[0028] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the specification.
[0029] In the related art, the chemical production process of synthesizing ammonia and the like produces waste gas-ammonia, and because the amount of ammonia emitted is small, a temporary water bucket is usually connected for absorption.
[0030] However, the temporary water bucket is prone to ammonia gas escape due to ammonia water saturation.
[0031] In view of the above technical problems, the ammonia gas treatment system provided by the present disclosure is connected with a first control pipeline and a first detection port, and the absorption bucket contains an absorption medium (such as desalted water). Ammonia gas can enter the absorption bucket through the first control pipeline and be absorbed by the absorption medium in the absorption bucket. During the absorption of ammonia gas in the absorption bucket, the first detection port can be used to detect whether the absorption in the absorption bucket is saturated. If it is saturated, the first valve of the first control pipeline can be used to control the stop of ammonia gas delivery into the absorption bucket, so as to reduce the situation of ammonia gas escape due to ammonia water saturation in the absorption bucket.
[0032] Referring to Figure 1 and Figure 2As shown, the ammonia treatment system 10 can include an absorption barrel 11, a first control pipeline 12 and a second control pipeline 13. The absorption barrel 11 is provided with an inlet 111 and an outlet 112, and is used to accommodate an absorption medium. The first control pipeline 12 includes a first pipe body 121, a second pipe body 122 and a first control valve 123. Two ends of the second pipe body 122 are respectively connected to one end of the first pipe body 121 and the inlet 111 of the absorption barrel 11. The hardness of the second pipe body 122 is greater than that of the first pipe body 121. The first control valve 123 is arranged on the second pipe body 122 to control the working state of the second pipe body 122. The second control pipeline 13 includes a third pipe body 131, a fourth pipe body 132 and a second control valve 133. Two ends of the third pipe body 131 are respectively connected to the outlet 112 of the absorption barrel 11 and one end of the fourth pipe body 132. The hardness of the third pipe body 131 is greater than that of the fourth pipe body 132. The second control valve 133 is arranged on the third pipe body 131 to control the working state of the third pipe body 131. The absorption barrel 11 is further provided with a first detection port (not shown in the figure). When the absorption medium in the first detection port meets a target condition, the first control valve 123 controls the second pipe body 122 to be in a non-working state.
[0033] The absorption barrel 11 can at least accommodate an absorption medium, such as desalted water 20 that can absorb ammonia. The absorption barrel 11 can be made of a material with corrosion resistance, high temperature resistance and the like, so as to reduce the corrosion probability of the absorption barrel 11 and adapt to high temperature environment. The inlet 111 of the absorption barrel 11 can be a circular, rectangular, pentagonal or the like opening. The outlet 112 of the absorption barrel 11 can be a circular, rectangular, pentagonal or the like opening. The absorption medium in the absorption barrel 11 can be injected into the absorption barrel 11 through the inlet 111 or the outlet 112 of the absorption barrel 11. The absorption barrel 11 is provided with a first detection port. The absorption medium in the first detection port can be detected. When the detector meets a target condition (such as ammonia concentration exceeding the standard, desalted water 20 saturation), the ammonia gas supply to the absorption barrel 11 is stopped.
[0034] The first control pipeline 12 is connected with the inlet 111 of the absorption bucket 11 at least, so as to control the ammonia gas entering the absorption bucket 11 at least, such as controlling the ammonia gas to start to be delivered, controlling the ammonia gas to stop to be delivered, controlling the delivery speed of the ammonia gas to be reduced, etc. The first pipe body 121 and the second pipe body 122 are different in hardness, and the second pipe body 122 with greater hardness is located between the first pipe body 121 with smaller hardness and the absorption bucket 11, so that the deformation probability of the second pipe body 122 connected with the absorption bucket 11, such as distortion and bending, can be reduced, so as to reduce the situation that the ammonia gas cannot normally enter the absorption bucket 11, and the first pipe body 121 can be a hose, so as to be bent to the ammonia gas at different positions, and the ammonia gas at different positions can be treated; the connection between the second pipe body 122 and the absorption bucket 11 can be sealed by a sealing ring or the like, so as to reduce the probability that the ammonia gas leaks from the gap between the second pipe body 122 and the absorption bucket 11. The first control valve 123 is arranged on the second pipe body 122, so as to control the ammonia gas entering the absorption bucket 11, such as controlling the ammonia gas to start to be delivered, controlling the ammonia gas to stop to be delivered, controlling the delivery speed of the ammonia gas to be reduced, etc.; the first control valve 123 can be a manual switch, can be a remote control switch, or can be other settings.
