Description

TECHNICAL FIELD

[0002] The high-throughput parallel reaction system is widely used in chemical reaction research, and a plurality of reactors are arranged in parallel in the system, and the reactors are usually flow-through reactors. In order to compare and analyze the experimental results performed in different reactors, it is crucial to accurately control the process conditions such as temperature, pressure and space velocity of each reactor.

[0003] When a certain compound can be synthesized by using a conventional small fixed bed / fluidized bed reactor, in order to carry out small-scale production, a plurality of such small reactors are arranged in parallel. The reaction conditions such as pressure used in these parallel reactors should be the same as the original single reactor, and it is the key to scale synthesis of the compound to ensure that the reaction conditions in all reactors are the same.

[0004] The pressure regulation control of the conventional reaction system is realized by a back pressure valve arranged at the outlet of the reactor, and each reactor channel needs to be provided with a corresponding back pressure valve, which is obviously not conducive because the back pressure valve usually has high cost and occupies a large space.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0051] The existing high-throughput pressure controller needs to be provided with a back pressure valve at each reactor outlet, which causes problems of high equipment cost and large space occupation.

[0052] To solve the above problems, the following embodiments are provided:

[0053] Embodiment 1: refer to Figure 1 as shown, Figure 1 which is a schematic view of the high-throughput pressure controller of Embodiment 1.

[0054] The embodiment provides a high-throughput pressure controller, comprising: a first layer plate 1, a second layer plate 2, a sealing member 3 and a movable member 4.

[0055] The first layer plate 1 is provided with an inflow channel 11 and an outflow channel 12.

[0056] The first layer plate 1 can be made of stainless steel, or can be made of materials such as Hastelloy and titanium alloy according to specific experimental requirements; the inflow channel 11 is used for inputting reaction fluid, and can be connected to a reaction fluid supply pipeline or a reactor outlet pipeline of a parallel reaction system; the outflow channel 12 is used for outputting reaction fluid, and can be connected to a reactor inlet pipeline or a detection and analysis inlet of a parallel reaction system; wherein the first layer plate 1 can increase the number of layers according to the actual flow path requirements of high-throughput, for simultaneous input of multiple reaction fluids.

[0057] The second layer plate 2 is provided with a balance flow channel 20.

[0058] The second layer plate 2 can be made of stainless steel, or can be made of materials such as Hastelloy and titanium alloy according to specific experimental requirements; the balance flow channel 20 is used for conveying balance fluid, wherein the balance fluid can be at least one of gas or liquid, such as inert gas such as nitrogen and argon.

[0059] It can be understood that the first layer plate 1 and the second layer plate 2 can also be replaced by other shapes from the same shape of the layer plate to adapt to specific installation and use conditions.

[0060] The sealing member 3 is arranged between the first layer plate 1 and the second layer plate 2.

[0061] The sealing member 3 is used to seal the first layer plate 1 and the second layer plate 2, and the sealing member 3 can be a sealing ring and can be tightly fixed on the first layer plate 1 or the second layer plate 2 through screws or buckles and the like, and the first layer plate 1 and the second layer plate 2 can be provided with a sealing ring groove matched with the sealing ring.

[0062] The movable member 4 is connected with the sealing member 3 and moves between the first position and the second position.

[0063] The movable member 4 is used to dynamically connect and disconnect the inflow channel 11 and the outflow channel 12. The movable member 4 can be an elastic film layer such as a pressure regulating film which can move and deform to the side with lower pressure according to the pressure change on both sides. The movable member 4 can be connected with the sealing member 3 by sealing fitting or bonding.

[0064] The first layer plate 1 and the second layer plate 2 form a chamber with the sealing member 3, and the movable member 4 divides the chamber into a fluid space 13 and a pressure control space 21. The fluid space 13 connects the inflow channel 11 and the outflow channel 12, and the pressure control space 21 connects the balance flow channel 20. In the first position, the movable member 4 divides the inflow channel 11 and the outflow channel 12 by contacting the first layer plate 1 and closing the inflow channel 11 or the outflow channel 12. In the second position, the movable member 4 is separated from the first layer plate 1, and the inflow channel 11 and the outflow channel 12 are connected through the fluid space 13. The above-mentioned division means that the fluid cannot flow between the two channels or spaces. It can be understood that the contact between the movable member 4 and the first layer plate 1 or the second layer plate 2 can be direct contact or indirect contact through a connecting component.

