Abstract

The utility model discloses a converter condensed acid collecting box which comprises a box body, a gas feeding pipe valve, a secondary absorption tower connecting pipe and a condensed acid discharge valve, and the inner side of the box body is fixedly connected with a first-section partition plate, a second-section partition plate, a third-section partition plate and a fourth-section partition plate; sulfur trioxide flows along the position of the input distribution flow channel through the partition of the first-section partition plate, flows to the position of the first-stage separation flow channel after being intercepted by the second-section partition plate, and is conveyed to the second-stage absorption tower through the second-stage absorption tower connecting pipe correspondingly arranged in the area of the first-stage separation flow channel, so that acid liquid in gas can be condensed in advance and recycled, and the recovery rate of the acid liquid is improved.

Description

Technical Field

[0001] This utility model relates to the field of condensed acid treatment technology, and in particular to a converter condensed acid collection box. Background Technology

[0002] Traditional converters typically cool sulfur trioxide to 160–180°C via a V heat exchanger before introducing it into the secondary absorption tower. During this cooling process, condensed acid is generated. This acidic liquid deposits at the bottom of the heat exchange tubes, corroding the lower half of the heat exchanger and causing cross-contamination between the bottom tubes and the tube side, affecting conversion efficiency and service life. A traditional solution to this problem is to use a cylindrical box at the lowest point of the heat exchanger's drainage channel. However, since the heat exchanger is pressurized, the pressure during the drainage process can cause condensed acid to splash. Furthermore, the exact amount of condensed acid remaining in the heat exchanger cannot be accurately determined, making this method risky and impractical. Utility Model Content

[0003] The main objective of this invention is to provide a converter condensate acid collection box.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A converter condensate collection tank includes a main body, a gas inlet valve, a secondary suction tower connecting pipe, and a condensate discharge valve. A first, second, third, and fourth partition plate are fixedly connected to the inner side of the main body. The first and third partition plates are fixedly connected to the top wall of the main body, and the second and fourth partition plates are fixedly connected to the bottom wall of the fourth partition plate. The first, second, third, and fourth partition plates are staggered from left to right. The top of the fourth partition plate is at a lower height than the bottom of the third partition plate. Two level sensors are fixedly connected to the inner side of the main body.

[0006] A further improvement of this utility model is that an input distribution channel is formed between the first-section partition plate and the second-section partition plate, and a primary separation channel is formed between the first-section partition plate and the third-section partition plate.

[0007] A further improvement of this utility model is that a sinking flow channel is formed between the second-section partition plate and the third-section partition plate, and an output distribution flow channel is formed between the third-section partition plate and the fourth-section partition plate.

[0008] A further improvement of this utility model is that a tail temporary storage channel is formed between the four-section partition plate and the side wall of the main body of the box near the liquid level sensor.

[0009] A further improvement of this invention is that the two liquid level sensors are arranged symmetrically.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: After sulfur trioxide is transported to the interior of the main body of the tank through the gas inlet valve, it flows along the input distribution channel through the partition of the first-stage partition plate, and flows to the location of the first-stage separation channel after being intercepted by the second-stage partition plate. At this time, the sulfur trioxide is transported to the second suction tower through the suction tower connecting pipe, which can condense the acidic liquid in the gas in advance and recover it. Furthermore, the height difference formed by the first, second, third, and fourth partition plates is used to isolate the flow of acidic liquid, avoiding the incomplete precipitation of condensate in the condensed gas. After the tail temporary storage channel area is located and the liquid level sensor detects the acid position, the acid discharge valve performs the acid discharge operation without interfering with the operation of the heat exchanger, thereby achieving safe and reliable discharge and collection of condensed acid.

The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-2A converter condensate collection tank includes a main body 1, a gas inlet valve 2, a secondary suction tower connecting pipe 3, and a condensate discharge valve 4. A first-section partition plate 11, a second-section partition plate 12, a third-section partition plate 13, and a fourth-section partition plate 14 are fixedly connected to the inner side of the main body 1. The first-section partition plate 11 and the third-section partition plate 13 are fixedly connected to the top wall of the main body 1, and the second-section partition plate 12 and the fourth-section partition plate 14 are fixedly connected to the bottom wall of the fourth-section partition plate 14. The first-section partition plate 11, the second-section partition plate 12, the third-section partition plate 13, and the fourth-section partition plate 14 are staggered from left to right. The top of the fourth-section partition plate 14 is at a lower height than the bottom of the third-section partition plate 13. Two liquid level sensors 5 are fixedly connected to the inner side of the main body 1.

[0016] In this embodiment, an input distribution channel 101 is formed between a first-stage partition plate 11 and a second-stage partition plate 12, and a primary separation channel 102 is formed between a first-stage partition plate 11 and a third-stage partition plate 13.

[0017] In this embodiment, sulfur trioxide is delivered to the interior of the main body 1 of the tank via the gas inlet valve 2. It then flows along the input distribution channel 101 through the partition of the first-section partition plate 11 and flows to the location of the primary separation channel 102 after being intercepted by the second-section partition plate 12. At this time, the sulfur trioxide is delivered to the secondary absorption tower through the secondary absorption tower connecting pipe 3 corresponding to the area of ​​the primary separation channel 102. The condensed liquid is concentrated and deposited between the second-section partition plate 12 and the inner wall of the main body 1 of the tank.

[0018] In this embodiment, a sinking flow channel 103 is formed between the second-section partition plate 12 and the third-section partition plate 13, and an output distribution flow channel 104 is formed between the third-section partition plate 13 and the fourth-section partition plate 14.

[0019] In this embodiment, a tail temporary storage channel 105 is formed between the four-section partition plate 14 and the side wall of the main body 1 near the liquid level sensor 5.

[0020] In this embodiment, the two level sensors 5 are arranged symmetrically.

[0021] In this embodiment, a height difference is formed between the four-section partition plate 14 and the three-section partition plate 13, which can provide a certain flow isolation effect for the acidic liquid. This ensures that after the condensed gas is completely released from the condensate, it gradually flows to the area between the four-section partition plate 14 and the inner side of the main body 1. Until the area of ​​the tail temporary storage channel 105 is located above the liquid level sensor 5, which detects the position of the acid, the acid is discharged by the condensate discharge valve 4 (which is a solenoid valve), ensuring the stability of the condensate release.

[0022] The working principle of this utility model is as follows: After the condensed sulfur trioxide is transported to the interior of the main body 1 through the gas inlet valve 2, it flows along the input distribution channel 101 through the partition plate 11, and after being intercepted by the second partition plate 12, it flows to the location of the primary separation channel 102. At this time, the sulfur trioxide is transported to the secondary absorption tower through the secondary absorption tower connecting pipe 3 corresponding to the area of ​​the primary separation channel 102. This allows for the pre-condensation and recovery of acidic liquids in the gas. The condensate formed after condensation is stored at the bottom of the input distribution channel 101 until it submerges the second partition plate. After reaching a height of 12, the acidic liquid flows through the sinking channel 103 to the output distribution channel 104 and the tail temporary storage channel 105. The acidic liquid is isolated by the height difference formed by the first-stage partition plate 11, the second-stage partition plate 12, the third-stage partition plate 13 and the fourth-stage partition plate 14, which prevents the incomplete precipitation of condensate in the condensed gas. After the tail temporary storage channel 105 is located above the liquid level sensor 5, the acid is discharged by the condensate discharge valve 4 (a solenoid valve) without interfering with the operation of the heat exchanger, thus achieving safe and reliable discharge and collection of condensate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
