Description

Sorting apparatus and method for recycling of inflammable wastes using surplus suction air and disk brush}

The present invention relates to an apparatus and method for separating flammable waste using surplus suction air and a disk brush. Specifically, in order to increase the separation efficiency of flammable waste contained in waste, the speed control gate controls the air velocity of the surplus intake air. An apparatus and method for separating flammable waste with clones and disc brushes.

Generally, most of the waste is disposed of by landfill or incineration.

In the early stages of reclamation, landfills were simply reclaimed without any environmental measures, which led to the spread of odors in the vicinity of the landfills, pests, algae, and rats, and groundwater and surface water pollution. In order to prevent such pollution gradually, the bottom of the landfill is equipped with an order layer or a membrane to prevent the leakage of leachate, and to prevent the spread of odor through daily soil and intermediate soil, or by forcibly extracting landfill gas by incineration. Action was taken to the extent that

In addition, the incineration method was simply incinerated near the landfill site in the early stages, and as a result, there was a tendency to incinerate cogeneration power plants that can gradually solve the air environment problem due to odors and pollution pollution of the air environment.

Furthermore, when landfilling waste, there is a problem of securing and reclaiming a large amount of land for processing a large amount of waste at once, and soil environment problems due to leachate before stabilization.

In the case of incineration, it is possible to treat waste in a relatively small site, but excessive facility costs as well as the disposal of incineration residues must be relied on for landfill, and there is a problem in the atmosphere due to incineration.

However, the biggest problem with the landfill or incineration method is that, above all, it is difficult to secure additional landfill sites or incinerator sites such as cogeneration plants because of complaints from residents near the landfill or incinerator. In light of this situation, there is an increasing need for pretreatment facilities that can reduce the amount of waste that is finally disposed of and recover recyclable resources from the waste.

Therefore, in order to solve such a problem, the amount of landfill or incineration must be reduced. Otherwise, the landfill or incinerator must classify the waste once again before the final landfill or incineration, but it is difficult to handle it mechanically. Only selective classification is made, and the rest can only be landfilled or incinerated, so efficient classification is not achieved.

Moreover, the waste contains a lot of flammable waste such as vinyl or plastic that can be used as a RDF (Refused Drived Fuel) and a lot of recycled materials such as steel, so that pretreatment before landfill or incineration It is necessary. RDF is higher in calories and cheaper than anthracite, making it a good resource for alternative fuels and heating for industrial and public institutions. As a result, local governments have recently attempted to use heating fuel using RDF, and the marketability is very bright.

Accordingly, there is a need for a method of classifying vinyl or plastic to be supplied to a waste fuelization facility, but there is a problem that a systematic classification facility is not yet provided.

On the other hand, conventional conveyors used as a means of transporting wastes in all waste sorting facilities that treat wastes including heatable wastes are transported at a constant speed (56-78 m / min), and waste is transported at this rate. The height of the waste transported in the conveyor is 50mm or more. In this case, combustible waste (styrofoam, vinyl, wood, etc.) is buried by the waste.

In particular, wastes having high water content or high content of flammable waste are more severe and have difficulty in separating flammable waste.

As a solution to this problem, there is a process using a method of separating flammable wastes with a rake to earth and sand conveying the conveyor as disclosed in FIG.

Referring to the conventional combustible waste separation process as shown, the first combustible waste separation process to separate the combustibles of 35mm or more while going through the waste input → conveyor → primary trommel → calqui → flammable separation step,

In order to re-select waste below 30mm discharged to the bottom of the first trommel screening process of the first combustible waste separation process, the second trommel → earth and sand separation step is performed again by second trommel and then sorted by size Second flammable waste separation process to separate flammables of less than 35mm again with a rake suitable for the size of waste discharged to each conveyor;

In the first combustible waste separation process has a third combustible waste separation process of sorting the combustibles by screening again the incombustibles selected by the rake again.

In the related art, non-combustible wastes (aggregates, soils, etc.) are separated by combustible wastes such as flammable wastes, thereby increasing the treatment cost by increasing the weight of the combustible wastes, and making the RDF difficult due to the low purity and calorific value of the combustible wastes. In addition, there is a problem in that high cost, complicated treatment wells, low energy efficiency, and difficult maintenance.

An object of the present invention for solving the above problems is to provide a device and method for sorting high-purity flammable waste by increasing the separation efficiency by using the excess suction air and a disk brush when screening the waste.

