Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ash processing machinery, and in particular to a slag discharger structure capable of preventing ash backflow. Background Art
[0002] In people's daily life, a lot of garbage is inevitably generated. If these garbage are not effectively treated, it will greatly affect people's living environment and even threaten people's health. At present, incineration is one of the main ways to deal with garbage, but in the process of incinerating garbage, in addition to causing secondary environmental pollution, it will also cause waste of resources and energy. Therefore, in garbage disposal, garbage incineration power generation can be adopted.
[0003] Waste incineration produces a lot of ash, and high-temperature ash usually needs to be washed. The purpose of washing the high-temperature ash produced by waste incineration is mainly to remove soluble salts, especially chloride salts, and reduce the content of heavy metals. The washing process can effectively reduce the chlorine element in fly ash to below 1%, while controlling the water content in fly ash within 30%, which helps to reduce the risk of environmental pollution caused by fly ash and create conditions for the resource utilization of fly ash. In addition, the washed fly ash can be used as a raw material for cement production, and can be recycled and harmless through the coordinated disposal of cement kilns.
[0004] In actual use, the existing slag discharger will have ash reflux into the water replenishment tank along with the water flow, causing ash deposition in the water replenishment tank, while affecting the normal use of the float valve and the normal water replenishment of the water replenishment tank.
