Description
Technical field
The present invention relates to environmental protection equipment technologies more particularly to a kind of sludge high temperature aerobic fermentation for closing fermentation process to set
It is standby.
Background technique
In 80% sludge fermentation technology of moisture content currently on the market, it is generally adopted by trough composting and ferments, is strip style
Compost fermentation or common fermentation tank.
Trough composting fermentation be by sludge and auxiliary material (mushroom residue, sawdust, stalk, house refuse etc. are other) and back mixing material,
It is transported in the ground or underground tank of fermentation plant after mixing according to a certain percentage with dumper or forklift and carries out aerobic fermentation, sent out
It using turner or turns over the machine that pushes away and carries out periodically turning over throwing during ferment.
Strip style compost fermentation is by sludge and auxiliary material (mushroom residue, sawdust, stalk, house refuse etc. are other) and back mixing
Material is transported to fermentation plant or open area with dumper or forklift after mixing according to a certain percentage and stacks hair with long strips
Ferment, the same of no oxygen system push away oxygen supply using regular turn over, and ferment tank is by sludge and microbial inoculum, mushroom residue and back mixing material
It is transported to and is promoted in hopper with forklift after mixing according to a certain percentage, sludge is sent into tank deck feeding inlet by promotion hopper and is then fallen
Enter and carries out aerobic fermentation in tank body.
Since back mixing material and mushroom must be all added in the sludge that sludge components characteristic and the unusual needs of organic matter height ferment
Mushroom slag, sawdust, stalk, house refuse etc. are other, in the market the dirt of some sludge fermentation disposition received moisture content 80% in center
Mud, it is general still to use trough composting and strip style composting process, it needs to be arranged more turners, overthrow machine.
The requirement of moisture content general for sludge fermentation technique, needs moisture control between 55%-65%, in addition
Since the sludge of moisture content 80% is extremely low at paste air penetrability, so by the dirt of a large amount of auxiliary material or back mixing material and required fermentation
Mud mixing.Since various regions sludge organic matter and moisture content are different, some add auxiliary material and back mixing material and 80% sludge ratio is 1 ratio
1,1 to 1.5,1 to 2, some areas 1 to 3 are mixed, and reach moisture content, carbon-nitrogen ratio needed for sludge fermentation and organic substance energy
Amount.
Moisture content 30%, 35%, 40% will be obtained after the sludge fermentation of 80% moisture content, according to law of conservation of energy by 1
Ton 80% sludge fermentation of moisture content is gone to moisture content 40% according to the constant 1* of amount of solid (1-80)=0.2/ (1-40%)=0.33
1-0.33=0.67 tons of water of the moisture content removed.So the energy of partial sludge itself is insufficient, cannot be reached in the fermentation period of anticipation
It to ideal effect, and then needs to increase auxiliary material, so the practical main function of back mixing material is mixed with the sludge of moisture content 80%
Afterwards, moisture content needed for fermenting is reduced；It on the other hand is part microbial bacteria Returning utilization culture, and trough composting ferments and item
The height of materials of pile formula compost fermentation is all restricted, the reason is that bottom aeration it is material bed too thick cannot otherwise will affect fermentation,
1.5 meters are generally not more than substantially all at 0.6-0.8 meters, are calculated by 100 tons of 80% sludge of moisture content of small-scale fermentation process daily, it is dirty
Mud and auxiliary material occupied area are too big, and occupied area and cost of investment are excessively high, and foul smell is difficult to collect, due to the complicated composition of sludge itself
With the smell generated in fermentation process, cause environmental pollution serious, it is also very big to operative employee's personal injury.
And trough composting fermentation and strip style compost fermentation space it is too big, complete deodorization qualified discharge it is at high cost from
Spectrum, majority to naturally drain atmosphere, only furnish having mating deodorization by some projects, because one ton of sludge of fermentation is per small
When required air quantity about 110m3Air partial air give aerobic microbiological absorb, most of air be for taking away moisture, and
Turning over throwing is frequently not that substantially uniformity causes the material of the not decomposed fermentation of part finished product material appearance to have big blocky and graininess etc., part
Not decomposed organic materials is directly dried and is granulated by enterprise, and then affects the quality of organic matter fermentation material.
Fermentor principle and technology are resell after being derived from Germany to Japan, and Some Domestic producer was drawn by 2013 from Japan
Into fermentor is used for the fermentation of feces of livestock and poultry, kitchen garbage in Japan, and imitative do of individual producers one to one is used as sludge hair
There is a series of problems, such as the fracture of rabbling mechanism main shaft, blade fracture, driving machine cudrania cochinchinensis during fermented sludge in ferment
Gear teeth fracture, the uneven internal landslide of discharging, cannot normally discharge and the unstable always frequent culture bacterium bed of yield at main shaft key fracture
Furnace lifting causes sludge fermentation tank can not operate normally, and place out of the ordinary reduces resistance and the increasing of driving mechanism using a large amount of auxiliary material
Add the gas permeability of sludge but the yield fermented is according to feces of livestock and poultry and kitchen garbage reduces 70% or more and also unstable,
The reason is that the design of fermentor itself principle, design parameter, mechanics is the substance according to feces of livestock and poultry and kitchen garbage, feces of livestock and poultry
And the specific gravity of kitchen garbage, sponginess, air penetrability, composition, required oxygen amount and municipal sludge are entirely different, so cannot without exception and
