Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a desulfurization device for industrial waste gas purification. Background Technology

[0002] Industrial waste gas purification is an important part of reducing pollutant emissions and protecting the environment during industrial production. Desulfurization devices in industrial waste gas purification are mainly used to remove sulfur oxides (SO2, SO3) from waste gas, especially high-sulfur flue gas emitted by coal-fired power plants, steel smelting, petrochemical and other industries.

[0003] Traditional industrial waste gas desulfurization devices have the following shortcomings: In operation, these devices typically employ wet desulfurization, utilizing alkaline absorbents (such as limestone slurry or ammonia) to react chemically with SO2 in the flue gas, producing sulfates or sulfites. In the wet desulfurization spray tower, when the high-temperature flue gas comes into contact with the low-temperature spray slurry, some water evaporates, forming water vapor. Simultaneously, the flue gas itself may contain a certain amount of humidity, especially under conditions of insufficient pre-cooling, resulting in higher water vapor content. When this water vapor condenses on the spray head surface, it carries the aforementioned impurities, forming a viscous mixture that gradually deposits on the spray head surface or the inner wall of the spray holes. Long-term accumulation can lead to the shrinkage or even complete blockage of the spray holes, affecting spray uniformity and desulfurization efficiency. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a desulfurization device for industrial waste gas purification, which has the advantage of reducing maintenance frequency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization device for industrial waste gas purification, comprising a desulfurization device, a filter device disposed on the right side of the desulfurization device, the desulfurization device comprising a spray tower body, a spray device disposed inside the spray tower body, the spray device comprising a first spray pipe welded to the inner side of the spray tower body, second spray pipes welded to both sides of the first spray pipe, mounting heads uniformly threaded below the first and second spray pipes, a sprayer welded below the mounting head, an arc-shaped groove formed at the bottom of the sprayer, an atomizing nozzle disposed on the surface of the arc-shaped groove, and the mounting head below the second spray pipe deflected toward the side closer to the inner wall of the spray tower body.

[0006] As a preferred technical solution of this utility model, a bottom ring block located outside the mounting head is welded to the bottom of both the first and second spray pipes. A connecting block is uniformly welded to the bottom of the bottom ring block. An outer ring block located outside the connecting block is welded to the bottom of the bottom ring block. An elastic ring is glued to the bottom of the connecting block. A threaded groove is opened on the inner side of the outer ring block. A threaded ring is threaded on the inner side of the threaded groove. A triangular retaining ring is welded to the bottom of the threaded ring.

[0007] As a preferred embodiment of this utility model, an air inlet pipe is provided on the left side of the spray tower body, a water outlet is provided on the right side of the bottom end of the spray tower body, and an air outlet pipe is provided on the top of the spray tower body.

[0008] As a preferred embodiment of this utility model, the filtration device includes a filter box located on the right side of the spray tower body. A connecting pipe is bolted to the left end of the filter box, and the other end of the connecting pipe is bolted to the inside of the water outlet. A water tank is bolted to the top of the filter box, and an installation pipe is threaded onto the top of the water tank. The other end of the installation pipe is threaded onto the right end of the spray pipe.

[0009] As a preferred embodiment of this utility model, an activated carbon adsorption layer is installed inside the spray tower body by bolts, and the activated carbon adsorption layer is located above the spraying device.

[0010] As a preferred embodiment of this utility model, a knob is welded above the threaded ring, and the knob is located above the outer ring block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model creates an arc-shaped groove at the bottom of the sprayer, allowing water mist to form small water droplets under gravity and move along the groove towards the edge of the sprayer. Compared with traditional desulfurization devices for industrial waste gas purification, this desulfurization device effectively reduces the amount of water droplets around the atomizing nozzle, thereby reducing the clogging of the atomizing nozzle by viscous mixtures, reducing the frequency of sprayer maintenance, and making it easier to use.

[0013] 2. This utility model uses an elastic ring to clamp the surface of the mounting head. When the sprayer needs to be disassembled, simply rotate the knob to disengage the elastic ring from the surface of the mounting head, and then remove the sprayer. Compared with traditional desulfurization devices for industrial waste gas purification, this desulfurization device seals the connection between the mounting head and the spray pipe with an elastic ring, preventing water vapor from entering the connection gap and causing it to rust and age, thereby improving the service life of the sprayer and the spray pipe.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6As shown, this utility model provides a desulfurization device for industrial waste gas purification, including a desulfurization device 1, a filter device 2 arranged on the right side of the desulfurization device 1, a spray tower body 11, a spray device 3 arranged inside the spray tower body 11, a spray pipe 301 welded to the inner side of the spray tower body 11, a second spray pipe 302 welded to both sides of the first spray pipe 301, an installation head 303 evenly threaded below the first spray pipe 301 and the second spray pipe 302, a sprayer 304 welded below the installation head 303, an arc-shaped groove 305 opened at the bottom of the sprayer 304, an atomizing nozzle 306 arranged on the surface of the arc-shaped groove 305, and the installation head 303 below the second spray pipe 302 deflected to the side closer to the inner wall of the spray tower body 11.

[0023] The spray tower body 11 has an air inlet pipe 12 on its left side, a water outlet 15 on the right side of its bottom end, and an air outlet pipe 14 on its top. The filter device 2 includes a filter box 21 located on the right side of the spray tower body 11. A connecting pipe 22 is bolted to the left end of the filter box 21, and the other end of the connecting pipe 22 is bolted to the inside of the water outlet 15. A water tank 23 is bolted to the top of the filter box 21, and an installation pipe 24 is threaded to the top of the water tank 23. The other end of the installation pipe 24 is threaded to the right end of the spray pipe 301. An activated carbon adsorption layer 13 is bolted inside the spray tower body 11 and is located above the spray device 3.

