Problems solved by technology

[0004] In the existing technology, the concentration of sludge is low and its fluidity is poor. The means of adjusting sludge concentration and fluidity are limited, which is easy to cause blockage of the transportation pipe network, and the heat utilization method of the supercritical system is not in the way of sludge modification. applications, energy utilization is limited

Description

technical field [0001] The invention relates to the technical field of supercritical water oxidation, in particular to a supercritical sludge treatment system and treatment method. Background technique [0002] In supercritical water oxidation technology (SCWO), the critical point of water is 374.3°C and 22.05 MPa. If the temperature and pressure of water are raised above the critical point, it is supercritical water (SCW). Its density, Basic properties such as viscosity, conductivity, and dielectric constant are very different from ordinary water, showing properties similar to non-polar organic compounds. Therefore, supercritical water can be completely miscible with non-polar substances (such as hydrocarbons) and other organic substances. At the same time, supercritical water can also be completely miscible with gases such as air, oxygen, nitrogen and carbon dioxide. The ionization constant and solubility in critical water are very low. Utilizing the special properties o...
