Description

Technical Field

[0001] The utility model relates to the technical field of sieve plate structures, in particular to a desulfurization liquid oxidation regeneration tower structure. Background Art

[0002] The desulfurization liquid oxidation regeneration tower is an important equipment in the desulfurization system. Its main function is to regenerate the desulfurization liquid so that it can be recycled. The sieve plate inside the desulfurization liquid oxidation regeneration tower plays a key role in preventing air bubbles from gradually merging into large bubbles. The design of the sieve plate allows the air entering the regeneration tower to be dispersed into smaller bubbles when passing through the sieve plate and mixed more fully with the desulfurization liquid. This can increase the gas-liquid contact area, improve mass transfer efficiency, and promote the occurrence of oxidation reactions.

[0003] In the prior art, a wet oxidation desulfurization device is proposed in a Chinese patent document with publication number CN219186441U. The application can drive a water pump to allow the desulfurization liquid to enter the water outlet pipe from the water inlet pipe, and finally spray out from the water spray holes of the spray plate. The cavity can balance the pressure of the desulfurization liquid, and the desulfurization liquid can be evenly distributed in the oxidation tank body through the water spray holes, thereby improving the oxidation efficiency. What is consistent with the prior art in the above patent document is that there is no adjustment structure for the aperture of the air passage hole on the sieve plate inside the tower body, resulting in that when the desulfurization liquid oxidation regeneration tower is working, the user can adjust the aperture of the air hole on the sieve plate according to the flue gas treatment effect at that time, causing the desulfurization liquid oxidation regeneration tower to reduce the purification effect when treating different flue gases. Furthermore, we disclose a desulfurization liquid oxidation regeneration tower structure to meet the actual demand for the flue gas purification effect. Summary of the invention

[0004] In view of this, the purpose of the utility model is to propose a desulfurization liquid oxidation regeneration tower structure to solve the problem that the sieve plate inside the tower body is not provided with an adjustment structure for the aperture of the air passage hole, which reduces the flue gas purification effect.

[0005] Based on the above-mentioned purpose, the utility model provides a desulfurization liquid oxidation regeneration tower structure, including a tower body, a sieve plate for preventing air bubbles from gradually merging into large bubbles is arranged inside the tower body, a plurality of second through holes for gas passage are evenly spaced on the surface of the sieve plate, an aperture adjustment component for accurately controlling the distribution and flow state of air in the tower body is arranged inside the sieve plate, the aperture adjustment component includes a plurality of expansion plates, a telescopic layer made of rubber material is fixedly connected between the plurality of expansion plates, the expansion plates are fan-shaped, the expansion plates are slidably connected to the inside of the sieve plate, a plurality of first through holes are evenly spaced on the surface of the expansion plate, and the aperture size of the first through holes is the same as that of the second through holes.

[0006] Preferably, a plurality of the sieve plates are provided inside with pentagonal plates, and the pentagonal plates are fixedly connected to the sieve plates.

[0008] Preferably, the top plate is designed to be arc-shaped, and an outer wall of the top plate on one side away from the sliding rod is fixedly connected to the expansion plate.

[0009] Preferably, a connecting disk is rotatably engaged in the middle of the lower end of the pentagonal plate, and a plurality of waist-shaped grooves are evenly spaced on the surface of the connecting disk. The waist-shaped grooves are arc-shaped in design, and a card shaft is slidably engaged inside the waist-shaped grooves, and the upper end of the card shaft is fixedly connected to the sliding rod.

[0010] Preferably, a fixing rod is fixedly connected to the middle of the lower end surface of the connecting plate, a driven bevel gear is fixedly connected to the lower end of the fixing rod, a driving bevel gear is meshedly connected to one side of the lower end of the driven bevel gear, and a rotating shaft is fixedly connected to one side end surface of the driving bevel gear.

[0012] Preferably, a glass is fixedly connected to one side of the outer wall of the tower body near the upper end for facilitating users to see the internal working conditions clearly.

[0013] The beneficial effects of the utility model are as follows: an adjustment structure for the aperture of the air passage hole is arranged on the sieve plate inside the tower body. Under normal circumstances, the first through hole on the expansion plate is coaxial with the first through hole on the sieve plate. When the user needs to make adjustments according to the internal flue gas treatment conditions, the multiple expansion plates are driven to expand outward by turning the knob, and the first through hole liquid on the expansion plate moves, causing the first through hole to deviate from the second through hole. The expansion plate blocks the second through hole, thereby completing the adjustment of the aperture of the air passage hole on the sieve plate. Through this structural design, it can be ensured that the flue gas remains in the form of fine bubbles, the gas-liquid contact area is increased, the mass transfer rate is improved, and the purification effect is increased.

Under normal circumstances, the first through hole 15 on the expansion plate 7 is coaxial with the first through hole 15 on the sieve plate 6. When the user needs to make adjustments according to the internal flue gas treatment conditions, the multiple expansion plates 7 are driven to expand outward by turning the knob, and the liquid in the first through hole 15 on the expansion plate 7 moves, so that the first through hole 15 deviates from the second through hole 16. The expansion plate 7 blocks the second through hole 16, thereby completing the adjustment of the aperture of the air passage on the sieve plate 6. Through this structural design, it can be ensured that the flue gas remains in the form of fine bubbles, the gas-liquid contact area is increased, the mass transfer rate is improved, and the purification effect is increased.

[0025] Further, such as Figures 1 to 5As shown, a plurality of sieve plates 6 are provided with pentagonal plates 11 inside, the pentagonal plates 11 are fixedly connected to the sieve plates 6, a plurality of slide bars 17 are slidably connected to the outer side of the pentagonal plates 11, the number of the slide bars 17 is the same as the number of the expansion plates 7, the end face of the slide bar 17 away from the pentagonal plates 11 is fixedly connected to the top plate 9, the top plate 9 is of arc design, the outer wall of the top plate 9 away from the slide bar 17 is fixedly connected to the expansion plate 7, the middle part of the lower end of the pentagonal plates 11 is engaged and rotatably connected to the connecting disk 12, the surface of the connecting disk 12 is evenly spaced with a plurality of waist-shaped grooves 13, the waist-shaped grooves 13 are of arc design, and the waist-shaped grooves 13 are of arc design.

In actual use, a gear that meshes with the outer wall of the connecting disk 12 can be arranged.

[0026] Working principle: When the user needs to adjust according to the internal smoke treatment situation, first turn the rotating rod through the knob, the rotating rod drives the active bevel gear 4 to rotate, the active bevel gear 4 drives the driven bevel gear 5 to rotate, and then drives the connecting plate 12 to rotate through the fixing rod 14. Since the pentagonal plate 11 is fixedly connected to the sieve plate 6, when the connecting plate 12 rotates, the limiting effect of the waist groove 13 makes the card shaft 10 slide inside the waist groove 13, so that the card shaft 10 drives the slide rod 17 to slide on the pentagonal plate 11, and the slide rod 17 slides to drive the top Plate 9 expands outward, and the expansion of top plate 9 drives expansion plate 7 to expand, thereby completing the adjustment of the aperture of the air passage hole on sieve plate 6.
