Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a closed loop incineration system using dry / wet waste as a heat source,

The present invention relates to the field of incineration systems, and more particularly to a closed-loop incineration system in which dry or wet flame-retardant wastes can be completely burned under high-temperature combustion conditions, .

Industrial wastes such as waste oil, sludge, plastics, or various household garbage, dry waste such as synthetic resin or rubber is not decayed even if it is buried for a long time, so it is necessary to pollute soil and incinerate it. In the case of organic matter, toxic substances harmful to human body are generated. Therefore, in most developed countries, industrial wastes are strictly forbidden by landfill and incineration according to the law.

Therefore, the development of technologies for the treatment of industrial wastes has been promoted as a national project for decades, but the amount of industrial wastes such as synthetic resin and rubber has been gradually increasing due to the development of industry, There is no other way to get in.

In addition, waste oil, which is one of wet wastes, mainly occurs in the form of waste lubricating oil and waste oil in the fields of automobiles, ships, aircraft, machinery, edible oil, and animal (animal) .

Such waste oil is not collected, and if it is discarded or lost unauthorized, it will cause soil pollution, water pollution and marine pollution. Therefore, unauthorized disposal is prohibited in accordance with the Waste Management Act. Therefore, it takes extra time and cost to collect and process it, and various studies have been carried out to recycle it for a long time, and a typical application field is recycling as fuel. In other words, if waste oil is used as fuel for heating and the like, it is very economical because it can prevent environmental pollution and reduce fuel cost. However, since waste oil contains various kinds of normal impurities, Since it can not be burned and generates soot, it has a low combustion efficiency and its application field is very limited.

Conventionally, there have been developed various types of waste disposal apparatuses for treating industrial wastes and / or various household wastes as described above. After putting various wastes into an incinerator made of a refractory agent, heat is directly applied to the wastes, And waste generated during incineration is removed by a separate dust collecting device.

For example, a conventional incinerator includes an incineration tank, a magnetic body mounted on the bottom of the incineration tank, and an active oxygen supply member for supplying active oxygen to the incineration tank, as in the case of Registration No. 10-0638630, And a degassing tank installed adjacent to the discharge port of the incineration tank for liquefying the gas to be introduced therein. The gas combustion chamber is connected to the discharge port of the incineration tank and discharges the introduced gas to discharge the gas. And a gas purifying chamber communicating with the discharge port of the incineration tank for removing harmful components and odors of the gas introduced by using the platinum catalyst and discharging the harmful components and odors, An auxiliary fuel such as city gas is not required, and the gas discharged into the atmosphere is low temperature Value gasification incinerator has been made and the registration bar.

Also, as disclosed in Japanese Patent Application Laid-Open Publication No. 2011-0021704, the treated material is introduced from above, the bottom of the treated material is heated, the magnetized air having passed through the magnetic field of 2500 to 5000 gauss is led into the treated material, The magnetized air is naturally introduced into the lower portion of the processing apparatus in accordance with the natural exhaust from the exhaust pipe at the upper side of the one side of the processing apparatus, Decomposition part of the above-mentioned treated product is applied to the above-mentioned treated product to lower its weight in order to prevent its hollowing, and as a result of the decrease of the above-mentioned treated product, And the structure of the incinerator for burning the waste as in Patent No. 10-1223276 has been proposed The waste pyrotechnic gasification incineration system has been enacted and registered so that the amount of waste can be increased and the bridges and clinker phenomenon do not occur when the waste is burned.

However, such a direct-burning method (stoker method) in which waste is directly burnt by incineration is not sufficiently combusted due to various factors such as the amount and density of wastes, the size of the incinerator, the heating temperature and the content of water The pollutants such as soot, dust, and dioxin are generated, which has a disadvantage of seriously affecting environmental pollution.

In addition, since the dust collecting apparatus in the general waste disposal apparatus is not perfect for removing contaminants and harmful substances, it is inconvenient to frequently replace the filters and the like, as well as a lot of harmful substances are collected in the replaced filters There is a problem in that there is a problem in that it is necessary to treat them separately and there is a lot of structural problems such as incineration treatment cost due to use of excessive fuel in order to incinerate waste water containing water into an appropriate temperature.

Hereinafter, a closed-loop incineration system using the dry / wet waste as a heat source according to the present invention will be described in detail with reference to FIGS. 1 to 4 attached hereto.

A closed-loop incineration system (hereinafter referred to as "incineration system") using a dry / wet waste as a heat source according to the present invention is a waste incineration system that uses liquid wastes such as waste oil, waste lubricating oil, waste acid, waste alkaline, and waste sludge, , Solid waste such as waste tires, car scrap, etc., it is difficult to treat in a single process. Therefore, it is possible to burn in a single incineration system, It is characterized by one.

