Description

Continuous process for carbonization of condensed-organic-wastes using heat source of petroleum gas and oil made from polymer-wastes, and the equipments for the same}

The present invention relates to a continuous carbonization method and equipment for concentrated organic wastes using petroleum-based decomposition products obtained from petroleum-based polymer wastes, and more particularly, after complete drying of concentrated organic wastes such as food wastes, sewage sludge, and animal waste. As a fuel source for the carbonization process by heating in an oxygen-free atmosphere, the continuous carbonization method of the concentrated organic waste using petroleum decomposition products as a fuel to enable the use of petroleum decomposition products obtained by pyrolysis and distillation of petroleum-based polymer wastes and It relates to a facility for implementing this.

In general, industrial development is accompanied by an increase in various factories. Contrary to the development of scientific procedures, it is becoming more difficult to deal with pollutants emitted from factories, and in particular, since modern industries are based on petroleum, The amount of hard-decomposable petroleum-based polymer waste is considerable, and appropriate treatment measures are urgently needed.

In addition, as industrialization concentrates on urban populations, emissions of various types of household waste and food waste are also increasing rapidly.As a result, the livestock waste is largely increased due to the increase of livestock raising to meet the rapidly increasing meat consumption as the standard of living improves. Is increasing.

However, incineration of various wastes as described above has a limitation in securing cost and processing space, and there is a problem of secondary pollution such as dioxin discharge during incineration. Long-term and fatal pollution of the soil and groundwater by leachate, as well as the landfill is not easy to secure.

Moreover, although livestock waste is treated with offshore dumping in large quantities, such dumping is also reduced or banned.

In addition, not only food waste, livestock waste, but also organic wastes containing moisture such as sewage sludge, which are inevitably generated during biological treatment of water and sewage and industrial wastewater, have unique odors and high viscosity. Because it contains harmful components such as microorganisms and heavy metals, their treatment and disposal are very difficult.

As described above, the concentrated organic waste, which is difficult to process, has been mainly reliant on landfilling, but after drying, it is used as compost or after drying and incineration.

Carbonization of concentrated organic waste is a method of completely drying the concentrated organic waste and then heating it under an oxygen-free atmosphere to convert it into a carbide.The produced carbide is a solid fuel aid, a soil agent, a soil improving agent, a building material, an adsorption deodorant, a dehydration aid, and activated carbon. Since it can be used as a raw material, it is attracting attention as a very useful method for treating concentrated organic waste.

However, carbonization technology as a treatment technology for concentrated organic wastes such as food waste, sewage sludge, and livestock powder has been developed technologically since the mid-90s as drying and carbonization has become an environmental issue. , Bacteria, etc. are not effectively removed.

In addition, since it is difficult to process the process as an efficient continuous process by connecting several facilities, it is not possible to meet the operating costs even in the installed processing facilities because it cannot meet the fuel costs that have soared in recent years due to the dependence on batch processing. It is shrinking.

In addition, Korean Patent No. 306368, "Liquid and solid waste pyrolysis apparatus," Patent No. 445534, "Method for producing waste into powdered fuel", Patent No. 514663, "Compound waste incineration and drying. Each of the three inventions relates to an apparatus or method capable of comprehensively treating hardly degradable polymer waste such as waste plastic, waste oil, livestock waste, food waste, sewage sludge and the like.

However, the above three inventions are apparatuses for treating any one of polymer wastes or concentrated organic wastes or mixed wastes, and in the case of treating bulk solid wastes of 5-10 tons or more per day, the size of pyrolysis furnace is increased while transferring heat. The efficiency drops and the fuel cost rises excessively.

In addition, when treating concentrated organic waste, it is difficult to prevent or reduce the odor generated from the waste, and also consumes a large amount of fuel, so it is difficult to operate a large-capacity facility due to the high operating cost in recent years.

The present invention has been made to solve the problems of the conventional methods and apparatuses for decomposing petroleum based polymer wastes or carbonizing concentrated organic wastes, and to prevent odor spreading inevitably from concentrated organic wastes. By extracting fuel from petroleum-based polymer waste and using it as a fuel required for carbonization of its own fuel and concentrated organic waste, petroleum-based decomposition products obtained from petroleum-based polymer waste can be minimized. It is an object of the present invention to provide a continuous carbonization method of concentrated organic waste that can be used as and a facility for implementing the same.

In addition, the fuel obtained by decomposing petroleum-based polymer wastes is supplied to the concentrated organic waste treatment process, while the two types of wastes are separated and carbonized treatment of the concentrated organic wastes is carried out in a continuous manner instead of a batch type. It is another object of the present invention to efficiently circulate a large amount of concentrated organic waste by forcibly circulating the atmosphere inside the treatment to improve the heat transfer rate by tropical flow.

