  • 无尘车间防火措施怎么做好呢?
    来源:http://www.moptuan.com 浏览: 发布日期:2017-10-20
    在各式各样的灾祸中,火灾是遍及的要挟大众安全和社会发展的首要灾祸之一,除了家庭要特别注意防火之外,公共场合也是相同。我们来讲讲厂房内的东莞无尘车间该怎样做好防火措施。
    Fire is one of the most common disasters threatening public safety and social development in all kinds of disasters, and the same is true of the public except that the family should pay special attention to fire prevention. Let's talk about the workshop in Dongguan dust-free workshop how to do fire prevention measures.
    无尘车间内设有宝贵设备、仪器的房间除应契合现行国家标准《建筑设计防火标准>(GB 50016)的规则设置固定救活设备外,还应契合下列要求:
    In the dust-free workshop, the rooms with valuable equipment and instruments should be fitted with the existing national standard "code for fire protection design of buildings" (GB 50016), and the fixed maintenance equipment should be set up, and the following requirements should also be met:
    1、当设置主动喷水救活体系时,宜选用预效果式主动喷水救活体系。
    1, when the active water spraying system is set up, the pre effect active sprinkler system should be selected.
    2、当设置气体救活体系时,不该选用卤代烷1211以及能导致人员窒息和对维护目标发生二次危害的救活剂。
    2, when set up gas recovery system, should not use halogenated alkane 1211 and can cause personnel suffocation and maintenance target two times harm of life saving agent.
    无尘车间内给水排水管道的敷设方法直接影响洁净室的空气洁净度,因而在“标准”中首要要求管道尽量在洁净室外敷设,以大极限的削减无尘车间内的管道。目前,东莞无尘车间的管道安置方式有:各种干管安置在技能夹层、技能夹道、技能竖井内。
    The air cleanliness in clean room laying method of water supply and drainage pipeline directly affect the clean room, and in the "standard" in the primary piping clean as far as possible in the outdoor installation with maximum limit, cut the pipe in the clean room. At present, Dongguan resettlement pipeline clean workshop are: all kinds of dry tube placed in the interlayer, walk, skills skills skills in shaft.
    对具有上下夹层的无尘车间,给水排水干管大都设鄙人夹层内;暗装立管可安置在墙板、异型 砖、管槽或技能夹道内;支管由干管或立管引进洁净室,好从上、下夹层引进20~30 cm后再与设备二次配管相连;安装在技能夹道内的管道及阀件,可明装也可暗装。
    With the upper and lower laminated tube are set in the clean room, the interlayer water dry; concealed riser can be placed in the wall, special-shaped brick, pipe or a skill; pipe by dry pipe or a vertical tube to introduce clean room, preferably from the upper and lower interlayer introduced 20 ~ 30 cm and equipment the two is installed in the piping; skills in lined pipelines and valves, can be installed or concealed.
    东莞无尘车间均为恒温恒湿房间,而生产工艺需求的各类管道又有不同的水温要求,管表里的温差可能使管外壁结露,影响室内温湿度。因而,对于有可能结露的管道应采纳防结露措施。
    Dongguan dust-free workshop is a constant temperature and humidity room, and the production process needs of various types of pipes have different water temperature requirements, the temperature difference between the tube and the exterior wall may cause the condensation of the outer wall of the pipe, affecting indoor temperature and humidity. Therefore, the condensation prevention measures should be adopted for the pipe with possible condensation.

    防结露层外外表能够选用镀锌铁皮或铝皮作外壳,便于清洗并不发生尘埃。
    The outer surface of the anti condensation layer can be made of galvanized iron sheet or aluminum crust, which is easy to clean and does not occur dust.
    东莞无尘车间的生产工艺一般为超精细加工或要求无菌无尘,对给水体系要求较为严厉,如大规模集成电路的超纯水、医药工业的注射用水等。而且有的水体系的造价高、办理要求严厉,因而应该依据不同的要求设置体系(如纯水的不同水质要求,冷却水的不同水温、水质要求等)。
    Dongguan clean workshop production process is generally ultra fine processing or sterile, dust-free, water supply system requirements are more stringent, such as large-scale integrated circuit ultrapure water, pharmaceutical industry, injection water, etc.. In addition, some water systems have high cost and strict processing requirements, so they should be set up according to different requirements (such as different water quality requirements of pure water, different water temperature of cooling water, water quality requirements, etc.).
    过滤器的过滤层捕集微粒的作用主要有5种
    There are 5 main functions of the filter layer in capturing particles
    1.拦截效应:当某一粒径的粒子运动到纤维表面附近时,其中心线到纤维表面的距离小于微粒半径,灰尘粒子就会被滤料纤维拦截而沉积下来。
    1. intercept effect: when a particle moves to the surface of the fiber, the distance between the heart line and the fiber surface is smaller than the radius of the particle, dust particles will be intercepted and deposited by the filter fiber.
    2.惯性效应:当微粒质量较大或速度较大时,由于惯性而碰撞在纤维表面而沉积下来。
    2. inertial effect: when the particle mass is large or the velocity is large, it is deposited on the surface of the fiber because of inertia.
    3.扩散效应:小粒径的粒子布朗运动较强而容易碰撞到纤维表面上。
    3. diffusion effect: small particles of Brown motion are strong and easy to collide on the fiber surface.
    4.重力效应:微粒通过纤维层时,因重力沉降而沉积在纤维上。
    4. gravity effect: the particles are deposited on the fiber by gravitational settling when they pass through the fiber layer.
    5.静电效应:纤维或粒子都可能带电荷,产生吸引微粒的静电效应,而将粒子吸到纤维表面上。
    5. electrostatic effect: fibers or particles may carry charges to produce electrostatic effects that attract particles and attract particles to the surface of the fibers.
