Abstract

The invention provides a waste incineration system and a high-efficiency incineration control method. The waste incineration system comprises a primary combustion chamber used for primary waste combustion. An exhaust gas outlet of the primary combustion chamber communicates with an exhaust gas inlet of a secondary combustion chamber through a first flue. An exhaust gas outlet of the secondary combustion chamber is connected with a spray tower used for spraying treatment on exhaust gas through a second flue. An outlet of the top end of the spray tower is connected with an exhaust gas purifyingsystem through a third flue. The waste incineration system can effectively control the waste incineration temperature, make use of flammable gas generated from incineration, meanwhile, controls the exhaust gas combustion temperature and the exhaust gas cooling rate to decompose dioxin and prevents resynthesis of dioxin to meet the treated waste emission standard. The high-efficiency incineration control method is high in intelligence degree, advanced, high in working efficiency, safe, reliable, energy-saving and friendly to environment.

Description

Background technique [0001] At present, the flue gas after incineration of waste incineration treatment equipment is directly discharged into the air. First, the heat and combustible gas in the incineration process are not well utilized, which is not conducive to energy saving; second, the combustion process is not well controlled. The dioxin in the flue gas is discharged according to the standard. Contents of the invention [0002] In order to overcome the deficiencies of existing waste incineration treatment equipment, the present invention provides an intelligent control method and device for waste incineration treatment equipment, which can effectively control the temperature of waste incineration and utilize the combustible gas produced by incineration, and simultaneously control the combustion temperature of tail gas and flue gas The cooling speed decomposes dioxins and prevents dioxins from resynthesizing, so as to meet the discharge standard requirements after garbag...