A closed-loop incineration system 10 using such dry / wet waste as a heat source is comprised of a dry waste supply unit 100, a crusher 200, a waste oil tank 300, a mixer 400, a combustor 500, 600, a boiler 700, a semi-dryer 800, and an semi-drying waste supply unit 900, and these components are connected in a closed circuit manner.

The dry waste supply unit 100 collects combustible and flame-resistant solid waste such as waste plastics, waste rubber, automobile scrap, and the like, and feeds the collected waste to the crusher 200. The dry waste supply unit 100 includes an inlet 111 and an outlet 112 arranged in a staggered arrangement The feed screw 120 may be formed of a screw housing 110 and a feed screw 120 installed in the longitudinal direction of the screw housing. In this case, It can be transported while being crushed or compressed so that a primary crushing effect can be obtained. Alternatively, the conveying means may be a plunger type which pushes the dry waste by hydraulic or pneumatic pressure.

The pulverizer 200 is an element for easily pulverizing the dry waste transferred from the dry waste supply unit 100 into the combustor and is provided with an inlet 211 at a position corresponding to the discharge port 112 of the dry waste supply unit A pulverizing cylinder 210 and a crushing blade 220 for pulverizing the dry waste put into the pulverizing cylinder into the pulverizing cylinder in a predetermined size.

The crusher 210 includes a crushing chamber 212 for crushing and a collecting chamber 214 for trapping crushed dry matter passing through the mesh plate and partitioned by a mesh plate 123 at a lower portion of the crushing chamber ).

The waste oil tank 300 temporarily stores liquid waste such as industrial waste oil and household waste oil. Since the waste oil tank 300 has a limited capacity, when the amount of stored oil oil becomes full, the waste oil is introduced And auxiliary oil tanks (not shown) may be installed to store auxiliary oil for overflowing in the waste oil tanks.

The mixer 400 is an element for agitating and merging the dry waste pulverized in the pulverizer and the waste oil pumped by the pump p in the waste oil tank 300 and is used for mixing the pulverized dry waste and the liquid waste, 410), and a stirring vane (420) which is rotatably installed in an agitating cylinder and mixes the waste in the agitating cylinder.

The combustor 500 is a key element of the present invention for burning mixed waste mixed in the mixer 400. The combustor 500 can completely burn mixed waste mixed with flammable and flammable wastes So that it has a combustion temperature of 1,000 ~ 2,400 ℃. The combustor 500 for this purpose includes a combustion unit 510, an ignition unit 520, a primary combustion chamber 530, a primary blower 540, a secondary combustion chamber 550, a secondary blower 560, Plate < RTI ID = 0.0 > 581 < / RTI >

Since the upper housing 512 has a corn shape in which the cross-sectional area decreases toward the upward direction, the combustion surface area is wider than that of the vertical shape, so that the air supply amount is increased and the combustion time is shortened, . On the other hand, since the lower housing 511 has a conical shape in which the cross-sectional area decreases as it goes downward, the combustion air can circulate smoothly without vortexing.

The waste compartment 513 may have a double wall structure, and the combustion gas flowing through the lower portion may be guided to the upper center portion via the double wall. That is, the waste implements 513 are composed of an upper open type internal gear 513a on which the mixed waste is placed and an external gear 513b disposed outside the internal gear so as to be spaced apart from the outer circumferential surface of the internal gear unit And an inlet port 513c through which the combustion gas flows is provided in the lower portion of the external teeth 513b.

Therefore, the combustion gas introduced through the inlet 513c is guided to the upper portion of the waste mover 513a through the passage 513d between the inner mover 513a and the outer mover 513b.

As a result, Thereby increasing the combustion temperature and enabling rapid combustion. It is preferable that the cross sectional area of the upper discharge port 513f of the bent portion 513e is smaller than the cross sectional area of the flow passage 513d because the combustion gas discharged to the upper discharge port 513f through the flow passage 513d is relatively The flow velocity of the combustion gas is increased when passing through the narrow top discharge port, thereby increasing the circulation speed of the combustion gas, and also serves as a nozzle for injecting the combustion air into the combustion core.

[

In addition, since the primary combustion air supplied downward while being rotated along the inner circumferential surface of the inner cylinder 531 of the primary combustion cylinder 530 is positioned close to the combustion nucleus, the temperature is further increased and supplied, have. In addition, since the combustion air passes through the air passage 533 between the double walls, heat is generated and the combustion heat in the primary combustion chamber 530 is not conducted to the outside. As a result, It may be made of a heat insulating material (e.g., plastic). This is advantageous in terms of manufacturing because it can broaden the selection range of the material, and the secondary communication pipe 550 having a double wall structure can also have the same effect.

