Description

Technical Field

[0001] The utility model belongs to the technical field of separation devices, and in particular relates to a chlorine gas demister. Background Art

[0002] As one of the main products of the chlor-alkali industry, chlorine has the ability to undergo substitution and addition reactions with organic and inorganic substances to generate a variety of chlorides, and can also act as a strong oxidant. Chlorine is mainly used in the production of plastics, synthetic fibers, dyes, pesticides, disinfectants, bleaches and various chlorides.

[0003] Demisters are widely used gas-liquid two-phase separation devices in industrial production. In the chlor-alkali process, it is necessary to separate the tiny droplets mixed in the chlorine gas. Due to the extremely small size of these droplets, the separation work is difficult in actual industrial operations. In order to effectively remove the droplets carried in the gas, industrial production usually uses demisters to treat industrial exhaust gases. According to the structure and principle of the demister, it can be divided into many types, such as shutter separators, gravity sedimentation separators, cyclone plate separators, and wire mesh demisters. However, these traditional separators generally have the problem of low separation efficiency, and it is difficult to achieve effective separation for droplets with smaller particle sizes. Utility Model Content

[0004] The utility model aims to provide a chlorine demister, which can significantly improve the separation efficiency of tiny droplets in chlorine, thereby improving the effect and quality of chlorine purification in the production process of chlor-alkali industry, and reducing the adverse effects of droplet entrainment on subsequent processes and product quality.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] The chlorine demister comprises a shell, a plurality of groups of tower plates are arranged inside the shell, a plurality of groups of corrugated plate assemblies are arranged through the tower plates, the corrugated plate assemblies comprise a front corrugated plate and a rear corrugated plate, the front corrugated plate comprises an upper folding plate 1, the bottom end of which is sequentially connected to a middle folding plate 1 and a lower folding plate 1, the rear corrugated plate comprises an upper folding plate 2, the bottom end of which is sequentially connected to a middle folding plate 2 and a lower folding plate 2, the upper folding plate 2, the middle folding plate 2 and the lower folding plate 2 are respectively arranged in conjunction with the upper folding plate 1, the middle folding plate 1 and the lower folding plate 1, a connecting plate is arranged between the front corrugated plate and the rear corrugated plate, and the distance between the upper folding plate 1 and the upper folding plate 2 is smaller than the distance between the lower folding plate 1 and the lower folding plate 2.

[0007] in:

[0008] The distance between the upper folding plate 1 and the upper folding plate 2 is smaller than the distance between the middle folding plate 1 and the middle folding plate 2, and the distance between the middle folding plate 1 and the middle folding plate 2 is smaller than the distance between the lower folding plate 1 and the lower folding plate 2.

[0009] The bottoms of the several groups of tower plates are all equipped with downcomers.

[0010] A downcomer main pipe is arranged inside the shell, one end of which is connected to the downcomer at the bottom of the topmost tower plate, and the other end of which penetrates the bottommost tower plate and extends to the bottom of the shell.

[0011] One end of the downcomer is connected to the tower plate, and the other end of the downcomer is connected to the downcomer main pipe.

[0012] The tower plate is provided with an air riser in coordination with the corrugated plate assembly.

[0013] The riser is provided with a protective cover.

[0014] The bottom of the shell is provided with a liquid outlet pipe.

[0015] A chlorine gas outlet pipe is arranged on the top of the shell.

[0016] A chlorine gas inlet pipe is arranged on one side of the shell, one end of the chlorine gas inlet pipe extends into the interior of the shell and the chlorine gas inlet pipe is located below the bottommost tower plate.

[0017] The beneficial effects of the utility model are:

[0018] When chlorine gas flows through the corrugated plate assembly, the mist droplets in the chlorine gas collide with the corrugated plate assembly and gather, which can effectively improve the separation efficiency; the corrugated plate assembly can change the flow direction of the chlorine gas multiple times, so that the mist droplets in the chlorine gas can be removed more thoroughly, greatly improving the demisting efficiency; the distance between the upper folding plate 1 and the upper folding plate 2 is smaller than the distance between the lower folding plate 1 and the lower folding plate 2. In the process of chlorine gas flowing through the corrugated plate assembly, as the distance between the front corrugated plate and the rear corrugated plate becomes smaller, the probability of the mist droplets in the chlorine gas colliding with each other increases, which promotes the aggregation of the mist droplets and provides a more spacious diversion space for the captured mist droplets, thereby preventing the captured mist droplets from clogging the corrugated plate assembly.

