  • 实验室通风柜的选择及注意事项
    来源:http://www.jnyhrs.com/ 浏览: 发布日期:2018-06-19
    在现代化实验室设备中有通风柜、中央实验台、边台、药品柜、器皿柜、气瓶柜等,其中通风柜是生化实验室设备中担负着十分重要的功能,是必不可少的设备。
    In the modern laboratory equipment, the ventilation cabinet, the central experimental platform, the edge platform, the drug cabinet, the container cabinet, the cylinder cabinet and so on, of which the ventilator is a very important function in the biochemical laboratory equipment, and it is a necessary equipment.
    因此,选择通风柜是实验室建设中的重要问题,必须引起足够的重视通风柜的功能中最主要的是排气功能,在化学实验室中,实验操作时会产生各种有害气体、臭气、湿气以及易燃、易爆、腐蚀性物质,为了保护使用者的安全,防止实验中的污染物质向实验室扩散,在污染源附近要使用通风柜,以往通风柜使用台数较少,只在特别有害且危险的气体及产生大量热的实验中使用。通风柜只担负实验台的辅助功能。
    Therefore, the selection of the ventilator is an important problem in the construction of the laboratory. It is necessary to attract enough attention to the exhaust function in the function of the ventilator. In the chemical laboratory, all kinds of harmful gases, stench, wet gas, inflammable, explosive and corrosive substances will be produced in the laboratory operation, in order to protect the safety of the users. To prevent the contamination from the experiment to spread to the laboratory, the ventilation cabinet should be used near the source of the pollution, and the number of tables used in the former ventilator is less, only in the specially harmful and dangerous gas and the experiment of producing a large amount of heat. The ventilation cabinet only takes on the auxiliary function of the experimental platform.
    实验室装修在实验台上进行的实验逐渐转移到通风柜内,这就要求在通风柜里要有最适于设备使用的功能。特别是大多新建的实验室都要求有空调,因此在建筑的初步设计阶段就要将通风柜的使用台数纳入空调系统的计划。
    Laboratory decoration experiments on the experimental platform are gradually transferred to the fume hood, which requires the most suitable function in the fume hood. In particular, most of the newly built laboratories require air conditioning, so in the initial design stage of the building, the number of use tables of the ventilator should be included in the plan of the air conditioning system.
    由于通风柜在生化实验室中占有非常重要的位置,从改善实验室环境、改善劳动卫生条件,提高工作效率等方面考虑,通风柜的使用台数飞快地增加,随之而来的是通风管道、配管、配线、排风等都成为实验室建设的重要课题。
    The ventilation cabinet occupies a very important position in the biochemical laboratory, from improving laboratory environment, improve health conditions, improve work efficiency and other aspects, the number of ventilation cabinet quickly increased, followed by a ventilation pipe, piping, wiring and ventilation have become an important topic in the construction of laboratory.
