Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for simultaneous incineration of infectious medical waste and general waste discharged from hospitals.

[Prior art]

Claim 1.2.4 Since the conventional furnace for exclusive use of infectious medical waste burns at an internal temperature of 800 to 900 ° C., it is sufficient to incinerate bandages and PVC tubes, but injection needles and metals. And bottles remain with the ash.
Also, since all small furnaces burn on a fixed horizontal grate,
Since the incinerated material is not moved, even if the combustion condition is bad, the fire will not be able to fully go around even if the auxiliary burner is used. Although incinerated, infectious viruses may remain in the injection needles and bottles. In this case, the bacteria are sterilized but not sterilized. The ash and the residue are ashed from the lower part of the furnace manually using a scoop and treated as general waste. It can be said that the treatment of infectious medical waste is incomplete. General garbage such as kitchen waste and medical waste generate hydrogen chloride, oil and fat of organs after surgery, measures against liquids such as blood, etc. The physical properties of the incinerator are largely different, so the structure of the furnace is fundamentally different and it burns at the same time. The current situation is that it cannot be done. In addition, even when using a medical waste dedicated furnace, when the operator incinerates the contents of the incinerator in each case, he incinerates it while dispersing it in the furnace. Due to the inferiority of the equipment, it is inevitable that a dedicated worker requires extra working time and combustion technology. Claim 3 Even a conventional grate made of heat-resistant metal such as cast steel or stainless steel cannot be used for a long period of time because it is softened and deteriorated when heated by an auxiliary combustion burner from above and below at the same time. Under the same conditions, amorphous refractory materials can withstand high temperatures, but are vulnerable to thermal shock due to the rapid rise in the temperature of burner flames, and are liable to break and fall, resulting in poor reliability. Regarding Claim 4, this portion of the conventional one is an ash pool, and unburned ones are only discharged outside the furnace as unburned ones.

According to claim 5, the conventional discharge pusher pushes the force in one direction only, and cannot satisfy the discharge function when ash and residue bite into each other and when the bridge is formed. With respect to claim 6, the ash melting furnace having a large capacity of several tons includes one using electric power such as a carbon electrode rod and plasma generation, and one using LPG and heavy oil as energy after separating ash from metal. When using electricity,
Power consumption is large, 20 kg residue / batch capacity, and even small ones, it is necessary to newly prepare 20 kW of power.
In addition, the separation of ash bottles and metals has the disadvantage that the equipment is unnecessarily large compared to the small processing amount in the case of a small size as in the present case. Regarding claim 7, when the reburn chamber and the cyclone are built in a conventional small-scale furnace, the exhaust gas flows upside down in the reburn chamber and the cyclone. Therefore, the reburn chamber does not fit and the cyclone is installed next to the preferred type. I couldn't do it. Therefore, when the reburn chamber was built in, there were two reburn chambers, and even in the case of a cyclone, it was a double cyclone. Hydrogen chloride and S for claims 8, 9, 10, and 11.
To remove Ox, NOx, and fine dust, there are wet type that uses water to wash smoke, dry hydrogen chloride removal method that blows calcium hydroxide into exhaust gas for reaction, desulfurization, denitration, and electrostatic precipitator. Since there is no legal regulation for small furnaces with a size of less than 2 m ^2, even if it is understood to be harmful, it has been generally considered that it will not be installed because it costs several times as much as the furnace itself. Place calcium hydroxide solidified in a small furnace in the flue,
Although there is a method of causing a natural ventilation reaction, it is not efficient, and if the chlorine content in the combustion product is 5% or more due to an increase in pressure loss as the reaction proceeds, the treatment becomes impossible. Further, replacement requires manual work at a high place, cannot be replaced during operation due to high temperature, and requires cooling time for the second half of rest.

[0005]

[Problems to be Solved by the Invention] Conventionally, infectious medical wastes have been treated by respective specialists by dividing them into various types such as injection needles and post-operative organs. Let's use this as a resource after completely sterilizing the residue such as ash, glass bottles, metals, etc. after incineration by using an incinerator that incorporates a melting device that can safely and unmannedly handle general waste in the hospital premises. It is what In order to sequentially and automatically supply the combustion products placed in the cardboard box and arranged on the charging conveyor in claim 2, it is necessary to grasp the situation inside the furnace. If only general waste, or only incinerated materials that can be identified as the same, is burned, it can be determined that the temperature inside the furnace has decreased. However, in order to suppress the generation of dioxin in the operating conditions of this equipment, there is a problem that this means cannot be used because the temperature inside the furnace is controlled so that it does not always fall below 800 ° C. by interlocking with the auxiliary combustion burner.
It is necessary to grasp the situation inside the furnace reliably regardless of temperature. According to claim 3, since it is overheated by the auxiliary burner from the grate and the auxiliary burner from the bottom of the bed, the temperature becomes high without being cooled by the combustion air from below like a normal incinerator, and it is durable even with stainless steel heat-resistant steel. There are difficulties in sex. Further, even if an amorphous refractory material is used, a crack may occur due to thermal shock due to direct heat of the burner, and the crack may progress to the central portion and finally break. A grate with both heat resistance and toughness is required here. In Claim 4, unburned liquid, fluidized polymer resins, and organ fats and oils hang down from the front upper grate at this location, which is the ash pool of the conventional furnace. The matter that has passed through the gap remains unburned together with the ash at the bottom and is discharged to the outside of the furnace, causing a problem that the infectious medical waste cannot be completely sterilized. Further, even if the amount of unburned residue is increased and then heated by the auxiliary burner, only the surface of the residue is heated, and it is particularly difficult to incinerate the liquids accumulated at the bottom after the residue layer is thickened. . According to claim 5, when metal and glass are intertwined with each other between the pusher and the ash outlet, there is a problem in that the static force from one direction only bites into the metal and the glass cannot be moved.

