Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a treatment device for flue gas from carbon anode roasting. Background Technology

[0002] The flue gas emitted during carbon anode roasting contains harmful substances such as sulfur dioxide, fluorides, asphalt fumes, nitrogen oxides, and dust. Treating this exhaust gas usually requires steps such as dust removal and cooling, and desulfurization. Specific equipment includes dust removal and cooling chambers, desulfurization towers, and flue gas exhaust towers. These devices can effectively treat the harmful substances in the exhaust gas and ensure that emissions meet environmental protection standards. This device is a treatment device for carbon anode roasting flue gas.

[0003] The treatment device uses an internal spray system to spray liquid chemicals that come into contact with the rising flue gas, thus treating the flue gas. However, the tower has a large space, resulting in poor mixing between the flue gas and the liquid chemicals.

[0004] Therefore, a device for treating carbon anode roasting flue gas is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a treatment device for carbon anode roasting flue gas, so as to solve the problem of poor mixing effect between the liquid and flue gas inside the treatment device mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a treatment device for carbon anode roasting flue gas, comprising a tower body, a drain pipe, and a flue gas inlet pipe. A drain pipe is installed at the bottom left side of the tower body, and a flue gas inlet pipe is installed on the left side of the tower body. A pipeline-type purification assembly is installed inside the tower body. The pipeline-type purification assembly includes a purification box, a diversion pipe, a packing layer, a spray pipe, and a liquid delivery pipe. A purification box is installed inside the tower body, a diversion pipe is installed inside the purification box, a packing layer is installed inside the diversion pipe, a spray pipe is installed at the top inside the diversion pipe, the left side of the spray pipe extends to the outside of the diversion pipe, and a liquid delivery pipe is installed at the top of the spray pipe, the left side of the liquid delivery pipe extends to the outside of the tower body.

[0007] As a further technical solution of this utility model, several diversion pipes are installed inside the purification box, and the several diversion pipes are distributed at equal intervals.

[0008] As a further technical solution of this utility model, a demister is installed at the top of the inside of the tower body, and a smoke exhaust pipe is installed at the top of the tower body.

[0009] As a further technical solution of this utility model, a return pipe is installed on the right side of the exhaust pipe, and a fan is installed inside the return pipe.

[0010] As a further technical solution of this utility model, a flue body is installed on the right side inside the tower body, and a return groove is provided at the bottom left side inside the flue body, and a flue check valve is installed inside the return groove.

[0011] As a further technical solution of this utility model, a central platform is installed inside the exhaust pipe, and an electric push rod is installed at the top of the central platform.

[0012] As a further technical solution of this utility model, a drive rod is installed at the top of the electric push rod, a cigarette cap is installed at the top of the drive rod, a guide rod is installed at the bottom inside the cigarette cap, and the bottom end of the guide rod extends into the interior of the exhaust pipe.

[0013] As a further technical solution of this utility model, four sets of guide rods are installed at the bottom inside the cigarette cap, and the four sets of guide rods are symmetrically distributed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a purification box, diversion pipes and a packing layer, the purification box is located inside the tower body, and multiple sets of diversion pipes for flue gas flow are installed inside the purification box. After the flue gas enters the tower body, it is diverted from the bottom side into multiple diversion pipes. Each diversion pipe has a spray pipe installed at the top of its interior for spraying liquid medicine. The liquid medicine and flue gas come into contact and mix at the packing layer for purification treatment. Through the diversion of the multiple diversion pipes, the flue gas and liquid medicine are fully mixed and contacted, thus realizing the diversion and purification function inside the treatment device.

[0015] By setting up a return pipe and a flue body, the return pipe connects the exhaust pipe to the flue body inside the tower. When the fan inside the return pipe is started, the treated flue gas inside the exhaust pipe can be driven to enter the flue body through the return pipe. A flue check valve is installed at the return groove at the bottom of the flue body to prevent the flue gas inside the tower from entering the flue body through the flue check valve. The flue gas inside the flue body can re-enter the bottom of the tower body through the flue check valve to continue purification treatment, thus realizing the circulation treatment function when the treatment device is in use.

