Abstract

The present invention is an incinerator device with the function of reducing nitrogen oxides. The incinerator device mainly comprises a combination design of a furnace, an air duct, a furnace head and a surrounding shield. The gas to be treated is transported to the air outlet through the air duct, and flows out through the air duct left between the air outlet and the surrounding shield to the front end of the combustion flame generated by the furnace head, so as to increase the destruction efficiency of volatile organic compounds contained in the gas to be treated. On the other hand, the combustion-supporting gas entering the combustion-supporting gas inlet of the furnace head is designed to increase by 20% to 30% over the combustion equivalent, and the excess combustion-supporting gas can reduce the temperature of the combustion flame generated by the furnace head. As a result, the gas to be treated (such as a mixed gas containing one or more volatile organic compounds and air) can reduce the generation of nitrogen oxides after passing through the generated combustion flame, and has the effect of reducing the generation of nitrogen oxides.

Description

Incinerator device for reducing nitrogen oxides

The present invention relates to an incinerator device capable of reducing nitrogen oxides, in particular, an incinerator device or similar equipment capable of reducing the generation of nitrogen oxides by passing the gas to be treated (such as a mixed gas containing one or more volatile organic compounds and air) through the generated combustion flame, and is suitable for use in the semiconductor industry, optoelectronic industry or chemical-related industries.

Currently, volatile organic gases (VOCs) are generated in the manufacturing process of the semiconductor industry or the optoelectronic industry. The VOCs contain compounds such as nitrogen oxides (NOx) and sulfur oxides (SOx). Compounds such as nitrogen oxides (NOx) and sulfur oxides (SOx) are one of the important causes of photochemical smog, acid rain and human respiratory diseases.

The current industry practice for volatile organic gases (VOCs) is to first perform adsorption and desorption processes on a rotor, and then send the concentrated desorbed gas into the incinerator for high-temperature decomposition. However, during the high-temperature decomposition process, the generation of nitrogen oxides (NOx) is closely related to temperature, especially when the temperature is high enough, the generation of nitrogen oxides (NOx) increases. As the reaction temperature (t) increases, the reaction rate increases exponentially. When the reaction temperature (t) is less than 1200 degrees C, the generation of nitrogen oxides (NOx) is not large. When the reaction temperature (t) is greater than 1300 degrees C, the reaction rate increases by 6 to 7 times for every 100 degrees C increase.

From the above, it can be found 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) and hydrogen 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 issue.

Therefore, in view of the above shortcomings, the inventors of the present invention hope to propose an incinerator device with the effect of reducing the production of nitrogen oxides, which can be easily operated and assembled by users. The inventors of the present invention have devoted themselves to the research and design of the device to provide convenience to users, which is the motivation for the invention.

The main purpose of the present invention is to provide an incinerator device with the function of reducing nitrogen oxides. The incinerator device mainly comprises a combination design of a furnace, an air duct, a furnace head and a surrounding shield, and the gas to be treated (such as a mixed gas containing one or more volatile organic compounds and air) can be transported to the air outlet through the air duct, and flow out through the air duct left between the air outlet and the surrounding shield to the front end of the combustion flame generated by the furnace head, so as to increase the volatile organic compounds contained in the gas to be treated. The destruction efficiency of the material is improved, and on the other hand, the combustion-supporting gas (such as air or oxygen) entering the combustion-supporting gas inlet of the furnace head is designed to increase by 20% to 30% more than the combustion equivalent, and the excess combustion-supporting gas can reduce the temperature of the combustion flame generated by the furnace head. As a result, the gas to be treated (such as a mixed gas containing one or more volatile organic compounds and air) can reduce the generation of nitrogen oxides after passing through the generated combustion flame, and has the effect of reducing the generation of nitrogen oxides, thereby increasing the overall practicality.

The second object of the present invention is to provide an incinerator device with the function of reducing nitrogen oxides, wherein a passage is provided through the furnace head, and the gas fuel pipe has a gas fuel inlet, at least one first gas port and at least one second gas port, and the first gas port of the gas fuel pipe is provided in the passage of the furnace head. When the combustion-supporting gas can enter the passage of the furnace head, the combustion-supporting gas can firstly be separated in the passage of the furnace head and the gas fuel pipe from the second gas port of the gas fuel pipe. Part of the gas fuel sprayed from the first gas port is pre-mixed, and the combustion-supporting gas mixed with the part of the gas fuel flows to the second gas port of the gas fuel pipe and is re-mixed with the gas fuel sprayed from the second gas port. Thus, through the two-stage injection of gas fuel, the pre-mixing sequence and distribution of the combustion flame can be more uniform, reducing the generation of nitrogen oxides, thereby achieving the effect of improving nitrogen oxide emissions and increasing the overall efficiency.

Another object of the present invention is to provide an incinerator device with a function of reducing nitrogen oxides, wherein the furnace head is coupled to the furnace chamber, and the furnace head shield of the furnace head is located at the second gas port of the gas fuel pipe, and one end of the surrounding shield is coupled to the furnace head shield, and the other end of the surrounding shield passes through the air outlet of the air duct, wherein the air outlet of the air duct is larger than the surrounding shield, so that there is an air gap between the air outlet of the air duct and the surrounding shield. When the gas fuel is ejected from the second gas port and generates a combustion flame, the combustion flame passes through the surrounding shield from the furnace shield of the furnace head, and the surrounding shield allows the combustion flame to avoid being entered by the gas to be treated (such as a mixed gas containing one or more volatile organic compounds and air) to affect the ejection direction of the combustion flame, so that the combustion flame can be gathered into a beam, which has a concentration effect, thereby increasing the overall usability.
