Background

High throughput parallel reaction systems are widely used in chemical reaction studies where a plurality of reactors, typically flow-through reactors, are placed in parallel. In order to compare and analyze the experimental results performed in different reactors, it is important to precisely control the process conditions such as the temperature, pressure, space velocity, etc. of each reactor.

When a certain compound can be synthesized using a conventional small fixed bed/fluidized bed reactor, a plurality of such small reactors are arranged in parallel for small-scale production. The reaction conditions such as pressure used in these parallel reactors should be the same as the original single reactor, ensuring that the reaction conditions are the same in all reactors is critical for the scale-up of this compound.

The pressure regulation control of conventional reaction systems is achieved by means of back pressure valves arranged at the reactor outlet, one for each reactor channel, which is obviously disadvantageous because back pressure valves are generally costly and take up a lot of space.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The existing high-flux pressure controller needs to be provided with a back pressure valve at the outlet of each reactor, so that the problems of high equipment cost and large occupied space are caused.

To solve the above problems, the following embodiments are provided:

example 1: referring to fig. 1, fig. 1 is a schematic diagram of a high throughput pressure controller of example 1.

The present embodiment provides a high throughput pressure controller comprising: a first layer 1, a second layer 2, a seal 3 and a movable member 4.

The first laminate 1 is provided with an inflow channel 11 and an outflow channel 12.

The first layer plate 1 can be made of stainless steel, and can also be made of hastelloy, titanium alloy and other materials resistant to fluid corrosion according to specific experimental requirements; the inflow channel 11 is used for inputting a reaction fluid, which can be connected to a reaction fluid supply line of a parallel reaction system or a reactor outflow end line; the outflow channel 12 is used for outputting a reaction fluid, which can be connected to a reactor inlet end pipeline or a detection analysis end inlet of a parallel reaction system; the number of layers of the first layer plate 1 can be increased according to the actual flow path requirement of high flux, and the first layer plate is used for simultaneous input of multiple reaction fluids.

The second plate 2 is provided with a balancing flow passage 20.

The second layer plate 2 can be made of stainless steel, or made of hastelloy, titanium alloy and the like which can resist fluid corrosion according to specific experimental requirements; the balancing flow channel 20 is used for conveying a balancing fluid, wherein the balancing fluid may be at least one of a gas or a liquid, for example, inert gas such as nitrogen, argon, etc. is selected as the balancing fluid.

It will be appreciated that the first ply 1 and the second ply 2 may be replaced with other shapes from ply shapes equivalent to suit particular installation and use situations.

A seal 3 is arranged between the first layer plate 1 and the second layer plate 2.

The sealing element 3 is used for sealing the first layer plate 1 and the second layer plate 2, the sealing element 3 can be a sealing ring, and can be tightly fixed on the first layer plate 1 or the second layer plate 2 through connecting elements such as screws or buckles, and sealing ring grooves matched with the sealing ring can be formed in the first layer plate 1 and the second layer plate 2.

A movable member 4 connected to the seal 3 and movable between a first position and a second position.

The movable member 4 is used for dynamically connecting and disconnecting the inflow channel 11 and the outflow channel 12, and the movable member 4 may be an elastic membrane layer such as a pressure adjusting membrane which can move and deform to the smaller pressure side according to the pressure change of the two sides; the movable member 4 may be connected to the seal 3 by sealing engagement or adhesion.

Wherein a chamber is formed between the first laminate 1, the second laminate 2 and the seal 3, the movable member 4 divides the chamber into a fluid space 13 and a pressure control space 21, the fluid space 13 communicates with the inflow passage 11 and the outflow passage 12, and the pressure control space 21 communicates with the balance flow passage 20. In the first position, the movable member 4 separates the inflow channel 11 and the outflow channel 12 by contacting the first deck 1 and closing the inflow channel 11 or the outflow channel 12, etc., in the second position, the movable member 4 is out of contact with the first deck 1, and the inflow channel 11 and the outflow channel 12 communicate through the fluid space 13; the separation means that fluid cannot flow between two channels or spaces. It will be appreciated that the movable member 4 may be in direct contact with the first or second laminate 1, 2 or may be in indirect contact via engagement means.

