Abstract
A fluidized bed fly ash activating agent which is a liquid activating agent including following main components: a solid additive formed by mixing fly ash from power plants and water granulated slag generated through blast furnace ironmaking, a sodium hydroxide solution being 40% in concentration, and sodium silicate being 5% in concentration. The activating agent can enhance activity of the fluidized bed fly ash and enables activity index of inactive fluidized bed fly ash under a normal situation to be not less than 70%.
Description
Technical field
The present invention relates to a kind of fluidization bed fly ash activator, especially can change the activator of fluidization bed fly ash curing performance.
Background technology
At present, the feature that fluidization bed fly ash sinters due to its cold cycle, cause Circulating Fluidized Bed Ash to form glassy phase and cause active relatively low, in addition fluidized bed ash is in sintering process, be added with excessive lime, larger impact produced on itself gel time and intensity, causes fluidization bed fly ash activity lower, cannot solidify after aquation, produce intensity, cannot as conventional boiler ash for paving the way, building, the field such as well cementation.The fluidization bed fly ash that cannot carry out utilizing can only use the mode process of burying, and produces larger environmental influence.
Summary of the invention
In order to overcome existing fluidization bed fly ash non-activity, the conventional problem utilized cannot be carried out, the invention provides a kind of activator that effectively can improve fluidized-bed activity, the curing performance of fluidization bed fly ash can be changed, make the fields such as it can be applied in paving the way, build, well cementation.
The technical solution adopted for the present invention to solve the technical problems is: in fluidization bed fly ash, add active ash, active particle, combination ash entirety is made to form homogeneous bulk, fly ash grain is connected by active substance in ash, form the reticulated structure that flyash is connected with activeconstituents, by adding basic solution, the molecular scission in compounding substances can be made, hydration reaction is carried out with water, form the curable structure of similar water mud, with the fine coal that this activator activates, after there is curable, solidification, have the feature of some strength.
The invention has the beneficial effects as follows, solve the problem of fluidization bed fly ash non-activity, fluidization bed fly ash can be solidified, be applied to the fields such as well cementation of paving the way.Solve the environmental problem that fluidization bed fly ash buries process generation.
Claims (4)
1. a fluidization bed fly ash activator, is characterized in that: the activity improving fluidization bed fly ash, and the fluidization bed fly ash that originally cannot solidify can be solidified.
2. fluidization bed fly ash activator according to claim 1, is characterized in that: be divided into solid additive and liquid basified activator.
3. fluidization bed fly ash activator according to claim 1, is characterized in that solid additive is the mixture of the grain slag that fly ash in electric power plant and blast furnace ironmaking produce.
4. liquid basified activator composition is the sodium hydroxide solution of concentration 40% and the mixing solutions of 5% water glass.
