Description
Technical field
The utility model relates to a kind of agricultural machinery, particularly one granulation curing range.
Background technology
Gasoline is one of main energy sources kind of current mankind use, but gasoline is a kind of non-renewable energy resources, and can produce a large amount of carbon dioxide and other air pollutants in the production and use procedure of gasoline, causes serious problem of environmental pollution.Ethanol be a kind of can the novel renewable energy of replacing gasoline.The raw materials for production of first generation ethanol are the cereal crops such as soybean and corn.Although production technology is ripe, a large amount of productions of first generation ethanol certainly will cause the dispute of " strive grain with the people, strive ground with grain ".Second generation ethanol is with non-cereal crops-living beings (such as maize straw, straw, Sunflower Stalk, sorghum stalk, the crops residues such as Alfalfa, wheat straw and peanut seedling)-as the cellulosic ethanol of raw material.But the production technology of cellulosic ethanol is complicated more than first generation ethanol.At present, the production technology of cellulosic ethanol is also immature, and therefore the research of this respect has been subject to the common concern of countries in the world academia.
The main Types that traditional biomass is granulated has that roller is shaping, screw extruding is shaping, piston punch forming.These traditional compression methods generally all need high-temperature steam, high pressure and extra interpolation bonding agent.And because equipment is huge and price is high, be difficult to carry out compressed biomass process in biomass material grown place.If biomass material is transported to alcohol production ground carry out compression process again, its freight must be exceed much than the expense of transporting biomass particle.
The large-scale production of current cellulosic ethanol is subject to the restriction of two technical problems: 1) density of biomass material is very low, only has 40-250kg/m3.Which increasing cellulosic material in transport, store and cost (approximately account for 80% of cellulosic ethanol total cost of production) .2 in use procedure) pre existing processing method efficiency is on the low side, causes the pretreated expense of costliness.
Utility model content
The purpose of this utility model is to provide a kind of ultrasonic vibration auxiliary granulation and curing range, reduces energy ezpenditure, reduces biomass fuel production cost.
The purpose of this utility model is achieved in that a kind of ultrasonic vibration auxiliary granulation and curing range, comprise the forcing press be arranged on above particle mould, the lower end of press ram is fixedly connected with ultrasonic transducer through snap ring, the lower end of ultrasonic transducer is fixedly connected with ultrasonic transformer through retainer ring, ultrasonic transformer can move downward and stretch into particle mould, the extraction particle mould that moves up is arranged, and described ultrasonic transducer is connected with supersonic generator.
During utility model works, first by living beings as rear pulverizing air-dry under natural conditions, then the powdered biomass of pulverizing is inserted in particle mould, open supersonic generator regulating power and frequency, supersonic generator produces sine or the pulse signal of certain frequency, conduct to ultrasonic transducer by cable link, the transform electrical signals that supersonic generator provides by ultrasonic transducer is again mechanical oscillation, moved down by controlled pressure compressing head, then drive snap ring that ultrasonic transformer is moved to particle die surface, ultrasonic wave occurs to coordinate ultrasonic transducer to keep ultrasonic transformer end portion vibration, vibration creates energy and produces heat, ultrasonic transformer moves down by recycling servomotor, down pressure is applied to powdered biomass simultaneously, compression is cured carry out simultaneously, after the compression of setting-up time, particle is obtained after taking mould apart.Compared with prior art, the beneficial effects of the utility model are, the utility model by the curing of living beings, to compress and pretreatment combines simultaneously, avoid high-temperature steam, the use of high pressure and additive, can in the places of origin of raw materials directly biomass granulating, improve density and the shock resistance degree of biological particles, further increase out sugared rate, and possess following three functions: 1) improve biomass density, reduce cost of transportation; 2) improve living beings aridity and reduce bacteria breed, being beneficial to living beings and storing for a long time; 3) improve living beings and go out sugared rate, improve ethanol production.The utility model can be used in stalk recovery.