Another object of the present invention is to provide an apparatus and method for sorting waste by controlling the wind speed of the suction air according to the water content of the waste during separation by using the excess suction air and the disk brush.

In the wind speed control step, the discharge wind speed control is large according to the size of the screen of the sorting device, and if the waste discharged is large, the wind speed control gate is opened to introduce a lot of external air to increase the wind speed of the exhaust air, If there is little waste discharged due to the small size of the network, the wind speed control gate is opened with less external air, thereby reducing the wind speed of the discharged air.

When the wind speed of the intake air is weakened by the inflow of the outside air due to the opening of the wind speed control gate, the intake air inlet connected to the upper part of the high speed conveyor is configured to adjust the height of the inlet to increase the flammable waste suction power.

The present invention separates the combustible waste by inhalation air when sorting the combustible waste in the waste, so that the purity of the combustible waste is easy to produce RDF, and incurs little cost during incineration treatment;

In addition, by using the suction power of the blower to separate the combustibles to the wind to separate the combustibles of small size, the energy saving effect is large, and the process is simple,

In addition, the invention is a useful invention having the advantage of being able to select by controlling the wind speed of the intake air flowing into the blower according to the water content of the waste to be supplied at the time of separation and separation is an invention that is expected to be used in industry.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a plan view showing a waste sorting system according to the present invention, Figure 2 is a front view showing a waste sorting system according to the present invention, Figure 3 is a front view showing a flammable separation method using the suction air of the blower according to the present invention. 4 is a side view showing a method of separating combustibles using suction air of a blower according to the present invention, and FIG. 5 is a plan view illustrating a method of separating combustibles using suction air of a blower according to the present invention.

As shown, the present invention provides a first conveyor (3) by installing a blower (4) below the first conveyor (3) for discharging the waste passed through the vibrating screen (1) or trommel screen (2) as a sorting device. Blowing wind through the waste falling through the air is a light weight combustible waste is separated and discharged to the combustible waste storage (6) through the air conveyor (5) with the top and side is closed as a basic process equipment.

The present invention having such a device configuration falls to the bottom of the sorting device (vibrating screen or trommel screen) to separate the combustible waste contained in the waste that is sorted in the sorting device (vibrating screen or trommel screen) and dropped to the bottom. High speed to discharge the waste dropped to the bottom by sorting the air suction line (7) of the blower (4) used to separate the combustible waste from the waste transported to the first conveyor (3) without passing through When connected to the suction port 9 located above the conveyor 8 and driving the speed of the high speed conveyor 8 at high speed, the flammable waste is separated by the suction force of the blower 4, and a cyclone installed on the air suction line 7 is provided. Separated while rotating downward in (10), the air used for suction is sucked to one side of the blower (4) through the air suction line (7) through a passage formed in the upper portion of the cyclone (10) It is connected to a ward (not shown) and reused by wind power to separate the combustible waste contained in the waste transferred to the first conveyor (3).

At this time, if the rotary disk brush 11 is installed and driven in the inlet 9 for separating the combustible waste connected to the upper part of the high speed conveyor 8, the combustible waste buried in the waste is easily separated by the intake air, thereby improving the separation efficiency of the combustible waste. Raised.

The rotary disk brush 11 is installed only on the front end in the drawing according to one embodiment, but is preferably installed at the front end and the rear end of the suction port 9 to rotate the flammable waste while rotating the flammable waste buried in the waste. .

As described above, the present invention is a wind power for separating flammable waste of a small size (35 mm or less-35 mm or less as an example for better understanding of the present invention, which may vary in one embodiment). The use of the suction power of the blower (4) has a great meaning.

A blower used to separate and separate general wastes is used to separate combustible wastes of large size (35 mm or more-35 mm or more for clarity of the invention for better understanding of the invention. Blowing power is used. Since this blowing power uses only the exhaust air of the blower (4), the suction air of the blower was conventionally sucked in the atmosphere. However, in the present invention, by using the excess intake wind power not used as described above to separate the flammable waste.

In addition, by driving the high-speed conveyor (8) for transporting the waste with suction power at a high speed (and widening the width of the high-speed conveyor, the transport thickness of the waste is lowered to less than 10mm to reduce the phenomenon that the flammable waste is buried in the waste is easy to suction.

The high speed conveyor (8) is made to drive at a high speed by using an electric motor of a reduction ratio so that the moving waste moves to a low height, the speed of the general conveyor is about 60m / sec, but the present invention It was configured to drive the speed of the conveyor at least 180m / sec or more (three times the speed). This is because the flammable waste is well sucked by the intake air only when the speed is higher than this speed, thereby facilitating the separation.

