(2)水浴净化系统2:为保证气流压入净化液12的液面下有效分散、破碎后,仍有满足系统终端需求的风量和风压,用以透过干燥阻液系统3,在水浴净化系统2中,分散器14设计水位深度所产生的压强应不大于风机9额定风压。优选的,未工作条件下,水位深度可设置为净化液12的液面下0cm~6cm范围,或净化液12的液面上1cm~液面下2cm范围,更优选的,可设置为0cm~2cm范围。(2) Water bath purification system 2: In order to ensure that after the air flow is pressed into the purification liquid 12 to be effectively dispersed and broken under the liquid surface, there is still an air volume and air pressure that meets the system terminal requirements to pass through the drying liquid blocking system 3 and purify in the water bath. In system 2, the pressure generated by the designed water level depth of disperser 14 should not be greater than the rated wind pressure of fan 9. Preferably, under non-working conditions, the water level depth can be set to a range of 0cm to 6cm below the liquid surface of the purification liquid 12, or a range of 1cm to 2cm below the liquid surface of the purification liquid 12.

实验四:有效阻止净化液12和液体散逸,降低耗材损耗,阻隔管道污染,可靠保障使用安全。Experiment 4: Effectively prevent the purification liquid 12 and liquid from escaping, reduce the loss of consumables, block pipeline contamination, and reliably ensure safe use.

And when used as the terminal of the central circulation system, it can effectively block pipeline pollution and avoid the spread of secondary pollution caused by dust accumulation in the pipeline.
对本发明的五种实施样机进行内容物挥发量测试。为方便检测,将净化液12中的净化剂替换为氯化钠,并适当增加溶液浓度,参照标准GB/T1266-2006《化学试剂氯化钠》进行系统净化剂(氯化钠替代)挥发量模拟测试,测试方案及测试结果如下。Conduct a content volatilization test on five implementation prototypes of the present invention. In order to facilitate detection, replace the purifying agent in purifying solution 12 with sodium chloride, and increase the solution concentration appropriately. Refer to the standard GB/T1266-2006 "Chemical Reagent Sodium Chloride" to determine the volatilization of the system purifying agent (sodium chloride replacement). The simulation test, test plan and test results are as follows.
测试方法:Test Methods:
(1)取净化系统正常工作所需纯化水用量,将其与NaCl按一定比例均匀混合;(1) Take the amount of purified water required for the normal operation of the purification system, and mix it evenly with NaCl in a certain proportion;
(2)将混合溶液取样留存后,将5L混合溶液注入水浴净化系统2;(2) After sampling and retaining the mixed solution, inject 5L of the mixed solution into the water bath purification system 2;
(3)启动净化系统连续工作,按蒸发量实时定量补充纯化水,并记录;(3) Start the purification system to work continuously, replenish purified water quantitatively in real time according to the evaporation amount, and record it;
(4)如此反复,直至净化系统蒸发量为初始注入水量的4倍时,关闭净化系统;(4) Repeat this until the evaporation amount of the purification system is 4 times the initial injected water amount, then shut down the purification system;
(5)取出水浴净化系统2中剩余溶液,测量该溶液浓度,并与初始留样对比。(5) Take out the remaining solution in the water bath purification system 2, measure the concentration of the solution, and compare it with the initial sample.
因溶菌酶为可食用灭菌剂,其挥发不造成负面影响,故采用溶菌酶灭菌组未列入测试。测试对象为表1中的实施2、3、5,以及实施2(连续运行500h)耐久试验组和实施2(无干燥阻液系统3)试验组,测试结果如下表5所示:Because lysozyme is an edible sterilant and its volatilization does not cause negative effects, the sterilization group using lysozyme was not included in the test. The test objects are implementations 2, 3, and 5 in Table 1, as well as implementation 2 (continuous operation for 500 hours) durability test group and implementation 2 (non-drying liquid barrier system 3) test group. The test results are shown in Table 5 below:
表5实施样机内容物挥发量测试
Table 5 Implementation of prototype content volatilization test
从测试结果可以看出,在具有完整系统的四个试验组中,每立方米气体NaCl挥发量均在0.1mg/m3以下,可认为溶出量极低或几乎无溶出,而无干燥阻液系统3的试验组挥发量达1.175mg/m3。这表明,本发明干燥阻液系统3具有优异的控制内容物溢出性能。It can be seen from the test results that in the four test groups with complete systems, the NaCl volatilization amount per cubic meter of gas is below 0.1 mg/ m . It can be considered that the dissolution amount is extremely low or almost no dissolution, and there is no drying liquid barrier The evaporation amount of the test group of system 3 reached 1.175 mg/m 3 . This shows that the drying liquid-blocking system 3 of the present invention has excellent performance in controlling content overflow.
