Description

Technical Field

[0001] This utility model relates to the technical field of sulfide production equipment, and in particular to a demisting device and a desulfurization tower. Background Technology

[0002] Currently, in the chemical reagent production process, demisters are used to remove moisture from the reaction gas. When the gas containing mist flows through the demister at a certain speed, the mist in the gas collides with the corrugated plate, and the mist is gathered into droplets, which are then separated from the gas, thus removing the moisture.

[0003] In related technologies, after the mist on the corrugated plate gathers into droplets, it drips back into the desulfurization tower under the action of gravity, which is not only inconvenient to clean, but also wastes water resources. Summary of the Invention

[0004] The main purpose of this invention is to provide a defogging device that collects water droplets gathered on a corrugated plate to reduce water resource consumption.

[0005] To achieve the above objectives, the present invention provides a defogging device comprising:

[0006] The mounting housing has a defogging chamber and an air inlet and an air outlet that connect to the defogging chamber.

[0007] An annular water storage tank, wherein the annular water storage tank is arranged around the air inlet; and

[0008] Multiple corrugated plates are spaced apart within the demisting air chamber. Each corrugated plate includes a plate body and water-blocking ribs connected to the edge of the plate body. The plate body is located above the annular water storage tank, and the water-blocking ribs are located at the lower part of the plate body and are inclined towards the annular water storage tank.

[0009] In an alternative embodiment, the water-blocking ribs are inclined from one side of the symmetry axis of the corrugated plate toward the opposite sides of the plate body.

[0010] In an optional embodiment, the cross-section of the water-blocking rib is elliptical.

[0011] In an optional embodiment, the annular water storage tank includes a tank body and a floating switch valve, the tank body having a drain outlet, and the floating switch valve being disposed at the drain outlet.

[0012] In an optional embodiment, the corrugated plate is made of fiberglass.

[0013] This utility model also proposes a desulfurization tower, including a tower body, a spraying device and a demisting device, wherein the demisting device is the demisting device described above, and the tower body forms a reaction chamber and an air inlet channel and an air outlet channel communicating with the reaction chamber.

[0014] The demisting device includes a mounting housing, an annular water storage tank, and multiple corrugated plates. The mounting housing is installed inside the reaction chamber and forms a demisting air chamber and an air inlet and an air outlet communicating with the demisting air chamber. The annular water storage tank is arranged around the air inlet. The multiple corrugated plates are spaced apart inside the demisting air chamber. Each corrugated plate includes a plate body and water-blocking ribs connected to the edge of the plate body. The plate body is located above the annular water storage tank, and the water-blocking ribs are located at the lower part of the plate body and are inclined towards the side facing the annular water storage tank.

[0015] The spraying device is installed inside the reaction chamber and located below the multiple corrugated plates. The spraying device is connected to the annular water storage tank through a pipeline.

[0016] In an optional embodiment, the spray device includes a plurality of spray heads disposed below the corrugated plate and evenly spaced circumferentially along the central axis of the air inlet.

[0017] In an optional embodiment, the desulfurization tower further includes a limiting installation frame, which is installed in the reaction chamber and forms a limiting groove, and the mounting shell is snapped into the limiting installation frame.

[0018] In an optional embodiment, the desulfurization tower further includes an annular air guide plate, which is connected to the limiting mounting frame and is arranged in a flared shape facing the air outlet channel.

[0019] This utility model's technical solution employs an installation housing that forms a demisting air chamber and an air inlet and outlet connecting to it. Gas containing mist enters the demisting air chamber through the air inlet and flows out through the air outlet. An annular water storage tank is arranged around the air inlet, and multiple corrugated plates are spaced apart within the demisting air chamber. Each corrugated plate includes a plate body and water-blocking ribs connected to the edge of the plate body. The plate body is located above the annular water storage tank. The plate body is used to block the mist in the gas and cause it to accumulate on the plate body. When the accumulated water droplets flow downwards, the water-blocking ribs will stop them. Since the water-blocking ribs are located above the water storage tank and tilted towards one side of the water storage tank, the water droplets will flow into the water storage tank along the extension direction of the water-blocking ribs. This not only prevents water droplets from dripping back into the desulfurization tower, making it easier for staff to clean the desulfurization tower, but also collects water droplets in the water storage tank for recycling, thus greatly reducing water resource consumption.

[0034] Reference Figures 1 to 7 This utility model proposes a defogging device 10.

[0035] In this embodiment of the utility model, the defogging device 10 includes:

[0036] Mounting housing 11, the mounting housing 11 forming a demisting air chamber 11a and an air inlet 11b and an air outlet 11c communicating with the demisting air chamber 11a; an annular water storage tank 12, the annular water storage tank 12 being arranged around the air inlet 11b; and

[0037] Multiple corrugated plates 13 are spaced apart within the demisting air chamber 11a. Each corrugated plate 13 includes a plate body 131 and a water-blocking rib 132 connected to the edge of the plate body 131. The plate body 131 is located above the annular water storage tank 12, and the water-blocking rib 132 is located at the lower part of the plate body 131 and is inclined towards the side facing the annular water storage tank 12.

[0038] Specifically, in this application, the mounting housing 11 can be formed from sheet metal or plastic material, and its overall shape can be a cylindrical, polygonal, or other shell-like structure, which can be set according to needs. In this embodiment, the mounting housing 11 is cylindrical to adapt to the shape of the desulfurization tower 100. The mounting housing 11 forms a circular demisting air chamber 11a and an air inlet 11b and an air outlet 11c that connect the demisting air chamber 11a. The annular water storage tank 12 is set at the air inlet 11b by screws or other structures, that is, the annular water storage tank 12 also defines the annular air inlet 11b.

