Description

Technical Field

[0001] This invention is an ultrasonic spray microdroplet photoreactor. Background Technology

[0002] In the research and application of photochemical reactions, designing efficient and adaptable reactors is an extremely challenging task. The coupling and matching of multiple fields, including the light field, reaction field, and temperature field, is particularly critical. These fields are intertwined and mutually influential, jointly determining the reaction efficiency, product selectivity, and system stability. The design of a novel ultrasonic spray microdroplet photoreactor emerged in response to this complex context. Its unique dispersion characteristics and rich interfacial interactions open new avenues for photochemical reaction research, but also present unprecedented design challenges. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ultrasonic spray microdroplet photoreactor.

[0004] An ultrasonic spray microdroplet photoreactor includes a light source, a reactor, an atomizer, a water chiller, an electrical control box, and an airflow inlet. The light source provides illumination for the reaction; the atomizer atomizes the reactants into tiny droplets; the reactor contains the reactants and maintains the reaction environment; and the airflow inlet, with its appropriate position and flow rate of the reactant gas, can increase the flow velocity of the fluid within the reactor, thereby increasing the circulation distance of the droplets.

[0005] Furthermore, the light source is one of an LED columnar light source or a lamp tube structure light source.

[0006] Furthermore, the light source includes LED beads, a liquid cooling outlet, a liquid cooling inlet, and a power supply port. The liquid cooling inlet is for coolant to enter, the liquid cooling outlet is for coolant to exit, the power supply port is for connection to power supply equipment, and the LED beads are for providing illumination.

[0007] Furthermore, the reactor includes a vessel body and a cooling chamber. The vessel body is provided with a top cover. The vessel body is installed inside the transparent reaction vessel via a flange. The top cover is connected to the vessel body via bolts and a flange to form a sealed reaction space. The reaction space is provided with a sampling port for taking out samples for testing. The cooling chamber is connected to the vessel body and is provided with a coolant inlet and a coolant outlet.

[0008] Furthermore, the reactor includes other areas and a light-transmitting area. The other areas are made of borosilicate glass, while the light-transmitting area is made of quartz glass.

[0009] Furthermore, an O-ring and a silicone gasket are provided at the connection between the flange and the top cover for sealing.

[0010] Furthermore, the atomizer is an ultrasonic atomizer.

[0011] Furthermore, the atomizer is equipped with a gas inlet and outlet and a spacer made of PTFE material.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] The light source employs LED columnar or tube-shaped light sources, characterized by high efficiency and long lifespan, providing stable and uniform illumination to meet the light intensity and spectral distribution requirements during the reaction process. An integrated liquid cooling system circulates coolant through liquid cooling inlets and outlets, effectively reducing the light source's temperature during operation and ensuring its stability and lifespan. The power supply port is rationally designed for easy connection to power supply equipment, ensuring a stable power supply to the light source.

[0014] Using an ultrasonic atomizer as the atomization device enables the efficient atomization of reactants into tiny droplets. These tiny droplets have a large specific surface area, allowing for more complete contact with light, thereby improving reaction efficiency. Ultrasonic atomizers do not require heating or high-pressure gas, avoiding the high energy consumption and safety risks associated with traditional spraying methods.

[0015] The reactor employs a combined design of a vessel body and a cooling chamber, forming a sealed reaction space. This design not only effectively prevents reactant leakage but also allows for temperature control of the reaction through the cooling chamber, ensuring the reaction proceeds under optimal conditions. The reactor is constructed from high borosilicate glass and quartz glass, with the light-transmitting areas using quartz glass, which offers excellent light transmittance and corrosion resistance, ensuring free penetration and distribution of light within the reactor. Sealing O-rings and silicone gaskets are installed at the flange-to-cover connection to effectively prevent gas or liquid leakage during the reaction process.

[0016] Adjusting the position of the internal airflow inlets and the appropriate position and flow rate of the reactant gases, such as by utilizing the Venturi effect, can increase the flow velocity of the fluid within the reactor, thereby increasing the circulation distance and effective space of the mist particles. This helps the mist particles to remain in the reactor more fully, come into contact with light, and react, thus improving reaction efficiency and product uniformity.

