Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas purification technology, specifically a device for purifying soluble harmful impurities in gas. Background Technology
[0002] Absorbing soluble harmful impurities in gases using water or organic solvents is a current technology for purifying soluble harmful impurities.
[0003] Most of these gas purification devices, as described in the text of Chinese Patent Publication No. CN217613892U entitled "A Soluble Gas Absorption Device," include a purification chamber for loading water or organic solvents. The harmful gas to be purified is introduced into the purification chamber through an air inlet pipe. The soluble harmful impurities in the harmful gas dissolve in the water or organic solvent and are then discharged, thereby completing the purification of the harmful gas.
[0004] In practice, as soluble harmful impurities gradually dissolve in water, the solubility of the purification solution (composed of water or organic solvents) decreases, leading to a reduction in the dissolution efficiency of soluble harmful impurities in the purification solution. Consequently, some soluble harmful impurities are discharged before they are fully dissolved. Current technologies often address this by reducing the efficiency of harmful gas delivery or shutting down the system to replace the purification solution. However, both methods reduce the efficiency of harmful gas treatment, and the latter, requiring replacement, results in the purification solution not being fully saturated and is wasted. Therefore, a solution is urgently needed. Utility Model Content
[0005] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a gas soluble harmful impurity purification device, which can continuously and efficiently realize the purification of soluble harmful impurities in the gas, and the purification liquid is fully utilized, preventing the purification liquid from being wasted due to incomplete dissolution to saturation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A device for purifying soluble harmful impurities in a gas includes a purification chamber with a cylindrical inner cavity. The inner cavity of the purification chamber is divided by partitions to form at least four isolation chambers evenly distributed around the axis of the purification chamber. The partitions are rotatable and adjustable around the axis of the purification chamber. Along the rotation direction of the partitions, the inner cavity of the purification chamber is divided into a drainage zone, a replenishment zone, and at least two purification zones, each corresponding to one of the at least four isolation chambers. The top of the isolation chamber located in the first purification zone is connected to an exhaust pipe, and the bottom of the isolation chamber located in the last purification zone is connected to an air inlet pipe. The isolation chambers in adjacent purification zones are connected to each other through connecting pipes. The bottom of the isolation chamber located in the drainage zone is connected to a drainage pipe, and the top of the isolation chamber located in the replenishment zone is connected to a replenishment pipe.
[0008] As a further embodiment of this utility model: the air inlet end of the connecting pipe is connected to the top of the isolation chamber in the rear purification zone, and the air outlet end of the connecting pipe is connected to the bottom of the isolation chamber in the adjacent front purification zone.
[0009] As a further improvement of this utility model: the inlet end of the replenishment pipe is connected to the bottom of the replenishment tank, the replenishment tank is arranged higher than the purification tank, and the top of the replenishment tank is also connected to the top of the replenishment area through the first equalizing pipe.
[0010] As a further improvement of this utility model: the bottom of the drain pipe is connected to the top of the waste liquid tank, the waste liquid tank is arranged below the purification tank, and the top of the waste liquid tank is also connected to the top of the drain area through a second pressure equalization pipe.
[0011] As a further improvement of this utility model, a servo motor for driving the partition to rotate is installed on the top of the purification box.
[0012] As a further improvement of this utility model, the outer surface of the partition is made of rubber or silicone.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Taking a configuration of four isolation chambers as an example, there are two purification zones, named Purification Zone A and Purification Zone B, and the replenishment and drainage zones are named Replenishment Zone C and D Drainage Zone, respectively. During operation, the harmful gas to be purified is supplied to the isolation chamber of Purification Zone A through the inlet pipe. After preliminary purification in Purification Zone B, the harmful gas is transported to the isolation chamber of Purification Zone B for further purification through the connecting pipe, and then discharged outwards through the exhaust pipe at the top of the isolation chamber in Purification Zone B. This achieves multi-stage purification of the harmful gas. In addition, the inner cavity of the purification chamber also includes a drainage zone and a replenishment zone. Clearly, during the multi-stage purification process, most harmful impurities are absorbed in the isolation chamber of Purification Zone A. Therefore, the saturation of the purification liquid in the isolation chamber of Purification Zone A is necessarily greater than that in the isolation chamber of Purification Zone B. When the purification liquid in Purification Zone A is saturated, the purification liquid in Purification Zone B can still maintain a good state of dissolving soluble harmful impurities. Therefore, not only is the purification liquid in Purification Zone A fully utilized, but there is also no need to reduce the flow rate of the harmful gas, ensuring efficient purification of the harmful gas.
[0015] Furthermore, when the purification liquid in purification zone A becomes supersaturated, the baffle rotates in a predetermined direction. Specifically, the supersaturated purification liquid in zone A rotates to drainage zone D for discharge, while the subsaturated purification liquid in zone B rotates to zone A for first-stage purification. New purification liquid in replenishment zone C rotates to zone B for second-stage purification, and the empty isolation chamber in drainage zone D rotates to replenishment zone C. This method eliminates the traditional method of emptying and then refilling, enabling rapid replenishment and drainage of isolation chambers in multiple purification zones. The replenishment and drainage process requires no waiting, achieving continuous purification of harmful gases and ensuring high purification efficiency.
