Abstract
The invention relates to a clay-free coal ball binder. The clay-free coal ball binder comprises the following components in part by weight: 30 to 38 parts of humic acid-containing lignitic coal, 1 to 5 parts of sodium hydroxide and 60 to 65 parts of water. The binder enhances the binding capacity of coal balls; the strength of the coal balls is improved to 70kg from 60kg; bentonite is saved; fixed carbon in the coal balls is improved to 68 percent from 66 percent; and adaptability of gas making mixed combustion is enhanced.
Description
Technical field
The present invention relates to a kind of coal briquette binding agent.
Background technology
Coal briquette production need be pulverized the coal foam back and be added a certain amount of wilkinite and make binding agent, and extrusion molding after stirring thorough mixing, macerating the system certain hour is gone into Gas-making Furnace and mixed and fire gas behind the drying kiln drying coal briquette moisture content.The coal briquette quality directly influences the operation of the gas making working of a furnace and consumes, when ordinary production, in the coal foam, add a spot of wilkinite and can improve the plasticity-of macerating material coal foam and the thermostability of coal briquette, but can influence the fixed carbon content in the coal briquette behind the adding wilkinite simultaneously, influence is produced and is consumed.Must transform the coal briquette production technique, under the prerequisite that guarantees the coal briquette quality, stop to add wilkinite.
Summary of the invention
The purpose of this invention is to provide a kind of no sooty coal ball binding agent and preparation method thereof.
The technical scheme that the present invention takes is:
A kind of no sooty coal ball binding agent comprises the composition of following weight part ratio: contain brown coal 30-38 part of humic acid, sodium hydroxide 1-5 part, water 60-65 part.
The described brown coal that contain humic acid are the brown coal of the humic acid that contains 1%-40% (wt%), preferably contain the brown coal of the humic acid of 40% (wt%).
The preparation method of no sooty coal ball binding agent comprises the steps:
(1) weighing contains brown coal, water, the sodium hydroxide of humic acid in proportion;
(2) in reaction container, add water, add brown coal and the sodium hydroxide that contains humic acid then;
(3) feed water vapor and be warming up to 80-90 ℃ and constant temperature 30-60 minute.
Coal briquette production need be pulverized the back with the coal foam and be added a certain amount of wilkinite and binding agent of the present invention, extrusion molding after stirring thorough mixing, macerating the system certain hour, drying kiln drying coal briquette moisture content.
The invention has the beneficial effects as follows: the coal briquette viscosifying power strengthens, and coal briquette intensity brought up to 70 kilograms by the tolerances of 60 kilograms of pressure, saved wilkinite and also made the fixed carbon in the coal briquette bring up to 68% by 66%, has strengthened the adaptability that burning is mixed in gas making.After this technology commencement of commercial operation, annual coal briquette output is by 240000 tons, and the wilkinite add-on is by 4%, and 185 yuan of wilkinite prices per ton have reduced surplus in the of 170 ten thousand yuan production cost every year.
