Description

Technical Field

[0001] This invention relates to the field of microchannel technology, and more particularly to a microchannel washing device. Background Technology

[0002] In the production and processing of energetic materials, washing (or quenching) is a crucial purification process. Its core requirement is to achieve efficient purification of materials while minimizing safety risks. Existing washing methods for energetic materials are mainly divided into two categories: batch and continuous. Batch washing primarily uses a kettle-type washing system, while continuous washing primarily uses a tower-type washing system. However, both of these washing methods have the following typical drawbacks when used:

[0003] 1. The typical drawbacks of the batch washing method are: it can only be operated intermittently, the online liquid holding capacity is large (usually in the m³ range), and it needs to be equipped with a stirring device. The mechanical friction and local overheating generated during the stirring process can easily cause thermal runaway or explosion of energetic materials. At the same time, the mixing is uneven, there are dead zones, the washing efficiency is low, the solvent consumption is large, and the purity fluctuates greatly between batches, which cannot meet the needs of continuous and safe production of energetic materials.

[0004] 2. The typical drawbacks of tower washing are: although it is a continuous operation, the liquid holding capacity is still relatively large, which poses the risk of flooding and material leakage; and it requires an external pump to transport energetic materials. The mechanical actions of the pump head, such as shearing, squeezing, and seal wear, are major safety hazards for sensitive energetic materials and can easily lead to safety accidents; at the same time, there is channeling in the tower, resulting in low mass transfer efficiency, incomplete washing, and the equipment is large in size and difficult to maintain.

[0005] Existing technologies include microchannel washing techniques for energetic materials. While these microchannel washing techniques offer advantages such as low liquid holdup (mL to L level) and high mass transfer efficiency, they still suffer from the following drawbacks:

[0006] 1. As is well known, the washing process includes two necessary steps: first, a washing step of mixing two phase materials for washing one of the target materials; and second, a separation step of separating the two phase materials again. However, the microchannel washing technology in the prior art is only suitable for the washing step and does not have the function of separating the two phases. Therefore, the two phase materials after microchannel washing still need to be introduced into a device specifically for two-phase separation (e.g., a kettle). This not only makes the washing and purification process complicated, but may also cause the entire washing and purification process to be intermittent due to the need to introduce external equipment such as a kettle.

[0007] 2. When using microchannels to wash energetic materials, the energetic materials still require a pump head to provide power for transport. Therefore, there is still a safety hazard, such as an explosion, that may occur due to the mechanical actions of the pump head, such as shearing, squeezing, and seal wear. In addition, the microchannel washing technology provided in the current technology is difficult to fully mix the two phases of materials, and the washing effect needs to be improved. Summary of the Invention

[0008] To address the aforementioned technical problems in the prior art, embodiments of the present invention provide a microchannel washing device.

[0009] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of the present invention is as follows:

[0010] A microchannel washing device includes a washing module, wherein the washing module is configured with a washing microchannel having a washing inlet and a washing outlet. Heavy phase energetic material and light phase washing liquid enter the washing microchannel through the washing inlet and flow out through the washing outlet. The microchannel washing device further includes a separation module; wherein:

[0011] The separation module is configured with a separation microchannel having a mixture inlet, a heavy phase outlet, and a light phase outlet. The separation module is arranged so that the separation microchannel is vertical. The mixture of the heavy phase energetic material and the light phase washing liquid enters the separation microchannel through the mixture inlet.

[0012] The separation microchannel includes a main separation zone, a mixture inlet channel is constructed between the mixture inlet and the middle of the main separation zone, a heavy phase outlet channel is constructed between the heavy phase outlet and the bottom of the main separation zone, and a light phase outlet channel is constructed between the light phase outlet and the upper part of the main separation zone.

[0013] A heavy phase temporary storage area is configured between the heavy phase outlet channel and the heavy phase outlet, arranged in parallel with the main separation zone. The bottom of the heavy phase outlet is connected to the heavy phase temporary storage area, and the connection node between the heavy phase outlet channel and the heavy phase temporary storage area is higher than the connection node between the light phase outlet channel and the main separation zone.

