Abstract

The utility model relates to an aerobic fermentation facility of organic waste, which comprises that a semi-underground fermenter (5) with two open ends is arranged in a solar greenhouse shed (1) with good lighting, ventilation and heat insulation effects. A mixed material (2) is positioned in the fermenter; the bottom (5) of the fermenter (5) is provided with a high-pressure ventilation system (3); and two winterproof channels (6) are arranged on two sides outside the greenhouse shed (1) in parallel along the axial direction of the fermenter (5).

Description

Organic waste aerobic fermentation facility

Technical field:

The utility model relates to a kind of organic waste aerobic fermentation facility.

Background technology:

For making solid organic castoffs such as life in the countryside rubbish, stalk obtain harmless treatment and recycling, generally adopt aerobic fermentation process to handle.Aerobic fermentation is meant organic materialss such as domestic refuse, stalk, human and animal excreta, under suitable conditions such as temperature, moisture, carbon nitrogen ratio and competent oxygen, make good use of oxygen animalcule and make organic matter degradation and kill harmful germ, reach the technological process of harmless treatment requirement.When 30 ℃ of left and right sides of envrionment temperature, aerobic fermentation starts the fastest, and microorganism growth is vigorous; Temperature is low more, and microorganism growth speed is slower, until stopping growing.At present, solid organic castoffs such as north cold area employing aerobic fermentation process processing domestic refuse, stalk, heating measures such as palpus employing fire coal move continuously with the assurance fermentation installation, problems such as existence is invested greatly, running cost height.The utility model belongs to the cultural solid reclaiming organic waste and utilizes technology, this technology does not adopt conventional energy resourcess such as fire coal, electric power, makes full use of sun power, biological fermentation energy, and adopt insulation temperature increasing facility such as winter protection ditch, purpose is to provide a kind of have less energy-consumption, low operating cost characteristics, and the aerobic fermentation facility of northern area sustainable operation in winter.

The utility model content:

In the respond well solar energy greenhouse booth of ventilating and thermal insulating, have the semi-underground type fermenter that two ends open wide, place the mixture of the domestic refuse, stalk and the feces of livestock and poultry that are mixed with macrobead flexible material (as block corn stalk etc.) in the groove, 1.5～1.8 meters of mixture bed depth; Utilize the submerged fermentation material as heat-absorbing medium, absorb, store sun power; Both sides warmhouse booth outside simultaneously are filled with two winter protection ditches of lagging materials such as sawdust, stalk along the parallel construction of fermenter axis direction, and the fermentation materials heat is to external diffusion when preventing night temperature reduction.This fermentation installation is not having under fire coal or the electric power heating state, provide aerobic fermentation required envrionment temperature, organic materials is fermented smoothly, solved the problem that conventional fermentation installation need adopt fire coal or electric power heating, temperature keeping, significantly reduced facility investment and running cost.In the fermenter bottom high pressure ventilation system is set, utilizes the macrobead flexible material to increase the fermentation materials porosity, reduce ventilation resistance, compare, can significantly improve drafting efficiency, cut down the consumption of energy with existing method of ventilation.

Advantage of the present utility model and positively effect:

1, fermentation materials is absorbed solar heat as heat-absorbing medium, and utilize the heat insulation function of semi-underground type fermenter, deep layer material and winter protection ditch, there not being the outside to heat under the situation of measure, solved the difficult problem that cold district aerobic fermentation facility is difficult to normal operation winter;

2, make full use of sun power, bioenergy, save energy has reduced domestic refuse, agricultural crop straw the like waste harmless treatment cost, has promoted the waste material recycle;

3, adopt the macrobead flexible material as weighting material,, compare, can improve drafting efficiency, reduce operation energy consumption with existing method of ventilation to increase the voidage of fermentation materials.

Embodiment:

In the respond well solar energy greenhouse booth 1 of ventilating and thermal insulating, the turnover of material for convenience, have the semi-underground type fermenter 5 that two ends open wide, organic wastes such as domestic refuse, stalk and feces of livestock and poultry and macrobead flexible material 4 (as block corn stalk etc.) mixed form mixture 2, enter fermenter 5 from an end of facility and carry out aerobic fermentation, the mixture bed depth remains on 1.5～1.8 meters.In order to make the aerobic fermentation process not moved continuously by the influence of region and temperature Change, this utility model utilizes the submerged fermentation material as heat-absorbing medium, absorbs, stores sun power; Both sides warmhouse booth 1 outside simultaneously, along two winter protection ditches 6 that are filled with lagging materials such as sawdust, stalk of the parallel construction of fermenter 5 axis directions, the fermentation materials heat is to external diffusion when preventing night temperature reduction; And high pressure ventilation system 3 is set in fermenter 5 bottoms, regularly give fermentation materials air blast, the required oxygen of afterfermentation; Mixture through about 35 days aerobic fermentation after, produce organic fertilizer, reached harmless treatment.The organic fertilizer that the ferments the other end from facility is transported, be used for agriculture production, realized the recycling of organic waste.

Claims

1, a kind of organic waste aerobic fermentation facility, it is characterized in that: in the good solar energy greenhouse booth (1) of daylighting, insulation, performance of ventilating, have the semi-underground type fermenter (5) that two ends open wide, place the fermentation materials bed depth in the groove and reach 1.5 meters-1.8 meters mixture (2), in fermenter (5) bottom high pressure ventilation system (3) is set, both sides outside warmhouse booth (1) are along fermenter (5) axis direction two winter protection ditches of parallel construction (6).
