Due to the heat transfer, the temperature is raised (about 500 to 600 ° C.) and the low temperature pyrolysis gasification process is started.

Meanwhile, an upper portion of the first combustion chamber 220 includes a waste drying chamber 221 which is dried by heat and combustion exhaust gas, and a pyrolysis gasification chamber 222 in which pyrolysis gasification is generated by combustion heat in the center and the first combustion chamber ( The air supply nozzle 224 and the direct combustion chamber 223 are formed at the bottom of the 220, respectively.

In addition, in the re-extractor 230 installed at the lower end of the first combustion chamber 220, a water cooling jacket is installed into the cylindrical shaft 231, the re-discharge outlet 232 is formed extending to the bottom.

At this time, the re-extractor 230 is an electric drive rotary drum type with a spring suspension is installed in the center of the shaft 231, a water jacket (Water Jacket), to prevent the warp phenomenon by the upper incineration material temperature, It is configured to control the depth of the outlet (12.7㎜ → 30㎜) to prevent the inlet of the outlet inlet to smoothly discharge the incineration by the metal foreign matter.

The pyrolysis gas generated in the first combustion unit 200 is an air injection unit 300 for complete combustion of the second combustion unit 400 through a duct installed on the side of the pyrolysis chamber (first combustion unit 200). The air injection unit 300 is configured to suppress the generation of contaminants and to completely burn the second combustion unit 400 having an inverted triangular shape.

Referring to the operation of the present invention made of such a configuration as follows.

In the present invention, the waste is introduced into the hopper, and the injected waste is pyrolyzed and incinerated in the first combustion chamber. The exhaust gas generated after incineration of the waste is moved to the second combustion chamber, and at this time, air is injected into the second combustion chamber. The exhaust gas is completely burned to a high temperature. After cooling the combustion gas generated from the waste through the waste heat boiler, waste heat is recovered, and the exhaust gas cooled in the filtration and purification unit is collected by filtration.

In more detail, first, the collected waste is put into a waste pit in an incinerator by a conveying vehicle, and the put waste is put into a waste hopper by a waste crane.

At this time, the waste is crushed to a size of 150 mm or less by a biaxial shear type crusher installed under the waste hopper, and then dropped to the pit through a portion connected to the waste pit, and the crushed waste is operated by the operation of the waste crane. It is put back into the waste hopper.

Subsequently, the waste put into the hopper is pre-compressed to a predetermined amount (400 to 500 kg) by hydraulic driving of the waste input portion attached to the lower portion of the waste hopper and connected to the first combustion portion, thereby adjusting the waste level of the first combustion portion. When the "Low Level" signal is detected in the central control room by the operation of the sensing gamma sensor, the upper gate of the first combustion section is opened, and the pre-compressed waste is loaded into the loading chamber by the input device. After the door is closed, combustion exhaust gas (O2 concentration of 5-8%) is injected into the loading chamber to prevent explosions due to stable combustion and air penetration.

Then, after the waste charged in the loading chamber is injected into the combustion exhaust gas, when the lower gate is opened, the waste falls to the first combustion unit, and the lower input door is closed.

Subsequently, the waste injected from the first combustion unit is stored in a predetermined amount (4/5 of the volume of the first combustion unit), and continuously descends without a separate driving unit according to the degree of combustion and the bottom ash discharged from the lower portion.

At this time, the lower part of the first combustion unit is formed with a slope of a double symmetrical inverted triangle structure, and a high pressure and low pressure dual air supply nozzle for supplying a mixed air of circulating combustion exhaust gas and external air is installed through a high pressure nozzle. The air is injected at 99mmH ₂ O pressure, and the air is injected at 1.2mmH ₂ O pressure through the low pressure nozzle to burn the unburned powder in the incineration ash by the direct combustion by the high pressure nozzle and the low pressure nozzle.

The portion in contact with the inclined bottom surface of the lower portion of the first combustion portion is a region where direct combustion is formed according to the supply of the mixed air of the circulating combustion exhaust gas and the external air by the double air supply nozzle. It is made continuously and the upper part is dried by injection of heat and circulating combustion exhaust gas generated during the pyrolysis reaction.

The incineration ashes of which the final combustion is completed in the first combustion unit are discharged to the re-exit by the rotation of a cylindrical shaft (rotary drum type), which is a re-discharge device installed at the bottom of the double symmetrical inverted triangle structure, and falls into a completely closed tank. The ash is discharged to an incinerator container via a conveyor for final discharge.

Here, the re-extractor is an electric driven rotary drum type with a spring suspension device installed in the center of the shaft to prevent water from bending due to the temperature of the upper incinerator, and to control the depth of the re-exit (12.7). ㎜ → 30㎜) to prevent clogging of the ash outlet inlet by the metal foreign matter can facilitate the discharge of incineration ash.

The pyrolysis gas generated in the first combustion unit is moved to the air injection unit for complete combustion of the second combustion unit through a duct installed on the side of the pyrolysis chamber (first combustion unit), and the combustion air supplied to the air injection unit is electricity. By suppressing the supply of oxygen by lowering the oxygen concentration by mixing the fresh air heated by the heater and the combustion flue gas circulated in the chimney, it is possible to suppress the generation of thermal NOx and complete combustion in the second combustion part of the inverted triangle type.

In addition, the second combustion unit is completely mixed with the combustion air supplied from the air injection unit the pyrolysis gas generated in the first combustion unit to form a complete combustion, the dust of the combustion gas falls to the dust installed at the end of the lower reverse triangle slope It is removed and the hot combustion gas is moved to the waste heat boiler.

The combustion gas completely burned in the second combustion unit is removed from the dust and moved to the waste heat boiler, and heat exchange of the combustion gas occurs in the waste heat boiler.

