Description

[0002] PYROLYSIS GASIFIER INCLUDING ASH TREATING APPARATUS [0003]

The present invention relates to a pyrolysis gasifier furnished with a reprocessor.

Disposal of various kinds of wastes such as municipal waste, industrial waste, etc. is problematic. One of the disposal methods of wastes is to classify combustible wastes such as wastes that can be used as biomass fuel including organic matter, waste synthetic resin of polypropylene series, thermally decompose them, drive the turbine by utilizing combustible gas generated through pyrolysis There is a method to utilize such as generating steam. If the combustible wastes are pyrolyzed in the gasification furnace, the emission of carbon dioxide gas can be reduced and the problem of global warming can be alleviated.

Pyrolysis gasification furnace for pyrolysis of wastes is a principle of burning local combustion by injecting air into a bottom door part where an air nozzle is planted upward and pyrolyzing surrounding waste by this combustion heat. It is also higher up to 1000 ° C or more. As a result, when the glass in the local combustion zone melts and the incombustibles and the earth are mixed with each other and cooled, a so-called crank phenomenon may occur, which hardens and forms a lump.

Hereinafter, the term " ashes " will be used in the present specification to mean whites remaining after completion of pyrolysis and lumps generated by the crank phenomenon.

In order to treat the remaining material after pyrolysis, the bottom door is connected to one side through a hinge so that the bottom door is separated from the cylinder and pivoted about the hinge. In this state, the operator scrapes down to the floor using the tool, As shown in FIG.

In this processing process, it is difficult to scrape off the lumps adhering to the floor door due to the crank phenomenon. After the floor door is closed and the operator enters the inside of the cylinder through the inspection door to remove the lumps, the bottom door is pivoted downward again It is troublesome to repeatedly perform the process of performing the process.

Due to this cumbersome operation, the time required for the reprocessing is prolonged, which hinders the continuous process, and the pyrolysis process is unnecessarily delayed, resulting in a process inefficiency.

In another conventional pyrolysis gasification furnace, the bottom door was lowered downward by using a hydraulic cylinder, and after moving in the lateral direction using a bogie, the operator cleaned the ashes. At this time, the fire door may remain partially on the bottom door even after the pyrolysis is finished. In order to remove the fire, it is necessary to spray water on the bottom door.

Furthermore, in order to eliminate the lumps generated by the crank phenomenon, a worker has to be put into the floor door. Since the temperature inside the cylinder may be high even after pyrolysis, there is a risk that the operator is exposed to the risk of burns.

However, this is only an example, and the number of the pinion gears 248 may be changed in some cases.

The pinion gear 248 can be engaged with the gear gear 320 provided in the base frame 30 to assist lateral movement of the door driving roller 243. [ The driving force of the door body 210 and the traveling means 240 is received due to the load of the material stacked on the door body 210 and the resistance of the material to the scrapers 120 of the barrel portion 10 . This drag force is overcome through the reaction force of the pinion gear 248, which is coaxially connected to the door driving member 242 and receives the driving force directly from the lever gear 320, and the door body 210 for reprocessing Can be smoothly performed in the lateral direction.

The traveling means 240 supporting the door body 210 is configured to travel in the lateral direction along the door running rail 310 through the door driving roller 243, After the combustion of the waste is completed, the door body 210 can be moved in the lateral direction and processed when the remaining material is processed.

In this regard, a scraper 120 may be formed at the lower portion of the barrel 10 so that the ash left after pyrolysis is pushed downward by the lateral movement of the door body 210 of the bottom door portion 20 to fall downward. Accordingly, the ash can be dropped to the lower side of the bottom door portion 20 by the scraper 120 formed at the lower portion of the barrel portion 10 while moving the door body 210 in the lateral direction. The material to be dropped can be transferred by the reprocessing unit 40 to be described later and processed by a method such as embedding.

The control unit may control the height of the door body 210 according to the amount of the material stacked on the upper side of the door body 210. [ The up-down means 250 can be driven. However, this is merely an example, and the elevating means 250 may be configured so that the door body 210 can be raised and lowered within a predetermined length, for example, within a range of 20 mm.

