The beneficial effects of the utility model are:
1, the utility model is provided with internal container cylinder in kettle inside, leave certain toroidal cavity between kettle and the internal container cylinder, the two outlet by the internal container cylinder below is communicated with, be reflected in the internal container cylinder and carry out, with regard to the effective problem that solves the high corrosion of kettle wall, can make reactor running for a long time in the environment of supercritical water oxidation like this, improve the security performance of work, prolong service life, reduced use cost greatly.
2, the utility model internal container cylinder hangs or is welded on the end socket, can shut down replacing at any time, has both saved a large amount of quality materials, also is convenient to maintenance, and the cost of reactor is reduced significantly.In addition, be provided with the sealing of twice V-type linear sealing groove between internal container cylinder and the end socket, prevent from effectively to reveal.
3, the utility model kettle lower end is provided with the salt outlet of V-type guide groove, be convenient to inorganic salts are discharged, the following artificial cooling in position in internal container cylinder outlet below can also be formed a subcritical region in addition, inorganic salts are discharged with the form of salt solution, prevent the obstruction of salt outlet.
4, the supercritical fluid after the utility model salt solution separates has been full of the inwall of entire reaction still, no longer included pressure reduction between internal container cylinder and the kettle, so internal container cylinder does not bear pressure, only need bear extreme dielectric corrosion, and the material of internal container cylinder can be decided the corrosion situation of material according to the waste water medium, the material washability is very big, as pottery, alloy, also can select excellent stainless steel etc. for use.
5, the utility model internal container cylinder can adopt the straight barrel structure of annular, also can adopt little broad in the middle and other shape tubes in two, can also adopt square, oval or other prismatic structure, and is easy to use.
6, the utility model is adapted to supercritical water oxidation and handles, and its function admirable, security are good, have good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is the structural representation of autoclave.
Five, the specific embodiment:
Embodiment one: referring to Fig. 1, among the figure, autoclave contains kettle 2 and end socket 11, and the two links together (not drawing among the figure) by bolt, and kettle 2 bottoms are back taper, and salt outlet 1 is positioned at the vertex of a cone place, bottom of back taper, is convenient to salt discharge.End socket 11 is provided with air inlet 8, water inlet 9 and discharge outlet 10, be provided with internal container cylinder 4 in the kettle 1, fixedly connected by bolt 6 with end socket 11 in these internal container cylinder 4 upper ends, leave toroidal cavity between its barrel and kettle 2 inwalls, internal container cylinder 4 lower ending openings, this opening is communicated with toroidal cavity, and air inlet 8, water inlet 9 are communicated with the inner chamber of internal container cylinder 4, and discharge outlet 10 is communicated with toroidal cavity.
Be provided with back-up block 3 between internal container cylinder 4 lower ends and kettle 2 inwalls.Be provided with labyrinth sealing mechanism 7 between internal container cylinder 4 upper ends and the end socket 11.Be provided with sealing gasket 5 between kettle 2 and the end socket 11; Internal container cylinder 4 is made by pottery, alloy or stainless steel, determines as required.
Waste water, the oxidation rate of waste liquid under supercriticality are very fast, just can complete oxidation in seconds or tens of seconds.Therefore, from air inlet 8 aerating oxygens, feed waste water, waste liquid from water inlet 9, waste water, waste liquid enter in the internal container cylinder 4 oxidized rapidly under supercriticality, water with the plug-flow state arrive internal container cylinder 4 and kettle 2 belows be communicated with the place time, oxidizing process is finished, and water has become water purification before the inwall that enters kettle 2.The length of internal container cylinder 4 can be calculated according to the complexity of wastewater through organic matter composition and processing.After treating that organic matter is finished oxidation in internal container cylinder 4, introduce between internal container cylinder 4 outer walls and kettle 2 inwalls, outside delivery port 10 discharge reactors by the supercritical fluid of internal container cylinder 4 lower opening after with oxidation.Inorganic salts enters the salt outlet 1 of kettle 2 bottoms under deposition below the internal container cylinder 4, inorganic salts are discharged.In order to prevent the obstruction of salt outlet 1, the following artificial cooling in position in internal container cylinder 4 openings below can be formed a subcritical region, inorganic salts are discharged outside the reactor with the form of salt solution.Because the supercritical fluid after salt solution separates has been full of the entire reaction still, has no longer included pressure reduction between internal container cylinder 4 and the kettle 2.So internal container cylinder 4 does not bear pressure, only need bear extreme dielectric corrosion.The material of internal container cylinder 4 can be decided the corrosion situation of material according to the waste water medium, and the material washability is very big, as pottery, alloy, also can select excellent stainless steel etc. for use.
The barrel of internal container cylinder 4 can be finished (or square or ellipse and prismatic structure) by little broad in the middle and other the special-shaped tubuloses in the straight barrel structure of annular or two.
