Description

Waste harmlessnessize treatment system by super milled critical water}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detoxifying organic-degradable organic wastes by subcritical water, which is difficult to treat in organic wastes and lacks economic efficiency, and thus has not been treated until now. Molecular compound by detoxification and decomposing process of complex household waste and aromatic organic chlorine compound having banzen ring and chlorine atom with strong dissolving power and diffusing power of subcritical water. It is to create high added value by supplying innovative resources to obtain decomposition products in the form of phase powder, and harming a large amount of organic waste in a short time.

The conventional method of bulk disposal of organic waste has the problem of contaminating groundwater or soil by leachate when landfilled on the ground, and incineration requires vast facilities and energy, and harmful dioxin component during combustion process There have been many problems such as air pollution, biomax residue, and PCB storage of toxic substances due to leakage, and the supercritical water method has been solved.

The organic wastes of the present invention exist in the form of solid, liquid, and gas and may coexist in two states depending on temperature and pressure conditions.

When water is heated and pressurized above a certain temperature pressure, it is in a state having gaseous properties and liquid properties called supercritical water. The water becomes supercritical water at 374 ℃ and 22.1Mpa, and it is activated rapidly due to the great change in density, dielectric constant, ion application degree, and degradability, which are unthinkable at normal temperature and pressure. By applying a subcritical water (250 ℃ ~ 300 ℃, 25Kgf / ㎠ ~ 50Kgf / ㎠) slightly softer than the supercritical water based on the characteristics, the nano water droplet generation of the present invention as a means for solving the above problems In the high pressure boiler of the apparatus, high temperature and high pressure steam of 250 ℃ to 300 ℃ and high pressure of 25Kgf / cm2 to 50Kgf / cm2 generate nano water droplets of microparticles of high temperature and high pressure. If the temperature and pressure are insufficient, install a temperature and pressure booster to increase the temperature of the superheated steam generated in the high pressure boiler.The temperature is increased in the heating heater, and the pressure is increased in the high pressure compression pump. Nanodroplets, which are microparticles of optimum temperature and pressure, are injected through the injection nozzles placed inside the reaction cracker, and are decompressed at the moment of being injected into the reaction cracker to prevent them from exiting the subcritical water state. As a means to set the pressure and keep it constant, the automatic control device is installed in the sub-critical water injection nozzle supply path to install the sub-critical water automatic control valve to continuously overheat when the temperature and pressure of the subcritical water in the reaction cracker are insufficient. When the steam is supplied and the pressure and temperature of the subcritical water state are exceeded, the automatic discharge valve is installed in the steam discharge path of the reactor to discharge the water so that the subcritical water state of the subcritical water in the reactor is kept constant.
The reaction decomposition unit installs a stirring moving device in the space of a cylindrical closed pressure vessel, installs a plurality of injection nozzles on the circumferential surface of the hollow shaft and rotates the subcritical water, and stores the organic waste inside the space of the reactor, and then stirs it. When the subcritical water is sprayed onto the surface of the organic waste housed inside the reactor, the subcritical water has a strong activity of liquid solubility and gas diffusion, and the solubility of salts in the vicinity of 250 ℃ is increased 1,000 times. The organic wastes are hydrolyzed rapidly and the oxidation reaction is strengthened, and even the vangen ring of dioxin polychlorinated biphenyl (PSB) is destroyed immediately to form a device that is harmlessly treated. In order to reduce environmental pollution, it is possible to make a significant contribution to the prevention of environmental pollution.
In the subcritical water system of the present invention, trans oil containing 5 ppm of PCB of polychlorinated biphenyl (PCB) of hardly decomposable organic waste was mixed with wood powder of the decomposition catalyst and weight ratio trans oil 1 in the ratio of wood powder 3. After storing in a sealed reactor inner space and stirring, the subcritical water generator generates a subcritical water with a temperature of 230 ° C. and a pressure of 27 Kgf / ㎠ and maintains a subcritical water state for about 1 hour through a spray nozzle installed inside the reactor. After disintegration by spraying, the decomposed processed material was taken out and analyzed. As a result, in the treated solid, the content of PCB became 0.0005ml / l, which was much less than the regulated value of 0.003ml / l. The degradable decomposition of PCB is almost complete, so that solids can be used as compost and fuel charcoal powder.
As mentioned above, PCB disassembly mechanism is generally impossible to decompose when PCB is not more than 1,200 ℃, but it is found that it is decomposed around 200 ℃.
This is because around 200 ℃ and around 1,200 ℃ high temperature is generated. When ultra-energy particles of elementary particles due to phenomena of quantum theory occur at room temperature and local high temperature, if the particles collide with ultra high energy, This high energy is the mechanism that is spent on molecular conversion.
The decomposition technology that generates high energy to decompose the Banshen ring constituting the PCB by generating energy around room temperature, and decomposes the process, adds a wood catalyst to the treated material to more effectively decompose small particles of subcritical water. To promote.
As mentioned above, the subcritical system can be decomposed about 1/4 of the pressure and 1/2 of the temperature of the supercritical system, so comprehensive economic evaluation such as workability, facility cost, and running cost is processed to about 1/3. It is a differentiated system by new technology.

The present invention has a simple structure and is characterized by securing heat resistance, pressure resistance and durability, and makes high value added by making organic waste by detoxifying aromatic organic chlorine compounds, which has been difficult to treat until now. It is also effective in preventing environmental pollution, economics and technical aspects.

