  • 洁净室装修布局和净化空调的关系!
    来源:http://www.jnyhrs.com 浏览: 发布日期:2019-02-13
    洁净室装修设计布局和净化空调系统有密切关系,净化空调系统既要服从建筑总体布局,建筑布局也要符合净化空调系统的原则,才能充分发挥相关功能的作用。净化空调的设计者不仅要了解建筑布局以考虑系统的布置,而且要给建筑布局提出要求,使其符合洁净室原理。
      Clean room decoration design layout is closely related to the purification air-conditioning system. The purification air-conditioning system should not only obey the overall layout of the building, but also conform to the principles of the purification air-conditioning system in order to give full play to the relevant functions. The designer of purified air conditioning should not only understand the layout of the building to consider the layout of the system, but also put forward requirements for the layout of the building to make it conform to the principle of clean room.
      一、洁净室的平面布局
      I. Plane layout of clean rooms
      洁净室一般包括洁净区、准洁净区和辅助区三部分。
      Clean room generally includes three parts: clean area, quasi-clean area and auxiliary area.
      洁净室的平面布置可以有以下几种方式:
      The layout of the clean room can be in the following ways:
      外廊环绕式:外廊可以有窗和无窗,兼作参观和放置一些设备用,有的在外廊内设值班采暖。外窗必须是双层密封窗。
      Outer corridor surround type: Outer corridor can have windows and no windows, both for visiting and placing some equipment, some of them have on-duty heating in the outer corridor. The outer window must be double-sealed.
      内廊式:洁净室设在外围,而走廊设在内部,这种走廊的洁净度级别一般都较高,甚至和洁净室同级。
      Inner corridor type: clean rooms are located in the periphery, while corridors are located in the interior. The cleanliness level of such corridors is generally higher, even the same level as clean rooms.
      两端式:洁净区设在一边,另一边设准洁净和辅助用房。
      Two-end type: Clean area is set on one side, and quasi-clean and auxiliary rooms are set on the other side.
      核心式:为了节约用地、缩短管线,可以洁净区为核心,上下左右被各种辅助用房和隐蔽管道的空间包围起来,这种方式避开室外气候对洁净区的影响,减少了冷热能耗,利于节能。
      Core type: In order to save land and shorten pipelines, clean area can be the core, which is surrounded by various auxiliary rooms and concealed pipes. This way avoids the impact of outdoor climate on clean area, reduces the energy consumption of cold and heat, and is conducive to energy saving.
      二、人身净化路线
      II. Personal Purification Route
      为了在操作中尽量减少人活动产生的污染,人员在进入洁净区之前,必须更换洁净服并吹淋、洗澡、消毒。这些措施即“人身净化”简称“人净”。人净用房中更换洁净服的房间应予送风,并对入口侧等其他房间保持正压,对厕所、淋浴保持少许正压,而厕所、淋浴应保持负压。相关阅读:洁净室设计和标准进行改进,尽量满足实验室的需求
      In order to minimize the pollution caused by human activities in operation, people must change their clean clothes and blow, bathe and disinfect before entering the clean area. These measures are called "personal purification" for short "human purity". The room in which clean clothes are replaced should be provided with air supply, positive pressure should be maintained on the entrance side of other rooms, a little positive pressure should be maintained on toilets and showers, and negative pressure should be maintained on toilets and showers.

      三、物料净化路线
      3. Material Purification Route
      各种物件在送入洁净区前必须经过净化处理,简称“物净”。物料净化路线与人净路线应分开,如果物料与人员只能在同一处进入洁净室,也必须分门而入,物料并先经过粗净化处理。对于生产流水线不强的场合在物料路线中间可设中间库。如果生产流水线很强,则采用直通式物料路线,有时还需要在直通路线中间设多次净化、传递设施。在系统设计上,物净用房的粗净化和精净化阶段由于会吹落很多生微粒,所以相对洁净区应保持负压或零压,如果污染危险性大则对入口方向也要保持负压。
      All kinds of objects must be purified before they are sent into the clean area, referred to as "material purification". Material purification route and human purification route should be separated. If material and personnel can only enter the clean room in the same place, they must also enter separately. Material is first treated by rough purification. When the production line is not strong, the intermediate storehouse can be set in the middle of the material line. If the production line is very strong, the direct material route is adopted. Sometimes, there are many purification and transmission facilities in the middle of the direct material route. In the system design, the coarse and fine purification stage of the material cleaning room will blow off many raw particles, so the relative clean area should maintain negative pressure or zero pressure, and if the pollution risk is high, it should also maintain negative pressure on the direction of the entrance.

