Figure 1 is a side cross-sectional view of a pyrolysis system equipped with a fugitive dust reduction type pyrolysis gasifier according to an embodiment of the present invention, and Figure 2 is a perspective view of a fugitive dust reduction type pyrolysis gasifier according to an embodiment of the present invention.

Referring to Figures 1 and 2, the fugitive dust reduction type pyrolysis gasifier (1) according to an embodiment of the present invention is a device for pyrolyzing waste. For example, waste (F) is input and pyrolyzed, and the top and A cylinder 100 with an open bottom, an upper door 200 provided at the top of the cylinder 100 and opening and closing the upper opening 110a (see FIG. 3) of the cylinder 100, and a bottom of the cylinder 100. and may include a bottom door 300 that opens and closes the lower opening 110b (see FIG. 12) of the cylinder 100.

Waste (F) may be input into the barrel 100 and thermally decomposed. Input waste (F) may include combustible waste. Examples of combustible waste include SRF molding fuel, SRF non-molding solid fuel, bio SRF solid fuel, waste tires, and waste tires in chip form. It may include at least one of TDF, combustible mixed waste produced for recycling by mechanically crushing, pulverizing, and sorting other household waste or industrial waste, and waste in its original state without pretreatment. However, as long as it is a waste that can be pyrolyzed, various types of waste that can be pyrolyzed can be applied.

Waste (F) can be stored in the collection point (S) by a separate transportation means (C). The waste (F) stored in the storage area (S) can be put into the barrel 100 by the grapher (G). For example, when waste (F) stored in the storage area (S) is put into the barrel 100, the lateral movement module 210 of the upper door 200 provided at the top of the barrel 100 moves. Thus, the upper opening 110a of the cylinder 100 is opened, and the grabber G can inject the waste F into the cylinder 100 through the open upper opening 110a of the cylinder 100. At this time, the grabber (G) passes through the upper opening of the cylinder 100 while holding the waste (F) and enters the inside of the cylinder 100, then releases the grip state and moves the waste (F) into the cylinder (100). ) can be placed inside.

However, the spirit of the present invention is not limited thereto, and various methods for introducing the waste (F) can be applied other than the method using the grabber (G). For example, it is possible to input the waste (F) by placing the waste in a basket using a basket conveyor, raising the waste, and pouring the waste (F) through the upper opening (110a).

The cylinder 100 may include a waste combustion chamber 110 having a pyrolysis space in which the waste F is pyrolyzed. The waste combustion chamber 110 may have a cylindrical shape with the upper and lower surfaces open. The upper part of the waste combustion chamber 110 is opened and closed by the upper door 200, and the lower part is opened and closed by the bottom door 300. You can. When the waste combustion chamber 110 is closed by the upper door 200 and the bottom door 300, it can be maintained in a sealed state against the outside. Accordingly. While combustible waste is thermally decomposed, combustion flames, gases, etc. within the waste combustion chamber 110 are not discharged to the outside.

The waste combustion chamber 110 may be constructed by stacking a side fire wall, a side cooling jacket, and an outer wall in that order from the inside to the outside. The side cooling jacket may be configured to receive refrigerant from the outside and allow the refrigerant to flow inside, and the temperature of the refrigerant flowing inside may increase as it exchanges heat with the heat generated during thermal decomposition. The heat energy accumulated in the refrigerant can be discharged to the outside and recycled.

A side refractory wall is disposed between the side cooling jacket and the pyrolysis space, and the side refractory wall may be made of a material with insulation performance. The side fireproof wall can prevent the refrigerant inside the side cooling jacket from rising to an excessively high temperature or the temperature inside the pyrolysis space from excessively decreasing by partially interfering with heat exchange between the side cooling jacket and the pyrolysis space. For example, the side fireproof wall may have a thickness within the range of 50 to 100 mm.