In addition, the high temperature combustion gas generated in the second combustion unit injects the combustion gas circulated through the combustion gas cooling mixer installed at the front end of the waste heat boiler to lower the inlet temperature of the waste heat boiler to 850 ° C., and the air transfer shot ball. The steam produced by heat exchange in a vertically connected boiler combined with a cleaning system is converted to steam (hot water) or electricity at the energy source, and the combustion gas is cooled to 170 ° C or below, which is a temperature for preventing dioxin reformation. .

The combustion gas cooled to 170 ° C. or lower through the waste heat boiler is passed through activated carbon / lime lime injection equipment, a dry reactor, a bag filter, and dust in the combustion gas, harmful acid gases (HCl, HF, SOx, etc.), Organic hazardous substances such as heavy metals (Hg) and dioxins are treated at concentrations well below the emission standard and discharged to stacks through a manned blower.

In addition, in the low temperature pyrolysis process of the first combustion unit, low molecular weight pyrolysis gas such as carbon monoxide (CO), hydrogen (H ₂ ), methane (CH ₄ ) gas, oil and solid carbon (Char) are generated. Due to the proper temperature of the pyrolysis gasification layer, the oil is also evaporated to form oil vapor, and the pyrolysis gas and oil vapor are moved to the second combustion section by a manned vent, and the remaining solid carbon is lowered to reach the combustion bed. .

In the combustion bed, solid carbon is completely combusted with air (mixed air of circulating combustion exhaust gas and external air) supplied from combustion air nozzles installed in the furnace wall and the lower part of the furnace and discharged to the outside of the incinerator by driving the incinerator discharger. Due to the discharge of waste, the level of the waste in the first combustion unit is lowered, and when the waste input request level (Low Level) is displayed on the central control room computer by the operation of the waste level detection gamma sensor, the waste of the preloaded waste is charged. Continuous incineration operation is possible by input by the department.

The primary injection air (mixed air of circulating combustion exhaust gas and external air) supplied to the first combustion unit supplies much less air than the theoretical air amount, but solid carbon (Char), which is a pyrolysis gasification product, is completely burned to reduce ignition loss. It is injected at the bottom of the combustion chamber so that only low ash is discharged, and the generated pyrolysis gas is not burned and moved to the second combustion section.

At this time, the moved pyrolysis gas is turbulent through the high-pressure air nozzle at the air injection unit installed in front of the second combustion unit and completely combusted in the second combustion unit, and the total required air supplied to the first and second combustion units is It is 1.3 ~ 1.5 times of theoretical air volume, which is much lower than the theoretical air volume of 1.8 ~ 2.5 of general incinerator, so it has less combustion gas emission, and the facilities after the waste heat boiler are also small, so construction cost and maintenance cost are less than that of general incinerator. By injecting the primary injection air by mixing the circulating combustion exhaust gas and the external air, it is possible to maintain proper pyrolysis and combustion efficiency in the furnace.

On the other hand, in the case of incineration operation stops the waste carried in the incineration plant compressed and packaged by temporarily storing the waste compression packaging that can be incinerated during incineration when restarting the incinerator may be further installed on one side of the waste input, the waste compression packaging The waste is put into the waste hopper by the waste crane, and the shredded waste is transported by the conveying conveyor to produce the bale compressed and PP bent in the waste compaction machine. Packed in polyethylene film and temporarily stored by bale conveyors and bale storage cranes.

Here, the stored bale is compressed and packed, so there is no risk of odor and leachate leakage, so there is no effect on the surrounding environment due to temporary storage, and temporary storage of the landfill is performed by temporarily storing it in the bail storage room in the incinerator. The bales produced are transported by forklift trucks to the waste pit, mixed with the wastes received after scraping by the waste crane, and finally processed in the pyrolysis incineration process.

As described above, in the present invention, the waste collected in each region is also brought into the incinerator during regular inspections of the incinerator, and after compression bending by the waste compression binder of the compression packaging system, the baler is packed with polyethylene film (PE film) in the packaging machine. Produced, and temporarily stored in the incinerator after restarting the bale (Bale) has a merit that can be pyrolysis incineration treatment after sealing in the waste pit.

While the invention has been shown and described with respect to specific embodiments thereof, it will be appreciated that the invention can be variously modified and varied without departing from the spirit or scope of the invention as provided by the following claims. do.

As described above, according to the present invention, first, by injecting the waste directly without shredding the compressed and packed bales, a stable pyrolysis gasification is achieved according to the homogenization of the waste, thereby increasing the combustion efficiency and increasing the incineration amount.

Second, by increasing the depth of the re-discharge outlet groove of the cultivator and attaching a water cooling jacket, the incineration amount is increased (incineration capacity: 25 tons / day → 50 tons / day) according to the expansion of the direct combustion zone, the pyrolysis gasification efficiency and the incineration ash discharge The ease of use has the effect of improving incinerator performance and ease of operation.

Third, even when incineration of low calorific content of high moisture content can be operated without the use of auxiliary fuel has the effect of reducing maintenance costs.

Fourth, it is possible to completely burn the waste, the amount of pollutants such as dioxin is small and the waste reduction rate is about 92-94% higher than other incinerators, so there is less residue to be landfilled to extend the life of the landfill.

Fifth, the structure of the second combustion section is improved in the form of an inverted triangle to improve the efficiency of dust removal, and to reduce the efficiency of the waste heat boiler section due to dust, thereby reducing the clogging caused by the dust in the waste heat boiler section. have.

Sixth, when the operation stops for incineration inspection and maintenance, waste can be brought in and waste can be incinerated when the incinerator is restarted after temporary storage after producing the bale in the compression / packaging equipment. There is an excellent effect to reduce environmental pollution (leaching water, odor generation, etc.).
