The present disclosure provides a two-stage co-liquefaction mixing-reaction-filtration-heat recovery integrated apparatus, realizing the implementation of a two-stage HTL process; secondly, a nozzle, a receiving chamber, a mixing chamber and a diffusion chamber are disposed at different material feed ports and medium feed ports, and high-speed fluids are fully collided and mixed in these structures; heat of HTL in a first stage is from heat of an HTL product in a second stage, which achieves the recycling of the heat of the HTL product in the second stage, improving economic efficiency; in a first-stage HTL process, through the setting of high-temperature and high-pressure needle valves, so that different first-stage HTL reaction times are selected for different material characteristics; and each first-stage HTL reaction tube is provided with an inclination of 1-3°, and a second-stage HTL generation chamber is provided with a residue scraping device and a salt scraping device.
A two-stage co-liquefaction mixing-reaction-filtration-heat recovery integrated apparatus, comprising a first-stage hydrothermal liquefaction (HTL) generation chamber (19), a second-stage HTL generation chamber (10) and a mid-temperature hydrothermal transition product collection tank (18), wherein one side at a top of the first-stage HTL generation chamber (19) is provided with a plurality of material feed ports and medium feed ports (30), the other side at the top of the first-stage HTL generation chamber (19) is provided with a high-temperature hydrothermal product feed inlet (3), a hydrothermal product discharge port (22) is disposed at the bottom of the first-stage HTL generation chamber (19), a plurality of first-stage HTL reaction tubes (20) are obliquely disposed inside the first-stage HTL generation chamber (19), the plurality of the first-stage HTL reaction tubes (20) are connected in sequence, one end of each of the first-stage HTL reaction tubes (20) extends out through an inner wall of the first-stage HTL generating chamber (19) and is connected to an input end of the mid-temperature hydrothermal transition product collection tank (18), and one end of the first-stage HTL reaction tube (20) at a top is connected to the plurality of the material feed ports and the medium feed port (30);
