Abstract
The invention discloses novel anaerobic fermentation equipment and method for sludge. The equipment and the method are used for solving the problems of the existing anaerobic fermentation equipment for the sludge during sludge fermentation that the stirring is nonuniform, the stirring effect is poor, the sludge fermentation rate is low, the work efficiency is low, and biogases generated from the sludge fermentation cannot be exhausted from the sludge promptly. According to the equipment and the method, a stirring shaft moves downwards while carrying out stirring, so that the sludge stirring effect is greatly improved, and the stirring of the sludge is more uniform. The stirring shaft carries out rotary stirring intermittently, so that the reduction of stirring resistance is facilitated, and the phenomenon of jamming is prevented. Wedge-shaped convex ribs on a rotating table and butting convex ribs on the external bottom surface of a fermentation drum are in butted fit so as to regularly dither the fermentation drum while carrying out stirring on the sludge, thus, on one hand, the stirred sludge can be prevented from overflowing from the fermentation drum, on the other hand, the sludge is vibrated, and the timely discharge of the gases from the sludge is facilitated.
Description
Technical field
The present invention relates to a kind of Zymolysis Equipment, more specifically, it relates to a kind of novel sludge anaerobic Zymolysis Equipment and method.
Background technology
At present, China processes organic sludge, the method for house refuse and is mainly and traditional fills up, burn, push away fertilizer etc., soil, subsoil water and air are worked the mischief by these methods to a certain extent, and resource reproducible in organic sludge or house refuse can not be utilized, cause the waste of resource.For municipal sludge, existing frequently-used method is by anaerobic fermentation, mixes with mud in pond, be then stirred anaerobic fermentation in primary sludge is sent into fermentation vat, obtains methane fuel, and the mud after decomposing is discharged in pond.But currently used a lot of sludge anaerobic Zymolysis Equipment stir inequality during sludge fermentation, and mixing effect is poor, sludge fermentation speed is slow, inefficiency, and the biogas that sludge fermentation produces can not be discharged in time from mud.
Summary of the invention
Instant invention overcomes existing sludge anaerobic Zymolysis Equipment during sludge fermentation, stir inequality, mixing effect is poor, sludge fermentation speed is slow, inefficiency, and the deficiency that the biogas of sludge fermentation generation can not be discharged in time from mud, provide a kind of novel sludge anaerobic Zymolysis Equipment and method, it makes mud stir during the fermentation, mixing effect is good, sludge fermentation speed is fast, work efficiency is high, and the biogas that sludge fermentation produces can be discharged in time from mud, is conducive to improving fermenting speed and ferment effect.
In order to solve above-mentioned technical problem, the present invention is by the following technical solutions: a kind of novel sludge anaerobic Zymolysis Equipment, including fermentation tank, fermentation cylinder it is socketed with in fermentation tank, fermentation tank inner bottom surface is provided with rotating disk, disk upper surface is laid with the wedge shape raised line of some arcs, wedge shape raised line upper surface is inclined upwardly setting clockwise, it is provided with the abutting raised line of some arcs on fermentation cylinder outer bottom with wedge shape raised line one_to_one corresponding adaptation, abuts raised line lower surface along counterclockwise downward-sloping setting；Support is installed on fermentation tank, it is provided with shaft in fermentation cylinder, shaft lower end connects stirring vane, shaft upper end can slide axially and radially stop collar is connected to ratchet, on shaft, above ratchet, movable sleeve is connected to pushing disk, on shaft, pushing disk connection fixed above has shake dish, the voussoir of several arcs it is laid with on pushing disk upper surface, voussoir upper surface is inclined upwardly setting clockwise, it is provided with the abutting block of several arcs with voussoir one_to_one corresponding adaptation on shake dish lower surface, abut block lower surface along counterclockwise downward-sloping setting, between shake dish upper surface and support, abutting spring is installed, catch bar is connected on pushing disk, connect on catch bar and have the ratchet adaptive with ratchet, the stirring motor driving pushing disk to rotate is installed on support.
During sludge fermentation, the first step, primary sludge is poured in fermentation cylinder from fermentation tank top, mixes with the mud of residual in fermentation cylinder；Second step, starts stirring motor, drives pushing disk to rotate and realizes the stirring of shaft intermittent rotary, stirring motor drives pushing disk to rotate forward ratchet and drives pawl wheel, thus drive shaft to rotate and mud in fermentation cylinder is stirred, meanwhile, shaft moves down；Stirring motor drives pushing disk reversion ratchet return, and shaft stops operating, and meanwhile, shaft moves up return；3rd step, repeats second step action, and periodically rotates rotating disk, is shaken up and down by fermentation cylinder by the cooperation of wedge shape raised line and abutting raised line；Blast in fermentation cylinder in mud after gas heating in periodically extraction fermentation cylinder；4th step, after mud complete fermentation decomposes, collects the biogas produced, and discharges the interior mud fermented of fermentation cylinder.Shaft moves down while stirring, considerably increases the mixing effect of mud, and the stirring making mud is more uniform.Owing to during sludge agitation, resistance is relatively big, shaft intermittence rotates stirring, is conducive to reducing stirring resistance, prevents the phenomenon of clamping stagnation.Periodically shake fermentation cylinder is coordinated to being abutted by the abutting raised line on the wedge shape raised line on rotating disk and fermentation cylinder outer bottom while sludge agitation, on the one hand the mud being prevented from stirring overflows fermentation cylinder, on the other hand vibrating mud, the beneficially gas in mud is discharged in time.This novel sludge anaerobic Zymolysis Equipment makes mud stir during the fermentation, mixing effect is good, and sludge fermentation speed is fast, and work efficiency is high, and the biogas that sludge fermentation produces can be discharged in time from mud, is conducive to improving fermenting speed and ferment effect.