The guide post 260 is a member provided to assist the lifting and lowering means 250 having a structure susceptible to the lateral load, and the post head 264 ascends and descends depending on the lifting and lowering operation of the lifting means 250 And can have a structure resistant to transverse load. A specific description of the guide post 260 will be described with reference to FIG.

5 is a vertical sectional view and a side view showing a guide post provided in the pyrolysis and gasification furnace of FIG.

5, the guide post 260 may include a post body 261, a piston rod 262, a post head 264, a joining member 266, and an oil inlet 268. The post body 261 may have the shape of a tubular rigid column and the upper surface thereof may be opened and fixed to the upper surface of the traveling frame 241 of the traveling means 240. [

In addition, the piston rod 262 may be inserted from the upper surface of the post body 261 to be freely raised and lowered in the vertical direction. A post head 264 is provided at the upper end of the piston rod 262 and a joining member 266 joined to the side surface of the door body 210 may be provided on one side of the post head 264. [ Although not shown in the drawing, the joining member 266 may be fastened to the door body 210 through a bolt fastening method, a weld joining method, or the like.

The post body 261 may be provided with an oil injection port 268 for supplying lubricating oil and the oil injection port 268 may be formed to penetrate from the surface of the post body 261 to a space into which the piston rod 262 is inserted . Lubricating oil is supplied to the gap between the inner surface of the post body 261 and the piston rod 262 via the oil injection port 268 and the frictional force when the piston rod 262 moves up and down can be reduced. As a result, the piston rod 262 can be smoothly moved up and down with respect to the post body 261.

Accordingly, even if the door body 210 moves in the lateral direction, there is no problem such as twisting or breakage of the electric wire.

The base frame 30 is provided to support the bottom door portion 20 on the underside of the bottom door portion 20 and may be provided as a structure in which a plurality of I-beams are connected to each other. The upper surface of the base frame 30 is provided with a door running rail 310 which is engaged with the door driving roller 243 to guide the traveling of the traveling means 240. These door running rails 310 are provided in pairs in parallel with each other so as to correspond to the door driving roller 243, and can be provided as an I-beam, for example. Accordingly, the traveling direction of the traveling means 240 can be defined by the door running rails 310. [

The upper surface of the base frame 30 may be provided with a < RTI ID = 0.0 > reck < / RTI > gear 320 disposed parallel to the door running rail 310. The lever gear 320 meshes with the pinion gear 248 of the traveling means 240 to provide a reaction force to the pinion gear 248 during rotation of the pinion gear 248 so that the driving force of the door driving member 242 is transmitted to the pinion gear 248, (248) and the door driving roller (243). Thus, the load due to the interference between the ash and the scraper 120 can be overcome when the traveling means 240 for the reprocessing travels in the lateral direction.

The reprocessing unit 40 moves the door body 210 along the door driving rail 310 in accordance with the lateral movement of the traveling means 240 to receive the material falling due to the interference with the scraper 120, Lt; / RTI > To this end, the reprocessing unit 40 includes a basket 410 for receiving the dropped material, a basket driving member 420 for providing a driving force for moving the basket 410, a driving force by the basket driving member 420, A basket driving belt 440 connected to the basket driving member 420 to transmit driving force and a basket driving belt 440 connected to the basket driving member 420 through the basket driving belt 440, And a basket running rail 460 to which the basket belt pulley 450 and the basket driving roller 430 are engaged to guide the running of the basket 410.

The basket driving member 420 may be a member for generating a rotational force of a motor or the like. The basket driving roller 430 may be connected to a rotating shaft provided below the basket 410 to allow the basket 410 to run by rotation. A basket belt pulley 450 is connected to the rotation axis of the basket driving roller 430 and a basket belt pulley 450 and a basket driving member 420 are connected through a basket driving belt 440.