The object of the present invention is to encapsulate the conveying apparatus in the waste conveying section, to continue the decomposition process, to expand the thermal contact area of the object to be treated by the convection of the hot air in the furnace for large-volume treatment, multi-stage drying and carbonization of concentrated organic waste, It is achieved by fueling petroleum based polymer waste.

The continuous carbonization method and equipment of the concentrated organic waste of the present invention minimize the spread of odor according to the waste treatment, and the petroleum decomposition products obtained by the continuous decomposition process of polymer wastes in each processing step of petroleum-based polymer waste and concentrated organic waste. As it is used as fuel, it can not only maximize energy efficiency, but also force forced convection of heated air inside the furnace, which improves the thermal contact area and heat transfer rate to the treated waste, which significantly improves the efficiency of waste treatment and enables mass treatment. There is an advantage.

The present invention is to decompose petroleum-based polymer wastes to obtain petroleum-based decomposition products, that is, fossil fuels, and the petroleum decomposition products as fossil fuels as a fuel source required to carbonize concentrated organic wastes such as food waste, sewage sludge, and livestock. The present invention relates to a continuous carbonization method and an installation of concentrated organic waste.

Carbide continuous treatment of the concentrated organic waste of the present invention is largely composed of a petroleum-based polymer waste treatment step and a concentrated organic waste treatment step, looking at each as follows.

Petroleum based polymer waste treatment process, as shown in Figure 1, the step of crushing and stirring the waste (100); Filtering the foreign matter such as magnetic material from the pulverized and stirred waste (110); Drying the selected waste (120); Pyrolysing the dried waste (130); A step 140 of obtaining a fossil fuel by distilling the cracked gas generated in the pyrolysis step 130; Storing the fossil fuel (150); Consists of a sequential process such as

At this time, in the step (110) of filtering foreign matter, the magnetic material mixed with the petroleum-based polymer wastes is selected using a magnetic separator, and when the pulverized and selected petroleum-based polymer wastes are processed, the pulverization stirring step (110) and the screening. Step 120 may be omitted.

Drying the sorted waste 120 is in the range of 100 ~ 250 ℃, if the drying temperature is less than 100 ℃ drying time decreases the drying efficiency, and if it exceeds 250 ℃ petroleum-based polymer waste The risk of safety accidents increases with ignition.

The pyrolysis step 130 is a process of heating a petroleum-based polymer compound, which is a waste containing high caloric content such as waste vinyl and plastic waste, in an oxygen-free atmosphere at a range of 250 to 450 ° C., and the polymer compound is decomposed and gasified by heating. If the heating temperature is less than 250 ℃, the decomposition efficiency is lowered, if it exceeds 450 ℃ energy efficiency is reduced.

The pyrolysis step 130 is performed under an oxygen-free atmosphere, in which the heating atmosphere and the pyrolysis atmosphere are separated from each other. In this step, the waste heat generated in the heating atmosphere and the decomposition gas generated in the pyrolysis atmosphere are separated and discharged from each other. Is reused as a heat source such as drying step 120.

Obtaining the fossil fuel 140 is a step of obtaining the fossil fuel by distilling the decomposition gas obtained in the pyrolysis step 130, a part of the decomposition gas generated in the pyrolysis step 130 is a process of self or concentrated organic waste treatment process As it can be used as fuel, the remaining cracked gas that is not directly used as fuel is converted to fossil fuel through distillation and then used or sold as fuel after the storage step 150.

The concentrated organic waste carbonization process using cracked gas or liquefied fossil fuel obtained through the above process, as shown in Figure 1, the step of grinding and stirring the concentrated organic waste (210); Low temperature drying of the pulverized and stirred waste (220); Hot drying the low temperature dried waste (230); Carbonizing the high temperature dried waste (240); It consists of a sequential process such as the step 250 of cooling and transporting the carbide,

At this time, when processing the concentrated and agitated organic waste, the grinding stirring step 210 may be omitted.

The low temperature drying step 220 is a process of removing the remaining water (free water and surface water) remaining between the concentrated organic waste layer introduced, and is dried while directly contacting the air heated in the range of 100 ~ 250 ℃ and waste, If the drying temperature is less than 100 ℃, the drying time is long, the productivity is reduced, and if it exceeds 250 ℃, the fuel consumption increases more than necessary.