[0035] A second control pipeline 13 is connected with at least the outlet 112 of the absorption barrel 11, so as to guide at least the gas and / or liquid flowing out of the absorption barrel 11. For example, after the desalted water 20 in the absorption barrel 11 absorbs the ammonia gas, the ammonia water is discharged through the second control pipeline 13. In the case that the second control pipeline 13 is used for discharging the ammonia water, the second control pipeline 13 can be provided with a pump, or the outlet 112 of the absorption barrel 11 can be located at the bottom end of the absorption barrel 11, so that the ammonia water in the absorption barrel 11 can enter the second control pipeline 13. For another example, the ammonia gas treatment system 10 comprises a first absorption structure 14 and a second absorption structure 15. The first absorption structure 14 can comprise the absorption barrel 11, the first control pipeline 12 and the second control pipeline 13. The second absorption structure 15 can also comprise the absorption barrel 11, the first control pipeline 12 and the second control pipeline 13. The first control pipeline 12 of the second absorption structure 15 is connected with the second control pipeline 13 of the first absorption structure 14, so that the second control pipeline 13 of the first absorption structure 14 can guide the ammonia gas not absorbed in the absorption barrel 11 of the first absorption structure 14 into the absorption barrel 11 of the second absorption structure 15 for further absorption, so as to further reduce the situation that the ammonia water is saturated and the ammonia gas escapes. The third pipe body 131 and the fourth pipe body 132 have different hardnesses, and the third pipe body 131 with greater hardness is located between the absorption barrel 11 and the fourth pipe body 132. In this way, the probability of deformation, such as twisting and bending, of the third pipe body 131 connected with the absorption barrel 11 can be reduced, so as to reduce the situation that the ammonia gas and the ammonia water cannot normally flow out of the absorption barrel 11. The fourth pipe body 132 can be a flexible pipe, so as to be bent to different positions, thereby guiding the ammonia gas and the ammonia water to different positions. The third pipe body 131 and the absorption barrel 11 can be sealed by a sealing ring or the like, so as to reduce the probability of leakage of the ammonia gas and the ammonia water from the gap between the third pipe body 131 and the absorption barrel 11. The second control valve 133 can control the ammonia gas or the ammonia water flowing out of the outlet 112 of the absorption barrel 11, such as controlling the start of output of the ammonia gas / ammonia water, controlling the stop of output of the ammonia gas / ammonia water, controlling the reduction of the output speed of the ammonia gas / ammonia water, and the like. The second control valve 133 can be a manual switch, a remote control switch or other settings.
[0036] In an example, referring to Figure 1As shown, the ammonia treatment system 10 can include an absorption barrel 11, a first control pipeline 12 and a second control pipeline 13. The absorption barrel 11 is provided with an inlet 111 and an outlet 112, and is used to accommodate desalted water 20. The first control pipeline 12 can include a first pipe body 121, a second pipe body 122 and a first control valve 123. The two ends of the second pipe body 122 are respectively connected to one end of the first pipe body 121 and the inlet 111 of the absorption barrel 11. The hardness of the second pipe body 122 is greater than that of the first pipe body 121. The first control valve 123 is arranged on the second pipe body 122 to control the working state of the second pipe body 122. The second control pipeline 13 can include a third pipe body 131, a fourth pipe body 132 and a second control valve 133. The two ends of the third pipe body 131 are respectively connected to the outlet 112 of the absorption barrel 11 and one end of the fourth pipe body 132. The hardness of the third pipe body 131 is greater than that of the fourth pipe body 132. The second control valve 133 is arranged on the third pipe body 131 to control the working state of the third pipe body 131. The absorption barrel 11 is also provided with a first detection port. When the absorption medium in the first detection port meets the target condition, the first control valve 123 controls the second pipe body 122 to be in a non-working state.
