Abstract
The invention provides a preparation method of a coal rod binder. The preparation method is characterized by comprising the following steps: adding sodium hydroxide and water into a retort at a mass ratio of 1:(30-45), and evenly mixing; then heating to 90-110 DEG C, smashing brown coal with more than 3% of humic acid until the particle size is less than 5mm; adding smashed brown coal the mass of which accounts for 50%-80% of that of water into the retort, then closing and stirring, wherein the reaction temperature of the retort is maintained between 90-110 DEG C; and reacting for 45-60 minutes so as to prepare the coal rod binder. According to the invention, the conversion rate of sodium humate can reach above 90%; and the production cost of the coal rod binder is lowered, and the waste of brown coal resources is also reduced.
Description
Technical field
The present invention relates to a kind of preparation method of coal rod binding agent, particularly relate to a kind of preparation method of binding agent of low fixed carbon coal.
Background technology
With low fixed carbon coal is raw material when producing the unstripped gas of synthetic ammonia, will hang down the fixed carbon coal earlier and make the coal rod, and the coal rod is put into the unstripped gas of producing synthetic ammonia in the Gas-making Furnace then.Low fixed carbon coal is the general sodium humate binding agent that adopts when making the coal rod, mainly produces the sodium humate binding agent with brown coal at present.When producing the sodium humate binding agent with brown coal now, adopt the technology add brown coal continuously, the interior temperature of stove is difficult to unanimity like this, causes the sodium humate transformation efficiency only about 60%, has not only increased production cost, and has wasted resource.
Summary of the invention
The objective of the invention is problem, provide at above-mentioned existence
OnePlant the preparation method of the high coal rod binding agent of sodium humate transformation efficiency.
The present invention is achieved in that sodium hydroxide and water add retort by mass ratio 1:30～45, heat after stirring to 90～110 ℃, with content of humic acid is that brown coal powder more than 3% is broken to below the granularity 5mm, the brown coal that crush add the retort rear enclosed by 50%～80% of quality and stir, the temperature of reaction of retort remains between 90～110 ℃, and reaction carries out making after 45～60 minutes coal rod caking agent.
The present invention adopts intermittent feeding technology, has avoided decline of retort temperature and inhomogenous problem in the continuous charging process, has improved the sodium humate transformation efficiency, reaches more than 90%.Use the present invention not only to reduce the production cost of coal rod binding agent, and reduced the waste of lignite resource.
Embodiment
Below in conjunction with embodiment the present invention is specified.
1, sodium hydroxide and pH value are that 6～8 water adds retort by mass ratio 1:30～45, heat after stirring to 90～110 ℃;
2, be that brown coal powder more than 3% is broken to below the granularity 5mm with content of humic acid, the brown coal that crush add the retort rear enclosed by 50%～80% of quality and stir, and the temperature of reaction of retort remains between 90-110 ℃;
3, after reaction is carried out 45-60 minute, survey its pH value, make coal rod caking agent, after the tap valve of retort is emitted, can use at 8～10 o'clock.
Claims (1)
1. the preparation method of coal rod binding agent, it is characterized in that sodium hydroxide and water add retort by mass ratio 1:30～45, heat after stirring to 90～110 ℃, with content of humic acid is that brown coal powder more than 3% is broken to below the granularity 5mm, the brown coal that crush add the retort rear enclosed by 50%～80% of quality and stir, the temperature of reaction of retort remains between 90～110 ℃, and reaction carries out making after 45～60 minutes coal rod caking agent.
