Description
Technical field
The invention belongs to agricultural technology fields, and in particular to a kind of method of co-producing bio matter charcoal and fertilizer.
Background technology
How agricultural wastes to be carried out efficiently utilizing the research hotspot in always agricultural technology.By taking stalk as an example, most
Early straw utilization mode is straw-returning.There are two types of traditional straw-returning modes, respectively stalk crush direct returning to farmland and
Stalk on-site incineration is made after plant ash and carries out returning to the field again.But stalk directly crushes and carries out returning to the field and easily lead to pest and disease damage and ask
Topic；And by although returning to the field will not bring pest and disease damage problem, open incineration that can cause organic in stalk again after stalk on-site incineration
The waste of matter, a large amount of dense smokes generated in burning process can also cause serious air pollution.The above problem makes people always
Seek the new way using agricultural wastes, in recent years, it is more as studying to prepare biomass carbon using agricultural wastes
A kind of new method.
Agricultural wastes are pyrolyzed under limit oxygen or anoxic condition, are carbonized, you can obtains biomass carbon, while can also
Obtain the by-products such as stalk oily (or wood tar), wood vinegar.Wherein, wood vinegar contains a variety of active ingredients, including a variety of organic
Matter such as organic acid, aldehyde, ketone, alcohol, phenol etc., also plant growth necessary element such as calcium, magnesium, sodium, iron etc., so wood vinegar is not
Only have effects that desinsection, sterilization, while the growth of plant can also be promoted.Biomass carbon can be used as soil conditioner or be used for
Carbon-based fertilizer etc. is prepared, and wood vinegar can be used for making medical material, food additives, plant growth promoter etc..Wood vinegar at
It is point more complex, containing water-soluble substances such as phenols, carboxylic acids, alcohols, also containing a small amount of wood tar and suspended matter, so applying
It needs first to refine before, when making different purposes, required refined degree is different.It is that one kind can using wood vinegar production liquid fertilizer
Make full use of the mode of wood vinegar active ingredient.Wood tar and suspended matter contained in wood vinegar are unfavorable for wood vinegar and directly use
It is applied to crop as Liquid Fertilizer, when preparing Liquid Fertilizer using wood vinegar in the prior art, often first using the methods of absorption, distillation
Wood vinegar is carried out to remake use after suitably refining.
For example, Chinese patent literature CN103724128A discloses a kind of method preparing foliar fertilizer using wood vinegar,
The technology aoxidizes wood vinegar first with hydrogen peroxide, then active carbon adsorption and ion exchange resin is used to adsorb successively
Method by after oxidation macromolecular and other impurity remove, then wood vinegar is concentrated using reverse osmosis membrane so that the wooden vinegar
Nutritional ingredient is enriched in liquid, is subsequently added into the additives such as humic acid, magnesium sulfate as nutritional supplementation, blade face is made in last coating
Fertilizer.But not only process is complicated, complex steps for the foliar fertilizer technology of preparing, production cost is also higher, it is also necessary to consume dioxygen
Water, ion exchange resin and reverse osmosis membrane；Also, the loss of organic matter will certainly be caused in preparation process, such as science and technology
Paper《Application of the membrane technology in wood vinegar purifying process》Middle announcement, when using the reverse osmosis concentration for carrying out wood vinegar, meeting
There is nearly 10% small molecule organic matter to be detached from wood vinegar with dilute side.
For another example Chinese patent literature CN105669257A discloses a kind of sunflower stalk, pachyrhizus stalk and peanut straw system
The method of standby wood vinegar Water soluble fertilizer.The technology by sunflower stalk, pachyrhizus stalk and peanut straw by being first granulated destructive distillation again, gas phase
Crude pyroligneous acid is obtained after product condensation, 8~10 hours is stood after crude pyroligneous acid is evaporated under reduced pressure, takes middle layer air-distillation 3 again
~5 hours, acetum pyrolignosum rectificatum liquid is obtained, is used as wood vinegar Water soluble fertilizer.As it can be seen that the processing time of crude pyroligneous acid need to be up in the technology
Ten more than hour, and be evaporated under reduced pressure and air-distillation also needs to consumption mass energy, this undoubtedly substantially increases and is produced into
This.
Therefore, how efficient, simple, low cost using wooden while active ingredient in reservation wood vinegar to greatest extent
Vinegar liquid prepares Liquid Fertilizer and is a problem to be solved by those skilled in the art.
Invention content
