摘要： Air cleaning apparatus includes: a tank; a detergent inlet into the tank; a water inlet into the tank; an air inlet into the tank; at least one sparger in fluid communication with the air inlet; a vacuum pump; an air outlet in fluid communication with the vacuum pump; and at least one valve between the air outlet and the vacuum pump and configured to control flow of fluids through the air outlet. The apparatus is configured to conduct a method to pull polluted external air into the tank through the air inlet to the at least one sparger, sparge bubbles of the polluted air from the at least one sparger into a mixture of the water and the nonfoaming detergent in the tank, remove pollutants from the air as it rises through the mixture, extract clean air from the mixture into a cavity in the tank above the mixture and extract the clean air from the cavity through the air outlet to an external environment with the vacuum pump.