In addition, the width of the conveyor is a general conveyor width of 900mm, but the present invention was to be 1500mm. This is because, at least in this size, the transport thickness of the waste, including flammable waste, is lowered to facilitate separation.

In addition, non-combustible wastes (soils, etc.) are small but heavy, so when the high-speed conveyor is moved, accelerations are applied to beat the wind power of the intake air, so that only flammable wastes are inhaled.

In addition, the present invention is to install the disk brush 11 in the front end of the inlet (9) to turn the waste upside down to facilitate the intake of flammable waste buried in the waste to double the separation efficiency of the flammable waste. The disk brush 11 is composed of a plurality of rotation to be coupled to one rotation shaft, the installation position is installed on the upper portion of the high-speed conveyor transported at high speed, the motor and the rotation shaft is directly condensed, or the gear connected to the motor or engine Or driving belt is coupled to the rotating shaft to drive. In addition, the shape of the disc brush is configured as a star shape having a plurality of blades as shown, the protrusion by stirring the waste to lift the flammable waste inside.

In addition, the present invention is to install the wind speed control gate 12 in the inlet portion of the blower (4) connected to the air intake line (7) for circulating air to adjust the discharge wind speed and the suction wind speed.

That is, according to the water content, the gate can be opened a lot when the dry waste is separated, and the gate can be opened a little when the wet waste is separated, thereby preventing the incorporation of fine dust such as earth and sand into the combustible waste, thereby effectively separating the combustible waste.

The form of the wind speed control gate 12 may be any configuration as long as it can adjust the area of the opening. For example, it may be a rotational method for adjusting the air hole of the old archer or a damper type for opening and closing the normal air duct.

However, it is configured to prevent the blower from being damaged by installing a net at the inlet of the blower to prevent the intake of the inlet from being blocked by flammable waste, etc., and to be configured to be open and closed to prevent damage to the blower. .

In addition, when the intake air is weakened due to the inflow of outside air due to the opening of the wind speed control gate, the height of the intake air inlet connected to the upper part of the high speed conveyor can be adjusted to increase the intake of flammable waste.

In the present invention, it is important to adjust the amount of air according to the water content of the waste or the size of the sorting network so that the suction and discharge is linked.

The waste separation method according to the present invention having the device configuration as described above will be described below.

The waste separation method of the present invention uses a wind suction air (surplus resources) used for the separation of combustible waste contained in the waste that has passed through the sorting device (thrommel screen or vibrating screen), Rommel screen) to separate the combustible waste contained in the sorted waste,

A first combustible waste separation step of separating the combustible waste of 35 mm or more from the non-combustible waste by the blowing force of the blower by the waste passing through the sorting device (vibrating screen or trommel screen);

The combustible waste is supplied by supplying the suction power of the blower used in the first combustible separation step through an air suction line while transporting and discharging the waste dropped by the sorting device (vibrating screen or trommel screen) to a high speed conveyor driven at high speed. At the same time, the suction efficiency is increased by damaging the waste on the high speed conveyor with a disk brush, and the sucked combustible waste is separated into combustible waste of 35mm or less from the cyclone installed on the suction line, and the air from which combustible waste is removed And a second combustible waste separation step to reuse the intake air of the blower used in the first combustible separation step through a suction line.

In addition, the present invention includes a wind speed control step of adjusting the discharge wind speed and the suction wind speed of the blower by installing a wind speed control gate in the suction port portion of the blower connected to the suction line.

At this time, the wind speed control step controls the gate to be opened a lot when the dry waste is separated according to the moisture content, and to open less when the waste is separated.

In addition, the wind speed control step increases the wind speed of the exhaust air by increasing the amount of outside air by opening the wind speed control gate if the waste discharged is large, and the large size of the waste is large according to the size of the sorting device in the separation phase of combustible waste. If there is little waste discharged due to the small size of the network, if the wind speed control gate is opened less, the inflow of outside air is less due to less inflow of outside air, and thus the air velocity of the exhaust and intake air can be controlled in the separation phase of flammable waste.

At this time, the inflow of outside air is increased by opening the wind speed control gate, so that when the wind speed of the intake air is weakened, it is configured to adjust the height of the intake air inlet connected to the upper part of the high speed conveyor to increase the intake of flammable waste.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
