Abstract

The invention discloses a method for preparing biomass pellet fuel. The biomass pellet fuel comprises husk and mushroom waste residue and is prepared by grinding, drying, granulating and molding, wherein the husk and the mushroom are mixed together in a volume ratio of (3-5): (1-2); the mixed material is dried within the temperature range of 80-120 DEG C; and the water content of the mixed material is controlled to 8-16%. According to the invention, the waste husk, the mushroom waste residue which is discarded after mushroom is produced in forestry by-products and other wastes are utilized to produce the biomass pellet fuel, thus not only turning waste into wealth, saving wood and reducing the production cost, but also brining considerable economic benefit and social benefit for enterprises and the society. The method is simple in technology, is low-carbon and environment-friendly and is high in product calorific value; and additives such as a combustion improver and a bonding agent are not added in the production process.

Description

A kind of preparation method of biomass granule fuel

Technical field

The invention belongs to the comprehensive utilization field of biomass fuel, specifically be meant a kind of preparation method of biomass granule fuel.

Background technology

The raw material resources of production biomass particulate fuel are more extensive, and the difference of basis source can be divided into five types of forest resourceies, agricultural resource, resident living waste and trade waste, MSW and feces of livestock and poultry etc.Utilizing more raw material as the production biomass granule fuel at home at present is forest resourceies and agricultural resource, is the biological particles product of raw material production with agricultural resource (mainly being crop stalk), though production cost is low relatively, the product calorific value is low; Comprise that with the forestry biomass resource scattered timber, brush wood, branch, wood chip, butt, sawdust, slab etc. are the biomass granule fuel of raw material production; Though its calorific value is high; But consume a large amount of timber; And (except that sawdust) will cut, chip, pulverize it in process of production, therefore improved production cost greatly.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art and provide a kind of technology simple, have a preparation method of the biomass granule fuel that low cost, the high and low carbocyclic ring of calorific value protect.

The objective of the invention is to realize like this:

A kind of preparation method of biomass granule fuel comprises the following steps:

1. supply raw materials: be made up of shell and bacterium mushroom waste residue, described shell is one or more in pinecone skin, pineal shell, ear of maize shell, the nut-shell;

2. mix and pulverize: shell and bacterium mushroom waste residue are mixed by the volume ratio of 3～5:1～2, pulverize then;

3. dry: the compound to above-mentioned pulverizing is dry between 80 ℃～120 ℃, and the moisture content of compound is controlled at 8%～16%;

4. granulate: dried material is squeezed into particulate state.

The present invention utilizes to produce the bacterium mushroom slag the like waste that abandons behind the bacterium mushroom in depleted shell and the forestry byproducts; Mix by a certain percentage, through pulverizing, dry, pelletizing forming, production biomass particulate fuel; Can not only turn waste into wealth; Save timber, reduce production costs, also can be enterprise and social considerable economic benefit and social benefit.Compared with prior art, have tangible advantage: the one, because of without timber, saved cutting, chipped, operation such as pulverizing, production cost be lower than use that scattered timber, brush wood, wood are quiet, butt, sawdust etc. are the working method of raw material; The 2nd, kept the high heat energy wood performance of shell institute inherent, the product of producing still has high heating value; The 3rd, reduce production costs simultaneously, having overcome crop stalk is the low defective of granular fuel calorific value that raw material production goes out; The 4th, do not add additives such as any ignition dope, tackiness agent in the production process.In a word, the present invention has promptly solved the comprehensive utilization of waste in the production of forestry process, can produce the cheap relatively renewable energy source of high heating value, cost again.

Embodiment

1. supply raw materials: screening shell and bacterium mushroom waste residue, remove incombustible things such as sandstone, described shell is one or more in pinecone skin, pineal shell, ear of maize shell, the nut-shell;

2. mix to pulverize: get the fixed container, as hold the chest of certain material, respectively shell and bacterium mushroom waste residue are packed in the identical container,, then it is pulverized by the volume ratio mixing of 3～5:1～2;

3. dry: the compound of above-mentioned pulverizing is put in the cylindrical drier, compound is carried out drying, drying temperature is controlled between 80 ℃～120 ℃, and dried mixture moisture content is controlled at 8%～16%;

4. pelletizing forming: dried material put in the ring mode nodulizer be squeezed into granular product;

5. cool off, pack, put in storage.

Claims

1. the preparation method of a biomass granule fuel comprises the following steps:

4. granulate: dried material is squeezed into particulate state.
