Description

Pretreatment apparatus of living wastes with reducing odor and method

The present invention relates to a method for pretreatment and apparatus for reducing household odors, and more particularly, to sort and recycle household wastes that are simply buried or incinerated, by classifying them by type while reducing the occurrence of odors at a low cost and simple process before landfilling or incineration. It relates to a pretreatment method and apparatus.

Generally, most of the household 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, the landfill floor is equipped with an order layer or a membrane to prevent the leakage of leachate, and to prevent the spread of odor through daily cover and intermediate cover, or to forcibly extract and incinerate the landfill gas as it progresses. Action was taken to the extent.

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.

However, when landfills are disposed of, there are problems such as securing and reclaiming large-scale land for processing large amounts of waste at once, and soil environment problems due to leachate before stabilization.

In the case of incineration, it is possible to treat domestic waste in a relatively small site, but excessive facility costs as well as disposal of incineration residues have to be relied on for landfill, and there are problems with the atmospheric environment due to incineration.

Above all, the biggest problem in the current landfill or incineration method is that it is difficult to secure additional landfill sites or incinerator sites such as cogeneration plants because of civil complaints from the landfill or incinerators. 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 landfills or incineration should be reduced, and most of these household wastes are classified at home, so if the household waste reduction efforts or the correct classification are not performed in each household, such a purpose can be achieved. Becomes difficult.

In the end, landfills or incinerators have to classify household waste once again before final landfill or incineration, but it is difficult to process mechanically, so only selective classification is made by hand, and the rest can only be landfilled or incinerated. It is not.

Moreover, such wastes contain a lot of vinyl or plastic that can be used as RDF (Refused Drived Fuel), and a lot of recycled materials such as steel, which require more pretreatment before landfill or incineration. It is true. 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 demand for a method of classifying vinyl or plastic to be supplied to a domestic waste fueling facility, but there is a problem that a systematic classification facility is not yet provided. The reason is that the garbage can be sorted and sorted out after the daily garbage bag. However, the garbage is inevitably generated, and the garbage must be recycled after every garbage bag.

Therefore, the necessity of a pretreatment process or a device for dividing household waste and sorting by a simple process while removing the odor generated at this time is increasing.

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 describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a perspective view showing the device configuration of the present invention, Figure 2 is a front view showing the device configuration of the present invention, Figure 3 is a rear view showing the device configuration of the present invention, Figure 4 is a device configuration of the present invention Fig. 5 is a left side view showing the device configuration of the present invention, Fig. 6 is a plan view showing the device configuration of the present invention, and Fig. 7 is a perspective view showing a part of the inside of the device configuration of the present invention.

As shown, the configuration of the present invention is a primary shredder (1) for breaking and shredding the garbage bags;

A disk screen (2) for sorting the debris by the set size;

Scattering combustibles separating means (3) which blows away household garbage of a set size (40 mm) or more passing through the disk screen and separates the scattered combustibles with reduced odor;

Fly-separating means (4) for discharging the fine combustibles scattered to the bottom of the set screen (40mm) and discharged to the bottom to reduce the odor while separating the scattered fine combustibles separating means (3) and;

Primary sorting conveyor (5) for re-selecting the iron and combustibles while transporting the non-scattered waste out of household waste of more than a set size (40mm) passed through the disk screen;

A secondary sorting conveyor 6 for separating the combustibles falling after being separated by the scattering combustibles separating means 3;

The secondary sorting conveyor (5) consists of a secondary shredder (7) for crushing the combustibles.

Although the setting size is illustrated as 40 mm above, the setting size may be changed as desired.

In the above, between the primary schrader (1) and the disk screen (2), the discharge screen (8) for transferring the waste discharged from the primary shredder and the waste dropped from the discharge conveyor, if necessary according to the site installation conditions (2) It further comprises a conveying conveyor (9) for dropping and supplying from the upper portion.

In the above, a magnetic separator (not shown) may be installed between the primary schrader 1 and the disk screen 2 to separate the steel materials.

In addition, the wastes discharged without being collected by the scattering fine combustibles separating means 4 among the wastes of the set size (40 mm) or less discharged to the lower portion of the disk screen are finally separated by the iron drum (not shown) before discharge. Can be configured.

In addition, by installing a magnetic separator (not shown) at one point of the primary or secondary sorting conveyor can be configured to separate the steel.

Among the wastes having a predetermined size (40 mm) or less discharged to the lower portion of the disk screen, the main components of the wastes which are not collected by the scattering fine combustibles separating means 4 are organic matter, and the wastes discharged to the primary sorting conveyor are non-combustibles. The main component of the waste that has passed through the secondary schrader is flammable, which is used for RDF production or cement kiln fuel or gasification raw materials.

Hereinafter, the configuration and operation of the present invention in more detail.