The upper door part 200 can open and close the upper opening 110a of the cylinder part 100. The upper door portion 200 may include a fire-resistant wall toward the inside of the waste combustion chamber 110. Accordingly, in a state in which the upper door portion 200 seals the barrel portion 100, the waste combustion chamber of the barrel portion 100 ( 110) Internal heat can be prevented from being released upward.

For example, the upper door part 200 is connected to the lateral movement module 210 and the lateral movement module 210, which closes or opens the upper opening 110a of the cylinder 100 as it moves from the cylinder 100. It may include a lifting module 220 that elevates the moving module 210.

Figure 3 is a plan view of a fugitive dust reduction type pyrolysis gasifier (1) according to an embodiment of the present invention. Referring to FIG. 3 , a configuration in which the upper opening 110a of the cylinder 100 is opened and closed as the lateral movement module 210 of the upper door 200 moves will be described. The lateral movement module 210 may be seated on the upper surface of the cylinder 100 and seal the upper opening 110a of the cylinder 100 (section (a) of FIG. 3). Accordingly, the bottom of the lateral movement module 210 may form a combustion space in which waste is burned together with the inner surface of the waste combustion chamber 110 of the cylinder 100.

In order to open the upper opening 110a of the cylinder 100, the lifting module 220 may first raise the lateral movement module 210. The lateral movement module 210 may be spaced a predetermined distance from the upper surface of the cylinder 100 by the lifting module 220 . Thereafter, the lateral movement module 210 may move in one direction (a direction away from the cylinder 100) along the lifting module 220, and thus the upper opening 110a of the cylinder 100 may be opened. (Section (b) of Figure 3). With the upper opening 110a of the cylinder 100 open, after the lateral movement module 210 completes movement in the other direction (direction approaching the cylinder 100) along the lifting module 220, the lifting module (220) can lower the lateral movement module 210 and seat it on the upper surface of the cylinder 100. Accordingly, the upper opening 110a of the cylinder 100 can be sealed (section (a) of FIG. 3). Through this series of processes, the upper door 200 can open and close the opening 110a of the barrel 100.

Figure 4 is a perspective view of the upper part of the fugitive dust reduction type pyrolysis gasifier (1) according to an embodiment of the present invention. Referring to FIG. 4, the lateral movement module 210 is, for example, selectively seated on the upper surface of the cylinder 100 to open and close the upper opening 110a of the cylinder 100, and the shaft member 224 can rotate. It may include a tightly connected sealing cover 211 and a driving unit 212 provided on one side of the sealing cover 211 and connected to the shaft member 224 to rotate the shaft member 224.

The sealing cover 211 may be configured to cover the upper opening 110a of the cylinder 100. Accordingly, at least a portion of the bottom of the airtight cover 211 and the inner surface of the waste combustion chamber 110 may form a combustion space. A fireproof wall may be provided on the bottom of the sealing cover 211 to prevent heat generated in the combustion space from being released to the outside.

For example, the sealing cover 211 contacts the upper surface of the cylinder 100 to seal the upper opening 110a of the cylinder 100, or moves in a direction away from the top of the cylinder 100 to close the upper surface of the cylinder 100. It may include a lid 211a that opens the opening 110a and a lid support 211b provided on the upper surface of the lid 211a and to which a shaft member 224 is rotatably connected.

Referring to FIGS. 5 and 6 , the lid support 211b may be provided as a separate structure connected to the upper surface of the lid 211a. As an example, the lid support 211b includes an inner support 211b-1 provided in a lattice structure on the upper surface of the lid 211a, and an outer support 211b- provided to surround the outer side of the inner support 211b-1 in the lateral direction. 2) may be included. Here, the shaft member 224 may be rotatably provided to penetrate the inner support 211b-1 and the outer support 211b-2. The inner support 211b-1 and the outer support 211b-2 may be provided with separate bearings (not shown) for smooth rotation of the shaft member 224. Additionally, the lid support 211b may be provided as a frame structure, such as a steel plate or beam.

