Title: Reducing air pollution caused by traffic
Inventor: KEITH HENRY HOWARD
IPC: B01D47/06
Filed: 1995-06-30
Abstract: Part A: Reducing Air Pollution by Water Spray. Elevated sprinkler nozzles in groups of 3 are within their designated area activated at 3 discrete control levels created by area gas analysers depending on the severity of the measured pollution of preselected gases. To avoid a pollution build-up at approaches to traffic lights a combination of traffic light logic with gas analyser control logic is possible. Part B: Reducing Air Pollution by Suction into Rainwater Disposal Systems. The removal of the wetted pollutants into the sewer mains is assisted by negatively pressurizing the rainwater disposal systems as well as by water curtains behind electric exhaust fans. In cases of fan failures the maintenance of suction in the disposal system is safeguarded by louvers.
