检测门
摘要：
本发明涉及检测门（100），用于检测个体（108）或者对象所携带的物质，所述检测门（100）包括：两个侧面直立部分（102、104），彼此面对并且在二者之间限定出用于所述个体（108）或者所述对象的通道（106）；吹气装置（110），安装在所述直立部分中的一个直立部分（102）所具有的吹气室（122）中，并且所述吹气装置（110）适合于将包含在所述吹气室（122）中的空气朝向另一个直立部分（104）吹送；排气装置（118），安装在另一个直立部分（104）所具有的排气室（124）中，并且所述排气装置（118）能够吸入如此吹送的空气；检测设备（120），设置在所述通道（106）的下游，并且能够检测在如此被吹送的空气中的所述物质的存在；以及转移管（126），其端部之一出现在所述吹气室（122）中，其另一个端部出现在所述排气室（124）中；所述吹气装置（110）和所述排气装置（118）使得在所述个体（108）或者对象通过所述通道（106）期间，同样体积的空气具有至少两次行进穿过所述通道（106）的时间。
摘要（英）：

The invention relates to a detection gate (100) for detecting substances carried by an individual (108) or an object, the detection gate (100) comprising: two lateral uprights (102, 104) facing one another and defining a passage (106) therebetween for said individual (108) or said object; blowing means (110) installed in a blowing chamber (122) which one of the uprights (102) comprises, and which are adapted to exhaust the air contained in said blowing chamber (122) towards the other upright (104); exhaust means (118) installed in an exhaust chamber (124) which the other upright comprises (104), which are suitable for exhausting the air thus blown; a detection device (120) arranged upstream from the passage (106) and adapted to detect the presence of said substances in the air thus blown; and a transfer line (126) which, via one of the ends thereof, leads into the blowing chamber (122); and, via the other end thereof, into the exhaust chamber (124). The blowing means (110) and the exhaust means (118) being such that a single volume of air has time to pass through the passage (106) at least twice during the time that said individual (108) or said object is present in said passage (106).
