Fly ash melting process for garbage power plant and plasma torch for heating fly ash

Abstract

The invention discloses a garbage power plant fly ash melting process and a plasma torch for heating the garbage power plant fly ash. The plasma torch comprises an operation table, a feeding device is arranged on the operation table, a mixing device located on the operation table is arranged below the feeding device, a rolling device is rotationally arranged on the operation table, and a crushing device for crushing is arranged on one side of the rolling device; a rotary conveying device located on the operation table is arranged below the crushing device, a drying device located above the conveying device is fixed to the operation table, a collecting device is arranged on the drying device and connected with the mixing device, and a storage device is rotationally arranged on the operation table. Materials of the feeding device enter the material mixing device to be evenly stirred, the cleaning brush can clean the inner wall of the material mixing barrel, the drying device is used for drying the granular materials, generated fly ash is screened through the collecting device and enters the material mixing device to be circularly processed, and other fly ash is recycled for waste utilization. The resource utilization rate can be improved, and secondary pollution is thoroughly solved.

Description

technical field [0001] The invention relates to the field of domestic garbage treatment, in particular to a melting process of fly ash of a garbage power plant and a plasma torch for heating thereof. Background technique [0002] With the deepening of my country's industrialization, informatization and urbanization and the rapid development of modern society, environmental pollution is becoming more and more serious. Faced with the problem of domestic waste disposal, methods such as sanitary landfill, biocomposting and incineration are usually used to deal with domestic waste. Garbage, but these treatment methods have various problems such as incomplete treatment, secondary pollution and serious waste of resources, which makes people have to seek more effective treatment methods to properly handle and effectively utilize waste. At present, the main methods of fly ash treatment include plasma melting, sintering, cement kiln co-processing and so on. [0003] Although plasma me...

AI Technical Summary

Problems solved by technology

[0003] Although plasma melting is currently the most advanced fly ash treatment method, there are still many deficiencies in the ion melting technology for fly ash treatment. Fly ash directly enters the treatment equipment, and under the impact of the plasma jet in the treatment furnace, it will Causes the secondary fly ash problem in the follow-up exhaust gas; the flue gas generated in the system cannot be treated friendly, and the flue gas emitted during the raw material melting process is mainly CO2, SO2, H2O, NaCl, KCl and other substances are directly discharged, resulting in a waste of resources , easy to form secondary fly ash
