Abstract

The invention discloses a combined cyclone boiler combustion device and method for flying ash fusion. The device is composed of a horizontal cyclone combustion chamber, a vertical cyclone combustion chamber and a water channel, wherein the outlet of the horizontal cyclone combustion chamber is connected with the inlet of the vertical cyclone combustion chamber; after pulverized coal conveying air is mixed with pulverized coal, the mixture is injected into the horizontal cyclone combustion chamber from the boiler head of the horizontal cyclone combustion chamber; after primary air is mixed with the flying ash, the mixture tangentially enters the horizontal cyclone combustion chamber from the lower reaches of the fuel inlet, so that the temperature of the front end of the horizontal cyclone combustion chamber can not be lowered, and the front-end area of the horizontal cyclone combustion chamber can be kept at high temperature, which is favorable for the pulverized coal to stably catch fire and burn; secondary air tangentially enters the vertical cyclone combustion chamber; and the rotation direction of the secondary air is same with the rotation direction of the primary wind. According to the device and the method, flying ashes of different particle diameters can be guaranteed to fully fuse, and the integral fusion collection efficiency of the flying ash can be improved.

Description

technical field [0001] The invention relates to a device and method for melting and processing fly ash, belonging to the technical field of safe processing of fly ash. Background technique [0002] With the rapid development of the national economy, the urbanization process is accelerating, and the amount of domestic waste is increasing sharply. Waste incineration power generation can better achieve the goals of waste reduction, resource utilization, and harmless treatment. In developed countries and my country widely promoted and applied. However, the fly ash produced by the incineration of domestic waste contains high concentrations of dioxins and a large amount of heavy metals and other harmful substances, and has a high leaching rate, which is a hazardous waste. If it is discharged directly without treatment, it will pollute the soil and groundwater. It is bound to cause serious secondary pollution. [0003] At present, cement solidification landfill or high-temperature...
