Embodiment 1

[0041] The production process of the present embodiment is as follows:

[0042] Step 1. Sieve the cypress sawdust with a water content of 40% through a drum screening machine to remove bulk materials to obtain qualified cypress sawdust with a particle size of ≤3mm;

[0043] Step 2, send the qualified cypress sawdust into the mixing hopper through the raw material hoist, mix according to the ratio of cypress sawdust: cypress shavings=2.5:1, the cypress shavings have a water content of 10%, a diameter of 15mm, and a thickness of 1.5mm;

[0044] Step 3. Send the mixed material obtained after mixing into a rotary dryer for one-time drying. The air supply temperature of the combustion furnace of the rotary dryer is 130° C., and the moisture content of the dried material is 12%;

[0045] Step 4. The dried mixed material is sent to the return fan through the rotary sieve for ventilation and cooling, and the temperature is lowered to 40°C. At the same time, the metal particles in the ...

Embodiment 2

[0051] Step 1, sieve the cypress sawdust with a water content of 45% through a drum screening machine to remove bulk materials to obtain qualified cypress sawdust with a particle size of ≤3mm;

[0052] Step 2. Send the qualified cypress sawdust into the mixing hopper through the raw material hoist, and mix according to the ratio of cypress sawdust: cypress shavings = 2.5:1. The cypress shavings have a water content of 12%, a diameter of 14mm, and a thickness of 1.5mm. ;

[0053] Step 3. Send the mixed material obtained after mixing into a rotary dryer for one-time drying. The air supply temperature of the combustion furnace of the rotary dryer is 125° C., and the moisture content of the dried material is 10%;

[0054] Step 4. The dried mixed material is sent to the return fan through the rotary sieve for ventilation and cooling, and the temperature is lowered to 40°C. At the same time, the metal particles in the mixed material are absorbed by the permanent magnet cylinder;

Abstract

The invention relates to a production technique of a pure cedar biomass granular fuel, which comprises the following steps: screening cedar sawdust, mixing materials, drying, cooling, carrying out secondary mixing on the mixture and cedar shavings, and granulating to obtain the finished product. The technique provided by the invention has the advantages of simpleness, less generated dust, high forming ratio and high yield; and the prepared biomass granular fuel has the advantages of high heating value, low slagging tendency, wide raw material resources and low production cost.

Description

technical field [0001] The invention relates to a preparation process of biomass particle fuel, in particular to a production process of pure cypress biomass particle fuel. Background technique [0002] Commonly used fuels are mostly coal, oil, and gas. These resources are non-renewable resources, which are not conducive to environmental protection and are not conducive to my country's sustainable development strategy. The pellet fuel made from discarded renewable waste resources is biomass pellet fuel. Biomass pellet fuel is not only energy-saving and environmentally friendly, but also has high calorific value, and has little environmental pollution after burning. Reuse is very beneficial to my country's sustainable development strategy. At present, the existing technologies about biomass pellet fuel mainly include the following types: [0003] The application number is 201210316538.4, the application date is August 31, 2012, and the invention patent application with the p...
