Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a method of burning gas to be burned to an incinerator in advance so as to be able to burn efficiently to the end and to incinerate harmful gases such as dioxin without emitting as much as possible. The present invention relates to a decomposition stage, and more particularly to a furnace that thermally decomposes by electromagnetic induction by an electromagnetic coil.
[0002]
[Prior art]
Conventional incinerators include a method for burning a burnable object by injecting a gas flame into a combustion vessel after putting the burnable object in a combustion vessel, or blowing up gas upward from below and utilizing the power There was a fluidized bed type in which an object to be burned was stirred and burned. Further, there has been an induction heating incinerator in which a substance to be burned is put into a container heated by electromagnetic induction from an electromagnetic coil and burned. According to the induction heating, since only a container made of graphite or metal is heated, there are advantages such as good energy efficiency, a high heating and cooling speed, and no heat generation other than the container.
[0003]
[Problems to be solved by the invention]
In these incinerators, there is a problem that even if the incinerator is heated at a stretch, uneven burning is apt to occur, the combustion efficiency is low, and incomplete combustion is caused to generate harmful gases such as dioxin. there were. Such a problem similarly occurs in an induction pyrolysis furnace having an induction coil. In addition, according to the waste treatment law's treatment standards, it was only stipulated that burning was prohibited and burning was carried out using treatment facilities, but according to recent law revision, strong chemical toxic substances It can be said that the emission concentration standards for dioxins are strict. In order to treat industrial waste while satisfying such standards, further efficiency and more complete combustion capacity are required.
[0004]
Accordingly, an object of the present invention is to provide an incinerator having good combustion efficiency and capable of decomposing harmful gases such as dioxin without emitting as much as possible, and particularly in an incinerator having a primary furnace and a secondary furnace. An object of the present invention is to provide a pyrolysis furnace capable of gasifying an object to be burned in advance so that the secondary furnace has a high combustion efficiency and can suppress harmful gases such as dioxin as much as possible.
[0005]
Means and Action for Solving the Problems
An object of the present invention is to provide an incinerator that performs a pyrolysis stage for gasifying an object to be burned in a furnace that can be hermetically sealed. Mouth, and arrange a coil for induction heating outside the container that can be electromagnetically provided with a vent to lower the internal pressure, and a screw conveyor that conveys the burnable material in the container, A sealable shutter is provided at each of the intake, discharge, vent, and exhaust of the combustion ash (which is carbon-like) remaining after gasification. This is achieved by using an induction heating type pyrolysis furnace.
[0006]
The vent port is a port for removing air from the container, the intake port is a port for introducing a substance to be burned into the container, and the discharge port is a port for discharging combustion ash from the container. The exhaust port is a port for guiding the gasified material to be burned to the secondary furnace. After introducing the burnable substance into the container from the intake port, all the inlet, the discharge port, and the exhaust port are closed, and the air in the container is evacuated from the vent port to a vacuum or near vacuum state. Air is evacuated until the induction heating coil is energized to bring the inside of the container to a high temperature state. The burnable material in the container is conveyed to the discharge port by the screw conveyor in the container in the high temperature state. In this pyrolysis stage, the material to be burned is gasified and sent to the next secondary furnace. Note that a shutter can be provided in the opening / closing means of each port. It is also possible to provide a double shutter at the intake of the burnable material. They operate so that when one opens, the other closes.
[0007]
Since an induction heating incinerator is used in this pyrolysis stage, the combustion energy itself is electric and very clean. When an alternating current is applied to the electromagnetic induction coil, an induction current is generated in the alloy furnace placed in the coil by magnetic lines of force generated from the coil, and heat is rapidly generated. Moreover, the material to be burned is gasified in the pyrolysis stage of the primary furnace and sent to the gas incineration stage of the next secondary furnace, where it is almost completely, that is, the pyrolysis efficiency is extremely good, and dioxin and the like are obtained. They want to decompose harmful gases without releasing them as much as possible.
[0008]
The calorific value is determined by the material and mass of the container and the amount of electric energy supplied to the coil. Therefore, since the power applied to the coil can be freely adjusted, it is possible to flexibly control the disassembly.