One end of the inner support 211b-1 may be exposed to the outside of the outer support 211b-2, and the lateral movement module fixing connector 240 may be connected to the exposed end. The lateral movement module fixing connector 240 may be detachably coupled to the lateral movement module fixing part 230 provided on the upper surface of the cylinder 100. For example, when the lateral movement module 210 seals the top of the cylinder 100, the lateral movement module fixing connector 240 is coupled to the lateral movement module fixing part 230 to prevent the movement of the lateral movement module 210. It can be restricted, and when the lateral movement module fixing connector 240 is separated from the lateral movement module fixing part 230, the lateral movement module 210 becomes movable and the upper opening 110a of the cylinder 100 is opened. The driving of the lateral movement module 210 may proceed.

The lateral movement module fixing unit 230 may be optionally provided to limit the movement of the lateral movement module 210. In other words, when the lateral movement module fixing connector 240 is inserted and bound to the lateral movement module fixing part 230, the movement of the lateral movement module 210 may be restricted, and the lateral movement module fixing connector 240 may be When the binding is released from the movement module fixing unit 230, the lateral movement module 210 may be in a movable state.

For example, the lateral movement module fixing part 230 is provided to be insertable into the tie table 231 and the tie stand 231 provided with an inner space into which the lateral movement module fixing connector 240 is inserted, thereby fixing the lateral movement module. When the connector 240 is inserted into the binding table 231, it may include a binding cylinder 232 that limits the forward and backward movement and the lifting movement of the lateral movement module fixing connector 240. The binding cylinder 232 may be fixedly installed on the upper part of the cylinder 100 through a separate cylinder fixing device 232b. The pin member 232a of the binding cylinder 232 is inserted into the binding hole 231a formed in the binding table 231 when the binding cylinder 232 is driven, so that the lateral movement module fixing connector 240 is separated from the binding table 231. This can be restricted to prevent this from happening.

The lateral movement module fixing connector 240 may be rotatably hinged to the lid support 211 of the lateral movement module 210. For example, the lateral movement module fixing connector 240 includes a hinge part 241, one end of which is rotatably coupled to the lid support 211, and a locking part 242 extending in both directions from the other end of the hinge part 241. may include. Accordingly, the lateral movement module fixing connector 240 may be provided in an overall inverted “T” shape.

When the lateral movement module fixing connector 240 is inserted into the binding table 231, the pin member 232a of the binding cylinder 232 penetrates the binding hole 231a of the binding table 231 and is inserted into the binding table 231. It can be. Here, when the pin member 232a is inserted into the binding table 231 by driving the binding cylinder 232, the pin member 232a may be disposed on the upper part of the locking part 242. Therefore, the forward and backward movement of the lateral movement module 210 may be limited by interference between the pin member 232a and the hinge part 241, and the upward movement of the lateral movement module 210 may be caused by the pin member 232a and the locking part. It may be limited by the interference of (242).

Referring to FIG. 7, the driving unit 212 may be provided on one side of the sealing cover 211. As an example, the driving unit 212 may be provided on the upper surface of the lid 211a of the airtight cover 211.

Below, a detailed configuration in which the lateral movement module 210 moves to open and close the upper opening 110a of the cylinder 100 in order to introduce waste into the cylinder 100 will be described.

When the binding cylinder 232 of the lateral movable module fixing part 230 is driven in and the pin member 232a retreats in a direction away from the binding table 231, the pin member 232a may be separated from the binding table 231. You can. When the pin member 232a is separated from the binding table 231, the binding state of the lateral movement module fixing connector 240 and the lateral movement module fixing part 230 is released, so that the lateral movement module 210 can move forward and backward and up and down. It can be a state.

When the pin member 232a is separated from the binding table 231, the lifting cylinder 222 of the lifting module 220 is driven to raise the guide rail 223 and the shaft member 224. When the shaft member 224 rises, the lateral movement module 210 connected to the shaft member 224 rises and may be spaced a predetermined distance L1 from the upper part of the cylinder 100.