[0016] By installing a cigarette cap located above the exhaust pipe, the cigarette cap can be raised or lowered by the drive rod when the electric push rod is activated to extend or retract. The size of the exhaust pipe opening can be adjusted by adjusting the distance between the cigarette cap and the exhaust pipe opening. When the cigarette cap is in contact with the exhaust pipe, the exhaust pipe can be closed to prevent the exhaust gas from being discharged, thus realizing the auxiliary control function of the exhaust pipe of the treatment device.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a carbon anode roasting flue gas treatment device, comprising a tower body 1, a drain pipe 2, and a flue gas inlet pipe 3. The drain pipe 2 is installed at the bottom left side of the tower body 1, and the flue gas inlet pipe 3 is installed on the left side of the tower body 1. A pipeline purification component is provided inside the tower body 1. The pipeline purification component includes a purification box 4, a diversion pipe 5, a packing layer 6, a spray pipe 7, and a liquid delivery pipe 8. The purification box 4 is installed inside the tower body 1, and the diversion pipe 5 is installed inside the purification box 4. Several diversion pipes 5 are installed inside the purification box 4, and the several diversion pipes 5 are distributed at equal intervals. The packing layer 6 is installed inside the diversion pipe 5. The spray pipe 7 is installed at the top of the inside of the diversion pipe 5. The left side of the spray pipe 7 extends to the outside of the diversion pipe 5. The top of the spray pipe 7 is installed with a liquid delivery pipe 8, and the left side of the liquid delivery pipe 8 extends to the outside of the tower body 1.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, during use, the multi-component diversion pipe 5 is located inside the purification box 4. After the flue gas is diverted into the multi-component diversion pipe 5, it moves upward. During this process, the spray pipe 7 at the upper position inside the diversion pipe 5 sprays the liquid medicine. The liquid medicine moves downward and gathers with the flue gas at the packing layer 6 to purify the flue gas. The treated debris and sewage flow downward, while the treated flue gas continues to move upward.

[0025] A demister 9 is installed at the top of the tower body 1. A flue pipe 10 is installed at the top of the tower body 1. A return pipe 11 is installed on the right side of the flue pipe 10. A fan 12 is installed inside the return pipe 11. A flue body 13 is installed on the right side of the tower body 1. A return groove 14 is provided at the bottom left side of the flue body 13. A flue check valve 15 is installed inside the return groove 14.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when in use, after starting the fan 12 inside the return pipe 11, the flue gas inside the exhaust pipe 10 can be extracted. After the flue gas enters the flue body 13 through the return pipe 11, it can re-enter the bottom side of the tower body 1 through the flue check valve 15 from the inside.

[0027] A central platform 16 is installed inside the exhaust pipe 10. An electric push rod 17 is installed at the top of the central platform 16. A drive rod 18 is installed at the top of the electric push rod 17. A cigarette cap 19 is installed at the top of the drive rod 18. A guide rod 20 is installed at the bottom inside the cigarette cap 19. The bottom of the guide rod 20 extends into the interior of the exhaust pipe 10. Four sets of guide rods 20 are installed at the bottom inside the cigarette cap 19. The four sets of guide rods 20 are symmetrically distributed.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, when in use, when the electric push rod 17 is activated to perform the telescopic operation, the cigarette cap 19 can be driven to move up and down with the assistance of the drive rod 18. In this way, the distance between the cigarette cap 19 and the exhaust pipe 10 can be adjusted, thereby indirectly adjusting the size of the opening of the exhaust pipe 10.

[0029] Working Principle: During operation, flue gas enters the tower body 1 through the inlet pipe 3 and is then diverted into the multi-group diversion pipes 5. Moving upwards along the diversion pipes 5, the chemical solution enters the spray pipe 7 through the delivery pipe 8 and is sprayed into the diversion pipes 5. The chemical solution and flue gas converge at the packing layer 6. During this convergence, the chemical solution treats the flue gas. The treated wastewater flows downwards and collects at the bottom of the tower body 1. Later, it can be discharged through the drain pipe 2. The treated flue gas rises, passes through the demister 9, and is discharged through the exhaust pipe 10. The exhaust pipe 10 is connected to the main flue duct 13 inside the tower body 1 via the return pipe 11. If the fan 12 inside the return pipe 11 is activated, it can extract... The flue gas inside the exhaust pipe 10 enters the flue body 13 through the return pipe 11. After opening the flue check valve 15 from the inside, the flue gas can re-enter the bottom of the tower body 1 through the flue check valve 15. In this way, the flue gas can be diverted back to the diversion pipe 5 for further purification. A smoke cap 19 is installed above the exhaust pipe 10 and is controlled by an electric push rod 17. When the electric push rod 17 is activated for extension and retraction, the smoke cap 19 can be driven to move up and down with the assistance of the drive rod 18. This allows adjustment of the distance between the smoke cap 19 and the exhaust pipe 10, indirectly adjusting the size of the opening of the exhaust pipe 10. If the smoke cap 19 is in contact with the exhaust pipe 10, the exhaust pipe 10 can be closed to prevent the flue gas from being discharged.
