) i ciepła technologicznego. Układ do realizacji sposobu zawiera wymienione w sposobie urządzenia.Method of carrying out the sludge heat treatment process carried out in a system containing at least one reactor (1, 1', 1"), sludge (9), at least one heat exchanger (2, 2'), for heating the sludge (9), a separate chamber anaerobic digestion WKF (15), a system for obtaining biogas (3) from WKF (15) and a cogeneration engine (4) powered by biogas (3) containing a liquid cooling system, characterized in that it includes the following stages: a) to the chamber of at least one reactor (1, 1', 1"), sludge (9) is introduced, b) technological heat is supplied to one or more heat exchangers (2, 2', 2") in the form of a hot liquid or gaseous medium, c) then sludge ( 9) located in the chamber of at least one reactor (1. 1', 1") is heated using a medium passed through one or more heat exchangers (2, 2', 2") to a temperature in the range of 40°C to 200°C , for a period of at least 20 minutes, d) then the hydrolyzed sludge (11) or the cooled hydrolyzed sludge is removed from at least one reactor (1, 1', 1") and fed to a separate WKF digester (15) and carried out fermentation process, f) biogas (3) is obtained from a separate WKF fermentation chamber (15) and directed to combustion in a cogeneration engine (4) to generate electricity (12) and technological heat. The system for carrying out the method includes the devices mentioned in the method.
