Description

TECHNICAL FIELD The method for pre-treatment of living waste including multi-tearing the waste envelope and screening processes and apparatus thereof

The present invention relates to a method and apparatus for pretreatment of household wastes including multiple demolition and sorting processes, and in detail, crushing only combustibles in a state where incombustibles are removed as much as possible through a multi-demolition and sorting process for household wastes of various characteristics contained in a pay-as-you-go bag, It relates to a technology that enables the production of non-molded solid fuel with high efficiency by grinding.

In general, waste treatment uses methods such as landfill or incineration.However, the life of existing landfill sites is nearing amid environmental problems and difficulties in securing additional landfill sites, and the incineration method is also due to the discharge of environmental pollutants such as dioxin. Since additional construction is not easy, waste treatment is emerging as a major social problem.

Recently, in order to solve this problem, various non-molded solid fuel manufacturing technologies have emerged that can select and convert combustible materials including tires, vinyls, and plastics contained in waste to be landfilled or incinerated. This non-molded solid fuel manufacturing technology is a very desirable phenomenon in terms of recycling wastes as high-calorie renewable energy along with the advantage of reducing the amount of waste to be landfilled or incinerated.

Non-molded solid fuel is a cement factory by converting waste synthetic resin, waste rubber, and waste wood, which were previously simple incinerated or buried into a resource, to a level similar to coal calories (4,000 to 5,000 ㎉/kg) by improving transport, storage and combustion stability. It is a new and renewable energy used as auxiliary fuel for thermal power plants. Since non-molded solid fuel consists of only combustibles with high calorific value and generates even heat during incineration, it is used in various ways in dedicated power plants and industrial boilers, and also produces steam and supplies it for heating and cooling in each region.

As a conventional solid fuel related technology, Korean Patent No. 10-0998800 solves the problem of sediment removal and odor of high quality waste synthetic resins that can be recovered from landfill waste, and simplifies the resource of such landfill waste. In presenting a means of active recycling of the problem of passive energy recycling that is recovered as a heat energy source by incineration, the integrated treatment of landfill waste and recycling resources of domestic waste by providing the characteristics of the process that can be linked to the existing MBT process As a technology that produces high-quality solid fuel by mixing each recycled resource, it is an integrated process that connects the recycling treatment of landfill waste in the MT process of household waste. S-A1) PLC that controls and monitors each process overall. A first sorting process of separating combustible materials from domestic waste after crushing and crushing the imported domestic waste with a first crushing crusher and passing through a first sorting device by process control; S-B1) a second sorting process of separating combustible substances from the landfill waste after crushing and crushing the landfill waste separately brought in from the household waste with a second crushing crusher and passing through a second sorting device. .

In addition, Korean Patent No. 10-1021754 solves the problem of sediment removal and odor of resources such as high-quality waste synthetic resins that can be recovered from landfill waste, and simply incinerates the resources of these landfill wastes as a heat energy source. In presenting the means of active recycling, the problem of passive energy recycling to be recovered, the characteristics of the process that can be linked to the existing MT process of household wastes are prepared, and the recycling resources of landfill and household wastes are integrated and processed to each recycled resource. It is a technology that produces high-quality solid fuel that is mixed with water.It is an integrated process that links the recycling treatment of landfill waste in the MT process.The first destruction of household waste by the process control of PLC that controls and monitors each process overall. A first sorting process of separating combustible materials from domestic waste after breaking and crushing with a crusher and passing through a first sorting device; A second sorting process of crushing and crushing the landfill waste separately brought in from the household waste with a second crushing crusher, passing through a second sorting device, and separating combustible substances from the landfill; The moisture content of the combustible mixture mixed in the storage tank by controlling the moisture content measurement device of the sorting mixture storage tank that temporarily stores the combustible materials and the combustible materials of landfill waste separated through the first and second sorting processes. When the content is less than 10%, it is supplied in the following steps, and when the moisture content is more than 10%, the sorting mixture storage and the primary moisture content control process are controlled to be supplied to the third sorting device.

In addition, Korean Patent No. 10-1270936 does not require large-scale facility investment in producing solid fuel by using combustible materials from household waste, and is energy-saving by effectively utilizing hot air in a wind separator, and ensuring equal quality of waste. It is a solid fuel manufacturing technology for domestic waste and landfill waste using an improved double drying system and double exhaust gas treatment system to ensure efficiency and economy in terms of energy consumption. A first sorting step of separating non-combustible metals with a magnetic separator after sorting according to particle size with a screen, and selectively sorting combustible waste for each repair; Incombustible materials are separated and stored in a box by separating household waste and combustible materials from landfill waste separated through the first sorting process by a wind separator connected with a dry hot air fan, and only combustible materials are selected to have a moisture content of 10% or less, or 25%. A first drying step of hot air drying with a combustible material having the following moisture content; Comprising: a pulverizing step of pulverizing the combustible material introduced through the first drying process to produce a non-molded RDF having a moisture content of 25% or less, or a molded RDF having a moisture content of 10% or less; It's technology.

