Description

Complex Incinerator

The present invention relates to a complex incineration apparatus that can classify and incinerate general waste or specific waste.

Incinerators are divided into two types according to the waste incineration method: direct combustion incinerators and dry distillation incinerators.

Direct incinerators are used to incinerate waste by supplying enough heat and air to burn the wastes in the furnace, and burn them.

However, when incineration of waste by direct combustion incinerator, the surface is burned, so it is difficult to completely burn the waste, so when the waste is incinerated, a lot of smoke, odor and dust are generated. It is becoming.

On the other hand, in order to solve the problems of the direct combustion incinerator, in recent years, the distillation incinerator which supplies the heat and air enough to be combusted without burning the waste in the furnace does not cause a flame, is widely used.

Incineration by dry distillation incinerator is combustible gasification of the waste and combustion of the combustible gas in the combustion chamber, so that the waste can be completely burned, and secondary pollution such as soot, odor and dust does not occur.

Therefore, the distillation incinerator can not only incinerate waste without generating soot, odor, dust, etc., but also utilizes a lot of waste heat generated during incineration to use hot water and electric power.

However, since the conventional dry ash incinerator is not equipped with a fire ash discharge device, the waste is introduced into the incinerator at the beginning of operation, and after the waste incinerator is incinerated, the operation is continued until the dry incinerator is naturally cooled. After the incinerator has been cooled down, the ash in the furnace is discharged and transported by manpower, and then the waste is put into manpower into the dry-fired incinerator. There was a problem that could not be achieved.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a complex incineration apparatus which can burn waste without auxiliary fuel by its own heat after igniting waste containing a large amount of water. .

Another object of the present invention is to provide a complex incineration apparatus capable of classifying and combusting waste synthetic polymer compound-based waste industrial waste and household waste.

In order to achieve the above object, the complex incineration apparatus according to the present invention comprises a dry matter for burning waste synthetic polymer compound waste at low temperature, an input means for injecting waste synthetic polymer cargo waste into the dry matter, and a primary of the dry matter breaker. A cooling water tank for storing the cooling water for cooling the combustion air supply means, a cooling water pump for pumping the cooling water stored in the cooling water tank and supplying the cooling air to the primary combustion air supply means of the dryer, and the distillate gas discharged from the dryer. Drying gas generated between the grate incinerator which generates flame by the third ignition burner and mixes and combusts it with domestic waste and industrial waste, and the inlet of the distillation gas of the drier and the inlet of the grate incinerator. It characterized in that the valve for controlling the discharge and blocking of.

Hereinafter, the operation and effects of the composite incineration apparatus according to the embodiment of the present invention thus constructed will be described.

When the waste for incineration is introduced into the incineration container 204 through the hopper 202 of the waste input means 200, the piston (not shown) in the cylinder 206 is moved forward by the hydraulic action, which is not shown. Waste for incineration is introduced into the distillation apparatus 100 through the guide pipe and accumulated on the cooling water supply pipes 146a and 146b and the nozzle 142. In this way, if the waste accumulates in the dryer (), the amount of waste is stopped, and then a plurality of valves 144 provided between the respective air tanks l45 and the air supply pipe 143 are opened. The coolant pimp 139 and the first air supply fan 141 are operated.

At this time, since combustion air is supplied to each air supply pipe 143, combustion air is supplied from a plurality of nozzles 142 provided at regular intervals in the air supply pipe 143, and the air supply pipe 143 Cooling water is circulated through the cooling water supply pipes 146a and 146b that are externally wounded by the "

The cooling water supply pipes 146a and 146b generally divide the planar area of the distillation machine 100 into two, and the cooling water is supplied to the central cooling water supply pipes 146a and 146b, and then flow to the refractory brick layer 106 side of the distillation machine 100. Therefore, the cooling efficiency is good and there is no fear that the nozzle 142 may be detached from the air supply pipe 143.

Next, the flame is ignited by the first and second ignition burners 109a and 109b through the flame inlets 101a and 101b through the flame inlets 101a and 101b to the incineration wastes of the cooling water supply pipes 146a and 146b and the nozzle 142.

When the incineration waste is incinerated, the dry gas generated in the dry dryer 100 begins to be introduced into the inlet 302 of the grate incinerator 300 through the dry gas discharge port 130 and the valve 355. The air is supplied to the air inlet 302 by driving the air supply chamber 304, and at the same time, when the diesel oil in the diesel tank 306 is burned by the third ignition burner 308, a flame is generated. By blowing the flame into the inlet 302, the dry gas discharged from the dry gas discharge port 130 of the dry dryer 100 is burned again to form a flame in the inlet 302 of the grate incinerator 300. .

