Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended for combustible wastes in which various synthetic resins and papers are inseparably mixed, or some high-waste wastes such as raw garbage and disposable diapers are mixed. The present invention relates to an apparatus that does not generate an abnormally high temperature by performing smokeless and odorless combustion processing and that can use a combustion flame as a boiler heat source or the like.

2. Description of the Related Art A combustible waste combustion furnace is known as an application scene for a solid fuel combustion furnace. However, conventionally, primary combustion is mainly performed by excessive air supply, and the air ratio is generally 5 to 20. The average flame temperature was low, but secondary air was also used, but only to a supplementary level. In that case, it is difficult to maintain the primary combustion uniformly, the temperature inside the furnace is not uniform, and an abnormally high temperature is generated in part to deteriorate the heat resistance and durability of the furnace, especially when synthetic resins are mixed. Yes, on the other hand, it produced smoke from incomplete combustion. There is also an apparatus designed to escape from that stage. For example, a method in which a sufficient amount of secondary air is made to flow in an annular manner from a thin nozzle is used to suck the generated gas pyrolyzed with a small amount of primary combustion air, -By gradually performing a combustion reaction from the outer circumference like a flame of Soku, for example, by the condition that the air ratio of the primary combustion is about 0.4 and the total air ratio is about 1.3, it becomes smokeless at a high flame temperature. There was a device capable of stable gas combustion (Japanese Patent Application No. 5-57483).
However, in the case of a relatively low water content material containing a high proportion of carbon, such as rice husks and bark, it worked well, whereas a material that mixes synthetic resins and high water content waste at a high rate. In some cases, there is a problem that it cannot withstand use, and when the temperature in the furnace for ignition or fire extinguishing is low, secondary combustion cannot be done for a short time (about 20 minutes) and smoke is generated, so basic improvement is necessary. And

[0003]

[Problems to be Solved by the Invention] Combustible wastes such as rice husks, bark, and wood wastes generated in agriculture and forestry are homogeneous low-moisture materials containing carbohydrate as a main component, and therefore,
The raw material is thermally decomposed at a constant rate by the amount of heat that burns a part of carbon by the supply of an extremely small amount of primary air, and volatile gas is stably generated. By the action of the annular secondary air flow from the thin nozzle. Although it burned gas well, in modern society, there is a strong demand for a device that disposes of industrial waste generated in cities easily and harmlessly, rather than a device that effectively uses the waste from agriculture and forestry. Then, it is necessary to meet social demand. However, in that case, the target flammable waste raw material is originally coarse, so special treatment is required, and it is common to mix synthetic resins at a high rate so that abnormal high temperatures do not occur. When the amount of primary air is limited as described above, when there are many components that are liquefied during the thermal decomposition process such as polyethylene and styrol, the amount of heat necessary for further gasifying the liquid is insufficient, and the amount of heat is sent to the furnace bottom. Accumulated in sequence, impeding the thermal decomposition action, and increasing smoke generation time at the time of fire extinguishing, which is a problem, and other synthetic resins needed a new solution to stabilize gasification in primary combustion. In addition, it is more effective if high-moisture waste such as garbage and disposable diapers can be mixed and processed at the same time, but the amount of heat required for evaporation of water is insufficient and the pyrolysis gasification is impeded. A solution was needed. Moreover,
Immediate response was required because the mixing ratio of synthetic resins and high-moisture waste varies depending on the treatment plant and the mixing ratio may change over time. Furthermore, the problem of smoke during ignition and extinguishing was not a problem in agriculture and forestry, but it was a problem that needed to be solved in overcrowded cities.

In order to solve these new problems, a new means for drastically improving the conventional device was needed. The present invention addresses these new issues.

