DETAILED DESCRIPTION
[0027] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only a part of the embodiments of the present application, not all the embodiments.
[0029] As shown in Figure 1 The catalyst excessive impregnation reminding device provided by the embodiment of the present application includes a circulating pipeline 1, a detection piece 2 and a reminding piece 3. The circulating pipeline 1 is used for being connected to a catalyst impregnation equipment, so that the impregnation liquid flows in the circulating pipeline 1. Specifically, the circulating pipeline 1 has a liquid inlet end and a liquid outlet end. The catalyst impregnation equipment is provided with a liquid outlet and a liquid inlet. The liquid inlet is arranged at the top of the catalyst impregnation equipment. The liquid inlet end of the circulating pipeline 1 is in communication with the liquid outlet of the catalyst impregnation equipment, and the liquid outlet end of the circulating pipeline 1 is in communication with the liquid inlet of the catalyst impregnation equipment, so that the impregnation liquid in the catalyst impregnation equipment can flow into the circulating pipeline 1 through the liquid outlet, and then flow back into the catalyst impregnation equipment through the liquid inlet.
[0030] The detection member 2 is used to detect the turbidity of the impregnation liquid flowing in the circulation pipeline 1, wherein the impregnation liquid carries the carrier, and when the carrier gradually starts to fall off during the impregnation process, the turbidity of the impregnation liquid will increase. In the application, the detection member 2 and the reminding member 3 are configured such that when the detection member 2 detects that the turbidity of the impregnation liquid flowing in the circulation pipeline 1 reaches a preset turbidity, the reminding member 3 sends an alarm signal.
[0031] The reminding device provided by the utility model can lead the impregnation liquid in the catalyst impregnation equipment out, and detect the turbidity of the impregnation liquid through the detection member 2. When the carrier is normally impregnated, the carrier starts to fall off, and the turbidity of the impregnation liquid slowly increases within a certain range. When the carrier has a tendency of excessive impregnation, the falling off of the carrier will cause the turbidity of the impregnation liquid to be greater than the preset turbidity. When the detection member 2 detects that the turbidity of the impregnation liquid is greater than the preset turbidity, the reminding member 3 sends an alarm signal to remind the staff to take corresponding operation, so as to avoid the phenomenon of excessive impregnation of the carrier and ensure that the performance of the catalyst meets the demand.
[0032] The catalyst applicable to the reminding device provided by the utility model can be hydrogenation catalyst and the like. It can be understood that the reminding device can also be applicable to other catalysts that can be detected.
[0033] In some embodiments, as shown in Figure 1 The detection member 2 includes a photosensitive coating 21 and a light source 22, wherein the photosensitive material refers to a sensitive material whose characteristic parameters obviously change with the change of external light radiation. The photosensitive property of the photosensitive material is excited when the light intensity changes, which is a conventional technology in the field. The light source 22 is a device capable of producing light, which is a conventional technology in the field.
[0034] The photosensitive coating 21 is arranged on one side of the circulation pipeline 1, and the circulation pipeline 1 is made of transparent material at least at the position where the photosensitive coating 21 is arranged. The light source 22 is arranged on the side of the circulation pipeline 1 away from the photosensitive coating 21, so that the light source 22 and the photosensitive coating 21 are opposite to each other, and the line connecting the two passes through the transparent position of the circulation pipeline 1, so that the light source 22 irradiates the photosensitive coating 21 through the circulation pipeline 1 and the impregnation liquid in the circulation pipeline 1. And configured to: when the light intensity received by the photosensitive coating 21 is lower than the preset light intensity, the reminding member 3 sends an alarm.
[0035] Specifically, when the carrier in the impregnation liquid is in the normal impregnation process, the carrier begins to fall powder, the light transmittance of the impregnation liquid gradually decreases, the light intensity received by the photosensitive coating 21 is within a certain range, and the photosensitive coating 21 cannot trigger the alarm piece when it receives the light intensity within the range. During the impregnation process, the light intensity transmitted through the impregnation liquid gradually decreases until the impregnation is completed, and the light intensity transmitted through the impregnation liquid decreases to a certain specific value (preset light intensity). At this time, the light intensity received by the photosensitive coating 21 is lower than the preset light intensity, the photosensitive coating 21 triggers the alarm piece, and the alarm piece alarms to remind the staff that the impregnation is completed, so as to avoid the phenomenon of excessive impregnation.
