  • 净化工程中空气净化处理Plan细节介绍
    来源: 浏览:次 发布日期:2020-04-17
    空气过滤器的选用布置和安装方式,应符合:初效空气过滤器不应选用浸油式过滤器;中效空气过滤器宜聚集设置在净化空气调节系统的正压段;空气过滤器或亚空气过滤器宜设置在净化空气调节系统末端,空气过滤的安装方式应简便可靠,宜检漏和更换;中效、亚、空气过滤器宜按额定风量选用;阻力、效率相近的空气过滤器宜设置在同一净化车间内。
    The selection, arrangement and installation of air filter shall be in accordance with the following requirements: the first effect air filter shall not be oil immersed; the medium effect air filter shall be set in the positive pressure section of purified air conditioning system; the high efficiency air filter or sub high efficiency air filter shall be set at the end of purified air conditioning system, and the installation method of high efficiency air filter shall be simple and reliable, leakage detection and Replacement; medium efficiency, sub high efficiency and high efficiency air filters should be selected according to the rated air volume; high efficiency air filters with similar resistance and efficiency should be set in the same purification workshop.
    细目聚集或分散式净化空气调节系统时,应综合揣摩生产手工制作的特点和净化车间空气的洁净度等级、面积、地位等圆素。凡生产手工制作连续、无尘室或净化车间面积较大时,地位聚集以及噪声把握和振动把握要旨严格的洁净室,宜采取应用聚集式净化空气调节系统。
    When determining the centralized or decentralized purified air conditioning system, the characteristics of the production process and factors such as the cleanliness level, area and location of the air in the purification workshop should be considered comprehensively. Where the production process is continuous and the clean room or purification workshop has a large area, the centralized purified air conditioning system should be used for the clean room with centralized location, strict noise control and vibration control requirements.
    空气净化工程
    净化空气调节系统如需电加热时,应选用管状电加热器,地位应布置在空气过滤器的上风侧,并应有防火安全措施。
    If the purified air conditioning system needs electric heating, the tubular electric heater shall be selected, which shall be arranged on the windward side of the high-efficiency air filter, and fire safety measures shall be taken.
    送风机可按净化空气调节系统的总送风量和总阻力值进行决定,中效、空气过滤器的阻力宜按其初阻力的两倍计算。
    The supply fan can be selected according to the total supply air volume and total resistance value of the purified air conditioning system, and the resistance of medium efficiency and high efficiency air filter should be calculated as twice of its initial resistance.
    净化工程中净化空气调节系统除直流式系统和设置值班风机的系统外,应采取防止露天污染空气通过新风口参入净化车间内的防灌倒措施。
    In addition to the DC system and the system with duty fan, the anti pouring measures shall be taken to prevent the outdoor polluted air from entering the purification workshop through the new air inlet.
    净化空气调节系统策划应合理利用回风,凡手工制作过程产生大量有害物质且局部处理不能满足卫生要旨,或对其他工序有危害时,则不应用回风。
    The design of the purified air conditioning system shall make reasonable use of the return air. Where a large number of harmful substances are produced in the process and local treatment cannot meet the health requirements, or there is harm to other processes, the return air shall not be used.
