The concentration of dissolved gas in the solution improves the efficiency and shortens the reaction time.
本领域所属技术人员可以理解的是，本发明所采用的微界面发生器在本发明人在先专利中已有体现，如申请号CN201610641119.6、CN201610641251.7、CN201710766435.0、CN106187660、CN105903425A、CN109437390A、CN205833127U及CN207581700U的专利。在先专利CN201610641119.6中详细介绍了微米气泡发生器(即微界面发生器)的具体产品结构和工作原理，该申请文件中记载了“微米气泡发生器包括本体和二次破碎件、本体内具有空腔，本体上设有与空腔连通的进口，空腔的相对的第一端和第二端均敞开，其中空腔的横截面积从空腔的中部向空腔的第一端和第二端减小；二次破碎件设在空腔的第一端和第二端中的至少一个处，二次破碎件的一部分设在空腔内，二次破碎件与空腔两端敞开的通孔之间形成一个环形通道。微米气泡发生器还包括进气管和进液管。”从该申请文件中公开的具体结构可以知晓其具体工作原理为：液体通过进液管切向进入微米气泡发生器内，超高速旋转并切割气体，使气体气泡破碎成微米级别的微气泡，从而提高液相与气相之间的传质面积，而且该专利中的微米气泡发生器属于气动式微界面发生器。Those skilled in the art can understand that the micro-interface generator used in the present invention has been embodied in the inventor's prior patents, such as application numbers CN201610641119.6, CN201610641251.7, CN201710766435.0, CN106187660, CN105903425A, Patents of CN109437390A, CN205833127U and CN207581700U. In the previous patent CN201610641119.6, the specific product structure and working principle of the micro-bubble generator (that is, the micro-interface generator) were introduced in detail. There is a cavity, the body is provided with an inlet communicating with the cavity, the opposite first and second ends of the cavity are open, wherein the cross-sectional area of the cavity is from the middle of the cavity to the first and second ends of the cavity. The second end is reduced; the secondary crushing piece is arranged at at least one of the first end and the second end of the cavity, a part of the secondary crushing piece is arranged in the cavity, and both ends of the secondary crushing piece and the cavity are open An annular channel is formed between the through holes of the micro-bubble generator. The micro-bubble generator also includes an air inlet pipe and a liquid inlet pipe." From the specific structure disclosed in the application document, we can know that its specific working principle is: the liquid enters the micron tangentially through the liquid inlet pipe. In the bubble generator, ultra-high-speed rotation and cutting of the gas make the gas bubbles break into micro-bubbles at the micron level, thereby increasing the mass transfer area between the liquid phase and the gas phase, and the micro-bubble generator in this patent belongs to the pneumatic micro-interface generation. device.
另外，在先专利201610641251.7中有记载一次气泡破碎器具有循环液进口、循环气进口和气液混合物出口，二次气泡破碎器则是将进料口与气液混合物出口连通，说明气泡破碎器都是需要气液混合进入，另外从后面的附图中可知，一次气泡破碎器主要是利用循环液作为动力，所以其实一次气泡破碎器属于液动式微界面发生器，二次气泡破碎器是将气液混合物同时通入到椭圆形的旋转球中进行旋转，从而在旋转的过程中实现气泡破碎，所以二次气泡破碎器实际上是属于气液联动式微界面发生器。其实，无论是液动式微界面发生器，还是气液联动式微界面发生器，都属于微界面发生器的一种具体形式，然而本 发明所采用的微界面发生器并不局限于上述几种形式，在先专利中所记载的气泡破碎器的具体结构只是本发明微界面发生器可采用的其中一种形式而已。此外，在先专利201710766435.0中记载到“气泡破碎器的原理就是高速射流以达到气体相互碰撞”，并且也阐述了其可以用于微界面强化反应器，验证本身气泡破碎器与微界面发生器之间的关联性；而且在先专利CN106187660中对于气泡破碎器的具体结构也有相关的记载，具体见说明书中第[0031]-[0041]段，以及附图部分，其对气泡破碎器S-2的具体工作原理有详细的阐述，气泡破碎器顶部是液相进口，侧面是气相进口，通过从顶部进来的液相提供卷吸动力，从而达到粉碎成超细气泡的效果，附图中也可见气泡破碎器呈锥形的结构，上部的直径比下部的直径要大，也是为了液相能够更好的提供卷吸动力。In addition, the previous patent 201610641251.7 records that the primary bubble breaker has a circulating liquid inlet, a circulating gas inlet and a gas-liquid mixture outlet, and the secondary bubble breaker communicates the feed port with the gas-liquid mixture outlet, indicating that the bubble breaker is both It needs to be mixed with gas and liquid. In addition, it can be seen from the following drawings that the primary bubble breaker mainly uses circulating liquid as power, so in fact, the primary bubble breaker belongs to the hydraulic micro-interface generator, and the secondary bubble breaker is a gas-liquid breaker. The mixture is simultaneously fed into the elliptical rotating ball for rotation, so that the bubbles are broken during the rotation, so the secondary bubble breaker is actually a gas-liquid linkage type micro-interface generator. In fact, both hydraulic micro-interface generators and gas-liquid linkage micro-interface generators belong to a specific form of micro-interface generators. However, the micro-interface generators used in the present invention are not limited to the above-mentioned forms. , the specific structure of the bubble breaker described in the prior patent is only one of the forms that the micro-interface generator of the present invention can take. In addition, the previous patent 201710766435.0 recorded that "the principle of the bubble breaker is to achieve high-speed jets to achieve gas collision", and also stated that it can be used in micro-interface enhanced reactors to verify the relationship between the bubble breaker and the micro-interface generator. and the prior patent CN106187660 also has related records for the specific structure of the bubble breaker, see the specific description in paragraphs [0031]-[0041], and the accompanying drawings, which are related to the bubble breaker S-2 The specific working principle of the bubble breaker is explained in detail. The top of the bubble breaker is the liquid phase inlet, and the side is the gas phase inlet. The liquid phase entering from the top provides the entrainment power, so as to achieve the effect of crushing into ultra-fine bubbles, which can also be seen in the accompanying drawings. The bubble breaker has a conical structure, and the diameter of the upper part is larger than that of the lower part, so that the liquid phase can provide better entrainment power.
