Negative pressure purification system for transfer cabin
The invention relates to a negative pressure purification system for a transfer cabin. The negative pressure purification system involves a transfer cabin main body, an air inlet HEPA filter, an air outlet HEPA filter and a fan, wherein the air inlet HEPA filter and the air outlet HEPA filter are arranged at an air inlet and an air outlet of the transfer cabin main body respectively; and the system is characterized in that the system further involves a fan pressure sensor and a fan detection control module which are used for detecting and controlling operation of the fan, and two HEPA filter pressure sensors which are used for detecting the air inlet HEPA filter and the air outlet HEPA filter, the fan pressure sensor is used for detecting pressure inside and outside the cabin, and the fandetection control module adjusts the rotating speed of the fan according to the pressure difference between the interior and the exterior of the cabin, so that the negative pressure target control of-20 Pa - -30 Pa is achieved; and the two HEPA filter pressure sensors are used for detecting the front and back pressure of the two HEPA filters. The purification system is more efficient, energy-saving and comfortable, can guarantee that patients are effectively isolated in the transportation process, protects medical workers, and prevents infection sources from being diffused.
本发明涉及一种转运舱负压净化系统，包括转运舱主体，分别设置在转运舱主体进风口的进风口和出风口的进风口HEPA过滤器和出风口HEPA过滤器以及风机，其特征在于，还包括用于检测和控制风机运行的风机压力传感器和风机检测控制模块以及用于检测进风口HEPA过滤器和出风口HEPA过滤器的两个HEPA过滤器压力传感器，风机压力传感器用于检测舱内外压力，风机检测控制模块根据舱内外压差调节风机转速，从而实现‑20Pa～‑30Pa的负压控制目标；两个HEPA过滤器压力传感器分别用于检测两个HEPA过滤器前后的压力。本发明的净化系统更加高效节能且舒适，可保证在运输过程中有效隔离患者，保护医护人员，防止传染源扩散。