Unexplained 26 is the support

                27 indicates decomposition products.

In the present invention as described above, a non-uniform organic waste (not shown) of various types and shapes is added to the crushing mixer 25 installed on the upper inlet 23 of the reaction cracker 5 to be crushed into a predetermined form physically. In order to increase the decomposition efficiency by adding an oxidizing agent and an accelerator at the time of homogeneous mixing, it is introduced into the inlet 23 opened above the reaction cracker 5, and then the cover 24 is closed and the motor 1 is operated. When the chain (4) caught by the chain gear pinion (2) rotates the upper chain gear (3), it is a stirring movement installed in the form of a hollow tube rotating shaft (13) and a radiation type installed in the reaction cracker (5) inner space. When the parlor 14, 14 'rotates, the stirring shaft 6 and the other bearing support 8 support the hollow tube rotating shaft 13 so as to rotate smoothly, and the sealing portion 10 is a hollow tube. The rotating shaft 13 is sealed.

Thus, the high temperature steam generated in the boiler 15 in the process of repeating the stirring movement by the plurality of stirring movement impellers 14 and 14 'in which organic waste rotates in the same direction as the hollow tube rotating shaft 13. After reaching the high pressure compression pump 17 through the connecting pipe 16 and increasing the pressure, the temperature is further increased in the heater 18 to adjust the optimum temperature and pressure for the type of organic waste. ℃ ~ 300 ℃, 25 Kgf / ㎠ ~ 50 Kgf / ㎠) through a swivel joint (19) through a hollow tube of the hollow shaft rotating shaft (13) a plurality of through holes (11), (11) When sprayed onto the organic waste surface by nozzles 12 and 12 'installed in the'), a large amount of heated moisture is circulated at high speed locally and the moisture is also sealed. (5) Inner wall, cover body (7) and discharge door (9) inner surface, such as moving up, down, left, right, agitating, repeated By eliminating dead zones and colliding gradually, forming a space where nano water droplets of subcritical water can penetrate the surface of organic wastes around the treated materials having high affinity with organics. As the number of collision water molecules with a high density of water collides, the number of chlorine atoms is collided, and many of the chlorine atoms are extracted, and the banzen ring of polychlorinated biphenyl (PSB) is repeated. Also, the skeleton including the reaction mixture is completely decomposed and finally detoxify completely to water, carbon dioxide, and hydrogen chloride. A small amount of water generated therein can be discharged through the drain valve 20 on the lower side, and the safety valve 21 on the upper side has a function of adjusting the set temperature so as not to overheat. While obtaining the decomposition product of the reclamation, the motor 1, the boiler 15, the compression pump 17 and the heater 18 are stopped and the pressure relief valve 22 is opened to open the high temperature in the reaction cracker 5, After the high-pressure steam is discharged, the discharge door 9 is opened and taken out.

초임계수나 아임계수 상태에서 분자수는 H₂ O 의 물의 분자로 존재하고 원자수는 H, O, H 의 원자로 존재하고 양자수는 H, O, H 의 양자의 소립자로 존재한다.This is because the nano water of subcritical water impinges on the surface of organic waste, so that the solubility of liquid and gas is strongly activated, and the solubility of salts is increased by 1,000 times around 250 ℃, and organic waste is rapidly hydrolyzed and oxidized. Due to its high reactivity, aromatic organic chlorine compounds of hardly decomposable organic wastes are also decomposed in a short time. This principle is a quantum mathematical theory that hydrolyzes the continuous conversion of molecules, atoms, and quantum atoms of water in the concept of the new triad of water by the generation of high local energy of subcritical water that is slightly softer than supercritical water. Is applied,
Water is composed of hydrogen and oxygen, and when the quantum level of water recovers symmetry, the atomic conversion theory of quantum number connection that occurs in the quantum electron field causes the quantum level number to be symmetric. The concept of the new water tritium of water in the direction of recovery is that the number of molecules ↔ atom ↔ quantum is reversibly changed, resulting in the difference in energy between the quantum and the number of atoms. Is a theory in which molecular conversion is decomposed by atomic conversion of quantum number linkages occurring endothermically and exothermically,
The new concept of water is a phenomenon in which water is a factor of thermal energy, which increases the energy level from the number of molecules to the number of atoms and from quantum to quantum, or vice versa. Represents the new longitudinal change of energy, which indicates the high longitudinal energy change of the energy level.
Atomic conversion occurs continuously as the energy difference of quantum number-atomic number, and molecular conversion occurs as energy difference of atomic-molecular number.
It is well known that the conventional three-phase concept of water represents the three-phase state of a solid (ice) liquid (water) gas (water vapor) by converting its form of presence with temperature. Such a phenomenon has shown the energy change of the horizontal direction with a low energy level. In this way, water is a new concept of quantum mathematics in which quantum mathematics is the theory that the atomic conversion of molecules, atoms, and protons is continuously converted and decomposed by the difference in energy levels.
The conceptual diagram of Sinsu Samtae is as follows.

1) Quantum number: A group of small particles that become molecular number through atomic number when their energy level is lowered.
2) (quantum number-number of atoms): energy at the quantum level contributes to the atomic conversion.
3) (Atom Number-Molecular Number): Atomic level energy contributes to molecular conversion.
In supercritical or subcritical water, the number of molecules is present as a molecule of water of H ₂ O, the number of atoms is present as atoms of H, O, H, and the number of atoms is present as small particles of both H, O, and H.
