空气净化工程洁净工作台的原理及介绍

There are usually some clean workbenches in the purification room, but the meticulous application method is not well understood, assuming that the operation error will have an impact on the overall purity. So today we will introduce the characteristics and principles of clean workbench, so that we can better use this equipment.

洁净工作台是一种净化设备，可以除尘、除菌，提供一个良好的工作环境，将污染的空气排出，避免对人和环境构成的危害，在微生物实验室中运用较多，还有医院手术室、精密电子等行业也有应用。

Clean workbench is a kind of purification equipment, which can remove dust and bacteria, provide a good working environment, discharge polluted air, avoid harm to human and environment. It is widely used in microbiological laboratory, hospital operating room, precision electronics and other industries.

洁净工作台特性：1、洁净度等级为100级的操作环境，关于粒径≥0.5μm的尘埃≤3.5颗/升。2、水平层流型或垂直层流型。3、采用超薄型无隔板高效空气过滤器，占用空间小。4、采用触摸式电子控制面板，风机风量可无级调理，保证工作区的风速不断处于理想状态。5、不锈钢工作台面，有机玻璃围挡，可配备紫外灯远程控制电气接口。

Clean workbench characteristics: 1. Cleanliness level of 100 operating environment, with respect to particle size (> 0.5 um) of dust (< 3.5 particles/liter). 2. Horizontal laminar flow pattern or vertical laminar flow pattern. 3. Ultra-thin non-baffled high-efficiency air filter, occupying less space. 4. Touch-type electronic control panel is used to stepless adjust the air volume of the fan to ensure that the wind speed in the working area is constantly in an ideal state. 5. Stainless steel working table, plexiglass enclosure, can be equipped with ultraviolet lamp remote control electrical interface.

洁净工作台结构：采用直接智能控制方式，设有风机、照明、除静电等开关。整个机箱采用薄钢板制造，外表烤漆，活动灵活，运用便当，易于清洁。

Clean workbench structure: direct intelligent control mode is adopted, with blower, lighting, static electricity removal switch, etc. The whole chassis is made of thin steel plate, with paint on the outside, flexible movement, convenient use and easy cleaning.

洁净工作台原理：

Principle of Clean Workbench:

洁净环境是在特定的空间内，洁净空气(进滤空气)按设定的方向活动而构成的。以气流方向来分，现有的超净工作台可分为垂直式，由内向外式以及侧向式。从操作质量和对环境的影响来思索，以垂直式较优越。由供气滤板提供的洁净空气以一个特定的速度降落经过操作区，在大约操作区的中间分开，由前端空气吸入孔和后吸气窗吸走，在操作区下部前后部吸入的空气混合在一同，并由鼓风机泵入后正压区，在机器的上部，30%的气体经过排气滤板从顶部排出，大约70%的气体经过供氧滤板重新进入操作区。为补充排气口排出的空气，同体积的空气经过操作口从房间空气中得到补充。这些空气不会进入操作区，只是构成一个空气屏障。

Clean environment is made up of clean air (inlet and filter air) moving in a given direction in a specific space. According to the direction of airflow, the existing ultra-clean worktable can be divided into vertical, internal-external and lateral. Considering the operation quality and environmental impact, the vertical type is superior. The clean air provided by the air supply filter plate falls through the operation area at a specific speed, separates in the middle of the approximate operation area, is sucked away by the front air suction hole and the rear air suction window, and is mixed with the air sucked in the lower part of the operation area, and is pumped into the positive pressure area after the blower. In the upper part of the machine, 30% of the air is discharged from the top through the exhaust filter plate, and about 70% of the air is discharged from the top. The body enters the operation area again through the oxygen supply filter plate. To supplement the air discharged from the exhaust port, the same volume of air is supplied from the room air through the operating port. These air will not enter the operating area, but constitute an air barrier.

当我们在净化室内运用洁净工作台的时分需求留意性能特性、结构特性、工作原理等方面的学问，才干更好的坚持维护净化的环境。
