Description

Pyrolysis gasification process {PYROLYSIS GASIFIER}

The present invention relates to a pyrolysis gasification furnace.

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.

An example of such a conventional pyrolysis gasification furnace is shown in Patent Document 1. [ Hereinafter, a conventional pyrolysis gasifier will be described with reference to FIG. 11 is a view showing an internal structure of a conventional pyrolysis gasification furnace.

Referring to FIG. 11, a conventional pyrolysis gasification furnace includes a cylinder 330 for receiving flammable waste including waste synthetic resin, air injecting parts 335 and 336 for injecting air necessary for combustion of combustible waste into flammable waste, air An air supply portion 351 for supplying air to the jet portions 335 and 336, a fuel input port 337 for supplying flammable waste, a cap 360 for sealing the fuel input port 337, A gas discharge pipe 370 for recovering gas from the side of the barrel 330 and a cooling means 310 installed so as not to come into direct contact with the combustible waste to cool the heat generated by pyrolysis of the combustible waste.

According to the conventional pyrolysis and gasification furnace constructed as described above, the combustible waste injected through the fuel inlet 337 is ignited and pyrolyzed. The combustible waste is pyrolyzed for a predetermined time to generate combustible gas, And then discharged to the outside through a discharge pipe 370 to be secondarily burned in a facility such as a burner furnace. At this time, an appropriate level of flammable gas can be generated by maintaining the proper temperature required for pyrolysis by the cooling means.

However, the conventional pyrolysis gasification has the following problems.

First, pyrolysis is performed by filling combustible waste in the cylinder to increase the utilization rate. At this time, in order to reach the gas discharge pipe located at the upper end of the cylinder, combustible gas generated in the initial stage of pyrolysis after ignition must pass through the waste filled in the cylinder, so it takes a considerable time for the combustible gas to be discharged smoothly. There is a problem that combustion can not be performed.

Second, the thickness of the refractory provided in the barrel is determined within a range of minimum 40 mm and maximum 200 mm according to the pyrolysis rate. If the thickness of the refractory material is too small, regardless of the pyrolysis rate, the refractory thickness is too thin If there is a high risk that the refractory material will lose its function as a result of cracking or partly falling off the pyrolysis process and the thickness of the refractory material is too thick to be more than 60 mm, the refractory material will not perform the cooling function by the cooling means, There is a risk of fire or explosion.

Third, when the waste in the cylinder is ignited, the inspection door located at the cylinder side is opened, the operator injects the ignition oil into the waste, and the ignition torch is used to manually ignite the waste. I had to continue the ignition work until the ignition occurred. As a result, there is a problem in that there is a risk of back burning to the outside of the barrel through the inspection door to cause an operator to burn, and fire may spread to the outside, leading to a large accident.

Fourth, the bottom door portion disposed at the lower portion of the barrel may be subjected to a heat pressing and buckling phenomenon due to the load pressing the waste and the central portion weakened by the heat of about 1000 캜 or more during the pyrolysis process. Accordingly, there is a problem in that a gap is formed between the cylinder and the bottom door portion, the inside of the cylinder may spread to the outside, leading to a fire, and there is a risk that the entire structure is damaged by gasification.

Fifth, in the conventional pyrolysis gasification method, when the pyrolysis process is terminated, the bottom door portion is lowered by about 1 m and moved laterally by the bogie, and then the combustion products such as the material accumulated on the bottom door portion are removed by vacuum suction The combustion products were removed. However, such a conventional removing method has a disadvantage that the air supply pipe at the lower end of the bottom door portion must be separated when the bottom door portion is lowered. In addition, since it is necessary to perform vacuum suction after spraying water before spraying the resultant combustion product to remove residual flames, it is not easy to suck the resultant of burning with water, thus making it difficult to remove the combustion products.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Examples of pyrolyzed wastes include SRF molded fuels, SULF non-molded solid fuels, biofuels solid fuels, waste tires, TDF made from waste tires in chip form, other municipal waste or industrial waste Mechanical crushing, crushing, and combustible mixed waste produced for selective recycling.

The cylinder section 10 includes a waste combustion chamber 100 having a pyrolysis space 108 in which waste is thermally decomposed, a lid 110 for opening and closing an upper surface of the waste combustion chamber 100, A check door 120 that opens and closes the check hole 124 communicating with the outside of the space 108 and a check door 120 that is disposed inside the pyrolysis space 108 while being connected to the side cooling jacket 102 to supply a combustible gas to the waste combustion chamber 100 A gas induction refrigerant pipe 130 which is provided at a lower portion of the cylinder 10 to ignite the waste and an ignition unit 140 which is provided in the pyrolysis space 108, An air supply nozzle 150 for supplying air and a gas exhaust duct 160 provided at an upper portion of the cylinder 10 to discharge gas generated by thermal decomposition of the waste, And may include a lower flange 170.

