  • 制药净化车间排风系统的常见问题
    来源:最新澳门网址大全 浏览: 发布日期:2020-04-30
    在药品生产用洁净室中,常常在产品生产过程中使用或生产各种酸性和碱性物质、有机溶剂和一般气体、特种气体;在致敏性药物、某些甾体药物、高活性、有毒性药物生产过程还会有相应的有害物质排出或泄露入洁净室内,为此对于上述产品用洁净室内可能排出各种有害物质、气体或粉尘的生产工艺设备或工序设置局部排风装置或全室排风装置,按生产工艺过程排出的废气的类型可将排风系统大体划分为下列几种类型。
    In the clean room for drug production, various acidic and alkaline substances, organic solvents, general gases and special gases are often used or produced in the production process of products; in the production process of sensitizing drugs, some steroidal drugs, highly active and toxic drugs, corresponding harmful substances will be discharged or leaked into the clean room, so the above products may be discharged from the clean room The production process equipment or process of various hazardous substances, gases or dust shall be equipped with local exhaust device or whole room exhaust device. According to the type of exhaust gas discharged in the production process, the exhaust system can be roughly divided into the following types.
    1、一般排风系统:生产辅助用室、生活用室等排出的一般废气,一般不需要处理直接排入大气。
    1. General exhaust system: general exhaust gas discharged from auxiliary production room, living room, etc. generally does not need to be treated and directly discharged into the atmosphere.
    2、有机气体排风系统:在生产中使用各类有机物质作为原辅材料时,将会在相关场所或设备处散发有机物质的气体,对于这类场所或设备均应设置排风装置。排风系统中的有机气体要进行相应的处理,再排入大气。
    2. Organic gas exhaust system: when all kinds of organic substances are used as raw and auxiliary materials in production, the gases will emit organic substances in relevant places or equipment, and exhaust devices shall be set for such places or equipment. The organic gas in the exhaust system shall be treated accordingly and then discharged into the atmosphere.
    3、酸性气体排风系统:在产品生产中时有酸性气体排出,在这类排风系统通常设置湿式洗气吸收塔,处理后排入大气。

    3. Acid gas exhaust system: in the production of products, acid gas is discharged. In this type of exhaust system, a wet scrubbing absorption tower is usually set, which is discharged into the atmosphere after treatment.
    4、碱性气体排风系统:在产品生产中时有酸性气体排出,在这类排风系统通常设置湿式洗气吸收塔,处理后排入大气。
    4. Alkaline gas exhaust system: acid gas is discharged during the production of the product. In this type of exhaust system, a wet scrubbing absorption tower is usually set, which is discharged into the atmosphere after treatment.
    5、热气体排风系统:对生产过程中的各种炉子、高温灭菌设备等均有热气排出,由于排气温度较高,有时可采用热回收等方式进行处理,若排气量较小或不便进行处理时,在采取必要的隔热措施后直接排入大气。
    5. Hot gas exhaust system: all kinds of furnaces, high-temperature sterilization equipment, etc. in the production process are discharged with hot gas. Due to the high exhaust temperature, sometimes heat recovery and other methods can be used for treatment. If the exhaust volume is small or inconvenient for treatment, it can be directly discharged into the atmosphere after taking necessary heat insulation measures.
    6、含粉尘的排风系统:不同的生产工艺过程中,排气中的粉尘性质、浓度均不同。对于某些含尘浓度很高时,则要使用除尘设备对排气进行过滤,满足要求后排入大气。
    6. Exhaust system with dust: in different production processes, the dust properties and concentrations in the exhaust are different. When the dust concentration is very high, the dust removal equipment shall be used to filter the exhaust gas and discharge it into the atmosphere after meeting the requirements.
    7、特殊气体排气系统:对于产生特殊气体(属于易燃易爆或有毒甚至剧毒或有腐蚀性的气体)要防止排气系统中产生化学反应,要划分排气系统,选用专用的废气处理装置,达到排放标准后排入大气。
    7、 Special gas exhaust system: for the generation of special gas (belonging to flammable, explosive, toxic, even highly toxic or corrosive gas), chemical reaction shall be prevented in the exhaust system. The exhaust system shall be divided, and special waste gas treatment device shall be selected. The large gas shall be discharged after reaching the emission standard.
    8、药品生产中有害、有毒的排风系统:在一些特殊药品(如强致敏性药物、某些甾体药物以及高活性、有毒药物)房间的排风口,应安装过滤器,降低污染后排入大气。
    8. Harmful and toxic exhaust system in drug production: high efficiency filter shall be installed at the air outlet of some special drugs (such as highly sensitized drugs, some steroids and highly active and toxic drugs) room to reduce pollution and then discharge into the atmosphere.
