Abstract
A seeder includes a housing defining a cavity, a housing gas inlet, and a seeder outlet. A sprayer is disposed within the cavity and includes a sprayer gas inlet configured to receive a gas, wherein the sprayer gas inlet is in fluid communication with the housing gas inlet. The sprayer also includes a sprayer liquid intake configured to be in fluid communication with the cavity to intake a liquid media from the cavity and a sprayer nozzle configured to be in fluid communication with the cavity above a liquid level. The sprayer is configured to combine the liquid media with the gas to spray a gas-liquid mixture through the sprayer nozzle and on to an interior spray surface of the housing.
Claims18
A seeder, comprising:
- a housing defining a cavity and including a housing gas inlet and a seeder outlet;
- a sprayer disposed within the cavity, including:
- a sprayer gas inlet configured to receive a gas, the sprayer gas inlet in fluid communication with the housing gas inlet;
- a sprayer liquid intake configured to be in fluid communication with the cavity to intake a liquid media from the cavity;
- and
- a sprayer nozzle configured to be in fluid communication with the cavity above a liquid level, wherein the sprayer is configured to combine the liquid media with the gas to spray a gas-liquid mixture through the sprayer nozzle and on to an interior spray surface of the housing,
- wherein the seeder is configured to eject the aerosolized portion of the liquid media through the seeder outlet and to cause a liquid portion of the gas-liquid mixture that is sprayed on the interior spray surface to drip from the interior spray surface without dripping onto the sprayer nozzle.
A method for seeding an airflow with liquid particles, comprising:
- aspirating liquid stored within a housing with gas flowing through a nozzle;
- rotationally swirling the gas-liquid mixture;
- spraying the gas-liquid mixture against an internal surface of the housing;
- aerosolizing some of the liquid in the gas-liquid mixture;
- and
- exhausting the aerosolized liquid from the housing.
A seeder, comprising:
- a housing defining a cavity and having at least one opening;
- and
- a nozzle positioned within the cavity having an outlet, a gas inlet and a liquid inlet, the liquid inlet being positioned within the cavity, the nozzle being configured to draw liquid into the nozzle via the liquid inlet in response to gas flowing through the nozzle and to rotationally swirl the gas-liquid mixture and discharge the gas-liquid mixture into the cavity, the at least one opening being configured to exhaust aerosolized liquid from the housing.
