Description

Technical Field

[0001] This application relates to the field of gas purification, and in particular to a gas purification device. Background Technology

[0002] Gas purification equipment is primarily used to remove impurities and contaminants from gases or to adjust the composition of gases to meet specific purity requirements. Gas purification equipment is commonly used in the chemical and petroleum industries, pharmaceutical and biotechnology industries, electronics and semiconductor industries, residential and environmental applications, and the steel and metallurgical industries.

[0003] In the steel and metallurgical industries, gas purification equipment often encounters problems such as damage from high temperatures and corrosive gases, difficulty in controlling large gas flow rates and pressures, difficulty in controlling gas purity requirements, high operating and maintenance costs over long periods, and low waste disposal efficiency. The purity requirements are particularly stringent in the steel and metallurgical industries, especially in fine smelting and alloy preparation processes. Gas purification equipment needs to have highly efficient impurity removal capabilities to ensure that the gases supplied to the process meet the required purity standards.

[0004] In related technologies, there are already good control methods for controlling the purity requirements of gases. However, when there is a lot of moisture in the gas, the moisture will have adverse effects on gas purification equipment and industrial processes, including corrosion, condensation problems, deterioration of adsorbent performance and reactivity, thus seriously affecting the quality of steel and metallurgical products. Summary of the Invention

[0005] To address the problem that when a gas contains a large amount of moisture, moisture can adversely affect gas purification equipment and industrial processes, including corrosion, condensation, decreased adsorbent performance, and reduced reactivity, thereby severely impacting the quality of steel and metallurgical products, this application provides a gas purification device.

[0006] The gas purification device provided in this application adopts the following technical solution:

[0007] A gas purification device, comprising:

[0008] The furnace body is arranged vertically. An air inlet pipe is fixedly connected to the end of the furnace body away from the ground, and an air outlet pipe is fixedly connected to the end of the furnace body close to the ground. Gas enters through the air inlet pipe, passes through the furnace body, and flows out through the air outlet pipe.

[0009] A drying assembly is located inside the furnace body and is positioned close to the air inlet pipe. The drying assembly is used to dry the gas flowing through the furnace body.

[0010] A condensing assembly is located inside the furnace body and is positioned close to the drying assembly. The drying assembly is located between the air inlet pipe and the condensing assembly. The condensing assembly is used to condense the gas flowing through the furnace body.

[0011] A cooling component is located inside the furnace body, close to the gas outlet pipe, and between the condensing component and the gas outlet pipe. The cooling component is used to further cool the gas flowing through the furnace body.

[0012] A speed-changing assembly is located inside the furnace body, between the drying assembly and the condensing assembly, and is used to adjust the speed of gas flow inside the furnace body.

[0013] By adopting the above technical solution, when gas purity control is required in the steel and metallurgical industries, the gas is first introduced into the inlet pipe. The gas then flows sequentially through the drying component, condensing component, and cooling component. The drying component dries the flowing gas, which then enters the condensing component for condensation. The condensed gas then enters the cooling component for further cooling until the moisture in the gas is liquefied. The liquefied moisture is collected, absorbed, and stored by the cooling component. The purified gas, meeting the required purity, is then discharged through the outlet pipe. Furthermore, the variable speed component effectively regulates the gas flow rate within the furnace, further improving the efficiency of the gas purification equipment. This application addresses, to some extent, the problem in related technologies where high moisture content in the gas negatively impacts the gas purification equipment and industrial processes, including corrosion, condensation issues, adsorbent performance degradation, and reactivity effects, thus severely affecting the quality of steel and metallurgical products.

[0014] Optionally, the drying assembly includes an adsorption box and an adsorption partition. The adsorption box is fixedly connected to the furnace body. One end of the adsorption box is fixedly connected to an adsorption inlet pipe, which communicates with the inlet pipe. The other end of the adsorption box is fixedly connected to an adsorption outlet pipe, which communicates with the condensation assembly. The adsorption partition is detachably connected to the adsorption box. The adsorption box is filled with adsorbent, and the adsorption partition is used to separate different types of adsorbents.

[0015] By adopting the above technical solution, the drying component is set as a combination of an adsorption box and an adsorption partition, so that when the gas passes through the drying component, various impurities mixed in the gas will be effectively adsorbed when they pass through the adsorption box, thereby improving the purification efficiency of the gas purification equipment.

