Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas treatment technology, specifically an exhaust gas treatment device for a diffusion furnace. Background Technology

[0002] According to the patent document with authorization announcement number "CN219815782U" and invention title "A Tail Gas Treatment Device for a Diffusion Furnace", the description states: During use, the blower is started, drawing in tail gas from the conveying pipe. The electric push rod is activated, causing the connecting plate to move downwards, which in turn moves the first baffle downwards. When the downward movement stops, two first protrusions insert into the second rectangular groove. The first baffle moves downwards, causing the first rack to move downwards, which in turn drives the gear to rotate. The second rack moves accordingly, causing the second baffle to move and open the air inlet. The tail gas from the diffusion furnace body enters the conveying pipe from the tail gas pipe. The blower sends the tail gas to the compressor, which processes the tail gas and stores it in the tail gas storage tank. The activated carbon adsorption component processes the tail gas in the storage tank. After processing, the tail gas is discharged through the exhaust pipe. After the tail gas is discharged, the blower is turned off, and the electric push rod moves the first baffle upwards to block the conveying pipe. The second baffle moves accordingly to block the air inlet. However, the following defects still exist: During the exhaust gas treatment process, activated carbon may become saturated. Once saturated, activated carbon is difficult to replace, and replacement requires a long shutdown, which reduces the efficiency of exhaust gas treatment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1, by Figures 1-5 The present invention relates to a tail gas treatment device for a diffusion furnace, comprising a treatment box 1, an installation groove 2 provided on the inner side of the treatment box 1, the installation groove 2 being circular, and a rotation adjustment component 3 provided on the inner side of the installation groove 2.

[0016] The rotation adjustment assembly 3 includes a rotating cylinder 301 disposed inside the mounting groove 2. The rotating cylinder 301 has evenly spaced connecting holes 302 on all four sides, forming a material-blocking area on each side. End plates 303 are symmetrically mounted at both ends of the rotating cylinder 301, and partitions 304 are installed at equal angles between the two end plates 303. The two end plates 303, the two adjacent partitions 304, and the material-blocking area form an activated carbon storage chamber. The two end plates 303, the two adjacent partitions 304, and the material-blocking area form an activated carbon storage chamber. The storage chamber can be divided into three parts: one for filling activated carbon, one for absorbing exhaust gas, and one for discharging saturated activated carbon. This allows for quick replacement of activated carbon and easy discharge of saturated activated carbon. A gear ring 305 is coaxially mounted on the side of one end plate 303. An inner exhaust assembly 4 is provided on the inner side of the rotating cylinder 301. A gear 5 is meshed below the gear ring 305. The gear 5 is fixedly connected to the output shaft of the drive motor 6, which is fixedly mounted on the treatment box 1.

[0017] The inner exhaust assembly 4 includes an exhaust pipe 401 disposed inside the rotating cylinder 301. The outer wall of the exhaust pipe 401 is in close contact with the inner wall of the rotating cylinder 301. A connecting groove 404 is provided on one side of the exhaust pipe 401. Two limiting plates 402 are installed on the exhaust pipe 401. The two limiting plates 402 are respectively located on the side of the two end plates 303 that are far away from each other. A connecting frame 403 is installed between the limiting plate 402 on the side away from the toothed ring 305 and the processing box 1.

[0018] The treatment chamber 1 has an air inlet chamber 7 located on the side of the exhaust pipe 401 near the connecting groove 404. An arc-shaped filter screen 8 is installed on one side of the air inlet chamber 7. The air inlet chamber 7 corresponds to the activated carbon storage chamber on the side of the rotating cylinder 301. The arc-shaped filter screen 8 is in close contact with the outer wall of the end plate 303 and the end wall of the partition 304. The activated carbon storage chamber on the side of the rotating cylinder 301 is connected to the air inlet chamber 7. The arc-shaped filter screen 8 is installed on the end face of the air inlet chamber 7, so that the exhaust gas can be filtered through the air inlet chamber 7 during the flow process. The activated carbon in the activated carbon storage chamber can adsorb and treat the exhaust gas, which is convenient for treating the exhaust gas.

[0019] The top of the processing box 1 is equipped with a feeding hopper 10, which corresponds to the activated carbon storage chamber above the rotating cylinder 301, facilitating the feeding of activated carbon into the activated carbon storage chamber.

[0020] The processing box 1 has a discharge trough 11 inside, which is located below the rotating cylinder 301. The discharge trough 11 corresponds to the activated carbon storage chamber below the rotating cylinder 301. The discharge box 12 is installed inside the discharge trough 11 to facilitate the discharge of saturated activated carbon.

[0021] Working principle: When it is necessary to treat the exhaust gas of the diffusion furnace, activated carbon is fed from the feed hopper 10 into the activated carbon storage chamber above. Then, the drive motor 6 is turned on to drive the gear 5 to rotate. Since the gear 5 is meshed with the gear ring 305, it drives the rotating cylinder 301 to rotate, rotating the activated carbon storage chamber containing activated carbon to the side facing the air inlet chamber 7. Connect the inlet pipe 9 to the exhaust pipe of the diffusion furnace so that the exhaust gas from the diffusion furnace enters the inlet chamber 7 through the inlet pipe 9. After being filtered by the arc-shaped filter screen 8, it enters the activated carbon storage chamber. At this time, the activated carbon in the activated carbon storage chamber adsorbs the harmful gases in the exhaust gas. Then the exhaust gas enters the exhaust stack 401 through the connecting groove 404. Then it is passed from the exhaust stack 401 into the subsequent exhaust gas treatment device for further treatment. When the activated carbon in the activated carbon storage chamber is saturated with adsorption, the activated carbon is then placed into the upper activated carbon storage chamber through the feed hopper 10. Then, the drive motor 6 is turned on, driving the gear 5 to rotate. Since the gear 5 is meshed with the gear ring 305, it drives the rotating cylinder 301 to rotate, rotating the activated carbon storage chamber containing new activated carbon to face the air inlet chamber 7, while the activated carbon storage chamber containing saturated activated carbon rotates to the corresponding direction of the discharge trough 11, so that the saturated activated carbon falls into the discharge box 12, making it convenient for the staff to process the saturated activated carbon.