In order to melt the last-remaining metals in the residue melting furnace of claim 6 using heavy fuel oil A or LPG fuel, about 15
It is necessary to raise the melt temperature to 50 ° C. However, conventional refractories that can withstand high temperatures are vulnerable to thermal shock, and a temperature control program must gradually increase the temperature. Since the burner will continue to be burned for 10 to 20 hours at the shortest, the fuel cost will be very high. In addition, in the case of indirect heating such as in a crucible, the temperature of the melt inside is set to 1
It can only be raised to 200 ° C. In this case, if the flame is directly hit, a problem arises in which lightweight residue such as ash is scattered. Also, if ash, bottle, and metal are melted while being mixed, the ash first melts at 1200 ° C, but if the temperature is raised as it is and melted together with the metal, the viscosity of the mixed melt increases extremely, and There is a problem that it becomes difficult to wash away the water. In order to automatically put the ash residue into the melting furnace, it is necessary to detect whether the furnace is empty or full. The empty state is known because the temperature inside the furnace reached 1550 ° C at which the last carbon steel melted out. However, the full detection has a problem in that the apparent specific gravity of the residue is different in each case, such as when there is a lot of ash and when there is a lot of metal, and at the same time, there is a high temperature atmosphere and the detection is impossible.
In claim 7, it is ideal to incorporate the reburn chamber and the cyclone into the small incinerator at the same time, but there is a problem that the outlet and the inlet through which the exhaust gas flows cannot be connected horizontally. In addition, it is required that the dust settled on the bottom of each of the reburn chamber and the cyclone is not required to be manually scraped from the sanitary side each time.

[0007]

According to a second aspect of the present invention, the incinerator in the furnace stays on the initially fixed slanted rostrut or the like, but it drops to the lower portion as the operation and combustion of the incinerator feed pusher progress. Will be done. The pusher feed rate is determined from the grate burning rate, the furnace load rate, and the basic performance of the furnace, but the burning rate varies depending on the intruding air temperature, the water content, the calorific value of the combustion products, etc. Therefore, in order to automatically load the next incinerated material on the conveyor without visual inspection, the combustion progress status sensor in the furnace receives a confirmation signal that the furnace is ready to be charged, then opens the furnace door and detects the conveyor full condition. 1 to receive
It is necessary to move by batch. Explaining with reference to Figs. 1 and 7, by installing 1 set of microwave transmitting and 5 receiving devices as full-space sensors on both sides of a 6-tilt fixed rostrur, it becomes possible to detect the state of reduction of incinerator in the furnace and automatically insert it. And automatic control of combustion progress in the furnace was realized. FIG. 2 in claim 3
In terms of the impact from incineration falling from above, considering the cross-sectional shape that can withstand enough, at the same time, the middle part where the load bearing condition becomes strict, the adjoining and connecting parts have more mechanical strength. To improve. Corresponding to thermal shock, the amorphous refractory has low thermal expansion characteristics and stainless steel wire with a diameter of 0.2 m / mφ is mixed in to prevent generation of fine cracks on the surface. Also, by inserting multiple stainless steel reinforcements in the inner longitudinal direction of the grate and in the direction perpendicular to this, even in the event of a grate break, these reinforcements prevent the chips from falling out, and the discharge pusher at the rear contact, Unattended automatic operation is possible because troubles due to debris mixing into the melting device are eliminated.

The fourth and fifth aspects will be described with reference to FIGS. 1 and 10. A portion corresponding to afterburning of the furnace is a fluidized bed of sand that has been subjected to high temperature heat storage, and 8 unburned matter from the upper grate and liquefaction. Complete incineration of polymer incineration materials and liquids. The temperature is 800 ° C to 9 with a combination of 27 thermocouples and 48 auxiliary burners.
The control is set so that the temperature is set to 00 ° C. Although the bottom of the fluidized bed section 10a is horizontal with respect to the traveling direction of the 9a discharge pusher,
Most of the convective sand is always gathered in the center by sloping to the left and right in the direction of travel to give it a shape like a boat bottom. Injectable materials such as injection needles in the sand on the 9b ratchet comb blade 9a ash,
By applying vibration with the residue discharge pusher and moving it forward, the plow is collected from the sand in front of the floor. The 9a ash and residue discharge pusher are not buried in the sand because they are on the 9d pusher guide rail, and do not disturb the convection of the sand. Collecting generated clinker etc. up to the discharge port and interlocking 1
0b Open the discharge door and discharge to the conveyor outside the furnace. Most of the ash particles with a grain size of 0.5-1.0 m / mφ that does not come into contact with the comb are blown up onto the sand layer and discharged by the pusher, but the fine ash particles mixed in the sand are successively accumulated without being combed. 10a, overflow the sand from the fluidized bed,
A situation arises in which the sand must be replaced frequently. By attaching a dust suction pipe in the sand 10d to the 9a ash and residue discharge pusher, dust in the sand is sucked up to the cyclone with a negative pressure, and a trapping means that does not cause clogging like a mesh screen is realized. As a result, the incinerated matter is pre-crushed at the joint with the stalker-type furnace that performs pre-combustion, and the sanding work is carried out after the sand is once carried out of the furnace.
A highly efficient combustion furnace with a fluidized bed type afterburning unit that can separate sand and incombustibles in the furnace without the need to separate incombustibles with a return bucket conveyor has been realized.

The description of claim 6 with reference to FIGS.
2 When the ash residue hopper is full and needs to be melted, open the damper for the 35 preheating exhaust gas bypass flue,
Exhaust gas at about 900 ° C. is passed from the 18a reburn chamber to the 17 exhaust gas bypass (outlet), the melting furnace, and the 13 extraction feeder to the 17 exhaust gas bypass (inlet). The inside of the duct has a negative pressure due to the 43 injectors installed in the chimney. Although it is rejoined with the main exhaust gas flow here, since there is a 35 furnace front damper that works in conjunction with the 27 melting furnace temperature sensing thermocouple signal, it is possible to control the bypass exhaust gas flow passage rate using preheating along with the temperature rise programming. It will be possible. When the temperature of the melting furnace is raised to the peak of 700 to 800 ° C, the 35 inlet damper is closed and the 28 jet burner is operated to raise the temperature to 1550 ° C. Even at this starting point, the burner output calorie is controlled so that the preset temperature does not cause a sudden temperature rise. To supply the molten material to the 14 melting furnace main body, the 34 upper furnace lid is moved horizontally, the upper furnace is opened, and the preheated residue is charged. The structure of the furnace is a cylindrical crucible that is installed so that the flame can be emitted in the tangential direction of the inner wall of the furnace and has a flame velocity for destroying the air insulating layer formed at the tip, with a 28 jet burner of about 100 m / sec to generate a rotating flame in the furnace. Use furnace type. However, the crucible furnace uses indirect thermal spray to remove the melt inside
It can be raised only up to about 200 ° C, and even if a high quality refractory material is used, it only takes about 2 to 3 times. Therefore, as the furnace, a cylindrical crucible furnace type is used, and instead of the crucible in the center, an indeterminate refractory cylinder having a plurality of notch openings is installed in the lower part to form a 29 melting vessel. 31 The inner floor of the furnace is laid with a certain thickness of metal on the refractory. This top level is set flush with the bottom of the melt outlet.