A vent is provided at the bottom of the primary combustion chamber, an ash outlet is provided at the bottom side, and a raw material hopper is provided at the upper side. Connect the openings, and install a thin nozzle in an annular shape over the entire inner circumference to the connecting portion of the cylindrical opening and the secondary combustion cylinder, or install the thin nozzle in a part of the connecting portion in a spiral direction in contact with the inner circumference. Then, the start end of the nozzle is connected to an air passage, and the vent hole and the air passage are connected to separate air ducts to regulate the air volume from the blower,
In a gasification combustion furnace apparatus in which the amount of secondary air passing through the air passage is sufficiently larger than the amount of primary air passing through the vent, one end is connected to the raw material hopper and the inclination is near the angle of repose. Is provided in the primary combustion chamber, the grate is configured as a ventilation port A, and the ventilation port B is provided at a position slightly above the wall surface of the primary combustion chamber facing the tip of the grate and passing through the ash drop gap, A ventilation port C is provided below the ash removal gap, that is, the ventilation port is
Basically, the problem is solved by categorizing and arranging into 3 types of C and subdividing each air flow rate to an appropriate ratio. For example, normally, the ventilation amount distribution is about 0.5 for the vent A and about 0.5 for the vent B.
3. The air vent C is regulated so that the remaining 0.2 place is left. However, in the case of the target raw material in which the synthetic resins are always mixed at a high rate, the ash dropper is configured in the tray below and the air flow rate of the vent C It is advisable to adjust the distribution so that the air flow rate is increased to 0.4 and the air vent B is left at 0.1. To regulate the ventilation amount, it is sufficient to install a number of ventilation small holes in proportion to the ventilation amount distribution for each ventilation port arranged for 3 minutes, but it may be variable by a control valve or the like. Further, a raw material feed rack that slides back and forth toward the grate may be provided on the lower surface of the raw material hopper.

From an auxiliary tank for liquid fuel such as waste oil or solid fuel such as bark pellets, a transfer pipe is connected and opened to the primary combustion chamber through a shutoff valve, and a shutoff valve is controlled by a timer to open and close the shutoff valve. The problem is supplemented and solved by providing a device so that a required amount of liquid fuel or solid fuel can be supplied into the next combustion chamber when needed. At that time, a temperature sensor is installed in the primary combustion chamber, the secondary combustion cylinder, or both of them to control the shutoff valve, or the transport pipe is connected and opened into the thin nozzle. By adopting a method of controlling the shutoff valve with a temperature sensor installed in the next combustion cylinder, it is possible to solve various problems.

The opening forming the other end surface of the secondary combustion cylinder can be constructed to face upward or sideways. A boiler is connected to the opening, or the outer circumference of the primary combustion cylinder is also constructed as a water cylinder, and a pipe is connected to the boiler. can do.

[0008]

In the gasification and combustion furnace apparatus for combustible waste configured as described above, when the raw materials are put into the hopper, they are naturally dropped and deposited on the entire surface of the primary combustion chamber through the grate with a repose angle to a predetermined thickness. , If a raw material feed rack is provided on the lower surface of the hopper, the stacking operation will be performed reliably, and if a blower is driven by igniting by sprinkling a small amount of oil on the upper surface of the stacking, the primary air is supplied from the ventilation port and the flame immediately starts. And the indoor temperature rises, the deposited raw material in the room is actively pyrolyzed to generate volatile gas, and on the other hand, a large amount of secondary air is discharged in a circular shape at high speed from the thin nozzle through the air passage, Volatile gas has a zector effect 2
It is sucked into the secondary combustion cylinder and does not flow out to the hopper side, and the secondary air does not blow off the fire from the primary combustion chamber and flows so as to enclose the volatile gas, while the outer periphery looks like a candle flame. The temperature rises gradually and the combustion temperature rises, and even when the thin nozzle is installed in the spiral direction, if it is facing upward, it works almost the same with the chimney effect, it burns smokeless and odorless with a very small air ratio, low heat quantity Even the raw material reaches a high flame temperature. Usually 1
When an air ratio of about 0.4 is sent from the ventilation port into the secondary combustion chamber, the interior temperature is maintained at about 500 ° C and the raw material is actively pyrolyzed, and an air ratio of 0.4 is reached from the air passage through the nozzle into the secondary combustion cylinder. By sending about 9, the total air ratio can be set to an extremely small value such as about 1.3, and even with a low calorific value biomass raw material, the flame temperature of secondary combustion can exceed 1000 ° C and be treated.