In order to prevent solid powder such as catalyst from blocking the flow channels, the high-throughput pressure controller further comprises a filter device 6 provided on the reaction flow channels (the embodiment only shows the filter device 6 provided on the inflow channel 11). The filtering device 6 can filter out solid powder in the reaction fluid, and keep the channel clear.

When the high-flux pressure controller in the above technical scheme works, balance fluid enters the pressure control space 21 from the balance runner 20, 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, and the movable member 4 contacts with the first layer plate 1 and separates the inflow channel 11 and the outflow channel 12, so that the effect of closing the fluid channel is realized; when the pressure of the pressure control space 21 is not higher than the pressure of the fluid space 13, the movable member 4 is moved to the second position, the movable member 4 is out of contact with the first laminate 1, and the inflow passage 11 and the outflow passage 12 are communicated through the fluid space 13, thereby achieving the effect of opening the fluid passage.

Referring to fig. 2, fig. 2 is a schematic diagram showing that in embodiment 1, when the gap between the first layer board and the movable member is smaller, the movable member 4 and the first layer board 1 will generate a sealing effect similar to that of the first layer board 1 under the pressing of external force due to a certain thickness of the movable member 4 itself, so that the inflow channel 11 and the outflow channel 12 are always in a closed state, in order to avoid such advanced and unnecessary closing of the movable member 4 and the first layer board 1 when the movable member 4 presses the layer board, the board surface of the first layer board 1 near the second layer board 2 includes a first area 14 and a second area 15, the first area 14 is concavely arranged in the second area 15 and forms 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 properly increases the gap between the movable member 4 and the first layer board 1, so that the movable member 4 will not contact and seal with the first layer board 1 even under the pressing of the layer board, thereby avoiding such advanced and unnecessary closing. Of course, it will be appreciated that the gap formed by the difference in height between the first region 14 and the second region 15 should not be too large, otherwise the balance fluid pressure is within a certain range, the movable member 4 cannot effectively contact and seal with the first layer plate 1, and the pressure regulating effect is ultimately affected.

Example 2: referring to fig. 3, fig. 3 is a schematic diagram of a high throughput pressure controller of example 2.

In order to facilitate the introduction or extraction of the reaction fluid, the high-throughput pressure controller in embodiment 1 may further include a third plate 7 and a connector 8 disposed on the third plate 7, wherein the third plate 7 is provided with a first channel and a second channel, the inlet of the first channel is provided with a connector 8, and the outlet of the first channel is connected with the inlet of the inflow channel 11. The inlet of the second channel and the outflow channel 12, the outlet of the second channel being provided with a further joint 8. The joints between the plies may be sealed by a sealant 3. When the device is used, the third layer plate 7 is fixedly connected 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, the reaction fluid is led out from the outflow channel 12 through the other joint 8 at the outlet of the second channel, and the replacement of other layer plates and accessories thereof is more convenient due to the arrangement of the third layer plate 7.

Example 3: referring to fig. 4, fig. 4 is a schematic diagram of a high throughput pressure controller of example 3.

On the basis of embodiment 1, the high-throughput pressure controller of this embodiment includes a plurality of high-throughput pressure controllers arranged in parallel in embodiment 1, that is, an inflow channel, an outflow channel, a balance channel, a chamber and a movable member form a pressure control unit, at least two pressure control units are disposed between a first layer plate and a second layer plate, the first layer plate 1 and the second layer plate 2 are provided with a plurality of pressure control units, and a common channel 22 is also provided, where the common channel 22 includes an inlet disposed on the first layer plate 1 or the second layer plate 2; the second plate 2 includes at least two balancing flow passages 20 corresponding to the number of high-throughput pressure controllers arranged in parallel, each balancing flow passage 20 being connected in parallel to a common passage 22.