[0025] The utility model is described and illustrated in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, the chlorine demister of the utility model comprises a shell 1, a plurality of tower plates 2 are arranged inside the shell 1, a plurality of corrugated plate assemblies 3 are arranged through the tower plates 2, the corrugated plate assemblies 3 comprise a front corrugated plate 301 and a rear corrugated plate 302, the front corrugated plate 301 comprises an upper folding plate 1 3011, the bottom end of the upper folding plate 1 3011 is sequentially connected to a middle folding plate 1 3012 and a lower folding plate 1 3013, the rear corrugated plate 302 comprises an upper folding plate 2 3021, the bottom end of the upper folding plate 2 302 ... The ends are connected in sequence with the middle folding plate 2 3022 and the lower folding plate 2 3023, the upper folding plate 2 3021, the middle folding plate 2 3022 and the lower folding plate 2 3023 are respectively matched with the upper folding plate 1 3011, the middle folding plate 1 3012 and the lower folding plate 1 3013, a connecting plate 303 is arranged between the front corrugated plate 301 and the rear corrugated plate 302, and the distance between the upper folding plate 1 3011 and the upper folding plate 2 3021 is smaller than the distance between the lower folding plate 1 3013 and the lower folding plate 2 3023.

[0028] When chlorine gas flows through the corrugated plate assembly 3, the mist droplets in the chlorine gas collide with the corrugated plate assembly 3 and gather, which can effectively improve the separation efficiency; the corrugated plate assembly 3 can change the flow direction of the chlorine gas multiple times, so that the mist droplets in the chlorine gas can be removed more thoroughly, greatly improving the demisting efficiency; the distance between the upper folding plate 1 3011 and the upper folding plate 2 3021 is smaller than the distance between the lower folding plate 1 3013 and the lower folding plate 2 3023. In the process of chlorine gas flowing through the corrugated plate assembly 3, as the distance between the front corrugated plate 301 and the rear corrugated plate 302 gradually decreases, the probability of the mist droplets in the chlorine gas colliding with each other increases, which promotes the aggregation of the mist droplets and provides a more spacious diversion space for the captured mist droplets to avoid the captured mist droplets clogging the corrugated plate assembly 3.

[0029] The distance between the upper folding plate 1 3011 and the upper folding plate 2 3021 is smaller than the distance between the middle folding plate 1 3012 and the middle folding plate 2 3022 , and the distance between the middle folding plate 1 3012 and the middle folding plate 2 3022 is smaller than the distance between the lower folding plate 1 3013 and the lower folding plate 2 3023 .

[0032] One end of the downcomer 4 is connected to the tower plate 2, and the other end of the downcomer 4 is connected to the downcomer main pipe 5. The downcomer main pipe 5 can collect the mist droplets flowing out from the tower plates 2 of each layer and discharge them in a centralized manner.

[0033] The tower plate 2 is provided with a riser 6 in cooperation with the corrugated plate assembly 3. The riser 6 can make the chlorine gas rise from the lower tower plate 2 to the upper tower plate 2, so as to ensure that the chlorine gas flows in the shell 1 in an orderly manner.

The protective cover 7 can prevent mist droplets from falling into the riser 6, prevent mist droplets from being entrained by chlorine gas, and affect the demisting effect, and prevent foreign matter from falling into the riser 6, ensuring that the riser 6 is unobstructed.

[0035] A liquid outlet pipe 8 is provided at the bottom of the housing 1. The liquid outlet pipe 8 discharges the mist droplets collected at the bottom of the housing 1 to prevent the mist droplets from accumulating at the bottom of the housing 1.

[0036] A chlorine gas outlet pipe 9 is provided on the top of the housing 1. The chlorine gas after demisting can be discharged through the chlorine gas outlet pipe 9, so that the demisted chlorine gas can smoothly enter the subsequent process flow.
