Description

Technical Field

[0001] This utility model belongs to the field of wet deacidification technology, and in particular relates to an activated carbon wet deacidification device. Background Technology

[0002] In the production processes of industries such as petroleum, chemical, and power, a certain amount of waste gas is generated, including acidic gases containing sulfur dioxide and sulfur trioxide. According to environmental protection requirements, this waste gas must undergo deacidification treatment to meet standards. Therefore, deacidification equipment is installed in these process systems. Especially in the waste sulfuric acid resource recovery process of petrochemical plants, the deacidification unit not only ensures that the acidic gases meet environmental standards but also significantly impacts the overall efficiency of concentrated sulfuric acid production, as the collected dilute sulfuric acid can be returned as raw material to the upstream unit to produce concentrated sulfuric acid.

[0003] Specific deacidification methods include dry, semi-dry, and wet methods. Wet deacidification, depending on the deacidifying agent, can be further divided into lime-gypsum deacidification and magnesium oxide deacidification. Their reaction mechanism involves oxidizing sulfur dioxide to sulfur trioxide under oxygen-rich conditions in the deacidification unit. Sulfur trioxide dissolves in water to form sulfate ions. These sulfate ions then combine with cations in the deacidifying agent to form water-insoluble sulfates, such as calcium sulfate dihydrate (gypsum) and magnesium sulfate. These products are ultimately separated and removed in solid form, thus achieving the deacidification effect. Wet deacidification has relatively high efficiency and is therefore widely used.

[0004] Although wet deacidification technology has a high deacidification efficiency, it still has significant drawbacks in actual operation:

[0005] First, operating costs are high. The consumption of reagents (such as lime and magnesium oxide) and associated energy consumption continuously drive up operating costs. Second, the system is complex and requires a large footprint. Multi-stage reaction towers, sedimentation tanks, and solid waste treatment units result in a large equipment footprint and increased maintenance difficulty. Third, the risk of scaling is significant. During the liquid-solid reaction, hard scale easily forms on the surfaces of pipes and spray devices, causing blockages and reducing system stability. Fourth, byproduct disposal is difficult. The generated sulfate solids require additional dewatering and filtration equipment, increasing investment costs; their storage or landfill may also cause secondary pollution. Utility Model Content

[0006] In view of this, the present invention aims to propose an activated carbon wet desulfurization device to solve the problems of high operating cost, easy scaling, and difficult disposal of by-products in traditional wet desulfurization devices.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a wet activated carbon deacidification device, wherein the deacidification device is a box-type structure, including a shell, a horizontally arranged dividing wall plate inside the shell, the dividing wall plate dividing the interior of the shell into upper and lower regions, the lower region being a primary deacidification zone and the upper region being a secondary deacidification zone, an air inlet port being provided on the front side of the shell, an air inlet pipe being inserted into the air inlet port, the air inlet pipe being located in the primary deacidification zone, an air outlet being provided at the lower part of the air inlet pipe, a primary activated carbon assembly being provided in the primary deacidification zone, the primary activated carbon assembly being located above the air inlet pipe, and a primary hanger being provided at the lower part of the dividing wall plate. The primary hanger is connected to a primary spray pipe below it. An air vent is provided on the partition wall panel, and a primary demister is installed on the air vent. A secondary activated carbon assembly is installed in the secondary deacidification zone. A secondary hanger is installed on the inner wall of the top of the shell, and a secondary spray pipe is connected below the secondary hanger. Multiple atomizing nozzles are installed below both the primary and secondary spray pipes. An air outlet pipe is installed above the shell, communicating with the secondary deacidification zone. A secondary demister is installed inside the air outlet pipe, which is connected to a gas collecting pipe. The shell is connected to two dilute sulfuric acid outlets, located on the bottom surface of the shell's inner cavity and the upper surface of the partition wall panel, respectively.

[0008] Furthermore, the rear side of the housing is provided with a first manhole, a second manhole, a third manhole, and a fourth manhole from bottom to top. The first and second manholes are located in the primary deacidification zone, and the third and fourth manholes are located in the secondary deacidification zone.

[0009] Furthermore, the two dilute sulfuric acid outlets are respectively located below the first-layer manhole and the third-layer manhole.

[0010] Furthermore, the outlet pipe is connected to the collection pipe via a flexible connection structure, which is located on the upper part of the secondary demister.

[0011] Furthermore, there are multiple air outlet pipes, the upper ends of which are connected to an air collection pipe, the lower part of which is connected to a support, and the support is connected to the housing.

[0012] Furthermore, the side of the housing is provided with multiple observation holes and multiple thermometer interfaces, and a thermometer is installed in each thermometer interface. A thermometer is installed in both the primary deacidification zone and the secondary deacidification zone.

