Abstract
Description
Technical Field

[0002] Industrial kiln flue gas refers to the heat generated from burning gaseous fuels (natural gas, coal gas, etc.), liquid fuels (diesel, gasoline, methanol, etc.), or solid fuels (coal, etc.) to heat equipment to meet operating requirements. During combustion, these fuels, due to their inherent characteristics or changes in combustion conditions, will form various environmentally harmful substances in the flue gas (such as dust, aliphatic hydrocarbons, sulfur dioxide, etc.). With increasing public awareness of environmental protection and stricter national environmental regulations, enterprises must treat their flue gas emissions to meet relevant national standards.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0047] like Figures 1-4As shown, an industrial kiln flue gas emission treatment device according to an embodiment of the present disclosure is illustrated. It includes an emission pipe 1, a gathering box 2, a water tank 3, a flow guiding mechanism, a stirring mechanism, and a conveying mechanism. The gathering box 2 has a conical design, wider at the bottom and narrower at the top, which can gather dispersed flue gas and concentrate the heat generated when the flue gas impacts the water tank 3. The gathering box 2 is fixedly connected inside the emission pipe 1. The water tank 3 is located at the top of the gathering box 2 and inside the emission pipe 1. The flow guiding mechanism facilitates the gathering and blowing of heated flue gas towards the water tank 3, thus accumulating heat. The flow guiding mechanism also facilitates uniform contact between the flue gas and the water tank 3. The stirring mechanism agitates the water in the water tank 3, thereby improving the efficiency of heat recovery from the flue gas and reducing the waste of heat energy in the flue gas.
[0048] The flow guiding mechanism is located at the top of the gathering box 2 and is used to distribute the flue gas onto the surface of the water tank 3. The flow guiding mechanism includes a connecting box 4, a distribution box 5, distribution plates 6, and a filter assembly. Each pair of adjacent distribution plates 6 forms multiple air ducts within the distribution box 5. A connecting groove is provided at the bottom of the distribution box 5, the length of which covers multiple distribution plates 6, facilitating the dispersion of flue gas within each air duct and ensuring uniform contact between the flue gas and the water tank 3. The connecting box 4 is connected to the top of the gathering box 2, and the distribution box 5 is connected to the top of the connecting box 4. Multiple distribution plates 6 are provided, and each distribution plate 6 is fixedly connected to the inner wall of the distribution box 5. The filter assembly... The filter assembly, located on the distribution box 5, is used for secondary filtration of flue gas. It includes a filter box 7 and a filter plate 8. The filter box 7 is connected to the top of the distribution box 5, and the filter plate 8 is fixedly connected inside the filter box 7. Specifically, the flue gas enters the gathering box 2, which gathers the flue gas, causing the heat in the flue gas to concentrate and pass through the connecting box 4 into the distribution box 5 and be blown towards the water tank 3. The distribution plate 6 evenly distributes the flue gas, ensuring that the flue gas fully contacts the water tank 3, thereby heating the water in the water tank 3. After contacting the water tank 3, the flue gas continues to rise and enters the filter box 7, where it is further filtered by the filter plate 8.
[0049] The stirring mechanism is installed on the water tank 3 to agitate the water inside. The stirring mechanism includes a stirring rod 9, a stirring plate 10, and a first motor 11. The stirring rod 9 is inclined inside the water tank 3, which allows the first motor 11 to penetrate at a higher position, reducing the risk of water leakage from the water tank 3. The stirring rod 9 is rotatably connected inside the water tank 3, and the stirring plate 10 is fixedly connected to the stirring rod 9. The first motor 11 is installed on one side of the water tank 3, and its output end penetrates the water tank 3 and is fixedly connected to one end of the stirring rod 9. Specifically, the first motor 11 drives the stirring rod 9 to rotate, and when the stirring rod 9 rotates, it drives the stirring plate 10 to agitate the water inside the water tank 3, so that the water is evenly in contact with the inner wall of the water tank 3, improving the heating efficiency of the water.
[0050] The conveying mechanism is installed on the water tank 3 and is used to add and release water into the water tank 3. The conveying mechanism includes: an input pump 12, an input pipe 13, an output pump 14, and an output pipe 15. The input pump 12 is installed on one side of the water tank 3, and the output end of the input pump 12 is connected to the water tank 3. The input pipe 13 is connected to the input end of the input pump 12. The output pump 14 is installed on the other side of the water tank 3, and the input end of the output pump 14 is connected to the water tank 3. The output pipe 15 is connected to the output end of the input pump 12. The ends of the input pipe 13 and the output pipe 15 that are far apart from each other are fixedly connected to flanges 16. Specifically, cold water is conveyed into the water tank 3 through the input pipe 13 and the input pump 12. After the water in the water tank 3 is heated, hot water is output through the output pump 14 and the output pipe 15 for subsequent use.
[0051] In this embodiment, currently, flue gas is directly discharged after treatment, making it difficult to recover the heat energy in the flue gas. However, in this application, the flue gas enters the gathering box 2, which gathers the flue gas, allowing the heat in the flue gas to concentrate and pass through the connecting box 4 into the distribution box 5 and be blown towards the water tank 3. The distribution plate 6 evenly distributes the flue gas, ensuring that the flue gas fully contacts the water tank 3. The first motor 11 drives the stirring rod 9 to rotate, which in turn drives the stirring plate 10 to agitate the water in the water tank 3, thus ensuring that the water evenly contacts the inner wall of the water tank 3 and improving the heating efficiency of the water. After the water in the water tank 3 is heated, the hot water is output through the output pump 14 and the output pipe 15 for subsequent use. Then, cold water is transported into the water tank 3 through the input pipe 13 and the input pump 12 for further heating. After contacting the water tank 3, the flue gas continues to rise and enters the filter box 7, where it is filtered again by the filter plate 8 before being discharged.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