[0014] Preferably, the separation module is provided with an air vent near its upper side, allowing communication with the outside atmosphere, and the air vent is at least higher than the top of the heavy phase temporary storage area; wherein:

[0015] A balanced air passage is constructed between the top of the heavy phase storage area and the air pore.

[0016] Preferably, the separation microchannel further includes a gas collection area, which is located near and extends along the upper side of the separation module, and the vent is disposed at the proximal end of the gas collection area.

[0017] Preferably, the separation microchannel further includes a mixture storage area, which is located between the mixture inlet channel and the main separation zone. The mixture inlet channel communicates with the top of the mixture storage area, and the bottom of the mixture storage area communicates with the main separation zone; wherein:

[0018] The top of the mixture storage area is connected to the far end of the gas collection area.

[0019] Preferably, the separation microchannel further includes a gas guiding zone, which is located between the top of the mixture storage zone and the far end of the gas collection zone, and is situated above the main separation zone.

[0020] Preferably, the separation microchannel further includes a light phase guiding region, which is located between the light phase outlet channel and the main separation region; wherein:

[0021] The light phase guiding zone extends upward and communicates with the far end of the gas collection zone.

[0022] Preferably, the washing inlet includes a light phase inlet and a heavy phase inlet, a venturi channel is led out from the light phase inlet, and a drainage channel is led out from the heavy phase inlet. The drainage channel extends to the venturi channel, at least allowing the washing liquid to enter the venturi channel from the light phase inlet, and introducing energetic material from the heavy phase inlet into the venturi channel and ejecting it from the nozzle at the distal end of the venturi channel as it flows through the venturi channel.

[0023] Preferably, the gas-liquid mixture of washing liquid and inert gas enters the Venturi channel through the light phase inlet.

[0024] Preferably, the washing microchannel is a linearly extending channel to allow fluid to flow along the extension direction of the washing microchannel; wherein:

[0025] The washing microchannel includes multiple mixing chambers connected in series, and the mixing chambers are configured with mixing structures for changing the direction of the fluid and / or for mixing the fluids after separation.

[0026] Preferably, the washing module and the separation module are stacked.

[0027] Compared with the prior art, the beneficial effects of the microchannel washing device disclosed in this invention are:

[0028] 1. The microchannels in the separation module enable the separation of energetic materials and washing liquid in the mixture, thereby replacing the batch container for separating two-phase materials.

[0029] 2. By utilizing the separation zone with a large area and volume configured in the microchannel as the site for separating two-phase materials, the uninterrupted continuous separation of two-phase materials can be achieved. In combination with the washing microchannel, continuous quenching and separation of energetic materials can be realized.

[0030] 3. By making the connecting node C, which leads to the heavy phase storage region, lower than the connecting node D, which is used to derive the light phase material, it is possible to avoid the unwanted consequence of energetic material flowing out of the connecting node D.

[0031] 4. By configuring an ejector structure with a Venturi channel and a drainage channel in the junction area between the light phase inlet and the heavy phase inlet (i.e., the inlet area of ​​the washing microchannel), the energetic material can be actively attracted into the washing microchannel by utilizing the Venturi effect. In this way, it is not necessary to use a pump head to provide power to supply the energetic material into the washing microchannel. Therefore, it is possible to avoid safety accidents such as explosions caused by shearing, squeezing, and friction of the energetic material by using a pump head.

[0032] 5. Because the washing liquid and energetic materials are atomized to a large extent during the spraying process from the nozzle of the Venturi channel, the washing liquid and energetic materials can be fully mixed, thereby significantly improving the quenching effect of the washing liquid on the energetic materials.

[0033] 6. In the area where the light phase inlet and the heavy phase inlet meet, energetic materials are introduced into the washing microchannel by active attraction and flow along the washing microchannel, thereby avoiding back mixing.

[0034] 7. By utilizing the Venturi channel, the energetic material and the washing liquid are fully mixed through atomization, which significantly improves the utilization rate of the washing liquid, reduces the consumption of the washing liquid, and improves the quenching effect.

