Description

Technical Field

[0001] This application relates to the field of purification equipment, and more particularly to a purification device. Background Technology

[0002] Existing dry gas purification devices mainly consist of fluidized beds and fixed beds, serving as adsorption and / or absorption mechanisms. Fluidized beds allow for the online addition of new powdered active materials, enabling continuous operation; however, they require complex dust collection systems, occupy a large area, and experience significant pressure loss. While fixed beds are simpler and require less space, they cannot continuously replenish active materials. Once the active materials become saturated or the exhaust gas exceeds standards, the process must be stopped for regeneration or replenishment of new agents, which is detrimental to continuous production.

[0029] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a purification device 100 for purifying gas. The purification device 100 includes a housing 1, a baffle 2, a storage chamber 3, an air inlet 4, an air outlet 5, and a control valve 6.

[0031] The interior of the housing 1 is a cavity, and the shape of the housing 1 is set according to requirements. For example, the housing 1 is cylindrical. The bottom end of the housing 1 is provided with a discharge port 11, and the top end of the housing 1 is provided with an opening.

[0032] A baffle 2 is disposed in the cavity of the housing 1, and the baffle 2 can be multi-layered. The baffle 2 divides the cavity of the housing 1 into a first air chamber 12, a purifying agent channel 13, and a second air chamber 14 arranged from the outside to the inside. For example, in a cylindrical housing 1, the baffle 2 is also cylindrical, with the outermost layer being the first air chamber 12, the inner side of the first air chamber 12 being the purifying agent channel 13, and the inner side of the purifying agent channel 13 being the second air chamber 14. The bottom end of the purifying agent channel 13 is directly connected to the discharge port 11.

[0033] like Figure 3As shown, the baffle 2 is provided with multiple vent holes 21, the shape and number of which are set according to requirements. The gas in the first air chamber 12 can enter the second air chamber 14 through the multi-layer baffle 2, and the second air chamber 14 can enter the first air chamber 12 through the multi-layer baffle 2.

[0034] Storage chamber 3 is located at the top of shell 1, and it closes the top opening of shell 1. A feed inlet 31 is located at the top of storage chamber 3, and the bottom of storage chamber 3 is connected to the top of purifying agent channel 13. Purifying agent enters storage chamber 3 through feed inlet 31 and is stored therein; optionally, the purifying agent is activated carbon. The purifying agent in storage chamber 3 flows into purifying agent channel 13 and fills it. When outlet 11 is opened, the purifying agent in purifying agent channel 13 is discharged from shell 1, and the purifying agent in storage chamber 3 replenishes purifying agent channel 13, creating a downward flow of purifying agent within purifying agent channel 13.

[0035] Both the air inlet 4 and the air outlet 5 are located on the housing 1. The air inlet 4 is used to deliver gas into the cavity. When the gas in the cavity flows through the purifying agent channel 13, it comes into contact with the purifying agent to complete the purification of the gas. The purified gas is discharged through the air outlet 5.

[0036] Control valve 6 is used to control the opening and closing of discharge port 11. When control valve 6 is open, the purifying agent at the bottom of the purifying agent channel 13 is discharged through discharge port 11, and the purifying agent in storage chamber 3 flows into the purifying agent channel 13 from the top, realizing the replacement of the purifying agent. The opening and closing of control valve 6 can be set according to requirements. Optionally, control valve 6 can also control the discharge speed of the purifying agent.

[0037] The purification device 100 of this embodiment stores the purifying agent in the storage chamber 3. The purifying agent in the purifying agent channel 13 is discharged through the control valve 6, and the purifying agent in the storage chamber 3 enters the purifying agent channel 13 to replenish the purifying agent in the purifying agent channel 13, so as to realize continuous operation.

[0038] In some embodiments, the purification device 100 further includes a first partition plate 15, which is disposed in the first air chamber 12 and divides the first air chamber 12 into multiple layers. For example, the housing 1 is cylindrical, the first partition plate 15 is annular, and there is one first partition plate 15, which divides the first air chamber 12 into two layers that are not directly connected vertically.