However, the conventional solid fuel manufacturing techniques as described above are various characteristics of household wastes of various characteristics contained in a pay-as-you-go bag that local governments collect and transport household wastes generated in each household and brought into the treatment plant, or various characteristics contained in sacks of natural or synthetic resins. In the case of temporary large amounts of waste, the entire facility is stopped due to damage to the shredder due to incombustibles (ferrous metals) mixed inside, or environmental pollution because non-combustibles and combustibles contained in pay-as-you-go bags or sacks are not properly sorted out. There is a structural disadvantage in that (leachate, odor, pests, etc.) is generated, and management costs increase due to an increase in waste.

As a result, solid fuel is buried as impurities during the screening process after crushing, causing a large economic loss in terms of resource utilization.

In addition, the conventional method of producing solid fuel through a waste sorting process has a disadvantage in that excessive energy is consumed because a drying process using a dryer for reducing moisture content is included.

Hereinafter, the configuration and operation of the embodiments of the present invention will be described in detail in conjunction with the accompanying drawings. In addition, in describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a perspective view showing the overall configuration according to an embodiment of the present invention, Figure 2 is a plan view showing the overall configuration according to an embodiment of the present invention, and Figure 3 is an overall configuration according to an embodiment of the present invention. It is a front view shown, and FIG. 4 is a perspective view showing a detailed structure of a quantitative wave waveguide according to an embodiment of the present invention.

As shown, according to the present invention, the pretreatment device for living waste is mainly installed indoors (possible outdoor), a quantitative supply wavebreaker (1), a wavebreaking and particle size sorter (2), a first wind power specific gravity separator (3), and a blow type. It consists of a crusher (4), a disk sorter (5), a suction wind speed control cyclone (6), a second wind specific gravity sorter (7), a crusher (8), and a de-branch (9).

In addition, a magnetic separator 10 is further included in the process of connecting the devices.

The waste supplied to the quantitative supply stalker (1) is the primary crushing and crushing while crushing the volume-based bags carried into the treatment plant using the tongs of an excavator (not shown), the temporary large amount of waste contained in the sacks of natural or synthetic resin materials, etc. It is a state of waste.

It is well known that each of the above devices is configured to convey the sorted waste to the next stage device through various horizontal or inclined conveying lines, such as a conveyor driven by a motor.

The quantitative supply wave breaker (1) is not shown by receiving the primary breakage and crushed waste while pounding the excavator's tongs for various types of household wastes or temporary large-scale wastes contained in a pay-as-you-go bag or sacks of a treatment plant. A vibration hopper 110 for quantitatively moving through the vibration plate 111 vibrated by the vibrating device; A wave breaker 120 positioned stepwise below the end of the vibration hopper is integrally configured.

The crushing machine 120 is one of a plurality of rotating blade disks 1201 having a plurality of blades 1201a formed along the circumference on a single disk, axially coupled at narrow intervals on a single rotation shaft 1202 and arranged in the width direction. It is composed of columns.

In addition, the row consisting of the one rotating shaft is arranged in a plurality of rows in the longitudinal direction, and the rotating blade discs 1201 axially coupled to adjacent rows in the longitudinal direction are arranged to be staggered with each other.

The plurality of rotary blade discs 1201 are formed in a form in which only a portion of the upper part protrudes from a plurality of slits 1204 formed alternately on the surface of the plate 1203 formed on the upper part of the digger, so that wastes do not fall downward and are discharged to the end of the digger. It is structured.

The rotation shafts are configured to be gear-coupled with a rotation shaft of a row adjacent in the longitudinal direction by coupling a gear at one end, and the power shaft is configured to rotate by applying power to only one of the rotation shafts. The gears are rotated in a direction opposite to the rotational direction of the power shaft in a state of being bitten, so that the rotational direction of the adjacent rotational shafts is reversed and rotated.

In one embodiment, when the rotation shaft of the third row is rotated forward in the waste discharge direction, the first two shafts are sequentially paired and rotated downward, thereby causing a wave breaking action.

As described above, the vibration hopper 110 and the crushing machine 120 constituting the quantitative supply wave breaking machine 1 have the same or similar inclination angle between the vibration plate 111 of the vibration hopper and the plate 1203 of the wave breaking machine 120. It is formed to have a step.