[0016] Optionally, the adsorption partition is provided in multiple parts, and different types of adsorbents are filled between two adjacent adsorption partitions.

[0017] By adopting the above technical solution, multiple adsorption partitions are set, and different types of adsorbents are filled between adjacent adsorption partitions, which further improves the purification efficiency of the gas purification equipment.

[0018] Optionally, the condensation assembly includes a condensation box and a condensation tube. The condensation box is fixedly connected to the furnace body. One end of the condensation box is fixedly connected to a condensation inlet pipe, which communicates with the adsorption outlet pipe. The other end of the condensation box is fixedly connected to a condensation outlet pipe, which communicates with the cooling assembly. The condensation tube is detachably connected to the condensation box and is filled with a refrigerant.

[0019] By adopting the above technical solution, the condensation component is set as a combination of a condensation box and a condensation tube, so that the gas after being dried and filtered by the drying component can be effectively condensed, thereby enabling the moisture in the gas to be effectively liquefied.

[0020] Optionally, the condenser tubes are arranged in a mesh pattern.

[0021] By adopting the above technical solution, the condenser tube is arranged in a grid pattern, which effectively increases the contact area between the gas and the condenser tube, thereby enabling the moisture in the gas to be effectively condensed.

[0022] Optionally, the cooling component includes a cooling box and a cooling pipe. The cooling box is fixedly connected to the furnace body. One end of the cooling box is fixedly connected to a cooling air inlet pipe, which is connected to the condensate outlet pipe. The other end of the cooling box is fixedly connected to a cooling air outlet pipe, which is connected to the outlet pipe. The cooling pipe is detachably connected to the cooling box. A heat sink is provided on the outside of the cooling pipe, and a water-absorbing layer is provided on the inner wall of the cooling pipe.

[0023] By adopting the above technical solution, the cooling component is set as a combination of cooling box and cooling pipe, so that the moisture in the gas passing through the condensation component can be further liquefied. At the same time, the liquefied moisture is effectively adsorbed by the water-absorbing layer on the inner wall of the cooling pipe, which further improves the purification effect of the gas purification equipment.

[0024] Optionally, the absorbent layer is provided with a plurality of absorbent protrusions.

[0025] By adopting the above technical solution, the setting of the water-absorbing protrusion can effectively improve the water absorption capacity of the water-absorbing layer and effectively improve the water-absorbing layer's ability to adhere to the wall of moisture in the gas, thus minimizing the possibility of moisture being trapped in the gas again.

[0026] Optionally, the cooling pipe is arranged in a spiral shape.

[0027] By adopting the above technical solution and setting the cooling pipe in a spiral shape, the flow path of the liquefied water in the gas is effectively increased, thereby effectively reducing the possibility of water being re-entered into the gas.

[0028] Optionally, the transmission assembly includes a transmission intake pipe, a transmission outlet pipe, and a transmission bladder. The transmission intake pipe is connected to the drying outlet pipe, the transmission outlet pipe is connected to the condenser intake pipe, and the transmission bladder is disposed between the transmission intake pipe and the transmission outlet pipe. The diameter of the transmission intake pipe is larger than the diameter of the transmission outlet pipe.

[0029] By adopting the above technical solution, the speed-changing component is set as a combination of a speed-changing inlet pipe, a speed-changing outlet pipe, and a speed-changing bladder. Since the diameter of the speed-changing inlet pipe is larger than that of the speed-changing outlet pipe, the gas can be fully dried by the drying component first. After being dried, it can quickly flow through the condensation component, thereby improving the purification effect of the purification equipment to a certain extent.

[0030] Optionally, multiple variable speed exhaust pipes and multiple condenser intake pipes are provided, with each variable speed exhaust pipe corresponding to one of the multiple condenser intake pipes.

[0031] By adopting the above technical solution, multiple variable speed exhaust pipes and multiple condenser intake pipes are set up, and they are arranged in a one-to-one correspondence, which effectively disperses the gas and further increases the contact area between the gas and the condenser components, thereby effectively enhancing the efficiency of liquefying the moisture in the gas.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By configuring the gas purification equipment as a combination of a furnace body, a drying component, a condensing component, a cooling component, and a speed-changing component, when the purity of gas needs to be controlled in the steel and metallurgical industries, the gas is introduced into the inlet pipe and flows through the drying component, speed-changing component, condensing component, and cooling component in sequence, thereby effectively treating the moisture mixed in the gas. This application solves to a certain extent the problem in related technologies where when there is a lot of moisture in the gas, the moisture will have adverse effects on the gas purification equipment and industrial process, including corrosion, condensation problems, deterioration of adsorbent performance, and reactivity effects, which seriously affect the quality of steel and metallurgical products.

