Currently, the main Land use systems of maize straw have mechanization chopping and returning, gasifying stalk, gasifying stalk, stalk
Grain feed processing, stalk fermentation ethyl alcohol etc., but in addition to mechanization chopping and returning and pellet feeds from stalks method, other methods are equal
The problems such as that there is technical maturities is not high, investment is big, complex process, accordingly, there exist a large amount of maize straw stockpilings, and
Field is burned, which results in one of serious air environmental pollution and haze Producing reason, and stalk combustion (of oil) insitu
The content of organic matter in soil is reduced, therefore how maize straw to be allowed to turn waste into wealth, fundamentally solves the synthesis of maize straw
Utilizing question is a very urgent project.
A kind of fermentation that microorganism is passed through as raw material using stalk of the Introduction To Cn Patent of Publication No. CN104231116B
Processing and alkaline hydrolysis obtain hemicellulose stoste, the method for humate and feed addictive.It mainly includes the following steps that：Straw powder
Through microbial fermentation facture degrading straw surface wax after broken；After press filtration, lye is added into solid, at heat extraction
Reason, obtains hemicellulose supernatant；Into remaining solid plus lye, the solid for cooking rear press filtration institute is feed addictive；And it filters
In liquid humate solid is obtained containing abundant humate, thickening filtration.This method complex process, production cost are higher；Using
Biofermentation processing, production process technology state modulator require high.
Invention content
The purpose of the present invention is to provide a kind of methods that hydrothermal carbonization maize straw produces humic acid and type briquette fuel.
In order to achieve the above object, the technical solution adopted by the present invention includes：A kind of hydrothermal carbonization maize straw production is rotten
Grow the method for acid and type briquette fuel, it is characterised in that：Using maize straw and water as raw material, agitated mixing, in hydrothermal reaction kettle
Interior generation hydrothermal carbonization reaction makes humic acid be completely converted into water-soluble corruption hydrothermal carbonization product by the way of alkali carries in situ
Sour sodium is grown, sodium humate solution and solid carbonization filter residue is obtained by filtering after reaction, smoke filtrate is acidified, mistake
Filter obtains humic acid, or is concentrated to smoke filtrate, dries and can be obtained sodium humate, and the solid filter residue that is carbonized is mixed with fine coal
It closes, molding, acquisition type briquette fuel.
The beneficial effects of the present invention are：
1, present invention process route is simple, and raw and auxiliary material is cheap, is easy to get, and low energy consumption, and humic acid yield is high.
2, using hydro-thermal method to maize straw hydrothermal carbonization, the yield of humic acid is up to 28.2%, is reacted through hydrothermal carbonization
Afterwards, the calorific value of maize straw carbonization filter residue is enhanced；Meanwhile maize straw volume is obviously reduced, the volume for the filter residue that is carbonized is only
Account for the 30% of corn stalk powder.
3, maize straw hydrothermal product carries out alkali carries in situ, and hydro-thermal reaction and alkali carries can carry out in same reactor, i.e.,
Equipment investment is saved, and has saved industrial water.
4, filter residue mixes the maize straw carbonization after hydro-thermal alkali carries with fine coal, molding prepares moulded coal, improves the hair of moulded coal
The moulded coal burnout rate of heat, preparation is high, and the cold conditions compression strength and fall strength of briquette of type block are higher.
5, after hydrothermal carbonization, tenacity of fibre is destroyed maize straw, as the raw material of preparative briquette fuel, can have been played
The effect of machine binder, and the expansion rate for preparing moulded coal can be effectively reduced, therefore during preparative briquette fuel, be not necessarily to
Addition binder, that is, plastic, efficiently utilizes the maize straw energy.
