Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator capable of incinerating undesired incineration of waste liquid such as waste oil, waste water, and waste solvent.

[0002]

2. Description of the Related Art In recent years, in the technical field of waste incineration treatment, so-called closed system treatment has been performed in which incineration ash is generated at each place where dust is generated in order to preserve the living environment. At the time of incineration of this refuse, there is a possibility that incineration exhaust gas containing dust, harmful gas, etc. may be generated. Therefore, this incineration of waste causes new air pollution and causes so-called secondary pollution. In order to avoid this, in this type of waste incineration processing device, it is necessary to completely burn the waste into a smokeless state. Therefore, various devises have been made to the structure of the incinerator, and various incinerators have been developed and put into practical use.

For example, the incinerator described in Japanese Examined Patent Publication No. 61-38370 is an incinerator in which a chimney communicating with the ceiling of a secondary combustion chamber is erected, and a flue is directed toward an end wall provided with a combustion burner. Inclined, the combustion burner is inclined downward at a small angle with respect to the axis of the secondary combustion furnace, and a grate formed to have a medium height is installed in the primary combustion chamber on the side opposite to the flue,
An ignition burner is provided on the peripheral wall inwardly surrounding the grate. With this configuration, an incineration process that promotes thermal decomposition is performed.

In Japanese Utility Model Publication No. 60-34901, a combustion heating chamber is provided above the primary combustion chamber provided with an air compressor, which extends outward and has passages formed only above and below the central portion. A blower was attached above the center of the heating chamber 2
It describes an incinerator with a secondary combustion chamber. In a conventional incinerator, for example, when tires are burned, incomplete combustion occurs to generate a large amount of black smoke. This incinerator has a simple structure by performing two-stage combustion with the above-described structure. This makes it possible to completely burn the solid fuel.

In addition to the above-mentioned solid waste, the liquid remaining after the reaction product is reacted with a solvent or an additive to produce a target product is also called industrial waste, and requires an appropriate waste treatment. Such liquid waste uses water in the production process, is hydrated, and is discharged. For this reason, the waste liquid is discharged without decomposing the organic matter, which causes environmental damage to the nature of the discharge destination. From the standpoint of nature conservation, it is most desired to develop equipment for detoxifying organic substances in wastewater and wastewater countermeasures.

[0006]

By the way, in each of the above-mentioned incinerators, solid or high-moisture sludge or the like is the main object to be incinerated. However, as described above, some industrial wastes are liquid waste liquids, and such waste liquids cannot be incinerated sufficiently in the incinerator as described above. In addition, even if waste liquid is incinerated, it is not possible to perform highly efficient incineration processing, so there is a possibility that, for example, incomplete combustion will cause harmful gases, dust, etc. to be scattered and cause new environmental pollution of the atmosphere. There is. Moreover, in order to completely burn the waste liquid, a large amount of fuel for incineration is required, and highly efficient incineration cannot be performed, resulting in a decrease in economic efficiency.

Therefore, in view of the above situation, the present invention is designed to be installed in a space-saving manner while maintaining highly efficient combustion even if the object to be incinerated is a liquid waste liquid, and is highly economical and safe. The purpose is to provide an incinerator.

[0008]

And a combustion object through a conduit to spray the vaporization chamber of the incinerator body into a spray supply unit, a combustion stabilization unit disposed at the center of the secondary combustion chamber, A chimney connected to the flue provided in the incinerator body, and a connection between the flue and the chimney And a pair of second combustion burners provided on the side of the secondary combustion chamber. The flame is injected in the tangential direction of the substantially circular inner wall surface of the secondary combustion chamber so that whirlwind is formed in the combustion chamber.
The combustion stabilizing means are disposed at opposite positions of the next combustion chamber, and the combustion stabilizing means surrounds the communicating portion so as to form a hollow portion in the central portion, and a plurality of distractions are provided upright at a predetermined interval. A plurality of distractions are provided on an upper end side of the distraction to cover the hollow portion, and the plurality of distractions are provided from an outer peripheral portion in contact with a flame injected from the second combustion burner to the hollow portion. A flat fan shape gradually thinned toward the facing inner peripheral portion is formed into a substantially fan shape, and a gap having a substantially equal width is formed between the inner peripheral portion and the outer peripheral portion between adjacent distractions. Is.

Here, since the incinerator for burning the waste liquid as the combustion object is operated unattended, a fuel tank for storing the fuel supplied to the first combustion burner and the second combustion burner is provided. A fuel supply pump for supplying fuel from the fuel tank to the first combustion burner and the second combustion burner arranged in the incinerator body, and a combustion object storage tank for storing the combustion object.

A control means for controlling the combustion state is provided by this control means.