[0065] In order to prevent solid powder such as catalyst from blocking the fluid channel, the high-throughput pressure controller further comprises a filter device 6 (only the filter device 6 arranged in the inflow channel 11 is shown in the embodiment) arranged in the reaction fluid channel. The filter device 6 can filter out the solid powder in the reaction fluid to keep the channel unblocked.

[0066] When the high-throughput pressure controller works, the balance fluid enters the pressure control space 21 from the balance flow channel 20, and the reaction fluid flows into the fluid space 13 from the inflow channel 11. When the pressure of the pressure control space 21 is higher than that of the fluid space 13, the movable member 4 moves to the first position, the movable member 4 contacts the first layer plate 1 and divides the inflow channel 11 and the outflow channel 12, achieving the effect of closing the fluid channel. When the pressure of the pressure control space 21 is not higher than that of the fluid space 13, the movable member 4 moves to the second position, the movable member 4 is separated from the first layer plate 1, and the inflow channel 11 and the outflow channel 12 are connected through the fluid space 13, thereby achieving the effect of opening the fluid channel.

[0067] Referring to Figure 2 the drawings, Figure 2As shown in the schematic diagram of the gap between the first layer plate and the movable member in Example 1, when the gap between the movable member 4 and the first layer plate 1 is small, the movable member 4 will be sealed with the first layer plate 1 due to the thickness of the movable member 4 itself under the extrusion of external force, so that the inflow channel 11 and the outflow channel 12 are always in a closed state. In order to avoid the above-mentioned early and unnecessary closure of the movable member 4 and the first layer plate 1 under the extrusion of the layer plate by external force, the surface of the first layer plate 1 close to the second layer plate 2 includes a first area 14 and a second area 15, the first area 14 is recessed in the second area 15 and has a height difference with the second area 15, the movable member 4 is arranged towards the first area 14, and the height difference between the first area 14 and the second area 15 appropriately increases the gap between the movable member 4 and the first layer plate 1, which makes the movable member 4 not in contact with the first layer plate 1 under the extrusion of the layer plate by external force, thereby avoiding the above-mentioned early and unnecessary closure. Of course, it can be understood that the gap formed by the height difference between the first area 14 and the second area 15 should not be too large, otherwise, the movable member 4 cannot effectively contact and seal with the first layer plate 1 within a certain range of balanced fluid pressure, which will ultimately affect the pressure control effect.

[0068] Example 2: refer to Figure 3 as shown, Figure 3 the schematic diagram of the high-throughput pressure controller of Example 2.

[0069] In order to facilitate the introduction or outflow of the reaction fluid, the high-throughput pressure controller in Example 1 can further include a third layer plate 7 and a joint 8 arranged on the third layer plate 7, the third layer plate 7 is provided with a first channel and a second channel, an inlet of the first channel is provided with a joint 8, and an outlet of the first channel is connected with an inlet of the inflow channel 11. The inlet of the second channel is connected with the outflow channel 12, and the outlet of the second channel is provided with another joint 8. The connection between the layer plates can be sealed by the sealant 3. In use, the third layer plate 7 is connected and fixed with the system pipeline, the reaction fluid is introduced into the inflow channel 11 through the joint 8 at the inlet of the first channel, and the reaction fluid is introduced out of the outflow channel 12 through the other joint 8 at the outlet of the second channel, and the arrangement of the third layer plate 7 will make the replacement of other layer plates and their accessories more convenient.

[0070] Example 3: refer to Figure 4 as shown, Figure 4 the schematic diagram of the high-throughput pressure controller of Example 3.

[0071] The high-throughput pressure controller of the present embodiment comprises a plurality of the high-throughput pressure controllers of Embodiment 1 arranged in parallel, i.e. the inflow channel, the outflow channel, the balance flow channel, the chamber and the movable member form a pressure control unit, at least two pressure control units are arranged between the first layer plate and the second layer plate, the first layer plate 1 and the second layer plate 2 are provided with a common channel 22 in addition to the plurality of pressure control units, the common channel 22 comprises an inlet arranged on the first layer plate 1 or the second layer plate 2; the second layer plate 2 comprises a balance flow channel 20 corresponding in number to the number of the high-throughput pressure controllers arranged in parallel, and the balance flow channel 20 is at least two, each balance flow channel 20 is connected to the common channel 22 in parallel.

