Production device and manufacturing method for preparing granular fuel by mixing sanding powder and rice hulls

Abstract

The invention discloses a manufacturing method and production device for preparing granular fuel by mixing sanding powder and rice hulls. The manufacturing method comprises the following steps that a,the sanding powder is collected, and the rice hulls are crushed to form rice hull powder; b, the sanding powder and the rice hull powder are mixed, stirred and humidified; c, the sanding powder and the rice hull powder are subjected to standing and homogenized; d, a mixture of the sanding powder and the rice hull powder is manufactured into the granular fuel; e, the formed mixture is sieved and graded; and f, the qualified mixture after sieving and grading is ventilated, dried and dehumidified. The production device comprises a material amount signal collecting control device, a raw materialcrushing and stirring device, a raw material forming and screening device and a fuel drying and packaging device; and the raw material crushing and stirring device communicates with the raw material forming and screening device, and the raw material forming and screening device communicates with the fuel drying and packaging device. Agricultural processing residues and the sanding powder are mixedto prepare the formed fuel, the formability of the fuel is improved advantageously, and the quality of the formed fuel is improved.

Description

technical field [0001] The invention relates to a production device for preparing granular fuel by mixing sanding powder with rice husk and a manufacturing method for preparing granular fuel by mixing sanding powder with rice husk, and belongs to the technical field of biomass energy utilization. Background technique [0002] Biomass briquette fuel technology is one of the important technical directions of biomass energy utilization, and it is also one of the key development areas of biomass energy in my country. A large amount of sanding powder will be produced during the production of wood-based panels. According to statistics, a production line with an annual output of 100,000 m3 of fiberboard produces about 10 tons of sanding powder per day. Raw material, and good formability as wood powder sanding powder. Sanding powder is one of the main processing residues in wood-based panel factories. Many factories directly feed sanding powder into the chain furnace as fuel. Due t...

Problems solved by technology

Sanding powder is one of the main processing residues in wood-based panel factories. Many factories directly send sanding powder into the chain furnace as fuel. Due to the mismatch of combustion methods, the combustion efficiency is low and the pollutant discharge is not up to standard.

Rice husk is the main residue in rice processing. The moisture content of rice husk after rice processing is also relatively low, and it does not need to be dried to prepare granular fuel, but the surface of rice husk is relatively smooth, and the molded fuel prepared from pure rice husk has poor formability and fuel properties. wood raw material

In the prior art, there is a lack of methods and devices for the fusion of sanding powder and rice husk to prepare granular fuel, and there is an urgent need for improvement.