The upper portion of the pyrolysis space 108 is opened / closed by the lid 110, and the lower portion is opened / closed by the bottom door portion 20, which will be described later. In addition, when the waste combustion chamber 100 is closed by the lid 110 and the bottom door portion 20, the sealed state with respect to the outside is maintained. Accordingly, the combustion flame, gas, and the like in the waste combustion chamber 100 may not be discharged to the outside while the waste is pyrolyzed.

In addition, the waste combustion chamber 100 may be constructed by laminating the side fireproof wall 104 - side cooling jacket 102 - outer wall 106 in this order from the inside to the outside. The side cooling jacket 102 is configured to receive the refrigerant from the outside to allow the refrigerant to flow therein, and the temperature of the refrigerant flowing through the inside cooling jacket 102 can be increased by heat exchange with the thermal decomposition space 108. The heat energy accumulated in the refrigerant can be discharged to the outside and recycled.

A side fire wall 104 is disposed between the side cooling jacket 102 and the pyrolysis space 108. The side fire wall 104 is made of a material having heat insulating performance and is provided with a side cooling jacket 102 and a pyrolysis space 108, thereby preventing the refrigerant in the side cooling jacket 102 from becoming excessively high or preventing the temperature inside the pyrolysis space 108 from becoming excessively low. The thickness t of the side fire wall 104 can be determined within the range of 50 to 60 mm and the thickness t of the side fire wall 104 is determined within this thickness range, There is no danger, and the problem that the pyrolysis temperature rises too much can be solved.

The lid 110 has an upper refractory wall 112 formed inside the waste combustion chamber 100 to prevent the heat inside the waste combustion chamber 100 from being discharged upward when the lid 110 is closed. Further, the lid 110 can be easily opened and closed as one end of the lid 110 is configured to be pivotable with respect to the waste combustion chamber 100. A hinge 116 is provided at one end of the lid 110 to connect the lid 110 to the waste combustion chamber 100 so as to be rotatable with the waste combustion chamber 100. When the lid 110 is closed, A sealing member 114 may be provided on a lower surface of the lid 110 in contact with the upper portion of the waste combustion chamber 100 at a portion contacting the waste combustion chamber 100. Such a sealing member 114 can prevent the gas inside the waste combustion chamber 100 from being discharged to the outside.

The inspection door 120 is provided on the side surface of the waste combustion chamber 100 and is provided to open and close the inspection hole 124 communicating with the outside of the pyrolysis space 108.

Further, the door-side refractory wall 122 may be provided in a thickness of 200 to 300 mm and may be formed to be thicker than the side refractory wall 104. This is because the check hole 124 is a very narrow space as compared with the pyrolysis space 108 where combustible waste is accumulated and pyrolyzed and there is a risk of cranking due to cooling rather than a risk that the pyrolysis temperature of the pyrolysis waste will rise excessively It is necessary to further increase the cooling prevention effect of the internal space of the check hole 124 than the pyrolysis space 108.

The gas induction refrigerant pipe 130 is connected to both the upper and lower ends of the side cooling jacket 102 and is disposed inside the pyrolysis space 108 and is generated through pyrolysis and combustible wastes introduced into the pyrolysis space 108 So as to directly exchange heat with the combustible gas. The temperature inside the pyrolysis space 108 can be controlled more precisely by directly performing the heat exchange with the pyrolysis waste and the gas generated thereby by the refrigerant flowing into the gas induction refrigerant pipe 130 in this way. To this end, a valve (not shown) is provided in the gas-guided refrigerant pipe 130 so that the flow rate of the refrigerant flowing in the pipe can be controlled according to the internal temperature of the waste combustion chamber 100.

In this case, the up-and-down direction may be a direction perpendicular to the paper surface or a direction inclined at a predetermined angle with respect to the paper surface. Accordingly, a portion extending in the vertical direction of the gas-guided refrigerant pipe 130 is disposed so as to be spaced apart from the side-wall fire-proof wall 104, so that the gas rising space 132 can be formed.

When flammable waste is injected into the waste combustion chamber 100, pyrolysis occurs from the lower portion of the waste combustion chamber 100, thereby generating flammable gas from the lower portion of the combustible waste. At this time, the gas generated by pyrolysis rises to the upper part of the waste combustion chamber 100 and is discharged to the outside through the gas exhaust duct 160. However, the gas which is raised due to the wastes accumulated in the waste combustion chamber 100 There is a problem that it is difficult to discharge the gas smoothly.

However, according to the present embodiment, the combustible waste can be prevented from permeating into the gas rising space 132 by the gas induction refrigerant pipe 130. Accordingly, a space in which the combustible gases generated in the lower portion of the waste combustion chamber 100 can smoothly ascend to the upper portion can be secured, thereby enabling smooth gas discharge.

As shown in FIG. Thereby, the flame can be delivered only for the time required for ignition, so that even if the operator does not ignite manually, the ignition for the waste can be automatically and safely performed.