[0039] The gas delivered through inlet 4 enters the first chamber 12, for example, the lower layer of the first chamber 12. After passing through purification channel 13, it enters the second chamber 14. The gas rises in the second chamber 14, passes through purification channel 13 again, and enters the upper layer of the first chamber 12, completing the gas purification process. The purified gas is then discharged through outlet 5. Dividing the first chamber 12 into multiple layers allows for multiple purifications of the gas, improving the purification effect and increasing the utilization rate of the purifying agent.

[0040] like Figure 4 As shown, the purification device 100 also includes a second partition plate 16, which is disposed in the second air chamber 14. The second partition plate 16 divides the second air chamber 14 into multiple layers that are not directly connected vertically. In the vertical direction, the first partition plate 15 and the second partition plate 16 are staggered.

[0041] For example, Figure 4 Hollow arrows indicate the gas flow direction, while solid arrows indicate the purifying agent flow direction. There are two first partition plates 15, which divide the first gas chamber 12 into a first outer layer 121, a second outer layer 122, and a third outer layer 123 arranged from bottom to top. There is one second partition plate 16, which divides the second gas chamber 14 into a first inner layer 141 and a second inner layer 142 arranged from bottom to top. Vertically, the second partition plate 16 is located between the two first partition plates 15. Gas enters the first outer layer 121 through the air inlet 4, passes through the purification channel 13 into the first inner layer 141, then through the purification channel 13 into the second outer layer 122, then through the purification channel 13 into the second inner layer 142, and finally through the purification channel 13 into the third outer layer 123. The purified gas in the third outer layer 123 is then discharged through the air outlet 5. Dividing both the first gas chamber 12 and the second gas chamber 14 into multiple layers is beneficial to improving the gas purification effect and the utilization rate of the purifying agent.

[0042] In some embodiments, the air inlet 4 is located at the end of the housing 1 away from the storage chamber 3, and the air outlet 5 is located at the end of the housing 1 close to the storage chamber 3. When the first air chamber 12 is divided into multiple layers, the gas flows from top to bottom in the cavity of the housing 1. The purifier in the purifier channel 13 comes into contact with the gas, and the purification capacity gradually decreases from top to bottom. The gas in the cavity first comes into contact with the purifier at the lower part of the purifier channel 13 to fully utilize the purifier's purification capacity. After flowing to the upper part of the cavity, the gas comes into contact with the purifier at the upper part of the purifier channel 13, completing the purification of the gas. In the cavity, the gas flow direction is opposite to the purifier flow direction, which can not only fully utilize the purifier's purification capacity but also achieve multiple purification of the gas.

[0043] like Figure 2As shown, in some embodiments, the air intake direction of the air inlet 4 is tangent to the housing 1. After the gas enters the cavity of the housing 1 through the air inlet 4, due to the obstruction of the housing 1, the gas forms an airflow with circular motion in the cavity. Due to the centrifugal force, the dust in the gas separates from the gas, which is beneficial to the purification of the gas.

[0044] like Figure 5 As shown, in some embodiments, the air inlet 4 extends to the first air chamber 12, and the air outlet 5 extends to the second air chamber 14. Gas enters the first air chamber 12 through the air inlet 4, and the gas in the first air chamber 12 enters the second air chamber 14 through the purifier channel 13. The purifier in the purifier channel 13 purifies the gas, and the purified gas in the second air chamber 14 is discharged through the air outlet 5.

[0045] like Figure 6 As shown, in some embodiments, the air inlet 4 extends to the second air chamber 14, and the air outlet 5 extends to the first air chamber 12. Gas enters the second air chamber 14 through the air inlet 4, and the gas in the second air chamber 14 enters the first air chamber 12 through the purifier channel 13. The purifier in the purifier channel 13 purifies the gas, and the purified gas in the first air chamber 12 is discharged through the air outlet 5.