Referring to FIG. 6 in claim 7, in order to simultaneously incorporate the 18a main reburn chamber and the 20a cyclone into the small incinerator, the exhaust gas from the furnace is introduced into the 18a main reburn chamber from the upper part to reduce the flow rate and settle dust. The exhaust gas discharged from the lower part of the above is put into a newly provided 18b sub-reburning chamber. The 18b sub-reburn chamber has an inlet at the lower part, which is the reverse of the 18a main reburn chamber.
a Connect to the outlet of the reburn chamber. Similarly, the outlet is attached to the top and connected to the cyclone inlet. The settling duct is a mechanism that discharges to a 13-drawer feeder using a 47-gate open / close lot or an airtight rotary valve. Explaining in FIGS. 1, 4 and 9 in claim 8, 55 corona discharge plus electrodes which are hexagonal in order to eliminate voids in the flue and 54 corona discharge minus electrodes in the center corresponding to each hexagon. 57, 58 from the support. Distance between positive and negative electrodes is 50m
/ M, 12 kv, 1 m / mA to start corona discharge. A stream of charged particles is created in the exhaust gas passing through by colliding with the ions and electrons generated by spraying water droplets on the electrodes. The positively charged oppositely charged particles were attached to the rear of the negative electrode.
6. The negatively charged particle absorbing blade electrically neutralizes so that only negative particles remain in the charged particle flow. For the reaction humidity, a 41 slaked lime hollow cylindrical block placed on a mounting table is set by always moistening the surface and applying a positive voltage with a 40 positive electrode current collector. By the Coulomb force, it was possible to capture negatively charged water droplets and dust particles and to react with slaked lime to fix the acid as a base. In claim 9, the heat-resistant binder is used to form a hollow cylindrical shape with V-shaped groove notches on the inner and outer circumferences, so that the contact area is four times as large as that of a cylindrical type or a square hole. In addition, the inclusion of a trace amount of electrolyte has realized a calcium hydroxide cylindrical block that can be energized by moistening.

Referring to FIG. 4 in claim 10, the 36 mount is constructed of a mount base and a reacted slaked lime saucer, and four 52 insulator legs support the mount base on the saucer. . The 41 platform on which this slaked lime hollow cylinder is placed is processed with a round bar material into a grating shape to facilitate the escape of the charged particle flow rising from the bottom, and at the same time, the base that has peeled off after the reaction is placed outside the platform. The structure is such that it will not fall and will easily fall into the lower tray. The 36 platform is sent to the 42 reaction chamber by the 21 platform automatic changer, and the installed state is that the entire platform is positively charged by riding on the 38 platform and 40 positive electrode current collector. There is. The pedestal floor and the saucer are electrically cut off by four insulator legs. The 52 insulator leg has a structure for preventing direct exposure to the flow of charged particles by a cover 49 for preventing attachment of charged water particles. The 51 nozzle is attached to each case for cleaning the charged water droplet particles attached by leaking into the 49 charged water droplet particle attachment prevention cover. To explain with reference to FIGS. 1 and 4 in claim 11, calcium chloride produced by the reaction of hydrogen chloride, which is a main harmful gas in exhaust gas, with calcium hydroxide is increased in weight by 50% as compared with the original calcium hydroxide. . After the reaction, the calcium chloride was dropped by its own weight and scraped off by the 51 spray on the top, and all was collected in the platform tray. By measuring this weight change with 22 load cells at all times, the end of the reaction can be detected, and at this point, a system for exchanging a new one was realized by activating the 21 automatic changer body.

[0012]

The operation of claim 2 will be described with reference to FIG.
Microwave 4.15GH _z does not need professional management technician as of isotope, are relatively inexpensive and harmless to the human body, and at the same time can be transmitted through the refractory wall, not affected by the scorching It has characteristics. For the above reasons, there is no danger even if an unspecified number of people approach the furnace. (5) A steel plate hood is attached to the receiving part. (4) Microwave from the transmitter is used as if it were a beam of light. As a sensor that continuously monitors the presence or absence of the incinerator, it is effective in operating the automatic incinerator charging device. Claim 3
With reference to FIG. 2, mixing the fine stainless wire into the amorphous refractory as described above effectively acts to prevent the generation of fine cracks. As described in detail in section B, a clearance of about 0.03 m / m is provided in advance between the stainless reinforcing material and the amorphous refractory, which are the main bars of the 8 amorphous grate. This absorbs the thermal expansion of stainless during heating by operating the furnace, and eliminates the internally generated stress that causes cracks in the amorphous refractory because the clearance becomes almost zero, and effectively acts to prevent the destruction of the grate. To make clearance, apply a flame retardant paint to the stainless steel reinforcement material to the desired design thickness, assemble a formwork on this, and pour in an irregular refractory material. The paint burns due to later sintering heating,
Clearance can be created between the reinforcing material and the irregular shaped refractory. or,
8 The adjacent connecting protrusions of the grate not only complement each other and increase the strength, but also minimize the incineration of the grate that is disentangled and pushed in the direction perpendicular to the grate from falling out of the grate gap without burning. , The incineration works effectively to move smoothly on the stalker. When claims 4 and 5 are described with reference to FIGS. 8 and 10, preheated air from a 9c air outlet is blown out in a direction perpendicular to the boat-shaped 10a fluidized bed section, so that the sand rises along the slope from the bottom to the upper layer. There is a horizontal flow back to the center. The boat-shaped 10a fluidized bed is partitioned left and right by the 9d pusher guide rail in the center like the spine except for the front part D, so the sand returning to the center once hits the 9d pusher guide rail, and along it It flows down. In this way, left and right independent convection in the direction of the ribs is generated. This convection of sand causes only small incombustibles such as injection needles to flow together, but for large incombustibles such as bottles and clinker, 9e Versculin floats on the surface without being buried in the sand. It works effectively to collect in. On the 9e bar screen, bottles, iron pieces, and clinker generated in the upper combustion part gathered in the center part due to the convection of sand were swallowed to the bottom part of the fluidized bed part at 10a, and the air outlet of 9c was blocked and caught in the outlet. 3 functions with 19 heat exchangers that prevent the occurrence of situations in which the function of the fluidized bed is impaired, such as blocking convection
The air heated to 00 ° C. and the 48 auxiliary burners work to retain these burned bottles and metals in the upper layer of sand. As a result, the liquid incineration dripping from the upper grate is burned on the sand before it reaches the sand, or the combustion progresses while slipping through the sand, etc. Effectively increases efficiency. The 9a ash / residue discharge pusher rides on the sand upper layer on the 9d pusher guide rail and advances and retreats at regular intervals, and collects large incombustibles and light ash on the 9e bar screen on the front D sand. Also, 9a ash, 9b ratchet comb blade installed under the residue discharge pusher, small non-combustible material such as an injection needle in sand is applied to the sand by the vibration from the 61 vibration generator to the front D part. Collect plows. At the time of returning, it is in a state of being lifted to the upper part of the sand around the support bottle due to the resistance of the sand and the plow does not work. Since the stroke is not continuous operation, at the next start, the 9b ratchet comb blade returns at a fixed position perpendicular to the traveling direction due to its own weight, sand flow, vibration, and the like. Since the 9C air blowout port is not arranged in the D part, the convection of sand does not occur and the large and small incombustibles collected by the previous stroke operation of the 9a ash and the residue pusher do not re-diffuse.

