Problems solved by technology

However, the traditional fly ash sintering adopts the rotary kiln combustion device heated by coal, gas, and fuel oil, which generates high-temperature flue gas to heat the discharge material, and is affected by incomplete combustion. During the sintering process, due to uneven heating, the sintering recovery rate Low, long sintering time period, high energy consumption, unstable product quality, uneven sintering

Abstract

The invention discloses a device for microwave sintering of ceramic particles by rotary garbage incineration fly ash and an operation method. The garbage incineration fly ash is mixed with pyrite sintering slag for pelletizing to enter a rotary furnace body with microwave coupling agent powder for microwave sintering; a rotary reaction furnace is inclined, so that the ceramic particles are heated by microwaves in rolling mixing; the sintered ceramic particle clinkers are separated from a microwave coupling agent; the separated microwave coupling agent serves as a raw material for recycling; the innovation increases the utilization rate of the microwave coupling agent; meanwhile, the device is simple in preparation process and full in energy utilization, solves the problem of generating a lot of harmful smoke needing to be purified in a traditional sintering technology, promotes the industrial process of incineration fly ash microwave sintering, and in particular, is suitable for the fly ash harmless treatment with sintering of the ceramic particles by the incineration fly ash as the purpose.

Description

technical field [0001] The invention relates to a method for treating waste incineration fly ash, in particular to a device and an operating method for a rotary type waste incineration fly ash microwave sintering ceramsite. Background technique [0002] Waste incineration fly ash is rich in dioxins and heavy metals and other hazards. Sintering treatment can decompose dioxins in fly ash, solidify most of the heavy metals, and prepare ceramsite. However, traditional fly ash sintering uses a rotary kiln combustion device heated by coal, gas, and fuel oil, which generates high-temperature flue gas to heat the output material, and is affected by incomplete combustion. During the sintering process, due to uneven heating, the sintering recovery rate Low sintering time, high energy consumption, unstable product quality and uneven sintering. [0003] Microwave heating has been widely used in recent years due to its advantages of fast heating speed, strong selectivity, and uniform he...
