Fly Ash Resource Disposal Technology Uses Oxygen-enriched Air To Assist Combustion

Product Information:

The incineration of domestic waste, water treatment sludge and hazardous waste will produce a large amount of fly ash (accounting for 3% to 5% of the total amount of incinerated waste). Fly ash contains a large amount of toxic heavy metals, as well as highly toxic organic matter such as dioxins. Under certain conditions, these heavy metals and dioxins in fly ash will leach out and pollute water and soil, causing serious impact on the environment and people's lives.

Our company combines the rock wool manufacturing process with the fly ash treatment process, mixes the desalted fly ash with basalt/dolomite in proportion, and melts it in the melting furnace under high temperature conditions of 1300 to 1500°C, using the rock wool manufacturing process Make it into rock wool. After treatment, the melting furnace exhaust gas meets the emission standards.

Product Features:

1. Filter the high-concentration salt-containing wastewater generated after the salt in the fly ash is dissolved and use a multi-effect evaporator to evaporate and crystallize to produce crystallized salt, which can be used in the refined salt process for resource utilization;

2. The operating temperature of the melting furnace is 1300~1500°C, which can completely decompose organic matter and dioxin-like substances in fly ash;

3. The slag is made into rock wool, which can keep heavy metals in the glass, effectively preventing heavy metal pollution;

4. The rock wool produced is of good quality and can be used for industrial heat insulation, generating additional economic benefits;

5. The melting furnace uses oxygen-rich air to support combustion, which greatly reduces fuel consumption during operation, reduces tail gas production, and reduces operating costs;

6. After treatment, all indicators of the exhaust gas can meet the requirements of GB18484 and meet the emission standards.