[0072] The term "at least two" can be understood as two, three, four and more, that is, the number of pressure control units can be two, three, four and more. Figure 4 The case where the pressure control units are four is shown only by way of example.

[0073] As shown in Figure 4 the common channel 22 can reach the second layer plate 2 from the first layer plate 1 through the gap between the upper and lower plate layers, and be distributed to the corresponding balance flow channels 20 in four ways. It should be noted that in some embodiments, each high-throughput pressure controller arranged in parallel can also be provided with a balance fluid channel for each balance flow channel 20, and the balance fluid channel can be connected to a respective separate balance fluid source 51, and the plurality of balance fluid sources 51 provide balance fluid for the plurality of balance flow channels 20 one by one.

[0074] In actual operation of the high-throughput pressure controller of the present embodiment, when the common channel 22 is not connected to the balance fluid, the reaction fluid enters through the inflow channel 11 and flows out from the outflow channel 12 through the fluid space 13, at this time the fluid channel pressure is 0 bar; when the common channel 22 is connected to the balance fluid and maintains a certain pressure, the high-throughput pressure controller of the present embodiment can be used to regulate the fluid pressure of the plurality of fluid channels. Specifically, taking the case where the pressure control unit is provided with four as an example. After the reaction fluid enters through the inflow channel 11, a system pressure of not less than a certain value such as 0.5 bar is generated, and due to the existence of certain differences in the uniformity of physical extrusion of the movable member 4, the pressure of each fluid channel after regulation by the high-throughput pressure controller also has certain fluctuations. For example, Figure 5 is a graph of the fluctuation of the pressure of the four reaction fluid channels with time when the balance fluid pressure in the pressure control space 21 of Embodiment 3 is 11.0 bar, i.e. when the balance fluid pressure in the pressure control space 21 is 11.0 bar, the pressure of the four reaction fluid channels controlled by the high-throughput pressure controller is 10.9 bar, 11.0 bar, 11.0 bar and 11.0 bar respectively, and can be stable for a long time; Figure 6For the pressure fluctuation graph of the 4-way reaction fluid channel with the balanced fluid pressure of 46.2 bar in Example 3, that is, when the balanced fluid pressure of the pressure control space 21 is 46.2 bar, the pressures of the 4 reaction fluid channels are controlled by the high-throughput pressure controller to be 46.3 bar, 46.3 bar, 46.2 bar, and 46.2 bar, respectively. It can be seen that the high-throughput pressure controller provides the balanced fluid for the balanced flow channels 20 of the multiple pressure control units through the common channel 22 at the same time, so that the balanced fluid pressures of the pressure control units are almost the same, that is, the pressure error of each pressure control space 21 is greatly reduced, and the pressure control effect of the parallel reaction is greatly improved. The high-throughput pressure controller of the present application can control the opening and closing of multiple fluid channels at the same time through the movable member 4, and then regulate the system pressure, without the need to set a back pressure valve at the outlet of each reactor, which greatly reduces the equipment cost.

[0075] Example 4: refer to Figure 7 as shown, Figure 7 The high-throughput pressure controller and the balanced fluid control system of Example 4 are shown in the schematic diagram.

[0076] In order to facilitate the control of the balanced fluid pressure, the high-throughput pressure controller of the present embodiment further comprises a balanced fluid control system 5 on the basis of Examples 1-3, and the balanced fluid control system 5 comprises: a balanced fluid source 51 and a first pressure controller 52. The balanced fluid source 51 is used to provide fluid for the balanced flow channel 20; the first pressure controller 52 is connected between the balanced fluid source 51 and the balanced flow channel 20, and the first pressure controller 52 can be a pressure reducing valve, and the outlet thereof is connected with the balanced flow channel 20 or the common channel 22. In this way, the balanced fluid source 51 provides balanced fluid for the balanced flow channel 20, and the first pressure controller 52 can control the pressure of the balanced fluid.

[0077] The balanced fluid control system 5 can further comprise: a first fluid controller 53 and a balanced fluid drainage channel 54. The inlet of the first fluid controller 53 is connected between the balanced flow channel 20 and the outlet of the first pressure controller 52. The first fluid controller 53 can be a mass flow controller or a needle valve. The balanced fluid drainage channel 54 is connected with the outlet of the first fluid controller 53. The balanced fluid drainage channel 54 is used to drain the balanced fluid to the balanced fluid source 51, a collection device, or directly discharge the balanced fluid.

