  • 净化工程车间对防火设计有什么要求?
    来源:最新澳门网址大全 浏览: 发布日期:2019-11-08
      天气逐渐变冷,干燥,到处都是静电,净化工程除了有防静电地板外,还需要做防火措施。在净化工程中有贵重仪器设备的房间内安装灭火设施时,除现行国家标准《建筑设计防火规范》(GB 50016)的规定外,还应满足以下要求:
      The weather is getting cold and dry, and there is static electricity everywhere. In addition to the anti-static floor, the purification project also needs to take fire prevention measures. In addition to the current national standard code for fire protection design of buildings (GB 50016), the following requirements shall also be met when installing fire-fighting facilities in rooms with valuable instruments and equipment in the purification project:
      1. 设置自动喷水灭火系统时,应采用预动作自动喷水灭火系统。
      1. When the automatic sprinkler system is set, the pre action automatic sprinkler system shall be used.
      2. 在设置气体灭火系统时,不能使用卤化1211和对被保护对象造成窒息和二次伤害的灭火剂。
      2. When the gas fire extinguishing system is set, the halogenated 1211 and the fire extinguishing agent that causes suffocation and secondary injury to the protected object shall not be used.
      本工程给排水管道的铺设方式直接影响净化工程的空气清洁度。因此,在《规范》中,要求尽可能地在净化工程外铺设管道,从而在很大程度上减少净化工程内的管道。目前,净化工程的管道布置有:各种主管道布置在技术中间层、技术衬层、技术竖井。对于上下夹层净化工程,主给排水管道多位于下层夹层。暗装立管可布置在墙板、异型砖、管道槽或技术巷;支管由干管或立管导入洁净室,再由干管或立管导入设备上下层20-30cm后与设备的二次管连接。技术隧道内安装的管道和阀门可以公开安装,也可以秘密安装。
      The laying method of water supply and drainage pipes in this project directly affects the air cleanliness of purification project. Therefore, in the code, it is required to lay pipelines outside the purification project as much as possible, so as to reduce the pipelines in the purification project to a large extent. At present, the pipeline layout of purification project includes: various main pipelines are arranged in the technical middle layer, technical lining layer and technical shaft. For the upper and lower interlayer purification project, the main water supply and drainage pipes are mostly located in the lower interlayer. The concealed riser can be arranged in the wall panel, special brick, pipe slot or technical lane; the branch pipe is led into the clean room by the main pipe or riser, and then led into the upper and lower 20-30cm of the equipment by the main pipe or riser, and then connected with the secondary pipe of the equipment. The pipes and valves installed in the technical tunnel can be installed in public or in secret.
     空气净化工程
      本项目均为恒温恒湿房,生产过程中需要的各类管道均有不同的水温要求。管道内外的温差会使管道外壁变形,影响室内的温湿度。因此,对于可能产生结露的管道,应采取防结露措施。
      The project is a constant temperature and humidity room, and all kinds of pipes required in the production process have different water temperature requirements. The temperature difference inside and outside the pipeline will make the outer wall of the pipeline deformed and affect the indoor temperature and humidity. Therefore, anti condensation measures should be taken for the pipelines that may produce condensation.
      防结露层的外表面可采用镀锌板或铝皮制成,便于清洁,不产生粉尘。
      The outer surface of anti condensation layer can be made of galvanized sheet or aluminum sheet, which is convenient for cleaning and does not produce dust.
      净化工程的生产过程通常是超细加工或无菌无尘的。对供水系统的要求比较严格,如大型集成电路用超纯水、制药工业用注射用水等。而有些水系统成本高,管理要求严格,所以应该根据不同的要求来设置系统(如不同水质对纯水的要求、冷却水温度、水质要求等)。
      The production process of purification engineering is usually superfine processing or sterile and dust-free. The requirements of water supply system are strict, such as ultra pure water for large integrated circuit, injection water for pharmaceutical industry, etc. Some water systems have high cost and strict management requirements, so we should set up systems according to different requirements (such as different water quality requirements for pure water, cooling water temperature, water quality requirements, etc.).
      为了集中保证严格的制度要求,也有利于管理和节约运营成本。目前,净化工程的生产工艺大部分是技术发展迅速的高新技术产业,如大型集成电路、生物制药等。这些生产部门产品更新换代快,生产流程变化大,所以在管道设计上要留有足够的余地。
      In order to ensure strict system requirements, it is also conducive to management and operation cost saving. At present, the production process of purification engineering is mostly high-tech industries with rapid technological development, such as large-scale integrated circuits, biopharmaceuticals, etc. The products of these production departments are updated quickly and the production process changes greatly, so there should be enough room for pipeline design.
