Title
(EN) FINE PARTICLE ANALYSIS DEVICE, FINE PARTICLE ANALYSIS SYSTEM, AND CLEANING METHOD
(ZH) 微粒分析装置、微粒分析系统以及清洗方法
Abstract
(EN)
Provided is a fine particle analysis device, and to clean the inside thereof without stopping or disassembling the fine particle analysis device, the following are provided: a cyclone dust collectiondevice (14); a primary filter (16) that is connected downstream of the cyclone dust collection device (14) and that is heated; a gas analysis device (31) that is connected to the primary filter (16);a gas piping section that connects the cyclone dust collection device (14) and the gas analysis device (31), and that has disposed therein the primary filter (16); and a cleaning gas introduction device (21) that introduces a cleaning gas downstream of the primary filter (16) in the gas piping section and/or to the cyclone dust collection device (14). The present invention is characterized in thatduring a cleaning mode in which at least the primary filter (16) is cleaned, the flow rate of the cleaning gas that is introduced from the cleaning gas introduction device (21) increases so as to begreater than the flow rate during an analysis mode in which fine particles are analyzed by the gas analysis device (31).
