Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a waste gas absorption device for sponge zirconium crushing. Background Technology

[0002] Sponge zirconium is an important raw material in the nuclear industry and special metallurgy. During its crushing and processing, it generates a large amount of waste gas containing metal dust and trace amounts of harmful components such as chlorides and hydrogen chloride. Direct emission of this waste gas will cause air pollution and endanger the health of workers. Therefore, it is necessary to absorb and purify this type of waste gas. Most existing waste gas absorption devices absorb waste gas through spray towers, using the absorbent liquid to come into countercurrent contact with the waste gas, so that the dust and harmful components in the waste gas are dissolved or captured, thereby achieving waste gas purification.

[0003] In the prior art, when the spray system is shut down or the spray pressure is insufficient, dust in the sponge zirconium exhaust gas can easily enter the spray holes, causing blockage and affecting the continuous operation capability and maintenance cost of the device. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore: The first aspect of this utility model proposes a waste gas absorption device for sponge zirconium crushing, including an absorption tank, a sealing cover, a spray assembly, and a protective assembly. The sealing cover is fixed to the upper end of the absorption tank; the spray assembly includes a spray pipe, which is fixed to the sealing cover, with one end of the spray pipe extending into the interior of the absorption tank, and the pipe wall inside the absorption tank has a plurality of spray holes spaced apart along the axial direction; the protective assembly includes a sleeve and a plurality of protective blocks, the sleeve being rotatably connected to the absorption tank and coaxially sleeved on the outer wall of the spray pipe; the plurality of protective blocks are fixed to the sleeve at intervals along the circumference of the sleeve and extend downward along the axial direction of the spray pipe; wherein, when the protective block rotates relative to the spray pipe to a first position, the protective block closes the spray holes; when the protective block rotates relative to the spray pipe to a second position, the protective block avoids the spray holes.

[0006] This utility model proposes a waste gas absorption device for sponge zirconium crushing. The waste gas enters from the bottom of the absorption tank and flows upward. The absorbent liquid is sprayed out from the spray holes through the spray pipe and comes into contact with the waste gas to absorb dust and harmful components in the waste gas. When the device is stopped or the spray system needs to be protected, the sleeve drives several protective blocks to rotate to the first position, so that the protective blocks block the spray holes and prevent dust from entering the holes and causing blockage. When the operation resumes, the sleeve rotates in the opposite direction, so that the protective blocks rotate to the second position to avoid the spray holes and the spray holes resume normal spraying, thereby realizing switchable protection of the spray holes and ensuring long-term stable operation of the device.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0011] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

The sealing cover 200 is fixed to the upper end of the absorption tank 100. The spray assembly 300 includes a spray pipe 310, which is fixed to the sealing cover 200. One end of the spray pipe 310 extends into the interior of the absorption tank 100, and the pipe wall inside the absorption tank 100 is provided with a plurality of spray holes 320 spaced apart along the axial direction. The protective assembly 400 includes a sleeve. The sleeve 410 is rotatably connected to the absorption tank 100 and coaxially sleeved on the outer wall of the spray pipe 310. The sleeve 410 is fixed to the sleeve 410 at intervals along the circumference and extends downward along the axis of the spray pipe 310. When the sleeve 420 rotates relative to the spray pipe 310 to the first position, the sleeve 420 closes the spray hole 320. When the sleeve 420 rotates relative to the spray pipe 310 to the second position, the sleeve 420 avoids the spray hole 320.

[0013] In this embodiment: The sealing cover 200 is fixed to the upper end of the absorption tank 100; it is used to seal the top opening of the absorption tank 100 to prevent the exhaust gas from leaking out.

[0014] The spray pipe 310 is fixed to the sealing cover 200. One end of the spray pipe 310 extends into the interior of the absorption tank 100, and the pipe wall inside the absorption tank 100 is provided with a number of spray holes 320 at intervals along the axial direction. The absorbent liquid is evenly sprayed into the absorption tank 100 through the number of spray holes 320 to form a multi-layer spray curtain, which increases the contact time between the absorbent liquid and the waste gas and improves the absorption efficiency.

[0015] The sleeve 410 is rotatably connected to the absorption tank 100 and coaxially sleeved on the outer wall of the spray pipe 310; the sleeve 410 can rotate around the axis of the spray pipe 310 to provide rotational support for the protective block 420.

[0016] Several protective blocks 420 are fixed to the sleeve 410 at intervals along the circumference of the sleeve 410 and extend downward along the axis of the spray pipe 310. When the sleeve 410 rotates, it drives the several protective blocks 420 to rotate synchronously around the axis of the spray pipe 310, so that the protective blocks 420 switch between the first position of shielding the spray hole 320 and the second position of avoiding the spray hole 320, thereby realizing the opening and closing of the spray hole 320.

[0017] When the protective block 420 rotates relative to the spray pipe 310 to the first position, the protective block 420 closes the spray hole 320; when the protective block 420 rotates relative to the spray pipe 310 to the second position, the protective block 420 avoids the spray hole 320; when the protective block 420 rotates relative to the spray pipe 310 to the first position, the protective block 420 covers all the spray holes 320 along the axial direction of the spray pipe 310 to close the spray holes 320; when the protective block 420 rotates relative to the spray pipe 310 to the second position, the protective block 420 and each spray hole 320 are offset from each other along the circumference of the spray pipe 310, and the protective block 420 avoids the spray hole 320.

[0018] Please see Figure 5 In some embodiments of this utility model, the protective component 400 further includes a drive motor 430, a drive gear 440, and a driven gear 450. The drive motor 430 is fixed to the sealing cover 200, and the output shaft of the drive motor 430 extends into the interior of the sealing cover 200. The drive gear 440 is fixed to the output shaft of the drive motor 430. The driven gear 450 is fixed to the outer wall of the sleeve 410, and the driven gear 450 meshes with the drive gear 440.

[0019] In this embodiment: The drive motor 430 is fixed to the sealing cover 200, and the output shaft of the drive motor 430 extends into the interior of the sealing cover 200.

[0020] The drive gear 440 is fixed to the output shaft of the drive motor 430; the drive gear 440 rotates synchronously with the output shaft of the drive motor 430.

[0021] Driven gear 450 is fixed to the outer wall of sleeve 410, and driven gear 450 meshes with driving gear 440. When drive motor 430 is running, driving gear 440 drives driven gear 450 and sleeve 410 to rotate, thereby driving protective block 420 to rotate. By controlling the direction and angle of drive motor 430, the spray hole 320 can be closed and avoided.

[0022] Please see Figure 2 In some embodiments of this utility model, the waste gas absorption device for sponge zirconium crushing further includes a circulation component 500, which includes a water pump 510, a filter 520, an inlet pipe 530, and an outlet pipe 540.

The filter 520 is connected in series with the inlet pipe 530. The absorption liquid accumulated at the bottom of the absorption tank 100 flows through the inlet pipe 530 to the filter 520 under the suction of the water pump 510, and enters the water pump 510 after filtration.

[0026] The two ends of the outlet pipe 540 are connected to the outlet of the water pump 510 and the spray pipe 310, respectively. The absorbent liquid is transported to the spray pipe 310 through the outlet pipe 540 and sprayed out through the spray hole 320, thus completing the recycling of the absorbent liquid and reducing the consumption of absorbent liquid and operating costs.
