[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figures 1-2 An embodiment of this utility model provides a cooling recovery mechanism for a steam pyrolysis furnace, comprising:

[0029] Processing system 1 is used to remove tar and chlorides from the gas generated by the steam pyrolysis furnace;

[0030] Condenser 2, connected to processing system 1, is used to condense water and oil in the gas;

[0031] Coolant circulation system 3 is connected to condenser 2 and is used to cool the condensing medium in condenser;

[0032] Gas-liquid separator 4 is connected to condenser 2 and is used to separate the condensed gas and liquid.

[0033] The liquid storage tank 5 is connected to the gas-liquid separator 4 and is used to collect the liquid separated by the gas-liquid separator 4.

[0034] In this embodiment, when treating the gas generated by the steam pyrolysis furnace, it is first injected into the treatment system 1 to remove tar and chlorides. Then, the gas passes through a condenser 2, where the water and oil carried in the gas are condensed into liquid. A cooling liquid circulation system 3 is installed outside the condenser 2 to maintain it at a low temperature, ensuring effective gas condensation. In the gas-liquid separation tank 4, the condensed liquid and gas are separated by gravity. The gas is discharged for further processing, while the liquid is collected in a liquid storage tank 5. The cooling and recovery mechanism of this application, through the coordinated operation of its components, removes tar and chlorides from the gas generated by the steam pyrolysis furnace and recovers water and oil, protecting the environment and conserving resources.

[0035] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the processing system 1 includes a housing 11, which has an input port 12 and an output port 13. Several filters 14 are arranged inside the housing 11 near the input port 12, and a reaction medium 15 is filled inside the housing 11 between the filters 14 and the output port 13.

[0036] In this embodiment, the inlet 12 is connected to the steam pyrolysis furnace through a pipeline. The gas generated by the steam pyrolysis furnace enters the chamber 11 through the inlet 12 and the temperature decreases. The tar condenses into liquid at 200°C. The tar in the gas is first removed by the filter screen 14. Then, the chloride contained in the gas is removed by the reaction medium 15. Finally, the gas is output through the outlet 13, which has a good gas treatment effect.

[0037] In a preferred embodiment, such as Figure 1 As shown, the input end of the condenser 2 is connected to the output end of the processing system 1 through the first pipeline 21. The gas processed by the processing system 1 enters the condenser 2 for condensation through the first pipeline 21. A first shut-off valve 22 is provided on the first pipeline 21 to control the opening and closing of the first pipeline 21.

[0038] In a preferred embodiment, such as Figure 1 As shown, the output end of the condenser 2 is connected to the top of the gas-liquid separator 4 through the second pipeline 41. The condensed liquid and gas enter the gas-liquid separator 4 through the second pipeline 41 for separation. A second shut-off valve 42 is provided on the second pipeline 41 to control the opening and closing of the second pipeline 41.

[0039] In a preferred embodiment, such as Figure 1 As shown, an exhaust port is provided on one side of the gas-liquid separator 4 near the top to allow the separated gas to be discharged; a flange 43 is fixedly connected to the exhaust port for connecting pipelines to allow the gas to be transmitted to subsequent processes for processing.

[0040] In a preferred embodiment, such as Figure 1 As shown, the liquid storage tank 5 is located below the gas-liquid separator 4. A liquid level pipe 51 is connected to one side of the liquid storage tank 5, a drain valve 52 is connected to the lower part of one side of the liquid storage tank 5, and an oil drain valve 53 is connected to the upper part of one side of the liquid storage tank 5.

[0041] In this embodiment, the liquid separated by the gas-liquid separator 4 contains water and oil. After entering the liquid storage tank 5 for a period of time, due to density differences, water and oil separate into layers. The separation position can be observed through the liquid level pipe 51. Water or oil can be discharged separately through the drain valve 52 and the oil drain valve 53, respectively, to achieve separation and collection.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
