Title:
AIR INTAKE AND EXHAUST SYSTEM FOR RADIOPHARMACEUTICAL PACKAGING HOT CELL
Document Type and Number:
WIPO Patent Application WO/2023/045570
Kind Code:
A1
Abstract:
An air intake and exhaust system for a radiopharmaceutical packaging hot cell, comprising an air intake pipe (13) and an air exhaust pipe (14) that are located at the top of a hot cell (1). The hot cell (1) comprises a box body (11) and an inner container (12) arranged in the box body (11). The bottom of the air intake pipe (13) is communicated with the inner container (12). A ventilation opening (121) is formed on the inner container (12). A ventilation pipe (15) is provided in the box body (11). The bottom end of the ventilation pipe (15) is communicated with the ventilation opening (121), and the top end of the ventilation pipe (15) passes through the bottom of the air exhaust pipe (14) and is in sealing fit with the bottom of the air exhaust pipe (14). An air intake fan (131) is connected to the air intake pipe (13), and a primary filter (132) and a high-efficiency filter (131) are provided on the air intake pipe (13). An air exhaust fan (141) is provided on the air exhaust pipe (14), and an activated carbon filter (142) is provided on the air exhaust pipe (14). The top end of the ventilation pipe (15) is provided with a centrifugal filter (2), and the centrifugal filter (2) is located in the air exhaust pipe (14). The centrifugal filter (2) is provided in the air exhaust pipe (14), and radioactive substances are further filtered by means of rotation of the centrifugal filter (2), so that the emission of radioactive substances is reduced.