The 10b discharge door is opened and closed in conjunction with the 9a ash and residue discharge pusher by the lot of the 10c pusher interlocking doors. Large and small incombustibles are extruded to the out-of-furnace conveyor while being extruded one after another. The vibration applied at this time effectively acts to remove sand from large and small incombustibles. 9e
The bar screen is not attached to the side surface of the fluidized bed 10a, and only the central part is provided. Large incombustibles once taken in by the convection of sand from the gap to the bottom also ride on the convection and head for the upper layer along the slope, and again 9e It is possible to return to the bar screen. In addition, to the place where the air escapes to the upper part while competing with the pressure of the 9c air outlet pushing air that tries to push up the upper sand layer in the lower part of the fluidized bed part 10a and the pressure due to the own weight of the upper sand layer that presses the sand. Weak suction force from 20a cyclone is acting 10
d As the dust suction port in the sand moves forward, 61
The vibration effect of the vibration generator is also added and the antagonistic balance is lost. The forced air becomes as if it were degassed, and the sand and dust flow in a slightly floating state to the dust suction port in the sand for 10d. Since the suction pipe inlet is opened in a trumpet shape as shown in detail in FIG. 10 and E, the inlet velocity V ₂ is much slower than the suction pipe upper velocity V ₁ and the suction force is weak. As a result, sand that is 10 to 30 times heavier than dust is not sucked up into the pipe at the suction pipe inlet, and only dust is sucked at the V ₁ speed and sent to the 17 cyclone inlet. When the suction pipe inlet is sucked at a velocity V ₁ with a straight pipe, sand may be sucked due to a slight change in the furnace condition. As mentioned above, 10
d The trumpet shape of the dust suction pipe in sand effectively acts to separate sand and dust. Further, the dust separation by the dust suction pipe in the sand 10d is effective because the sand in the fluidized bed 10a does not overflow outside the furnace and the sand is constantly used in a new state. A small amount of sand adheres to the incombustible material and is melted together with 30 ash and residue in the 14 melting furnace, but is taken in by other melting materials and flows out of the furnace.

As will be described with reference to FIG. 3 in claim 6, a temperature rising programmed jet burner flame is provided in the space between the outer wall of the melting vessel 29 and the inner wall of the melting vessel 31 to prevent excessive thermal shock to the furnace. It is possible to rotate it along the tangential direction to the inner wall of the furnace, which is horizontal with the part
It wipes up ash and residual melt, and acts effectively to bring the furnace to high temperature while maintaining pressure balance without generating suction pressure force. Also, the flame is heated several times, 29 melting vessel and 31 metal bottom floor heating, and exhausted to the cyclone through the top lid hole. The ash residue in the melting vessel is heated by heat conduction from the 31 metal bottom floor, by-side injection from the side wall of the vessel, and by flame and side-injection from the top cover. Again 2
Although there is an opening at the bottom of the melting vessel 9, since the thickness of the vessel is set to be much larger than the skirt formed by the angle of repose of the molten material, it does not appear in the gap through which the flame passes outside the melting vessel 29. For the reasons described above, since the flame does not directly hit the 30 ash and the residue, it does not scatter and the temperature can be raised to the melting point. 31 As the temperature inside the furnace rises due to the heat conduction of the metal bottom floor, the ash first melts and flows out of the lower surface of the melting vessel on the surface of the metal floor, reaches the inner wall of the furnace, and exits the furnace through the melt outlet. Since the metal bed is not yet molten, it will not mix with the molten ash. Similarly, glasses also flow out of the furnace. 31 metal bottom floor outside the melting vessel due to temperature rise,
It begins to be melted by the burner flame and gradually melts the inner side by heat conduction, and finally the inner metal also melts and flows out of the furnace. The melting temperature of ash, glass and metal is 200-300.
There is a difference of ℃. Catch this temperature difference and set it to 27 thermocouple sensor
By linking with the 6b sludge sorting conveyor, sorting sorting can be performed. When the furnace is empty, the thermocouple in the furnace detects the situation and the furnace lid is moved horizontally, and the ash / residue hopper bottom 13 drawer feeder operates to insert new ash and residue. Since the apparent specific gravity of the residue is different each time, it cannot be detected by the weight check with the load cell. For full detection, a level meter using 4, 5 microwaves with the same specifications as the in-front detection sensor is used from the side of the melting furnace. 5 Microwaves that act as a fine beam of light by applying a metal hood with a minimum size of 20 m / mφ to the receiving section are effective in accurately sensing the upper part of the repose angle term formed by ash and residues. When the seventh aspect is described with reference to FIG. 6, the 18b sub-reburning chamber as well as the 18a main reburning chamber allows the exhaust gas velocity to more sufficiently combust with the holding oxygen and also serves as a flue with less pressure loss. As a result, the exhaust gas outlet can be placed in a position where it can be smoothly connected to the cyclone inlet, and the 18a main reburn chamber and 20 cyclones can be effectively put into a small incinerator at the same time. Further, the pressure loss generated here can be sufficiently covered by the suction force of the 43-educator at the rear side. Explaining with reference to FIG. 4 in claim 9, as the reaction progresses, the outer surface and the hollow surface are peeled off,
By dropping it on the lower tray, the cross-sectional area through which exhaust gas passes increases and the pressure loss is reduced. Also, the increase in connection surface area is 4
It works effectively for downsizing of 2 reaction chambers, 36 pedestals, 21 automatic supply and discharge device.

