Description

Waste Incinerator {TRAH BURNER}

The present invention relates to an improved waste incineration apparatus that incinerates (burns) waste tires and various wastes such as high value compounds such as waste rubber and waste synthetic resins and hospital extracts.

In more detail, the primary combustion chamber of the primary chamber installed at the lower side and the secondary combustion chamber of the secondary chamber installed at the upper side are communicated by gas passages, and the waste is introduced into the primary combustion chamber to the primary burner. By primary combustion, and gas generated from the primary combustion chamber (incomplete combustion gas) is burned completely by the secondary burner after the secondary incineration of the gas flowing into the secondary combustion chamber through the gas passage. The gas generated in the primary combustion chamber by the injection force of the air injected from the air injection ejector to the secondary combustion chamber by installing an air injection ejector inside the gas passage communicating the primary combustion chamber and the secondary combustion chamber ( Incomplete combustion gas) can be quickly moved to the secondary combustion chamber and burned in the secondary combustion chamber to improve the combustion efficiency, and the secondary combustion chamber is equipped with a separate waste heat boiler for secondary combustion. It will provide value to a waste incineration plant using the waste heat discharged from the loss to be able to operate the boiler.

In recent years, various kinds of waste such as household waste and industrial waste increase, which pollutes the environment (land and air).

In general, various wastes are incinerated, and since wastes contain a large amount of water and carbon, there is a problem of incomplete combustion due to thermoplastic or thermosetting properties when incinerated.

Figure 1 shows a conventional waste incineration apparatus (1), which is commonly used, the input door (2-1) is formed on the side and the gas discharge pipe (2-2) formed on the upper end of the incinerator (2) Air inlet (3) is mounted, the lower end of the incinerator (2) is equipped with a burner (7) supplied with fuel from the fuel tank (8), the air supply pipe (5) connected to the blower (4) is air Branched to the distribution supply pipes 6-1 and 6-2, it is connected to the burner 7 and the air blowing device 3.

By operating the blower 4 to supply the air to the burner 7 and the air inlet 3, the burner 7 is operated, while the burner 7 is operated, the waste is incinerated through the inlet 2-1. It is injected into (2) and incinerated, and the combustion gas which is generated when the waste is incinerated is discharged to the atmosphere through the gas discharge pipe (2-2).

The conventional waste incineration apparatus 1 constructed and used as described above is incinerated only once in an incinerator 2 formed solely, and thus its incineration capacity is low, especially when incineration of general wastes when incineration of a polymer compound. Likewise, if the same amount of air is supplied, the combustion of the fuel occurs rapidly before the oxygen is completely diffused, and the smoke is extremely generated. As a result, the fuel is consumed excessively and the waste and waste gas cannot be completely burned. .

Therefore, in order to purify the combustion gas that is incompletely burned, there is a necessity to install an expensive wet scrubber or an electrostatic precipitator.

In order to solve the above problems, I proposed (design) a waste incineration apparatus 1-1, which is Utility Model Registration No. 20-136768, as illustrated in FIG.

In the waste incineration apparatus 1-1 illustrated in FIG. 2, the secondary burner 21 is disposed on the upper side of the primary chamber 15 in which the primary burner 15 is mounted and the inlet 11 and the sweeping tool 12 are formed. Is installed and the secondary chamber 20 having the flue 22 installed at the top thereof is supported by the support 23 to be installed, but the primary combustion chamber 10-1 of the primary chamber 15 is installed by the gas passage 16. ) And the secondary combustion chamber 20-1 of the secondary chamber 20 communicate with each other, and the primary chamber 10 forms an air inlet chamber 13 below the air distribution plate 14 at an inner lower end thereof. The air of the blower 25 can be supplied by the primary air supply pipe 13, and the secondary air supply pipe 27 connected to the blower 25 is installed outside the secondary chamber 20 and the secondary air is provided. At the upper end of the supply pipe 27, a plurality of air injection pipes 27-1 are mounted to be inserted into the secondary chamber 20.

In the conventional waste incineration apparatus 1-1 formed as described above, the waste is introduced into the primary combustion chamber 10-1 through the inlet 11 of the primary chamber 10 while the primary burner 15 is operated. While injecting and burning, the blower 25 is operated to incinerate the air through the air inlet chamber 13 while supplying air to the inside of the primary combustion chamber 10-1, and waste in the primary combustion chamber 10-1. The gas generated while incinerated is introduced into the secondary combustion chamber 20-1 through the gas passage 16, and a blower is provided in the primary combustion gas introduced into the secondary combustion chamber 20-1 through the gas passage 16. The oxygen supplied from 25) is injected into the inside of the secondary combustion chamber 20-1 through the air injection pipe 27-1 to be secondly burned by the secondary burner 21 and then discharged through the flue 22. It is.

However, in the conventional waste incineration apparatus 1-1, which is constructed and operated as described above, the gas generated while the waste is incinerated in the primary combustion chamber 10-1 is simply raised through the gas passage 16 so that 2 Since the inflow capacity of the gas is lowered due to the inflow of the combustion chamber 20-1, the inflow capacity of the gas is reduced from the primary combustion chamber 10-1 to the secondary combustion chamber 20-1. Since the gas is stagnated in the primary combustion chamber 10-1, the incineration capacity of the waste is also reduced, and the gas of the primary combustion chamber 10-1 does not flow smoothly into the secondary combustion chamber 20-1. In addition, the secondary combustion capacity is not only degraded, but also causes the air to be discharged to the outside in an incomplete combustion state that does not completely burn the gas to contaminate the atmosphere.

In addition, the conventional waste incineration apparatus 1-1 discharges (discharges) the hot air generated when burning wastes to the outside, so there is a closed end that does not utilize the heat generated by incineration at all.

The present invention seeks to provide an improved waste incinerator that combusts various wastes in two stages.

According to the present invention, the primary combustion chamber of the primary chamber provided at the lower side and the secondary combustion chamber of the secondary chamber provided at the upper side are communicated by the gas passage, and the primary burner is introduced by injecting waste into the primary combustion chamber. Incineration, and the gas (incomplete combustion gas) generated in the primary combustion chamber is secondary burned by the secondary burner to completely burn the gas flowing into the secondary combustion chamber through the gas passage, and then the complete combustion gas is discharged through the flue. But let's

An air injection ejector is installed inside the gas passage that communicates the primary combustion chamber with the secondary combustion chamber so that gas generated from the primary combustion chamber (incomplete combustion gas) is discharged by the injection force of the air injected from the air injection ejector into the secondary combustion chamber. The purpose of the present invention is to provide a waste incineration device that can be quickly moved to the secondary combustion chamber, and the secondary combustion chamber is equipped with a separate waste heat boiler so that the waste heat discharged from the secondary combustion chamber can be reused.

Another object of the present invention, the gas generated in the primary combustion chamber (incomplete combustion gas) by the discharge force of the air injected through the air injection ejector installed in the gas passage to guide the secondary combustion chamber to be introduced quickly In addition, the secondary combustion of the incomplete combustion gas flowing into the secondary combustion chamber to improve the combustion efficiency and to provide a waste incineration apparatus that can prevent the pollution of the atmosphere by exhausting the complete combustion gas.