[0016] 2. The inlet end of the connecting pipe is connected to the top of the isolation chamber in the rear purification zone, and the outlet end of the connecting pipe is connected to the bottom of the isolation chamber in the adjacent front purification zone. This ensures that when harmful gases enter the isolation chamber of each purification zone, they flow from bottom to top through the entire isolation chamber, allowing the harmful gases to fully contact the purification liquid inside the isolation chamber and ensuring that soluble harmful impurities in the harmful gases are fully absorbed.
[0017] 3. The inlet end of the replenishment pipe is connected to the bottom of the replenishment tank, which is positioned higher than the purification tank. This allows the purified liquid in the replenishment tank to be automatically transported to the isolation chamber in the replenishment area under gravity, eliminating the need for frequent pumping and sensor activation to deliver purified liquid to the isolation chamber. Furthermore, the top of the replenishment tank is connected to the top of the replenishment area via a first pressure equalization pipe to balance the pressure between the replenishment tank and the isolation chamber in the replenishment area. This ensures stable replenishment of the isolation chamber even when the replenishment tank is in a closed environment.
[0018] 4. The bottom of the drain pipe is connected to the top of the waste liquid tank. The waste liquid tank is positioned lower than the purification tank, so that the purified liquid in the isolation chamber of the drain area can be directly discharged into the waste liquid tank under the action of gravity. The top of the waste liquid tank is also connected to the top of the drain area through a second pressure equalization pipe to balance the pressure between the waste liquid tank and the isolation chamber of the drain area. Even if the waste liquid tank is in a closed environment, it can ensure the rapid and stable discharge of the purified liquid in the isolation chamber. Attached Figure Description

[0023] 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.
[0024] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:
[0025] The specific structure of this utility model is as follows: Figure 1-3 As shown, its main structure includes a purification box 10 with a cylindrical inner cavity. The inner cavity of the purification box 10 is divided by a partition 14 to form at least four isolation chambers 15 evenly distributed around the axis of the purification box 10. The partition 14 can be rotated and adjusted around the axis of the purification box 10. Along the rotation direction of the partition 14, the inner cavity of the purification box 10 is divided into a draining area, a replenishing area, and at least two purification areas corresponding to the at least four isolation chambers 15. The top of the isolation chamber 15 located in the first purification area is connected to the exhaust pipe 12, and the bottom of the isolation chamber 15 located in the last purification area is connected to the air inlet pipe 13. The isolation chambers 15 in adjacent purification areas are connected to each other through a connecting pipe 11. The bottom of the isolation chamber 15 located in the draining area is connected to the draining pipe 60, and the top of the isolation chamber 15 located in the replenishing area is connected to the replenishing pipe 50.
[0026] In actual implementation, the angle of adjustment of the partition 14 each time it rotates is related to the number of isolation chambers 15. For example, when there are four isolation chambers 15, the angle of adjustment of the partition 14 each time it rotates is 90°; when there are six isolation chambers 15, the angle of adjustment of the partition 14 each time it rotates is 60°. This ensures that after each rotation adjustment process of the partition 14, at least four isolation chambers 15 always maintain a state that corresponds one-to-one with the drainage area, the replenishment area, and at least two purification areas.
[0027] like Figure 3As shown, taking four isolation chambers 15 as an example, there are two purification zones, named A purification zone and B purification zone, and the replenishment zone and drainage zone are named C replenishment zone and D drainage zone, respectively. Before operation, the purification box 10 replenishes purification liquid into the isolation chamber 15 located in the C replenishment zone through the replenishment pipe 50. After replenishment in the C replenishment zone, the partition 14 is rotated and adjusted so that the purification zone of the C replenishment zone rotates to the B purification zone. The above operation is repeated until the isolation chambers 15 in the A purification zone, B purification zone, and C replenishment zone are all filled with purification liquid. During operation, the harmful gas to be purified is delivered to the isolation chamber 15 of the A purification zone through the air inlet pipe 13. After preliminary purification in the B purification zone, the harmful gas is delivered to the isolation chamber 15 of the B purification zone through the connecting pipe 11 for further purification, and is discharged outward through the exhaust pipe 12 at the top of the isolation chamber 15 in the B purification zone, thereby realizing multi-stage purification of harmful gases. Based on the above, the inner cavity of the purification chamber 10 is also equipped with a drain zone and a replenishment zone. Obviously, in the above multi-stage purification process, most harmful impurities will be absorbed in the isolation chamber 15 of purification zone A. Therefore, the saturation of the purified liquid in the isolation chamber 15 of purification zone A must be greater than that in the isolation chamber 15 of purification zone B. When the purified liquid in purification zone A is saturated, the purified liquid in purification zone B can still maintain a good state of dissolving soluble harmful impurities. Therefore, not only is the purified liquid in purification zone A fully utilized, but there is also no need to reduce the flow rate of harmful gases, ensuring efficient purification of harmful gases. In addition, when the purified liquid in purification zone A is oversaturated, the baffle 14 rotates and adjusts in a predetermined direction. That is, the oversaturated purified liquid in purification zone A rotates to the drain zone D for discharge, while the subsaturated purified liquid in purification zone B rotates to purification zone A to achieve the first stage of purification. The new purified liquid in replenishment zone C rotates to purification zone B for the second stage of purification, and the empty isolation chamber 15 where the drain zone D is located rotates to replenishment zone C with new purified liquid. This method abandons the traditional method of emptying and then replenishing the liquid, and realizes rapid replenishment and drainage of the isolation chamber 15 in multiple purification zones. The replenishment and drainage process does not require waiting, realizing continuous purification of harmful gases and ensuring the efficiency of harmful gas purification.