[0037] In an example, the ammonia treatment system 10 can include a first absorption structure 14 and a second absorption structure 15. The first absorption structure 14 can have an absorption barrel 11, a first control pipeline 12 and a second control pipeline 13. The second absorption structure 15 also has an absorption barrel 11, a first control pipeline 12 and a second control pipeline 13. The first control pipeline 12 of the second absorption structure 15 is connected to the second control pipeline 13 of the first absorption structure 14. The first detection port of the absorption barrel 11 of the first absorption structure 14 can be opened for absorption saturation detection. The first detection port of the absorption barrel 11 of the second absorption structure 15 cannot be opened. When the absorption medium in the first detection port of the absorption barrel 11 of the first absorption structure 14 meets the target condition, the first control valve 123 of the first absorption structure 14 controls the corresponding second pipe body 122 to be in a non-working state. The first detection port of the first absorption structure 14 can be opened while the first detection port of the second absorption structure 15 cannot be opened. In this way, when the absorption barrel 11 of the first absorption structure 14 is saturated, it can be removed in time, thereby reducing the situation of ammonia escape caused by the saturation of the first absorption structure 14 and the second absorption structure 15.
[0038] In the embodiment, the ammonia treatment system 10 can include an absorption barrel 11, a first control pipeline 12 and a second control pipeline 13, the inlet 111 and the outlet 112 of the absorption barrel 11 are connected with the first control pipeline 12 and the second control pipeline 13 respectively, the first control pipeline 12 can control whether the ammonia gas enters the absorption barrel 11, the second control pipeline 13 can control whether the ammonia gas and / or the ammonia water in the absorption barrel 11 is sent out from the outlet 112 of the absorption barrel 11, and in the process of absorption, the absorption medium at the position of the first detection port can be detected by the first detection port to confirm whether there is an absorption saturation condition in the absorption barrel 11, if there is, the first control valve 123 of the first control pipeline 12 can be controlled to stop delivering the ammonia gas into the absorption barrel 11, so as to reduce the situation of ammonia gas escaping due to the saturation of the ammonia water in the absorption barrel 11.
[0039] In some embodiments, as shown in Figure 1 and Figure 2 , the first pipe body 121 and the fourth pipe body 132 can be bent, and the second pipe body 122 and the third pipe body 131 cannot be bent. In this way, the first pipe body 121 can send the ammonia gas at different positions into the absorption barrel 11, and the fourth pipe body 132 can guide the ammonia gas and / or the ammonia water in the absorption barrel 11 to different positions, while the second pipe body 122 and the third pipe body 131 cannot be bent, so as to make the ammonia gas or the ammonia water in the pipelines near the inlet 111 and the outlet 112 of the absorption barrel 11 flow more smoothly.
[0040] In some embodiments, as shown in Figure 1 and Figure 2 , the position of the outlet 112 of the absorption barrel 11 is higher than the position of the inlet 111 of the absorption barrel 11; the position of the first detection port is higher than the position of the outlet 112 of the absorption barrel 11, or the position of the first detection port is near the position of the inlet 111 of the absorption barrel 11.
[0041] In the case that the absorption barrel 11 is injected with a liquid absorption medium such as desalted water 20, the liquid absorption medium is located at the lower end of the absorption barrel 11 under the action of gravity, and the position of the outlet 112 of the absorption barrel 11 is higher than the position of the inlet 111 of the absorption barrel 11, so that after the ammonia gas enters through the inlet 111 of the absorption barrel 11, it is closer to the liquid absorption medium in the absorption barrel 11, so as to be absorbed by the liquid absorption medium more quickly and more, thereby improving the absorption efficiency and absorption effect; further, the ammonia gas not absorbed by the liquid absorption medium moves upward and can be sent to the second absorption structure 15 through the outlet 112.
[0042] When the first detection port is positioned higher than the outlet 112 of the absorption tank 11, the presence of ammonia saturation in the absorption tank 11 can be confirmed by detecting whether the ammonia concentration at the first detection port exceeds the standard. Since the first detection port is higher than the outlet 112, the probability of saturation at the first detection port being the entire space within the absorption tank 11 is greater. In this case, the supply of ammonia to the absorption tank 11 can be stopped to reduce the risk of ammonia escape due to absorption saturation. When the first detection port is positioned near the inlet 111 of the absorption tank 11, the presence of absorption medium concentration exceeding the standard can be used to confirm whether absorption saturation has occurred in the absorption tank 11. These two settings for the first detection port can be flexibly selected and configured as needed during implementation.
