Abstract

The invention pertains to a forming process of biomass fuel, which is characterized in that the invention is formed by preparation of components and the technique processing and the weight ratio of main components are that: straw of 20-95, and starch of 2-60. The production technique process comprises the straw, grinding, sieving, starch, hydrolysis, forming starch paste, compounding, molding and drying processes. 10-120 meshes are sieved; Hydrolyzed starch /water=1/5-40; the molding adopts a pouring of mould vibration or an extrusion molding; a drying temperature ranges from 1-150 DEG C. The process has the advantages of simple technique, low investment, fast effect, low cost, convenience to popularize, and also the more ideal molding method of utilizing plant straws, fruits, rhizomes and organic refuse.

Description

Biomass fuel forming method

Technical field

The present invention relates to biomass fuel forming method, be a kind of be the biomass fuel forming method of main raw material with straw, rhizome, fruit, organic waste.

Background technology

At present, development and use were paid much attention to biomass fuel both at home and abroad, and Japan just develops bar-shaped biological substance fuel forming machine in the fifties, and the U.S. has also developed biomass molding fuel in 1976.And China also developed the screw-pushing type forming machine for straw in 80 years, but because the molding device energy consumption is big, fragile, production efficiency is low, the shaped fuel cost height of producing, and it is big to add in the production process dust, reasons such as operating environment is bad are not also pushed open so far.

In recent years, along with the raising of life of farmers level, stalk no longer is the necessary energy of life of farmers, and most of stalk burns everywhere, has both wasted the energy, has caused environmental pollution again.

Summary of the invention

The purpose of this invention is to provide a kind of biomass fuel forming method, it is big to have solved the prior art energy consumption, fragile, production efficiency is low, and dust is big in the production process, and operating environment is bad, so far also do not push open, cause most of stalk to burn everywhere, both wasted energy, cause environmental pollution problems again.

The object of the present invention is achieved like this: its main ingredient weight proportion of this biomass fuel is as follows: 20～95 parts of stalks, 2～60 parts of starch.

Its production technique comprises stalk, pulverizes, sieves, starch, hydrolysis, slurrying are stuck with paste, be mixed, 10～120 orders are sieved in moulding, drying process, the starch hydrolysis, starch: water=1: 5～40, mould vibration casting or mould extrusion molding, 0～150 ℃ of drying temperature are adopted in moulding.

Stalk: adopt corn, rice, wheat, the various straws of cotton branch, rhizome and organic waste wherein at least a.

Starch: adopt corn, Ipomoea batatas, the various fruit starch of potato and rotten starch wherein at least a.

This invention compared with prior art has the following advantages: (1) technology is simple, invest little, instant effect; (2) moulding can be electronic can be manual, energy consumption is low, the efficient height; (3) cost is low, is convenient to promote; (4) resource is extensively renewable, and the rubbish after the use can be made fertilizer, non-environmental-pollution.

Embodiment

Embodiment 1, its main ingredient weight proportion of biomass molding fuel: 20～95 parts of stalks, 2～60 parts of starch.

Its technological process of production such as Fig. 1 comprise stalk, pulverize, sieve, starch, hydrolysis, slurrying are stuck with paste, be mixed, moulding, drying process.

Specification

1, stalk: adopt corn, rice, wheat, cotton, the various straws of branch, rhizome, furfural dregs, sugared slag and organic waste, wherein at least a.

2, pulverize: adopt pulverizer.

3, sieve: cross 10～120 mesh sieves, get sieve particle powder down.

4, starch: adopt corn, potato, the various fruit starch of Ipomoea batatas and rotten starch wherein at least a.

5, hydrolysis: in starch: the ratio of water=1: 5～40 adds water, and amount of water is relevant with molding mode and raw material.

6, slurrying is stuck with paste: hydrolyzed starch is put into the well heater that band stirs, and stir on the limit, the limit heating, is heated to 100 ℃ and becomes paste to end.

7, be mixed: by weight ratio stalk and paste are poured in the stirrer, stirred.

8, moulding: the material vibration casting that will be mixed is in mould or by the mould extrusion molding.

9, drying: adopt seasoning or oven dry, 0～150 ℃ of controlled temperature.

Embodiment 2, its main ingredient weight proportion of biomass molding fuel: 60～80 parts of stalks, 10～60 parts of starch, 0～10 part of sanitas, 0～10 part of fire retardant, 0～10 part of water-resisting agent.

Its technological process of production comprises stalk, pulverizes, sieves, starch, hydrolysis, slurrying paste, additive, be mixed, moulding, drying process.
