Abstract
Description
Technical Field
[0001] This utility model relates to the field of desulfurization technology, specifically to a desulfurization reaction system. Background Technology
[0002] Hydrogen sulfide is a common harmful component in natural gas. It is a highly toxic gas; low concentrations (50-100 ppm) can cause headaches, nausea, and irritation to the eyes and respiratory tract; high concentrations (above 500 ppm) can lead to coma, respiratory paralysis, or even death within a short period of time.
[0003] Therefore, hydrogen sulfide removal is essential and a necessary step in many chemical processes. There are two main methods for hydrogen sulfide removal: dry and wet methods. Iron-based desulfurizing agents are widely used due to their advantages such as wide availability, low price, and high sulfur capacity. However, in related technologies, the desulfurizing agent needs to be replaced or regenerated after deactivation, leading to intermittent operation of the entire desulfurization system and making it impossible to guarantee continuous desulfurization, thus affecting production continuity. Utility Model Content
[0004] In view of this, the present invention provides a desulfurization reaction system to solve the problem that the desulfurization reaction system cannot guarantee continuous desulfurization, thus affecting the continuity of production.
[0005] This utility model provides a desulfurization reaction system, including a desulfurization reactor, a waste agent processor, and a desulfurizing agent storage tank. At least two desulfurization reactors are provided and connected in parallel. Each desulfurization reactor has a reaction chamber suitable for introducing the gas to be desulfurized. The inlet of the waste agent processor is connected to the desulfurization reactor via an automatic unloading pipeline. The outlet of the desulfurizing agent storage tank is connected to the desulfurization reactor via a first automatic filling pipeline, and the inlet of the desulfurizing agent storage tank is connected to the waste agent processor via an automatic transfer pipeline.
[0006] Beneficial effects: By connecting multiple desulfurization reactors in parallel, when the desulfurizing agent in one desulfurization reactor is close to saturation or deactivated, it can be switched out of the system for regeneration by switching valves. At the same time, other desulfurization reactors can continue to operate, ensuring that the entire desulfurization process of the system is uninterrupted and improving the system's desulfurization efficiency. The waste desulfurization agent is treated by the waste agent processor, and the restored desulfurization agent is transported to the desulfurization agent storage tank to facilitate the recycling of the desulfurization agent.
[0007] In one optional embodiment, the desulfurization reaction system further includes a separator disposed between the desulfurization reactor and the waste agent processor, wherein the inlet end of the separator is connected to the desulfurization reactor and the outlet end of the separator is connected to the waste agent processor.

[0009] In one optional embodiment, the desulfurization reaction system further includes an inert support storage container, the outlet of which is connected to the desulfurization reactor via a second automatic filling pipeline. The height of the inert support storage container and the height of the desulfurizing agent storage container are both higher than the height of the desulfurization reactor, and the height of the desulfurization reactor is higher than the height of the waste agent processor.
[0010] Beneficial effects: The inert support storage tank, desulfurizing agent storage tank, desulfurization reactor and waste agent processor are arranged sequentially from high to low. The height difference is used to realize the filling of inert support and desulfurizing agent, as well as the unloading of desulfurization waste agent, thus achieving the effect of energy saving and consumption reduction.
[0011] In one alternative embodiment, the desulfurization reaction system further includes a pressure sensor disposed on the desulfurization reactor, the pressure sensor being adapted to detect the pressure within the reaction chamber.
[0012] Beneficial effects: The pressure in the reaction chamber is monitored in real time by a pressure sensor. When the pressure drop in the reaction chamber is too large, the desulfurization reactor can be dealt with in a timely manner.
[0013] In one optional embodiment, the desulfurization reaction system further includes a temperature and humidity sensor disposed on the desulfurization reactor, the temperature and humidity sensor being adapted to detect the temperature and humidity inside the reaction chamber.
[0014] Beneficial effects: The temperature and humidity inside the reaction chamber are monitored in real time by temperature and humidity sensors. When the temperature or humidity inside the reaction chamber is too high, the desulfurization reactor can be dealt with in a timely manner.
[0015] In one optional embodiment, a plurality of pressure sensors and temperature and humidity sensors are provided, with the plurality of pressure sensors and the plurality of temperature and humidity sensors being arranged at intervals along the desulfurization reactor.
[0016] Beneficial effects: Multiple pressure sensors and multiple temperature and humidity sensors are set at intervals, thereby enabling multi-point measurement of pressure, temperature and humidity in the reaction chamber, thus improving the accuracy of detection.
[0017] In one optional embodiment, the desulfurization reaction system further includes a temperature and humidity measuring device and a dust collector, wherein the temperature and humidity measuring device and the dust collector are respectively connected to the waste agent processor.
[0018] Beneficial effects: By using temperature and humidity measuring devices to detect the temperature and humidity inside the waste gas processor, the heat generated during the regeneration of desulfurization waste agent can be prevented from causing excessively high temperatures and safety hazards; by installing a dust collector, the dusty waste agent can be collected and treated, ensuring the safety of the system environment and preventing harm to operators.