[0013] Furthermore, a primary bracket is provided in the primary deacidification zone, and the primary activated carbon assembly is placed on the primary bracket; a secondary bracket is provided in the secondary deacidification zone, and the secondary activated carbon assembly is placed on the secondary bracket.

[0014] Furthermore, the inner walls of both the primary deacidification zone and the secondary deacidification zone are equipped with liners.

[0015] Furthermore, both the bottom of the partition wall panel and the shell are inclined surfaces.

[0016] Furthermore, the side of the primary spray pipe is the primary spray pipe inlet, and the side of the secondary spray pipe is the secondary spray pipe inlet. The primary spray pipe inlet and the secondary spray pipe inlet are respectively connected to a water source, and the spray water mist area formed by the multiple atomizing nozzles completely covers the activated carbon component.

[0017] This utility model also provides a deacidification method for the aforementioned activated carbon wet deacidification device, as follows:

[0018] Acid-containing gas enters the primary deacidification zone through the inlet pipe for primary deacidification. The acid-containing gas passes upward through the primary activated carbon component. Inside the primary activated carbon component, sulfur dioxide in the acid gas undergoes an oxidation reaction to generate sulfur trioxide. The primary spray pipe sprays water onto the primary activated carbon component through multiple atomizing nozzles. When sulfur trioxide comes into contact with water, the water generates dilute sulfuric acid.

[0019] After primary deacidification, the acidic gas enters the secondary deacidification zone after being demisted by the primary demister. Secondary deacidification is carried out in the secondary deacidification zone. The secondary deacidification process is the same as that of the primary deacidification. The generated dilute sulfuric acid is discharged and collected through the dilute sulfuric acid outlet.

[0020] After secondary acid removal, the gas enters the outlet pipe, is demisted by the secondary demister, and is then discharged through the gas collection pipe.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention provides an activated carbon wet desulfurization device that significantly reduces operating costs. Traditional wet desulfurization technologies rely on reagents such as lime or magnesium oxide as desulfurizing agents, resulting in high reagent consumption and energy consumption. This device, however, uses water as the desulfurizing agent, combining the adsorption and catalytic functions of activated carbon to oxidize sulfur dioxide to sulfur trioxide in an oxygen-rich environment, and then generates dilute sulfuric acid through water spraying. This process completely avoids the use of traditional reagents, significantly reducing reagent procurement and energy consumption costs. Furthermore, since dilute sulfuric acid can be directly collected as a byproduct, no additional solid waste treatment is required, further saving on disposal costs. This is particularly suitable for the resource recovery process of waste sulfuric acid in petrochemical plants, where dilute sulfuric acid can be reused as a raw material, improving the overall efficiency of concentrated sulfuric acid production and creating an economic advantage through resource recycling.

[0023] This invention features a compact and simplified structure, effectively solving the problems of system complexity and large footprint. Traditional deacidification systems often require multi-stage reaction towers, sedimentation tanks, and solid waste treatment units, resulting in bulky equipment and difficult maintenance. This invention adopts a box-type structure, dividing the interior of the shell into upper and lower primary and secondary deacidification zones via partition walls, integrating core components such as activated carbon modules, spray pipes, and demisters. This multi-layered layout makes full use of vertical space, reducing the footprint and facilitating installation in industrial sites with limited space. Furthermore, the integrally cast shell, along with detailed designs such as manholes, observation holes, and thermometer interfaces, reduces maintenance difficulty, improves operational convenience and long-term system stability, and avoids operational bottlenecks caused by structural redundancy in traditional equipment.