Afterwards, the driving unit 212 provided on one side of the sealing cover 211 may be driven to rotate the shaft member 224. For example, the drive unit 212 may be connected to the drive gear 224c provided on the shaft member 224 and the drive belt 224e, and the drive unit 212 rotates the drive belt 224e and interlocks with it to rotate the drive belt 224e. Member 224 may rotate. As the shaft member 224 rotates, the lateral movement module 210 may move at the top of the cylinder 100. In other words, when the shaft member 224 rotates, the lateral movement module 210 moves with the guide rail 223 due to gear engagement between the pinion gear 224b of the shaft member 224 and the rack gear 223a of the guide rail 223. You can receive the power to move along. The driving unit 212 may move the lateral movement module 210 a distance sufficient to completely open the upper opening 110a of the cylinder 100.

Waste may be introduced into the cylinder 100 while the upper opening 110a of the cylinder 100 is open. When the input of the waste is completed, the lateral movement module 210 can be driven in the reverse direction again and positioned up to the upper surface of the cylinder 100. When the traveling of the lateral movement module 210 is completed, the lifting cylinder 222 may be driven to lower the guide rail 223. When the guide rail 223 is lowered by the lifting cylinder 222, the shaft member 224 may also be lowered together with the guide rail 223 while being supported by the guide rail 223. When the lateral movement module 210 is seated on the upper surface of the cylinder 100, the packing provided at the lower part of the lateral movement module 210 and the packing formed along the edge of the upper opening of the cylinder 100 are pressed against each other, thereby forming the cylinder 100. ) The upper opening (110a) is sealed. At this time, the guide rail 223 may be stopped without further descending while the lateral movement module 210 is seated on the upper surface of the cylinder 100, and may be further lowered to be spaced apart from the shaft member 224. It could be. Through this series of processes, the upper part of the cylinder 100 can be sealed.

Figure 11 is a side view of a fugitive dust reduction type pyrolysis gasifier according to an embodiment of the present invention, Figure 12 is a side view showing a state in which the bottom door is lowered from the bottom door shown in Figure 11, and Figure 13 is a barrel part. It is a partial cross-sectional view showing the combined configuration of the barrel and the bottom door with the lower opening of the barrel in a closed state, and Figure 14 is a partial cross-sectional view showing the configuration of the barrel and the bottom door with the lower opening of the barrel open, and Figure 15 is This is an enlarged view of part C of Figure 12.

Referring to FIGS. 11 to 14 , a bottom door portion 300 may be provided at the lower portion of the cylinder portion 100. For example, the floor door part 300 is lifted and lowered by the support frame 310, at least one lifting means 320 provided on the upper surface of the support frame 310, and the lifting means 320, and as the bottom door part 300 is lifted, the barrel portion ( It may include a bottom door 330 that opens and closes the lower opening of the bottom door 330 and an ash processor 340 that automatically scrapes and disposes of ash remaining on the bottom door 330.

The lifting means 320 may be provided as an extendable and retractable member, and may be comprised of, for example, a hydraulic cylinder, a pneumatic cylinder, or a screw jack. The lifting means 320 may receive power from the outside and extend or contract to raise or lower the floor door 330. In addition, the lifting means 320 may be electrically connected to a separate control unit (not shown), and the control unit may adjust the height of the floor door 330 according to the amount of ash accumulated on the upper side of the floor door 330. 320) can be driven.

When thermal decomposition of waste is in progress in the barrel 100, the elevating means 320 can bring the bottom door 330 into contact with the lower surface of the barrel 100 to seal the waste combustion chamber 110 of the barrel 100. When the thermal decomposition is completed, the bottom door 330 can be lowered to open the lower opening 110b of the cylinder.

The floor door 330 can open and close the lower opening 110b of the cylinder 100 as it is raised and lowered by the lifting means 320. In order to seal the bottom door 330 and the barrel 100, a packing protrusion 140 may be provided to protrude at the bottom of the barrel 100, and on one side of the floor door 330 opposite the bottom of the barrel 100. At least a portion of the packing protrusions 140 may be provided with a packing groove 350 into which they are inserted and come into close contact.

