Abstract
A process for preparing multi-element organic fertilizer from the black liquid generated by making paper with alkaline straw pulp includes drying said black liquid by high-temp gas to obtain solid, and mixing it with elements N,P,K,Zn,Fe and B. Its advantages are reducing environmental pollution by 70-80%, and high fertility increased by 15-40%.
Description
The present invention relates to a kind of method with process for preparing multi-element organic furtilizer from extract of black paper-making liquid, mainly utilize alkaline straw pulp paper black liquid, adopt drying means to handle, and with gained waste residue direct production organic potassic fertilizer or synthetic compound multi-element organic fertilizer.
At present, the current techique that alkaline straw pulp paper black liquid is administered is " alkali recovery ", and promptly black liquid is successively through processes such as concentrated, burning, causticizations.This method is to burn whole organism contained in the black liquor, wherein recovery alkali lye is returned again be used for papermaking digesting.But, also have in the black liquid, account for the organism of black liquor solids 65% and the trace element of other availables to plant, can make polynary compoiste fertilizer.Owing to the treatment technology of existing black liquid, in black liquid, obtain the technology of polynary compoiste fertilizer, so this recyclable resource can not be used always.
For fear of the deficiencies in the prior art part, the present invention proposes a kind of method of utilizing black liquid to produce fertilizer, mainly utilize alkaline straw pulp paper black liquid, the employing drying means is handled, reclaim wherein solid, and hang down molecule organic potassic fertilizer or synthetic compound multi-element organic fertilizer with gained waste residue direct production.
Technical scheme of the present invention is characterised in that: with black liquid high-temperature gas drying treatment, and the solid that drying treatment obtains is equipped with the needed multiple elemental substance of plant-growth mixes, moulding obtains compound multi-element organic fertilizer.
Can be before the high-temperature gas drying treatment during pulp cooking, be equipped with the boiling of KOH material, replace the NaOH that adds in the former paper technology, make black liquid contain KOH, the black liquid that will contain KOH then carries out above-mentioned drying, mixing and moulding process to be handled, can the low molecule organic potassic fertilizer of direct production.
Can handle through high temperature drying from the black liquid that contains KOH, the solid that obtains can also be equipped with the needed multiple elemental substance mixing of plant-growth, moulding, can produce multielement potassium base mixed organic manure.
The needed multiple elemental substance of the plant-growth that adds in mixing process can be the material that contains elements such as N.P.K.Zn.Fe.B.
High-temperature gas when being used for drying can adopt steam or high-temperature flue gas.Utilize the heat in the stack gas to make enrichment when concentrated, simultaneously the O in the stack gas
2, SO

The present invention will be in conjunction with the embodiments (accompanying drawing) be further described:
The inventive method is reaction, mass transfer, the heat transfer process of black liquid and stack gas.The flow direction of black liquid is to be introduced into evaporation concentrator (1), and order enters moisture eliminator (2), mixing tank (3) and molding, granulating device (4) then.The flow direction of stack gas is to feed moisture eliminator (2) to enter evaporation concentrator (1) again, and the heat of stack gas is utilized effectively.Solids content is at 13%～16% alkaline straw pulp paper black liquid S
1, in evaporation concentrator (1) with low temperature flue gas S
6Directly mass transfer, heat transfer and chemical reaction are carried out in contact, make the PH of black liquor reduce to 6.5～8 by 14, make moisture evaporation simultaneously, and making black liquor S1 rise to solid content is 25%～35% black liquid S
2Then with the black liquid S that changes
2Send into moisture eliminator (2), with high-temperature flue gas S
6Carry out heat exchange, make black liquid S
2Drying is lower than 10% solid substance S for water content
3Again with solid substance S
3Send into mixing tank (3), with an amount of material S that contains N.P.K.Zn.Fe.B etc. that adds simultaneously
5Carry out compoundly, processing obtains compound multi-element organic fertilizer S in molding, granulating device (4) at last

Can be before the high-temperature gas drying treatment during pulp cooking, be equipped with KOH material S
0Carry out boiling (0), then can replace the NaOH in the black liquor, make black liquid contain KOH, can produce organic potassic fertilizer.
Can be from being equipped with KOH material S
0Carry out pulp cooking (0), the black liquid that is produced is handled resultant through high temperature drying, S
5For containing N.P.K.Zn.Fe.B and the KOH material is compound, can direct production multielement potassium an aromatic plant metioned in ancient books mixed organic manure.
The present invention's advantage compared to existing technology is:
Alkaline straw pulp paper black liquid is processed with high-temperature gas is dry, can reduce the pollution in paper mill 70%～80%, has protected ecology Environment. Reclaimed simultaneously waste residue and made compound multi-element organic fertilizer, fertilizer efficiency improves 5%～40% than the fertilizer efficiency of simple N, P, K. This method implementation condition is simple, saves the energy, is worthy to be popularized very much.
