Problems solved by technology

Since the inner diameter of the sludge conveying pipeline 3 is much smaller than the diameter of the tank body, the agitator cannot be installed inside the sludge conveying pipeline 3, so that the sludge is heated unevenly in the sludge conveying pipeline 3, and the sludge is in the sludge Sluggishness is prone to occur in the conveying pipeline 3, and the inner wall is prone to fouling, which further reduces the heat transfer efficiency

Description

technical field [0001] The invention relates to an adjustable continuous thermal hydrolysis device for reducing pipe sludge. Background technique [0002] Thermal hydrolysis device is a commonly used equipment for thermal hydrolysis treatment of municipal sludge. The thermal hydrolysis of sludge refers to: under certain temperature and pressure conditions, the sludge is heated in a closed container to disintegrate the sludge flocs, rupture the cells, release organic matter, hydrolyze macromolecules, and process them through thermal hydrolysis. , can improve the sedimentation performance, dehydration performance and biodegradation performance of the sludge, so as to effectively promote the subsequent anaerobic digestion efficiency. [0003] The Chinese utility model patent with the application number 201220058583.X discloses "A Slurry Reactor for a Sludge Hydrothermal Drying Treatment Device", which describes "a Sludge Hydrothermal Drying Treatment Device". The muddy water ...