Next, at the same time through the inlet 310 of the grate incinerator 300 to the first loading stage 332 of the primary combustion chamber 330 formed in the grate incinerator 300, the domestic waste and industrial waste, The first auxiliary burner 312 is operated in the primary combustion chamber 330 to inject flames, and the third air supply fan 349 is operated to drive the third ignition burner 308 while supplying combustion air. When the flame is generated by the combustion of the dry gas introduced through the inlet 302 of the grate incinerator 300, the combustion and the industrial waste introduced through the inlet 310 and the industrial waste are mixed. do.

However, in the primary combustion chamber 330 of the grate incinerator 300 of the present invention, the domestic waste and the industrial waste introduced from the inlet 310 are sequentially in accordance with the operation of the first to fifth hydraulic cylinders 341-345. Since it moves from the 1st loading stand to the 5th loading stand 332-336, the combustion air is supplied sufficiently and the combustion time can be shortened.

In other words, since the first to fifth mounting tables 332 to 336 are formed in a stepped manner, the first to fifth mounting tables 332 to 336 are formed in a stepped manner, so that the first to fifth mounting tables 332 to 336 are sufficiently supplied to the domestic waste and the industrial waste to incinerate the combustion air supplied by the third air supply fan 349. Therefore, it can be incinerated quickly.

In addition, the unburned incinerations and ashes of the first to fifth mounting tables 332 to 336 are installed below the fifth mounting table 336 by the operation of the fifth hydraulic cylinder 345. Since it falls on the grate 347 of the ash combustion chamber 331, the incineration and ash unburned in the first to fifth mounting tables 332 to 336 are again on the grate 347 of the ash combustion chamber 331. Is burned.

The ash generated by the combustion is discharged from the ash outlet 35 () by the operation of the screw conveyor 351 is conveyed to a specific position by the conveyor 370.

On the other hand, unburned dry gas introduced through the inlet 302 and unburned dry gas generated by the combustion of domestic waste and industrial waste in the primary combustion chamber 330 to the secondary combustion chamber 316 The waste oil raised and discharged from the waste oil storage tank 318 is completely burned again with the flame generated by burning the second auxiliary burner 320.

In the secondary combustion chamber 316, dry gas is heated and burned at 800-1500 ° C., so odors generated during combustion or dioxins harmful to a human body are decomposed by heat and vaporized through a gas outlet 324 (not shown). And are filtered again by steam and then discharged into a heat exchange chamber or atmosphere, not shown.

Therefore, the complex incineration apparatus of the present invention ignites the flame by the heating burners 109a and 109b to the waste containing a large amount of water injected onto the cooling water supply pipes 146a and 146b and the nozzles 142 in the drier 100. After the combustion, the waste can be completely burned without auxiliary fuel by its own heat, and the waste synthetic polymer compound-based waste is incinerated in the distillation unit 100, and the industrial waste and household waste are burned in the grate incinerator 300. Therefore, the waste synthetic polymer compound waste, industrial waste and domestic waste can be classified and completely combusted.

As described above, according to the complex incineration apparatus of the present invention, a dry distillation unit for burning the waste synthetic polymer cargo waste at low temperature, an input means for introducing the waste synthetic polymer cargo waste into the dry matter, and a primary of the dry distillation unit A cooling water tank for storing the cooling water for cooling the combustion air supply means, a cooling water pump for pumping the cooling water stored in the cooling water tank and supplying the cooling air to the primary combustion air supply means of the dryer, and the distillate gas discharged from the dryer. Drying gas generated between the grate incinerator which generates flame by the third ignition burner and mixes and burns it with the domestic waste and the industrial waste, and the inlet of the dry gas discharge and the grate incinerator of the drier. Cooling water supply pipe and nozzle in the dryer After the spark ignition by the first and second ignition burner the wastes containing a large amount of water is put in there is an effect that can complete combustion of wastes without secondary fuel by heat itself.

In addition, since the waste polymer waste polymer is incinerated in a dry cell, industrial waste and household waste are combusted in a grate incinerator, so the waste synthetic polymer compound waste, industrial waste and household waste can be classified and completely combusted. It has an outstanding effect.
