Description
described field:
The invention belongs to environment protection and chemical field, a kind of super-critical water treatment reactor particularly utilizing supercritical water to process waste water and dregs unmanageable under different concns as reaction medium, be especially applicable to the technological process utilizing circulating water treatment.
background technology:
Supercritical water is water at temperature and pressure all higher than a kind of special state existing on stagnation point, the glassware for drinking water characteristic that has many and conventional water different in this state, such as all can there is change sharply in density, viscosity, solubleness, thermal capacity, specific inductivity etc.The critical temperature of water is 647.096K, and emergent pressure is 22.064Mpa, and density is in this case 322kgm
3, the glassware for drinking water under this state has high diffusibility, low viscous non-polar solvent, for many organism (as pentane, hexane, benzene, toluene etc.) and gas (as oxygen etc.) can dissolve each other with arbitrary proportion with supercritical water, form single homogeneous system.And for inorganic substance, particularly salt, the solubleness in supercritical water is very low, can separate out after water reaches supercritical state.
Supercritical Water Oxidation Technology is the special property utilizing water had in the supercritical state, makes organism and oxygenant that oxidizing reaction occur rapidly in supercritical water and carrys out thorough decomposing organic matter, it is changed into harmless CO completely

2and H
2the micromolecular compounds such as O.And it is difficult that destroy with those poisonous and hazardous materials for those, supercritical water oxidation also possesses good adaptability, its speed of response is fast, treatment effect is good, heat maintenance reaction can also be produced carry out, be all a very desirable treatment technology a lot of aspect, especially adapt to the industrialization development demand that China is current.
Although supercritical water oxidation method has many advantages, its processing speed is fast, treatment effect is good, but due to the character of water, the enforcement of this technology also has a lot of problem, in these problems of experimental phase because equipment is short for little working time, so easily solve, but what in industrial application, some problems just became seriously gets up, and is wherein in particular in:
1. the etching problem of material: much sewage is different acid-basicity, and also have some mineral ion, such as halogen, sulphur, phosphorus etc., these all can have very large infringement to the long-time running of equipment, especially the operational conditions of High Temperature High Pressure, more serious to the corrosion of equipment, extremely thick wall thickness also makes equipment there is a lot of difficulty in the fabrication process.
2. salt sedimentation problem: most of sewage has inorganic salt and the acid-basicity in various degree of different content, in order to reduce it, often neutralizing treatment is carried out to the corrosion of equipment, this just makes the inorganic salt content in sewage water greatly improve, and the character of supercritical water makes inorganic salt cannot dissolve in water, therefore after reaching supercritical state, just have a large amount of inorganic salt separate out and precipitate, the blocking that the device that induces reaction is imported and exported, this not only have impact on the carrying out of reaction, also equipment can be caused to occur potential safety hazard because the water under supercritical state not easily compresses.
3. economy practical problems: although the treating processes of supercritical water oxidation is exothermic process, need to consume a large amount of heat in the process of device start, and heating after usually pressurization being all through to sewage, heat-processed is so just made to be difficult to be undertaken by naked light, and the heat reclaimed also is difficult to heat sewage, not only increase cost, also waste a large amount of energy.
goal of the invention:

Transverse concave groove i on oxide treatment section ceramic wall 6b outside surface and the quantity of longitudinal fluting j are few compared with the transverse concave groove b of mixing section ceramic wall 6a and longitudinal fluting c, shallow compared with mixing section of the degree of depth, radial direction through hole m is little compared with the radial direction through hole e of mixing section ceramic wall 6b, its object is only used to prevent sewage from contacting with reactor metal wall, therefore the groove of ceramic wall is very shallow, and interval is large, and flow is also little, upper end closes, and recirculated water only enters reactor in centre.The measurement and control of temperature of reaction process, as shown in Figure 1, obtained by the dop of subsidiary temperature probe 12, oxidising process is thermopositive reaction, temperature can raise to some extent, reaction mainly is carried out at mixing section and oxide treatment section, so the temperature recorded at this section is the top temperature of inside reactor, accurate temperature survey also makes the carrying out of reaction be more prone to control.
As shown in Figure 1, circulating water inlet 7 is connected with isocon 12, circulating water inlet 7 and corresponding with mixing section 6a, on upper shell outer wall circulating water intake connect, and isocon 12 and corresponding with oxide treatment section 6b, on upper shell outer wall circulating water intake connect.Mixing section is located in the outlet of circulating water inlet 7, and the outlet of isocon 12 is arranged on oxide treatment section, because the recirculated water introduction volume of mixing section 6a is large, oxide treatment section 6b recirculated water introduction volume is little.
Embodiment 6
As shown in Figure 14,15, ceramic wall 6 is divided into two sections, and epimere is mixing section ceramic wall 6a, and hypomere is oxide treatment section ceramic wall 6b.
Mixing section ceramic wall 6a is made up of mutually nested outer ceramic wall 61 and interior ceramic wall 62, and the structure of outer ceramic wall 61 and interior ceramic wall 62 as shown in figure 13.
Oxide treatment section ceramic wall 6b is made up of mutually nested outer ceramic wall 61 and interior ceramic wall 62, outer ceramic wall 61 is identical with embodiment 5 with the structure of interior ceramic wall 62, misplace between inside and outside ceramic wall 62,61 90 ° of assemblings, the internal diameter that outside the external diameter of ceramic wall 62, ceramic wall 61 equals, meet assembling therebetween, then be fixed on dop 13 by draw-in groove d.
