Technical Field [0001] The present invention relates to a pretreatment apparatus and a pretreatment method for a byproduct of a palm tree,

The present invention relates to a pretreatment apparatus and a pretreatment method for a system for converting an EFB (Empty Fruit Bunch) into a fuel by harvesting pulp from a fruit in a palm tree (PALM TREE).

Palm tree fruit is used in various fields. The palm kernel fruit has been developed to use palm oil obtained by milking the pulp for a variety of foods, and a method for using it as a pulp raw material is also being developed.

Palm trees are mainly cultivated mainly in Southeast Asia, such as Malaysia and Indonesia. The amount of EFB that is removed from the pulp is increasing, and the surrounding environment is becoming more disturbed. In recent years, It is being tried.

Palm tree fruit is used or developed in various industrial fields. Palm trees are grown in Southeast Asia in large quantities. However, due to the large amount of palm trees cultivated, EFB is more likely to occur. .

As part of this EFB treatment, there is an attempt to use EFB as fuel, and some fuel is being used.

It is generally known that EFB contains more than 60% moisture and various types of metal compounds. In order to use such EFB as a fuel, it is necessary to remove foreign substances such as various metal compounds that increase the generation of moisture and soft materials and contaminated soil during the harvesting process to obtain satisfactory fuel efficiency.

Therefore, in order to fuel EFB, many EFBs are simply incinerated because dehydration and drying system for removing water and a cleaning facility investment for removing foreign substances such as soil are required to be expensive.

In addition, a large amount of various metal compounds contained in the EFB cause another problem of lowering the combustion efficiency by generating a large amount of burned material at the time of burning and lowering the reflux point to form a clinker by burning the boiler.

In order to overcome such problems of the prior art, Japanese Patent Laid-Open No. 10-2006-0032495 proposes a method of pulping by-products of palm tree. However, there are limitations on the pulping of palm wood byproducts, and therefore, there have been various studies to reduce the amount of burned material to make fuel.

The inlet side sprockets 36 and the outlet side sprockets 38 are electrically connected to the chains 46 and 48, respectively, so that a total of four sprockets are simultaneously rotated.

The frame 40 is installed so as to protrude upward from the water tank 10 and a plurality of openings 50 are formed at an upper portion thereof so that the inside of the water tank 10 can be seen, . A transparent member made of a synthetic resin material may be provided in the opening 50.

A plurality of scrapers (52) are suspended in the chains (46) and (48).

The scrapers 52 according to the embodiment of the present invention include a straight portion 54, an inclined portion 56, and a ring portion 58 as plates having a thickness of about 3 mm as shown in FIGS. 7 and 8 .

A plurality of holes 60 are drilled in the linear portion 54 to minimize movement resistance when moving in the water of the water tub 10.

The inclined portion 56 is formed at a lower end portion of the scraper 52 and moves in contact with the bottom surface of the water tub 10 so that foreign matter on the floor surface can be easily scratched and moved. (Not shown).

An annular ring portion 58 is provided on both sides of the scraper 52. The annular portion 58 is used as a means for suspending the scrapers 52 on the chains 46 and 48.

9, the shaft 64 is inserted into the annular portion 58 of the scrapers 52 and one end of the shaft passing through the annular portion 58 is inserted into the hole formed in the chain 48 will be. Although only the right side of the scraper 52 is shown in the drawing, the left side has the same structure.

5 and 6, the scrapers 52 are mounted on the chain at predetermined intervals in a suspended state on the chains 46 and 48. As shown in Figs.

A plurality of scrapers 52 may be suspended on the chains 46 and 48 and the chain may be bent downward due to the self weight of the scrapers. In the embodiment of the present invention, A plurality of rollers 66 are rotatably mounted on the frame 40 so as to contact the lower side of the chains 46 and 48.

In the pretreatment apparatus according to the embodiment of the present invention as described above, the water tank 10 is first filled with water. The height of the water to be filled in the water tank 10 is preferably approximately the horizontal line shown in Fig. This horizontal line is approximately the same as the height of the inclined member 30.