When claim 8 is described with reference to FIGS. 1, 4, and 9, when the corona discharge is started, the ions and electrons in the exhaust gas are accelerated by the strong electric field near the discharge electrode, so that sufficient kinetic energy is exerted in the exhaust gas. Collide with the molecules of and ionize them, and more ions and electrons are rapidly generated. The 51 atomizing nozzle blows fine particles of water droplets prepared by mixing air and water into the 60 corona discharge zone. Ion electrons and the like generated in the 60th discharge zone are diffused according to the difference in ion concentration while thermally moving in the gas, and due to this diffusion, they collide with water droplet fine particles and dust fine particles to give an electric charge. However, over time, these attract each other due to Coulomb force and electrically neutralize, so to avoid this, in order to avoid this, behind the negative electrode which is the 54 corona discharge electrode (direction in which the exhaust gas advances), the same number of six blades parallel to the electrode. Attach a reverse charged particle absorption blade with 56. By adsorbing positive ions and positive and negative charged particles by Coulomb force to this blade, a charged particle flow composed of negative ions, negatively charged water droplets particles, dust particles, uncharged water droplets particles, etc. is generated in the gas. . The water droplets that have been blown in spread like mist throughout the exhaust gas,
At the same time as being charged, water-soluble harmful gas such as hydrogen chloride, zinc acid gas, and nitrogen dioxide is instantly dissolved and diffused in the liquid, and becomes charged water enemy fine particles made of acidic aqueous solution. Since it becomes an acidic aqueous solution and the electrical resistance of the water droplets becomes small, the reverse ionization phenomenon in which ions are separated when charged is not caused. Also, because of the high temperature inside the flue, some of the water droplets become water vapor, but even below the water vapor saturation point, uncollided ions in the exhaust gas and charged dust particles act as water condensation nuclei and are reversible again. To 5
9 Charged water drops act as fine particles. By reducing the velocity of the exhaust gas with the charged particle flow flue, it effectively acts to take in unadsorbed hydrogen chloride, SO _x , NO _x , dust particles and the like into the charged water droplet fine particles. Although the 41 slaked lime hollow cylindrical block of the 42 reaction chamber itself is not a conductor, the surface is always warmed with a thin film of water by the water jet from the upper nozzle that also has a cleaning function. By applying a voltage to the mounting table due to the effect of forming a small amount of electrolyte membrane such as sodium chloride that has entered, it works as a dust collecting electrode (plus electrode) of the electrostatic precipitator and adsorbs negatively charged water droplets and dust particles by Coulomb force. To do. In addition, the surface of the slaked lime hollow cylindrical block becomes covered with unreacted acidic aqueous solution thin film due to the incorporation of charged water droplets that have been converted to acidic aqueous solution, and Coulomb force easily acts on the entire shoulder, trapping and adsorbing efficiency as a dust collecting electrode. As the temperature rises, the acidified aqueous solution penetrates even into the fine cracks of the slaked lime block, causing a reaction not only on the surface but also inside, making it possible to efficiently fix harmful gas as a base in a single hour.

To explain with reference to FIG. 4 in claim 10, the mounting table is electrically cut by four 52 insulators into the upper cylindrical slaked lime block mounting bed and the reacted base tray.
When electrically connected, many charged water droplet particles are adsorbed by the Coulomb force on the large surface area of the saucer, and the desired acid-based water droplet fine particles cannot be fixed with the base due to the reaction between 41 calcium hydroxide. Does not react and becomes harmful gas again and diffuses into the atmosphere from the chimney, reducing the collection efficiency. Enclosed with a 49-cylindrical cover designed to prevent acid charged water droplet particles from adhering to the surface of the supporting insulator in the exhaust gas flow, to prevent the charged water droplet particles from directly colliding with 52 insulators and for a certain period of time. The function of performing cleaning by injecting clean water droplets into the cylindrical gabber from the side holes with 51 nozzles each time effectively acts on the insulation of the insulator. Explaining in claim 11 with reference to FIGS. 1 and 4, most of harmful gas is hydrogen chloride. On the table, when the calcium hydroxide has finished reacting with the calcium chloride, the weight increases by exactly 50%. The 22 load cell effectively acts to capture the load change amount transmitted from the 38 rods, one of which is a pin support, as a parameter of reaction progress. There is also a combination of spring and limit switch instead of 22 load cell. In the section B to B of FIG. 4, the arm of the 21-table automatic changing device is raised by 39, and when the 36-cylinder is lifted by raising the descending cylinder, the 36-cable is 4
0 Positive electrode Separated from the current collector and turned off electrically. Conversely, the descent is electrically turned on. The use of such a simple operation as the switch function is effective in a place where the conditions are bad, as in the above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Claims 1 and 2 will be described with reference to FIG. One incineration product placed in the corrugated cardboard is placed at the marked position on the two loading conveyor. The remaining amount of burned material in the 25 combustion chambers is monitored and grasped by 4, 5 microwave sensor. Microwave 24.15GH _z is, can be transparent if several sheets of chamotte-based brick, also, is not affected by the high frequency of灼炎, because that can not be squeezed to spread angle of the wave is large beam-like, the apparatus It couldn't be used in situations like. However, as shown in Fig. 7, 4 and 5 receivers are installed on the left and right sides of the furnace, and 20m in front of
By attaching a steel plate hood with an opening of / mφ to the receiver and strengthening the directivity of the wave as if it were in the shape of a beam, it can be used, and automatic injection by monitoring the combustion situation has been realized. The automatic door of the 3rd furnace works in conjunction with the 2nd feeding conveyor, but when the system fails, it can be operated manually by sliding the rollers on the rails. The 6-slope fixed grate is made of ductile cast steel, and is divided into multiple pieces to make it easier for the incinerated material to slide down, and at the same time to make it easier for the combustion air to flow behind the incinerated material. 7 The incinerator pusher operates with a timer to send incinerators forward one by one with a loosening effect. Claim 8
As described above with reference to FIG. 2, the irregular-shaped refractory grate has a clearance for thermal expansion absorption between the refractory and the stainless steel auxiliary material, and also for the thick backbone main reinforcement in the longitudinal direction, The thin reinforcements at right angles act as hoop joints, increasing shear and at the same time holding the refractory in case of cracks without falling. It should be noted that the purpose of the present invention is to prevent the occurrence of cracks when fine cracks are mixed with a stainless wire having a length of 25 m / m and a diameter of 0.2 m / mφ to prevent the occurrence of cracks. Due to these effects, we have realized an irregular-shaped refractory grate that has thermal shock resistance and can withstand use at high temperatures. In addition, the installation of one step at a time creates the effect of loosening and dropping the incinerated materials that are pushed later one after another and smoothing the flow. The central communication part also plays a similar role to the above while playing a strong mutual storage role.

