Description
Technical field
The present invention relates to solid waste disposal field, in particular to a kind of collaboration kitchen garbage receives conveying, cracking and sorting
The solid waste anaerobic digestion device that slurrying, desanding, anaerobic fermentation, grease separation, biogas slurry and biogas residue processing and biogas treatment utilize.
Background technique
Kitchen garbage is most important one kind in food refuse, including generations such as family, school, dining room and catering industries
Food process leftover bits and pieces (food waste) and edible remnants (hogwash).Its complicated component, mainly oil, water, pericarp, vegetables, rice and flour,
The mixture of many kinds of substance such as fish, meat, bone and useless tableware, plastics, paper handkerchief.China's kitchen garbage quantity is very huge, and
In rapid increase trend.
The mainstream processing mode of kitchen garbage has a three categories, and 1) it is directly used as feed；2) pass through anaerobic ferment for methane；3)
Pass through aerobic fermentation fertilizer.Currently, in a manner of the second class i.e. for anaerobic fermentation technology, process flow are as follows: will collect
Kitchen garbage bulk materials are removed by sorting unit first, then mentioned oil and recycle grease therein, and after be beaten, adjusted
Matter, into anaerobic reaction-pot.Material is contacted with strain herein, under conditions of certain pH and C/N ratio, through hydrolysis acidification, methane
Change and generate biogas, goes to generate electricity or directly do fuel after biogas is purified.Biogas slurry does liquid fertilizer or Air Exposure qualified discharge.It is few
It measures biogas residue and solid fertilizer is made through heap.
In aforesaid way, there is also following deficiencies at present for the anaerobic digestion techniques of kitchen garbage: temperature, PH in anaerobic processes
Value, nutriment and substrate toxicity have a large effect to fermentation process, operator constantly to monitor fermentation process, judgement and
Various parameters are adjusted, real time monitoring is difficult to realize.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of anaerobic digestion of kitchen wastes device,
It can monitor pH value in reactor in real time and be regulated and controled, real-time control reactor temperature, while can make reactant and sludge
It is sufficiently mixed, makes to remain anaerobic digestion optimum condition in reactor.
In order to achieve the above object of the invention, the present invention is realized with following technical solution:
A kind of anaerobic digestion device of kitchen garbage, it includes reactor, and sidewall of reactor top connects the straight-through reaction of feed pipe
Bottom in device.Reactor internal upper part is equipped with the gas gathering mask and three phase separator of taper, three phase separator by after separation waste water and
Biogas is not delivered to the water outlet and biogas pipe discharge reactor of top.It is structurally characterized in that it further includes blender temperature control
Device, white lime addition funnel and pH detector processed.The blender is vertically fixed on reactor center, and blender lower part is equipped with exhibition
The stirring blade opened.Temperature controller is placed on reactor inner bottom plating, and white lime addition funnel and pH are connected on reactor outer wall
Detector.
The present invention has the following advantages and beneficial effects: compared with the prior art
1. reactor bottom adds temperature controller, realizes to the real-time control of reactor temperature, be maintained at anaerobic reaction
Optimum temperature improves the utilization efficiency of kitchen garbage.
2. reactor outer wall addition pH detector can monitor pH value in reactor in real time.White lime addition leakage is added simultaneously
Bucket, can control pH value in reactor by way of adding white lime, maintain pH value in reaction and be conducive to methane generation
In level, increase the output capacity of methane.
3. adding blender in reactor, material is sufficiently mixed with sludge in reaction, improves the efficiency of reaction.
Below with reference to pair figure, the present invention will be further described with specific embodiment.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Referring to Fig. 1, the anaerobic digestion device of kitchen garbage of the present invention includes reactor 10.The connection of 10 side wall upper part of reactor
Feed pipe 6 leads directly to bottom in reactor 10.10 internal upper part of reactor is equipped with the gas gathering mask 2 and three phase separator 4 of taper, three-phase separate
From device 4 by after separation waste water and biogas be not delivered to top water outlet 7 and biogas pipe 9 be discharged reactor 10.Reactor 10
Central vertical fixes blender 1, and 1 lower part of blender is equipped with the stirring blade of expansion.Temperature controller 3 is placed in bottom in reactor 10
On plate, 10 outer wall of reactor connects white lime addition funnel 5 and pH detector 8.
When the invention works, pretreated kitchen garbage material is entered in reactor 10 by feed pipe 6 and is carried out with sludge
Anaerobic reaction, blender 1, which carries out work, while anaerobic reaction is sufficiently mixed material with sludge.While being reacted,
Temperature in 3 real-time control reactor 10 of temperature controller, is maintained at its temperature between 37-38 degree, that is, maintains optimum temperature
Under the conditions of carry out.PH value in 8 real-time monitoring reactor 10 of pH detector, while funnel 5 is added by white lime and adds white lime
PH value is adjusted, pH value is made to maintain the range for being conducive to methane output.The waste water and biogas generated after reaction passes through three-phase separate
It is separated from device 4, reactor 10 is discharged through water outlet 7 and biogas pipe 9 respectively.
