Abstract: An indirect heat transfer supercritical water oxidation system includes a supercritical water oxidation reactant system and an intermediate medium circuit. A control method thereof includes controlling two-process pressure and temperature increase, controlling pressure and temperature decrease and controlling normal operation. The present invention focuses on automatic control strategy of engineering practice of the indirect heat transfer supercritical water oxidation system. The system heating process adopts the idea of circulating heating, which effectively reduces the investment of the heating equipment avoids the mismatch between the working pressure of the two processes, and ensures effectiveness of the heat transfer between supercritical pressure fluid in the inner tube and the outer tube of the preheater/heat exchanger during subsequent heating process. The effective control of a reaction temperature and overpressure protection of critical equipment ensure a process effect and system safety.

Abstract: A near-zero-release treatment system and method for high concentrated organic wastewater is in the chemical engineering and environment protection field, whose core technology is SCWO. The wastewater and sludge are grinded by the homogeneous pump, pressurized by high-pressure plunger pump, transported to successive pipeline for preheating and mixing with the oxygen and undergoes SCWO reaction in the reactor. After pressure release in the pressure relief device, the reacted fluid passes through the self-cleaning filter and gas liquid separator for insoluble solid and gas separation; then enters the MVR for crystallization of the soluble salts to realize near-zero-release of the feeding. The regular water treatment technology (coagulation sedimentation, membrane biotechnology, membrane technology, etc.) is adopted to complement SCWO, which lowers the operating parameters of the reactor and cuts the operating cost by treating the remaining COD with regular water treatment technology.

Abstract: A radial flow hydrothermal reactor for a sludge thermal hydrolysis treatment is provided, relating to a field of sludge reduction treatment. An outer cylinder and an inner cylinder are successively sleeved in a cylindrical body of the reactor. A guiding cylinder is arranged between the outer cylinder and the inner cylinder. Guiding pipes are provided on a sidewall of the guiding cylinder. An agitator is arranged in the inner cylinder, so that sludge has low viscosity and good fluidity after reaching reaction parameters in the inner cylinder. Because an inlet pipe is arranged below the inner cylinder, the sludge enters the inner cylinder from bottom and flows out from top, and the inner cylinder has a diameter not large, which guarantees heating time. Because of a small height-to-diameter ratio of the radial flow hydrothermal reactor, the sludge after heating has the good fluidity, and flows outward radially in a large space of the outer cylinder. With an increased flowing radius, a flowing velocity decreases, and a hydrothermal reaction proceeds continuously, which guarantees reaction time within limited space of the reactor. Thus, the radial flow hydrothermal reactor is able to work continuously and has a compact structure.

Abstract: A supercritical water oxidation treatment system for organic wastewater with a high salinity crystallizes high-salinity wastewater by a low temperature of liquid oxygen, and decreases an inorganic salt content in the wastewater. Under supercritical water conditions, a hydrocyclone (4) separates most precipitated solid salts in the wastewater, so effectively prevents pipes and the tubular reactor (22) after the hydrocyclone (4) from plugging. Inorganic salts are able to be continuously separated from the system by the hydrocyclone (4) at the bottom of a desalination device, In addition, excess oxygen and gaseous products CO2 are recovered by a separation recovery part. The reaction time and the reaction temperature of supercritical water oxidation reaction are lowered due to the installation of a simple post-treatment unit (37). Moreover, the heat of the reactor effluent with a high temperature is recovered in the system, so operation cost of the system is reduced evidently.
