Abstract
A kind of coal ash that utilizes is produced the sooty method, a large amount of coal ash with power plant emission are made raw material, and flyash through flotation, is got flotation charcoal and silicon ash, flotation charcoal drying, levigate, homogenizing are handled and are obtained carbon black, and silicon ash drying, classification, levigate, homogenizing are handled and obtained white carbon black.The flyash higher carbon content makes full use of as renewable resource, not only alleviates environmental pollution greatly, and obtains to be worth higher carbon black and white carbon black.
Description
The present invention relates to a kind of is that raw material is produced the sooty method with the coal ash.
Thermal power plant need discharge a large amount of flyash in process of production, and world's year ash discharge slag total amount is about 500,000,000 tons, serious environment pollution.For the protection environment, effectively utilize renewable resource, extensively utilize coal ash to make the raw material of cement raw material and other material of construction both at home and abroad.Because carbon content is higher in the flyash, as cement and other building materials raw materials, its utilization ratio and value are all very low.
The objective of the invention is to provide a kind of flyash is processed into the higher carbon black and the method for white carbon black of being worth.
Invention is achieved in that flyash through flotation, flotation charcoal and silicon ash, flotation charcoal drying, levigate, homogenizing are handled and are obtained carbon black, silicon ash drying, classification, levigate, homogenizing are handled and are obtained white carbon black.
Concrete operations technology of the present invention is as follows:
The flyash water is made into 25% coal ash paste, roughly select by flotation machine, get flotation charcoal and silicon ash, to the flotation charcoal carry out twice selected, the silicon ash is carried out scanning for twice, will through selected and scan after flotation charcoal and silicon ash, respectively with rake thickener dehydration, filter dehydration, water content is reached below 10%, and drying machine oven dry then is ground to granularity less than 40 microns with ball mill again, flotation charcoal after milling and silicon ash, add an amount of coupling agent respectively, use the homogenizer mixing, promptly obtain required carbon black and white carbon black.
Claims (2)
1, a kind of method of utilizing coal ash to produce carbon black and white carbon black, it is characterized in that: with the flotation of flyash process, flotation charcoal and silicon ash, flotation charcoal drying, levigate, homogenizing are handled and are obtained carbon black, silicon ash drying, classification, levigate, homogenizing are handled and are obtained white carbon black.
2, method according to claim 1, it is characterized in that: the flyash water is made into 25% coal ash paste, roughly select by flotation machine, get flotation charcoal and silicon ash, to the flotation charcoal carry out twice selected, the silicon ash is carried out scanning for twice, will through selected and scan after flotation charcoal and silicon ash, dewater with rake thickener respectively, the filter dehydration reaches below 10% water content, drying machine oven dry then, be ground to granularity less than 40 microns with ball mill again, select charcoal and silicon ash after milling, add an amount of coupling agent respectively, use the homogenizer mixing, promptly obtain required carbon black and white carbon black.