Regarding Claims 4 and 5, 10a in FIGS.
The 9b ratchet comb blade, which works to plow out small incombustibles in the sand of the fluidized bed, is attached to the 9a ash, residue discharge pusher front lower side, and when moving forward, the force of the sand to cut in works It becomes perpendicular to the direction of travel and pushes up small incombustibles to the D section inclination. On the contrary, when returning, the resistance of the sand causes the surface of the sand to float and does not work as a plow.
The 9e bar screen is fixedly attached to the 9d pusher guide rail at the tip and the tail while being buried in the upper layer of sand. The 10d sand dust suction pipe is attached to the tip of the 9a ash and residue discharge pusher, and is passed through the 9c air outlet side. The passage passing through the 9a pusher has an inclination to prevent sedimentation of dust. By connecting the piping to the inlets shown in FIGS. 6 and 17, the pressure of 43 ejectors can be maintained so that the pressure is constant. The dust passes through the dust box under the 20a cyclone, passes through the 46 dust discharge pipe, and is sent to the 13-drawer feeder. A rotary valve is used for a 47-gate open / close lot when fully automatic. Explaining the incineration conditions in the furnace with reference to FIG. 1, incomplete combustion prevention and temperature control are
When the thermocouple 27 at the exit of the 25 combustion chamber senses the upper limit of 900 ° C, the water spray nozzle 26 for temperature control operates,
Lower the temperature by spraying with water. Due to the temperature drop, the progress of gasification of the combustion products in the 25 combustion chambers is reduced, and the required oxygen amount is kept within the set capacity of the 24 insufflation blower, which prevents incomplete combustion due to lack of oxygen. For the 48 auxiliary combustion burners which are mainly operated, the thing of 10a fluidized bed is used. Most of the combustion is completed in this part, and most of the supplied combustion oxygen is not consumed and is used in the upper combustion zone. Moreover, the temperature in the furnace is 900 ° C to 8
Controlling the temperature to 00 ℃ is dioxin and NO _x
Suppress the occurrence of. A 43-injector keeps the flue inside the furnace at a negative pressure all the time, and uses a balanced ventilation system that balances with a 24 pusher fan.

When claim 6 is described with reference to FIGS. 3 and 6, the preheating using the exhaust gas of the 14 melting furnace is returned from the 17 exhaust gas bypass (outlet) to the 35 preheating exhaust gas bypass (inlet) where the damper is opened. In order to load 30 ash and residue into 14 melting furnaces, use the 34 melting furnace charging lid cylinder, open the furnace door, and operate 13 drawer feeder until the upper level full signal of 4,5 microwave receiver / transmitter is output. However, since the operation of the 13-drawer feeder can detect the upper limit signal, the tact operation is performed so as not to continuously drop the 30 ash and residue. As with the automatic furnace charging, this level sensor is also equipped with a steel plate hood at the 5 microwave receiving part, and the temperature programmed 28 jet burner flame made possible by increasing the directivity of the wave is melted 29 times. The space between the vessel and the inner wall of the melting furnace 14 is heated directly at the metal bottom floor 31 at the same time as the other floor is indirectly heated at the same time.
The 31 ash residue remaining in the drawer feeder is preheated and discharged to the cyclone 17 exhaust bypass (inlet). 31 The metal bottom bed is directly heated by the burner flame, 29 is heated in the melting vessel, 29 ash and residue, and the one reaching the melting point passes through 31 metal bottom bed and 32 melt overflows Outflow from the exit. On the way, the melt is rapidly cooled and pulverized by the injection from the 33 quenching nozzle, and is collected in the 16 sludge storage box by the 15 sludge transfer conveyor in FIG. Finally, the furnace temperature (1550 ° C or higher) in an empty state in which the metals flow out and only the original 31 metal bottom floor remains
7 thermocouple senses again, 30 ash, 1 operation of residue input
2 Repeat until the ash and residue reservoir hoppers are empty. Claim 7
The flow of the exhaust gas will be explained with reference to FIG. 6 from the 25th combustion chamber to the 18a main reburning chamber, then to the 53b corona discharge exhaust gas ionizer of FIGS. 1 and 4 via the 18b sub-reburning chamber and the 20a cyclone. The scattered dust in the reburn chamber is accumulated at the inlet of the return pipe into the settled dust in the 44 reburn chamber by gravity settling. This and the dust accumulated in the lower part of the cyclone dust box are melted by going to the 13 drawer feeder through the 45 dust seal gate and the 46 dust discharge pipe when the furnace is stopped. The 47-gate open / close lot can be automated with an air-sealed electric valve.