[0009]
Now, the incinerator may be housed in a housing, and the housing may be configured to be hermetically sealable. According to this configuration, it is effective in a case where it is desired not to leak waste containing pathogenic bacteria which may cause a problem when diffused, for example, medical waste outside the incinerator. Further, gas leakage and the like can be suppressed in the housing. The shape of the housing is arbitrary, and the material may be any shape such as an iron wall surface or a concrete wall surface. Therefore, the pyrolysis furnace of the present invention can be mounted on an automobile, or a concrete wall can be used as a building itself.
[0010]
Further, the wall surface of the housing may be covered with a heat insulating material. According to this configuration, the heat generated from the cracking furnace can be blocked by the heat insulating material to prevent the heat from going out of the housing. The heat insulating material is provided along the inner and outer walls of the housing.
[0011]
Further, a sprinkler may be provided in the housing. According to this configuration, even in the event of a fire from the cracking furnace, the fire can be stopped in the housing. Sprinklers should be sprayed with water or a suitable extinguishing agent, either manually or automatically.
[0012]
By the way, the number of stages of the induction heating coil can be two or more. The amount of electric energy to be supplied can also be controlled by the number of stages. Further, the heating temperature can be changed between the first and second coils. That is, the latter-stage coil has a higher output than the former-stage coil. In this way, the first stage is thermally decomposed by the first stage coil, and subsequently the second stage is pyrolyzed at a higher temperature. Therefore, the decomposition efficiency is good.
[0013]
Next, the sealable shutter provided at each of the intake, the discharge, the vent, and the exhaust of the gasified object to be burned is described. The container is rotatably inserted into a sleeve corresponding to each of an intake port, a discharge port, a vent port, and an exhaust port of a gasified object to be burned. When the discharge port and the exhaust port of the gasified burned substance do not match the corresponding ports on the sleeve side and the bleed ports correspond with the corresponding ports on the sleeve side, the container is opened. It is possible to adopt a configuration in which a closed state is established and the inside is in a state where the inside can be evacuated. That is, it is possible to ventilate the container by rotating the container so that each of the ports coincides with the port on the sleeve side. The intake and discharge ports for the burnable material, the exhaust port for the gasified burnable material, and the vent hole have a relationship in which when one is opened, the other is closed.
[0014]
Now, it is possible to provide a sterilization unit in the introduction pipe of the burning object connected to the intake of the burning object. It is possible to sterilize the burnable material before putting it in the container. An ozonizer can be used for this sterilizing section. That is, ozone (O3) is generated and sterilized by oxygen (O) in the nascent stage.
[0015]
Further, a crushing section for the burnable material may be provided at a portion of the intake of the burnable material in the container. This is because, for example, municipal waste is included, but depending on the burnable material, finer pulverization for gasification has a higher decomposition efficiency.
[0016]
In addition, a drying unit may be provided in the vessel before the induction heating unit. This is because the decomposition efficiency of a material containing a large amount of water, such as a diaper, is better if it is dried once before gasification by induction heating.
[0017]
Next, the decomposition furnace may be provided with an ozone inlet. This is a device for making explosive combustion less likely to occur in the decomposition furnace. In other words, in this cracking furnace, the pressure inside the vessel is lowered to heat and gasify the material to be burned, but if air is suddenly introduced at the time of discharge, combustion may occur explosively. . Therefore, ozone is injected into the decomposition furnace in advance to make such a phenomenon unlikely to occur.
[0018]
Further, the screw portion of the screw conveyor may be mounted in an opposite direction near the discharge port. The burnables in the container are transported to the discharge port by a screw conveyor in the container in a high temperature state. Since the screw portion is mounted in the opposite direction near the discharge port, the carbon-like combustion ash is pushed back from here without being sent further, and is efficiently discharged from the discharge port. is there. Instead of mounting the screw portion in the opposite direction, the disk-shaped body may be mounted at right angles to the rotation axis. In this case, the carbon-like combustion ash will be blocked here, but again, since there is a discharge port, the combustion ash can be easily discharged to the outside of the container. Objective is achieved. It should be noted that the same object can be achieved by forming a screw portion that is slower than other portions only in the vicinity of the discharge port while having the same orientation.
[0019]
