Abstract
A detection device comprises a cyclone-type collection part for collecting particles contained in a gas into a collection liquid with a swirling airflow, a detection part for detecting the particles collected by the cyclone-type collection part; and a cleaning part for cleaning the cyclone-type collection part with a cleaning liquid. The cleaning part cleans the cyclone-type collection part by swirling the cleaning liquid with the swirling airflow generated in the cyclone-type collection part.
Claims10
A detection device, comprising:
- a cyclone-type collection part for collecting particles contained in a gas into a collection liquid using a swirling airflow;
- a detection part for detecting the particles collected by the cyclone-type collection part;
- a cleaning part for cleaning the cyclone-type collection part using a cleaning liquid;
- and
- a controller configured to change a speed of the swirling airflow during a cleaning of the cyclone-type collection part, wherein:
- the cleaning part swirls the cleaning liquid with the swirling airflow generated in the cyclone-type collection part to clean the cyclone-type collection part,
- the cyclone-type collection part comprises a cyclone for receiving the collection liquid and a tube attached to the cyclone at a first side of the cyclone,
- the cyclone-type collection part includes a gas introduction port for introducing the gas to the cyclone and a gas discharge port for discharging the gas from the cyclone at the first side of the cyclone, the gas introduction port being attached to the tube,
- the cyclone further comprises a cleaning liquid introduction port for introducing the cleaning liquids at the first side and a liquid discharge port for discharging the collection liquid in the cyclone at a second side opposite to the first side with respect to the cyclone, the cleaning liquid introduction port being attached to the tube at a different position of the tube than the gas introduction port, and
- a distance between the cleaning liquid introduction port and the bottom part of the cyclone is greater than a distance between the gas introduction port and the bottom part of the cyclone.