[0035] 8. Using microchannels to quench energetic materials, continuous quenching operations can be achieved because the material can "enter and exit simultaneously". Furthermore, the plate-shaped washing module occupies less space and can be stacked to obtain more layers of washing microchannels, thereby achieving higher washing efficiency in a limited space.

[0045] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0046] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses a microchannel washing device, which includes a washing module 200 and a separation module 100. The washing module 200 is used to quench energetic materials, that is, in the washing module 200, the energetic materials, which are heavy phase materials, are quenched using a washing liquid, which is a light phase material. The separation module 100 is used to separate the two phase materials in the mixture, that is, in the separation module 100, the energetic materials in the mixture formed after washing are separated from the washing liquid.

[0047] like Figure 1 As shown, the washing module 200 is configured as a plate-like structure. Microchannels located on the same plane (or the same layer) are configured in the washing module 200. Since this microchannel serves as the quenching site, it can be referred to as the washing microchannel 20. The washing microchannel 20 has a washing inlet and a washing outlet 22. The washing inlet includes a heavy phase inlet 211 and a light phase inlet 212. The washing liquid, which is the light phase material, is mixed with an inert gas (the inert gas is insoluble and does not react with the washing liquid or the energetic material) in a certain proportion and then enters the washing microchannel 20 through the light phase inlet 212. The energetic material, which is the heavy phase material, enters the washing microchannel 20 through the heavy phase inlet 211. The energetic material and the washing liquid are initially mixed in the upstream section of the washing microchannel 20 and flow along the washing microchannel 20. During the flow, they continue to mix, thereby achieving the quenching of the energetic material by the washing liquid. The mixture of the quenched energetic material, the washing liquid with adsorbed impurities, and the inert gas flows out from the washing outlet 22.

[0048] In this invention, an ejector structure is configured at the junction of the light phase inlet 212 and the heavy phase inlet 211. This ejector structure includes a Venturi channel 2121 and a drainage channel 2111. The Venturi channel 2121 extends from the light phase inlet 212 and forms a jet nozzle at its distal end. The drainage channel 2111 extends from the heavy phase inlet 211 and extends through the contraction section of the Venturi channel 2121. Based on the Venturi effect, the mixture of washing liquid and inert gas from the light phase inlet 212 experiences a significant increase in velocity and a significant decrease in pressure when flowing through the contraction section of the Venturi channel. This creates a pressure drop in the contraction section, automatically attracting energetic materials through the drainage channel 2111 into the contraction section, where they are then ejected from the jet nozzle. During ejection, the fluid undergoes a certain degree of atomization, dispersing the washing liquid, inert gas, and energetic materials. This ensures thorough contact and mixing between the washing liquid and the energetic materials, significantly improving the quenching effect of the washing liquid on the energetic materials.

[0049] In some preferred structures, multiple Venturi channels 2121 are drawn from the light phase inlet 212, and multiple drainage channels 2111 are drawn from the heavy phase inlet 211. Each Venturi channel 2121 is connected to drainage channels 2111 on both sides, which can significantly improve the total mixing rate of energetic materials and washing liquid, and thus significantly improve the quenching efficiency of washing liquid on energetic materials.

[0050] The washing microchannel 20 can be configured as a channel structure with a large flow cross-section and a short extension path (not shown in the attached figure); the washing microchannel 20 can also be configured as follows: Figure 1 The microchannel structure shown has a relatively small flow cross-section but a long extension path, i.e., a channel configured as a long path extending linearly.

[0051] In some preferred structures, a number of mixing chambers 23 are arranged in series in the long-path washing microchannel 20. Interception and flow guiding structures are arranged in the mixing chambers 23, so that when the fluid flows through each mixing chamber 23, the fluid undergoes a separation / reversal / remixing process, thereby further improving the mixing effect of the washing liquid and the energetic material, and thus improving the quenching effect on the energetic material.