[0034] 2. By setting the cooling component as a combination of cooling box and cooling pipe, and with the cooling pipe arranged in a spiral shape, the flow path of the liquefied water in the gas is effectively increased, thereby effectively reducing the possibility of water being re-entrained in the gas.

[0035] 3. By setting the speed-changing component as a combination of a speed-changing inlet pipe, a speed-changing outlet pipe, and a speed-changing bladder, and because the diameter of the speed-changing inlet pipe is larger than that of the speed-changing outlet pipe, the gas can be fully dried by the drying component first, and after being dried, it can quickly flow through the condensation component, thereby improving the purification effect of the purification equipment to a certain extent.

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0044] This application discloses a gas purification device.

[0045] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] It should also be noted that the gas purification equipment in this application embodiment is mainly used in the iron and steel and metallurgical industries, and the gas used is usually an inert gas such as nitrogen or argon.

[0047] Reference Figure 1 and Figure 2 The gas purification equipment includes a furnace body 1, a drying component 4, a condensing component 5, a cooling component 6, and a speed-changing component 7. When purifying gas, the gas first flows through the drying component 4, which performs drying treatment and intercepts liquid moisture in the gas. Next, it passes through the condensing component 5, which condenses the gaseous moisture, causing it to gradually transform into a liquid state. Then, the gas passes through the cooling component 6, which further transforms the gaseous moisture into a liquid state. Simultaneously, the liquid moisture is absorbed by the cooling component 6. This effectively reduces the moisture content in the gas purified by the equipment. This application addresses, to some extent, the problem in related technologies where a large amount of moisture in the gas adversely affects the gas purification equipment and industrial processes, including corrosion, condensation problems, decreased adsorbent performance, and reactivity issues, thus seriously affecting the quality of steel and metallurgical products.

[0048] Reference Figure 1In this embodiment, the furnace body 1 is vertically oriented. An air inlet pipe 2 is fixedly connected to the end of the furnace body 1 furthest from the ground, and an air outlet pipe 3 is fixedly connected to the end of the furnace body 1 closest to the ground. Gas enters through the air inlet pipe 2, passes through the furnace body 1, and flows out through the air outlet pipe 3. In this embodiment, the furnace body 1 is cubic in shape. In other embodiments, a cylindrical shape for the furnace body 1 is also a preferred embodiment.

[0049] However, it should be noted that regardless of the method of setting, the furnace body 1 should be set vertically, or at least tilted, because the gas purification equipment of this application needs to use gravity to treat the moisture in the gas.

[0050] Reference Figure 2 The drying component 4 is located inside the furnace body 1 and is positioned close to the air inlet pipe 2. The drying component 4 is used to dry the gas flowing through the furnace body 1.

[0051] Reference Figure 2 and Figure 3 The drying assembly 4 includes an adsorption box 41 and an adsorption partition 42. The adsorption box 41 is fixedly connected inside the furnace body 1. One end of the adsorption box 41 is fixedly connected to an adsorption inlet pipe 8, which communicates with the inlet pipe 2. The other end of the adsorption box 41 is fixedly connected to an adsorption outlet pipe 9, which communicates with the condensation assembly 5. The adsorption partition 42 is detachably connected inside the adsorption box 41, which is filled with adsorbent. The adsorption partition 42 is used to separate different types of adsorbents. In this embodiment, the adsorption partition 42 is arranged in the form of a grid plate. By setting the adsorption partition 42 in the form of a grid plate, the gas passing through the drying assembly 4 can contact the adsorbent inside the drying assembly 4 more evenly, thereby effectively improving the purification capacity of the gas purification equipment. In other embodiments, other forms of adsorption partition 42 can also be used. For example, using a non-woven material board as the adsorption partition 42 is also an embodiment that can be implemented in this application.

