Description

Technical Field

[0001] This utility model belongs to the field of chemical production, and specifically relates to a reinforcing component for continuous mixing production of pressurized liquid microstructures. Background Technology

[0002] Ordinary droplets and bubbles range in size from a few millimeters to a few centimeters, while microdroplets and microbubbles can reach sizes of micrometers and below. At this scale, microdroplets and microbubbles exhibit physicochemical properties that are drastically different from those in the macroscopic world. The combined effect of surface tension and shear force allows microdroplets to form and maintain a stable morphology within tiny channels. Microdroplets and microbubbles significantly increase the rates of major chemical reactions compared to the bulk phase, and reducing the diameter of microdroplets can significantly improve the reaction rate. Microdroplet and microbubble production technologies are widely used in fields such as chemistry and life sciences, especially in scenarios requiring efficient mass transfer and precise control of reaction conditions.

[0003] Smaller particle sizes in foam extinguishing agents allow for faster coverage of the fire source, improving extinguishing efficiency. Simultaneously, the pressurized liquid microstructure better resists interference from external factors such as wind, maintaining foam stability and durability. Therefore, developing a reinforced component capable of continuously mixing and producing pressurized liquid microstructures is of great significance for enhancing fire extinguishing effectiveness.

[0004] The current shortcomings in the production technology of microdroplets and microbubbles mainly lie in the uniformity, monodispersity, and cost of the droplets. For example, high-speed stirring methods produce larger droplets, and while registration and assembly technologies offer strong control, they struggle to achieve extremely high uniformity. Existing production methods, especially in large-scale production, still face challenges in achieving high dispersibility, as fluctuations in droplet size can affect the quality and performance of the final product. Furthermore, the currently most effective processes and equipment for producing microdroplets and microbubbles also face excessively high costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the main purpose of this utility model is to propose a method for continuously mixing and producing pressurized liquid microstructure reinforcement components, which produces pressurized liquid with small particle size and stable structure.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A reinforcing component for continuously mixing pressurized liquid microstructures includes a mixer body with a mixing chamber inside. The lower end of the mixer body has a gas inlet channel extending to the mixing chamber, the left end has a liquid inlet channel extending to the mixing chamber, and the right end has an outlet channel extending to the mixing chamber.

[0008] Furthermore, in the aforementioned reinforced component for continuous mixing and production of pressurized liquid microstructures, the upper end of the mixer body is also provided with a pressure gauge connection interface extending to the mixing chamber, and a digital display pressure gauge is connected to the pressure gauge connection interface.

[0009] Furthermore, in the aforementioned reinforced component for continuous mixing and production of pressurized liquid microstructures, the outlet channel located within the mixer body is also connected to a mixing chamber outlet connector, which is fixedly connected to the outer surface of the annular mixing channel; the outlet channel is connected to an external pipeline.

[0010] Furthermore, in the aforementioned reinforced component for continuous mixing production of pressurized liquid microstructures, the gas inlet channel, liquid inlet channel, and outlet channel are all connected to the mixing chamber via pipelines.

[0011] Furthermore, in the aforementioned reinforced component for continuous mixing and production of pressurized liquid microstructures, the diameter of the gas inlet channel, liquid inlet channel, outlet channel, and pressure gauge connection interface is 1.5 mm.

[0012] Furthermore, in the aforementioned method of continuously mixing and producing a reinforcing component for pressurized liquid microstructures, the diameter of the mixing chamber is 3 mm.

[0013] Furthermore, in the aforementioned reinforced component for continuous mixing production of pressurized liquid microstructures, the diameter of the mixing chamber outlet connector is 0.8 mm.

[0015] Furthermore, in the aforementioned reinforced component for continuous mixing production of pressurized liquid microstructures, the pressure gauge connection interface, gas inlet channel, liquid inlet channel, outlet channel, and mixer body are made of stainless steel.

[0016] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0017] 1. The present invention provides a technical solution in which compressed gas generated by an air compressor and a foam solution of the liquid to be treated enter the mixing chamber through the gas phase inlet and the liquid phase inlet, respectively. The liquid forms a circular jet or liquid film jet within the mixing chamber. Due to the small inlet diameter, the gas velocity entering the mixing chamber is high, and the resulting strong shear force tears the liquid film and liquid column into fine droplets. Furthermore, after entering the mixing chamber, the gas dissolves into the liquid, forming bubbles inside the liquid, which flow in a bubble-like manner within the mixing chamber. During the two-phase flow, the bubbles accelerate, deform, and expand, compressing the liquid into filaments at the mixing chamber outlet. Due to the reduced outlet diameter, the velocity of the ejected gas-liquid mixture increases sharply. Within a very short distance from the mixing chamber outlet, the sudden increase in pressure difference between the inside and outside of the bubbles causes rapid expansion, leading to secondary rupture and further reducing the bubble size.

[0018] 2. The present invention provides a technical solution in which the mixing chamber outlet channel and the mixing head body form an annular channel as a gas inlet, thereby avoiding the blockage of the gas inlet channel due to displacement of the mixing chamber outlet channel.

[0019] 3. The technical solution provided by this utility model has a simple structure, is easy to process, has low cost, is highly practical, the mixing chamber outlet channel is replaceable, and it is made of stainless steel. It can be used under working conditions of pressure 20MPa and temperature 500℃, and has a wider range of applicable conditions.

[0020] 4. The pressurized liquid generated by the technical solution provided by this utility model has a nanoscale gas-liquid interface, thick foam walls and stable structure, and has a good gas-liquid strengthening effect, which greatly increases the contact area between gas and liquid and improves the mass transfer and heat transfer performance of the reaction.

