The invention discloses a
solid-containing organic
waste treatment and
separation system based on
supercritical water oxidation technology, including a
solid-containing waste pretreatment module, a
solid-containing waste preheating module, an oxidant supply module, a
supercritical water oxidation module, and subsequent products
Temperature and pressure reduction module, subsequent product online separation module. Through screw conveyors, crushers, vibrating screens, iron removers,
grinding pumps and other devices, solid wastes are crushed, screened, and ground in
multiple stages to meet the requirements of
supercritical water oxidation feed. At the same time, by adding
quartz sand to
grind the sedimentary salt that may be generated in the
system, the problems of salt deposition and blockage in heat exchangers, reactors and other equipment are avoided. For the gas-liquid-solid three-phase products after the reaction, a two-stage separation measure combining a three-phase separator and a liquid-solid two-phase separator is adopted. At the same time, the
liquid phase separated by the liquid-solid separator is circulated and separated, which improves the liquid-solid separation. At the same time, the solid residue after the reaction can be used for
brick making, ceramsite making and external sales, etc., which improves the
system economy.
