超声波紫外线杀菌器Ultrasonic ultraviolet sterilizer

一、产品介绍Product introduction

超声波紫外线杀菌器是今晚六会彩开什么号码技术人员通过大量的研究试验,在原紫外线杀菌器基础上研发出来的新一代高效、纯物理工艺的水处理杀菌装置,它集生物学、声学、光学、机械、流体力学、电子等综合学科于一体,体现了力的、热的、光的物理作用,因此反应时间短,杀菌速度快,同时,频率在20KHZ以上的超声波能够彻底干净的清洗紫外线石英套管,防止石英管外壁在高盐度海水中结垢,永久保持石英套管良好的透光率和紫外线灯的杀菌率,不使用外加的化学添加剂,不产生二次污染,是一种高效、经济、快速、环保、绿色的广谱水处理杀菌装置。

Ultrasonic ultraviolet sterilizer is Qinhuangdao Shijiyuan Water Treatment Technology Co.,Ltd technical staff through a large number of research trials, in the original basis of ultraviolet sterilization device developed by a new generation of highly efficient, a purely physical process water treatment sterilization device. It sets the biology, acoustic, optical, mechanical, fluid mechanics, electronics and other comprehensive disciplines in one, Reflected power, heat, light physical effects, thus the reaction time is short, fast sterilizing speed.At the same time, the ultrasonic frequencies above 20KHZ can thoroughly clean cleaning UV quartz tube, quartz sleeve to permanently maintain good transmittance and ultraviolet light disinfection rate, without the use of additional chemical additives, no secondary pollution, is an efficient, economic, fast, environmental protection, green broad-spectrum disinfection of water treatment device.

二、工作原理Working principle

被处理水经进水口进入超声波紫外线杀菌器机体,波长在254nm的强紫外线C(UVC)对水流进行均匀照射,达到广谱杀菌效果,同时,频率在20KHZ以上的超声波对水具有空化、混合、裂解、氧化、推流、杀菌、灭藻、清洗、除垢防垢等一系列作用,超声波空化实现了辅助杀菌和对有机物的降解,其产生的局部激波能使被处理水产生紊流现象,使水与紫外线更加充分均匀的接触,使杀菌更高效;同时超声波对腔体和石英套管起到了关键的清洗、除垢、防垢作用,使紫外线灯在高盐度海水内不结垢、不污染,长期保持良好的杀菌效果。

The treated water into the ultrasonic ultraviolet sterilizers from the inlet, ultrasonic frequencies above 20KHZ have a series of functions of cavitation, mixed, pyrolysis, oxidation, plug flow, sterilization, algae removal, cleaning, descaling and antiscaling to water, ultrasonic cavitation to achieve the auxiliary sterilization and degradation of toxic organic compounds, which produces a local shock can be processed to generate turbulence phenomenon of water, make water and ultraviolet more fully and uniformly contact, to achieve more efficient sterilizing effect; at the same time of ultrasonic wave on the cavity and a quartz tube has played a critical role in the cleaning, descaling, anti-scaling effects, combined with 254nm wavelength ultraviolet C irradiation (UVC ) flow, to achieve further broad-spectrum sterilization, to make the treated water in a short period of time to achieve very good sterilization effect.

紫外线是一种肉眼不可见光,根据波长的不同可细分为UVA(315-400nm)UVB(280-315nm)和UVC(200-280nm),其中UVC最易被DNA(核糖核酸)吸收,紫外线杀菌设备使用的就是UVC,当水中的细菌、病毒、藻类、生物等受到一定剂量的UVC(波长254nm)照射后,其细胞的DNA、RNA结构再生无法进行,细菌病毒丧失自我复制的能力,从而达到水的杀菌和净化的目的,因此已被广泛应用于各类污水、给水、中水、地表水、纯水、净水、景观水、泳池水及海水等各种水质的杀菌消毒,细菌杀灭率在99%以上。

