Abstract
A process for producing molded fuel by using agricultural waste belonging to a solid-fuel technology field and the objective is to resolve the problem of waste utilization. The technical scheme is showed as follows: straw, sawdust, wood chips, rice crust, bagasse and other agricultural waste and liquid waste of paper are used as raw materials to produce molded fuel by drying, grinding, mixing, and so on. The invention produces molded fuel with agriculture waste and liquid waste of paper as raw materials, not only saving raw materials costs, but also reducing pollution emissions. And the adhesion of some materials in liquid waste of paper are used without heating block, thus no heating loss, but also reducing the abrasion of mechanical equipment and heat loss of raw materials caused by heating. In addition, liquid waste of paper contains 3 to 5 percent of alkaline substances, which can enhance the activity of combustion. Molded fuel produced by using the process provided by the invention which is characterized in flammability, high heat value, non-polluting, low cost, and so on.
Description
Technical field
The present invention relates to a kind of regeneration treating method of agricultural wastes, particularly utilize papermaking wastewater and prepare the method for shaped fuel, belong to the solid-fuel technology field based on the agricultural wastes of stalk.
Background technology
Waste on the agricultural was very abundant, is example with China, can produce about 6.5 hundred million tons of stalk every year, just reached 7.26 hundred million tons by 2010, was equivalent to 500,000,000 tons of mark coals.Because the general calorific value of agricultural wastes is low, density is little, volume is big, is difficult for transportation, and directly incendiary thermo-efficiency is 10%～30% only, and the direct utilization of agricultural wastes is restricted.In recent years, along with improving constantly of rural economy level, life in the countryside increases gradually with high-grade commercial energy resource in the energy, the shared ratio of stalk is more and more lower, a large amount of depleted stalks are burned in the field, this phenomenon is not only wasted a large amount of biomass energies, and environment is caused severe contamination.At above-mentioned phenomenon agricultural wastes are converted into high-grade energy through deep processing, substitute fossil oils such as part coal, oil, undoubtedly to the situation of alleviating the rural energy anxiety, effectively to administer the pollution that straw burning causes all significant.At present, the agricultural wastes forming technique is with after all kinds of dispersive, the agricultural crop straw that does not have definite shape, sawdust, wood chip, rice hulls, bagasse the like waste drying, the pulverizing, under certain temperature and pressure effect, be pressed into bigger bar-shaped, bulk of shape rule, density or particulate state shaped fuel.Its forming technique that adopts mainly is to rely on the heating back hot-forming, and this mode has problems such as energy consumption height, cost height, and simultaneously, heating also can cause the heat energy loss of equipment wearing and fuel.In addition, the forming technique that has is for increasing the viscosity of shaped fuel, in moulding process, add honey, amylan, clay, tar etc. and make binding agent, this has also improved the production cost of fuel undoubtedly, and clay, pitch etc. make binding agent and also can make forming composition burning slagging scorification serious, and burning is produced certain negative impact.
Summary of the invention
The present invention is used to overcome the defective of prior art and provides a kind of papermaking wastewater that utilizes to prepare the method for shaped fuel for the agricultural wastes that utilize that tackiness agent, normal temperature get final product compression moulding.
The alleged problem of the present invention solves with following technical proposals:
A kind of method of utilizing agricultural wastes to prepare shaped fuel, it is a raw material with stalk, sawdust, wood chip, rice hulls, these agricultural wastes of bagasse and papermaking wastewater, carries out according to following steps:
A. dry: with the seasoning of above-mentioned agriculture waste raw material to water ratio 7.5～20%wb;
B. pulverize: dried agricultural wastes are crushed to particle diameter≤50mm;
C. be mixed: mixed by weight 1000: 50～400 of agricultural wastes after will pulverizing and papermaking wastewater, stir;
D. moulding: the said mixture material is sent into impact briquetting machine be pressed into biomass molding fuel at normal temperatures.
The above-mentioned method of utilizing agricultural wastes to prepare shaped fuel, described biomass molding fuel are diameter 25～80mm, the right cylinder of length 30～80mm, or the length of side is square or the rectangular parallelepiped of 25～100mm.
The above-mentioned method of utilizing agricultural wastes to prepare shaped fuel, the forming pressure of described impact briquetting machine are 10～60MP.
The present invention is the feedstock production biomass molding fuel with agricultural wastes and these two kinds of refuses of papermaking wastewater, has both saved raw materials cost, the pollution that alleviated again that papermaking wastewater pollutes and agricultural wastes are burnt the grass on waste land.Utilize the adhesive effect of some materials in the papermaking wastewater to make and need not heating in the agglomeration process, thereby do not have heating energy loss, alleviated the equipment wearing that causes by heating and the heat energy loss of raw material simultaneously.In addition, contain 3～5% alkaline matter in the papermaking wastewater, combustion activity is strengthened.With the shaped fuel of the inventive method preparation have inflammable, calorific value is high, pollution-free, characteristics such as cost is low, can be used as cooking, heating fuel, also can be used as the fuel of Industrial Boiler and power plant, has good society, economy, environmental benefit.
Embodiment
The inventive method directly use papermaking wastewater according to certain adding proportion as the biomass molding fuel additive, it utilizes solid substance in the papermaking wastewater to comprise the degradation product of xylogen, Mierocrystalline cellulose, hemicellulose and organic acid etc., the carbohydrate that these materials generate plays cohesive action, direct compression moulding can be in the shaped fuel preparation process, need not to heat, but also the lax density and the weather resistance of shaped fuel can be improved.In addition, generally speaking, contain 3～5% alkaline matter in the papermaking wastewater, combustion activity is strengthened, the thermal value of the lignin in the black liquor can reach 6000kcal/kg.Directly using papermaking wastewater to be additive, can reach the purpose that need not to heat the raising bonding force, can farthest reduce the production cost of biomass molding fuel again, also can realize utilization of waste material, is killing three birds with one stone.
Several specific embodiments below are provided:
Embodiment 1: choose agricultural wastes seasoninies such as stalk, sawdust, wood chip, rice hulls, bagasse to water ratio 7.5%wb, dried agricultural wastes are crushed to particle diameter 40mm; With the agricultural wastes after pulverizing and papermaking wastewater by weight 1000: 50 mixed, stir; The said mixture material is sent into impact briquetting machine be pressed into diameter 25mm with pressure 60MP at normal temperatures, the right cylinder biomass molding fuel of length 30mm.
