Математическое описание процесса охлаждения генераторного газа в установке утилизации отходов жизнедеятельности

Abstract

In the paper we consider a problem of accumulation of solid domestic and industrial wastes and ground its relevance. The method of solving the problem consists in utilizing the waste by means of mixed gasification. A significant drawback of the method is the secondary formation of highly toxic substances in the gaseous product of this process. To solve this problem a method of quenching the generating gas by injecting liquid by centrifugal dispersing nozzles into its flow is proposed. The article contains the mathematical description of the process of cooling of generating gas in the installation for utilization of biowaste products. On the basis of the classical theory of gas dynamics the mathematical relationships describing gas and dispersed phase and interphase interaction in the process of cooling are obtained.