[0036] Whether the photosensitive coating 21 triggers the alarm piece is based on the logic circuit 7, and the basic principle is based on the change of the light transmittance of the impregnation liquid. The impregnation liquid is irradiated by the irradiation light with a certain light intensity. If the light transmittance of the impregnation liquid changes, the light intensity transmitted through the impregnation liquid will also change. The light transmitted through the impregnation liquid is projected onto the photosensitive material. The photosensitive material converts the change of brightness into an electrical signal and inputs it into the logic circuit connected thereto. The logic circuit transmits the electrical signal to the related electronic elements to make them emit light, sound or further transmit the electrical signal. Under certain conditions, the way of triggering the alarm piece based on the logic circuit 7 is a mature technology in the art, which is not described in detail here.
[0037] The detection piece 2 in this design has a simple structure and can accurately reflect the impregnation condition of the carrier according to the light intensity received by the photosensitive coating 21. The measurement result is accurate, and the alarm piece can be triggered in time after the impregnation is completed, so as to avoid the problems of serious carrier powdering and serious loss of active components caused by excessive impregnation of the carrier.
[0038] In some embodiments, the circulating pipeline 1 is made of transparent material as a whole, so that the circulating pipeline 1 is more convenient to manufacture, and the staff can observe the flow condition of the impregnation liquid in the circulating pipeline 1.
[0039] In some embodiments, as shown in Figure 1 The catalyst excessive impregnation reminding device further comprises a mixing assembly 4, which is arranged on the circulating pipeline 1 and located on the side of the detection piece 2 close to the catalyst impregnation equipment.
[0040] Specifically, the circulating pipeline 1 has an inlet end and an outlet end. The inlet end of the circulating pipeline 1 communicates with the liquid outlet of the catalyst impregnation equipment, and the outlet end of the circulating pipeline 1 communicates with the liquid inlet of the catalyst impregnation equipment. The mixing assembly 4 is connected to the circulating pipeline 1, so that the impregnation liquid flowing out of the catalyst impregnation equipment enters the circulating pipeline 1, flows into the mixing assembly 4, mixes in the mixing assembly 4, and then flows into the circulating pipeline 1. After the turbidity of the impregnation liquid is detected by the detection piece 2, the impregnation liquid flows back to the catalyst impregnation equipment through the outlet of the circulating pipeline 1.
[0041] In this design, the mixed assembly 4 can mix the immersion liquid flowing to the detection member 2, increase the mixing effect of the immersion liquid, ensure the uniform distribution of solid-liquid components in the immersion liquid before the detection of the detection member 2, and further ensure the accuracy of the detection result of the detection member 2, so that the reminding device has a correction function.
[0042] In some embodiments, in combination with Figure 2 and Figure 3 As shown in the figure, the mixed assembly 4 includes a mixing box 41 arranged on the circulating pipeline 1, and a stirring cylinder 42 is arranged inside the mixing box 41. The outer periphery of the stirring cylinder 42 is uniformly distributed with a plurality of stirring protrusions 421.
[0043] Specifically, the outer periphery of the mixing box 41 near the top thereof is provided with a liquid inlet, and the outer periphery of the mixing box 41 near the bottom thereof is provided with a liquid outlet. The liquid inlet of the mixing box 41 is in communication with part of the circulating pipeline 1, and the liquid outlet of the mixing box 41 is in communication with another part of the circulating pipeline 1, so as to connect the mixing box 41 to the circulating pipeline 1. The inside of the mixing box 41 is provided with the stirring cylinder 42, and the stirring cylinder 42 is coaxially arranged with the mixing box 41. The stirring cylinder 42 can actively or passively rotate relative to the mixing box 41, so as to stir the immersion liquid through the stirring protrusions 421 on the outer periphery of the stirring cylinder 42, and ensure the uniform distribution of solid-liquid components in the immersion liquid.
[0044] The mixed assembly 4 in this design has a simple structure and can uniformly stir the immersion liquid, meet the mixing requirements of the immersion liquid before detection, and ensure the accuracy of the detection result of the detection member 2.