As described above, the biomass raw materials such as rice husks and bark pellets which have relatively small water content and uniform small particles are as described above, but the combustible waste raw materials discharged in the city are non-uniform and include coarse particles, and have a bulk density. Is extremely small, and papers similar to the biomass raw material and heterogeneous synthetic resins may be mixed unspecifically, or high-moisture raw materials such as raw garbage and disposable diapers may be mixed. At that time, if it is configured as described above, coarse raw material is deposited in the primary combustion chamber at a repose angle with a large thickness, and when the raw material feed rack is operated, the raw material is pressed without difficulty and is fed below the repose angle. An appropriate small amount of primary air is ventilated onto the grate at a uniform speed to generate heat of combustion, and the synthetic resin does not generate an abnormally high temperature due to the amount of heat burned by a part of the resin and the rest being pyrolyzed and gasified. The organic raw materials are sequentially dried by the amount of heat supplied, pyrolyzed and burned to carbon content, and they become small lumps by the end of the grate and fall into the crevice and fall through the air gap C.
The remaining carbon content in the raw material is burned out by supplying air to the primary combustion chamber, and the maximum amount of heat is supplied to the primary combustion chamber.
If the raw materials that are liquefied by thermal decomposition such as polyethylene and styrol are mixed at a low rate, the liquefied components will vaporize while adhering to other raw materials and act similarly.If the mixing rate is high, the grate tip It is accumulated from the vent to the bottom of the furnace, but when the bottom of the furnace is configured as a tray and the necessary amount is ventilated from the vent C as described above, a part of it burns and the rest is gasified, and the deposit from the vent B A small amount of additional ventilation near the inner upper surface also burns a portion of the volatile gas to maintain the primary combustion chamber at a predetermined value as described above, and also reliably conveys the fire species from the upper space to the cylindrical opening. Therefore, stable secondary combustion can be secured.

When the chances of using synthetic resins at a high mixing ratio are low, solid fuel such as bark pellets is required from the auxiliary tank into the primary combustion chamber without specially changing the pan and vent C as described above. When the amount is supplied, the liquefied component is absorbed by the solid fuel, and the amount of combustion heat of the solid fuel is vaporized by the normal amount of ventilation from the vent C, so that the liquefaction can be prevented in advance. When the high-moisture raw material is excessively mixed and the average moisture content is excessive, the temperature of the primary combustion chamber is unlikely to rise to a predetermined value due to latent heat of vaporization, so that thermal decomposition and combustion reaction of primary air do not proceed and the primary combustion chamber does not progress. The temperature lowers and synergistically deteriorates, but at that time, when liquid fuel such as waste oil is supplied from the auxiliary tank into the primary combustion chamber, the oils have a high calorific value and a low ignition temperature, so the primary combustion chamber It burns with excess air and raises the room temperature, the reaction is quick, and the excess supply oil is gaseous and goes to the secondary combustion, so there is no danger and the situation can be effectively recovered. In either case, normally, a shutoff valve is controlled by a timer or the like, and bark pellets, waste oil, etc. can be intermittently supplied in a predetermined amount for automation. Even when using normal raw materials, a timer-
By controlling the shutoff valve for a predetermined time and supplying waste oil, etc., almost no smoke is generated.

When the feed materials are not uniform and the mixing ratio of the high-moisture materials is unevenly mixed depending on the time, the temperature sensor installed in the primary combustion chamber detects the temperature drop and shuts off when the raw material moisture is excessive. Valve control is used to intermittently supply a predetermined amount of waste oil and the like to recover the above required value required for thermal decomposition and automatically correct the problem. In addition, the temperature sensor installed in the secondary combustion cylinder detects the presence or absence of secondary combustion, and when it is not igniting, the shut-off valve is opened to supply an appropriate amount of waste oil into the primary combustion chamber, and the flame becomes a thin annular nozzle. When the oil reaches the secondary combustion and ignites to the secondary combustion, or when the oil feed pipe is opened in the nozzle portion in a direction perpendicular to the air flow, the petroleum comes out in the form of spray, so the electric heating coil is energized to directly ignite the secondary combustion A method of automatically maintaining combustion can also be adopted.

