Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a horizontal reforming device for biomass waste synthesis,

The present invention relates to a horizontal reforming apparatus for converting biomass waste into syngas, and more particularly, to a horizontal reforming apparatus for converting biomass waste from 1200 ° C to 1250 ° C C, thereby realizing a high-quality synthesis gas by stabilizing the reaction temperature condition occurring in the reforming furnace.

In addition, it is possible to realize a structure in which the pyrolysis gas, oxygen and hydrogen are horizontally injected horizontally through the reforming furnace in a state where the reactor is horizontally installed by reforming the reformer, By making the oxidation reaction and the reduction reaction occur uniformly, it becomes possible to improve the synthesis gas production efficiency of the reformer.

Generally, when biomass waste (combustible waste and organic waste) is heated to 400 ° C to 900 ° C in a closed state, a pyrolysis gas is generated. This pyrolysis gas contains a large amount of carbon, (CO + H ₂ ) through the reaction.

In order to produce the pyrolysis gas as described above, a structural solution is required to operate the pyrolysis gas generator in a vacuum state. In addition, in order to maintain the reaction temperature condition of the oxidation reaction and the reduction reaction constant, And the like.

On the other hand, according to the prior art, KR 10-2006-0044509 A 2006.5.16. 1, the carbonization apparatus 2 into which the biomass feedstock 1 is introduced is constituted while mounting the jacket 2a, and the carbonization apparatus 2 is constituted by a pyrolysis gas Stage gasification furnace 7 by the flow path 12 and the carbide supply means 13, respectively.

The two-stage gasification furnace 7 is formed by dividing the gas reforming section 9 and the high temperature gasification section 8 into a gas reforming section 9 and a high temperature gasification section 8, Gasifying agent supply means 14 for supplying O ₂ gas are connected.

In the two-stage gasification furnace 7 having the above-described structure, oxygen (O ₂ ) and CO + H ₂ supplied are subjected to a combustion reaction (Formulas 1 and 2).

After that, CO ₂ and H ₂ O react with the supplied carbide (4) while raising (Formulas (3) and (4)).

After that, CO + H ₂ produced on top of the two-stage gasification furnace 7 is discharged to the storage tank.

In the two-stage gasification furnace 7 constructed as described above, oxygen (O ₂ ) and CO + H ₂ supplied are oxidized, and then CO ₂ and H ₂ O are increased, And a reduction reaction occurs.

After that, CO + H ₂ produced on top of the two-stage gasification furnace 7 is discharged to the storage tank.

When the internal temperature of the two-stage gasification furnace 7 is lowered due to the heat loss due to the reduction reaction during the oxidation reaction and the reduction reaction, the means for compensating the heat loss is a two- Stage gasification furnace 7, the reaction temperature environment becomes unstable, and thus the quality of the synthesis gas produced from the two-stage gasification furnace 7 is significantly deteriorated.

Second, in a state in which the cylinder is horizontally installed by reforming the reformer, the pyrolysis gas, the oxygen and the hydrogen are injected horizontally through the torch simultaneously by reforming, and the reforming is performed along the horizontal direction from the inlet to the outlet of the reforming furnace The oxidation reaction and the reduction reaction are caused to occur uniformly, thereby remarkably improving the synthesis gas production efficiency of the reformer.

A first valve 50 is coupled to the main pipe 48 connected between the pyrolysis gas collecting tank 4 and the reforming furnace 14 and a second valve 50 is connected to the main pipe 48. In the middle of the main pipe 48, The second valve 54 is coupled while the auxiliary pipe 52 is connected and the third valve 58 is coupled to the auxiliary pipe 56 connected to the oxygen tank 40 and the hydrogen tank 42, respectively.

The heating furnace torch 20 is connected to an LP tank 44 and an oxygen tank 46 by an auxiliary pipe 62 having a fourth valve 60 connected thereto. (46) may be removed and a hydrogen tank may be connected.

The reforming torch 14 (refer to FIG. 4) has a structure in which the rear end portion is formed by a triple pipe composed of an inner tube 64, an intermediate tube 66 and an outer tube 68, The trailing end of the inner tube 64 is connected to the oxygen tank 40 and the trailing end of the intermediate tube 66 is connected to the pyrolysis gas collecting tank 4 while the connecting pipe 70 is penetratingly connected, ) Is connected to the hydrogen tank 42 while the connection pipe 72 is penetratingly connected.

The heating furnace torch 20 provided at one end of the furnace tube 18 (see FIG. 2) has the same structure as the reforming furnace torch 14, and can selectively use hydrogen and the elastomer according to the temperature change. At the same time, one side can be added to the other side of the heating furnace cylinder 18 for temperature correction assistance. The furnace torch 20, which is installed as described above, is made of a double pipe because of the use of only the LPG and oxygen.

On the other hand, the first and second thermometers 30 and 32, the first, second, third and fourth valves 50, 54, 58 and 60 and the spark plug 36 constitute information And a control unit 138 (see Fig. 6) for transferring commands while being transferred is connected.

Hereinafter, the operation of the present invention will be described.

First, when the control unit 138 transmits an operation command to the pyrolysis gas generator 2 (see FIG. 6), the pyrolysis gas generator 2 generates pyrolysis gas by heating the input solid phase component, Moves along the main pipe (48) and is stored in the pyrolysis gas collecting tank (4).

