  • 實驗室通風對實驗室裝修有哪些作用

    實驗室通風是實驗室設計的關鍵,通風櫃與排風體係設計榴莲视频app下载地址都知道,在化學試驗過程中,經常會發生各種難聞的,有腐蝕性的、有毒的或易爆的氣體。這些有害氣體如不及時掃除室外,就要形成室內空氣汙染,影響試驗人員的健康與安全;影響儀器設備的精度和運用壽命,因而,試驗室通風是試驗室設計中不行短少的一個組成部分。
    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.

    為了使試驗室作業人員不吸入或咽入一些有毒的、可致病的或毒性不明的化學物質和有機體,為阻撓一些蒸氣、氣體和微粒吸入,汙染物質須用通風櫃、通風罩、部分排風的辦法除去。

    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.
    化學試驗室的通風辦法有兩種,即部分排風和全室通風。部分排風是在有害物質發生後立即就近排出,這種辦法能以較少的風量排走大量的有害物質,能量省而作用好,是改進現有試驗室條件可行和經濟的辦法,也也許是適應新試驗室通風建造的佳辦法。關於有些試驗不能選用部分排風,或部分排風滿意不了排風請求時,選用全室通風。
    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.
    因為體係較大,風量不易平衡,雖然每個試驗室通風櫃上都裝有調節閥,但運用不方便,並且也不容易到達預定的作用。假如體係風管損壞需要維修時,那麽整個體係的試驗室通風櫃就無法運用。所以,本來選用集中式體係的試驗室,先後都改為用分散式體係。
    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.