[0043] In some embodiments, see Figure 1 and Figure 2 As shown, the first pipe body 121 and the second pipe body 122 are connected by a first connector 124, and the first connector 124 has a disconnectable first sub-connector (not shown) and a second sub-connector (not shown); the third pipe body 131 and the fourth pipe body 132 are connected by a second connector 134, and the second connector 134 has a disconnectable third sub-connector (not shown) and a fourth sub-connector (not shown).
[0044] Alternatively, the first tube 121 can be connected to one of a first sub-connector and a second sub-connector, and the second tube 122 can be connected to the other of the first and second sub-connectors. The first and second sub-connectors can be connected to connect the first tube 121 and the second tube 122, and the first and second sub-connectors can be disconnected to prevent communication between the first tube 121 and the second tube 122. Similarly, the third tube 131 can be connected to one of a third sub-connector and a fourth sub-connector, and the fourth tube 132 can be connected to the other of the third and fourth sub-connectors. The third and fourth sub-connectors can be connected to connect the third tube 131 and the fourth tube 132, and the third and fourth sub-connectors can be disconnected to prevent communication between the third tube 131 and the fourth tube 132. Thus, a first tube 121 can be connected to different second tubes 122, and a third tube 131 can be connected to different fourth tubes 132, allowing for flexible assembly.
[0045] Here, the first sub-joint and the second sub-joint can be connected through the cooperation of internal and external threads, can be connected through interference fit, can be connected through clamping, or can be connected through other connection methods. Similarly, the third sub-joint and the fourth sub-joint can be connected through the cooperation of internal and external threads, can be connected through interference fit, can be connected through clamping, or can be connected through other connection methods.
[0046] In some embodiments, referring to Figure 2 The ammonia treatment system 10 can further include a first absorption structure 14, a second absorption structure 15, and a third absorption structure 16. The first absorption structure 14 has an absorption barrel 11, a first control pipeline 12, and a second control pipeline 13. The second absorption structure 15 has an absorption barrel 11, a first control pipeline 12, and a second control pipeline 13. The first control pipeline 12 of the second absorption structure 15 is connected to the second control pipeline 13 of the first absorption structure 14. The third absorption structure 16 has an absorption barrel 11, a first control pipeline 12, and a second control pipeline 13. The first control pipeline 12 of the third absorption structure 16 is connected to the second control pipeline 13 of the second absorption structure 15. Alternatively, the ammonia treatment system 10 includes the first absorption structure 14, the second absorption structure 15, and the third absorption structure 16 connected in sequence. Each absorption structure is provided with an absorption barrel 11. The absorption barrel 11 is provided with an absorption medium. In this way, the amount of absorption medium is increased, and more ammonia can enter the first absorption structure 14, the second absorption structure 15, and the third absorption structure 16 in sequence to be absorbed, thereby improving the absorption efficiency and reducing the probability of ammonia escaping without being absorbed.
[0047] The first absorption structure 14, the second absorption structure 15, and the third absorption structure 16 can have the same structure as shown in Figure 2 to simplify the manufacturing process and reduce the manufacturing cost.
[0048] In some embodiments, referring to Figure 2 When the first detection port of the first absorption structure 14 is in a detection state, the first detection port of the second absorption structure 15 and the first detection port of the third absorption structure 16 are in a closed state. When it is confirmed through detection that the absorption barrel 11 of the first absorption structure 14 is saturated, the first absorption structure 14 can be removed. At the same time, the second absorption structure 15 can be used as the first absorption structure, and the third absorption structure 16 can be used as the second absorption structure for ammonia absorption. In this way, the ammonia water in the removed first absorption structure 14 can be replaced with desalted water 20 and connected to the third absorption structure 16 for circulation. The ammonia absorption can be performed through the circulation of the first absorption structure 14, the second absorption structure 15, and the third absorption structure 16, and the waste of desalted water 20 can be reduced.
