Abstract
The utility model discloses a van-type continuous feeding and discharging anaerobic digester which mainly consists of a feeding hole, a fermentation chamber, an air storage chamber, a discharging hole and an air duct. The main body of the van-type continuous feeding and discharging anaerobic digester is of a rectangular shell structure, wherein the upper part of the main body is provided with a baffle and a guide cross beam, the lower part of the main body is provided with the fermentation chamber, and the bottom of the fermentation chamber is provided with a transmission device. A fermentation van filled with straws enters the digester from the feeding hole; the guide cross beam and the transmission device mutually act to fix the fermentation van in the vertical direction and totally dip the fermentation van in fermentation liquor; the fermentation van is driven by the transmission device so as to be pushed in sequence to the discharging hole direction; after fermentation is finished, the whole van discharges materials, the residual solid substance after fermentation is left in the fermentation van, and liquid flows back to the fermentation chamber; and methane generated by anaerobic digestion is stored in the air storage chamber and is led out via the air duct. The van-type continuous feeding and discharging anaerobic digester has the advantages of high fermentation efficiency, small operation power consumption and the like, and can be used for improving the working efficiency of generating the methane by virtue of anaerobic digestion.
Description
Technical field
The utility model relates to a kind of anaeroic digestor that can handle stalk product biogas continuously, can realize that especially fermentation materials turnover digestive organ is smooth and easy, aerogenesis is evenly distributed, gas producing efficiency high.
Background technology
At present, be used to handle the anaeroic digestor that agricultural crop straw produces biogas and mainly contain two kinds.A kind of is to be improved by the anaeroic digestor of handling the animal dung thing to form; This digestive organ needs stalk such as is pulverized at pretreatment operation, and facility investment is big, and energy consumption is high; And after fermentation materials gets into digestive organ; The material crust that floats easily, and fermented liquid total solids level (TS) is high slightly, just can cause normally discharging of fermentation materials.Another kind is the sequence batch (anaeroic digestor, its aerogenesis skewness weighing apparatus, and the peak period gas production rate is high, and gas production rate is low thereafter, and anaerobic digestion efficient is low, the input-output ratio.
Summary of the invention
Produce the deficiency that biogas digestive organ operation is complicated, fermentation efficiency is low in order to solve existing stalk fermentation; The utility model provides a kind of van-type continuous feeding and discharging anaeroic digestor; This device can be simplified the stalk preprocessing process; Effectively prevent stalk come-up crust, and input and output material is convenient, running maintenance is simple, fermentation efficiency is high.
The utility model solves the technical scheme that its technical problem adopted: van-type continuous feeding and discharging anaeroic digestor is made up of opening for feed, proving room, gas dome, gas tube, top cover, guiding crossbeam, dividing plate, discharge port, digestive organ main body and transmission mechanism.The digestive organ main body is the rectangular parallelepiped shell structure, and the top opens wide, and digestive organ main body top is provided with dividing plate; Dividing plate and digestive organ main body minor face parallel sidewalls; Separating digestive organ main body top is three parts, and both sides are respectively opening for feed and discharge port, and middle part and top cover, fermented liquid liquid level constitute gas dome.Top cover is a taper hexahedron shell structure, and the bottom opens wide, and minor face overlaps with dividing plate end face center line, and long limit, bottom overlaps with digestive organ main body top longitudinal edge, and the top cover top is provided with gas tube.Two on guiding crossbeam is set; Lay respectively between the long limit of main body inner side-wall, two dividing plates; Guiding crossbeam bottom surface and dividing plate bottom surface are positioned at same plane, and the clearance distance of two guiding crossbeams is less than fermentation railway carriage or compartment width, and the clearance distance of guiding crossbeam and transmission mechanism should be greater than fermentation railway carriage or compartment height.The digestive organ lower body part is a proving room; The proving room bottom is provided with transmission mechanism; Transmission mechanism adopts the stepped start-stop system type of drive; Its every transmission once drives the travel forward distance of position, a railway carriage or compartment of fermentation railway carriage or compartment, and the timed interval equals the fermentation period and the ratio of digestive organ to the design hold-up in the railway carriage or compartment of fermenting of material.The every transmission of transmission mechanism is once accomplished a charging and discharging to digestive organ simultaneously.
The fermentation railway carriage or compartment that stalk cut growth strip, layering are packed into and conformed to feed gap dimension, the railway carriage or compartment wall in fermentation railway carriage or compartment is netted.The fermentation railway carriage or compartment that installs stalk gets into digestive organ by the timed interval by the opening for feed order.Guiding crossbeam and bottom transmission mechanism acting in conjunction make the fermentation railway carriage or compartment fixing in vertical direction, and are immersed in the fermented liquid fully; In the horizontal direction, the fermentation railway carriage or compartment is under transmission mechanism drives, to discharge port direction sequential advancement.Wall contacts with stalk fermented liquid through netted railway carriage or compartment, anaerobic digestion methane production, and the biogas of generation gets into gas dome, derives through gas tube.The fermentation of the fermentation period in fermentation railway carriage or compartment arrives discharge port, whole railway carriage or compartment discharging, and fermentation remaining solid material is stayed in the fermentation railway carriage or compartment, and liquid return is to proving room.
Stalk is packed into behind the fermentation railway carriage or compartment, and order gets into digestive organ and carries out anaerobic digestion, can make input and output material smooth and easy; Digestive organ aerogenesis distributing equilibrium, fermentation efficiency improve, and need not simultaneously stalk such as is pulverized at complicated pre-treatment; Effectively avoid fermentation materials come-up crust, the operation power consumption is few.
