Equipment used for fly ash treatment

Abstract

The invention provides equipment used for fly ash treatment and belongs to the technical field of fly ash treatment. The equipment comprises a furnace body, a furnace cover, a crucible, a smoke treatment mechanism and a crucible drive mechanism. The top of the furnace cover is provided with a fly ash feeding opening and a smoke exhausting opening. The smoke exhausting opening is connected with thesmoke treatment mechanism. Ignition devices are arranged on the two sides of the middle portion of the furnace body. The top of the crucible abuts against the inner wall of the furnace body. The crucible drive mechanism is connected with the crucible and drives the crucible to rotate. A first discharging opening is formed in the bottom of the crucible. A second discharging opening is formed in the bottom of the furnace body. The end portion of the first discharging opening is inserted into the second discharging opening, and thus the first discharging opening and the second discharging opening communicate. According to the equipment, fly ash can be subjected to fusion treatment, and recycling of resources is achieved. By the adoption of the design of the crucible drive mechanism, the crucible can rotate intermittently, the ignition devices can heat and ignite fly ash in the crucible, heating time and combustion time of the fly ash are shortened, and the fusion efficiency of the fly ash is improved.

Description

technical field [0001] The invention belongs to the technical field of fly ash treatment, and in particular relates to a device for fly ash treatment. Background technique [0002] With the rapid development of China's economy, people's living standards and consumption ability are also continuously improved, and more and more daily necessities are purchased. Therefore, the per capita domestic waste generation is also increasing, and the domestic waste disposal volume is increasing. bigger. In the process of processing people's daily garbage, waste incineration for power generation and waste pyrolysis gasification are important technologies for waste treatment, and both waste incineration and waste pyrolysis gasification processes will produce a large amount of fly ash, which contains Pollutants such as dioxins and heavy metals with high concentrations, the toxicity of dioxins and heavy metals pose a threat to the environment and belong to hazardous waste. [0003] The meth...

Problems solved by technology

[0004] At present, fuel (coal powder) is used for melting and solidification to heat the fly ash to a high temperature of about 1400°C, so that the fly ash is melted into a glass body, but during this process, the fuel combustion produces a large amount of smoke, which contains unmelted Fly ash, which will affect the treatment and purification of flue gas, needs to be filtered in advance

At the same time, it takes a lot of time to heat up and burn the fly ash, and the combustion efficiency is low