另一方面,本发明所采用的净化抗菌成分本身相对安全,且净化液12浓度均控制在≤1~2‰的范围内,故可确认系统内容物挥发量极微小,净化剂耗损量小,安全系数高。On the other hand, the purification and antibacterial components used in the present invention are relatively safe, and the concentration of the purification liquid 12 is controlled within the range of ≤1 to 2‰. Therefore, it can be confirmed that the amount of volatilization of the system contents is extremely small and the consumption of the purification agent is small. High safety factor.
实验五:生物、化学和物理粉尘污染一次性综合高效净化,无分步环节,无利于生物污染滋长的空间死角。Experiment 5: Comprehensive and efficient purification of biological, chemical and physical dust pollution at one time, without step-by-step procedures and no dead space in the space that is conducive to the growth of biological pollution.
本方案的净化过程在一个整体化的闭合空间4中,附带灭菌剂的气液两相流及高密度水雾,通过动态循环的方式,在扩散作用下,自然充满整个空间,粉尘、VOCs、甲醛、细菌、病毒的吸附和灭菌功能均同时完成,净化功能之间无物理空间阻隔,无净化死角,一次性综合完成所有净化功能,全面规避传统技术存在的风险。The purification process of this solution is in an integrated closed space 4, with gas-liquid two-phase flow of sterilant and high-density water mist. Through dynamic circulation, under the action of diffusion, the entire space is naturally filled with dust and VOCs. The adsorption and sterilization functions of formaldehyde, bacteria, and viruses are completed at the same time. There is no physical space barrier between purification functions and no purification dead corners. All purification functions are comprehensively completed at one time and the risks of traditional technologies are comprehensively avoided.
实验六:系统内高速气液两相流形成的高密度水雾,对超疏水阻液透气层8具有冲刷效用,实现系统自清洁功能,大幅延长系统使用寿命。Experiment 6: The high-density water mist formed by the high-speed gas-liquid two-phase flow in the system has a scouring effect on the super-hydrophobic liquid-blocking breathable layer 8, realizing the self-cleaning function of the system and greatly extending the service life of the system.
与常规过滤材料利用有一定厚度的多层细纤维交叠,对空气中尘埃通过范德华力吸附的过滤方式不同,本方案系统中的超疏水阻液透气层8主要由超疏水微孔过滤膜构成,通过其自身材料具有的超疏水特性,以及高密度均匀分布的微孔进行表面过滤。因此,污染物只能被阻挡在其过滤层 表面,不会侵入其内部,但当表面污染物累积到一定程度时,将造成其微孔堵塞,性能降低甚至寿终失效。Different from conventional filter materials that use multiple layers of overlapping thin fibers with a certain thickness to adsorb dust in the air through van der Waals forces, the superhydrophobic liquid-blocking and breathable layer 8 in this system is mainly composed of superhydrophobic microporous filter membranes , which performs surface filtration through the super-hydrophobic properties of its own material and the high-density and evenly distributed micropores. Therefore, pollutants can only be blocked in its filter layer The surface will not invade its interior, but when the surface pollutants accumulate to a certain extent, it will cause the micropores to be clogged, the performance will be reduced, and even end of life.
因此,针对超疏水阻液透气层8所具有的这一表面阻隔功能特点,利用净化液12在内部空间的动态循环过程产生的高密度水雾,对超疏水阻液透气层8内表面形成液体冲洗效果,实现了对阻水层的自清洁作用,从根本上解决了超疏水阻液透气层8表面过滤膜,易积尘形成二次污染的固有缺陷。Therefore, in view of the surface barrier function characteristic of the superhydrophobic liquid-blocking breathable layer 8, the high-density water mist generated by the dynamic circulation process of the purification liquid 12 in the internal space is used to form liquid on the inner surface of the superhydrophobic liquid-blocking breathable layer 8. The flushing effect realizes the self-cleaning effect on the water-blocking layer, which fundamentally solves the inherent defect of the filter membrane on the surface of the super-hydrophobic liquid-blocking breathable layer 8, which easily accumulates dust and causes secondary pollution.