[0024] This invention completely eliminates the risks associated with equipment scaling and byproduct disposal. In traditional wet deacidification processes, the liquid-solid reaction easily forms hard scale on the surfaces of pipes and spray devices, causing blockages and system failures. This invention utilizes an activated carbon wet process, where sprayed water mist covers the activated carbon components to form a uniform reaction zone. As the water flows downwards, it also washes and desorbs the activated carbon, preventing scale formation. Simultaneously, the generated dilute sulfuric acid is collected through the inclined bottom of the shell and the partition wall, and directly discharged and collected via the dilute sulfuric acid outlet, eliminating the generation of sulfate solid waste. This not only prevents secondary pollution risks but also simplifies subsequent treatment processes, improves the continuity and reliability of equipment operation, and, especially with the cooperation of the primary and secondary demisters, ensures pure gas emissions and stable and efficient overall deacidification.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0037] See Figure 1-8This embodiment describes a wet activated carbon deacidification device. The device has a box-type structure, including a shell 1. A horizontally arranged dividing wall 29 divides the interior of the shell 1 into upper and lower regions. The lower region is a primary deacidification zone 27, and the upper region is a secondary deacidification zone 30. An air inlet port is located on the front side of the shell 1, into which an air inlet pipe 2 is inserted. The air inlet pipe 2 is located within the primary deacidification zone 27, and an air outlet 31 is located at its lower part. A primary activated carbon assembly 15 is arranged within the primary deacidification zone 27, positioned above the air inlet pipe 2. A primary hanger 18 is located at the lower part of the dividing wall 29, and a primary activated carbon assembly 15 is connected to the lower part of the primary hanger 18. The system includes a spray pipe 17, an air vent on the partition wall panel 29, a primary demister 19 on the air vent, a secondary activated carbon assembly 21 in the secondary deacidification zone 30, a secondary hanger 24 on the inner top wall of the housing 1, a secondary spray pipe 23 connected below the secondary hanger 24, multiple atomizing nozzles 32 below both the primary spray pipe 17 and the secondary spray pipe 23, an air outlet pipe 8 above the housing 1 connected to the secondary deacidification zone 30, a secondary demister 25 inside the air outlet pipe 8, and a gas collection pipe 11 connected to the housing 1. The housing 1 is connected to two dilute sulfuric acid outlets 3, located at the bottom of the inner cavity of the housing 1 and the upper surface of the partition wall panel 29, respectively.

[0038] In this embodiment, the rear side of the housing 1 is provided with a first layer of manhole doors 4, a second layer of manhole doors 5, a third layer of manhole doors 6, and a fourth layer of manhole doors 7 from bottom to top. The first layer of manhole doors 4 and the second layer of manhole doors 5 are located in the primary deacidification zone 27, and the third layer of manhole doors 6 and the fourth layer of manhole doors 7 are located in the secondary deacidification zone 30. The two dilute sulfuric acid outlets 3 are respectively located below the first layer of manhole doors 4 and the third layer of manhole doors 6.

[0039] In this embodiment, the outlet pipe 8 is connected to the collecting pipe 11 via a flexible connection structure 9, which is located on the upper part of the secondary demister 25. There are multiple outlet pipes 8, and the upper ends of each outlet pipe 8 are connected to the collecting pipe 11. The lower part of the collecting pipe 11 is connected to the support 10, which is connected to the housing 1.

[0040] In this embodiment, the side of the housing 1 is provided with a plurality of observation holes 12 and a plurality of thermometer interfaces, and a thermometer 13 is provided in the thermometer interface. A thermometer 13 is provided in both the primary deacidification zone 27 and the secondary deacidification zone 30.

[0041] In this embodiment, a primary bracket 14 is installed in the primary deacidification zone 27, and the primary activated carbon assembly 15 is installed on the primary bracket 14. A secondary bracket 20 is installed in the secondary deacidification zone 30, and the secondary activated carbon assembly 21 is installed on the secondary bracket 20. Liners 26 are provided on the inner walls of the shell 1 of both the primary deacidification zone 27 and the secondary deacidification zone 30. The dividing wall plate 29 and the bottom of the shell 1 are both inclined surfaces. The side of the primary spray pipe 17 is the primary spray pipe inlet 16, and the side of the secondary spray pipe 23 is the secondary spray pipe inlet 22. The primary spray pipe inlet 16 and the secondary spray pipe inlet 22 are respectively connected to a water source. The multiple atomizing nozzles 32 form a stratified water surface under a certain pressure, and the spray water mist area 28 formed by the multiple atomizing nozzles 32 completely covers the activated carbon assembly. This makes the deacidification reaction more uniform, and at the same time, the downward flow of water washes the activated carbon, achieving the desorption effect.

[0042] This embodiment of an activated carbon wet deacidification device is a box-type structure, with the main load-bearing structure supported by a shell 1, which is integrally cast. An internal partition wall 29 divides the interior of the shell 1 into upper and lower sections: a lower section for primary deacidification 27 and an upper section for secondary deacidification 30. This design helps reduce the floor space required and increases site utilization. The partition wall 29 and the bottom of the shell 1 are sloped, which facilitates the accumulation of dilute sulfuric acid. The structure above the partition wall 29 and the bottom of the shell 1 has a sloping shape with higher sides and a lower center, allowing the generated dilute sulfuric acid to accumulate at the bottom, thus facilitating better discharge.