For this reason, the bags and the sacks containing the primary crushed and shredded waste supplied to the vibration hopper 110 move along the inclined surface by the vibration of the vibration plate, and are broken at the end of the vibration plate 111 in a sequentially aligned state. It falls to the plate 1203 of the upright 120.

Subsequently, in the pulverizer 120, the direction of rotation between neighboring shafts is continuously reversed, and at the same time, the rotating blade discs 1201 axially coupled to the neighboring rows are arranged alternately. And it is secondarily ruptured or torn by the rotating blade disc 1201 disposed alternately.

For this reason, in the state where the excavator's tongs were first sacked in the previous step, incombustibles and combustibles contained in the bag and the bag bag made of natural or synthetic resin are not completely crushed and peeled off, so that the rotating blade disc 1201 of the crushing machine 120 As the provided area is sequentially moved, the bag and the bag bag are continuously sacked or peeled off, thereby exposing the incombustibles and combustibles, thereby enhancing the sorting efficiency.

Thereafter, the waste discharged to the end of the crushing machine 120 is transferred to the drum rotary crushing and particle size sorting machine 2 through a transfer conveyor.

The drum rotation type pulverization and particle size sorting machine 2 has a structure in which a rubber sorting net (or sorting drum) perforated with a trommel sorting machine and a plurality of blades (not shown) protruding and arranged in the center of the sorting net are installed. It is a device that classifies wastes while performing the process of second sacking the unbreakable bags and sacks surrounding the wastes supplied through the quantitative supply sacking machine (1).

At this time, the rubber sorting net (or sorting drum) also serves to reduce noise and dust while preventing clogging of the net by elasticity.

For reference, the drum rotation type crushing and particle size sorting machine 2 has a structure in which the size of the perforation required for the circular perforated net is discharged to the bottom, and the waste larger than the perforated net is passed through. Through this, household wastes of various characteristics that have been put into the circular sorting machine are sorted by size.

In addition, the drum rotation type perforation and particle size sorter 2 may be configured as a perforated network of various sizes by configuring a circular perforated network in multiple stages as needed. Of course, even a single circular perforation network can be configured with different perforations in the longitudinal direction.

The air circulation type first wind power specific gravity sorter 3 is a device for sorting into combustibles and non-combustibles by a wind power specific gravity sorting method that reuses air for wastes of a certain size or more discharged from the drum rotation type pulverization and particle size separator 2.

In other words, combustibles with specific gravity blown by the wind are sorted and discharged through the pulverization process using the grinder 8, and non-combustibles such as iron products, foods such as fruits, etc., which fall after defeating the wind, are about 750rpm. It is a device that sends it to a high-speed hitting type crusher that rotates at high speed for the fourth break.

The high-speed blow crusher (4) is a type of impact crusher that not only crushes and crushes non-combustibles such as iron, food such as fruits, and unsealed bags or sacks, but also crushes wastes such as porcelain contained in non-combustibles. You can be reconciled. Porcelain is a waste material that can be converted into high-quality soil as a resource because it is made of soil and sand.

A magnetic conveyor type magnetic separator 10 may be installed at the point discharged from the high-speed blow type crusher 4 to remove irons contained in the shredded incombustibles.

In addition, magnetic drum or magnetic conveyor type magnetic force on the transfer line that supplies incombustibles that could not be supplied to the air-circulating first wind power specific gravity sorter (3) due to the specific gravity after discharge from the drum rotary type crushing and particle size sorting machine (2) It can be configured to remove iron in advance by installing the sorter (10).

Also, the disks on the adjacent shaft are configured to be staggered with each other.

In addition, the size of the sediment can be controlled by adjusting the distance between the disc and the disc and the distance between the disc and the size of the soil discharged to the bottom and the waste discharged to the end. In this way, the disc sorter constructed using the disc is cut thinly when the disc rotates, and is discharged to the bottom or transferred to the end, even if the soil has a high moisture content.

In one embodiment, the above-described disc sorter discharges soil of 15 mm or less to the bottom and waste discharged to the end may be adjusted to a size of 15 mm or more. However, such numerical values do not limit the present invention.

The suction wind speed control cyclone 6 is a device that removes fine foreign matter so as to produce soil of a certain size or less discharged to the lower portion of the disc sorter 5 as high quality soil.

The suction wind speed control cyclone is discharged to the lower part of the disc sorting machine and flows fine combustibles contained in the soil being transported through a conveying line made of a conveyor into the inside of the cyclone 62 by the suction power of the suction pipe 61, and then rotates downward to the lower part of the cyclone. By discharging, passing through the disc sorter, and discharging toward the waste of a certain size or more being discharged through a transfer line, and configured to be transferred together.