The packing groove 350 may be provided on the upper surface of the bottom door 330 in a shape corresponding to the lower opening 110b of the cylinder 100. For example, when the lower opening 110b is provided in a circular shape, the packing groove portion 350 may be provided in a circular shape corresponding thereto. However, when the bottom door 330 is in close contact with the cylinder 100, the shape of the packing groove 350 may be changed in various ways as long as it is continuously provided to surround the edge of the lower opening 110b.

The packing groove 350 is, for example, a step part 351 formed by being recessed to a predetermined depth from the upper edge of the floor door 330, and protrudes from the inside of the step part 351 toward the lower part of the cylinder 100, The first packing rib 352 that divides the upper space of the part 351 to form at least one first heat-resistant elastic material insertion groove 353 and the first heat-resistant elastic material insertion groove 353 are inserted and coupled to the first packing rib 352 and the first heat-resistant elastic material insertion groove 353.

The remaining ash can be easily disposed of.

In other words, when the thermal decomposition is completed in the barrel 100, the floor door 330 is lowered by the lifting means 320, and the reprocessor 340 moves on the upper surface of the lowered floor door 330 and opens the floor door 330. (330) The ash on the upper surface is scraped and disposed of. At this time, if there is a protruding structure on the upper surface of the floor door 330, not only is the movement of the ash processor 340 restricted, but it is also difficult to automatically dispose of the ash loaded around the structure. Therefore, the height of the first packing rib 352 and the first heat-resistant elastic material 354 is provided to be the same or lower than the upper surface of the floor door 330, thereby making the upper surface of the floor door 330 flat as a whole, so that the ash processor It ensures easy movement of (340) and can effectively dispose of remaining ash.

For example, the first packing rib 352 has a first inner rib part 352a protruding so that one side faces the inner wall 351a of the step part 351 and a circumferential direction with the first inner rib part 352a. It may include a first outer rib part 352b that is spaced apart and protrudes to face the other surface of the first inner rib part 352a. Here, the first heat-resistant elastic material insertion groove 353 is a first inner groove 353a formed between the first inner rib part 352a and the inner wall 351a of the step part 351 and the first inner rib part 352a. ) and a first outer groove (353b) formed between the first outer rib part (352b).

The second packing rib 141 may be provided in a shape that surrounds the edge of the lower opening 110b. The second packing rib 141 includes, for example, a second inner rib part 141a provided closest to the lower opening 110b, and a middle rib part provided to be spaced apart from the second inner rib part 141a outward in the circumferential direction. It may include (141b) and a second outer rib part (141c) provided to be spaced apart from the middle rib part (141b) and the outer side in the circumferential direction. At this time, the second heat-resistant elastic material insertion groove 142 is formed between the second inner groove 142a and the middle rib part 141b and the second outer rib formed between the second inner rib part 141a and the middle rib part 141b. It may include a second outer groove (142b) formed between the parts (141c).

When the bottom door 330 rises to close the lower opening 110b, the second inner rib part 141a may be inserted into the first inner groove 353a and come into close contact with the first heat-resistant elastic material 354, The middle rib part 141b may be inserted into the first outer groove 353b and come into close contact with the first heat-resistant elastic material 354.

Upon completion of pyrolysis, the lifting means 320 may lower the floor door 330 a predetermined distance L2, and when the floor door 330 descends, the lower opening 110b of the cylinder 100 may be opened. . Ash from waste that has undergone thermal decomposition may remain on the upper surface of the floor door 330.

Figures 15(a) and (b) are respectively a side cross-sectional view and a top view of an ash processor provided in a fugitive dust reduction type pyrolysis gasifier according to an embodiment of the present invention, and Figure 16 is a plan view of a fugitive dust reduction type pyrolysis gasifier according to an embodiment of the present invention. This is a flow chart showing the process in which the reprocessor of the dust reduction type pyrolysis gasification furnace processes ash.