[0017] The reactor is equipped with a sampling port, facilitating the extraction of samples for testing and analysis during the reaction process, and enabling real-time monitoring of the reaction progress and product quality. The nebulizer features gas inlet and outlet ports and PTFE spacers, facilitating gas introduction and discharge, as well as nebulizer maintenance and replacement.

[0018] Due to its high efficiency, stability, and controllability, the ultrasonic spray microdroplet photoreactor has broad application prospects in photocatalysis, photosynthesis, and photosensitized reactions. It can provide strong technical support and experimental platforms for research in these fields. Attached Figure Description

[0022] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0023] like Figure 1-2 As shown, the components are: light source 1, reactor 2, atomizer 3, water chiller 4, electrical control box 5, internal airflow port 6, power supply port 11, liquid cooling inlet 12, liquid cooling outlet 13, lamp bead 14, flange 21, vessel body 22, coolant inlet 23, top cover 24, sampling port 25, coolant outlet 26, cooling chamber 27, gas inlet and outlet 28, and 31, spacer device 31.

[0024] A meticulously designed ultrasonic spray microdroplet photoreactor integrates multiple key components to optimize the photochemical reaction process. The reactor 2 mainly consists of a high-efficiency light source 1, a precision reactor 2, an ultrasonic atomizer 3, a water chiller 4, an intelligent electrical control box 5, and an internal airflow port 6 to enhance fluid circulation.

[0025] First, the light source 1 is selected from either an LED columnar light source 1 or a lamp tube structure light source 1 to ensure stable and suitable illumination conditions for the reaction. The internal structure of this light source 1 is ingeniously designed, integrating LED beads 14, a liquid cooling inlet 12, a liquid cooling outlet 13, and a power supply port 11. The liquid cooling system introduces coolant through the inlet, effectively absorbing the heat generated by the light source 1 before dissipating it through the outlet, ensuring the light source 1 operates continuously and efficiently without being affected by high temperatures. The power supply port 11 allows for convenient connection to an external power source, ensuring a stable power supply to the light source 1.

[0026] Reactor 2 is the core of the system, consisting of a vessel body 22, a cooling chamber 27, and a transparent reaction vessel. A top cover 24 is mounted on top of the vessel body 22, and the two are tightly connected by a flange 21 and bolts, forming a highly sealed reaction space. Within this space, the reactants undergo a chemical reaction under light, while the transparent reaction vessel allows light to penetrate unimpeded into the reaction area. A sampling port 25 is specially designed in the middle section of reactor 2, allowing researchers to easily remove samples for testing and monitor the reaction process. The cooling chamber 27 is connected to the vessel body 22, and its lower section also features a coolant inlet 23 and a coolant outlet 26 for coolant circulation. Gas inlets and outlets are also located in the middle section.

[0027] It is worth noting that reactor 2 employs a partitioned material design to enhance overall performance. The non-opaque areas are made of high borosilicate glass, whose excellent heat resistance and chemical stability protect the structure of reactor 2; while the light-transmitting areas are made of carefully selected quartz glass, whose superior light transmittance and corrosion resistance ensure that light efficiently penetrates to the reactants, promoting the photochemical reaction.

[0028] In addition, to ensure the airtightness of the reaction space, O-rings and silicone gaskets are carefully installed at the connection between flange 21 and top cover 24 to effectively prevent reactant leakage.

[0029] As another key component of the reactor 2, the ultrasonic atomizer 3 efficiently atomizes the reactants into tiny droplets, increasing the contact area between the reactants and light, thereby improving reaction efficiency. The atomizer 3 is specially equipped with gas inlet and outlet 28 for easy gas entry and exit, and is also fitted with a PTFE (polytetrafluoroethylene) spacer 31 to ensure stable operation of the equipment.

[0030] Finally, the addition of the internal airflow port 6 increases the flow rate of the fluid inside the reactor 2, further increasing the circulation distance of the mist particles within the reactor 2, promoting full contact and reaction between the reactants and light, and making the overall reaction process more efficient and uniform.

[0031] In summary, this ultrasonic spray microdroplet photoreactor 2, with its unique design and high efficiency, provides strong support for the research and application of photochemical reactions.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