由于在先专利申请的初期，微界面发生器才刚研发出来，所以早期命名为微米气泡发生器(CN201610641119.6)、气泡破碎器(201710766435.0)等，随着不断技术改进，后期更名为微界面发生器，现在本发明中的微界面发生器相当于之前的微米气泡发生器、气泡破碎器等，只是名称不一样。Since the micro-interface generator was just developed in the early stage of the previous patent application, it was named as micro-bubble generator (CN201610641119.6), bubble breaker (201710766435.0), etc., and later changed its name to micro-interface generator with continuous technological improvement. The micro-interface generator in the present invention is equivalent to the previous micro-bubble generator, bubble breaker, etc., but the names are different.
综上所述，本发明的微界面发生器属于现有技术，虽然有的微界面发生器属于气动式微界面发生器类型，有的微界面发生器属于液动式微界面发生器类型，还有的属于气液联动式微界面发生器类型，但是类型之间的差别主要是根据具体工况的不同进行选择，另外关于微界面发生器与反应器、以及其他设备的连接，包括连接结构、连接位置，根据微界面发生器的结构而定，此不作限定。To sum up, the micro-interface generator of the present invention belongs to the prior art, although some micro-interface generators belong to the type of pneumatic micro-interface generators, some micro-interface generators belong to the type of hydraulic micro-interface generators, and some are of the type of hydraulic micro-interface generators. It belongs to the type of gas-liquid linkage micro-interface generator, but the difference between the types is mainly selected according to the specific working conditions. In addition, the connection between the micro-interface generator and the reactor and other equipment, including the connection structure, connection position, It depends on the structure of the micro-interface generator, which is not limited.

The cleaned droplets form a liquid level at the bottom of the tank. When the liquid level rises to the middle of the tank body 10, close the upper water delivery valve and open the stirring paddle 104 at the bottom to 200 rpm. Since the installation direction of the blades of the stirring paddle 104 is downward, the liquid above the blades will be pumped to both sides below, and vortices will be formed on both sides of the stirring paddle 104, and the two sides of the lower part of the tank body 10 will be washed and cleaned. At the same time, the water channel below is opened, and the input water flow cleans the side wall of the tank under the action of the stirring paddle 104. After flushing for 30 minutes, close the water delivery valve, reduce the speed to 100 rpm/min, and pass the outlet on both sides of the lower end of the tank 10. The liquid outlet 102 discharges water, closes the liquid outlet 102, and reduces the rotational speed to 50 rpm/min.
(2)消毒：打开高温蒸汽管线，通入121～180℃，3公斤蒸汽进行杀菌消毒，在通蒸汽的同时维持搅拌速率50rpm/min，使得罐体内的蒸汽均匀分布。在蒸汽消毒的同时可以打开罐体上侧内壁的超声波灭菌装置105辅助灭菌。30～50min后关闭蒸汽管线，蒸汽冷凝后的水从罐底两侧的出液口102排放，关闭出液口102，冷却罐体至室温。(2) Disinfection: Open the high-temperature steam pipeline, pass 121-180°C, 3 kg of steam for sterilization, and maintain the stirring rate of 50 rpm/min while passing the steam, so that the steam in the tank is evenly distributed. During the steam sterilization, the ultrasonic sterilization device 105 on the inner wall of the upper side of the tank can be opened to assist the sterilization. After 30 to 50 minutes, the steam line is closed, the water after steam condensation is discharged from the liquid outlet 102 on both sides of the tank bottom, the liquid outlet 102 is closed, and the tank body is cooled to room temperature.
上述喷淋***工作过程中的操作以及工艺参数完全由PLC(或DCS，PLC和DCS)的控制***控制，控制***与罐体10上各传感器相连接，实现自动化智能化控制，节约人力成本。The operation and process parameters in the working process of the spray system are completely controlled by the control system of PLC (or DCS, PLC and DCS).
