ABSTRACT:
An exhaust gases and particulate capture system comprises an aspirator unit and a secondary stack mounted in fluid cooperation with a large water tank. Exhaust gases, along with entrapped particulates from the combustion process, are removed from a smokestack and are introduced into the aspirator unit and mixed with water from the tank. The gases and particulates are blended with the water in the mixing chamber of the aspirator which churns the gases, particulates and water into a very turbulent condition. The resulting mixture is discharged from the aspirator through an entrainment nozzle into the water tank. The design of the exit end of the entrainment nozzle effects a sweeping motion to the mixture being discharged ensuring that the mixture is discharged over the entire width of the tank holding the water. The exhaust gases and entrapped particulates are cooled and condensed in the water tank and the particulates settle down to the bottom of the tank. A positive gas pressure over the top of the water in the tank keep the exhaust gases from escaping to the atmosphere. Baffles are provided between the aspirator unit and the secondary stack to quiet the water flowing into the region of the secondary stack. The exhaust gases leaving the secondary stack to the outside atmosphere are free from pollutants and particulate matter.
