  • 实验室通风对实验室装修有哪些作用
    来源:http://www.jnyhrs.com 浏览: 发布日期:2017-06-20
    实验室通风是实验室设计的关键,通风柜与排风体系设计我们都知道,在化学试验过程中,经常会发生各种难闻的,有腐蚀性的、有毒的或易爆的气体。这些有害气体如不及时扫除室外,就要形成室内空气污染,影响试验人员的健康与安全;影响仪器设备的精度和运用寿命,因而,试验室通风是试验室设计中不行短少的一个组成部分。
    Laboratory ventilation is the key to the design of the laboratory, ventilation cabinet and exhaust system design as we all know, in the chemical test process, often have various bad gas, corrosive, toxic or explosive. These harmful gases such as not timely cleaning will be outdoor, indoor air pollution, health and safety of testing personnel; influence of equipment precision and service life, therefore, laboratory ventilation is a part of the test chamber design indispensable.

    为了使试验室作业人员不吸入或咽入一些有毒的、可致病的或毒性不明的化学物质和有机体,为阻挠一些蒸气、气体和微粒吸入,污染物质须用通风柜、通风罩、部分排风的办法除去。

    In order to make the laboratory workers not inhaled or swallowed some poisonous and can cause disease or toxicity of unknown chemical substances and organisms, to block some steam, gases and particles are inhaled, pollutants must use the ventilation cabinet, ventilation hood, exhaust fan to remove part.
    化学试验室的通风办法有两种,即部分排风和全室通风。部分排风是在有害物质发生后立即就近排出,这种办法能以较少的风量排走大量的有害物质,能量省而作用好,是改进现有试验室条件可行和经济的办法,也也许是适应新试验室通风建造的佳办法。关于有些试验不能选用部分排风,或部分排风满意不了排风请求时,选用全室通风。
    There are two types of ventilation in chemistry laboratory, that is, partial ventilation and whole room ventilation. In the part of exhaust is harmful substances occur immediately after the drains, this way with less air discharged large quantities of harmful substances, energy, and the effect is good, is to improve the existing laboratory conditions feasible and economic way, also may be the best way to adapt to the new lab building ventilation. As for some tests, partial ventilation can not be used, or partial ventilation can not satisfy the demand of exhaust ventilation.
    因为体系较大,风量不易平衡,虽然每个试验室通风柜上都装有调节阀,但运用不方便,并且也不容易到达预定的作用。假如体系风管损坏需要维修时,那么整个体系的试验室通风柜就无法运用。所以,本来选用集中式体系的试验室,先后都改为用分散式体系。
    Because the system is larger, the air flow is not easy to balance, although each laboratory ventilation cabinet is equipped with regulating valve, but the use of inconvenience, and it is not easy to achieve the intended role. If the duct of the system is damaged and needs to be repaired, then the test cabinet of the whole system can not be used. Therefore, the laboratory which used the centralized system has been changed to decentralized system.
