Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, specifically to a natural gas desulfurization device. Background Technology

[0002] Natural gas desulfurization equipment is a device used to remove sulfides from natural gas. It mainly consists of absorption towers, packed towers, and scrubbing towers. The most important piece of equipment is the desulfurizer, which absorbs hydrogen sulfide and sulfur dioxide from natural gas through solid desulfurizing agents, thereby achieving the purpose of gas desulfurization.

[0003] In the natural gas desulfurization process, the desulfurizing agent reacts chemically with the sulfides in the natural gas to remove them. Taking the methyl diethanolamine (MDEA) method as an example, the MDEA solution acts as an adsorbent and comes into countercurrent contact with the acid gas under high pressure and low temperature conditions. The hydrogen sulfide and other sulfides in the acid gas are adsorbed into the liquid phase, thereby achieving desulfurization. As the reaction proceeds, the desulfurizing agent continuously reacts with the sulfides. At this time, the effective components in the desulfurizing machine will be gradually consumed. When the effective components in the desulfurizing agent decrease to a certain level, the operator needs to shut down the desulfurizing machine and stop its operation. Then, the desulfurizing machine needs to be reopened and the desulfurizing agent added to the inside of the machine. Otherwise, the desulfurization effect will be reduced. Utility Model Content

[0004] This utility model proposes a natural gas desulfurization device, which solves the problem in the existing technology that natural gas needs to react with desulfurizing agent during the desulfurization reaction, and the reaction consumes desulfurizing agent, requiring frequent shutdowns for manual replenishment, which affects the desulfurization effect.

[0031] The working principle and beneficial effects of this utility model are as follows:

[0032] In this invention, when using a desulfurizer to desulfurize natural gas, the natural gas first needs to flow into the machine through the inlet pipe for desulfurization. During desulfurization, desulfurizing agent needs to be added periodically. Before the desulfurization reaction, workers need to store the solid desulfurizing agent in the storage mechanism. Then, the machine can be started for the desulfurization reaction. After a period of desulfurization, the amount of solid desulfurizing agent in the machine will decrease. At this point, the feeding mechanism can be activated to push the solid desulfurizing agent tank in the storage mechanism into the machine, adding only one piece at a time. After adding, the feeding mechanism is pushed to cover the machine to continue the natural gas desulfurization process. Compared with existing technologies, this eliminates the need for manual opening of the machine to add desulfurizing agent, greatly improving the efficiency of natural gas desulfurization and avoiding direct contact between workers and the internal natural gas and mixture.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0040] like Figures 1-4 As shown, this embodiment proposes a natural gas desulfurization device, including a body 1, an inlet pipe 2, and an outlet pipe 3. A base 4 is fixedly connected to the bottom of the body 1. The inlet pipe 2 is connected to the outer wall of the body 1 near the top, and the outlet pipe 3 is connected to the outer wall of the body 1 away from the inlet pipe 2. It also includes a support connection mechanism, a storage mechanism, a pushing and discharging mechanism, and support rods 5. The support connection mechanism is located on the outer wall of the body 1 near the top. The storage mechanism is located on the support connection mechanism and is used to support the storage mechanism. The storage mechanism is used to store desulfurizing agent. The pushing and discharging mechanism is located on the outer wall of the storage mechanism and is used to push the desulfurizing agent stored in the storage mechanism into the body 1. Two support rods 5 are fixedly connected to the bottom of the support connection mechanism and are used to support the support connection mechanism.

[0041] In this embodiment, the support connection mechanism includes a connecting ring 101, a connecting rod 102, and a support frame 103. The connecting ring 101 is fixedly connected to the outer wall of the body 1 near the top. Two connecting rods 102 are fixedly connected to the end of the connecting ring 101 away from the body 1. The support frame 103 is fixedly connected to the top of the end of the two connecting rods 102 away from the connecting ring 101.

