Detailed Implementation

[0016] like Figures 1 to 6 The diagram shows a high-temperature exhaust gas collection hood with a cooling and reducing diameter. The inlet end of the reducing pipe 2 is sealed and connected to the high-temperature exhaust gas collection hood 1 via a flange, and the outlet end of the reducing pipe 2 is also sealed and connected to the exhaust gas collection pipe 3 via a flange. The reducing pipe 2 is used for exhaust gas cooling and filtration, and the sealing material used for the flange connection is asbestos sealing material.

[0017] The inlet end of the variable diameter pipe 2 is equipped with several surrounding separators 4, which effectively intercept particulate matter and oil particles in the exhaust gas. The surrounding separators 4 are arranged in an alternating manner at the inlet end of the variable diameter pipe 2, with an alternation depth of two-thirds. A stainless steel metal mesh plate 7 with a thickness of 30 mm is installed inside the surrounding separator 4. Several heat pipes 6 are installed in the variable diameter pipe 2, and working fluid is injected into the heat pipes 6 for heat exchange. The heat pipe 6 includes an evaporation section 8 and a condensation section 9. The evaporation section 8 is located inside the variable diameter pipe 2 and has several fins 10 arranged axially to absorb heat from the high-temperature exhaust gas and exchange heat with the working fluid in the heat pipe 6 for evaporation. The condensation section 9 is located outside the variable diameter pipe 2 and is connected to a radiator 5 for heat exchange with the working fluid in the heat pipe 6 for condensation. The fins 10 and the radiator 5 are tightly fixed to the heat pipe 6 with fasteners. The heat pipe 6 covers a variable diameter cross-sectional area of ​​400 mm2.

[0018] In this embodiment, the high-temperature exhaust gas collection hood 1 absorbs the high-temperature exhaust gas and transmits it to the variable diameter pipe 2. The surrounding separator 4, located at the inlet end of the variable diameter pipe 2, can effectively intercept particulate matter and oil particles in the high-temperature exhaust gas, ensuring exhaust gas purification. The high-temperature exhaust gas comes into contact with the fins 10 and exchanges heat with the working fluid in the evaporation section 8 of the heat pipe 6. After absorbing heat, the working fluid evaporates and enters the condensation section 9, where it exchanges heat with the radiator 5 to achieve heat dissipation. At this time, the working fluid after heat exchange liquefies and then flows back into the evaporation section 8 under the action of capillary suction and gravity, repeating the above process to continuously cool the exhaust gas.

[0019] The above embodiments are merely illustrative examples of this utility model and are not intended to limit the scope of protection of this utility model. Those skilled in the art can make simple changes or substitutions based on the above embodiments without departing from the technical concept of this utility model, but these changes will still fall within the scope of protection of this utility model.