      四、管线组织
      IV. Pipeline Organization
      洁净室装修设计的管线非常复杂,所以对这些管线均采用隐蔽组织方式。具体隐蔽组织方式有以下几种。
      The pipeline of clean room decoration design is very complex, so concealed organization is used for these pipelines. There are several specific ways of covert organization.
      1.技术夹层
      1. Technical interlayer
      (1)顶部技术夹层。在这种夹层内一般因送、回风管的断面大,故作为夹层内首先考虑的对象。一般将其安排在夹层的上方,其下安排电气管线。当这种夹层的底板可承受一定重量时,可以在上面设置过滤器及排风设备等。
      (1) Top technical interlayer. In this kind of sandwich, the section of air supply and return pipe is the largest, so it is the first object to be considered in the sandwich. Generally, it is arranged at the top of the sandwich layer, and electrical pipelines are arranged below it. When the bottom plate of this sandwich can bear a certain weight, filters and exhaust equipment can be installed on it.
      (2)房间技术夹层。这种方式和只有顶部夹层相比,可以减少夹层的布线与高度,可以省去回风管道返回上夹层所需的技术夹道。在下夹道内还可设回风机动力设备配电等,某层洁净室的上夹道可以兼做上一层的下夹道。
      (2) Interlayer of room technology. Compared with the top sandwich, this method can reduce the wiring and height of the sandwich and save the technical sandwich needed for the return air pipeline to return to the upper sandwich. In the lower chute, the power distribution of the power equipment of the return fan can also be set up, and the upper chute of a clean room can be used as both the upper and the lower chutes.
      1. 技术夹道(墙)
      1. Technical Gateway (Wall)
      上下夹层内的水平管线一般都要转向为竖向管线,这此竖向管线所在的隐蔽空间即技术夹道。技术夹道还可以放置不宜在洁净室内的一些辅助设备,甚至还可以作为一般回风管道或静压箱,有的可安设光管型散热器。这类技术夹道(墙)由于大多采用轻质隔断,所以当工艺调整时,可方便地进行调整。
      Horizontal pipelines in the upper and lower interlayers usually turn to vertical pipelines, which are the concealed space of the vertical pipelines, i.e. technical jackets. Technical chute can also be placed in some auxiliary equipment that is not suitable for clean rooms, or even as a general return air pipe or static pressure box, and some can be installed with light tube radiator. Because most of these technologies use light partition, they can be adjusted conveniently when the process is adjusted.
      2.技术竖井
      2. Technical Shaft
      如果说技术夹道(墙)往往不越层,则需要越层时即用技术竖井,并且经常作为建筑结构的一部分,具有永久性。由于技术竖井把各层串通起来,为了防火,内部管线安装完成后,要在层间用耐火极限不低于楼板的材料封闭,检修工作分层进行,检修门必须设防火门。不论技术夹层、技术夹道还是技术竖井,当直接兼作风道时,其内表面必须按洁净室的内表面的要求处理。
      If the technical jacket (wall) often does not cross the floor, the technical shaft will be used when it needs to cross the floor, and it will be permanent as part of the building structure. Because the technical shaft links up all the layers, in order to prevent fire, after the installation of internal pipelines, the fire resistance limit between the layers should not be lower than that of the floor, and the overhaul work should be carried out in different layers, and the overhaul door must be equipped with fire doors. Whether it is a technical interlayer, a technical chute or a technical shaft, when it is directly used as an air duct, its inner surface must be treated according to the requirements of the inner surface of the clean room.
