Abstract
The anaerobic digestion device of kitchen garbage, is related to solid waste disposal field.The utility model includes reactor, and sidewall of reactor top connection feed pipe leads directly to bottom in reactor.Reactor internal upper part is equipped with the gas gathering mask and three phase separator of taper, and the waste water after separation and biogas are not delivered to three phase separator the water outlet of top and biogas pipe discharges reactor.It is structurally characterized in that it further includes blender temperature controller, white lime addition funnel and pH detectors.The blender is vertically fixed on reactor center, and blender lower part is equipped with the agitating vane of expansion.Temperature controller is placed on reactor inner bottom plating, and white lime addition funnel and pH detectors are connected on reactor outer wall.The utility model can monitor pH value in reactor in real time and be regulated and controled, and control reactor temperature in real time, while can be sufficiently mixed reactant and sludge, make to remain anaerobic digestion optimum condition in reactor.
Description
Technical field
Solid waste disposal field is the utility model is related to, more particularly to a kind of collaboration kitchen garbage receives conveying, crushes
The solid waste anaerobic digestion that sorting slurrying, desanding, anaerobic fermentation, grease separation, biogas slurry and biogas residue processing and biogas treatment utilize
Device.
Background technology
Kitchen garbage is most important one kind in food refuse, including the generation such as family, school, dining room and catering industry
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 major types, and 1）It is directly used as feed；2）Pass through anaerobic ferment for methane；3）
Pass through aerobic fermentation fertilizer.At present, in a manner of the second class i.e. for anaerobic fermentation technology, its technological process is：Come collecting
Kitchen garbage bulk materials are removed by sorting unit first, then recycle grease therein through carrying oil, and after through being beaten, adjusting
Matter, into anaerobic reaction-pot.Material is contacted with strain herein, under conditions of certain pH and C/N ratios, through hydrolysis acidification, methane
Change and produce biogas, go to generate electricity or directly do fuel after biogas is purified.Biogas slurry does liquid fertilizer or Air Exposure qualified discharge.It is few
Solid fertilizer is made through heap in amount biogas residue.
In aforesaid way, the anaerobic digestion techniques of kitchen garbage also have the following disadvantages at present：Temperature, PH in anaerobic processes
Value, nutriment and substrate toxicity have fermentation process a large effect, operating personnel will constantly monitor fermentation process, judge and
Various parameters are adjusted, are difficult to realize real time monitoring.
The content of the invention
For above-mentioned deficiency of the prior art, the purpose of this utility model is to provide a kind of anaerobic digestion of kitchen wastes dress
Put, it can monitor pH value in reactor in real time and be regulated and controled, and control reactor temperature in real time, while can make reactant and dirt
Mud is sufficiently mixed, and makes to remain anaerobic digestion optimum condition in reactor.
In order to reach foregoing invention purpose, the utility model is realized with following technical solution：
The anaerobic digestion device of kitchen garbage, it includes reactor, and sidewall of reactor top connection feed pipe leads directly to reaction
Bottom in device.Reactor internal upper part is equipped with the gas gathering mask and three phase separator of taper, three phase separator by the waste water after separation 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 detectors processed.The blender is vertically fixed on reactor center, and blender lower part is equipped with exhibition
The agitating vane 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 utility model has the following advantages and beneficial effect compared with the prior art：
1. reactor bottom adds temperature controller, realize the real-time control to reactor temperature, protect anaerobic reaction
Hold in optimum temperature, improve the utilization ratio of kitchen garbage.
2. reactor outer wall addition pH detectors can monitor pH value in reactor in real time.White lime addition leakage is added at the same time
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. addition blender in reactor, makes material be sufficiently mixed with sludge, improves the efficiency of reaction in reaction.
The utility model is described further with reference to pair figure and embodiment.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Referring to Fig. 1, the anaerobic digestion device of the utility model kitchen garbage includes reactor 10.10 side wall upper part of reactor
Connection 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, and three
Waste water after separation and biogas are not delivered to phase separator 4 water outlet 7 of top and biogas pipe 9 discharges reactor 10.Reaction
10 central vertical of device fixes blender 1, and 1 lower part of blender is equipped with the agitating vane of expansion.Temperature controller 3 is placed in reactor 10
On inner bottom plating, 10 outer wall of reactor connection white lime addition funnel 5 and pH detectors 8.
During utility model works, pretreated kitchen garbage material is entered by feed pipe 6 in reactor 10 and sludge
Anaerobic reaction is carried out, blender 1, which carries out work, while anaerobic reaction makes material be sufficiently mixed with sludge.It is same what is reacted
When, temperature controller 3 controls temperature in reactor 10 in real time, its temperature is maintained between 37-38 degree, that is, maintains optimal temperature
Carried out under the conditions of degree.PH detectors 8 monitor pH value in reactor 10 in real time, while add funnel 5 by white lime and add ripe stone
Ash adjusts pH value, pH value is maintained the scope for being conducive to methane output.The waste water and biogas produced after reaction passes through three-phase
Separator 4 separates, and discharges reactor 10 through water outlet 7 and biogas pipe 9 respectively.