[0078] The high-throughput pressure controller of this embodiment works as follows: the balance fluid control system 5 can control the pressure of the balance fluid entering the high-throughput pressure controller. Specifically, when the pressure of the balance flow channel 20 or the pressure control space 21 is too low, the first fluid controller 53 is closed, and the first pressure controller 52 is adjusted to increase the balance fluid pressure to the desired value; when the pressure of the balance flow channel 20 or the pressure control space 21 is too high, the first fluid controller 53 is opened to discharge part of the balance fluid in the balance flow channel 20, and then the first pressure controller 52 is adjusted to decrease to the desired value. It can be seen that the high-throughput pressure controller of this embodiment can efficiently adjust the balance fluid pressure through the balance fluid control system 5, and is convenient to use.

[0079] Embodiment 5: refer to Figure 8 as shown, Figure 8 a schematic diagram of the high-throughput pressure controller and the balance fluid control system of Embodiment 5.

[0080] The balance fluid control system 5 includes a balance fluid source 51, a second fluid controller 53a connected to the outlet of the balance fluid source 51, an outlet of the second fluid controller 53a connected to the pressure control space 21, and a second pressure controller 55 connected to the outlet of the second fluid controller 53a, the inlet of the first fluid controller 53, and the balance flow channel 20. The second pressure controller 55 can be a back pressure valve. In this way, the balance fluid control system 5 regulates the balance fluid pressure entering the high-throughput pressure controller as follows: when the pressure of the balance flow channel 20 is too low, the first fluid controller 53 is closed, the second fluid controller 53a is opened, and the second pressure controller 55 is adjusted to increase the balance fluid pressure to the desired pressure; when the pressure of the balance flow channel 20 is too high, the second fluid controller 53a is closed, the first fluid controller 53 is opened to discharge part of the balance fluid, and then the second pressure controller 55 is adjusted to the desired pressure value. It can be seen that the balance fluid control system 5 in this embodiment can adjust the balance fluid pressure through the first fluid controller 53 and the pressure controller, which is more convenient and accurate.

[0081] Embodiment 6: refer to Figure 9 as shown, Figure 9 a schematic diagram of the high-throughput pressure controller and the balance fluid automatic control system of Embodiment 6.

[0082] The high-throughput pressure controller of the embodiment further comprises a balanced fluid automatic control system 5a capable of automatically controlling the balanced fluid, and comprises a balanced fluid source 51, a first automatic pressure regulating valve 56, a second automatic pressure regulating valve 57, a pressure sensor 58 and a pressure control device 59. The balanced fluid source 51 is used to provide fluid for the balanced flow channel 20; the first automatic pressure regulating valve 56 is connected between the balanced fluid source 51 and the balanced flow channel 20; the inlet of the second automatic pressure regulating valve 57 is connected with the outlet of the first automatic pressure regulating valve 56 and the balanced flow channel 20; the pressure sensor 58 is used to detect the pressure value of the outlet of the first automatic pressure regulating valve 56 and the balanced flow channel 20, and provide the measured data signal to the pressure control device 59 through the link; the pressure control device 59 is used to receive the pressure value of the pressure sensor 58, and send a control signal to the first automatic pressure regulating valve 56 and the second automatic pressure regulating valve 57 through the link.

[0083] In the working process of the high-throughput pressure controller of the embodiment, a desired pressure P1 is set to the pressure control device 59, and the pressure P2 of the balanced flow channel 20 monitored by the pressure sensor 58. If P1 < P2, the pressure control device 59 sends an instruction signal to the automatic pressure regulating valve through the link, and adjusts the pressure P1 and P2 to be consistent through the automatic pressure regulating valve; if P1 > P2, the pressure control device 59 sends an instruction signal to the automatic pressure regulating valve through the link, and adjusts the pressure P1 and P2 to be consistent through the automatic pressure regulating valve. It can be seen that the high-throughput pressure controller of the embodiment can automatically adjust the pressure of the balanced flow channel 20 to the preset value, and is easy to use.

[0084] In the above embodiments, a balanced fluid collecting device (not shown in the figure) can be further provided, which collects used balanced fluid from one, multiple or all pressure controllers, or combines the balanced fluid with the reaction product to quickly take away the reaction product into an analysis system for analysis.