[0052] The advantages of the washing module 200 provided by the present invention are as follows:

[0053] 1. By configuring an ejector structure with a Venturi channel 2121 and a drainage channel 2111 in the junction area of ​​the light phase inlet 212 and the heavy phase inlet 211 (i.e., the inlet area of ​​the washing microchannel 20), the energetic material can be actively attracted into the washing microchannel 20 by utilizing the Venturi effect. In this way, it is not necessary to use a pump head to provide power to supply the energetic material into the washing microchannel 20. Therefore, it is possible to avoid safety accidents such as explosions caused by shearing, squeezing, and friction of the energetic material by using a pump head.

[0054] 2. Because the washing liquid and energetic material are atomized to a large extent during the spraying process from the nozzle of the Venturi channel 2121, the washing liquid and energetic material can be fully mixed, thereby significantly improving the quenching effect of the washing liquid on the energetic material.

[0055] 3. In the area where the light phase inlet 212 and the heavy phase inlet 211 meet, energetic materials are introduced into the washing microchannel 20 by active attraction and flow along the washing microchannel 20, thereby avoiding back mixing.

[0056] 4. By utilizing the Venturi channel 2121, the energetic material and the washing liquid are fully mixed through atomization, which significantly improves the utilization rate of the washing liquid, reduces the consumption of the washing liquid, and improves the quenching effect.

[0057] 5. By using microchannels to quench energetic materials, continuous quenching operations can be achieved because the materials can "enter and exit simultaneously". Furthermore, the washing module 200 with its plate-like structure occupies a small space and can be stacked to obtain more layers of washing microchannels 20, thereby achieving higher washing efficiency in a limited space.

[0058] like Figure 2 As shown, the separation module 100 is configured as a plate-like structure. Microchannels located on the same plane (or the same layer) are configured in the separation module 100. Since the microchannels serve as the place for separating the heavy phase and the light phase, the microchannels may be referred to as separation microchannels 10. The separation microchannel 10 has a mixture inlet 11, a heavy phase outlet 121, and a light phase outlet 122. The mixture inlet 11 is directly or through a pipeline connected to the washing outlet 22 of the washing module 200. The mixture of the quenched energetic material (as the heavy phase material), the washing liquid (as the light phase material) that has adsorbed impurities from the energetic material, and the inert gas flows out through the washing outlet 22 and enters the separation microchannel 10 through the mixture inlet 11. During the flow through the separation microchannel 10, the mixture of the energetic material, the washing liquid, and the inert gas is separated by the separation microchannel 10 configured in this invention. Finally, the quenched energetic material, the washing liquid that has adsorbed impurities, and the inert gas are separated, and the energetic material is discharged from the heavy phase outlet 121, the washing liquid is discharged from the light phase outlet 122, and the inert gas is discharged.

[0059] Regarding the flow of fluid, the washing microchannel 20 of the washing module 200 and the separation microchannel 10 of the separation module 100 are connected in series. In terms of spatial arrangement, the washing module 200 and the separation microchannel 10 can be arranged side-by-side or stacked, with stacking being preferred to save space. Furthermore, the separation module 100 must be kept upright during use.

[0060] In this invention, the separation microchannel 10 is configured with a channel structure having a large flow cross-section. Specifically, the channel is obtained by configuring rectangularly arranged columns in a flat cavity.

[0061] In this invention, the separation microchannel 10 is defined by multiple rectangular regions, which specifically include: a mixture storage region 15, a main separation region 13, a heavy phase storage region 14, a gas guiding region 17, a light phase guiding region 18, and a gas collection region 16.