[0049] Here, by detecting the saturation of the first absorption structure 14 directly connected to the ammonia, the probability of ammonia escaping due to absorption saturation of the first absorption structure 14, the second absorption structure 15 and the third absorption structure 16 can be reduced, and each of the first absorption structure 14, the second absorption structure 15 and the third absorption structure 16 is provided with a first detection port, so that the first absorption structure located at the first position and directly connected to the ammonia can be replaced with absorption medium after absorption saturation and connected to the tail end of the absorption structure, thereby circulating through the first absorption structure 14, the second absorption structure 15 and the third absorption structure 16 to absorb ammonia, so as to reduce the number of absorption structures and reduce the cost.
[0050] In some embodiments, referring to Figure 2 When the absorption medium of the first detection port of the first absorption structure 14 meets the target condition, the first control valve 123 of the second absorption structure 15 controls the second pipe body 122 of the second absorption structure 15 to be in an inactive state, and the first absorption structure 14 and the second absorption structure 15 are disconnected. That is, when the absorption barrel 11 of the first absorption structure 14 is saturated, the second control valve 133 of the second absorption structure 15 can control the transmission of ammonia between the absorption barrel 11 of the first absorption structure 14 and the absorption barrel 11 of the second absorption structure 15, and the first absorption structure 14 and the second absorption structure 15 can be disconnected, so that the second absorption structure 15 can directly contact the ammonia as the first absorption structure, so as to further use the desalted water 20 in the absorption barrel 11 of the second absorption structure 15 and the third absorption structure 16 for absorption, so as to reduce the waste of the desalted water 20 in the second absorption structure 15.
[0051] In some embodiments, referring to Figure 2 When the first control valve 123 of the second absorption structure 15 controls the second pipe body 122 of the second absorption structure 15 to be in an inactive state, the first pipe body 121 of the first absorption structure 14 can be connected to the fourth pipe body 132 of the third absorption structure 16. That is, when the first absorption structure 14 and the second absorption structure 15 are disconnected, the ammonia in the absorption barrel 11 of the first absorption structure 14 is replaced with desalted water 20, and then the first absorption structure 14 is connected to the third absorption structure 16 for absorption, so that the three absorption structures can be continuously used for absorption.
[0052] In some embodiments, the ammonia treatment system 10 can further comprise a concentration detector (not shown in the figure) in communication with the first detection port; in the case that the position of the first detection port is higher than the position of the outlet 112 of the absorption barrel 11, the concentration detector is used to detect the ammonia concentration; in the case that the position of the first detection port is adjacent to the position of the inlet 111 of the absorption barrel 11, the concentration detector is used to detect the absorption medium concentration. That is, whether the ammonia concentration at the position of the first detection port exceeds the standard or the absorption medium concentration exceeds the standard due to absorbing too much ammonia can be detected by the concentration detector connected to the first detection port, and if it exceeds the standard, it can be confirmed that the corresponding absorption barrel 11 has been saturated and needs to be replaced, so that the saturation information of the absorption barrel 11 can be obtained in time by the concentration detector.
[0053] In some embodiments, the absorption barrel 11 can further be provided with a second detection port (not shown in the figure), the position of the second detection port is higher than the position of the outlet 112 of the absorption barrel 11, and the second detection port is in an always-open state; if a small amount of ammonia is found in the second detection port (such as smelling ammonia), it indicates that the absorption barrel 11 is saturated, and the replacement of the desalted water 20 and other work can be carried out in time to reduce the probability of ammonia escaping.
[0054] In some embodiments, the absorption barrel 11 can further be provided with a second detection port (not shown in the figure), the position of the second detection port is lower than the position of the outlet 112 of the absorption barrel 11; the ammonia treatment system 10 can further comprise a gas collector (not shown in the figure) in communication with the second detection port and used to detect whether there is ammonia in the second detection port. That is, by detecting ammonia at a position lower than the outlet 112, if there is ammonia, it indicates that the absorption barrel 11 is about to be saturated, and the replacement of the desalted water 20 and other work can be carried out in time to reduce the probability of ammonia escaping.
[0055] In the case that the ammonia treatment system 10 comprises two or more absorption structures, the gas collector can be arranged on the last absorption structure to reduce the number of gas collectors and reduce costs; for example, in the case that the ammonia treatment system 10 comprises a first absorption structure 14, a second absorption structure 15 and a third absorption structure 16, and the first absorption structure 14 is directly connected to ammonia, the gas collector is connected to the second detection port of the third absorption structure 16, and after the order of the multiple absorption structures is adjusted, the gas collector can be adjusted to the last absorption structure.
