PROCESS AND DEVICE FOR CONTINUOUS THERMAL HYDROLYSIS Russian patent published in 2018 - IPC C02F11/18 

FIELD: chemistry.

SUBSTANCE: invention can be used for sanitary treatment of sludge. Continuous thermal hydrolysis of sludge, comprising the simultaneous injection of pressurized steam (100) into said sludge and the mixing of said sludge with said steam by means of dynamic injector-mixer (4) so as to obtain a single-phase mixture, conveying said single-phase mixture to pressurized tubular reactor (5) and bringing about the plug flow of this mixture in said reactor (5) to enable the thermal hydrolysis of the organic matter present in said sludge. This single-phase mixture is cooled at its outlet from said tubular reactor (5) to a temperature that allows the subsequent digestion of the hydrolysed organic matter that it contains, depressurizing said cooled single-phase mixture.

EFFECT: invention allows the use of smaller reactors, sanitary treatment of the sludge and optimal condensation of the steam in the sludge.