UV is invisible light, according to the different wavelengths can be subdivided into UVA (315-400nm) UVB (280-315nm) and UVC (200-280nm), which UVC are most vulnerable to DNA (RNA) absorption, UV device is UVC. When the bacteria, viruses, algae, biological, and other by a certain dose of UVC (wavelength 254nm) irradiation, the DNA, RNA structure of the cells, can not be recycled, loss of self-replicating bacteria and viruses the ability to achieve water sterilization and purification purposes, It has been widely used in various types of wastewater, water supply, water, surface water, pure water, water purification, water landscape, water and sea water swimming pool and other water disinfection, to kill bacteria rate of 99%.

但在实际应用过程中,由于水质差、硬度高、细菌含量大等因素,很容易在紫外线灯的石英管壁上吸附有机物、生物粘泥、细小颗粒等杂质,并且在具有含盐高的水质当中工作,很容易在石英管壁上结垢,导致紫外线辐射能量低、穿透力弱,大大降低杀菌效率,严重影响了杀菌效果。

But in the actual application process, due to poor water quality, high hardness, bacteria and other factors, it is easy adsorpt organic matter, biological slime, fine particles and other impurities on the ultraviolet light quartz wall, and work in the water which has a certain hardness ,it is easy scaling on the quartz wall, resulting in low energy UV radiation, through weak and greatly reduce the efficiency of sterilization, seriously affected the bactericidal effect.

 

世纪源超声波紫外线杀菌器充分利用超声波的超声空化效应,不但克服了以上缺点,能永远保持石英套管较高的透光率,同时还具有辅助杀菌作用。超声空化即:液体中的微小气泡核在超声波作用下产生振动,当声压达到一定值时,气泡将继续膨胀,然后突然闭合,在气泡闭合时产生冲击波,这种膨胀、闭合、振荡等一系列动力学过程称为超声空化。这些小气泡急速崩溃时在气泡内产生了高温(5000K)、高压(上千个大气压),并且由于气泡周围的液体高速冲入气泡,而在气泡附近的液体中产生了强烈的局部激波,也形成了局部的高温高压,从而产生了超声波的混合、清洗、粉碎、裂解、推流、氧化、杀菌、灭藻、除垢、防垢等一系列的作用。

Shijiyuan ultrasonic UV sterilizers make full use of ultrasonic cavitation effect. It not only overcome the above shortcomings, can always maintain a high transmittance quartz sleeve, and also has assisted bactericidal effect. Ultrasonic cavitation, namely: The tiny bubbles core vibration in the liquid under the action of the ultrasonic, when the pressure reaches a certain value, the bubble will continue to expand, and then suddenly closed, the shock wave generated when the bubble is closed. This expansion, closure, vibration, etc. series of dynamic process is called cavitation. These small bubbles rapidly generated produce the high temperature (5000K), high voltage (thousands of atmospheres) within the bubble collapse, and because of the fluid around the bubbles high-speed into the air bubbles, in the vicinity of the bubbles in  the liquid generated a strong local shock, also formed a local high temperature and pressure, resulting in a mix, cleaning, crushing, cracking, plug-flow, oxidation, bacteria, algae, cleaning, and a series of anti-scaling effect of ultrasonic.

超声波紫外线杀菌器配有紫外线照射强度自动监测系统,当石英管污染,紫外线照射强度降低时,会自动启动超声波装置对石英管进行清洗,恢复照射强度后,清洗自动停止;超声波自动清洗装置可实现手动和自动两种工作方式。

Ultrasonic UV sterilizers equipped with ultraviolet radiation intensity automatic monitoring system. When quartz tube pollution ,the ultraviolet radiation intensity decreased.It will automatically start ultrasonic devices to quartz tube cleaning.,the cleaning to be automatic stop when it restores illuminate intensity. Ultrasonic automatic cleaning device can achieve both manual and automatic to work.