Explaining claim 8 with reference to FIG. 9, the exhaust gas from the 20 cyclone passes through the 60 corona discharge zone of the 53 corona discharge exhaust gas ionizer. The structure of the corona discharger is such that the electrodes can be arranged in the flue without gaps by combining a plurality of 55 regular hexagonal positive electrodes, and at the center of them, there are six blade-shaped flat plates facing each side of the hexagon. By providing a negative discharge electrode, it became possible to create a 60 discharge band that spreads all over the flue cross section. As a result, the exhaust gas passing through the flue will not leak 6
Incorporates charged particles generated through 0 corona discharge zone, 5
9 Toward the reaction chamber via the charged particle flow flue. Reference numerals 57 and 58 are support materials for the negative and positive electrodes. 51 Atomizing nozzle is used to make the diameter of water droplets to be 10-40 μm.
The first reason is that when the water-droplet fine particles exceed 10 μm, the number of charges μ due to the collision mechanism with ions rapidly increases, and the adsorption of Coulomb force on the post-contact 41 slaked lime hollow block increases. The second is 55 positive electrode in which the length of the regular hexagonal cylinder is minimized by making the moving speed of the charged fine particles drawn to the 55 positive electrode much slower than the exhaust gas speed moving along the flue at right angles to the 55 positive electrode. It is possible to avoid the adsorption of Coulomb force of the negatively charged particles generated by the method onto the 55 positive electrode. As a result, most of the generated charged particles can be taken in and used in the flow of charged particles in the exhaust gas. For particles actually charged in the corona discharge band,
Calculate the velocity from the negative pole to the positive electrode of the corona discharge. The particles have an average size of 25 μm. The exhaust gas velocity is set to 1 m / sec, and the acceleration applied to the water droplet particles by the 51 atomizing nozzle is represented by the synthetic velocity vector (V ') without considering the conditions in FIGS.
It is the upper part of C section. 55 Regular electrode hexagonal cylinder L dimension is V '
If the number of poles proportional to is sufficiently long, the charged particles act like dust collecting electrodes of the EP dust collector and are all adsorbed to the positive electrode. 53 The temperature of the exhaust gas when entering the corona discharge device is lowered to about 600 ° C. by the air from the cyclone outlet 20b air intake port in FIG.
However, the higher the temperature is, the better the generation condition is. The ionization by corona discharge has already promoted the ionization of gas significantly in the state where the thermal motion is already vigorous, and the generation of ions is reduced due to the temperature drop at 51 atomizing nozzle injection There is nothing. Dioxins are most likely to be generated at around 600 ° C and adhere to dust in exhaust gas. Temporary exhaust gas temperature of 600 ℃
The purpose is to attach dioxin, which could not be prevented from being generated in the above manner, to the dust and to the dust collected by the post-contact device. Further, the oxygen supplied from the 51 atomizing nozzle and the air intake of 20b is for the purpose of positively generating ozone in the corona discharge part and using it for NO _x removal. 4 Oxygen in forced air is already used for combustion and is reduced in exhaust gas. The role of ozone is to oxidize water-insoluble nitric oxide (NO) in NO _x to water-soluble nitrogen dioxide. 9 in incinerator and melting furnace exhaust gas
0 to 95% is NO, and the remaining 5 to 10% is NO ₂ . _{NO 3, N 2 O 4,} N 2 O 5 is little. NO + O ₃ → NO ₂ + O ₂ NO ₂ easily collides with charged water droplet fine particles in the 59 charged particle flow flue to become charged aqueous solution particles. This enters the reaction chamber, 41
It is adsorbed by the Coulomb force to the slaked lime hollow cylinder and reacts to react with 2Ca (OH) ₂ + 4NO ₂ → 2Ca (NO ₂ ) ₂ +2
It is fixed as H ₂ O + O ₂ base and falls onto the saucer of the 36 slaked lime hollow cylinder mount. Similarly, sulfurous acid gas becomes charged sulfuric acid water droplets and is fixed in the reaction chamber in the form of Ca (OH) ₂ + H ₂ SO ₄ → CaSO ₄ + 2H ₂ O gypsum. On the surface of the 41 slaked lime hollow cylinder that has been warmed with the slaked lime and the electrolytic solution before the reaction, there is temporarily H ₂ SO ₄ that has not reacted with the slaked lime. This and N ₂ O
₃ reacts. H ₂ SO ₄ + N ₂ O ₃ (NO + NO ₂ ) → 2NOHSO
It is fixed as ₄ + H ₂ O nitrosyl sulfate. Most of the harmful gas is hydrogen chloride, and Ca (OH) ₂ + 2HCl → CaCl ₂ + 2H ₂ O calcium chloride is base-fixed. The calcium chloride after the reaction is scraped off by its own weight and the upper 51 spray nozzles, and is collected in the receiving tray of 36 mounts. 50% of new replacement
As the weight increases, the 22 load cell senses the weight change through the 38 platform support. Even if the furnace is operating in Fig. 4, when the reaction completion signal is output from the 22 load cell, the 37 reaction chamber door opens, and 21 the claw of the automatic changer body moves in and out of the 50 reaction chamber, and 42 reactions up to the maximum stroke due to cylinder operation. Extend it indoors. At this point, there is nothing on the 40b transfer conveyor. Next, the pawls of the main body of the automatic replacement device 21 lift up the mounting table by the raising operation of the raising and lowering cylinder 39. As a result, the 36 mount is separated above the 38 mount receiver and the 40 plus electrode current collector, and the electrical connection becomes 0FF, and at the same time, the 22 load cell sensing becomes unloaded. By the contraction operation of the reaction chamber inlet / outlet cylinder 50, the ascent of 39, and the lowering of the descending cylinder, the 36 platform is placed on the 40b transfer conveyor, and the 21 automatic changer main body becomes free. 40a pre-reaction slaked lime storage conveyor, 40b transfer conveyor and 40
By simultaneously operating the c-reacted slaked lime storage conveyor in the direction of the arrow, the 36-placed table of the reacted slaked lime moves to the 40c-reacted slaked lime storage, and the 36-placed table 40b transfer conveyor on which the 41 slaked lime hollow circle before the reaction is placed Be called into. Next, the 36 platform is moved from the 40b transfer conveyor to the 42 reaction chamber by the raising operation of the 39 raising / lowering cylinder and the extending operation of the 50 reaction chamber loading / unloading cylinder. 39 Ascending / descending cylinder descending operation 41 slaked lime hollow cylinder,
The 36 platform is transferred to the 40 electrode collector and the 38 platform receiver, so that the electrical connection is turned on and at the same time, the 22 load cell senses it. The 50 reaction chamber inlet / outlet cylinder contracts, the 37 reaction chamber door closes, and the replacement operation is completed. 40
The square storage conveyors a and 40c can be set to an arbitrary length according to the number of storage stands to be set in advance. The 51 reaction chamber nozzles mounted on the top and sides serve three functions. The first is to hit the surface and the inner surface of the 41 slaked lime hollow cylinder with a pressurized water drop to forcibly scrape the already-reacted base onto the lower tray to constantly expose the unreacted surface and improve the reaction efficiency. . Secondly, the 41 slaked lime hollow cylinder and 36 mounting table are kept in a constantly warmed state, and a voltage is applied from the 40 positive electrode current collector to make the whole positive electrode except for the insulated saucer. 41 A small amount of sodium chloride contained in the slaked lime hollow cylindrical block becomes an electrolytic solution by wetting and covers the surface, and at the same time, the collision of charged acidic water droplet particles makes it easier to conduct electricity and enhances the function as an electrode. Adsorbs fine particles and enhances reaction efficiency. Third is 51
The wet film formed by the nozzle water droplets and the charged acidic water droplet particles adsorbed penetrates into the fine cracks generated in the 41 slaked lime hollow cylinder and causes not only the reaction on the surface but also on the inside, increasing the reaction efficiency. It will be a matter.

