Description

Stirring device for steam explosion and using method thereof

Technical Field

The invention belongs to the technical field of organic matter pretreatment equipment, and particularly relates to a stirring device for steam explosion and a using method thereof.

Background

The straw is one of the most abundant biomass energy sources in the world, and the straw resources in China are very abundant. The straw is mainly composed of cell contents such as cellulose, hemicellulose, soluble protein, sugar and the like. Most of straws are consumed in the forms of combustion, padding and the like, and the straw combustion not only loses a large amount of biological resources, but also causes environmental pollution. In recent years, the comprehensive utilization of straws is receiving more and more attention. The straw can be made into feed and fertilizer, and can also be used for power generation, paper making and the like.

Steam explosion, namely steam explosion, is a technology for pretreating biomass in an explosion process realized by using a steam ejection principle. The technical essence is that the steam molecules permeating into the plant tissue are released instantly, so that the internal energy of the steam is converted into mechanical energy and acts on the cell layers of the biomass tissue, and the raw material is decomposed according to the purpose by using less energy. The method not only avoids the secondary pollution problem of chemical treatment, but also solves the problem of low biological treatment efficiency at present, and is the most promising pretreatment technology in the field of biomass conversion.

The sugar yield of the rape straw after the steam explosion treatment is obviously improved and is 3.4 times of the direct enzymolysis content of an untreated sample, and the content of various water-soluble sugar compounds is also greatly improved, wherein the content of glucose and the content of xylose are respectively 3.5 times and 4.7 times of the direct enzymolysis content of the untreated sample. 40, 12 and 1 fatty acids, aromatic and furan substances are respectively detected in the ethyl acetate extract of the water extract. The surface appearance structure of the treated rape straws is observed through a scanning electron microscope, and the surface structure of the treated straws is loose, the specific surface area is increased, and the accessibility of enzyme to cellulose is increased.

Because the steam permeation time of herbaceous substances such as straws and the like is generally less than 1 second, the air release time of steam explosion equipment cannot be more than 0.1 second, and pressure difference can be generated to destroy the lattice structure of cellulose and generate a real steam explosion effect. The blasting time of the ejection type steam explosion equipment which is widely used at present is 0.00875 second, which meets the necessary condition.

The main influencing factors of the steam explosion process are material internal cause and equipment external cause. The internal factors of the materials are the types and the tissue components of the materials, the water content, the pre-soaking, the chemical pretreatment, the crushing degree, the fluidity and the like; the external factors of the equipment are steam pressure temperature, steam components, pressure maintaining time, blasting and air bleeding time and the like. These factors are also parameters of the steam explosion process in a narrow sense. The steam pressure and the pressure maintaining time can be controlled by a user and are the most common main comparison parameters in the experiment.

9. An agitation apparatus for steam explosion according to claim 8, wherein: the top of blasting jar top cap (103) is provided with power component (3), power component (3) are connected with blasting jar top cap (103) through shock absorber support (301).

10. A method of using an agitation apparatus for steam explosion according to claim 9, wherein: the method comprises the following steps:

s1: preparing straws, namely firstly, filling straw scraps into a storage tank (2), and distributing the straws in a distributing upper cavity (5) connected with the lower end of the storage tank to prepare for blasting feeding of the straws;

s2: straw powder is radially distributed, the straw entering the upper distribution cavity (5) falls into the distribution guide assembly (53) under the action of gravity, the distribution motor (511) is started, power is transmitted to the distribution guide assembly (53) under the action of the distribution main gear (512) and the distribution pinion (513), the distribution guide assembly (53) enables the straw to flow leftwards and rightwards, and the distributed straw respectively enters a left cavity (5314) and a right cavity (5315) at the lower part;

s3: the straw powder is radially stirred, when the power spindle (514) rotates, the stirring driving gear (5326) is driven to rotate along with the power spindle, power is transmitted to the stirring shaft (5324) through the stirring driven gears (5325) meshed with the two sides of the stirring driving gear (5326), the stirring sheets (5323) connected with the stirring shaft are driven, the straws guided from the upper part of the straws are radially stirred towards the central axis of the material distribution lower cavity (533) by the first radial stirring part (5321) and the second radial stirring part (5322), and finally the straws in the material distribution lower cavity (533) are sent into the blasting tank body (10) connected with the lower part through the material distribution outlet (5321) to be subjected to steam blasting;

s4: and in the steam explosion step, after the straws are uniformly stirred in the explosion tank body (10), all outlets or inlets on the explosion tank assembly (1) are closed, steam is applied, the pressure is kept at 5MPa, 10-20S is maintained, then the discharge port (105) is opened within 0.01S, and meanwhile, the power assembly (3) is started to stir the straws, so that the discharge process is accelerated.