[0039] The corrugated plate 13 includes a plate body 131 and water-retaining ribs 132. The plate body 131 can be formed by bending sheet metal or plastic material. In this application, the plate body 131 is preferably made of fiberglass, which has high strength and corrosion resistance, and can improve the service life of the demisting device 10. The water-retaining ribs 132 and the plate body 131 can be integrally formed, or the water-retaining ribs 132 can be connected to the plate body 131 by means of adhesive bonding or screw fixing.

[0040] In this invention, gas containing mist enters the demisting chamber 11a through the air inlet 11b and flows out of the demisting chamber 11a through the air outlet 11c. The plate 131 of the corrugated plate 13 is used to block the mist in the gas and cause it to accumulate on the plate 131. When the accumulated water droplets flow downward, the water-blocking rib 132 will stop them. Since the water-blocking rib 132 is located above the water storage tank and is inclined towards the water storage tank, the water droplets will flow into the water storage tank along the extension direction of the water-blocking rib 132. This can prevent water droplets from dripping back into the desulfurization tower 100, making it easier for staff to clean the desulfurization tower 100. On the other hand, the water droplets are collected in the water storage tank and recycled, thus greatly reducing the loss of water resources.

[0041] Furthermore, in this embodiment, the water-blocking ribs 132 are inclined from one side of the symmetry axis of the corrugated plate 13 towards the opposite sides of the plate body 131. That is, the water-blocking ribs 132 are inclined downwards towards the opposite sides of the plate body 131, so that the extension trajectory of the water-blocking ribs 132 presents a triangle facing upwards towards the plate body 131. This arrangement can minimize the path of water droplet flow, allowing water droplets to flow into the annular water storage tank 12 as quickly as possible, avoiding accumulation during the flow process and dripping into the desulfurization tower 100.

[0042] Please see again Figure 3 and Figure 4 In this application, the water-blocking rib 132 is integrally formed with the plate 131, and the cross-section of the water-blocking rib 132 is elliptical. Specifically, the cross-section of the water-blocking rib 132 resembles the airfoil of an aircraft wing. Setting its cross-section to elliptical is more in line with aerodynamics. When airflow passes through the water-blocking rib 132, the airflow can flow more closely to the surface of the plate 131, allowing the mist droplets to come into more full contact with the plate 131, thereby improving the defogging effect.

[0043] The annular water storage tank 12 includes a tank body 121 and a floating valve 122. The tank body 121 has a drain outlet, and the floating valve 122 is located at the drain outlet. When no water enters, the floating valve 122 blocks the drain outlet under its own weight. When water enters the tank body 121, the floating valve 122 floats upwards due to buoyancy, thereby discharging the water from the tank body 121 through the drain outlet. In this application, the drain outlet is connected to the spray head 31 of the desulfurization tower 100 via a pipeline to achieve water resource recycling.

[0044] Please see again Figures 1 to 5 This utility model also proposes a desulfurization tower 100, which includes a tower body 20, a spray device 30, and a demisting device 10. The specific structure of the demisting device 10 is as described in the above embodiments. Since the desulfurization tower 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The tower body 20 is a cylindrical shell cavity structure, forming a reaction chamber 20c and an air inlet channel 20a and an air outlet channel 20b connecting the reaction chamber 20c. The demisting device 10 includes a mounting shell 11, an annular water storage tank 12, and multiple corrugated plates 13. The mounting shell 11 is installed inside the reaction chamber 20c and forms a demisting air chamber 11a and an air inlet 11b and an air outlet 11c connecting the demisting air chamber 11a. The annular water storage tank 12 is arranged around the air inlet 11b. Multiple corrugated plates 13 are spaced apart in the demisting air chamber 11a. Each corrugated plate 13 includes a plate body 131 and a water-blocking rib 132 connected to the edge of the plate body 131. The plate body 131 is located above the annular water storage tank 12, and the water-blocking rib 132 is located at the lower part of the plate body 131 and is inclined towards the side facing the annular water storage tank 12. A spray device 30 is installed in the reaction chamber 20c and is located below the multiple corrugated plates 13. The spray device 30 is connected to the annular water storage tank 12 through a pipeline.

[0045] In this application, the chemical gas to be desulfurized enters the reaction chamber 20c through the air inlet channel 20a. As it flows toward the air outlet channel 20b, the spray device 30 sprays water onto the chemical gas to remove the sulfides. The chemical gas containing water vapor flows to the demisting device 10, where the demisting device 10 removes the mist. The dried gas then flows to the next stage through the mist outlet channel.

[0046] In this embodiment, the spray device 30 includes multiple spray heads 31, which are disposed below the corrugated plate 13 and are evenly spaced around the central axis of the air inlet 11b. That is, the trajectory line formed by the connection of multiple spray heads 31 is circular. This not only avoids the air inlet 11b, but also maximizes the spraying of desulfurized gas, thereby improving the desulfurization effect of the gas.

[0047] In this embodiment, the desulfurization tower 100 also includes a limiting installation frame 40, which is installed inside the reaction chamber 20c and forms a limiting groove 40a. The mounting housing 11 is snapped into the limiting installation frame 40. This makes the assembly and disassembly of the demisting device 10 more convenient.

[0048] Furthermore, the desulfurization tower 100 also includes an annular air guide plate 50, which is connected to the limiting mounting frame 40 and is flared outwards towards the air outlet channel 20b. In this application, the annular air guide plate 50 and the limiting mounting frame 40 are integrally formed. By setting the annular air guide plate 50, the flow velocity of the chemical gas can be further increased, thereby improving the desulfurization efficiency of the desulfurization tower 100.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