The term "at least two" is to be understood as two, three, four and more, that is to say the number of pressure control units may be two, three, four and more. Fig. 4 shows only an exemplary case where the pressure control units are four.

As shown in fig. 4, the common channel 22 may reach the second deck 2 from the first deck 1 via the upper and lower deck gaps and split into 4 channels for distribution to the corresponding balancing flow channels 20. It should be noted that, in some embodiments, each of the parallel high-throughput pressure controllers may further be provided with a separate balancing fluid channel for each of the balancing flow channels 20, and the balancing fluid channels may be connected to respective separate balancing fluid sources 51, and the balancing fluid sources 51 may provide balancing fluid to the balancing flow channels 20 in a one-to-one correspondence.

When the high-throughput pressure controller of the embodiment is actually operated, the reaction fluid enters through the inflow channel 11 and flows out of the outflow channel 12 through the fluid space 13 under the condition that the balance fluid is not introduced into the common channel 22, and the pressure of the fluid channel is 0bar at this time; when the common channel 22 is filled with balance fluid and has a certain pressure, the high-flux pressure controller of the present embodiment can regulate the fluid pressure of the plurality of fluid channels. Specifically, four pressure control units are provided as an example. After the reaction fluid enters through the inflow channel 11, a system pressure not lower than a certain value such as 0.5bar is generated, and meanwhile, due to a certain difference in uniformity of the physical extrusion movable member 4, a certain fluctuation exists in the pressure of each fluid channel regulated and controlled by the high-flux pressure controller. For example, fig. 5 is a graph showing the fluctuation of the pressure of the 4-way reaction fluid channel with time when the equilibrium fluid pressure is 11.0bar in example 3, that is, when the equilibrium fluid pressure of the pressure control space 21 is 11.0bar, the pressure of the 4-way reaction fluid channel is controlled to be 10.9bar, 11.0bar, respectively, by the high-throughput pressure controller, and can be stabilized for a long period of time; fig. 6 is a graph showing the fluctuation of the pressure of the 4 reaction fluid channels with time at the equilibrium fluid pressure of 46.2bar in example 3, i.e., the pressure of the 4 reaction fluid channels was controlled to be 46.3bar, 46.2bar by the high-throughput pressure controller when the equilibrium fluid pressure of the pressure control space 21 was 46.2bar, respectively. It can be seen that the high-throughput pressure controller provides the balance fluid for the balance runners 20 of the plurality of pressure control units simultaneously through the common channel 22, so that the balance fluid pressure of each pressure control unit is almost uniform, that is, the pressure error of each pressure control space 21 is greatly reduced, and the pressure control effect of parallel reaction is greatly improved. The high-flux pressure controller can control the opening and closing of the multipath fluid channels through the movable component 4 at the same time, so as to regulate and control the system pressure, and a back pressure valve is not required to be arranged at the outlet of each reactor, so that the equipment cost is greatly reduced.

Example 4: referring to fig. 7, fig. 7 is a schematic diagram of the high-throughput pressure controller and balanced fluid control system of example 4.

In order to facilitate controlling the balance fluid pressure, the high-throughput pressure controller of this embodiment further includes a balance fluid control system 5 on the basis of embodiments 1-3, the balance fluid control system 5 including: balance fluid source 51 and first pressure controller 52. A balance fluid source 51 for providing fluid to the balance channel 20; a first pressure controller 52 is connected between the balance fluid source 51 and the balance flow channel 20, and the first pressure controller 52 may be a pressure reducing valve, the outlet of which is connected to the balance flow channel 20 or the common passage 22. As such, the balance fluid source 51 provides balance fluid to the balance channel 20 and the first pressure controller 52 may control the pressure of the balance fluid.