[0028] When the isolation chamber 15 is set to the gas quantity, such as Figure 1 As shown, Figure 1 With six isolation chambers 15, the total number of purification zones is four. Similarly, with six isolation chambers 15, the previous two purification zones are increased to four, transforming the process from two-stage purification to four-stage purification, ensuring that soluble harmful substances in the gases are fully dissolved and purified. The same principle applies when five or seven isolation chambers 15 are used, but the number of times this occurs will not be elaborated further.
[0029] Based on the above, such as Figure 1 and Figure 2 As shown, the inlet end of the connecting pipe 11 connects to the top of the isolation chamber 15 in the rear purification zone, and the outlet end of the connecting pipe 11 connects to the bottom of the isolation chamber 15 in the adjacent front purification zone. Taking the state after harmful gas enters the bottom of the isolation chamber 15 in the rear purification zone through the inlet pipe 13 as an example, the harmful gas will enter the connecting pipe 11 from its top, and then enter the bottom of the isolation chamber 15 in the adjacent front purification zone from its outlet end along the inner cavity of the connecting pipe 11. That is, when the harmful gas enters the isolation chamber 15 in each purification zone, it will flow from bottom to top through the entire isolation chamber 15, so that the harmful gas and the purification liquid in the isolation chamber 15 are in full contact, ensuring that the soluble harmful impurities in the harmful gas are fully absorbed.
[0030] Based on the above, such as Figure 2 As shown, the inlet end of the replenishment pipe 50 is connected to the bottom of the replenishment tank 20, which is positioned higher than the purification tank 10. This allows the purified liquid in the replenishment tank 20 to be automatically transported to the isolation chamber 15 in the replenishment area under gravity, eliminating the need for frequent pumping and sensor activation to deliver purified liquid to the isolation chamber 15. Furthermore, the top of the replenishment tank 20 is connected to the top of the replenishment area via a first equalizing pipe 21 to balance the pressure between the replenishment tank 20 and the isolation chamber 15. Even in a closed environment, this ensures stable replenishment of the replenishment tank 20 to the isolation chamber 15. Alternatively, in practice, a water pump can be used to replenish the purified liquid into the isolation chamber 15 via the replenishment pipe 50. During replenishment, care must be taken to ensure that the purified liquid does not completely fill the inner cavity of the replenishment pipe 50, leaving a channel for the gas in the isolation chamber 15 to escape.
[0031] Based on the above, such as Figure 2 As shown, the bottom of the drain pipe 60 is connected to the top of the waste liquid tank 30. The waste liquid tank 30 is positioned lower than the purification tank 10, allowing the purified liquid in the isolation chamber 15 at the drain area to be directly discharged into the waste liquid tank 30 under gravity. The top of the waste liquid tank 30 is also connected to the top of the drain area via a second pressure equalization pipe 31, used to equalize the pressure between the waste liquid tank 30 and the isolation chamber 15 at the drain area. Even if the waste liquid tank 30 is in a closed environment, it ensures rapid and stable discharge of the purified liquid in the isolation chamber 15. Of course, in actual implementation, gas can also be added to the isolation chamber 15 through the drain pipe 60 to pressurize it, achieving rapid discharge of the purified liquid in the isolation chamber 15.
[0032] In addition, such as Figure 2 As shown, a servo motor 40 is installed on the top of the purification chamber 10 to drive the partition 14 to rotate, ensuring that the angle of rotation of the partition 14 is accurate and reliable each time. In actual implementation, the partition 14 can also be driven by a manual handwheel or a stepper motor.
[0033] Based on the above, the outer surface of the partition 14 is made of rubber or silicone material. Compared with the rigid sealing method using rigid material, the rigid sealing method of the partition 14 results in a better sealing effect between adjacent isolation cavities 15.
[0034] It is worth mentioning that valves will be equipped on the aforementioned connecting pipe 11, exhaust pipe 12, air inlet pipe 13, first equalizing pipe 21, second equalizing pipe 31, replenishing pipe 50 and drain pipe 60 according to actual needs, so as to facilitate the control of the pipeline during subsequent maintenance.
[0035] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