[0010]

In the incinerator according to the present invention, the liquid combustion object spray-supplied into the evaporation chamber of the incinerator body through the spray supply means falls into the primary combustion chamber and is distributed to the primary combustion chamber. It is burned by the installed first burner. When the combustion is started, the liquid combustion target object that is spray-supplied into the evaporation chamber is decomposed, evaporated and burned in the evaporation chamber. The combustion object that has not been completely combusted in the primary combustion chamber and the evaporation chamber rises in the evaporation chamber due to the ascending air current generated in the evaporation chamber, and passes through the communication section and the combustion stabilizing means.
It is sent to the next combustion chamber. The combustion object sent to the secondary combustion chamber is decomposed into a minute size by passing through the combustion stabilizing means, and is combusted by the second combustion burner provided in the secondary combustion chamber.

The secondary combustion chamber 17 so that flames are respectively injected toward
Are arranged at positions opposite to each other.

The primary oil burners 12 provided in the primary combustion chamber 15 may have a structure in which two primary oil burners 12 are provided at positions opposite to each other for efficient swirl combustion.

A stabilizer 21, which is a combustion stabilizing means for stabilizing combustion, is disposed in the center of the secondary combustion chamber 17 in the secondary combustion chamber 17. As shown in FIG. 2, the stabilizer 21 has a hollow portion 21c formed in the center thereof, and surrounds a communication portion 17a for communicating the evaporation chamber 16 and the secondary combustion chamber 17 so as to form a cylindrical shape as a whole. It is composed of a plurality of distractions 21a which are provided upright with a predetermined space therebetween, and a lid 21b which is disposed on the upper end side of these distractions 21a and covers the hollow portion 21c. Then, the plurality of distractions 21a forming the stabilizer 21 are
The inner peripheral portion 23 facing the hollow portion 21c from the outer peripheral portion 22 in contact with the flame injected from the secondary oil burners 13 and 14.
The planar shape that is gradually thinned toward is formed into a substantially fan shape. Each distraction 21a is formed with a gap 21d having a substantially equal width from the inner peripheral portion 23 to the outer peripheral portion 22 between the distractions 21a adjacent to each other. The gap 21d is for passing the waste liquid mist supplied from the evaporation chamber 16 into the secondary combustion chamber 17. The distraction 21a is
The mist-like waste liquid mist supplied from the evaporation chamber 16 is further decomposed into a minute size to assist evaporation, and the flow of the mist-like waste liquid mist supplied is changed to two secondary oil burners 13.
It has a function as a member for guiding so as to blow out in the same direction as the direction of the whirlwind formed by the shear flow of flame by 14.

The distraction 21a is a step portion 16b formed on the secondary combustion chamber 17 side of a portion projecting inward of the secondary combustion chamber 17 so as to form a communication portion 17a having a reduced diameter. It is erected on the top.

The distraction 21a constituting the stabilizer 21 surrounds the communicating portion 17a so as to form the hollow portion 21c so that the atomized waste liquid can be supplied from the evaporation chamber 16 described above. Are erected at eight locations to form a cylindrical body. The durability of the plurality of distractions 21a is improved by making the outer peripheral portion 22 in contact with the flames injected from the secondary oil burners 13 and 14 thicker than the inner peripheral portion 23. Further, the distraction 21a has a fan-shaped planar shape, and a gap 21d having a substantially equal width from the inner peripheral portion 23 to the outer peripheral portion 22 is formed between the distractions 21a adjacent to each other.
By forming the, the mist-like waste liquid mist supplied from the evaporation chamber 16 can be uniformly blown into the secondary combustion chamber 17.

Since the contact surface between the distraction 21a and the lid portion 21b of the stabilizer 21, which will be described later, can be wide, the distraction 21a can be installed in a stable state with the lid portion 21b.

The lid 21b of the stabilizer 21 is also provided.
Covers the upper end side of the distraction 21a, so that all of the mist-like waste liquid mist is distracted by the distraction 21a.
It is designed to flow into the gap 21d between a. further,
The stabilizer 21 has a cylindrical shape as a whole as shown in FIG. 2 in order to prevent incomplete combustion. Also,
The lid portion 21b that covers the upper end of the distraction 21a is also formed in a circular shape corresponding to the outer peripheral shape of the distraction 21a. Since the stabilizer 21 is formed in a cylindrical shape and the upper end thereof is covered with the circular lid portion 21b as described above, the atomized waste liquid can be uniformly supplied in each direction in the secondary combustion chamber 17. The temperature and pressure in the secondary combustion chamber 17 can be averaged by supplying the object to be incinerated uniformly. This stabilizer 21
For example, it is formed of carborundum or a material having a fire resistance equal to or higher than that of carborundum.

By disposing the distraction 21a of the stabilizer 21 and the lid 21b of the stabilizer 21 in this way, the flow of the waste liquid mist in the secondary combustion chamber 17 is arranged at two positions that form a shear. The secondary oil burners 13 and 14 can stably flow out in the same direction as the direction of the whirlwind. A swirl is formed in the secondary combustion chamber 17 by the flow of the waste liquid mist and the flame, and swirl 2 for complete combustion over time.
Next combustion is performed.

