Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to a rapid cooling device for combustion exhaust gas. Background Technology

[0002] Fuel combustion is a violent oxidation reaction process. In industrial production scenarios such as thermal power generation, steel smelting, and chemical production, combustion exhaust gases are produced whenever fuel combustion is involved. Common fuels include coal, oil, natural gas, and biomass. These gases harm human health, causing respiratory and cardiovascular diseases, and also damage the environment, leading to global warming and ecological imbalance.

[0003] In industrial production processes, many combustion devices produce high-temperature exhaust gases. If these high-temperature exhaust gases are directly emitted, they will not only cause thermal pollution to the environment, but may also affect the normal operation of subsequent exhaust gas treatment processes. For example, some purification equipment has strict requirements on exhaust gas temperature. High-temperature exhaust gases will reduce purification efficiency or even damage the equipment. At present, common exhaust gas cooling devices have problems such as low cooling efficiency, complex structure, and high energy consumption. For example, traditional air-cooled cooling devices rely on natural air convection or forced ventilation by fans for cooling, which is slow and difficult to meet the needs of rapid cooling.

[0004] To address the above issues, we have developed a rapid cooling device for combustion exhaust gases. Utility Model Content

[0005] This utility model discloses a rapid cooling device for combustion exhaust gas, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid cooling device for combustion exhaust gas includes a base plate, a fixed seat fixedly connected to one side of the top of the base plate, a connecting seat fixedly connected to the top of the fixed seat, a protective shell threadedly connected to one side of the connecting seat, a filter threadedly connected to one side of the connecting seat and inside the protective shell, an air inlet pipe fixedly connected to the side of the connecting seat away from the protective shell, one end of the air inlet pipe extending into the interior of the connecting seat, and an air outlet pipe fixedly connected to one end of the outer side of the protective shell, the bottom of the air outlet pipe extending into the interior of the protective shell.

[0008] The base plate provides a stable support foundation, and the fixing seat serves as a fixed connection seat. The protective shell is threaded onto the connection seat for easy installation and disassembly, and can protect internal components such as filters from damage caused by external factors. The filter filters the combustion exhaust gas entering the device, removing impurities and particulate matter to prevent these impurities from adversely affecting the subsequent cooling process and equipment, thereby improving the quality of exhaust gas treatment. The inlet and outlet pipes ensure the normal flow of exhaust gas within the device.

[0009] In a preferred embodiment, a cooling box is fixedly connected to the top of the base plate and the end away from the fixing seat, and a circulating cooling pipe is fixedly connected inside the cooling box.

[0010] By setting up a cooling box, a cooling environment is provided for the circulating cooling pipe, which provides the necessary conditions for cooling the exhaust gas. When the combustion exhaust gas flows in the circulating cooling pipe, it exchanges heat with the coolant, thereby achieving rapid cooling of the exhaust gas and reducing its temperature.

[0011] In a preferred embodiment, the top of the circulating cooling pipe extends above the cooling tank and is threadedly connected to a connecting pipe, the end of which, away from the circulating cooling pipe, is threadedly connected to the top of the exhaust pipe.

[0012] By setting up a connecting pipe to connect the circulating cooling pipe and the exhaust pipe via a threaded connection, installation and disassembly are convenient. This ensures that the pre-treated exhaust gas exiting from the exhaust pipe can smoothly enter the circulating cooling pipe for cooling, thus serving as a connection and transition.

[0013] In a preferred embodiment, the bottom of the circulating cooling pipe extends to the bottom of the cooling box and is threadedly connected to an exhaust pipe, the end of which, away from the circulating cooling pipe, is connected to an external exhaust device.

[0014] By setting up an exhaust pipe that connects to the circulating cooling pipe and the external exhaust equipment via a threaded connection, the cooled exhaust gas is discharged, thus completing the entire exhaust gas treatment process.

[0015] In a preferred embodiment, a liquid filling pipe is fixedly connected to the top of the cooling tank, and a sealing cap is threadedly connected to the top of the liquid filling pipe.

[0016] A filling pipe is installed to add coolant to the cooling tank, and a sealed cap prevents coolant leakage and external impurities from entering the cooling tank.

[0017] In a preferred embodiment, a drain pipe is fixedly connected to the bottom of the cooling tank, the top of the drain pipe extends into the interior of the cooling tank, and a manual control switch is provided on the outside of the drain pipe.

[0018] A drain pipe is provided to drain the coolant from the cooling tank, making it convenient to replace or maintain the coolant. A manual control switch controls the opening and closing of the drain pipe.

