Description

Technical Field

[0001] The utility model relates to the technical field of burnt tail gas treatment, in particular to a burnt tail gas treatment structure of a butene isomerization device reactor. Background Art

[0002] The butene isomerization unit is a chemical unit used to convert butene (an olefin compound) into other isomers. In this process, some charred tail gas will be produced. Charred tail gas is a waste gas produced in certain industrial processes, usually related to combustion, high-temperature reaction or pyrolysis. An effective treatment structure is required to reduce the adverse impact on the environment.

[0003] The existing reactor of the butene isomerization unit adopts a series mode of air injection and layer-by-layer charring.

[0004] The existing patent (Announcement No.: CN207187709U) is a high-efficiency butene isomerization unit reactor. This unit has improved the regeneration process and adopted a multi-stage air injection and parallel coking mode.

[0032] Specifically, Figure 4As shown, the combustion-supporting assembly 3 includes an extension plate 301, a gas tank 302 and a connecting pipe 303. The extension plate 301 is fixedly connected to one side of the support column 201, the gas tank 302 is bolted to the top of the extension plate 301, one end of the connecting pipe 303 is arranged at the top of the gas tank 302 and the other end is arranged inside the tank body 1 and used in conjunction with the gas tank 302.

[0033] Specifically, Figure 4 As shown, the protection assembly 4 includes a protection shell 401 and refractory bricks 402 . The protection shell 401 is welded to one side of the tank body 1 , and the refractory bricks 402 are arranged between the protection shell 401 and the tank body 1 .

[0034] Through the above technical scheme, the inlet 202 is used to discharge the burnt exhaust gas into the interior of the tank body 1, and then the organic matter in the burnt exhaust gas is converted into carbon dioxide and water vapor through the high-temperature combustion of the combustion furnace 205, and then oxygen is filled into the interior of the tank body 1 through the connecting pipe 303 to allow the burnt exhaust gas to be fully burned. The protective shell 401 and the refractory bricks 402 can block the heat inside the tank body 1 to prevent the heat inside the tank body 1 from affecting the external environment, and then the exhaust gas is discharged through the outlet 203 and the outlet valve 204.

[0035] Specifically, Figure 5 As shown, the adsorption assembly 5 includes a filter bin 501, a clamping block 502, an activated carbon placement net 503 and a sealing door 504.

[0038] Through the above technical solution, the exhausted gas will enter the interior of the filter bin 501 and then the activated carbon placed on the activated carbon placement net 503 will adsorb the residual organic matter in the exhaust gas onto the surface of the activated carbon to filter the gas. The activated carbon can be easily replaced through the sealing door 504. The gas passing through the filter bin 501 will enter the interior of the separation bin 601. When passing through the condenser 607, water vapor will be separated from the exhaust gas, and when it contacts the separation disc 603 and the receiving ring 605, liquid water will be formed and attached to the separation disc 603 and the receiving ring 605. Then the water column will flow along the separation disc 603, the receiving ring 605 and the barrel-shaped net 604 into the interior of the storage bin 606 for storage, which can be used for recycling. Finally, the gas will enter the interior of the exhaust pipe 701 again, be filtered by multiple filter nets 702, and finally be discharged.

[0039] Specifically, Figure 5 As shown, an exhaust gas monitor 8 is provided on one side of the exhaust pipe 701, and the exhaust gas monitor 8 is used to detect the components of the gas.

[0040] Specifically, Figure 5 As shown, a protective cover 9 is provided on one side of the exhaust pipe 701 .

[0041] Through the above technical solution, the exhaust gas monitor 8 is used to detect the components of the gas, and the protective cover 9 can prevent foreign matter from entering the exhaust pipe 701 and protect the filter 702 at the same time.

[0042] By adopting the above technical solution, the problem that the existing butene isomerization unit reactor burnt tail gas treatment structure is relatively rough in treating the burnt tail gas is solved.

[0043] Working principle: When the present application is used, the feed port 202 is first used to discharge the burnt exhaust gas into the interior of the tank body 1, and then the organic matter in the burnt exhaust gas is converted into carbon dioxide and water vapor through the high temperature combustion of the combustion furnace 205, and then oxygen is filled into the interior of the tank body 1 through the connecting pipe 303 to make the burnt exhaust gas fully combust. The protective shell 401 and the refractory bricks 402 can block the heat inside the tank body 1 to prevent the heat inside the tank body 1 from affecting the external environment, and then the exhaust gas is discharged through the discharge port 203 and the discharge valve 204. The discharged gas will enter the interior of the filter bin 501 and then the residual gas in the exhaust gas will be removed by the activated carbon placed on the activated carbon placement net 503. The remaining organic matter is adsorbed onto the surface of the activated carbon to filter the gas. The activated carbon can be easily replaced through the sealing door 504. The gas passing through the filter chamber 501 will enter the interior of the separation chamber 601. When passing through the condenser 607, the water vapor will be separated from the exhaust gas, and when it contacts the separation plate 603 and the receiving ring 605, liquid water will be formed and attached to the separation plate 603 and the receiving ring 605. Then the water column will flow along the separation plate 603, the receiving ring 605 and the barrel-shaped net 604 into the storage chamber 606 for storage, which can be used for recycling. Finally, the gas will enter the exhaust pipe 701 again, be filtered by multiple filter nets 702, and finally be discharged.