实验七:净化液12长效、安全、可再生,广谱杀菌、杀病毒,沉淀分解粉尘及有毒有害物质,净化全过程无异味和有害物质产生。Experiment 7: Purification Liquid 12 is long-lasting, safe, and renewable. It has broad-spectrum sterilization and virus killing. It precipitates and decomposes dust and toxic and harmful substances. No odor or harmful substances are produced during the entire purification process.
常规空气净化器杀菌方式一般为高压静电、紫外光照射或光触媒等方式。其中高压静电存在产生臭氧问题,紫外照射存在衰减及无法透射问题,而光触媒则效率过低。Conventional air purifier sterilization methods generally use high-voltage static electricity, ultraviolet light irradiation or photocatalyst. Among them, high-voltage static electricity has the problem of producing ozone, ultraviolet irradiation has problems of attenuation and non-transmission, and the efficiency of photocatalyst is too low.
在本方案中,污染物在过滤过程中被净化液12所吸附,物理污染遇水后即刻被液体包容、沉降,化学污染被中和或分解,生物污染被杀灭,所有污染物均实现了无害化处理,因此从根本上阻断了污染物二次扩散的可能性。In this scheme, pollutants are adsorbed by the purification liquid 12 during the filtration process. Physical pollution is contained and settled by the liquid immediately after encountering water. Chemical pollution is neutralized or decomposed. Biological pollution is destroyed. All pollutants are achieved. Harmless treatment, thus fundamentally blocking the possibility of secondary diffusion of pollutants.
实验八:“瀑布效应”产生大量负离子,利于环境污染物沉降,有益人体健康。Experiment 8: The "waterfall effect" produces a large amount of negative ions, which is beneficial to the deposition of environmental pollutants and beneficial to human health.
众所周知,在自然界中,台风或暴雨的威力迫使雨滴反复相互碰撞,从而随着水滴的进一步分裂和破碎,产生大量覆盖大面积的超无限小水粒子和负离子,彻底净化大气,这条自然法则常被称为“台风效应”。而本方案中,外部中高压空气通过水浴净化系统2,与净化液12形成高速动态循环的气液两相流,气流、水流相互交叠碰撞,在系统内部高度还原出微型台风效应,其产生的负离子通过超疏水阻液透气层8与洁净空气混合输送至外部空间,进一步实现了对环境的整体净化。As we all know, in nature, the power of typhoons or heavy rains forces raindrops to repeatedly collide with each other. As the water droplets further split and break, a large number of ultra-infinitely small water particles and negative ions are produced covering a large area, completely purifying the atmosphere. This natural law often Known as the "typhoon effect". In this scheme, the external medium-high pressure air passes through the water bath purification system 2, and forms a high-speed dynamic circulating gas-liquid two-phase flow with the purification liquid 12. The air flow and water flow overlap and collide with each other, and the micro-typhoon effect is highly restored inside the system, which produces The negative ions are mixed with clean air and transported to the external space through the super-hydrophobic, liquid-blocking and breathable layer 8, further realizing the overall purification of the environment.
实验九:系统可具有液位保持系统20和智能控制系统21,有效保证液 位恒定,确保系统可靠性,并可根据环境变化实时调整净化程度及风量,节能环保。Experiment 9: The system can have a liquid level maintenance system 20 and an intelligent control system 21 to effectively ensure the liquid level. The position is constant to ensure system reliability, and the purification degree and air volume can be adjusted in real time according to environmental changes, saving energy and environmental protection.
充分利用成熟的多种传感器及微处理器控制技术,对内外空气污染浓度、温度、湿度、风量、液位等参数进行实时监控,并按照既定程序进行智能调节。Make full use of mature multiple sensors and microprocessor control technology to conduct real-time monitoring of internal and external air pollution concentration, temperature, humidity, air volume, liquid level and other parameters, and perform intelligent adjustments according to established procedures.
实验十:与常规过滤器相比,利用水溶液吸附净化,容污量显著提高,使用寿命长,耗材成本低。Experiment 10: Compared with conventional filters, the use of aqueous solution for adsorption and purification has significantly increased dirt holding capacity, long service life, and low cost of consumables.

