Embodiment Construction

[0020] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0021] The present invention is a system for co-processing garbage fly ash and leachate, as attached figure 2 As shown, it includes garbage storage bin 1, leachate purification device 2, garbage incineration boiler 3, dust collector 4, flue gas purification device 5, chimney 6, fly ash melting furnace 7, burner 8, fly ash storage bin 9, wind Powder mixer 10 and slag pool 11. The fly ash melting furnace 7 is composed of two heat-insulating cylindrical containers, one is a melting chamber 71 and the other is an evaporation chamber 72, and the bottoms of the melting chamber 71 and the evaporation chamber 72 are connected by a flue. The outlet of the garbage storage bin 1 is respectively connected to the inlet of the leachate purification device 2 and the inlet of the garbage incineration boiler 3, the outlet of the garbage incinera...

Abstract

The invention provides a system for cooperatively treating garbage fly ash and leachate. The system comprises a garbage incineration system and is characterized by further comprising a fly ash fusiondevice, wherein the fly ash melting device comprises a fly ash melting furnace and a burner for heating the fly ash melting furnace, an inlet of the fly ash melting furnace is connected with an outletof a dust remover and a concentrated water outlet of a leachate purification device, and an outlet of the fly ash melting furnace is connected with an inlet of a garbage incineration boiler. On one hand, the garbage fly ash can be fused and converted into a glassy state, so that the garbage fly ash is changed from hazardous waste to general solid waste; and on the other hand, leachate generated by garbage storage can be treated, and flue gas generated by fusing fly ash can also be discharged up to the standard. The waste treatment efficiency is improved, the influences caused on stable combustion of the incinerator when concentrated water directly enters the waste incineration system are effectively avoided, the treatment effect is more thorough, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a system for co-processing garbage fly ash and leachate, which belongs to the field of hazardous waste treatment. Background technique [0002] Waste incineration can achieve the goals of waste reduction, recycling, and harmless treatment, and is the preferred method of waste disposal. Currently the most widely used waste incineration process is attached figure 1 As shown: the garbage in the garbage storage bin 21 enters the garbage incineration boiler 23 for combustion, and the flue gas generated after combustion passes through the dust collector 24 and the flue gas purification device 25 to remove pollutants in the flue gas, and is discharged through the chimney 26 after reaching the standard. [0003] After the domestic waste is incinerated, incineration fly ash equivalent to 2% to 5% of the mass of the original waste will be produced, which will be captured by the dust collector 24 . The fly ash contains more volatile hea...