[0019] In one optional embodiment, a processing chamber is formed within the waste agent processor, and the waste agent processor has an air inlet and a pressure relief port, which are respectively connected to the processing chamber.
[0020] Beneficial effects: Air is introduced into the treatment chamber through the air inlet, and the oxygen in the air is used to restore the desulfurization waste agent to a certain degree of activity and recycle it; the pressure is released to the outside in a timely manner through the pressure relief port to prevent excessive pressure in the treatment chamber and avoid safety hazards.
[0021] In one optional embodiment, the desulfurization reactor includes a shell and a partition, the reaction chamber is formed inside the shell, the partition is disposed inside the reaction chamber and connected to the shell, and the partition has a plurality of perforations that are suitable for the gas to be desulfurized to pass through.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] The following is combined with Figure 1 The following describes embodiments of the present invention.
[0031] According to an embodiment of the present invention, a desulfurization reaction system is provided, including a desulfurization reactor 10, a waste agent processor 20, and a desulfurizing agent storage tank 30. Two desulfurization reactors 10 are provided and connected in parallel. A reaction chamber is formed inside the desulfurization reactor 10, and the reaction chamber is suitable for introducing the gas to be desulfurized. The inlet end of the waste agent processor 20 is connected to the desulfurization reactor 10 through an automatic unloading pipeline 101. The outlet end of the desulfurizing agent storage tank 30 is connected to the desulfurization reactor 10 through a first automatic filling pipeline 102, and the inlet end of the desulfurizing agent storage tank 30 is connected to the waste agent processor 20 through an automatic transmission pipeline 103.
[0032] The desulfurization reaction system of this embodiment uses multiple desulfurization reactors 10 connected in parallel. When the desulfurizing agent in a certain desulfurization reactor 10 is close to saturation or deactivated, it can be switched out of the system for regeneration by switching valves. At the same time, other desulfurization reactors 10 can continue to operate, ensuring that the entire desulfurization process of the system is uninterrupted and improving the system's desulfurization efficiency. The waste desulfurization agent is processed by the waste agent processor 20 and the restored desulfurization agent is transported to the desulfurization agent storage tank 30 for recycling.
[0033] It should be noted that in the relevant technologies, the desulfurizing agent needs to be shut down for replacement or regeneration after it becomes deactivated, which causes the entire desulfurization system to operate intermittently, making it impossible to guarantee continuous desulfurization and affecting the continuity of production.
[0034] Therefore, in this embodiment, by connecting multiple desulfurization reactors 10 in parallel, each desulfurization reactor 10 works independently. Even if one of the desulfurization reactors 10 is shut down or under maintenance, the desulfurization reaction system can still perform desulfurization of the gas to be desulfurized, ensuring that the entire desulfurization process of the system is uninterrupted and improving the system's desulfurization efficiency.
[0035] Specifically, the desulfurization reactor 10 is a cylinder with a bottom diameter of 2m and a height of 10m.
[0036] It should be noted that in other alternative embodiments, the desulfurization reactor 10 can also be a square column, and its relevant dimensions can be adjusted according to the actual situation.
[0037] It should be noted that in other alternative embodiments, multiple desulfurization reactors 10 can be connected in parallel.
[0038] In one embodiment, such as Figure 1 As shown, the desulfurization reaction system also includes a separator 40, which is located between the desulfurization reactor 10 and the waste agent processor 20. The inlet end of the separator 40 is connected to the desulfurization reactor 10, and the outlet end of the separator 40 is connected to the waste agent processor 20.
[0039] Specifically, such as Figure 1 As shown, the inlet end of separator 40 is connected to both desulfurization reactors 10.
[0040] It should be noted that the desulfurization reactor 10, the automatic unloading pipeline 101, the separator 40, and the waste agent processor 20 are all made of corrosion-resistant materials.
[0041] It is worth noting that by setting up the separator 40, the used granular waste agent, powdered waste agent and inert support are separated to achieve the separation of inert support and desulfurization waste agent, so as to facilitate the separate treatment of inert support and desulfurization waste agent.
[0042] In one embodiment, such as Figure 1 As shown, the desulfurization reaction system also includes an inert support storage tank 50. The outlet end of the inert support storage tank 50 is connected to the desulfurization reactor 10 through a second automatic filling pipeline 104. The height of the inert support storage tank 50 and the height of the desulfurizing agent storage tank 30 are both higher than the height of the desulfurization reactor 10, and the height of the desulfurization reactor 10 is higher than the height of the waste agent processor 20.
[0043] It is worth noting that the inert support storage 50, the desulfurizing agent storage 30, the desulfurization reactor 10, and the waste agent processor 20 are arranged sequentially from high to low. The height difference is used to realize the filling of inert support and desulfurizing agent, as well as the unloading of desulfurization waste agent, thus achieving the effect of energy saving and consumption reduction.
[0044] Specifically, in the reaction chamber, an inert support is placed below the desulfurizing agent to provide support for it.
