Abstract

The invention discloses a peristaltic anaerobic solid-state fermentation device used for methane fermentation. The invention is characterized in that four rows of stub groups are symmetrically fixed in the device; and springs in the stubs can be driven by an electromagnetic device for driving the stubs to do flexible reciprocating motion along the horizontal direction, so as to strengthen the peristalsis of the solid-state material in a reactor, thereby being beneficial for mass and heat transfer of the material, avoiding partial acidification, being beneficial for overflow of methane and being favorable for improving the system stability and the methane yield.

Description

A kind of creeping motion type is used for the anaerobic solid-state fermentation device of biogas fermentation
[technical field]
The invention belongs to the biogas fermentation field, specially refer to the device of creeping type anaerobic solid-state fermentation biogas.
[background technology]
In energy today in short supply day by day, biogas is as a kind of geseous fuel, not only can replenish the vacancy that fossil oil reduces, also can solve the problem of environmental pollution of agricultural wastes, daily life rubbish, industrial waste etc. simultaneously, therefore the production of biogas not only has an economic benefit but also ecological benefits are arranged, and is worth developing energetically and promoting.
At present an important directions of biogas development is exactly a sludge gas dry fermentation, compare with traditional liquid state fermentation, anaerobic solid-state fermentation have water saving, energy-conservation, technology simple, little, the low cost and other advantages of pollution.But there is its technical bottleneck in the anaerobic solid-state fermentation technology of biogas; as conduct heat, mass transfer is unequal, at present, its solution adopts the mode of stirring to increase the motion of material more; but be applicable to the whipping appts of liquid fermenting material mostly; in solid substances, difficult stirring, energy consumption height; weak effect; and the shearing force that stirs also can work the mischief to the growth of thalline, be unfavorable for the steady running of anaerobic solid-state fermentation, therefore limited the large-scale development that anaerobic solid-state fermentation produces biogas technology.
[summary of the invention]
At the problem that exists in the above-mentioned solid state fermentation firedamp gas equipment, the present invention simulates the principle of gastrointestinal peristalsis, developed device by wriggling reinforced anaerobic solid state fermentation biogas process, its feature is as follows: the creeping type anaerobic solid-state fermentation firedamp gas equipment, comprise tank body, opening for feed, discharge port, venting port, spring, stub, actuating device of the spring, collection and confinement of gases jar etc., be provided with the contractile stub that is vertical arrangement of tool spring assembly in four groups in tank interior, act on spring, make spring drive the stub along continuous straight runs and make stretching motion by electromagnetic actuator device, act on solid substances by the crisscross motion between stub, material in tank is produced extruding, rub effects such as mixing, thereby strengthen the motion of material, the mass transfer of enhanced reactor internal solid material at inside reactor, conduct heat.
The device of the strengthening solid state fermentation biogas that provides according to technical scheme, it is characterized in that: material is entered by opening for feed, and residue is discharged by discharge port after the fermentation ends, and biogas is discharged by venting port, is stored in then in the collection and confinement of gases jar;
The device of the strengthening solid state fermentation biogas that provides according to technical scheme is characterized in that: have four row stubs in the tank body and fix on it, every an angle of 90 degrees row of arranging, every row are made up of 10-20 stub.
The device of the strengthening solid state fermentation biogas that provides according to technical scheme is characterized in that: at equally distributed 4 stubs of the sustained height of tank body, under the drive of spring, act on jar interior material within it, produce extruding, rub effects such as mixing;
The device of the strengthening solid state fermentation biogas that provides according to technical scheme is characterized in that: stub shrinks the back and stretches back length ratio is 1: 2-1: 10;
The device of the strengthening solid state fermentation biogas that provides according to technical scheme is characterized in that: the ratio that stub stretches back length and reactor diameter is 1: 10-1: 100.
[advantage of the present invention]
The present invention produces firedamp gas equipment with existing solid waste and compares, and have following advantage: (1) has strengthened mass transfer, the heat transfer of solid substances; (2) improved the homogeneity of solid substances temperature, humidity, saved whipping appts, energy consumption further reduces; (3) improve the stability of anaerobic solid-state fermentation system operation and the factor of created gase of biogas, shortened the cycle of fermentation simultaneously.

[specific implementation method]
Embodiment 1
To be mixed in proportion through quick-fried pretreated maize straw of vapour and people, animal excrement, and add a certain amount of water, and inoculate and take from the anaerobic sludge of sewage work, mixing is after opening for feed moves in the reactor, and biogas fermentation is carried out in sealing.10 days cycles, temperature is controlled at about 37 ℃, spring drives stub and stretches 1 time every 30min under the drive unit effect, each 1min, being in symmetric two stubs of sustained height when flexible is one group, and organizes alternating action on material with another, and the stub that is in same row is arranged from top to bottom, odd number is one group, and even number is another group, and alternating action is on material.After the fermentation ends, collecting methane is in gas holder, and fermentation residue is discharged from discharge port.