The waste liquid and the fuel are supplied through strainers 36 to 40 for filtering large dust contained in the waste liquid and dust contained in the fuel supplied to each combustion chamber.

By the way, when an exhaust chimney is erected above the secondary combustion chamber 17 located on the upper side of the incinerator body 11, the load resistance is suppressed, so that the exhaust gas is efficiently discharged. Is well known. However, in the combustion gas in the secondary combustion chamber 17, which has the highest temperature in the combustion furnace main body 11, there is a high possibility that a large amount of air pollutants will be generated due to this high temperature. It is a big problem that even the smokeless and odorless gas emits the combustion gas containing the air pollutants as it is into the atmosphere. In addition, it is desirable to increase the size of the chimney in order to perform efficient exhaust, but the secondary combustion chamber 1
When a large chimney for exhaust is erected on the upper side of 7, it becomes necessary to provide a complicated support structure material on the secondary combustion chamber 17 to support the large chimney. The standing of this large chimney is a problem in view of complicating the structure of the combustion furnace body 11 and the risk of collapse.

Therefore, in order to efficiently discharge the burned gas, a flue 18 extending substantially horizontally from the ceiling constituting the upper end of the secondary combustion chamber 17 is provided, and the flue 18 of the incinerator body 11 is provided. It is connected to a chimney 41 standing upright at a side position. By connecting to the chimney 41, which is installed separately from the incinerator body 11 via the flue 18, it is possible to avoid standing of a large chimney that is integral with the incinerator body 11, and at the same time eliminate the above problems. can do. Further, an ejector nozzle 42, which is an air ejection portion for ejecting air supplied from an ejector fan 43, which is an air supply means provided outside the combustion furnace main body 11, is provided near the connection between the flue 18 and the chimney 41. No, by supplying air to this portion, the temperature of the exhaust gas discharged from the flue 18 into the chimney 41 is lowered. By cooling this exhaust gas, air pollutants and the like can be made into other compounds and made into safe and clean exhaust gas, which can be exhausted. The inner walls of these chimneys 18, 41 are lined with refractory material.

Further, by causing the ejector nozzle 42, which is an air jet, to face the connection portion between the flue 18 and the chimney 41, the combustion gas in the secondary combustion chamber 17 is sucked through the flue 18. It is possible to bring the secondary combustion chamber 17 into a depressurized state. As a result, the secondary combustion chamber 17 is decompressed from the primary combustion chamber 15 and the evaporation chamber 16, and the unburned combustion target is efficiently raised from the primary combustion chamber 15 and the evaporation chamber 16 to the secondary combustion chamber 17. Can burn, secondary combustion chamber 17
It is possible to realize reliable combustion of the unburned combustion target.

Next, the basic operation of the incinerator 10 according to the present invention and the unmanned operation of the incinerator 10 will be described with reference to FIG. In the incinerator 10, all parts are controlled by the above-mentioned automatic control panel 30. In order to perform operation control according to the temperature and pressure inside each of the incinerator main body 11, for example, a temperature sensor such as a thermocouple or a pressure sensor is provided to detect the inside of each inside of the incinerator main body 11. The automatic control panel 30 is supplied with signals from temperature adjustment alarm devices 45 and 46 that issue an alarm according to the temperature detected by the temperature sensor and a pressure adjustment alarm device 47 that issues an alarm according to the pressure value detected by the pressure sensor. Has been done.

The automatic control panel 30 controls the amount of fuel supplied to the combustion chambers 15 and 17 by the pump 32 while controlling the operation of each oil burner via the temperature adjustment alarm devices 45 and 46, for example. There is. Also, the waste liquid is used in each combustion chamber 1
The waste liquid supply pump 34, the compressor 35, and the pressure adjustment alarm device 4 in order to perform the supply according to the conditions of 5 and 17.
The three-way switching valve 48 is controlled via 7 and supplied. By the switching control of the three-way switching valve 48, the supplied waste liquid and the high-pressure air supplied from the compressor 35 are sequentially supplied to the conduit 19, and the pressurized waste liquid is sprayed from the spray nozzle 20. This pressurized spray improves the contact efficiency between the liquid and the gas, and the amount of the auxiliary combustion material can be reduced.

In order to ensure safety, the pressure switch 4
9 is disposed between the pump 34 for supplying the waste liquid and the conduit 19 of the three-way switching valve 48, and if an abnormality is detected, this pressure switch 49 is operated by the control signal supplied from the automatic control panel 30. Stop the supply of.

