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;中效空气过滤器宜集中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: oil immersed filter shall not be selected for primary air filter; medium efficiency air filter shall be set in positive pressure section of purified air conditioning system; high efficiency air filter or sub high efficiency air filter shall be set at the end of clean air conditioning system; the installation method of high efficiency air filter shall be simple and reliable, and leakage detection shall be conducted 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.
确定集中或分散式净化空气调节系统时,应综合考虑生产工艺的特点和净化车间空气的洁净度等级、面积、位置等因素。凡生产工艺连续、无尘室或净化车间面积较大时,位置集中以及噪声控制和振动控制要求严格的洁净室,宜采用集中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 the cleanliness level, area and location of the air in the purification workshop should be comprehensively considered. When the production process is continuous, dust-free room or purification workshop has a large area, the clean room with centralized location and strict requirements for noise control and vibration control should adopt centralized purified air conditioning system.
净化空气调节系统如需电加热时,应选用管状电加热器,位置应布置在空气过滤器的上风侧,并应有防火安全措施。
空气净化工程
If the purified air conditioning system needs electric heating, the tubular electric heater should be selected, and the position should be arranged on the windward side of the high efficiency air filter, and there should be fire safety measures.
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选择,中效、空气过滤器的阻力宜按其初阻力的两倍计算。
The forced draft fan can be selected according to the total air supply volume and total resistance value of the purified air conditioning system, and the resistance of medium efficiency and high efficiency air filters should be calculated as twice of the 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,应采取防止室外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 once through system and the system equipped with duty fan, the anti pouring measures should be taken to prevent the outdoor polluted air from entering the purification workshop through the new air outlet.
净化空气调节系统设计应合理利用回风,凡工艺过程产生大量有害物质且局部处理不能满足卫生要求,或对其他工序有危害时,则不应用回风。
The return air should be reasonably used in the design of purified air conditioning system. When a large amount of harmful substances are produced in the process and the local treatment can not meet the sanitary requirements, or it is harmful to other processes, the return air shall not be used.
