A kind of supercritical fluid water oxygen wastewater treatment equipment, the supercritical fluid water oxygen wastewater treatment equipment include
Waste water pump 1, oxidation liquid pump 2, pure water pump 3, tubular reactor 4, the waste water pump 1, oxidation liquid pump 2, pure water pump 3 are and preheater
5 pipes access the tubular reactor 4 after connecing, the waste water pump 1, oxidation liquid pump 2, pure water pump 3 delivery outlet be connected to check valve
6, the lower end of tubular reactor 4 is equipped with the cooling chamber 7 being connected to the inner cavity of the tubular reactor 4, cooling chamber 7 and cooler 8
Input end pipe connect, the output end pipe of cooler 8, which connects, accesses gas separator 10 after counterbalance valve 9.Organic matter in waste water is in institute
It states in tubular reactor 4 and oxidation reaction occurs under the oxidant high temperature and pressure of supercritical water, the organic matter in waste water for being
It is oxidized to gaseous state, is separated in gas separator, counterbalance valve 9 is for regulating and controlling the outlet pressure of cooling chamber.Gas passes through gas
Body separator 10 is released, and liquid is released by counterbalance valve 9.
Further, the input terminal of the preheater 5 is equipped with hand-operated valve 11.It timely can be connected and be truncated according to demand liquid
Stream.
Further, the preheating temperature of the preheater 5 is 500 degrees Celsius.Water body is got into supercriticality.The temperature of water body
Degree increases, and pressure also rises with it.
Further, the entrance of the tubular reactor 4 is equipped with the first thermal detector 12, reactor upper, middle and lower portion difference
Equipped with the second thermal detector 13, third thermal detector 14, the 4th thermal detector 15, the upper and lower part of the cooler 8 is equipped with the 5th survey respectively

Control.
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 complete with apolar substance and other organic matters
It dissolves each other entirely, and inorganic matter especially salt, the dissociation constant and solubility in supercritical water are but very low.Meanwhile supercritical water
It can dissolve each other completely with gases such as air, oxygen, nitrogen and carbon dioxide.
Since supercritical water is fabulous solvent to organic matter and oxygen, the oxidation of organic matter can be oxygen-enriched
