Description

Technical Field [0001] The present invention relates to a massive fuel sorting system for reclaimed combustible waste,

The present invention relates to a sorting system for separating combustible garbage that can be recycled from landfilled combustible garbage into a mass fuel. More specifically, the present invention relates to a large-scale unsanitary landfill such as a residential land development project, When the generated garbage is generated, a natural drying plant is established to realize energy saving and fuel conversion of water and foreign matter which is an obstacle to the recycling of combustible waste (waste plastic, waste synthetic resin, etc.) Flammable waste sorting system by crusher, blow-crushing and wind-driven operation, maximizing recovery of flammable materials and recycling of soil by recycling mixed waste (combustible material, soil) Cost effective to meet F.SRF (non-forming solid fuel) specifications The quality of the combustible waste yeonryohwa on yeonryohwa mass screening system of the combustible waste landfill technology applied to natural drying process of quarrying and recycling system for precision screening.

In general, waste reclaimed from unsanitary landfill or reclaimed landfill is buried in a waste reclaimable waste material and soil and aggregate without being sorted. Therefore, the amount of reclaimed waste and its treatment cost are increased, Not only is the weight of the waste garbage high after the sorting, but also the disposal cost of the waste garbage is excessively high, and leachate, odor and scattering dust are generated in the recycled waste garbage, causing environmental pollution and being recyclable Resources are wasted.

In addition, when combustible waste mixed with waste is incinerated, flammable gas is discharged. Although such a combustible gas can be reused as a fuel, it is impossible to recover useful reusable combustible gas by a conventional incineration method, Lt; / RTI >

Therefore, waste disposal is divided into recyclable resources, combustible incineration garbage, and landfill waste. By disposing or disposing of non-recyclable garbage, it is possible to greatly reduce the amount of waste disposal, There is a need to reduce the burden of incineration or landfill by efficiently removing the impurities.

As the movement to solve these problems becomes more active, technologies such as extracting industrial oil or combustible gas using combustible waste that has been incinerated or refilled or producing alternative fuel such as solid fuel (SRF) have been developed.

However, flammable wastes do not contain only pure flammable wastes and contain various foreign substances. In particular, buried wastes contain large quantities of ash foreign matter such as soil, stones, fine powders, etc. and a large amount of water.

Therefore, the conventional technology for disposal of landfill waste requires a pretreatment process for removing various foreign substances and moisture before producing gas or producing fuel using flammable waste as well as recycling technology of soil and the like.

Conventionally, most of the techniques for removing foreign matter mixed with flammable wastes are water treatment. The mixed wastes (mixture of combustible wastes and foreign substances) are put into a water tank, and flammable wastes are washed by washing water to remove various foreign substances, Then, the combustible waste is dried using a dryer.

Therefore, the conventional technology for removing various foreign substances mixed with combustible waste requires a large facility such as a water tank and a dryer, so that a lot of energy and power are required, a large site is required, a lot of manpower is required, There is a problem that this becomes longer.

In addition, the water treatment method eliminates the adhesion between the flammable waste and the foreign material and removes the foreign material. Therefore, the efficiency of removing foreign substances is low, and the washing water used for removing foreign substances can be reused. However, since a large amount of foreign substances are mixed in the washing water, And there is a problem in that a large facility for recycling the washing water is required because the process of removing foreign substances from the washing water usually involves precipitation and coagulation of foreign matter.

The combustible waste having passed through the secondary metal separator 103 and separated from various metals is crushed in the hydraulic crusher 104 and then introduced into the primary crushing and drying separator 140.

The primary crushing and drying separator 140 crushes combustible wastes introduced through the hydraulic crusher 104 and the selective conveying conveyor 131, and separates flammable waste, soil, and foreign matter.

The separated soil and foreign substances are sequentially moved through the first circulation conveyor 151 and the second circulation conveyor 152 and then introduced into the vibration screen 130 again. In other words, the combustible waste introduced into the primary crushing and screening separator 140 in the vibration screen 130 is crushed by the primary crushing and screening separator 140 and is filtered by foreign substances such as earth to be separated again. 1 and the second circulation conveyor 151 (152) to the vibration screen (130). The foreign matter mixed with the flammable waste introduced into the vibration screen 130 again by the primary crushing and drying sorter 140 may be flammable waste that has escaped through the perforated network of the primary crushing and drying separator 140.

Through this process, it is possible to continuously separate the soil and combustible material from the perforated nets and the like, thereby enabling the combustible material to be recovered with higher efficiency.

The foreign matter containing the flammable waste, which is input into the vibration screen 130 again in the primary crushing and drying sorter 140, is separated from the weight reduction sorting device 120 and inputted to the vibration screen 130, And the foreign matter including the soil, gravel, etc.

The combustible waste that has passed through the primary crushing and drying sorter 140 can be introduced into the secondary crushing and drying sorter 150 via the discharge conveyor 105 of the primary crushing and drying separator.

The combustible wastes to be crushed in the secondary crushing and drying sorter 150 can be separated into flammable waste, soil, foreign matter, and the like. The separated soil and foreign matter may be transferred to a discharge conveyor that escapes from the secondary crushing and screening separator 150, sequentially moved to the second circulation conveyor 152, and then introduced into the vibration screen 130 again. This is a process in which soil, foreign matter, and the like separated through the crushing process in the primary crushing and screening separator 140 are introduced into the vibration screen 130 again. This process can remove foreign matter such as soil that has not been separated from the combustible waste that is crushed through the primary crushing and drying separator 140. In addition, flammable materials can be separated from combustible wastes that are clumped together with the soil.

The combustible waste that has passed through the secondary crushing and drying separator 150 is conveyed through a discharge conveyor 106 of a secondary crushing and drying separator to a dryer, a tertiary crushing and drying separator and a crusher.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It is possible to carry out various changes in the present invention.
