    • A ventilation system for a glove box (1) comprising first (4,5) and second (10,14) extract flow lines connected in parallel between a common outlet (15) from the box and a suction pump (6). Each extract line includes a vortex amplifier (3,9) and a filter (11,12). The vortex amplifiers are chosen such that under normal operating conditions the required depression within the box is maintained by flow along the first of the extract lines and a reverse flow from the vortex amplifier in the second extract line passes through the filter in that line and exits through the first extract line without passing into the glove box. The second extract line functions as an emergency extract capability in the event of a breach of the glove box and the reverse flow keeps the filter in the line in a clean and usable condition.
    • 一种用于手套箱(1)的通风系统,包括第一(4,5)和第二(10,14)提取物流线,其平行地连接在来自所述箱的公共出口(15)和抽吸泵(6)之间。 每个提取线包括涡流放大器(3,9)和过滤器(11,12)。 选择涡流放大器使得在正常操作条件下,通过沿着第一提取管线的流动来维持盒内所需的凹陷,并且来自第二提取管线中的涡流放大器的反向流动通过该管线中的过滤器并且退出 通过第一条提取线,而不会进入手套箱。 第二提取线作为在手套箱破裂的情况下的紧急提取能力,并且反向流将过滤器保持在清洁和可用的状态。

    • The invention relates to a circuit for ventilating and filtering the medium contained in a confinement enclosure (10) and also a method for sterilizing such an enclosure and its supply and discharge filters.An emergency or standby circuit is associated with the circuit ensuring ventilation and filtration under normal operating conditions and which comprises a supply pipe (20) and a discharge pipe (12), equipped with a suction fan (14). The said emergency circuit comprises the same pipes used in the opposite direction under the action of a suction fan (28) located in supply pipe (20), whereby said fan (28) can be automatically controlled by a pressostat (30). Sterilization is performed chemically, using a sterilizer which is connected to the supply duct between a valve and the supply filters disposed downstream of the valve. The sterilizer delivers a sterilizing agent which passes successively through the supply filters, the enclosure and the discharge filters. Once sterilization has been performed, the ventilating circuit is started up, so as to sweep away the sterilizing agent.Application to biological or nuclear experimentation enclosures.
    • 本发明涉及一种用于通风和过滤包含在限制外壳(10)中的介质的电路,以及用于对这种外壳及其供应和排出过滤器进行消毒的方法。 紧急或备用电路与在正常运行条件下确保通风和过滤的电路相关联,并且包括具有抽吸风扇(14)的供应管(20)和排放管(12)。 所述紧急回路包括在位于供应管道(20)内的吸风机(28)的作用下沿相反方向使用的相同的管道,由此所述风扇(28)可以由压力调节器(30)自动控制。 使用消毒器进行灭菌,灭菌器在阀和位于阀下游的供给过滤器之间连接到供应管道。 灭菌器提供灭菌剂,其连续通过供应过滤器,外壳和放电过滤器。 一旦进行灭菌,启动通风回路,以便消除灭菌剂。 应用于生物或核实验室。