Since a flame flow due to gas combustion is ejected from the opening at the tip of the secondary combustion cylinder, it can be used as heat by connecting to an existing boiler or the like. Alternatively, the surroundings of the primary combustion chamber can also be configured as a water cylinder, and piping can be connected to the boiler to improve thermal efficiency.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it produces the effects as described below, and produces combustible waste that is a source of pollution and is in trouble for treatment. It is possible to exert an effect that it is possible to easily and securely treat pollution-free in units of, and to utilize the combustion heat amount as a boiler heat source. This is the result of applying an invention that was put to practical use for rice husks and bark pellets to combustible waste in the urban industry. As a result, a large amount of secondary air was ejected in a ring shape from a thin nozzle to perform primary combustion. The gas is wrapped in and sucked, and the secondary combustion is performed like a candle flame, and the temperature of the primary combustion chamber is maintained at a relatively low uniform temperature of about 500 ° C required for thermal decomposition, while the secondary combustion is performed. In the cylinder, the flame temperature can be adjusted by gas ratio as gas combustion, and generally can be maintained uniformly at about 1000 ° C. The results of the present invention will be described in detail below.

The primary air amount regulated as described above is further subdivided and ventilated from each of the three vent holes divided into ABC, and as a result, generally, a target raw material containing a coarse material and having a low bulk density is provided. Adaptation is possible. The feedstock is gradually ventilated through the grate to promote thermal decomposition and combustion, and it is gradually agglomerated in a piled state and transferred to the furnace bottom, where residual carbon content is burned out in the final step of ventilation at the furnace bottom. Finish to a white ash. Further, the primary combustion chamber is maintained at a required temperature by ventilating near the upper surface of the deposition layer, which has become small and has increased in temperature, and the flame flow can be connected to the upper thin nozzle portion to ensure stable secondary combustion. Therefore, even in a use example in which synthetic resins that easily generate an abnormally high temperature are mixed, the primary combustion chamber is maintained at a relatively low uniform temperature, and the inner wall is thinly protected by soot or tar. It can be said that it is a tremendous improvement compared to the conventional technology of incinerators that were made of ordinary iron plates and can withstand heat, and were constructed of refractory bricks. In addition, in the above-mentioned final process, since it is burnt out to a uniform high temperature to prevent uneven burning, for example, pathogenic fungi and the like in medical waste can be surely extinguished, and safety can be easily ensured.

In the combustible waste, there is a chance of mixing high-moisture garbage and disposable diapers, and moreover, it is mixed at a high rate evenly depending on the time.
By supplying the liquid fuel from the auxiliary tank as detected by the temperature sensor, the functions can be promptly and safely updated accurately, and automatic processing can be performed, making a great leap from the technological stage for biomass such as rice husks and bark. There is no need for an expensive oil combustion device, waste oil can be used easily, and there is an effect that waste oil, which is waste, can be utilized.

The proportion of synthetic resins in municipal combustible wastes is increasing year by year, and it is the current situation that synthetic resins are almost all depending on the generation site. Attempting to recycle them is also important, but in reality it is difficult to be economical and a simple incineration method is desired. The present invention
It can respond to the demand with a simple device. What's more, it can handle any mixing ratio of synthetic resins,
It can also be applied when the mixing ratio changes with time.

At present, combustible waste is incinerated.
It is a sad situation from the viewpoint of energy utilization. Some large incinerators use the boiler as a heat source, but it is difficult to utilize residual hot water because the waste treatment plant is located in a remote area. On the other hand, the heat utilization of biomass resources such as rice husks and bark is difficult to spread due to the idea only under the current situation where oil is cheap and simple. For combustible waste in the urban industry targeted by the present invention, in the present situation where self-responsibility treatment of the generation site is an issue, simple treatment in each generation site is desired, and the present invention meets the demand. Smokeless and odorless high-temperature flame flow should naturally be utilized as a boiler-heat source, and the result of utilization is a slight reduction in oil costs, leading to corporate profits and fossil fuel savings. It will help to protect the global environment, and it is expected that resource utilization will eventually be realized and spread.
