[0025] See also Figure 1-2 , the utility model provides a technical solution.

[0026] Embodiment 1:

[0027] Please see attached Figure 1-2 In the specific implementation process: an asphalt reactor flue gas treatment mechanism includes: a base 1, a bracket 2 and a flue gas treatment structure; the flue gas treatment structure is installed on the base 1, and the bracket 2 is installed on the base 1;

[0028] The flue gas treatment structure comprises: a combustion component, a cooling component and a filtering component;

[0029] The combustion component is mounted on the bracket 2, the cooling component is mounted on the base 1, and the filtering component is mounted on the base 1;

[0030] The combustion assembly includes: a combustion chamber 3, a burner 4, a connecting pipe 5, an oxygen supply pipe 6, a nozzle 7, and an oxygen tank 8;

[0031] The combustion chamber 3 is installed on the bracket 2, the burner 4 is installed inside the combustion chamber 3, the oxygen tank 8 is installed on the base 1, one end of the oxygen supply pipe 6 is installed on the oxygen tank 8, and the other end is connected to the combustion chamber 3, the nozzle 7 is installed in the combustion chamber 3, located around the burner 4, and the connecting pipe 5 is installed at the air inlet end of the nozzle 7.

[0032] It should be noted that, first, the connecting pipe 5 is connected and sealed to the air outlet of the reactor, and the burner 4 in the combustion chamber 3 installed on the bracket 2 is started. The flue gas generated by the reactor is injected into the nozzle 7 in the combustion chamber 3 through the connecting pipe 5, and sprayed into the flame generated by the burner 4 through the nozzle 7. The spraying speed of the nozzle 7 is controlled to make the flue gas fully burn. During the combustion process, the oxygen tank 8 installed on the base 1 is started, and the oxygen in the oxygen tank 8 is supplied to the combustion chamber 3 through the oxygen supply pipe 6, so that the oxygen in the combustion chamber 3 is sufficient, so that the flue gas can be fully burned, and only carbon dioxide and water are produced in the flue gas after combustion, with less pollution and low treatment cost.

[0033] As a preferred solution, further, a controller is provided outside the combustion chamber 3 .

[0034] It should be noted that a controller is provided outside the combustion chamber 3 to facilitate the control of the supply speed of the flue gas and to control the startup of the entire equipment.

[0035] As a preferred solution, further, the cooling assembly includes: an exchange tube 9, a cold water pipe 10, a water outlet pipe 11, a temperature measuring device 12, a display 13, and an exchange box 14;

[0036] The exchange box 14 is installed on the base 1, the exchange tube 9 is installed in the exchange box 14, the cold water pipe 10 is installed on the exchange box 14, the outlet pipe 11 is installed on the exchange box 14, the temperature measuring device 12 is installed in the exchange box 14, and the display 13 is installed on the exchange box 14.

[0037] It should be noted that the flue gas after full combustion contains a large amount of heat, and the heat needs to be recovered to cool the flue gas. The flue gas after combustion enters the exchange tube 9, and cold water is injected into the exchange box 14 installed on the base 1 through the cold water pipe 10 in advance. When the flue gas passes through the exchange tube 9 installed in the exchange box 14, the heat in the flue gas will be fully in contact with the cold water in the exchange box 14 through the spiral exchange tube 9, and the heat is transferred, so that the cooling process of the flue gas is completed. At the same time, the temperature of the cold water in the exchange box 14 is measured by the temperature measuring device 12 installed in the exchange tube 9, and the temperature is displayed in a limited time through the display installed on the exchange box 14. When the temperature reaches a certain value, the processing work is suspended, and the warm water in the exchange box 14 is discharged from the exchange box 14 through the outlet pipe 11, and the exchange box 14 is filled with cold water again through the cold water pipe 10, and the processing work is started again, so that the heat in the flue gas can be repeatedly obtained, saving resources.

[0041] The filter box 18 is installed on the base 1 , the aeration pipe 16 is installed in the filter box 18 , the air inlet pipe 15 is connected to the exchange pipe 9 at one end and installed on the aeration pipe 16 at the other end, and the air outlet pipe 17 is installed on the filter box 18 .

[0042] It should be noted that the cooled flue gas enters the aeration pipe 16 through the air inlet pipe 15, and is fully contacted with the reaction liquid in the filter box 18 through the aeration pipe 16, which can effectively eliminate the untreated sulfur dioxide gas in the flue gas. The aerated flue gas is discharged into the air through the exhaust pipe 17, so that the flue gas discharged into the air contains only carbon dioxide and inert gases, which has less pollution and effectively protects the environment.

[0043] As a preferred solution, further, a reaction liquid (containing purple litmus aqueous solution) is arranged in the filter box 18 .