The inner cylinder 531 of the primary combustion cylinder 530 is configured to be lower in height than the outer cylinder 532 and the air passage 533 is blocked at the upper end of the primary combustion cylinder 530, A shutoff valve 581 for shutting off the communication with the air passage is provided at a central portion of the shutoff valve 540. A discharge pipe 581a for discharging the exhaust gas burned in the primary combustion chamber 530 to the secondary combustion chamber 550 is provided at the center of the shutoff valve, May be provided. The lower surface of the blocking plate 581 may be provided with an induction plate 582 which is vertically spaced apart from the upper inner surface of the inner tube 531 by a predetermined angle.

Therefore, the combustion air supplied from the primary blower 540 installed at the lower side of the primary combustion cylinder 530 swirls and spirals through the air passage 533 between the inner cylinder 531 and the outer cylinder 532 (Flame) which is a pillar of the primary combustion cylinder 530 while being turned spirally along the inner wall surface of the inner cylinder 531 after reaching the blocking plate 581 of the primary combustion cylinder 530 The combustion unit 510 is lowered along the inner circumferential surface of the upper housing 512 to burn the mixed waste, and then the mixed waste is burned in the central portion of the primary combustion cylinder 530 The exhaust gas rises while spiraling.

In this process, the combustion air clogged by the blocking plate 581 and passed inward from the upper end of the inner cylinder 551 can be guided downward without spreading by the induction action on the induction plate 582.

The secondary combustion cylinder 550 has a double wall structure in which the inner cylinder 551 and the outer cylinder 552 are spaced apart from each other at a predetermined interval and is installed on the upper portion of the primary combustion cylinder 530. Exhaust gas is discharged to the upper plate 554 An exhaust port 554a may be provided. The inner cylinder 551 of the secondary combustion cylinder 550 is configured to be lower in height than the outer cylinder 552 so that the inner cylinder 551 and the outer cylinder 551 of the secondary blower 560, The secondary combustion air injected and raised into the air passage 553 between the inner cylinder 551 and the inner cylinder 552 can be swung downward beyond the upper end of the inner cylinder 551.

The lower surface of the upper plate 554 may be provided with an induction plate 583 spaced apart from the upper inner surface of the inner tube 551 by a predetermined distance and vertically formed. The guide plate 583 serves as a guide for guiding downwardly the secondary combustion air passing over the upper end of the inner cylinder 551 without spreading.

The inner cylinder 551 and the outer cylinder 552 of the secondary combustion cylinder 550 are preferably smaller in diameter than the inner cylinder 551 and the outer cylinder 552 of the primary combustion cylinder 530. This is because the pneumatic cylinder of the primary combustion cylinder 530 is transferred to the secondary combustion cylinder 550 and the force is weakened. Therefore, the combustion air passing through the air passage 553 of the secondary combustion cylinder 550 becomes the primary The temperature is lower than the combustion air of the communication 530. The diameter of the inner cylinder 551 and the outer cylinder 552 of the secondary combustion cylinder 550 is configured to be smaller than the diameter of the inner cylinder 551 and the outer cylinder 552 of the primary combustion cylinder 530, It is possible to prevent the problem of descending.

It is preferable that an atomizer 562 for spraying water to the air passage 553 of the secondary communication pipe 550 is installed in the blowing pipe 561 of the secondary blower 560. The water sprayed from the sprayer 562 flows together with the combustion air, and the temperature rises due to the combustion reaction by the combustion nucleus (pillar) which reaches the center of the secondary combustion cylinder 550, And OH, it is possible to completely burn unburned exhaust gas in the primary combustion chamber.

The collection water in the dust collecting box 620 may be discharged by discharging polluted collecting water and supplying new collecting water. Alternatively, the contaminated collecting water may be purified by a separate purification facility and reintroduced.

The boiler 700 is provided for supplying hot water by utilizing high temperature exhaust gas (waste heat) supplied to the submersible type dust collector 600 and includes a supply chamber 710 to which supply water for heat exchange is supplied, And a heat exchange pipe 720 installed in a currugate shape for improving heat exchange efficiency and through which exhaust gas passes. Accordingly, since the supply water supplied to the supply chamber 710 is heat-exchanged at a high temperature by the heat exchange pipe 720, it is possible to supply hot water utilizing waste heat.

The semi-dryer 800 is for semi-drying the wet waste by the high-temperature exhaust gas supplied from the boiler 700. The semi-dryer 800 of the present invention is an additional element utilized as a heat source for drying the wet waste without discharging the residual waste heat supplied from the boiler, unlike the conventional dryer, Residual waste heat is a heat source that is not enough to completely dry the wet drier because the temperature is lowered through heat exchange in the boiler, but it is used for semi-drying without releasing it because it has a suitable temperature for semi-automatic operation.

The semi-dryer 800 includes a drying cylinder 810 in which wet waste is stored, a waste heat inlet 811 through which the residual waste heat supplied from the boiler 700 flows, and a waste heat outlet 812 through which residual waste heat is discharged, A stirring vane 820 which is installed in the drying cylinder so as to be rotatable in the longitudinal direction of the drying cylinder and stirs the wet waste introduced into the drying cylinder.
