Fly Ash Plasma Treatment Plant

Abstract

The invention discloses a fly ash plasma treatment device, which relates to the technical field of harmless treatment of solid waste, and comprises from bottom to top: a melting combustion chamber, an oxygen storage chamber, a feeding chamber and an air outlet extending chamber; the melting combustion chamber A plasma torch generator is installed obliquely on the side wall, and a slag outlet is provided at the bottom of the melting combustion chamber; an auxiliary gas inlet channel is installed obliquely on the side wall of the oxygen storage chamber, and a controllable valve is connected to the auxiliary gas inlet channel; A feeding channel is installed obliquely on the side wall of the feeding chamber, and the inner wall of the feeding channel is provided with a spray device. On the side wall of the straight lower part of the cavity of the feeding chamber, two or more Gas baffle; the side wall of the gas-extending range-extending chamber is connected with a ventilation baffle, and the top is provided with a syngas outlet. output. The invention has the advantages of constant melting temperature and high degree of harmless treatment.

Description

Technical field[0001]The present invention relates to the field of solid waste harmless treatment, and more particularly to a fly ash plasma treatment device.Background technique[0002]With the rapid development of the economy, urban waste is also increasing. At present, my country's urban domestic garbage grows at 8% to 10% per year. As the hot value of urban domestic garbage is increased year by year, the output is increasing, and many cities in my country have adopted incineration law to handle urban domestic garbage. After the garbage is burned, some minerals and elements are concentrated into incineration of ash. Among them, the content of toxic elements is more than 10 to 100 times larger than the general soil, and the garbage incineration is a high concentration of two evil. "National Hazardous Waste Directory" has clearly stipulated that domestic waste incineration flying as a hazardous waste, the disposal of fly ash must be carried out in strict accordance with the standards...

AI Technical Summary

Problems solved by technology

However, most of these products are rarely used in my country at present. The main reason is that these gasifiers have high requirements on the selectivity of the charge, high processing costs, and insignificant economic benefits.

[0005] It can be seen that the above-mentioned existing fly ash processing technology obviously still has deficiencies and defects in terms of equipment structure, processing method and use, and needs to be further improved urgently.
