Description

Cleaning sawdust based biomass granule that a kind of ash is few and preparation method thereof
Technical field
The present invention relates to biomass fuel technical field, particularly relate to the cleaning sawdust based biomass granule that a kind of ash is few And preparation method thereof.
Background technology
Along with mankind's increase day by day to energy demand, now widely used oil, coal, natural gas etc. are non-renewable The energy be faced with day by day exhausted problem.The energy crisis that will face to solve the mankind be necessary to develop reproducible newly The energy replaces non-renewable Fossil fuel.Biomass energy, as a kind of cheap, regenerative resource of cleaning, is the most more come More being paid close attention to by people widely, China is as large agricultural country, in the raw material supply of biomass energy, energy demand, government's political affairs The aspects such as the support of plan all have greater advantage.Sawdust, straw source is abundant, and with low cost, sawdust sulfur content is the lowest simultaneously, with it The biomass granule fuel substitute fossil fuels prepared for raw material, to preserving the ecological environment, Development of Social Economy, implementing the energy can Sustainable development strategy has major and immediate significance.But traditional biomass granule fuel utilizing sawdust straw to prepare exists Calorific value slagging scorification boiler low, easy uses dangerous, sulfur content to exceed standard many defects such as pollution environment, ash are big.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the cleaning sawdust based biomass that a kind of ash is few Granule and preparation method thereof.
The present invention is achieved by the following technical solutions:
The cleaning sawdust based biomass granule that a kind of ash is few, is prepared by the raw materials in: sawdust 115-120, Brassica campestris L Straw 50-54, pomelo peel 18-21, cattle manure 17-20, Sulphuric acid waste residue 30-33, Carapax Eriocheir sinensis 14-16, gangue 12-14, aluminium oxide 2-4, waste oil 7-9, polyisobutylene 2-3, MTES 3-4, suitable quantity of water.
The manufacture method of the cleaning sawdust based biomass granule that described a kind of ash is few, comprises the following steps:
(1) sawdust, pomelo peel are put in retort at a temperature of 450-500 DEG C, isolation air carbonization 20-30 minute, cold But to room temperature addition alumina lap 40-50 minute；
(2) being soaked 1-2 hour by gangue 5-10wt% hydrochloric acid solution, washing is to neutral, and add water ultrasound wave at 80-100 DEG C Processing 8-10 minute, then soak 1-2 hour with 8-12wt% sodium hydroxide solution, washing, to neutral, adds water super at 80-100 DEG C Sonicated 8-10 minute, is subsequently adding polyisobutylene, MTES grinding 20-30 minute, dries and prepare modification Gangue；
(3) by rape stalk with hot-water soak 10-12 hour of 60-70 DEG C, filter and put in fermentation vat, control fermentation vat temperature At 30-50 DEG C, humidity is 50-60%, after fermentation process 20-30 hour, adds modified gangue, cattle manure, Sulphuric acid waste residue, Eriocheir sinensis Shell stirs continuation fermentation 10-20 days, is cooled to room temperature and puts into and be crushed to 60-80 mesh in pulverizer；
(4) by step (1), the mixing of (3) material stirring, adding suitable quantity of water and other residual components stirring and evenly mixing, feeding is squeezed into Type machine, is squeezed into a diameter of 5-8mm, the cylindrical particle of a length of 3-8cm with the briquetting pressure of 45MPa, is dried, discharging.
The invention have the advantage that present invention process simple operations is easy, on the one hand sawdust carbonization processed the most modified, Improve toughness and the density of DIC granule, the combustion heat value that improve sawdust carbon residue the volatilization reducing in combustion process Point, the waste gas sulfur content of discharge is low free from environmental pollution, on the other hand, after rape stalk is carried out fermentation process, changes raw material Structure sheaf form the organizational structure of densification, and form the organic material of high-load, improve organic constituent, then will Modified gangue, cattle manure, Sulphuric acid waste residue, Carapax Eriocheir sinensis add continuation fermentation process, and then improve the combustible in organic matter material, Last other effective auxiliary agents of compatibility again are extruded, and the sawdust based biomass granular fuel caking ability prepared is good, and fuel value is high, ash Divide few Air-pollution From Combustion little, be nearly free from the construction of sulfur dioxide and flying dust, beneficially ecological environment.
