Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments do not limit the protection scope of the present invention.

[0032] According to the operating principle of the granulator, the present invention makes full use of economic forests without felling indicators such as mango, coconut and lychee trees; wind falls rubber wood and normally renews the leftovers of rubber wood; wood processing residues (such as fingerboard skin, Slats, wood and bamboo cuttings, saw foam, broken veneer, wood core, wood shavings, wood blocks, leftovers, etc.) and various wastes such as branch wood of various felling index trees to form wood pellet fuel.

[0033] A method for continuous production of wood pellet fuel, such as figure 1 As shown, it includes the following steps:

[0034] (1) Material preparation process: the wooden raw material is chipped, and the length of the obtain...

Abstract

The invention discloses a method for continuously producing a wood granular fuel. The method comprises the following steps: (1) a material preparation procedure, namely chipping a wood raw material to obtain wood chips with lengths less than 3 centimeters; (2) a coarse crushing procedure, namely crushing the wood chips to form coarse wood dust with the grain diameter of 5-6 millimeters; (3) a drying procedure, namely drying the wood dust till the water ratio of the wood dust is 10%-15% by weight; (4) a fine crushing procedure, namely crushing the coarse wood dust to form fine wood dust with the grain diameter less than 3 millimeters again; and (5) a granulating procedure, namely conveying the fine wood dust into a granulator and granulating. The method disclosed by the invention has the outstanding advantages that the application scope of raw materials is enlarged, forestry wastes are sufficiently utilized, equipment provided for a continuous production process is stable in property, high in automation degree and easy and convenient to operate and the energy conservation, emission reduction and safety are achieved.

Description

technical field [0001] The invention relates to the field of biomass fuel production, in particular to a continuous production method of wood pellet fuel. Background technique [0002] The manufacture of existing wood pellet fuel is directly granulated by purchasing wood bran and wood shavings as raw materials. However, the supply of wood bran and wood shavings is unstable, and the wood chips have different shapes, and the moisture content is difficult to control; in addition, the production is mainly manual feeding, which is labor-intensive, and it is difficult to ensure that the conditions of the process parameters are within the appropriate and allowable range. , leading to poor yield quality. Contents of the invention [0003] The object of the present invention is to provide a continuous production method of wood pellet fuel with wide sources of raw materials, high production efficiency, energy saving, environmental protection and continuous uninterrupted operation i...