When the fourth valve 60 is opened by the command of the control unit 138 to supply the LPG and oxygen, the LPG and the Oxygen are supplied to the furnace through the heating torch 20 (see FIG. 3) 18 so that the temperature of the heating furnace 18 rises to 1100 ° C. to 1200 ° C. and the temperature of the burned gas 18 in the heating furnace 18 rises, The exhaust pipe 22 and the exhaust pipe 22 are connected to each other.

At this time, the heating furnace 18 is arranged horizontally, and the heating furnace torch 20 is configured to combust while horizontally injecting the LPG and oxygen. Therefore, the internal temperature of the furnace furnace 18 is 1100 Lt; 0 > C to 1200 < 0 > C.

Particularly, as described above, since the LPG and oxygen, which are burned while being injected from the heating torch 20, are heated while forming a vortex along the reforming tube 12, the reforming furnace 12 is uniformly There is an effect of being heated.

When the size of the reformer 6 is made large, the length of the furnace barrel 18 becomes long. At this time, the same heating furnace torch 20 is installed on the other side of the furnace barrel 18 It is possible to maintain the temperature in the range of 1100 ° C to 1200 ° C by preventing the temperature change due to the change in length.

When the second and third valves 54 and 58 are opened by the command of the control unit 138 in the above state, the oxygen is supplied to the torch 14 as a reforming gas at the same time, 14 is moved along the central passage 78 formed in the inner tube 64 and is injected through the hole 86 of the tip 88 into the reforming furnace 12 while the lypidy is passed through the heat pipe 70, Passes through the inner passage 76 of the intermediate tube 66 and is injected into the reforming cylinder 12 through the pyrolysis gas nozzle hole 84 of the head 80 while the hydrogen is injected into the heat pipe 72 Through the hydrogen nozzle hole 82 of the head 80 while being moved along the outer passage 74 of the outer tube 68. In this way,

When the gas is ignited by the spark plug 36 while the gas is being injected simultaneously with the hydrogen and the oxygen, the internal temperature of the reforming furnace 12 (see FIG. 3) rapidly rises to reach 1200 ° C. to 1250 ° C., Information on the temperature is transmitted to the controller 138 as it appears in the first thermometer 30.

The control unit 138 interrupts the second valve 54 (see FIG. 2) to stop the supply of the LPG to stop the supply of the LPG to the first reforming furnace 12, An open command is sent to the valve 50 to supply the pyrolysis gas stored in the pyrolysis gas collecting tank 10 to the torch 14 by reforming.

When a pyrolysis gas containing oxygen (O ₂ ), hydrogen (H ₂ ) and carbon (C) as a main component is injected through the torch 14 as a reforming gas as described above and is ignited at the tip of the reforming torch 14, (CO + H ₂ ) is produced as oxidation and reduction reactions such as 1,2,3) occur simultaneously.

At this time, when the reduction reaction is performed in the reforming furnace 12 as in the above formula (2) and (3), the internal temperature of the reforming furnace 12 is partially lowered .

In this state, the reforming furnace 12 continuously receives the high temperature of 1100 ° C. to 1200 ° C. from the furnace furnace 18, whereby the reforming furnace 12 is lost in the reduction reaction The heat is compensated to maintain the temperature range of 1200 ° C to 1250 ° C.

The reforming furnace 12 is disposed horizontally and installed in the furnace tube 18 to compensate for the lost heat. The pyrolysis gas injected from the reforming furnace torch 14 and oxygen and hydrogen The oxidation reaction and the reduction reaction are performed while moving along the horizontal direction, thereby satisfying the condition capable of producing a high quality synthesis gas.

The syngas generated in the reforming furnace 12 is discharged to the outside through the exhaust pipe 16 and then transferred to the syngas collection tank 10 via the radiator 8 and stored therein. Passes through the radiator 8 bent in a zigzag shape and discharges the high temperature to the atmosphere, so that the syngas moves to the synthesis gas collection tank 10 at a low temperature.

7, the reforming furnace 12 is horizontally disposed in the reformer 6 as described above, and the reforming furnace 12 is provided with a reforming torch 14 and an exhaust pipe (not shown) And an electric heater 140 is installed around the heating furnace 12 to compensate heat lost during the reduction reaction process and is connected to the control unit 138 while the reforming furnace 12 And the electric heater 140 are installed inside the heating furnace tube 18 arranged horizontally.

The inner and outer surfaces of the reforming furnace 12 and the heating furnace 18 are coated with a binder and the reforming furnace 12 and the furnace furnace 18 are provided with a through- 2 thermometers 30 and 32, respectively, and a heat insulating material 24 is installed on the outer circumference of the heating furnace cylinder 18. [

Hereinafter, the operation of another embodiment of the present invention will be described.

7) is heated by the command of the control unit 138 and the internal temperature of the heating furnace 18 is rapidly increased from 1100 ° C. to 1200 ° C. by the command of the control unit 138, Oxygen and hydrogen are injected into the reforming reactor 12 through the reforming furnace 14 and oxidizing and reducing reactions occur in the reforming furnace 12 to produce a synthesis gas, And is transferred to and stored in the syngas collection tank 10.
