Description

Technical Field

[0001] This utility model relates to the field of gaseous sulfur equipment technology, and more specifically, to a circulation component of an absorption desulfurization device. Background Technology

[0002] Natural gas, as a clean energy source, is widely used in the chemical industry and for residential applications. However, natural gas contains hydrogen sulfide, mercaptans, heavy hydrocarbons, saturated water, and other impurities. Hydrogen sulfide in natural gas reacts with water to form a weak acid, which can cause corrosion of steel equipment and pipelines. Furthermore, if natural gas containing hydrogen sulfide is used as residential fuel, the exhaust gases produced after combustion will contain sulfides, which pollute the environment. Hydrogen sulfide is also a toxic gas; inhalation of hydrogen sulfide can lead to poisoning and disability, or even death, posing a serious threat to human health. Therefore, the extraction of natural gas must first remove hydrogen sulfide to meet the requirements for industrial production and residential commercial use.

[0003] However, traditional absorption desulfurization units have some shortcomings in the design of their circulation components. For example, the waste generated during the desulfurization process needs to be collected and treated in a timely manner to avoid secondary pollution to the environment. In addition, traditional desulfurization units often suffer from low efficiency and complex operation in terms of material conveying and waste collection, which affects the desulfurization effect and the operational stability of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a circulation component for an absorption desulfurization device, addressing some shortcomings in the design of circulation components in traditional absorption desulfurization devices as described in the background section. For example, the desulfurization efficiency of the absorbent in the desulfurization tank gradually decreases after a period of use, requiring regular replacement or regeneration. Simultaneously, the waste generated during the desulfurization process also needs to be collected and treated promptly to avoid secondary pollution and other environmental problems.

[0005] To achieve the above objectives, this utility model provides a circulation component for an absorption desulfurization device, including a desulfurization tank. A material conveying component is connected to the bottom of the desulfurization tank, and a waste collection component is connected to one end of the material conveying component. An exhaust pipe is connected to the top of the desulfurization tank, and a liquid suction pipe is connected to one side of the top of the desulfurization tank. One end of the liquid suction pipe is connected to the desulfurization tank through a return pipe, and the other end of the liquid suction pipe is connected to the waste collection component through a liquid pump.

[0006] Preferably, the feeding assembly includes a housing, a rotating shaft is installed inside the housing, a spiral pusher is installed on the rotating shaft, and one end of the rotating shaft is driven to rotate by a pusher motor.

[0007] Preferably, the top of the outer shell is provided with a feed inlet, which is connected to the bottom of the desulfurization tank, and the discharge end of the conveying assembly is connected to the waste collection assembly.

[0008] Preferably, the waste collection assembly includes a collection tank, one end of which is connected to a waste pipe, and the top of the waste pipe has an opening that is connected to the bottom end of a suction pipe.

[0009] Preferably, a filter is installed on the inside of the opening.

[0010] Preferably, the end of the collection tank away from the waste pipe is provided with a slag discharge port.

[0011] Preferably, an air inlet pipe is installed on the upper side of the desulfurization tank, and the bottom end of the return pipe is connected to the air inlet pipe.

[0012] Preferably, the rotating shaft is rotatably connected to the inner wall of the housing via a bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this absorption desulfurization unit, the optimized design of the desulfurization tank, conveying assembly, and waste collection assembly significantly improves desulfurization efficiency and operational stability. Specifically, this circulation assembly enables the recycling of the absorbent, effectively extending its service life and reducing desulfurization costs.

[0015] Meanwhile, the design of the waste collection components ensures that the waste generated during the desulfurization process can be collected and treated in a timely and effective manner, avoiding secondary pollution to the environment. Furthermore, the conveying components employ a spiral pusher structure, which improves conveying efficiency, simplifies the operation process, and further enhances the overall performance of the desulfurization unit.

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] This utility model provides a circulation component for an absorption desulfurization device, such as... Figures 1-3 As shown, the system includes a desulfurization tank 1, a conveying assembly 2 connected to the bottom of the desulfurization tank 1, a waste collection assembly 3 connected to one end of the conveying assembly 2, an exhaust pipe 5 connected to the top of the desulfurization tank 1, and a suction pipe 4 connected to one side of the top of the desulfurization tank 1. One end of the suction pipe 4 is connected to the desulfurization tank 1 via a return pipe 42, and the other end of the suction pipe 4 is connected to the waste collection assembly 3 via a pump 41. As the core component, the desulfurization tank 1, with its bottom connected to the conveying assembly 2, can continuously and stably deliver absorbent into the desulfurization tank, ensuring the continuous and efficient desulfurization reaction, thereby significantly improving desulfurization efficiency. The waste collection assembly 3, connected to one end of the conveying assembly 2, can promptly collect the waste generated during the desulfurization process, avoiding the accumulation of waste and secondary pollution within the device. Simultaneously, through the connection between the suction pipe 4 and the waste collection assembly 3, and with the assistance of the pump 41, rapid recovery and treatment of waste liquid are achieved, further improving the environmental performance of the device. One end of the suction pipe 4 is connected to the desulfurization tank 1 via the return pipe 42. This design allows the absorbent to be treated and returned to the desulfurization tank after use, achieving resource recycling and reducing desulfurization costs. The design of the entire circulation assembly takes into account ease of operation and operational stability. Through reasonable layout and connection, the device can maintain a stable working state during operation, reducing the possibility of failure and also reducing operating difficulty and maintenance costs.