[0021]

According to the first aspect of the invention, the fully automatic incineration system using the sensor can be operated without the need for a specialized person, and the incineration progresses only by placing the incinerated matter in the cardboard at the marked load position on the input conveyor. , A nurse, a person in charge of cooking in the kitchen, etc. can easily operate. In addition, since it can remove harmful gases and dust, it has the effect of withstanding use in dense urban areas. In the second aspect, the function of constantly controlling the furnace with the microwave sensor and the thermocouple burns the incinerator in a stable manner in the furnace according to the programming condition, but this does not cause a loss unlike the human visual inspection. The operation effect of 100% capacity of the furnace at all times and the energy saving effect by eliminating the waste cooking of the auxiliary combustion burner are produced by switching on and off according to the change in calorific value of the incinerated material. According to claim 3, the place where this grate is used cannot be completely burned in the previous stage, and the incinerated substances such as the injection needle, the blood in the bottle, and the diaper, which are pushed by the in-furnace combustion product feeding pusher while being loosened, are difficult to burn. This is the main combustion unit that receives the highest temperature. The grate of the present invention makes it possible to use it at a high temperature for a long time, which is required by an auxiliary burner from above and below. Claims 4 and 5: The burning bed of the present invention, the non-combustible material such as the generated clinker, were dropped by the bar screen from the front grate gap by installing the fluidized bed part of the structure floating on the sand upper layer as the post combustion furnace. It has an effect of efficiently promoting complete combustion of unburned organ oils and fats, polymer resins softened and melted, and liquids such as blood. Further, the pusher having a function of giving vibration in the traveling direction has an effect that it can be easily crushed and discharged even if the residue is entangled with static load. By vibrating the comb blade that has entered the sand, the sand that is floating by the pushing air can more easily pass through between the comb blades, and the effect of separating the incombustibles with the plow is improved. Fine ash floating on the sand layer is removed by the ash residue pusher.
Also, fine ash in the sand is separated from the sand by two means at the same time as the dust suction pipe in the sand, so that these have exactly the same function as the sieve, and as in the conventional fluidized bed furnace, they are used outside the furnace as a conveyor. It became unnecessary to install a sieve, and a low cost fluidized bed was realized. In addition, the increase in combustion efficiency due to the installation of the fluidized bed part is the effect of completely sterilizing infectious medical waste before melting the ash residue without leaving unburned lumps that may leave high temperature resistant virus in the ash and residue. Give birth. In the ash residue melting furnace according to the present invention of claim 6, ash, bottles and metals can be melted at the same time without prior separation, and glass (900-1100) can be controlled by melting point temperature control by automatic operation. ℃),
Ash (1200 ℃), injection needle stainless steel (1400-1
450 ° C.), cutlery carbon steel (1500 to 1550 ° C.), and the like have the effect that they can be easily taken out as building material sludge, metal materials, and the like. Sludge of ash and residue by type is to reuse resources and to completely sterilize infectious medical waste. Claim 7
As for the explanation, there is an effect that the whole equipment can be made compact by incorporating the reburn chamber and the cyclone at the same time, and the sedimentation dust can be melted without human touch. The primary capture of dust by a cyclone also has the effect of reducing the load on the corona discharge at the rear.

As has already been described for claim 8, a smoke-washing water treatment device and a fine lime blowing device for hydrogen chloride, a back filter device for dust particles, an EP dust collector, and SO _x . Had to install a desulfurization device, and a NOx removal device for NO _x and a device for removal. Since the present invention makes it possible to converge these functions into a single device, it is possible to easily attach them to a small-sized furnace by realizing the cost reduction of the conventional large-scale furnace dedicated equipment. Born Similarly, an exhaust gas treatment device has been realized that can be easily applied at low cost even when scaled up to a medium-sized municipal solid waste incinerator. In addition, since the efficiency of trapping harmful gases is greatly increased, it is possible to use it in a vinyl chloride furnace without combining it with a water treatment device. Claim 9 In the present invention, since the V-shaped groove is provided on the inner and outer surfaces of the cylinder, the surface area per weight is large, and the reaction chamber volume of the automatic replacement device can be greatly reduced. Due to the inclusion of a trace amount of sodium chloride and the wetting effect, a slaked lime block, which originally does not conduct electricity, acts as if it were a conductor and has the function of an electrode, and it is a means to generate a base by the reaction between the same acid and alkali. However, unlike the conventional equipment, it also has the effect of eliminating the need for a tap filter, an EP dust collector, and a water treatment device. As already described in claim 10, by electrically connecting with the hydrated lime hollow cylindrical block that is above the effect of the wet electrolytic solution on the surface, the mounting table has the effect of making the entire hydrated lime hollow cylindrical block the brass electrode. is there. In addition, the lower tray, which is electrically insulated by the insulator, holds the reacted base without spilling it, so that the load cell can accurately detect the progress of the reaction. As already described in claim 11, due to the structure in which the progress of the reaction is always captured by the load cell, there is an effect that the reacted slaked lime can be replaced with a new one without cooling even during the operation of the furnace. This automatic automatic replacement function without the need for cooling has the effect of being combined with the above-mentioned functions and can be introduced into a furnace for exclusive use of vinyl chloride, which consumes a lot of slaked lime. As described above, the effects of the present invention can be applied not only to small-sized furnaces but also to medium-sized and large-sized incinerators such as municipal solid waste incinerators.