15 and 16, the ash processor 340 is a device that pushes and controls the ash (X) remaining on the floor door 330 while traveling in one direction, for example, the body frame 341, A driving gear 344 connected to the body frame 341 and configured to engage with the rack gear 344b, a driving member 342 connected to the driving gear 344 to provide rotational force to the driving gear 344, and driving A drive belt 343 that connects the member 342 and the drive gear 344 to transmit the power generated by the drive member 342 to the drive gear 344, and a first driven wheel coaxially connected to the drive gear 344. (345), a second driven wheel 346 having a different axis from the first driven wheel 345, a scraper 347 and a body provided at the front of the ash processor 340 to push out and process the ash (X) It may include a brush 348 provided at the lower part of the frame 341 and provided to sweep the upper surface of the floor door 330 when the reprocessor 340 moves. In this embodiment, the case where the drive member 342 and the drive gear 344 are connected through the drive belt 343 is described as an example, but it is also possible to use a drive chain in addition to the drive belt. When the drive member 342 starts operating, the reprocessor 340 begins linear movement as the drive gear 344 rotates and moves forward along the rack gear 344b. At this time, it is driven by the travel guide 344a. A driving path can be set by guiding the wheels 345 and 346. Here, the traveling guide 344a may be provided on the side of the I-beam. For example, the traveling guide 344a may be defined as a “ㄷ” shaped space in cross section forming the side of the I-beam. A driving path can be set by accommodating the driven wheels 345 and 346 in this “ㄷ” shaped space.

The scraper 347 may be made of a metal material or a resin material that has relatively greater rigidity than the brush 348. At this time, the lower end of the scraper 347 may be spaced a predetermined distance from the upper surface of the floor door 330 to prevent interference by structures, etc. when moving and to prevent friction with the upper surface of the floor door 330. .

The brush 348 may protrude from the lower surface of the body frame 341, and its lower end may be in contact with the upper surface of the floor door 330.

In this way, the ash processing efficiency can be improved by providing the scraper 347 and the brush 348 together. In other words, a large amount of ash on the upper surface of the floor door 330 can be processed with the scraper 347, which has relatively large rigidity and size, and the ash on the upper surface of the floor door 330 that has not been processed by the scraper 347 can be disposed of. Ash remaining adjacent can be disposed of through the brush 348.

The flying dust prevention cover 400 can prevent flying dust generated in the process of discharging ash remaining on the floor door 300 from leaking to the outside. The flying dust prevention cover 400 may be provided on the lower side of the cylinder part 100. For example, the flying dust prevention cover 400 may be provided to surround the bottom door part 300. In other words, the floor door portion 300 may be disposed in the inner space of the dust prevention cover 400. The flying dust prevention cover 400 can be connected to a separate prevention facility, and dust scattered inside the flying dust prevention cover 400 can be removed by being sucked through the collection hopper 410. At this time, the flying dust sucked through the collection hopper 410 can be removed by being transferred to a separate prevention facility consisting of a cyclone, bag filter, stack, etc. However, this is only an example, and the collection hopper 410 may be connected to the burner 130. In other words, the flying dust sucked through the collection hopper 410 flows into the burner furnace 130 and is mixed with the combustible gas introduced from the cylinder 100 to be processed and burned, and the unburned dust is removed through the back-end prevention facility. It can be.

Meanwhile, the cylinder part 100 may be provided in communication with the burner furnace 130 through the gas duct 120. Combustible gas generated during thermal decomposition of waste may be supplied to the burner furnace 130 through the gas duct 120 and may be burned in the burner furnace 130 to generate waste heat.

Additionally, the burner furnace 130 may be connected to a waste heat boiler (not shown), and the waste heat boiler may recover waste heat generated in the burner furnace 130 to generate steam. Combustion gas passing through the waste heat boiler passes through a downstream prevention facility consisting of one or more of the equipment facilities such as a semi-dry reaction tower (SDR), bag filter, scrubber, non-catalytic reduction device (SNCR), and catalytic reduction device (SCR). After contaminants are removed, they can be discharged to the outside through the stack.