[0023] In this embodiment, the conveying assembly 2 includes a housing 21, inside which a rotating shaft 22 is installed. A spiral pusher blade 23 is mounted on the rotating shaft 22, and one end of the rotating shaft 22 is driven to rotate by a pusher motor 24. In this embodiment, the conveying assembly 2, through the rotating shaft 22 and spiral pusher blade 23 installed inside the housing 21, combined with the drive of the pusher motor 24, achieves efficient and continuous conveying of the absorbent. This design not only ensures a sufficient supply of absorbent in the desulfurization tank 1, but also improves the uniformity and stability of the conveying through the pushing action of the spiral pusher blade 23, thereby optimizing the desulfurization process.

[0024] Specifically, the top of the outer casing 21 is provided with a feed inlet 211, which is connected to the bottom of the desulfurization tank 1. The discharge end of the conveying assembly 2 is connected to the waste collection assembly 3. This design allows the absorbent to enter the conveying assembly directly from the bottom of the desulfurization tank, reducing material transfer and waste. At the same time, the discharge end of the conveying assembly 2 is connected to the waste collection assembly 3, realizing timely discharge and collection of waste, and improving the continuity and automation of the entire desulfurization unit.

[0025] Furthermore, the waste collection assembly 3 includes a collection tank 31, one end of which is connected to a waste pipe 32. The top of the waste pipe 32 has an opening 33, which connects to the bottom end of a suction pipe 4. By connecting the opening 33 at the top of the waste pipe 32 to the bottom end of the suction pipe 4, rapid recovery of waste liquid is achieved. This design not only simplifies the waste collection process but also improves the recovery efficiency of waste liquid and reduces leakage and pollution through the suction action of the suction pipe 4.

[0026] Furthermore, a filter 34 is installed inside the opening 33. This design effectively filters out solid particles and impurities in the waste, preventing them from entering the suction pipe 4 and the desulfurization tank 1, thereby protecting the normal operation of the desulfurization unit and extending its service life. The filter 34 is an anti-clogging filter in the prior art, and its specific structure will not be described in detail here.

[0027] Furthermore, a slag discharge port 35 is provided at the end of the collection tank 31 away from the waste pipe 32. This design allows solid waste in the collection tank 31 to be easily discharged, facilitating subsequent cleaning and treatment. At the same time, the slag discharge port also improves the flexibility and practicality of the waste collection assembly 3.

[0028] Furthermore, an air inlet pipe 11 is installed on the upper side of the desulfurization tank 1, and the bottom end of the return pipe 42 is connected to the air inlet pipe 11. This design allows the treated absorbent to flow back into the desulfurization tank 1, realizing resource recycling. At the same time, the air inlet pipe 11 also provides fresh air or oxygen to the desulfurization tank 1, which helps the desulfurization reaction to proceed.

[0029] Furthermore, the rotating shaft 22 is rotatably connected to the inner wall of the housing 21 via a bearing. This design not only ensures the stable rotation of the rotating shaft 22, but also reduces friction and wear during rotation, thereby improving the operational stability and service life of the material conveying assembly 2.

[0030] In the circulation component of the absorption desulfurization device of this utility model, the exhaust gas first enters the bottom of the desulfurization tank 1 through the air inlet pipe 11 at the top of the desulfurization tank 1. Inside the desulfurization tank 1, the exhaust gas reacts chemically with the absorbent in the desulfurization tank, absorbing the hydrogen sulfide in the exhaust gas and generating the corresponding desulfurization products.

[0031] When the absorbent in desulfurization tank 1 decreases or needs to be replaced, the conveying assembly 2 starts working. The pusher motor 24 drives the rotating shaft 22 to rotate, and the spiral pusher blades 23 on the rotating shaft 22 rotate accordingly, pushing the absorbent located in the outer shell 21 from the feed port 211 (connected to the bottom of desulfurization tank 1) to the discharge end. The continuous and stable conveying of absorbent by the conveying assembly 2 ensures that there is always enough absorbent in desulfurization tank 1 for the desulfurization reaction.

[0032] Waste generated during the desulfurization process (including waste liquid and solid particles) enters the waste collection assembly 3 through a specific channel. Waste liquid is drawn in by the suction pump 41 through the suction pipe 4 and enters the collection tank 31 through the opening 33 at the top of the waste pipe 32. A filter 34 installed inside the opening 33 filters out solid particles and impurities from the waste liquid, preventing them from entering the desulfurization tank 1 and causing pollution. The filtered waste liquid accumulates in the collection tank 31, and once a certain amount is reached, it can be further treated or discharged through other equipment. Solid waste is discharged through the slag discharge port 35 at the end of the collection tank 31 furthest from the waste pipe 32, facilitating subsequent cleaning and treatment.

[0033] After the desulfurization reaction, a portion of the absorbent (such as slurry containing desulfurization products) enters the return pipe 42 through specific pipelines and pumping devices. The bottom end of the return pipe 42 is connected to the air inlet pipe 11 at the top of the desulfurization tank 1, allowing the treated absorbent to flow back into the desulfurization tank. During the return process, the useful components in the absorbent are recycled, reducing desulfurization costs.

[0034] Through a rational layout and connection design, the entire circulation assembly maintains a stable working state during operation, reducing the possibility of malfunctions. The design of components such as the material conveying assembly 2 and the waste collection assembly 3 takes into account ease of operation, enabling operators to easily perform daily maintenance and troubleshooting. The placement of components such as the desulfurization tank 1, the inlet pipe 11, and the return pipe 42 also fully considers the equipment's operating efficiency and environmental performance, ensuring the efficient and stable operation of the desulfurization process.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