The high temperature drying step 230 is a process of removing organic water (bound industrial water and bound water) remaining between the molecules and the organic waste of the concentrated organic waste, dried under an oxygen-free atmosphere heated to 400 ~ 600 ℃, drying temperature If less than 400 ℃ organic moisture is not removed smoothly, if it exceeds 600 ℃ fuel consumption will increase more than necessary like the low temperature drying step.

In other words, waste water starts to dry efficiently at around 100 ℃, and organic water begins to be removed by breaking down molecules as it exceeds about 400 ℃. For complete drying, it is efficient to carry out in two steps as described above. .

The carbonization step 240 is a step of carbonizing the concentrated organic waste from which water is completely removed, and heating the waste in the range of 500 to 700 ° C. under an oxygen-free atmosphere that blocks external air. Due to the slow carbonization of organic waste, the practicality of the device becomes longer or the carbonization efficiency is lowered. If it exceeds 700 ° C, the fuel efficiency drops and there is a risk of safety accident due to overheating, and the cost of equipment increases.

At this time, as the heat source of the high temperature drying step 230 and the carbonization step 240, the decomposition gas generated in the pyrolysis step 130 of the petroleum-based polymer waste decomposition process, that is, non-condensed gas through the dry gas or distillation step 140 , Petrol, diesel, heavy oil is used, and the waste heat discharged from the high temperature drying step 230 and the carbonization step 240 may be used again in the low temperature drying step 220 as waste heat.

In addition, the waste heat discharged from the pyrolysis process 130 and the carbonization process 240 of the concentrated organic waste treatment process may be used in the drying step 120 and the low temperature drying process 220, respectively, After being collected, the drying step 120 and the low temperature drying process 220 may be used integrally. In this case, it is preferable to provide a waste heat distributor so as to appropriately control the amount of waste heat supplied to each process.

The preferred movement sequence of the waste heat as described above, in terms of temperature and safety, the pyrolysis step 130 and the carbonization step 240 → high temperature drying step 230 → low temperature drying step 220 → drying step 120 Order.

However, when the petroleum-based polymer waste treatment process and the concentrated organic waste treatment process are operated respectively, in the case of the petroleum-based polymer waste treatment process, waste heat flows in the order of pyrolysis step 130 → drying step 120, and concentrates. In the case of the organic waste treatment process, the waste heat distributor is automatically controlled by using PLC (PLC) so that the waste heat flows in the order of carbonization step 240 → high temperature drying step 230 → low temperature drying step 220. It is preferable.

Waste heat may also be used in the distillation step.

In addition, the exhaust gas generated in the low and high temperature drying steps 220 and 230 in the concentrated organic waste treatment process contains water, and the exhaust gas generated in the low and high temperature drying steps 220 and 230 is a water condensing device. And it may be introduced into the combustion device of the carbonization step 240 in the state where water is removed by passing through the water separator, such that the exhaust gas is removed in the carbonization step 240 is burned by the burner of the carbonization device Thus, the volatile odor component contained in the exhaust gas can be removed.

In addition, since the carbide obtained in the carbonization apparatus of the present invention is used as a contact agent for adsorbing heavy metals, odor molecules, etc. contained in the waste of the concentrated organic waste storage device, the carbide obtained in the carbonization apparatus may be used as it is, but vermiculite and / Alternatively, it may be used after the specific surface area maximizing treatment with elvan.

By the way, the specific surface area maximizing treatment, the first step of grinding the contact agent such as carbide in the range of 100 to 200 mesh; Firing the primary milled contact agent in the range of 800 to 1200 ° C; Secondary grinding of the calcined contact into 200 mesh or more; Acid treatment and alkali treatment of the secondary milled contact agent to elute metal oxides such as Al ₂ O ₃ and Fe ₂ O ₃ ; Drying the contact agent eluted with the metal oxide; And the like, by maximizing the specific surface area of the contact particles through the above process, the adsorption power for heavy metals, harmful substances, etc. contained in the waste is also maximized.

At this time, the acid treatment and alkali treatment for eluting the metal oxide is a process of depositing the contact powder in a solution such as hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide for a predetermined time and then drying.

The main component of vermiculite or elvan is SiO ₂ , and there are some Al ₂ O ₃ , Fe ₂ O ₃ , Na ₂ O ₃ and K ₂ O, among which Al ₂ O ₃ , Fe ₂ O ₃ , Na ₂ When metal oxides such as O ₃ and K ₂ O are dissolved in an acid, other heavy metal ions may be combined to form insoluble complex compounds at positions where Al ³⁺ , Fe ³⁺ , K ⁺ or Na ⁺ is attached. As acid treatment or alkali treatment. Only at least one of the two processes may be performed.

