Abstract

The invention relates to an incinerator device capable of reducing nitrogen oxides, which mainly comprises a hearth, an air duct, a furnace end and a surrounding shield which are combined, and gas to be treated can be conveyed to an air outlet through the air duct. The to-be-treated gas flows out to the front end of a combustion flame generated by the furnace end through a gas channel reserved between the air outlet and the surrounding shield, so that the destroying efficiency of volatile compounds contained in the to-be-treated gas can be improved, and the combustion-supporting gas entering from a combustion-supporting gas inlet of the furnace end is improved by 20%-30% of the combustion equivalent; and the excessive combustion-supporting gas can enable the temperature of combustion flames generated by the furnace end to be reduced, so that after the to-be-treated gas (such as mixed gas containing more than one volatile organic compound and air) passes through the generated combustion flames, the generation of nitrogen oxides can be reduced, and the effect of reducing the generation of the nitrogen oxides is achieved.

Description

Technical Field

[0001] The present invention relates to an incinerator device with reduced nitrogen oxides, particularly an incinerator device or similar equipment applicable to the semiconductor industry, optoelectronic industry, or chemical-related industries, which can reduce the generation of nitrogen oxides when the gas to be treated (such as a mixture of one or more volatile organic compounds and air) passes through the generated combustion flame, thereby having the efficacy of reducing the generation of nitrogen oxides. Background Art

[0002] Currently, volatile organic gases (VOCs) are generated during the manufacturing processes of the semiconductor industry or optoelectronic industry. The volatile organic gases (VOCs) contain compounds such as nitrogen oxides (NOx) and sulfur oxides (SOx). Nitrogen oxides (NOx), sulfur oxides (SOx), and other compounds are one of the important causes of photochemical smog, acid rain, and human respiratory diseases.

[0003] Currently, in the industry, for volatile organic gases (VOCs), the general practice is to first perform adsorption and desorption processes through a rotating wheel, and then send the concentrated and desorbed gas into the incinerator for high-temperature decomposition. However, during the high-temperature decomposition process, the generation of nitrogen oxides (NOx) has a great relationship with the temperature. Especially when the temperature is high enough, the generation amount of nitrogen oxides (NOx) increases. As the reaction temperature (t) increases, the reaction rate increases exponentially. And when the reaction temperature (t) is less than 1200 °C, the generation amount of nitrogen oxides (NOx) is not large. When the reaction temperature (t) is greater than 1300 °C, for every 100 °C increase, the reaction rate increases by 6 - 7 times.

[0004] It can be found from the above that the generation of nitrogen oxides (NOx) is a slow reaction process, which is formed by the reaction of nitrogen (N) in the combustion air with reactants such as oxygen (O), hydroxide ions (OH), and molecules. Therefore, in the high-temperature decomposition of the incinerator, how to reduce the combustion temperature or reduce the oxygen concentration becomes a very important topic.

[0005] Therefore, in view of the above deficiencies, the inventor hopes to propose an incinerator device with reduced nitrogen oxides that has the efficacy of reducing the generation of nitrogen oxides, enabling users to easily operate and assemble. Summary of the Invention

[0006] The main object of the present invention is to provide an incinerator device with reduced nitrogen oxides. The incinerator device mainly includes a furnace chamber, an air duct, a burner head, and a combined design of an enclosure and a shield. Through the air duct, the gas to be treated (such as a mixture of one or more volatile organic compounds and air) can be transported to the air outlet, and flows out through the air passage left between the air outlet and the enclosure and reaches the front end of the combustion flame generated by the burner head, so as to increase the destruction efficiency of the volatile organic compounds contained in the gas to be treated. On the other hand, the combustion-supporting gas (such as air or oxygen) entering through the combustion-supporting gas inlet of the burner head is designed to be increased by more than 20% to 30% of the combustion equivalence ratio. The excess combustion-supporting gas can cause the temperature of the combustion flame generated by the burner head to drop. Thus, after the gas to be treated (such as a mixture of one or more volatile organic compounds and air) passes through the generated combustion flame, the generation of nitrogen oxides can be reduced, and the efficiency of reducing the generation of nitrogen oxides is achieved, thereby increasing the overall practicality.

