FIELD: technological processes.
SUBSTANCE: method of surface concentration regulation consists in the fact that unrefined spent gases (SG) from SG source are divided into two flows, the first flow is directed in units of neutralizer, where they are purified from hazardous substances, and the second flow is directed to bypass channel, flow rate of spent gases is controlled in flows, and both flows are exhausted in environment, additionally, prior to exhaustion of the first and second flows in environment, flows are combined, parameters of spent gases are measured in combined flow, measured values of parameters are sent to comparison unit, where with the help of SG parameters surface concentration is calculated and calculated value of surface concentration is sent to corrector, speed and direction of incoming air flow are measured and sent to corrector, where value of calculated surface concentration is corrected by values of measured speed and direction of incoming air flow, corrected value of surface concentration is sent to comparison unit, where value of corrected surface concentration is compared to value of standard surface concentration, and if value of corrected surface concentration exceeds value of standard surface concentration, the flow rate of spent gases is increased in the first flow and flow rate of spent gases in the second flow is reduced, and if value of standard surface concentration exceeds value of corrected one, the flow rate of spent gases is reduced in the first flow and flow rate of spent gases in the second flow is increased. System of surface concentration regulation is given.
EFFECT: improvement of ecological condition of area and conditions of operation of spent gases source of vehicles with internal combustion engine.