[0042] In this embodiment, the storage mechanism includes a fixed box 201, a discharge port 202, a discharge pipe 203, a storage box 204, and a baffle 205. The fixed box 201 is fixedly connected to the inner bottom wall of the support frame 103. The discharge port 202 is opened at the bottom of the fixed box 201 near the machine body 1. One end of the discharge pipe 203 is connected to the discharge port 202, and the other end of the discharge pipe 203 is connected to the top of the machine body 1. The storage box 204 is connected to the top of the fixed box 201. The baffle 205 is fixedly connected to the bottom of the fixed box 201. The outer side wall of one side of the baffle 205 is fixedly connected to the outer side wall of one side of the support frame 103. The purpose is to ensure that the fixed box 201 can be stably fixed on the support frame 103 and will not tip over or fall.

[0043] In this embodiment, the feeding mechanism includes an electric cylinder 301, a push rod 302, a push plate 303, a sliding plate 304, a sliding opening 305, a sliding rod 306, and a fixed plate 307. The electric cylinder 301 is mounted on the outer wall of one side of the fixed box 201. The push rod 302 is fixedly connected to the output end of the electric cylinder 301. The push plate 303 is fixedly connected to the end of the push rod 302 away from the electric cylinder 301. The sliding plate 304 is slidably connected to the inner wall of the fixed box 201. A sliding opening 305 is provided on the outer wall of one end of the fixed box 201. The slide rod 306 is fixedly connected to the outer side wall of the sliding plate 304, and the slide rod 306 extends through the sliding port 305 to the outside. The end of the slide rod 306 extending to the outside is fixedly connected to the fixing plate 307, and the outer wall of the fixing plate 307 is fixedly connected to the end of the push plate 303 away from the push rod 302. A discharge port 6 is opened at one end of the top of the sliding plate 304, so that the solid desulfurizing agent in the storage box 204 can flow through the discharge port 6 to the discharge pipe 203, and then flow through the discharge pipe 203 to the inside of the machine body 1.

[0044] In this embodiment, when using a desulfurizer to desulfurize natural gas, the worker first needs to add solid desulfurizing agent to the storage tank 204 for storage before the desulfurization reaction. At this time, the machine body 1 can be started, and natural gas flows into the machine body 1 through the inlet pipe 2. Simultaneously, the electric cylinder 301 can be started, pushing the push rod 302, which in turn moves the push plate 303, causing the sliding rod 306 to slide, connecting the discharge port 6 on the sliding plate 304 to the storage tank 204. At this point, the solid desulfurizing agent in the storage tank 204 falls into the sliding plate 304. Then, the push rod 302 pushes the sliding rod 306, moving the sliding plate 304 to the discharge port 202. The solid desulfurizing agent in the sliding plate 304 then flows into the machine body 1 through the discharge pipe 203. Once the solid desulfurizing agent has flowed into the machine body 1, the sliding plate 304 remains stationary, maintaining the connection between the machine body 1, the sliding plate 304, and the fixed tank 201. An internal sealed space is formed, where the natural gas inside the machine body 1 reacts with the solid desulfurizing agent to undergo a desulfurization reaction. The desulfurized natural gas is discharged to the next stage through the outlet pipe 3. After a period of desulfurization reaction, the electric cylinder 301 can be restarted to push the push rod 302, causing the sliding plate 304 to slide. When the sliding plate 304 slides to the storage box 204, the solid desulfurizing agent stored in the storage box 204 will fall into the discharge port 6 of the sliding plate 304. At this time, the electric cylinder 301 is used again to push the push rod 302 to push the sliding plate 304 to the discharge pipe 203, through which it flows into the machine body 1 to continue the natural gas desulfurization reaction. After a period of desulfurization reaction, the process of adding solid desulfurizing agent can be repeated to continue adding solid desulfurizing agent into the machine body 1 to prevent the solid desulfurizing agent inside the machine body 1 from decreasing and causing incomplete natural gas reaction.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