When the water is supplied to the water tank 10, the micro bubble generator 16 is operated to cause a large amount of micro bubbles to be generated in the water supplied to the water tank. At the same time, the compressor 18 is operated to generate another bubble.

When the water P is filled in the water tank 10 and the byproduct P cut in the by-product storage and cutting device 2 is inserted into the water tub 10, the water P moves along the guide member 28, 10) into the water filled in.

The by-product P supplied to the water in the water tank 10 will be partially submerged and partly submerged. As time goes by, the amount of sinking by-products (P) will increase.

As described above, various metal compounds having a large ionization tendency contained in the by-product (EFB) of the palm tree supplied to the water are removed by water and separated from the by-product (P).

At the same time, since the by-product (P) is in water, the soil and foreign substances on the surface start to fall off the by-products.

In this state, when a rotational power is transmitted to the sprockets 36 and 38 through a motor (not shown), the chains 46 and 48 rotate and a plurality of scrapers 52 suspended in the chain move do.

These scrapers 52 are linearly moved in the section between the front sprocket 36 and the rear sprocket 38 and move circularly as they pass the sprockets 36 and 38.

4, the upper side scrapers 52 are suspended from the upper chain so that they are not in contact with the water in the water tank, but the scrapers 52 on the lower side chain are not contacted with the water in the water tank, The slope portion 56 is in a position in contact with the bottom surface of the water tub 10, so that it is in a state of being linearly moved while being immersed in water.

The scrapers 52 hanging on the upper chain are moved to the left in the view of FIG. 4 and are hooked on the shaft 42 on which the sprocket 36 is installed during the movement, The lower end of the scraper 52 is caught by the shaft 42, and the annular portion 58 rotates as the chain moves.

In this way, the upper scrapers 52 are moved downward, and the lower end of the scrapers 52 can contact the bottom surface of the water tub 10.

The scrapers 52 in contact with the bottom surface of the water tank 10 move in the rightward direction as viewed in FIG. 4, pushing the by-products P and the foreign substances on the bottom surface of the water tank.

Then, the by-product P partially submerged in the water of the water tank 10 is also pushed as the scrapers 52 move.

In this process, fine bubbles generated from the micro bubble generator 16 blow off from the surface of the by-product P, thereby separating soil or foreign matter on the surface of the by-product. The effect of separating the foreign matter is further enhanced by such a micropore.

At the same time, compressed air is supplied into the water tank 10 by the compressor 18, so that water in the water tank vortices and bubbles are generated at the same time, so that foreign matter and soil in the by-product P can be completely removed.

In addition, due to such bubbles and eddy currents, metal compounds with a high ionization tendency are completely removed from the byproduct (P) by ionization reaction with water.

When one scrapper among a plurality of scrapers is described as an example, when the scrapers 52 on the side of the inlet side sprocket 36 reach the outlet side sprocket 38 while performing a series of operations, most of the foreign matter and the ionization tendency And the large metal compound will be separated from the by-product (P).

The byproducts are lifted up the inclined surface 32 of the inclined member 30 while being pushed by the inclined portion 56 formed at the lower end of the scraper 52.

At this time, since the scrapers 52 are rotatably installed on the shafts 64, the scrapers 52 are inclined as shown in FIG. 4, and the by-products are pulled up and dehydrated simultaneously by the weight of the scrapers 52.

As the operation progresses, the by-product P drawn up when the slope member 30 reaches the downward inclined surface 34 is moved downward along the inclined surface of the downward inclined surface to be transferred to the drying apparatus 6 will be.

Foreign matter such as soil scraping and transporting the scrapers 52 on the bottom surface of the water tank 10 can be discharged along with the water along the water pipe 26 while falling into the grooves 24 formed in the bottom surface of the water tank.

When the discharge screw is provided in the groove 24, the foreign matter can be discharged more easily.

This action removes a variety of metal compounds and soil contaminants in the EFB.