  7. 利用权利要求6所述的一种防生物污染空气净化系统的净化方法, 其特征在于:Utilizing the purification method of a biological pollution prevention air purification system described in claim 6, Its characteristics are:
    首先,外部空气通过可重复使用或一次性使用的所述初效过滤层,将外部空气进行初过滤,滤除较大尺寸尘埃物之后,外部空气进入所述风机内,再通过所述风机做功,形成具有一定压强和动能的单向气流进入所述风管;First, the external air passes through the reusable or disposable primary filter layer, and the external air is initially filtered. After filtering out larger dust particles, the external air enters the fan, and then uses the fan to perform work. , forming a unidirectional airflow with a certain pressure and kinetic energy to enter the air duct;
    其次,所述风管导引增压后的气流,以与所述净化液的液面垂直或呈一定角度的方向,进入所述阻流板中的所述进风口,当气流从所述出风口高速流出时,被分散器分散和破碎,使气流与所述净化液混合为气液两相流,在此过程中,通过所述阻流板和所述锥形导流罩相互之间的所述气体通路,使气液两相流以平行于液面或与液面呈一定角度的方向,在液面下向四周横向扩散,延长分散的气液两相流在液面下的存留时间,提高气液混合效率,当所述水浴净化系统腔体内各方向的气液两相流在高速运动过程中,相互间不断循环碰撞,产生大量水珠微粒和负离子,在连续液相流、分散液相流、液珠微粒及负离子的大面积、全方位吸附作用下,空气中的尘埃粒子、VOCs、甲醛以及细菌和病毒有害物质,均被捕获并驻留在溶液中,实现全接触、全吸收;Secondly, the air duct guides the pressurized air flow into the air inlet in the baffle plate in a direction perpendicular or at a certain angle to the liquid level of the purification liquid. When the air flow flows from the outlet When the air outlet flows out at high speed, it is dispersed and broken by the disperser, so that the air flow and the purification liquid are mixed into a gas-liquid two-phase flow. The gas passage enables the gas-liquid two-phase flow to spread laterally to the surroundings under the liquid surface in a direction parallel to the liquid surface or at a certain angle to the liquid surface, thereby extending the residence time of the dispersed gas-liquid two-phase flow under the liquid surface. , improve the gas-liquid mixing efficiency. When the gas-liquid two-phase flows in all directions in the water bath purification system cavity are in high-speed motion, they continuously collide with each other, producing a large number of water droplets and negative ions, which are dispersed in the continuous liquid phase flow. Under the large-area and all-round adsorption of liquid flow, liquid droplets, and negative ions, dust particles, VOCs, formaldehyde, and harmful bacteria and viruses in the air are captured and stay in the solution, achieving full contact and full coverage. absorb;
    再次,所述水浴净化系统所净化的气流在较大的所述闭合空间的气压作用下,流向所述干燥阻液系统,通过所述防泼溅过滤层阻断所述水浴净化系统输送气流中所夹带的具有较大动能的大尺寸液珠,截流气流中一部分的较小液珠微粒,通过液体收集流道输送回所述水浴净化系统;Thirdly, the air flow purified by the water bath purification system flows to the dry liquid-blocking system under the action of the larger air pressure of the closed space, and is blocked from the air flow conveyed by the water bath purification system through the anti-splash filter layer. The entrained large-sized liquid beads with large kinetic energy and a part of the smaller liquid droplets in the intercepted air flow are transported back to the water bath purification system through the liquid collection flow channel;
    最后,所述防泼溅过滤层过滤后的气流进入所述冷凝干燥层,所述冷凝干燥层以结露和吸湿的工作方式,截流并吸附气流中剩余的大部分液珠微粒和趋于饱和的水蒸气,通过所述防泼溅过滤层及所述冷凝干燥层的气流进入所述超疏水阻液透气层表面,通过超疏水阻液透气层过滤的气流排向空气中。 Finally, the airflow filtered by the anti-splash filter layer enters the condensation drying layer. The condensation drying layer intercepts and absorbs most of the remaining liquid droplets and particles in the airflow and tends to be saturated in a dew condensation and moisture absorption mode. The water vapor passes through the anti-splash filter layer and the airflow of the condensation drying layer into the surface of the superhydrophobic, liquid-blocking and breathable layer, and the airflow filtered by the superhydrophobic, liquid-blocking and breathable layer is discharged into the air.