The primary shredder (1) and the secondary shredder (7) is a shredder may use a general shredder, but in the present invention to break the waste by the rotation to solve the high cost of frequent maintenance and replacement The shredding blade formed on the drum was used in such a way that it could be exchanged like a bucket tooth of heavy equipment such as an excavator. That is, the tooth frame is arranged and welded around the one or more drums driven by the schrader according to the arrangement of the desired shredding blades, and the cap, which is a shredding blade having a strong strength such as high speed forging steel, is fixed to the tooth frame fixed to the drum. Put on, the fixing pin from the side is used to drive through the groove formed between the cap and the tooth frame fixed.

The disk screen 2 is installed by using a disk screen that can adjust the installation angle using the first angle adjusting member 21 and the second angle adjusting member 22 located in the lower portion of the organic matter is high If you adjust it at a high angle (5 degrees-20 degrees), and if the ratio of organic matter is low, you can effectively adjust the sorting operation by the size of various kinds of household waste mixed with various kinds of low angle (5 degrees-0 degrees). However, the detailed operation description and configuration regarding the angle adjustment of the disc screen is not the core of the present invention, and the detailed description thereof is omitted since the detailed configuration may use any of the known angle adjustment functions.

The reason for limiting the angular value of the disk screen as described above is that when the ratio of the organic matter is less than 5 degrees, the organic matter is not sorted due to the insufficiency, but is discharged together with the combustible, thereby degrading the purity of the combustible. In addition, it is because the inclination is larger than 20 degrees to transfer the organic material, rather, the transfer efficiency is lowered.

In addition, when the ratio of organic matters is lower than 5 degrees, the sorting efficiency may be lowered, and the sorting efficiency may be maximized by adjusting the organic angle in accordance with the characteristics of the input waste. The lower limit of 0 degrees means when feeding horizontally.

The disk screen 2 drives a plurality of disks 23 at a high speed while discharging waste larger than the gap between the disk and the disk (front and rear gap between the disk and the disk) and sorting waste less than the gap.

The individual disc material of the disc screen is used as rubber, and if the size of the ring 24 for adjusting the gap between the discs is made larger than the gap between the discs, the elasticity of the rubber which is the material of the ring 24 and the disc 23 As the gap does not occur, it is possible to prevent tightness or winding by flammables (threads, films, strings, etc.), and clogging due to adsorption to organic substances is reduced, and thus continuous sorting operation is possible.

The material is rubber, which reduces the damage to glass such as bottles, and increases the recycling rate of waste.

The shape of the individual disk screen is a preferred shape having a polygonal shape (for example, hexagonal, octagonal, etc.), and may be used in a circle. The reason for this is that the disk angle of the present technology can be changed according to the shape of the waste. This is because the waste can be regularly rotated while being easily rotated.

If a disk having the above shape is installed and waste is put into the rotating body rotating at high speed, the waste of more than the set size is moved to the direction of rotation (sloping upper side) while being in contact with the rotating body. Waste is discharged to the bottom.

The scattering combustibles separating means 3 includes a blower 31 and a blow nozzle 311 installed at a lower end of the disc screen 2; An air conveyor 32 comprising a lower conveyor and an upper windshield for guiding waste and wind scattered by the blower wind; A cyclone box 33 for storing and discharging the combustibles transferred to the air conveyor; An air discharge line 34 having one side connected to the upper portion of the cyclone box and the other side connected to the inlet of the blower 31; It consists of a cyclone (35) branched at one point of the air discharge line (34) to introduce a certain amount of air and a filter (36) for purifying the air introduced into the cyclone (35) and purging it to the atmosphere.

With this specific configuration, the set size (less than 40mm-wind or water difficult to sort) on the disk screen is screened and the disk screen, which is a screening device for separating combustibles using wind power from the waste discharged through the disk screen. When the waste passed through is discharged, the blower 31 installed at the bottom of the disc screen 2 and the blow nozzle 311 connected by the tent are installed directly under the discharge end of the disc screen 2. In this way, by using the blow nozzle connected by the tent, the wind speed generated from the blower can be uniformly maintained and the wind can be blown at a constant intensity of wind and wind speed to the falling waste to effectively separate the combustibles.

If the air conveyor 32 is installed at the dropping point of heavy combustibles (fibers, rubber, wood, etc.) falling after being blown by the blowing nozzle after passing through the disk screen, the heavy combustibles may be smoothly discharged. It also prevents jams and blockages in the outlet.

When the blower air used to separate the combustibles contained in the waste (40 mm or more) passed through the disk screen is introduced through the air conveyor 32, the air discharge line 34 installed at the top of the cyclone box 33 is blown ( It is connected to the inlet of 31) to circulate the air while separating combustibles with wind power.