[0045] In one embodiment, such as Figure 1 As shown, the desulfurization reaction system also includes a pressure sensor 60, which is installed on the desulfurization reactor 10 and is adapted to detect the pressure inside the reaction chamber.
[0046] For details, please refer to Figure 1 Each desulfurization reactor 10 is equipped with two pressure sensors 60, which are arranged at intervals from top to bottom.
[0047] It is worth noting that the pressure in the reaction chamber is monitored in real time by the pressure sensor 60. When the pressure drop in the reaction chamber is too large, the desulfurization reactor 10 can be dealt with in a timely manner.
[0048] In one embodiment, such as Figure 1 As shown, the desulfurization reaction system also includes a temperature and humidity sensor 70, which is installed on the desulfurization reactor 10 and is suitable for detecting the temperature and humidity inside the reaction chamber.
[0049] For details, please refer to Figure 1 Each desulfurization reactor 10 is equipped with two temperature and humidity sensors 70, which are arranged at intervals from top to bottom.
[0050] It is worth noting that the temperature and humidity inside the reaction chamber are monitored in real time by the temperature and humidity sensor 70. When the temperature or humidity inside the reaction chamber is too high, the desulfurization reactor 10 can be dealt with in a timely manner.
[0051] Of course, in other alternative implementations, the number of pressure sensor 60 and temperature and humidity sensor 70 can be adjusted according to the actual situation, for example, three or four.
[0052] It is worth noting that multiple pressure sensors 60 and multiple temperature and humidity sensors 70 are spaced apart to achieve multi-point measurement of pressure, temperature and humidity in the reaction chamber, thereby improving the accuracy of detection.
[0053] In one embodiment, such as Figure 1 As shown, the desulfurization reaction system also includes a temperature and humidity measuring device 80 and a dust collector 90, which are respectively connected to the waste agent processor 20.
[0054] It should be noted that heat is generated during the regeneration of desulfurization waste agent. High temperature will increase the pressure inside the waste agent processor 20, and may even cause thermal runaway. If the humidity in the waste agent processor 20 is too high, water vapor and hydrogen sulfide gas released during regeneration will form an acidic aqueous solution, which will adhere to the inner wall of the waste agent processor 20 and cause corrosion of the waste agent processor 20.
[0055] It is worth noting that the temperature and humidity inside the exhaust gas processor are monitored by the temperature and humidity measuring device 80 to prevent the release of heat during the regeneration of desulfurization waste agent, which could lead to excessively high temperatures and safety hazards. The dust collector 90 is installed to collect and treat the dusty waste agent, ensuring the safety of the system environment and preventing harm to the operator.
[0056] In one embodiment, such as Figure 1 As shown, a processing chamber is formed inside the waste agent processor 20. An air inlet 21 and a pressure relief port 22 are provided on the waste agent processor 20, and the air inlet 21 and the pressure relief port 22 are respectively connected to the processing chamber.
[0057] It is worth noting that air is introduced into the treatment chamber through air inlet 21, and the oxygen in the air is used to restore the desulfurization waste agent to a certain degree of activity and recycle it; the pressure is released to the outside in a timely manner through pressure relief port 22 to prevent excessive pressure in the treatment chamber and avoid safety hazards.
[0058] It should be noted that in other alternative embodiments, the waste agent processor 20 can also reduce the desulfurization waste agent by other methods, such as purging the desulfurization agent with inert gas to remove the adsorbed sulfur components; using the desulfurization agent as an electrode or placing it in an electrolytic cell to promote the decomposition or dissolution of sulfur compounds by applying current, etc.
[0059] In one embodiment, such as Figure 1 As shown, the desulfurization reactor 10 includes a shell 11 and a partition 12. A reaction chamber is formed inside the shell 11. The partition 12 is disposed inside the reaction chamber and connected to the shell 11. Several perforations are provided on the partition 12, which are suitable for the gas to be desulfurized to pass through.
[0060] Specifically, the partition 12 is a mesh partition 12 and is made of a metal material that is not easily deformed.
[0061] It should be noted that the smaller the perforation size, the better, in order to reduce the leakage of desulfurizing agent and inert support.
[0062] It is worth noting that a perforated baffle 12 is installed inside the reaction chamber to ensure the passage of the gas to be desulfurized and to prevent the desulfurizing agent and inert support from leaking downwards.
[0063] Furthermore, such as Figure 1 As shown, the desulfurization reactor 10 also includes a support column 13, which is located at the bottom of the shell 11.
[0064] It should be noted that multiple support columns 13 can be provided to improve the support capacity.
[0065] It is worth noting that the shell 11 is supported by the support column 13 to prevent the shell 11 from deforming or collapsing due to gravity.
[0066] It should be noted that in this embodiment, an automatic control module is also provided. The automatic control module can receive parameter information from the pressure sensor 60, the temperature and humidity sensor 70 and the temperature and humidity measuring device 80, and realize the automation of the entire desulfurization reaction system through the automatic unloading pipeline 101, the first automatic filling pipeline 102, the automatic transfer pipeline 103 and the second automatic filling pipeline 104, thereby reducing manual operation.
[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
