Abstract
A method for collecting particles or gaseous chemicals is provided. The method includes providing liquid to a tube of a droplet generator, heating, with a heater of the droplet generator, the tube to provide vapor to a gas flow channel inside the tube, passing a gas flow containing the particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals, and passing the droplets including the particles or gaseous chemicals to a wall of a collecting device such that the droplets including the particles or gaseous chemicals hit the wall. The temperature inside the gas flow channel is higher than a temperature inside the collecting device.
Claims20
A method for collecting particles or gaseous chemicals, the method comprising:
- providing liquid to a tube of a droplet generator;
- heating, with a heater of the droplet generator, the tube to provide vapor to a gas flow channel inside the tube;
- passing a gas flow containing the particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals;
- and
- passing the droplets including the particles or gaseous chemicals to a wall of a collecting device such that the droplets including the particles or gaseous chemicals hit the wall,
- wherein a temperature inside the gas flow channel is higher than a temperature inside the collecting device.
A system for collecting particles or gaseous chemicals, the system comprising:
- a pump;
- a droplet generator comprising:
- a chamber;
- a tube containing liquid and extending through the chamber;
- a gas flow channel inside the tube;
- and
- a heater configured to heat the liquid contained in the tube to provide vapor to a gas flow channel inside the tube;
- and
- a collecting device comprising a wall,
- wherein the pump is configured to:
- pass a gas flow containing particles or gaseous chemicals through the gas flow channel inside the tube to obtain droplets including the particles or gaseous chemicals;
- and
- pass the droplets including the particles or gaseous chemicals to the wall of the collecting device such that the generated droplets including the particles or gaseous chemicals hit the wall.