The balance fluid control system 5 may further include: a first fluid controller 53 and a balancing fluid drain channel 54. The inlet of the first fluid controller 53 is connected between the balance flow channel 20 and the outlet of the first pressure controller 52. The first fluid controller 53 may be a mass flow controller or a needle valve. The balance fluid drain channel 54 is connected to the outlet of the first fluid controller 53. Balance fluid drain channel 54 is used to drain balance fluid to balance fluid source 51, a collection device, or to drain balance fluid directly.

In operation of the high-throughput pressure controller of this embodiment, 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 small, close the first fluid controller 53 and adjust the first pressure controller 52 to increase the balance fluid pressure to a desired value; when the pressure in the balance flow path 20 or the pressure control space 21 is larger, the first fluid controller 53 is opened to discharge a part of the balance fluid in the balance flow path 20, and the first pressure controller 52 is adjusted to be reduced to a desired value. It can be seen that the high-throughput pressure controller of the present embodiment can efficiently adjust the balance fluid pressure through the balance fluid control system 5, and is convenient to use.

Example 5: referring to fig. 8, fig. 8 is a schematic diagram of the high-throughput pressure controller and balanced fluid control system of example 5.

The balancing fluid control system 5 comprises a balancing fluid source 51, a second fluid controller 53a connected to an outlet of the balancing fluid source 51, the outlet of the second fluid controller 53a being connected to the pressure control space 21, and a second pressure controller 55, the inlet of the second pressure controller 55 being connected to the outlet of the second fluid controller 53a, the inlet of the first fluid controller 53 and the balancing flow channel 20, the second pressure controller 55 being a back pressure valve. In this manner, the balance fluid control system 5 regulates the balance fluid pressure entering the high-throughput pressure controller 1 as follows, when the balance flow path 20 pressure is smaller, 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 a desired pressure; when the balance flow path 20 is pressurized, the second fluid controller 53a is closed, the first fluid controller 53 is opened to discharge the balance fluid portion, and the second pressure controller 55 is adjusted to a desired pressure value. It can be seen that the balance fluid control system 5 in this embodiment is capable of adjusting the balance fluid pressure by the first fluid controller 53 and the pressure controller together, and the adjustment is more convenient and accurate.

Example 6: referring to fig. 9, fig. 9 is a schematic diagram of the high-throughput pressure controller and balanced fluid automatic control system of example 6.

The high-throughput pressure controller of this embodiment further includes, on the basis of embodiments 1 to 3, a balance fluid automatic control system 5a, the balance fluid automatic control system 5a being capable of achieving automatic control of the balance fluid, and includes: a source of balancing fluid 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. Wherein the balance fluid source 51 is configured to provide fluid to the balance channel 20; the first automatic pressure regulating valve 56 is connected between the balance fluid source 51 and the balance runner 20; the inlet of the second automatic pressure regulating valve 57 is connected to the outlet of the first automatic pressure regulating valve 56 and the balance flow path 20; the pressure sensor 58 is used for detecting the pressure value of the outlet of the first automatic pressure regulating valve 56 and the balance runner 20, and providing measured data signals to the pressure control device 59 through a link; the pressure control device 59 is configured 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 via a link.

In operation of the high-throughput pressure controller of this embodiment, the pressure of the balance flow path 20 monitored by the pressure sensor 58 is set to P2 by inputting a desired pressure to the pressure control device 59. If P1< P2, the pressure control device 59 sends an instruction signal to the automatic pressure regulating valve via a link, and the pressures P1 and P2 are made to coincide by the adjustment of the automatic pressure regulating valve; if P1> P2, the pressure control device 59 sends an instruction signal to the automatic pressure regulating valve via the link, and the pressure P1 and P2 are made to coincide by the adjustment of the automatic pressure regulating valve. It can be seen that the high-throughput pressure controller of the embodiment can realize automatic adjustment of the pressure of the balance flow channel 20 to a preset value, automatic control and convenient use.

In the above embodiments, a balancing fluid collection device (not shown) may also be provided that collects used balancing fluid from one, more or all of the pressure controllers, or joins the balancing fluid with the reaction product, rapidly carrying the reaction product away into the analysis system for analysis.
