Description
Technical field
The present invention relates to organic liquid waste processing technology fields more particularly to a kind of utilization supercritical water oxidation to handle organic waste
The control method and system of liquid.
Background technique
It is so-called overcritical, refer to a kind of special state of flowing material.When the fluid increasing temperature and pressure for being in vapor-liquid equilibrium
When, thermal expansion causes fluid density to reduce, and the raising of pressure makes the phase interface of vehicle repair major disappear, and becomes homogeneous system,
Here it is critical points.It is known as when the temperature of fluid, pressure are respectively higher than critical-temperature and critical pressure in supercritical state
State.Supercritical fluid has the good fluidity of similar gas, but density is much larger than gas again, therefore has many unique reasons
Change property.The critical point of water is 374.3 DEG C of temperature, pressure 22.064MPa, if by the temperature of water, pressure rise to critical point
More than, as supercritical water, the basic performances such as density, viscosity, conductivity, dielectric constant have very big difference with light water,
Show the property similar to nonpolar organic compound.Therefore, supercritical water can be with apolar substance (such as hydro carbons) and other
Organic matter dissolves each other completely, and inorganic matter especially salt, the dissociation constant and solubility in supercritical water are but very low.Meanwhile
Supercritical water can dissolve each other completely with gases such as air, oxygen, nitrogen and carbon dioxide.
Supercritical water oxidation (Supercritical Water Oxidation, abbreviation SCWO) technology is a kind of can be achieved
A variety of debirs are carried out with the technology of deep oxidation processing.The principle of supercritical Water Oxidation Technology is with supercritical water for reaction
Organic matter complete oxidation is clean H by homogeneous oxidation reaction by medium2O、CO2And N2Equal substances, S, P etc. are converted into
Highest price salt stabilizes, and heavy metal oxidation stable solid phase is present in ash content.Since supercritical water is equal to organic matter and oxygen
It is fabulous solvent, therefore the oxidation of organic matter can carry out in oxygen-enriched homogeneous phase, there is no because needing alternate turn for reaction
The limitation for moving and generating.Meanwhile 400~600 DEG C of high reaction temperature also accelerates reaction speed, it can be in reaction in several seconds
In, that is, it can reach 99% or more destructive rate.In addition, supercritical water oxidation is to a certain extent and simple burned
Journey is similar, and a large amount of heat is released in oxidation process.
SCWO technology has achieved biggish success in terms of handling various waste water and excess sludge, the disadvantage is that reaction item
Part is harsh and has very strong corrosivity to metal, and also longer to the stable compound oxidation required time of certain chemical property.
Therefore, how using SCWO progress organic liquid waste processing, to accelerate reaction speed, the reduction reaction time, add reaction more
It is of great significance entirely.