[0007] A secondary object of the present invention is to provide an incinerator device with reduced nitrogen oxides. The burner head is provided with a channel, and the gas fuel pipe has a gas fuel inlet, at least one first-stage gas port, and at least one second-stage gas port. The first-stage gas port of the gas fuel pipe is arranged in the channel of the burner head. When the combustion-supporting gas can enter the channel of the burner head, the combustion-supporting gas can first be pre-mixed with a part of the gas fuel ejected from the first-stage gas port of the gas fuel pipe in the channel of the burner head. Then, the combustion-supporting gas mixed with a part of the gas fuel flows to the second-stage gas port of the gas fuel pipe and is further mixed with the gas fuel ejected from the second-stage gas port. Thus, through the two-stage injection of gas fuel, the pre-mixing sequence and distribution of the combustion flame can be made more uniform, reducing the generation of nitrogen oxides, achieving the effect of improving the nitrogen oxide emissions, and further increasing the overall efficiency.

[0008] Another object of the present invention is to provide an incinerator device with reduced nitrogen oxides. The burner head is combined with the furnace chamber, and the burner head shield of the burner head is located at the second-stage gas port of the gas fuel pipe. One end of the enclosure is combined with the burner head shield, and the other end of the enclosure passes through the air outlet of the air duct. The air outlet of the air duct is larger than the enclosure, so that an air passage is left between the air outlet of the air duct and the enclosure. When the gas fuel is ejected from the second-stage gas port and generates a combustion flame, the combustion flame passes through the burner head shield of the burner head and through the enclosure, and the enclosure can prevent the combustion flame from being affected by the gas to be treated (such as a mixture of one or more volatile organic compounds and air) entering and affecting the ejection direction of the combustion flame, making the combustion flame gather into a beam shape, having a concentrated effect, and further increasing the overall usability.

[0075] The incinerator device with reduced nitrogen oxides of the present invention mainly includes a combined design of a furnace chamber 10, an air duct 20, a burner head 30 and a surrounding shield 40 (such as Figures 1 through 3 shown).

Additionally, the gas fuel 70 is ejected from the second-stage gas port 323 and generates a combustion flame 324 (as Figure 2 shown). Furthermore, the burner head 30 is coupled to the furnace chamber 10, where the burner head shield 31 is provided with a mounting panel (not shown in the figure) and is mounted on the furnace chamber 10 through the mounting panel, such that a part of the burner head 30 is exposed outside the furnace chamber 10, and the gas fuel inlet 321 of the gas fuel pipe 32 is provided outside the furnace chamber 10 (as Figure 2 shown) to facilitate the entry of the gas fuel 70 through the gas fuel inlet 321. Additionally, the combustion-supporting gas inlet 33 is also provided outside the furnace chamber 10 (as Figure 2 shown) to facilitate the entry of the combustion-supporting gas 60 through the combustion-supporting gas inlet 33.

[0077] Additionally, the air duct 20 is provided within the furnace chamber 10, where at least one heat-insulating cotton 23 is provided between the air duct 20 and the furnace chamber 10 (as Figure 2 shown) to form a barrier protection, and the air duct 20 is made of a metal material, and the air duct 20 is connected to the gas inlet 11 of the furnace chamber 10 to enable the gas to be treated 50 (such as a mixture containing one or more volatile organic compounds and air) to enter the air duct 20, and the air duct 20 is provided with an air outlet 21.

When the combustion-supporting gas 60 can enter the passage 301 of the burner 30, the combustion-supporting gas 60 can first be pre-mixed with a part of the gaseous fuel 70 ejected from the first-stage gas port 322 of the gaseous fuel pipe 32 in the passage 301 of the burner 30. The combustion-supporting gas 60 mixed with a part of the gaseous fuel 70 then flows to the second-stage gas port 323 of the gaseous fuel pipe 32 and is mixed with the gaseous fuel 70 ejected from the second-stage gas port 323 again. Thus, by injecting the gaseous fuel 70 in two stages, the pre-mixing sequence and distribution of the combustion flame 324 can be more uniform, and the excess combustion-supporting gas 60 can reduce the temperature of the combustion flame 324 generated by the burner 30, so that the gas to be treated 50 can reduce the generation of nitrogen oxides after passing through the generated combustion flame 324, and has the effect of reducing the generation of nitrogen oxides.
