  • 空气净化工程设计需要注意什么?
    来源: 浏览: 发布日期:2020-07-04
    空气净化工程设计需要注意什么?净化工程是一个整体,每一个环节都要细致检查,只有做好每一个细节,才能让整个系统完善,发挥大的价值。如何做好这些,以下八大要点需要我们注意。
    What should be paid attention to in the design of air purification project? The purification project is a whole, and every link should be carefully checked. Only by doing well in every detail can the whole system be improved and brought into full play. How to do these well, the following eight points need our attention.
    1.净化系统
    1. Purification system
    室内的空气净化系统可分为水平层流、垂直层流和乱流。选择气流形式一则参照惯例,二则取决于房间的工作参数。
    Indoor air purification system can be divided into horizontal laminar flow, vertical laminar flow and turbulent flow. The choice of air flow mode is based on the Convention and the working parameters of the room.
    2.洁净工程的洁净度与换气次数
    2. Cleanliness and air change frequency of cleaning engineering
    房间的洁净度取决于单位时间的换气次数,因此慎密考虑房间的工作性质、以及生产工艺要求,再决定净化系统的技术参数。
    The cleanliness of the room depends on the ventilation rate per unit time. Therefore, the technical parameters of the purification system should be determined after careful consideration of the working nature of the room and the production process requirements.
    3.净化工程结构
    3. Purification engineering structure
    为了保证气流几乎不受干扰,就必须进行结构设计,必要的谨慎可以防止房间里任何地方的灰尘积累。
    In order to prevent the accumulation of dust in the room, the structure must be carefully designed to prevent air flow from accumulating.
    4.净化工程设计方案
    4. Design scheme of purification project
    要确定设计方案,必须先对房间的工作性质以及其中的气流条件进行认真的考虑。发尘量大的车间不宜采用地面送风形式,洁净度要求高的车间应尽可能远离其它车间。
    In order to determine the design scheme, it is necessary to carefully consider the working nature of the room and the air flow conditions in it. The workshop with large dust emission should not adopt the form of ground air supply, and the workshop with high cleanliness requirements should be as far away from other workshops as possible.
    5.净化材料
    5. Purification materials
    作为洁净室顶棚,墙面和地板的材料必须是不宜破裂、不易沾颗粒,以及几乎不起尘的材料,另外根据房间不同的工作条件,还必须考虑材料的化学性能是否稳定。
    As the ceiling of clean room, the wall and floor must be made of materials that are not easy to crack, particles and dust. In addition, according to the different working conditions of the room, it is also necessary to consider whether the chemical properties of the materials are stable.
    6.净化工程中压力和气流
    6. Pressure and air flow in purification engineering
    为了保证房间的洁净度,必须防止外面污染气流进入室内,要达到这个目的,房间里必须保持正压。为了获得所要求的房间压力,必须补充适当的新鲜空气。
    In order to ensure the cleanliness of the room, it is necessary to prevent the air pollution from outside into the room. To achieve this goal, the room must maintain positive pressure. In order to obtain the required room pressure, appropriate fresh air must be supplied.
    7.净化辅助设备
    7. Purification auxiliary equipment
    必要时还得安置一些辅助设备:如新风口的空气指示仪,隔断上的传递窗等。这些设备必须适合房间的要求,并且必须真正了解其功能。
    If necessary, some auxiliary equipment should be installed, such as the air indicator of the new air outlet, the transmission window on the partition, etc. These devices must be suitable for the requirements of the room and must really understand its function.
    8.净化中人和物的控制
    8. Control of human and material in purification
    人和物是洁净室的主要尘源,因此必须充分控制,例如:在进入净化房前,所有的人都要经过人净系统,更换无尘衣,并且要接受净化系统功能的基本教育。
    People and objects are the main dust sources of the clean room, so it must be fully controlled. For example, before entering the purification room, all people should go through the personal purification system, change the dust-free clothes, and receive the basic education on the functions of the purification system.
    9.净化工程给排水和送风装置及电源
    9. Water supply and drainage and air supply device and power supply of purification project
    根据所要运行的车间,提供必须的给排水装置,送风装置和电源,这些装置和所涉及的设备必须易于使用和设计,同时不得有勃于空气净化系统。
    According to the workshop to be operated, necessary water supply and drainage devices, air supply devices and power supply shall be provided. These devices and equipment involved must be easy to use and design, and shall not be superior to the air purification system.