[0046] like Figure 7 As shown, the cross-sectional area of ​​the storage chamber 3, near the end of the shell 1, gradually decreases from top to bottom. For example, the end of the storage chamber 3 near the shell 1 is an inverted cone shape. This facilitates the downward movement of the purifying agent in the storage chamber 3 under the influence of gravity.

[0047] In some embodiments, the cross-sectional area of ​​the discharge port 11 gradually decreases from top to bottom. Dust detached from the gas falls to the discharge port 11 under the influence of gravity. The inclined sidewall of the discharge port 11 allows the dust at the discharge port 11 to move downward under gravity. The dust moves to the discharge port 11 and mixes with the purifying agent. After the control valve 6 is opened, the dust is discharged with the purifying agent, avoiding the need to use a dust collection device.

[0048] Optionally, a dust baffle 17 with air holes is provided at the bottom of the second air chamber 14. The dust baffle 17 can collect dust in the second air chamber 14 and prevent gas short circuit at the bottom of the second air chamber 14.

[0049] like Figure 8 As shown, optionally, the discharge port 11 includes a first conical portion 111, a straight cylindrical portion 112, and a second conical portion 113 arranged sequentially from top to bottom. A portion of the purifying agent can accumulate in the straight cylindrical portion 112 to prevent gas in the cavity from escaping from the discharge port 11.

[0050] In some embodiments, the opening ratio of the baffle 2 near the discharge port 11 is greater than the opening ratio of the baffle 2 near the storage chamber 3. For example, the number of openings at the bottom of the baffle 2 is greater than the number of openings at the top of the baffle 2, which facilitates full utilization of the purification capacity of the purifying agent and improves the utilization efficiency of the purifying agent.

[0051] like Figure 9 and Figure 10 As shown, the cross-sectional area of ​​the purifier channel 113 near the storage chamber 3 is larger than the cross-sectional area of ​​the purifier channel 13 near the outlet 11. The horizontal thickness of the purifier in the upper part of the purifier channel 13 is larger, while the horizontal thickness of the purifier in the lower part of the purifier channel 13 is smaller. This fully utilizes the purification capacity of the purifier, while the upper purifier provides better purification of the gas.

[0052] like Figure 11 , Figure 12 and Figure 13 As shown, the air inlet 11 and air outlet 12 are located on opposite sides of the housing 1, and there are multiple outlets 11. For example, the housing 1 is square, and multiple baffles 2 are arranged in the cavity of the housing 1, dividing the cavity into a first air chamber 12, a purifying agent channel 13, and a second air chamber 14. Gas enters the cavity from one side of the housing 1 and flows out of the cavity from the other side of the housing 1, completing the purification process.

[0053] Optionally, there are multiple air inlets 4 and multiple air outlets 5, which makes the gas distribution in the cavity more uniform.

[0054] The purification device of this embodiment can be used for the purification of gases containing sulfur dioxide, hydrogen chloride, volatile organic compounds, or other acidic gases, employing different adsorbents or absorbents for purification. For example, shaped granules with alkaline substances such as calcium oxide, calcium hydroxide, sodium hydroxide, or sodium carbonate as active ingredients can be used in this purification device to remove sulfur dioxide, sulfur trioxide, hydrogen chloride, and other acidic gases. Alternatively, shaped granules made of activated carbon or activated coke can be used in the purification device to desulfurize and remove volatile organic compounds to achieve the purpose of purifying the gas. Specially shaped materials, such as polypropylene pellets, can also be used for the treatment of dusty gases.

[0055] In this embodiment of the purification device, a purification agent is stored in a storage chamber, which is connected to a purification agent channel. The purification agent in the purification agent channel is discharged through a control valve. The purification agent in the storage chamber flows into the purification agent channel to purify the gas, and the dust is discharged with the purification agent. There is no need to configure a dust collection device, and continuous operation is achieved.

[0056] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the technical solutions and core ideas of this application. Therefore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application. In summary, the content of this specification should not be construed as a limitation of this application.
