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 an operating method of a rotary waste incineration fly ash microwave sintering ceramsite. According to the method, waste incineration fly ash and pyrite cinder are mixed and granulated, the granulated waste incineration fly ash and pyrite cinder and microwave coupling agent powder enter a rotary furnace body together to be subjected to microwave sintering, by obliquely arranging a rotary reaction furnace, the ceramsite is subjected to microwave heating while rolling and mixing are carried out, the ceramsite clinker is separated from the microwave coupling agent when thesintering is carried out, and the separated microwave coupling agent is used as a raw material to be returned and reused; the utilization rate of the microwave coupling agent is improved by the innovation, meanwhile, the preparation process is simple, and the energy is fully utilized; the problem that a large amount of harmful flue gas needs to be purified in an traditional sintering technology is solved, the industrialization process of incineration fly ash microwave sintering is promoted, and the method is particularly suitable for the fly ash harmless treatment which is taken incinerationfly ash ceramsite as a purpose..

Description

[0001] The application of the present invention is a divisional application of the parent application "A device and operation method for microwave sintering ceramsite with rotary waste incineration fly ash". The application date of the parent application is August 5, 2016. The application of the parent application The number is 2016106431753. technical field [0002] The invention relates to a method for treating waste incineration fly ash, in particular to a method for operating rotary waste incineration fly ash microwave sintered ceramsite. Background technique [0003] Waste incineration fly ash is rich in harmful substances such as dioxins and heavy metals. Sintering treatment can decompose dioxins in fly ash, solidify most of the heavy metals, and prepare ceramsite. 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 affecte...