Accordingly, when the basket driving member 420 is driven, the driving force is transmitted to the basket belt pulley 450 through the basket driving belt 440 so that the basket belt pulley 450 and the basket driving roller 430 can be simultaneously rotated . Thus, as the basket driving roller 430 rotates and travels along the basket running rail 460, the basket 410 can move. At this time, the basket running rail 460 may extend in a direction deviating from the direction in which the door running rail 310 extends. As a result, the basket 410 is moved along the basket running rail 460 by driving the basket driving member 420, so that the ashes received in the basket 410 can be discharged to the outside.

Hereinafter, the reprocessing process of the pyrolysis and gasification furnace according to the embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. Figs. 6 and 7 are views for explaining the process of treating the ashes remaining in the cylinder of the pyrolysis-gasification furnace of Fig. 1. Fig.

Referring to FIGS. 6 and 7, when the combustion of the waste in the waste combustion chamber 100 is completed, the ashes X remain on the door body 210 of the bottom door portion 20. In order to process such material X, the elevating and lowering means 250 is driven to lower the door body 210. At this time, the degree of descent can be determined according to the amount of the remaining material X. To this end, the control unit for controlling the up-down means 250 may include sensing means (not shown) for measuring the amount of the material X . However, this is only an example, and the door body 210 may be configured to be lowered by a predetermined distance.

The piston rod 262 of the guide post 260 can also be lowered when the door body 210 is lowered by the raising and lowering means 250. [ At this time, the lubricant can be supplied to the surface side of the piston rod 262 by the oil injection port 268.

When the descent of the door body 210 is completed, the traveling means 240 can start traveling. The driving force of the door driving member 242 is transmitted to the rotary shaft provided with the door driving roller 243 and the pinion gear 248 through the door driving belt 244 The door driving roller 243 and the pinion gear 248 can start rotating. Accordingly, the traveling means 240 and the door body 210 can start traveling in the lateral direction along the door running rail 310. [

At this time, a load may be generated in the transverse direction to the elevating and lowering means 250 by the interference between the ash X and the scraper 120. This transverse load can also be dispersed in the guide posts 260. Thereby, breakage of the ascending / descending means 250 can be suppressed.

As the traveling means 240 travels, as shown in FIG. 6, the scrapers 120 formed on the lower portion of the barrel 10 and the accumulated material X interfere with each other, so that the material X can be dropped. The basket 410 of the reprocessing unit 40 is disposed at the point where the ash X falls and the dropped material X can be received inside the basket 410. [

A considerable level of lateral load acts on the lifting means 250 due to the load of the accumulated material X and the crank phenomenon generated in the course of the combustion in the process of pushing the ashes X by the scrapers 120 . If such a load acts on the lifting means 250, the lifting means 250 may be damaged.

In order to solve this problem, the guide post 260 may be provided, and the lateral load may be dispersed by the guide post 260, so that the lateral load acting on the elevating / lowering means 250 can be greatly reduced.

Also, a considerable level of resistance force is applied to the travel of the traveling means 240 due to the load of the piled material X and the crank phenomenon generated in the combustion process. The resistance force due to the material X is overcome by the reaction force acting on the pinion gear 248 from the gear gear 320. Therefore, And the traveling means 240 can smoothly run in the lateral direction. Accordingly, the processing of the ashes X can be performed smoothly despite the load of the ashes X and the crank phenomenon generated in the combustion process.

On the other hand, traveling of the traveling means 240 can continue until the door body 210 completely deviates from the lower side of the barrel 10. [ When the lateral movement of the travel means 240 is completed and the door body 210 completely deviates from the lower side of the barrel 10, most of the material X accumulated on the upper side of the door body 210 passes through the basket 410, And falls down to the inside. The thus received ash X is fed to the basket 410, The basket 410 is moved to the external processing space along the basket running rail 460 by driving the basket driving member 420 and then can be processed by a method such as embedding.

According to the pyrolysis and gasification furnace including the automatic reprocessing apparatus according to the present embodiment as described above, since the operator can automatically perform the ash treatment without the necessity of manually processing the ash, continuous operation of the pyrolysis gasification furnace becomes possible , The time required for manually processing the ash is reduced, and the process efficiency is enhanced. In addition, there is an effect that the risk of burning the worker due to the remaining fire or the like in the reprocessing process can be eliminated.