[0052] In the embodiments of this application, molecular sieves or activated carbon materials are used as adsorbents. For ease of illustration, only simple examples are provided in the accompanying drawings. In other embodiments, depending on the requirements for gas purification, other types of adsorbent materials may be used, which are also preferred embodiments of this application.

[0053] The drying component 4 is configured as a combination of an adsorption box 41 and an adsorption partition 42, so that when the gas passes through the drying component 4, various impurities mixed in the gas will be effectively adsorbed when they pass through the adsorption box 41, thereby improving the purification efficiency of the gas purification equipment.

[0054] Multiple adsorption partitions 42 are provided, and different types of adsorbents are filled between adjacent adsorption partitions 42. In this embodiment, three adsorption partitions 42 are provided, which can effectively divide the adsorption box 41 into four different spaces, and different types of adsorbents are filled between adjacent adsorption partitions 42. In other embodiments, one, two, four, or other numbers of adsorption partitions 42 can be provided, which are all preferred embodiments of this application. It should be noted that when the number of adsorption partitions 42 is set to other numbers, the size of the adsorption box 41 and the type of adsorbent filled between the adsorption partitions 42 need to be adapted according to the actual situation.

[0055] Multiple adsorption baffles 42 are provided, and different types of adsorbents are filled between adjacent adsorption baffles 42, which further improves the purification efficiency of the gas purification equipment.

[0056] The condensing component 5 is located inside the furnace body 1 and is positioned close to the drying component 4. The drying component 4 is located between the air inlet pipe 2 and the condensing component 5. The condensing component 5 is used to condense the gas flowing through the furnace body 1.

[0057] The condensing assembly 5 includes a condensing box 51 and a condensing pipe 52. The condensing box 51 is fixedly connected inside the furnace body 1. One end of the condensing box 51 is fixedly connected to a condensing inlet pipe 10, which is connected to an adsorption outlet pipe 9. The other end of the condensing box 51 is fixedly connected to a condensing outlet pipe 11, which is connected to a cooling assembly 6. The condensing pipe 52 is detachably connected inside the condensing box 51 and is filled with a refrigerant.

[0058] The condensing component 5 is configured as a combination of condensing box 51 and condensing tube 52, so that the gas after being dried and filtered by the drying component 4 can be effectively condensed, thereby effectively liquefying the moisture in the gas.

[0059] It should be noted that the method by which the refrigerant enters the condenser tube 52 in this application is a fairly conventional method for those skilled in the art, and the type of refrigerant used also needs to be determined according to the requirements of the production process.

[0060] The condenser tube 52 is arranged in a mesh pattern. In this embodiment, the mesh is a single-layer mesh. In other embodiments, setting the mesh as a double-layer or multi-layer mesh is also a preferred embodiment of this application.

[0061] The condenser tube 52 is arranged in a grid pattern, which effectively increases the contact area between the gas and the condenser tube 52, thereby enabling the moisture in the gas to be effectively condensed.

[0062] The speed-changing component 7 is located inside the furnace body 1, between the drying component 4 and the condensing component 5. The speed-changing component 7 is used to regulate the flow speed of the gas within the furnace body 1. Essentially, the speed-changing component 7 utilizes the property that the gas to be purified flows within the purification equipment, causing the gas to be partially obstructed within the condensing component 5 before entering, thus allowing for more uniform condensation. Secondly, due to the design of the speed-changing component 7, the gas flow rate is faster after entering the condensing component 5, enabling the condensed moisture to quickly enter the cooling component 6.

[0063] Reference Figure 2 and Figure 3 The transmission assembly 7 includes a transmission intake pipe 71, a transmission outlet pipe 72, and a transmission bladder 73. The transmission intake pipe 71 is connected to the drying outlet pipe 3, the transmission outlet pipe 72 is connected to the condenser intake pipe 10, and the transmission bladder 73 is disposed between the transmission intake pipe 71 and the transmission outlet pipe 72. The diameter of the transmission intake pipe 71 is larger than the diameter of the transmission outlet pipe 72.

[0064] The speed change assembly 7 is configured as a combination of a speed change inlet pipe 71, a speed change outlet pipe 72, and a speed change bladder 73. Since the diameter of the speed change inlet pipe 71 is larger than that of the speed change outlet pipe 72, the gas can be fully dried by the drying assembly 4 first. After being dried, the gas can quickly flow through the condenser assembly 5, thereby improving the purification effect of the purification equipment to a certain extent.