[0027] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0029] Example 1

[0030] A reinforcing component for continuous mixing production of pressurized liquid microstructures, see reference. Figure 1-3 The mixer includes a mixer body 1. The upper end of the mixer body 1 has a pressure gauge connection interface 6 extending to the mixing chamber 7 of the mixer body 1, used to detect the pressure in the mixing chamber 7. The lower end has a gas inlet channel 5 extending to the mixing chamber 7 of the mixer body 1, and the left end has a liquid inlet channel 4 extending to the mixing chamber 7 of the mixer body 1. Gas enters the mixing chamber 7 of the mixer body 1 through the gas inlet channel 5, and liquid enters the mixing chamber 7 of the mixer body 1 through the liquid inlet channel 4, where gas and liquid are mixed. The right end has an outlet channel 3 extending to the mixing chamber 7 of the mixer body 1, facilitating the ejection of the gas-liquid mixture.

[0031] The outlet channel 3 is located inside the mixer body 1 and is connected to a mixing chamber outlet connector 2. The mixing chamber outlet connector 2 is fixedly connected to the outer surface of the annular mixing channel 8. The outlet channel 3 is connected to an external pipeline.

[0032] The mixing chamber outlet connector 2 forms an annular channel with the mixing head body, serving as a gas inlet and preventing the gas inlet channel from being blocked due to the rotational displacement of the pad.

[0033] More specifically, the pressure gauge connection interface 6 is connected to a digital display pressure gauge 9, a gas inlet channel 5, a liquid inlet channel 4, and an outlet channel 3, all of which are connected to the mixing chamber 7 through pipelines.

[0034] Furthermore, the diameter of the gas inlet channel, liquid inlet channel, outlet channel, and pressure gauge connection interface is 1.5mm; the diameter of the mixing chamber 7 is 3mm; and the diameter of the mixing chamber outlet connector is 0.8mm.

[0035] The mixing chamber outlet connector is made of PEI resin; the pressure gauge connection interface, gas inlet channel, liquid inlet channel, outlet channel and mixer body are made of 316 stainless steel, which is beneficial for operation under high temperature and high pressure conditions.

[0036] An annular mixing channel 8 is also provided on the pipeline between the outlet channel 3 and the mixing chamber 7. The annular mixing channel 8 is connected to the gas inlet channel 5, and the outlet of the annular mixing channel 8 is connected to the mixing chamber 7. The liquid forms a circular jet or liquid film jet in the mixing chamber. Due to the small inlet diameter, the gas enters the mixing chamber at a high velocity, and the strong shear force generated will tear the liquid film and liquid column into fine droplets.

[0037] In practical use: the liquid storage tank 10 is connected to the plunger pump 11 via a pipeline, and the plunger pump 11 is connected to the gas-liquid mixer 1 via a pipeline; the gas-liquid mixer 1 is connected to the booster pump 12 via a pipeline, and the booster pump 12 is connected to the water and oil removal tank 13 via a pipeline; the water and oil removal tank 13 is connected to the air compressor 14 via a pipeline. The compressed gas generated by the air compressor and the solution to be treated enter the mixing chamber of the mixer body 1 from the gas inlet channel 5 and the liquid inlet channel 4, respectively. The liquid forms a circular jet or liquid film jet in the mixing chamber. Due to the small inlet diameter, the gas velocity entering the mixing chamber is high, and the strong shear force generated will tear the liquid film and liquid column into fine droplets. Furthermore, after the gas enters the mixing chamber of the mixer body 1, it dissolves into the liquid, forming bubbles inside the liquid, and flows in a bubble-like manner in the mixing chamber. During the two-phase flow, the bubbles accelerate, deform, and expand, squeezing the liquid into filaments at the outlet of the mixing chamber. As the outlet diameter decreases, the velocity of the gas-liquid mixture ejected increases sharply. Within a very short distance from the outlet channel 3 of the mixing chamber 7 away from the mixer body 1, the pressure difference between the inside and outside of the bubbles suddenly increases and they expand rapidly, leading to secondary rupture and further reduction in bubble size.

[0038] Application examples

[0039] This embodiment provides a continuous mixing method for producing pressurized air foam microstructures, which specifically includes the following steps:

[0040] Step 1: Turn on the air compressor 14. When the pressure inside the booster pump 12 reaches 2-3 MPa, open the outlet valve of the booster pump 12. During this process, the pressure at the outlet of the air compressor 14 should be kept stable at 0.4-0.8 MPa.

[0041] Step 2: Adjust the pressure reducing valve of air compressor 14 to adjust the pressure to the pressure resistance range of the gas flow meter (0.5 MPa), and control the gas flow rate to 0.4 m³ / s. 3 / h;

[0042] Step 3: Continuously supply compressed air to the mixing chamber 7 of the continuous mixing production of the pressurized liquid microstructure reinforcement component provided in Example 1. The compressed air has a water content of ≤50 ppm after being treated by the dewatering and deoiling tank 13.

[0043] Step 4: Mix Class A fire extinguisher foam concentrate with water at a mass ratio of 3:97 to obtain a foam solution with a foam concentrate mass fraction of 3%, and store it in liquid storage tank 10;

[0044] Step 5: Set the liquid flow rate and start the plunger pump 11 to deliver a foam solution with a mass fraction of 3% at a flow rate of 20 ml / min.

[0045] Step 6: Under the condition of maintaining a gas-liquid volume ratio of 1:50-1:150, the pressure in the mixing chamber 7 is monitored in real time through the digital pressure gauge 9 connected to the upper interface of the gas-liquid mixer 1. When the pressure in the mixing chamber 7 reaches 0.25 MPa, compressed air foam with uniform particle size can be generated. The minimum particle size can reach 600±50 nm, and the average particle size can reach 10.1±0.5 μm. The foam particle size is uniform.