[0062] The area of ​​the main separation zone 13 is larger than that of the other zones, and therefore, the volume of the main separation zone 13 is larger than that of the other zones. The mixture storage zone 15 is located to the left of the main separation zone 13. The lower part of the mixture storage zone 15 is connected to the middle part of the left side wall of the main separation zone 13 to form a connection node A131. A mixture inlet channel 191 is constructed between the mixture inlet 11 and the top of the mixture storage zone 15. The gas collection zone 16 is located near the top side of the separation module 100. The gas collection zone 16 is a strip-shaped area extending along the top side. The gas collection zone 16 has a vent 161 communicating with the atmosphere at the near end of the left side of the separation module 100. The gas guide zone 17 is located between the gas collection zone 16 and the top of the main separation zone 13. The gas guide zone 17 extends laterally and communicates with the top of the mixture storage zone 15 and the far end of the gas collection zone 16 on the right side of the separation module 100. The heavy phase storage zone 14 is located to the left of the mixture storage zone 15. A heavy phase outlet channel 192 is constructed between the middle of the right side of the heavy phase storage zone 14 and the bottom of the main separation zone 13. The node connecting the heavy phase outlet channel 192 to the bottom of the main separation zone 13 may be called the connecting node B132, and the node connecting the heavy phase outlet channel 192 to the middle of the heavy phase storage zone 14 may be called the connecting node C141. At the top of the heavy phase storage zone 14... A balanced airway 194 is constructed between the gas collection area 16 above and the proximal end of the gas collection area 16; the light phase guide area 18 is located to the right of the main separation area 13. The light phase guide area 18 is a vertical strip-shaped area that extends upward and connects to the far right end of the gas collection area 16. The upper part of the right side of the main separation area 13 is connected to the light phase guide area 18 and forms a connecting node D133; a light phase outlet channel 193 is constructed between the lower end of the light phase guide area 18 and the light phase outlet 122.

[0063] In this invention, connected node C141 is made to be lower than connected node D133 but higher than connected node B132.

[0064] The mixture of energetic material, washing liquid, and inert gas from mixture inlet 11 enters mixture storage zone 15 from the top through mixture inlet channel 191. The inert gas in the mixture rises in mixture storage zone 15 and enters gas guide zone 17, then enters gas collection zone 16 from the far end of gas collection zone 16, and finally exits from vent 161 located near the left side of separation module 100 in gas collection zone 16. In the mixture storage chamber, the majority of the gas components in the mixture are separated. Simultaneously, the mixture in the mixture storage zone 15 enters the main separation zone 13 via the connecting node A131. Because the main separation zone 13 has a large area, the mixture entering the main separation zone 13 has sufficient separation time. Under the action of gravity, the washing liquid, which has a lower density and acts as a lighter phase material, moves upward to the upper part of the main separation zone 13, while the energetic material after quenching, which has a higher density and acts as a heavier phase material, moves downward to the lower part of the main separation zone 13. The upper washing liquid flows out from the connecting node D133 and into the light phase guiding zone 18, and finally flows out through the light phase outlet channel 193 and the light phase outlet 122. When the washing liquid flows through the light phase outlet channel 193, if there is residual gas in the washing liquid, the gas will float up and enter the gas collection zone 16 from the top of the light phase outlet channel 193. The lower energetic material flows into the heavy phase outlet channel 192 through the connecting node B132, and then into the heavy phase temporary storage zone 14 through the connecting node C141. If the energetic material... Residual gas exists in the material. This gas flows into the gas collection zone 16 through the balancing gas channel 194 and is finally discharged through the vent 161. Because the balancing gas channel 194 can promptly discharge the gas in the heavy phase storage zone 14, it can balance the pressure in the heavy phase storage zone 14. This allows the energetic material in the main separation zone 13 to smoothly enter the heavy phase storage zone 14 through the heavy phase outlet channel 192. The energetic material entering the heavy phase storage zone 14 flows from the bottom of the heavy phase storage zone 14 to the heavy phase outlet 121 and is finally discharged and collected. In this way, the separation of energetic material, washing liquid, and inert gas is achieved.

[0065] The advantages of the separation module 100 provided by the present invention are as follows:

[0066] 1. The microchannel in the separation module 100 enables the separation of energetic materials and washing liquid in the mixture, thereby replacing the batch container for separating two-phase materials.

[0067] 2. By utilizing the separation zone with a large area and volume configured in the microchannel as the place for separating two-phase materials, the uninterrupted continuous separation of two-phase materials can be achieved. In turn, in conjunction with the washing microchannel 20, the continuous quenching and separation of energetic materials can be realized.

[0068] 3. By making the connecting node C141 entering the heavy phase storage region 14 lower than the connecting node D133 used to derive the light phase material, it is possible to avoid the undesirable consequence of energetic material flowing out from the connecting node D133.