[0045] In some embodiments, the mixed assembly 4 further includes a driving member arranged on the top of the mixing box 41, and the driving member is used to drive the stirring cylinder 42 to rotate. The driving member can be a driving motor, or a combination of a driving motor and a speed reducer, which can be selected according to actual requirements.
[0046] In this design, the driving member can drive the stirring cylinder 42 to actively rotate, so as to stir the immersion liquid entering the stirring cylinder 42 through the stirring cylinder 42 and the stirring protrusions 421, and the stirring frequency of the immersion liquid can be controlled by the driving member, so as to ensure the stirring effect of the immersion liquid.
[0047] In some embodiments, as shown in the figure, Figure 2 The bottom section of the mixing box 41 is in the shape of an inverted cone, and the bottom section of the stirring cylinder 42 is also in the shape of an inverted cone. The non-inverted-cone-shaped part of the mixing cavity is in the shape of a cylinder, i.e., the inner cavity section of the non-inverted-cone-shaped part of the mixing cavity is in the shape of a rectangle, so as to increase the cavity range of the mixing box 41.
[0048] In this design, the inner cavity of the mixing box 41 matches the structure of the stirring cylinder 42, and the conical design of the bottom can generate a cyclone, ensuring the stirring effect of the impregnation liquid.
[0049] In some embodiments, the liquid outlet of the mixing box 41 is arranged at the intersection of the cylindrical portion and the inverted conical portion of the mixing box 41.
[0050] In this design, the liquid outlet of the mixing box 41 is arranged at the bottom of the mixing box 41, which avoids the impregnation liquid in the un-mixed part of the bottom of the mixing box 41 from flowing out, thereby ensuring that the impregnation liquid in the mixed state flows out of the liquid outlet of the mixing box 41, and ensuring the uniformity of the flowing impregnation liquid.
[0051] In some embodiments, as shown in Figure 1 The liquid inlet end of the circulating pipeline 1 is connected to a plurality of branch pipes 11, and the liquid inlet ends of the plurality of branch pipes 11 are respectively used to communicate with a plurality of liquid outlets on the catalyst impregnation device, which are arranged at intervals along the vertical direction.
[0052] In this design, it is convenient to sample the impregnation liquid at different positions of the catalyst impregnation device, so that the impregnation liquid at each position flows into the detection position after mixing, further increasing the accuracy of the detection result.
[0053] In some embodiments, continuing to refer to Figure 1 The catalyst impregnation device is provided with three liquid outlets, which are respectively arranged at the upper part of the catalyst impregnation device, the middle part of the catalyst impregnation device, and the lower part of the catalyst impregnation device.
[0054] In some embodiments, the catalyst over-impregnation reminding device further comprises a circulating pump 5, which is arranged between the liquid inlet end of the circulating pipeline 1 and the mixing assembly 4.
[0055] In this design, the circulating pump 5 can provide power for the circulation of the impregnation liquid, ensuring the flow effect of the impregnation liquid. And by controlling the circulating pump 5 to select the opening time and opening mode (continuous opening or intermittent opening) of the circulating pipeline 1, the operation convenience is increased.
[0056] In some embodiments, the reminding member 3 can emit a sound alarm signal, and / or a light alarm signal, and / or a remote electrical signal. The remote electrical signal can be displayed on a remote terminal, so that the staff at the corresponding position can receive the reminder.
[0057] In this design, the staff can be reminded by sound, light, and remote electrical signal. One or more of them can be selected according to actual needs, ensuring that the staff can receive the reminder.
[0058] AsFigure 1 The utility model also provides a kind of catalyst impregnation equipment shown, including impregnation equipment body 6 and the above-mentioned catalyst excessive impregnation reminding device of being arranged on impregnation equipment body 6, the liquid inlet end of the circulation pipeline 1 of catalyst excessive impregnation reminding device is communicated with the liquid outlet of impregnation equipment body 6, the liquid outlet end of circulation pipeline 1 is communicated with the liquid inlet of impregnation equipment body 6, to realize that impregnation liquid in impregnation equipment body 6 circulates in circulation pipeline 1 flow.The catalyst excessive impregnation reminding device in this place includes the whole technical features of the above-mentioned catalyst excessive impregnation reminding device.