[0019] The rapid cooling device for combustion exhaust gas provided by this utility model has the following advantages:

[0020] In this invention, the filter filters the combustion exhaust gas entering the device, removing impurities and particulate matter to prevent these impurities from adversely affecting the subsequent cooling process and equipment, thus improving the quality of exhaust gas treatment. On the one hand, when particulate matter in the exhaust gas adheres to the heat exchange surface of the cooling device, it forms a heat insulation layer, hindering heat transfer and reducing heat exchange efficiency. After filtering out these particulate matter, the heat exchange surface can remain clean, making the heat transfer between the cooling medium and the exhaust gas smoother, thereby improving the cooling effect of the cooling device and reducing the exhaust gas temperature more quickly and effectively. On the other hand, as the usage time increases, the filter will gradually become clogged by particulate matter, and its filtration efficiency will continue to decline. The easy replacement of the filter ensures that it can be replaced in time when it reaches a certain service life or becomes clogged, always maintaining a good filtration effect and continuously and effectively removing pollutants from the exhaust gas. Compared with traditional devices, this greatly improves the quality of operation and the efficiency of use. Attached Figure Description

[0029] In this embodiment: the base plate 1 provides a stable support foundation, the fixing seat 2 serves to fix the connecting seat 3, and the protective shell 4 is connected to the connecting seat 3 by threads, which facilitates installation and disassembly and can protect the internal components such as the filter 5, preventing external factors from damaging them. The filter 5 filters the combustion exhaust gas entering the device, removing impurities, particulate matter, etc., to avoid these impurities from adversely affecting the subsequent cooling process and equipment, and improving the quality of exhaust gas treatment. The inlet pipe 6 and the outlet pipe 7 are used to ensure the normal flow of exhaust gas in the device.

[0030] In a preferred embodiment, a cooling box 8 is fixedly connected to the top of the base plate 1 and the end away from the fixing seat 2, and a circulating cooling pipe 9 is fixedly connected inside the cooling box 8.

[0031] In this embodiment, the cooling box 8 provides a cooling environment for the circulating cooling pipe 9, providing the necessary conditions for cooling the exhaust gas. When the combustion exhaust gas flows in the circulating cooling pipe 9, it exchanges heat with the coolant, thereby achieving rapid cooling of the exhaust gas and reducing its temperature.

[0032] In a preferred embodiment, the top of the circulating cooling pipe 9 extends above the cooling tank 8 and is threadedly connected to a connecting pipe 10, the end of the connecting pipe 10 away from the circulating cooling pipe 9 being threadedly connected to the top of the exhaust pipe 7.

[0033] In this embodiment, the connecting pipe 10 connects the circulating cooling pipe 9 and the exhaust pipe 7 via a thread, which facilitates installation and disassembly and ensures that the pre-treated exhaust gas exiting from the exhaust pipe 7 can smoothly enter the circulating cooling pipe 9 for cooling, thus playing a connecting and transitional role.

[0034] In a preferred embodiment, the bottom of the circulating cooling pipe 9 extends to the bottom of the cooling box 8 and is threadedly connected to an exhaust pipe 11, the end of the exhaust pipe 11 away from the circulating cooling pipe 9 being connected to an external exhaust device.

[0035] In this embodiment, the exhaust pipe 11 is connected to the circulating cooling pipe 9 and the external exhaust equipment through a threaded connection, so that the cooled exhaust gas is discharged from the device, thus completing the entire exhaust gas treatment process.

[0036] In a preferred embodiment, a liquid filling pipe 12 is fixedly connected to the top of the cooling tank 8, and a sealing cap is threadedly connected to the top of the liquid filling pipe 12.

[0037] In this embodiment: the liquid filling pipe 12 is used to add coolant to the cooling tank 8, and the sealing cap prevents coolant leakage and external impurities from entering the cooling tank 8.

[0038] In a preferred embodiment, a drain pipe 13 is fixedly connected to the bottom of the cooling tank 8, the top of the drain pipe 13 extends into the interior of the cooling tank 8, and a manual control switch is provided on the outside of the drain pipe 13.

[0039] In this embodiment, the drain pipe 13 is used to drain the coolant in the cooling tank 8, which facilitates the replacement or maintenance of the coolant. The manual control switch controls the opening and closing of the drain pipe 13.

[0040] Working Principle: During use, coolant is added to the cooling tank 8 by opening the sealing cap at the top of the filling pipe 12. After adding, the sealing cap is tightened to ensure the cooling tank 8 is airtight, allowing the coolant to function properly. The exhaust gas produced by combustion enters through the inlet pipe 6, which is connected to the connecting seat 3. The exhaust gas then flows into the filter 5 located inside the protective housing 4. The filter 5 filters impurities and particulate matter in the exhaust gas to reduce wear and contamination of subsequent equipment and improve the overall exhaust gas treatment effect. The filtered exhaust gas is discharged from the protective housing 4 through the outlet pipe 7, the top of which is connected to the connecting pipe 10. The exhaust gas then enters the circulating cooling pipe 9 through the connecting pipe 10. The circulating cooling pipe 9 is located inside the cooling tank 8. The coolant in 8 absorbs the heat of the exhaust gas in the circulating cooling pipe 9, achieving rapid cooling of the exhaust gas. The cooled exhaust gas is discharged from the bottom of the circulating cooling pipe 9 through the exhaust pipe 11, which is connected to the external exhaust equipment. Finally, the exhaust gas is further processed by the external exhaust equipment or discharged to a suitable location. When the coolant needs to be replaced after a period of use, the coolant in the cooling tank 8 is drained by opening the manual control switch outside the drain pipe 13. Then, the steps of adding coolant in the previous preparation are repeated to ensure the cooling effect. After filtering out particulate matter, the heat exchange surface can be kept clean, making the heat transfer between the cooling medium and the exhaust gas smoother, thereby improving the cooling effect of the cooling device and reducing the exhaust gas temperature more quickly and effectively. Compared with traditional devices, it greatly improves the operation quality and usage efficiency.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
