Problems solved by technology

[0005] The purpose of the present invention is to overcome above defect, provide a kind of method that utilizes biomass industrial production waste to produce granular fuel, make all the waste that produces in the biomass industrial production process no matter how much water can be burnt as fuel after granulation, In this way, the waste from biomass production can be comprehensively utilized to turn waste into treasure; and to overcome the complex process of producing pellet fuel in the past, it is necessary to add additives such as binders and combustion enhancers to produce qualified pellet fuel, and to overcome the high technical requirements in the production process , the disadvantage of high product cost

Embodiment Construction

[0015] According to the process flow shown in the attached figure, the drying, granulation, cooling, screening and other systems of biomass industrial waste are installed and connected. Taking furfural slag as an example,

[0016] The furfural slag is loaded into the hopper of the belt conveyor 1 with a forklift and falls onto the vibrating screen 2 along with the belt conveyor. The large particles and sundries are screened out by the vibrating screen 2 and then crushed and returned to the vibrating screen. The furfural with qualified particle size The slag is sent to the scattered air dryer for drying along with the heated air. In the steam heat exchanger 3 , air and steam enter into the steam heat exchanger 3 , condensed water flows out from the bottom, and the heated air is sent into the diffuse air dryer 4 .

[0017] The pipe diameter of the scattered airflow dryer 4 is alternately reduced and expanded, so as to fully exert the high heat and mass transfer function of the ...

Abstract

The method of producing granular fuel with industrial biomass waste belongs to the field of comprehensive utilization technology. Industrial biomass waste with water content of 30-35% is first extruded to form in a ring mold type pelletizing machine while softening material with the heat generated during extruding formation, and then cooled and sieved to obtain the product. The present invention utilizes industrial biomass waste effectively and is environment friendly, and the produced granular fuel may be used to replace charcoal for warming, barbecue, etc.

Description

technical field [0001] The invention relates to the field of environmental protection and comprehensive utilization of biomass industrial production waste, in particular to a method for producing granular fuel by utilizing biomass industrial production waste. Background technique [0002] At present, due to the reduction of non-renewable energy sources worldwide, my country and even the world are paying more and more attention to the comprehensive utilization of renewable biomass energy. Biomass industrial production enterprises such as plant straws and wood scraps, such as: furfural / furfuryl alcohol production plants, xylose / xylitol production plants, pulp production plants, glucose and alcohol production plants, etc., all use plants in the production process The cellulose, hemicellulose in the plant, and other components such as lignin in the plant are discharged as industrial waste. Due to the different products and production processes of each production plant, the mois...