In addition, since the calcining treatment is carried out in the range of 800 to 1200 ° C as a pre-process of the acid treatment, other impurities contained in vermiculite, elvan, etc. are removed, and the specific surface area is increased to increase the heavy metal adsorption rate.

The screw 21B is mounted, and the cutting knife K is coupled to the outer circumferential portion of the transfer screw 21B which is close to the inner surface of the housing and the inner surface of the housing when rotated.

Therefore, the large waste among the wastes introduced into the inlet I is cut and crushed by the cutting knife K coupled to the inner surface of the housing 21A and the outer circumference of the transfer screw 21B, and the crushed waste is transferred to the transfer screw 21B. Agitated and mixed while transferring to).

At this time, it is also preferable to combine a plurality of stirring members (S) protruding in the axial direction on the front surface of the screw blades in the direction of the movement of the waste so that the waste conveyed by the transfer screw 21B can be efficiently mixed and stirred in the transfer process. .

The foreign matter sorting device 22 is a conventional magnetic sorting device used as a device for separating magnetic materials such as iron pieces mixed in polymer waste.

Drying apparatus 23 is a furnace for removing the moisture of the waste, as shown in Figure 4, the drying furnace is provided with the inlet (I) and outlet (E) on both sides for the continuous drying operation The transfer screw 23B is provided inside the 23A.

As a heating method of the drying apparatus 23, a convection fan (not shown) may be installed inside the drying furnace 23A and a burner (not shown) may be used to directly heat the inside of the drying furnace. In order to prevent the waste from burning in direct contact with the flame or heat source during drying, it may be heated by blowing hot air into the drying furnace.

In the case of blowing hot air into the drying furnace, waste pipe being transported through the hot air spray hole (H) is used as a rotating shaft (X) of the transfer screw (23B), and a plurality of hot air spray holes (H) are formed through the outer peripheral surface. It is also desirable to inject hot air directly into the air to maximize the contact area between the hot air and the waste.

The pyrolysis device 24 is a device for heating and decomposing dried wastes under an oxygen-free atmosphere. The pyrolysis chamber 24 is provided with an inlet I and an outlet E on both sides, and a pyrolysis chamber 24A having a transfer screw 24C. , And surrounds the outer circumferential surface of the pyrolysis chamber 24A and consists of a heating chamber 24B equipped with a burner B.

In each of the inlet port I and the outlet port E of the pyrolysis chamber 24A, a blocking member V (V ′) operated by a cylinder or the like for repeatedly blocking the inlet port I and the outlet port E is provided. Coupled to the lower end, the vacuum pump (P) for releasing the air remaining in the space between the upper and lower blocking member (V) (V ') inlet (I) between the upper and lower blocking member (V) (V') ) And the outlet (E), respectively.

That is, when a certain amount of petroleum-based polymer waste discharged from the drying apparatus 23 is introduced into the inlet I of the pyrolysis chamber 24A, the blocking member V at the upper end is opened while the blocking member V 'at the lower end is closed. And the air is closed, and the air is discharged between the upper and lower blocking members V and V 'as a vacuum pump P while the waste is located between the upper and lower blocking members V and V'. Opening the blocking member (V ') is to drop the waste to the transfer screw (24C) side.

And when the predetermined amount of waste falls to the discharge opening E by the conveying screw 24C , the upper blocking member V is opened in the state which the lower blocking member V 'is not opened, and a waste blocking member (the upper and lower blocking member ( After moving between V) and V ', the remaining waste which is not pyrolyzed can be discharged by opening the lower blocking member V' while the upper blocking member V is closed.

At this time, the upper and lower blocking members (V ') as the vacuum pump (P') before discharging the residual waste and opening the upper blocking member (V) for discharging the remaining waste while the lower blocking member (V ') is closed. The oxygen-free atmosphere must be removed to maintain an oxygen free atmosphere.

In addition, in order to improve the thermal efficiency of the pyrolysis chamber 24A, a suction pipe p is installed in the upper portion of the pyrolysis chamber 24A, and the pyrolysis chamber 24A and the heating chamber 24B are connected to one side of the suction pipe p. Passing sequentially through the back to the decomposition chamber 24A, it is also possible to install a return pipe (p ') having a circulation fan (not shown).

That is, as the circulation fan (not shown) sucks the decomposition gas in the pyrolysis chamber 24A through the suction pipe p, passes through the heating chamber 24B heated more hotly than the pyrolysis chamber 24A, and reheats it. In this state, thermal efficiency can be improved by re-injecting this into the pyrolysis chamber 24A.