In this way, each part in the incinerator body 11 is constantly controlled. The supplied waste liquid is used in the evaporation chamber 1
The inside of 6 is sprayed downward with pressure. This pressure spray forms waste liquid mist of various sizes. Of the various kinds of waste liquid mist thus formed, a waste liquid mist A having a large size and a large specific gravity and a waste liquid mist B having a small size and a light specific gravity are mainly divided.

The waste liquid mist A is decomposed, evaporated and burned in the evaporation chamber 16 while descending. In order to evaporate the water during this descent, the spray nozzle 2 in the flue 16
The distance between the installation position of 0 and the flue to the primary combustion chamber 15 is required. This distance is also taken into consideration in the incinerator 10 according to the present invention. In the present embodiment, the incinerator body 11
The waste liquid, which is a combustion product, is sprayed from a height of about ⅔ from the lowermost portion 15a of the
The so-called destructive area
It is a zone. The distraction 44 having a porous structure formed in the lower portion 44a of the distractive zone.
Are installed. Distraction 44 is the evaporation chamber 1
While preventing, for example, organic substances contained in the waste liquid mist A supplied from inside 6 directly falling into the primary combustion chamber 15, the organic substances and water in the waste liquid mist A are destroyed and separated.

In the waste liquid mist A, a relatively large organic matter is incinerated in the distraction 44, and water is evaporated and finely divided organic matter is burned in the primary combustion chamber 15. The inside of the primary combustion chamber 15 is constantly about 900-
It has reached a temperature of 1100 ° C. This primary combustion chamber 15
The combustion speed of is lower than that in the secondary combustion chamber 17. The waste liquid mist A has a size considerably larger than that of the waste liquid mist B finely broken by hitting a distraction 21a described later. Therefore, the waste liquid mist A having a large size is slowly decomposed and the combustion speed of the primary combustion chamber 15 is also slow.

The waste liquid mist B is separated and evaporated by pressure spraying, and the oily component slowly rises upward through the evaporation chamber 16. The ascending process in the evaporation chamber 16 is mainly a process called swirl evaporation combustion. The steady temperature in the upper part of the evaporation chamber 16 is
The temperature is 500 to 650 ° C.

In the above-mentioned structure, since the air is blown to the chimney 41 to forcibly discharge the gas,
The pressure inside the secondary combustion chamber 17 is lower than that in the primary combustion chamber 15, and the pressure is reduced. Therefore, the waste liquid mist B is
It is smoothly supplied into the secondary combustion chamber 17. Further, at this time, even if a large-sized waste liquid mist such as the waste liquid mist A is supplied, the waste liquid mist collides with the plurality of distractions 21a formed in the stabilizer 21 and is mainly decomposed into water and an oil component. To help evaporation.

Further, since the secondary combustion chamber 17 uses swirl combustion in which two secondary oil burners 13 and 14 are arranged at positions facing each other and the combustion is performed with a long residence time, complete combustion is achieved. Can be promoted. Thus, the temperature of the furnace in the incinerator body 11 reaches the maximum temperature due to the decomposition of the waste liquid mist and the swirling combustion in the secondary combustion chamber 17. By the swirling secondary combustion, the waste liquid mist or the waste liquid mist B having a low specific gravity of oily components is completely burned to become smokeless and odorless safe clean exhaust gas. The temperature of the exhaust gas finally discharged from the chimney 41 is set to about 300 ° C and discharged.

Further, since the inside of the furnace is always kept at a negative pressure, safety such as leakage of high temperature gas can be improved.

The flue 18 on the side of the secondary combustion chamber 17 has a high temperature of about 800 ° C. It is also possible to recover this exhaust heat and generate hot water / steam for use.

By thus performing the two-stage combustion,
For all waste liquids, it is possible to completely incinerate organic substances and the like contained in the waste liquid into smokeless and odorless exhaust gas to render them harmless. Further, the highly efficient incineration process and automatic control enable unmanned operation for 24 hours, which is very economical because it saves costs and requires a small amount of auxiliary combustion material.

[0041]

As is clear from the above description, even if the object to be incinerated is a liquid waste liquid, highly efficient combustion can be maintained and complete combustion can be achieved, and the atmospheric environment can be preserved. it can.

Further, by disposing an air spouting portion for spouting the air supplied from the air supply means by facing the vicinity of the connection with the chimney connected to the flue provided in the incinerator main body, The secondary combustion chamber is decompressed from the primary combustion chamber, a smooth ascending supply of the unburned combustion target to the secondary combustion chamber is realized, and the unburned combustion target on the primary combustion chamber side is completely burned. It can be emitted from the chimney as a safe and clean exhaust gas that is smokeless and odorless.

Further, the introduction of the automatic control device enables the unmanned operation for 24 hours and the highly efficient combustion of the incinerator makes it possible to enhance the economic efficiency.

Further, the rational design allows the incinerator to maintain a high level of safety and allows the incinerator to be installed in a small space.