[0024] In use, the alkaline absorbent is introduced to the bottom of the spray tower 11, and then exhaust gas is introduced into the spray tower 11 through the air inlet pipe 12. At this time, the water tank 23 injects the alkaline absorbent into the interior of the first spray pipe 301 through the installation pipe 24 via the built-in water pump. The exhaust gas in the spray tower 11 is sprayed by the sprayers 304 below the first spray pipe 301 and the second spray pipe 302, causing the alkaline absorbent to react with the sulfides and fall into the alkaline absorbent at the bottom of the spray tower 11. After passing through the filter box, the exhaust gas is then removed. The water pump inside 21 draws the alkaline absorbent from the bottom of the spray tower 11 into the filter box 21 for filtration. Then, the water pump inside the water tank 23 draws the filtered alkaline absorbent from the filter box 21 into the water tank 23. The water is then circulated through the installation pipe 24. When water vapor adheres to the surface of the sprayer 304, it is caused by gravity to form small water droplets that move along the arc groove 305 towards the edge of the sprayer 304, thereby reducing the number of water droplets around the atomizing nozzle 306.

[0025] By creating an arc-shaped groove 305 at the bottom of the sprayer 304, water mist forms small water droplets under the influence of gravity and moves along the arc-shaped groove 305 towards the edge of the sprayer 304. Compared with traditional desulfurization devices for industrial waste gas purification, this desulfurization device for industrial waste gas purification effectively reduces the number of water droplets around the atomizing nozzle 306, thereby reducing the clogging of the atomizing nozzle 306 by viscous mixtures, reducing the maintenance frequency of the sprayer 304, and making it easier to use.

[0026] Below both spray pipe 301 and spray pipe 302, a bottom ring block 308 is welded to the outside of the mounting head 303. A connecting block 310 is evenly welded to the bottom ring block 308. Below the bottom ring block 308, an outer ring block 309 is welded to the outside of the connecting block 310. An elastic ring 311 is glued to the bottom of the connecting block 310. A threaded groove 307 is opened on the inner side of the outer ring block 309. A threaded ring 312 is threaded on the inner side of the threaded groove 307. A triangular retaining ring 314 is welded to the bottom of the threaded ring 312. A knob 313 is welded to the top of the threaded ring 312. The knob 313 is located above the outer ring block 309.

[0027] When the sprayer 304 needs to be disassembled and repaired, simply rotate the knob 313 to move the threaded ring 312 inside the threaded groove 307. This causes the threaded ring 312 to move upward, which in turn moves the triangular retaining ring 314 upward. This causes the triangular retaining ring 314 to slowly disengage from the outer side of the elastic ring 311, allowing the elastic ring 311 to release its elastic potential energy and expand outward. This reduces the clamping force of the elastic ring 311 on the surface of the mounting head 303. Then, rotate the mounting head 303 to disengage it from the spray pipe, thus completing the disassembly of the sprayer 304.

[0028] The surface of the mounting head 303 is clamped by the elastic ring 311. When the sprayer 304 needs to be disassembled, simply rotate the knob 313 to disengage the elastic ring 311 from the surface of the mounting head 303, and then remove the sprayer 304. Compared with traditional desulfurization devices for industrial waste gas purification, this desulfurization device for industrial waste gas purification seals the connection between the mounting head 303 and the spray pipe 301 through the elastic ring 311, preventing water vapor from entering the connection gap and causing it to rust and age, thereby improving the service life of the sprayer 304 and the spray pipe 301.

[0029] Working principle and usage process of this utility model:

[0030] In use, the alkaline absorbent is introduced to the bottom of the spray tower 11, and then exhaust gas is introduced into the spray tower 11 through the air inlet pipe 12. At this time, the water tank 23 injects the alkaline absorbent into the interior of the first spray pipe 301 through the installation pipe 24 via the built-in water pump. The exhaust gas in the spray tower 11 is sprayed by the sprayers 304 below the first spray pipe 301 and the second spray pipe 302, causing the alkaline absorbent to react with the sulfides and fall into the alkaline absorbent at the bottom of the spray tower 11. After passing through the filter box, the exhaust gas is then removed. The water pump inside 21 draws the alkaline absorbent from the bottom of the spray tower 11 into the filter box 21 for filtration. Then, the water pump inside the water tank 23 draws the filtered alkaline absorbent from the filter box 21 into the water tank 23. The water is then circulated through the installation pipe 24. When water vapor adheres to the surface of the sprayer 304, it is caused by gravity to form small water droplets that move along the arc groove 305 towards the edge of the sprayer 304, thereby reducing the number of water droplets around the atomizing nozzle 306.

[0031] When the sprayer 304 needs to be disassembled and repaired, simply rotate the knob 313 to move the threaded ring 312 inside the threaded groove 307. This causes the threaded ring 312 to move upward, which in turn moves the triangular retaining ring 314 upward. This causes the triangular retaining ring 314 to slowly disengage from the outer side of the elastic ring 311, allowing the elastic ring 311 to release its elastic potential energy and expand outward. This reduces the clamping force of the elastic ring 311 on the surface of the mounting head 303. Then, rotate the mounting head 303 to disengage it from the spray pipe, thus completing the disassembly of the sprayer 304.