[0065] Multiple variable speed exhaust pipes 72 and multiple condenser intake pipes 10 are provided, with each variable speed exhaust pipe 72 corresponding to a different condenser intake pipe 10.

[0066] Multiple variable speed exhaust pipes 72 and multiple condenser intake pipes 10 are provided, and they are arranged in a one-to-one correspondence to effectively disperse the gas and further increase the contact area between the gas and the condenser component 5, thereby effectively enhancing the efficiency of liquefying the moisture in the gas.

[0067] Reference Figure 4 and Figure 5 The cooling component 6 is located inside the furnace body 1. The cooling component 6 is set close to the gas outlet pipe 3. The cooling component 6 is located between the condensing component 5 and the gas outlet pipe 3. The cooling component 6 is used to further cool the gas flowing through the furnace body 1.

[0068] The cooling component 6 includes a cooling box 61 and a cooling pipe 62. The cooling box 61 is fixedly connected inside the furnace body 1. One end of the cooling box 61 is fixedly connected to a cooling air inlet pipe 12, which is connected to a condensation air outlet pipe 11. The other end of the cooling box 61 is fixedly connected to a cooling air outlet pipe 13, which is connected to an outlet pipe 3. The cooling pipe 62 is detachably connected inside the cooling box 61. Heat sinks are provided on the outside of the cooling pipe 62, and a water-absorbing layer is provided on the inner side wall of the cooling pipe 62.

[0069] The cooling component 6 is configured as a combination of cooling box 61 and cooling pipe 62, so that the moisture in the gas passing through the condensation component 5 can be further liquefied. At the same time, the liquefied moisture is effectively adsorbed by the water-absorbing layer on the inner wall of the cooling pipe 62, which further improves the purification effect of the gas purification equipment.

[0070] Regarding the heat sink, the embodiments of this application employ an adsorption-type heat sink, which is designed based on the properties of the material itself. This type of heat sink, positioned on the outer wall of the pipe, is a conventional technique in the art and therefore will not be elaborated upon in this embodiment. In other embodiments, a more efficient heat sink with a power supply can be used, but this requires adaptive modifications to the cooling pipe 62, which is also a preferred embodiment of this application.

[0071] The absorbent layer has a plurality of absorbent protrusions 15. In this embodiment, the absorbent protrusions 15 are square. In other embodiments, the absorbent protrusions 15 can also be made into circular, triangular, or other shapes, which are all preferred embodiments of this application.

[0072] The design of the water-absorbing protrusion 15 effectively enhances the water absorption capacity of the water-absorbing layer and also effectively improves the water-absorbing layer's ability to adhere to the wall of the gas, minimizing the possibility of water being trapped in the gas again.

[0073] The cooling pipe 62 is arranged in a spiral shape.

[0074] By arranging the cooling pipe 62 in a spiral shape, the flow path of the liquefied water in the gas is effectively increased, thereby effectively reducing the possibility of water being re-entered into the gas.

[0075] It should be noted that, when conditions permit, the longer the spiral length of the cooling pipe 62 is, the better. This ensures that the moisture in the air can be fully condensed and absorbed by the water-absorbing layer on the inner wall of the cooling pipe 62.

[0076] The implementation principle of a gas purification device according to an embodiment of this application is as follows: When gas purity control is required in the steel and metallurgical industries, gas is first introduced into the inlet pipe 2. The gas enters through the inlet pipe 2 and flows sequentially through the drying component 4, the condensing component 5, and the cooling component 6. The drying component 4 dries the flowing gas. The dried gas then enters the condensing component 5, where it is condensed. The condensed gas then enters the cooling component 6, where it is further cooled until the moisture in the gas is liquefied. The liquefied water is fully collected, absorbed, and stored by the cooling component 6, while the purified gas that meets the required purity is discharged and used through the outlet pipe 3. At the same time, due to the setting of the speed-changing component 7, the flow rate of the gas in the furnace body 1 can be effectively adjusted, further improving the working efficiency of the gas purification equipment. This application solves to a certain extent the problem in the related technology that when there is a lot of water in the gas, the water will have adverse effects on the gas purification equipment and industrial process, including corrosion, condensation, deterioration of adsorbent performance, and reactivity, which seriously affects the quality of steel and metallurgical products.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