At this time, a part of the circulating air discharge line 34 is discharged to discharge some air, and the air is discharged to the atmosphere through the small cyclone 35 and the odor removal floater 36 to discharge the air to the atmosphere. A negative pressure is formed to prevent scattering dust and odors. When negative pressure is formed, the outside air can enter the air discharge line, but the inside air cannot go out due to the pressure difference, which prevents the scattering of dust and odor.

In addition, even though it is used for drying the combustibles by branching a part of the circulating air line by connecting a hot air blower and blowing it on the combustibles that are crushed and discharged from the secondary shredder, the negative pressure is formed in the air line to prevent scattering dust and Odor generation is reduced (not shown)

The scattering fine combustibles separating means 4 includes: an exhaust conveyor 41 driven by a driving motor (not shown) at a high speed installed under the disc screen 2; A discharge cover 42 covering the upper portion of the discharge conveyor 41 to prevent scattering of fine combustibles; A blowing nozzle 43 for blowing in the reverse direction of the discharge conveyor in the direction of discharge conveyor 41 at the end; A suction nozzle (44) installed at the beginning of the discharge conveyor (41) to suck the fine combustibles scattered by the driving of the discharge conveyor (41); A blower 45 that provides a blowing force to the blowing nozzle 43; A discharge supply line 46 connecting between the blower 45 and the blow nozzle 43; A micro combustible cyclone 47 for rotating and storing the micro combustible sucked from the suction nozzle 44 in a downward direction; A suction line 48 for discharging air introduced into the micro combustible cyclone through an upper portion of the micro combustible cyclone and connecting it to a suction port of the blower; A microflammable discharge pipe 471 on which one side communicates with a lower part of the microflammable cyclone 47 and the other side communicates with a lower part of the cyclone box 33 to discharge microflammables; One side is branched at one point of the discharge supply line 46, and the other side is connected to the fine combustible discharge pipe 471 to transfer the fine combustibles and at the same time to form a negative (-) pressure in the discharge supply line fine combustible feed branch pipe ( 461)

With such a specific configuration, the separation of combustibles contained in the small set size (40 mm or less) waste sorted from the disk screen, which is a sorting device, speeds up the speed of the discharge conveyor 41 installed in the lower part of the disk screen (high speed). It is faster than the conveying speed of the conveyor.It is a conveyor that conveys the light combustibles that are light in weight and are easily scattered by blowing or suction wind. Blowing the wind blowing nozzle (43) at one side end in the discharge cover 42 covering the upper portion of the organic material of the weight of the wind is discharged, the fine combustibles that do not win the wind is the suction nozzle (44) connected to the inlet of the blower (45) The fine combustibles are separated by rotating downward in the micro combustibles cyclone 47 and the air is a suction line which is a passage communicating upwards. The combustibles are separated while circulating to the blower 45 through the 48.

At this time, when a part of the blower exhaust air line 46 is branched and used as the air for transferring the microflammable discharged to the bottom of the microflammable cyclone 47 to the cyclone box 33, which is a combustible reservoir, a negative (-) Pressure is formed and odor is reduced.

That is, in order to subtract the micro combustibles to the cyclone box 33 through the micro combustibles discharge pipe 471, the air is generated by blowing from one side or suctioning from the other side, by constructing the micro combustibles transfer branch pipe 461 as described above. The wind discharged through the fine combustibles transfer branch pipe 461 sucks and blows the air inside the fine combustibles transfer branch pipe 461, thereby naturally transporting the fine combustibles. At this time, since the pressure of the exhaust air line 46 is lowered, negative pressure (-) is formed in the exhaust air line 46 as described above.

In addition, organic waste such as food waste discharged from the end of the discharge conveyor 41 without being sucked by the scattering after being discharged to the bottom of the disk screen is used as a raw material for landfill treatment or biogas production.

Waste (stone, glass, wood of heavy weight, steel, household appliances, etc.) that has passed the blowing force of the blowing nozzle 311 while passing through the disk screen 2 is dropped into the primary sorting conveyor 5 and is transported. Is separated by a magnetic separator (magnet, not shown) installed at the top of the primary sorting conveyor and recycled. The heavy combustibles such as wood, rubber, etc. are sorted by the secondary sorting conveyor (6) and are difficult to recycle. Is mainly buried after discharge through the primary sorting conveyor (5).

In addition, the combustibles (paper, vinyls, fibers, wood, plastics, etc.) discharged to the cyclone box 33 through the air conveyor 32 by the blowing force of the blowing nozzle 311 while passing through the disk screen 2 is secondary. Due to the relatively light weight in the sorting conveyor (6), the non-combustibles and steel materials separated by wind are sorted and separated into the primary sorting conveyor (5), and only the remaining good combustibles are discharged and crushed by the secondary shredder (7). It is manufactured as RDF, used as fuel for cement kiln, or recycled as raw material for gasification.