At this time, as in the case of the drying furnace 23, using a tubular body through which the hot air jetting hole is formed as a rotating shaft of the transfer screw 24C , by connecting the return pipe (p ') to the rotating shaft is reheated through the hot air jetting hole Decomposition gas may also be injected.

The cracked gas generated by the pyrolysis device 24 configured as described above is partially used as fuel for the burner B of the heating chamber 24B while circulating the pyrolysis chamber and the outside, or the following distillation apparatus 25 is used. Waste heat which is converted into fossil fuel in the gas phase or liquid phase and discharged from the heating chamber 24B is used as a heat source of the drying furnace 23.

The distillation apparatus 25 is a conventional apparatus for distilling the cracked gas generated in the pyrolysis apparatus 24 using a catalyst to classify it into a plurality of oils in gaseous or liquid phase.

The fuel storage device 26 is a tank in which the fossil fuel obtained in the distillation apparatus 25 is separately stored according to the type. The fuel storage device 26 is installed to use the fossil fuel as the fuel. The device 26 is connected to the pyrolysis device 24 and the low and high temperature drying device and the carbonization device of the concentrated organic waste treatment section to be described below.

Concentrated organic waste treatment unit, as shown in Figure 2, the waste storage device 30; A grinding stirring device 31; A low temperature drying device 32; A high temperature drying device 33; A carbonization device 34; Carbide storage device 35; And the like.

The grinding stirring device 31, the low temperature drying device 32, the high temperature drying device 33, and the carbonization device 34 may be connected to a transfer device (not shown), such as a conveyor. Waste can also be fed directly to the side.

The structure and role of each of the concentrated organic waste treatment units configured as described above are as follows.

The waste storage device 30 is a tank for storing waste before processing, and the pulverizing stirrer 31 is a device for crushing and stirring the waste to a predetermined size or less, but the structure thereof is not limited. An apparatus having the same structure as that of the screw type pulverizing apparatus 21 of the system high molecular waste treatment unit is used.

Apparatus 34 has pyrolysis chambers 33A and 34A and pyrolysis chambers 33A and 34A, each having an inlet I and an outlet E on both sides, and having transfer screws 33C and 34C . The outer circumferential surface of the burner (B) is equipped with a heating chamber (33B, 34B) is mounted, the blocking member (V) (V ') and the vacuum pump (P) is provided, respectively.

In addition, the high temperature drying device 33 and the carbonization device 34 may be provided with a suction pipe p and a return pipe p '.

The carbide storage device 35 is a tank for storing the carbide generated in the carbonization device 34, and the carbide discharged from the carbonization device 34 is in a heated state, and thus the carbide storage device 35 may be cooled and stabilized while the carbide is transferred. Rather than allowing the carbide to be discharged directly from the carbonization device 34 to the carbide storage device 35, it is desirable to have an open transfer conveyor between the two so that the carbides are cooled in the process of being transported by the conveyor.

The equipment of the present invention configured as described above is for treating waste, and it is preferable to prevent the spread of odors generated during transport and disposal of waste, particularly concentrated organic waste, and an open conveyor as a transfer device connecting each device. Rather than using, it is better to apply a chain transfer device that is hermetically sealed and freely connected regardless of the position between the device and the device.

At this time, the driven sprocket (61C) can be replaced by a guide roller .

Waste introduced into the inlet (I) in the conveying apparatus as described above is transferred by the conveying plate coupled to the chain rotating in an endless track and discharged through the outlet (E), between the inlet (I) and the outlet (E) Since waste is transported through the sealed transport pipe inside of the container, odor is inevitably emitted only through the inlet and the outlet port, so that the spread of the odor into the transport space where the transport pipe is installed is prevented.

In addition, in order to use waste heat generated from the pyrolysis device 24 and the carbonization device 34 in the drying device 23 and the low temperature drying device 32, the pyrolysis device 24 and the carbonization device 34 are used in the waste heat distributor (Fig. It is also preferable to connect to one side of, and to connect the drying device 23 and the low temperature drying device 32 to the other side of the waste heat distributor.

In addition, in the case of the drying apparatus 23, the pyrolysis furnace 24, the low temperature drying apparatus 32, the high temperature drying apparatus 33 and the carbonization apparatus 34, the cross sectional area of the portion adjacent to the inlet I is Similar to the projection cross-section, but the cross-sectional area from the front of the portion adjacent to the inlet I to the outlet E is enlarged in order to minimize the loss of heat inside each device to the inlet side.
