Abstract
An exhaust gas cooling and particulate scrubbing system for automobiles includes a first stage intercooler for initial, indirect cooling of the exhaust gas and a direct exhaust gas cooling and scrubbing device preferably positioned downstream in the exhaust system therefrom. The intercooler is designed to provide circulation of a liquid cooling medium by convection and has airflow ducts positioned within a surrounding jacket oriented to permit air to move therethrough during movement of the automobile. The a direct exhaust gas cooling and scrubbing device passes the exhaust gas through a liquid cooling medium whereby the exhaust gas is cooled in an effort to trap suspended particulates in the liquid cooling medium.
Claims30
In an automotive exhaust system, the improvement comprising a direct exhaust gas cooling and scrubbing device comprising:
- a body defining a chamber and a passage for directing exhaust gas to the chamber;
- a liquid cooling medium held within the chamber and operable to be in direct contact with exhaust gas;
- and
- a sparger including a gas-diffusing wall having a plurality of holes therein,
- said sparger including a removable gas-diffusing cartridge mounted in the body and overlying the wall, said cartridge being configured and oriented to receive and pass therethrough exhaust gas exiting the holes of the wall,
- said wall and removable cartridge being submerged in the liquid cooling medium so as to cooperatively diffuse the exhaust gas into the liquid cooling medium.
A conditioning device for conditioning ambient air comprising:
- a body defining a chamber, said body including an inlet and exit and a passage fluidly connected to the inlet and exit for directing a flow of air into the chamber;
- a liquid cooling medium primarily consisting of water,
- said liquid cooling medium being held within the chamber and operable to be in direct contact with air;
- a sparger positioned within the body for dispersing and directing the flow of air into the liquid medium,
- said sparger including an air-diffusing wall having a plurality of holes therein,
- said sparger including a removable air-diffusing cartridge mounted in the body and overlying the wall, with air being configured to pass through the wall and cartridge,
- said wall and removable cartridge submerged in the liquid cooling medium so as to cooperatively diffuse the air within the liquid cooling medium;
- and
- a blower for pumping air into the chamber for passage through the liquid cooling medium in direct contact with the liquid cooling medium.
In an automotive exhaust system, the improvement comprising a direct exhaust gas cooling and scrubbing device comprising:
- a body defining a chamber for holding liquid cooling medium, a chamber gas inlet for directing exhaust gas to the chamber, and a chamber gas outlet for directing exhaust gas out of the chamber;
- said body defining a refillable reservoir for holding liquid cooling medium,
- said body defining a passage that fluidly connects the chamber and reservoir, with liquid cooling medium being configured to flow through the passage, and
- a flow regulating device mounted to said body and operatively positioned between the reservoir and the chamber for adjusting a flow of liquid cooling medium through the passage from the reservoir to the chamber, said flow regulating device including a shiftable element for selectively restricting the flow of liquid cooling medium from the reservoir to the chamber,
- said chamber and reservoir being fluidly connected between the inlet and outlet in a non-series arrangement so that exhaust gas is permitted to flow substantially only through the chamber.