[0043] During the casting of the shell 1, the required opening size and location are reserved. First, on the outer side of the shell 1, multiple observation holes 12 and multiple thermometer interfaces are reserved on the side of the shell 1; an air inlet interface is reserved on the front side of the shell 1; a manhole interface is reserved on the rear side of the shell 1; and an air outlet interface is reserved on the upper part of the shell 1. Inside the shell 1, air passage holes are reserved on the partition wall plate 29. The air passage holes are used as interfaces for the first-stage demister. An acid-resistant lining plate 26 is installed throughout the internal chamber of the device. The lining plate 26 is in contact with the acid-containing gas, ensuring that the acid-containing gas does not come into contact with the shell 1, thus protecting the shell 1 from corrosion.

[0044] The inlet pipe 2, observation hole 12, and manhole doors on each floor are inserted through pre-drilled holes and sealed and welded to the liner plate 26. Four outlets 31 are located at the bottom of the inlet pipe 2, positioned on both sides of the lower part of the pipe at a certain angle for more uniform airflow distribution. Acidic gas enters the primary deacidification zone 27 through the outlets 31. The outlet pipe 8 extends from the upper part of the shell 1 and is sealed and welded to the plate 26. A secondary demister 25 is installed inside the outlet pipe 8, and a flexible connection structure 9 is installed at the top. A gas collecting pipe 11 is installed above the flexible connection structure 9, through which the acidic gas is discharged. A support 10 is installed at the bottom of the gas collecting pipe 11 to bear the load.

[0045] Inside the primary deacidification zone 27, a primary bracket 14 is installed, supported on the shell 1. A primary activated carbon assembly 15 is installed on top of the primary bracket 14. A primary hanger 18 is installed below the partition wall panel 29. A primary spray pipe 17 is connected to and fixed to the primary hanger 18. The inlet 16 of the primary spray pipe is connected to a water source. A primary demister 19 is installed on the partition wall panel 29, passing through a pre-drilled hole and sealed and welded to the upper and lower lining plates 26. Inside the secondary deacidification zone 30, a secondary bracket 20 is installed, supported on the shell 1. A secondary activated carbon assembly 21 is installed on top of the secondary bracket 20. A secondary hanger 24 is installed below the top inner wall of the shell 1. A secondary spray pipe 23 is connected to and fixed to the secondary hanger 24. The inlet 22 of the secondary spray pipe is connected to a water source. A dilute sulfuric acid outlet 3 is installed below the first-layer manhole door 4 and the third-layer manhole door 6.

[0046] In this embodiment, activated carbon is combined to form components, and activated carbon is used as the reaction bed to improve reaction activity. The demister is equipped with a wind cap to block the influence of the airflow in the secondary deacidification zone 30 on the demister's demisting effect, thus ensuring the demisting effect of the primary demister 19.

[0047] This embodiment describes a deacidification method for the activated carbon wet deacidification device, as detailed below:

[0048] Acidic gas enters the primary deacidification zone 27 through the inlet pipe 2 for primary deacidification. The acidic gas rises through the primary activated carbon assembly 15. Inside the primary activated carbon assembly 15, sulfur dioxide in the acidic gas undergoes an oxidation reaction to generate sulfur trioxide. Sulfur trioxide reacts with water to form dilute sulfuric acid, releasing heat in the process. The primary spray pipe 17 provides the water required for the reaction. Water is sprayed onto the primary activated carbon assembly 15 through multiple atomizing nozzles 32, entering the chamber in a layered water surface state. The spray water mist area 28 completely covers the primary activated carbon assembly 15, ensuring uniform reaction in the activated carbon reaction zone. Simultaneously, excess water can rinse the activated carbon, achieving a desorption effect.

[0049] After primary deacidification, most of the sulfur dioxide in the acidic gas is removed, and the resulting dilute sulfuric acid flows back to the bottom of shell 1 and is discharged from dilute sulfuric acid outlet 3. The acidic gas after primary deacidification enters primary demister 19, which uses inertial force to capture acid mist and remove water mist from the acidic gas, making the gas discharged from the device purer. Under the action of gravity, it returns to primary deacidification zone 27, and the remaining acidic gas enters secondary deacidification zone 30. The working principle of secondary deacidification zone 30 is the same as that of primary deacidification zone 27. After secondary deacidification, sulfur dioxide in the acidic gas is further removed, and then it enters outlet pipe 8. After mechanical demisting by secondary demister 25, it is discharged through gas collection pipe 11 in compliance with standards. Thermometers 13 are installed in primary deacidification zone 27 and secondary deacidification zone 30 to monitor the temperature of activated carbon components. By adjusting process parameters, the activated carbon is ensured to operate within the optimal temperature range, making the deacidification device operate efficiently.

[0050] The specific embodiments of this utility model disclosed above are merely illustrative of the present utility model. These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
