Abstract

The present invention discloses a fuel forming process, which comprises: mixing straw, rice husk, sawdust, wood chips and other biomass waste, and adding cotton wool to the obtained mixture; carrying out multiple ignitions, such that the combustion range of the mixture is wide; and directly placing the incompletely-combusting mixture into a fuel forming machine to carry out compression forming. According to the present invention, the cotton wool is added, and the heat produced due to the incomplete combustion of the cotton wool and the raw materials is directly utilized so as to achieve the purpose of heating, such that simplicity and convenience are provided, the time is saved, the forming effect of the raw material is good, the wear on the forming equipment is less, the additional adhesive is not required, and the processing cost is low.

Description

A kind of combust molding technique

Technical field

The present invention relates to a kind of combust molding technique.

Background technology

Fuel forming machine be by rubbish, wood chip or agricultural crop straw and forest harvesting residuum through operations such as pulverizing, dedusting, compression, sizings, be compressed into a kind of curing molding equipment of bar-shaped briquetting.Fuel after compression is in block, and volume is little, and density is large, without any additive.Be convenient to store and transport, make the fuel value of unit surface improve tens times, heat production and anti-refining and middle matter coal close.Its principle of work is: containing certain Mierocrystalline cellulose and xylogen in the materials such as stalk, wherein xylogen is the simple body of structure in material, belongs to the macromolecular compound of benzene propane, has the effect strengthening cell walls, cellulose-binding.Xylogen belongs to noncrystal, and major portion is insoluble to any solvent at normal temperatures, does not have fusing point, but has softening temperature.When temperature reaches certain value, xylogen softens cohesive force and increases, and under certain pressure effect, the dislocation of its cellulosic molecule group, distortion, extension, an inner adjacent biology material connects mutually, reconfigure and compression moulding, material in the course of processing without the need to adding any additive or binding agent.

So existing combust molding technique, often need to adopt various method to come first to be heated up by heating material, period adds various tamanori, complex process, and tooling cost is higher, and molding effect is not fine yet.

Summary of the invention

In order to overcome the combust molding complex operation of prior art, the deficiency that tooling cost is higher, the invention provides a kind of simple and convenient, lower-cost combust molding technique.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of combust molding technique, comprises the following steps:

In the biomass wastes such as stalk, rice husk, sawdust and wood chip, mixing adds cotton-wool;

Lighting a fire in many places, makes the combustion range of mixture wider;

Unburnt mixture is directly put into fuel forming machine compressed moulding.

The invention has the beneficial effects as follows: add cotton-wool, directly utilize the heat of cotton-wool and the generation of raw material incomplete combustion to reach heating object, simple and convenient, save time, the molding effect of raw material is better, and molding device wearing and tearing are lighter, do not need to add extra tamanori, tooling cost is lower.

Embodiment

A kind of combust molding technique of the present invention, comprises the following steps:

In the biomass wastes such as stalk, rice husk, sawdust and wood chip, mixing adds cotton-wool;

Lighting a fire in many places, makes the combustion range of mixture wider;

Unburnt mixture is directly put into fuel forming machine compressed moulding.

Certainly, the present invention, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should within its protection domain.

Claims (1)
