Description
[technical field]
The utility model relates to the air feeder technical field, particularly relates to a kind of air feeder of fermentation cabin.
[background technology]
Along with developing rapidly of urbanization, the generation of organic solid castoffs such as city sewage and sludge, feces of livestock and poultry also increases thereupon.At present, generally all adopt the mode of compost to handle these organic solid castoffs.Composting process is meant that organic waste change into stable soil ulmin process under action of microorganisms, and composting process has two kinds of aerobic compost and anaerobic compostings, and the utility model is fit to aerobic compost.
Aerobic composting process be organism under the condition of aerobic, make good use of the secreted exoenzyme of oxygen animalcule organic solid waste be decomposed into dissolved organic matter matter, penetrate in the cell again.Microorganism is by Metabolic activity, and a part of oxidation operation is wherein become simple inorganics, and for biological vital movement provides required energy, another part organism is converted into the required nutritive substance of organism, forms new cell paste, and microorganism is constantly bred.Generally all be to force to supply air in the windrow during microbial fermentation.General plenum system is that several parallelpiped cloth are in the windrow layer, every pipeline independent separately or whenever with pipeline separately separate connection on a total pipeline, when the air blast of windrow bottom, air is entered by the windrow bottom, shed by the windrow surface, air is delivered to the top layer very soon with the heat of windrow inside, and the top layer heat-up rate is fast, innoxious degree is good, but waste gas easily collecting not.
[utility model content]
The utility model provides a kind of device of the foul smell that can produce in order to overcome existing issue when even air feed of windrow and collection fermentation.
To achieve these goals, design a kind of air feeder of fermentation cabin, the top that it is characterized in that fermentation cabin is provided with the gas sampling device, adopt column to be connected between fermentation cabin and the gas sampling device, the middle and upper part of gas sampling device inner chamber is provided with gas drier, the gas sampling bottom of device is provided with the hydrogen sulfide monitoring device, annular air supply line one end connects the bottom of fermentation cabin, the annular air supply line the other end connects the central top of gas sampling device, the bottom and the top of annular air supply line are provided with Self controlling valve, the oxygen level monitor is located at the ingress of air supply line and fermentation cabin, and monitoring infeeds the oxygen content in the windrow gas;
Described gas sampling device is a rectangular pyramid shape;
Siccative in the described gas drier can be reused;
Described ducted valve is regulated size or auto-switch automatically according to the data that oxygen level automonitor and hydrogen sulfide monitoring device monitor.
The utility model is compared with prior art, operating process level of automation height, technology is simple, two valves can according to monitor data auto-switch or regulate the size of air input, dehumidification system can effectively absorb the water vapour in the foul smell, prevent the equipment in the gaseous corrosion air supply device, the annular steam line, make the gas enter pipeline can be fed to each corner of windrow uniformly, and can make the generation of the phenomenon that air outlet air pressure can not reduce along with the increase of distance blower fan distance.
[description of drawings]
Fig. 1. be the utility model structural representation;
Fig. 2. be the utility model annular air supply line structural representation.
Among Fig. 11 is the gas sampling device, and 2 is gas drier, and 3 is the hydrogen sulfide monitoring device, and 4 is the oxygen level automonitor, and 5 is Self controlling valve, and 6 is air supply device, and 7 is fermentation cabin; Among Fig. 2 21 is annular air supply line.
[specific embodiment]
1,2 the utility model will be further described in conjunction with the accompanying drawings:
A kind of air feeder of fermentation cabin, the top of fermentation cabin is provided with the gas sampling device, the gas sampling device is a rectangular pyramid shape, adopt column to be connected between fermentation cabin and the gas sampling device, the middle and upper part of gas sampling device inner chamber is provided with gas drier, siccative can be reused, the gas sampling bottom of device is provided with the hydrogen sulfide monitoring device, annular air supply line one end connects the bottom of fermentation cabin, the annular air supply line the other end connects the central top of gas sampling device, the bottom and the top of annular air supply line are provided with Self controlling valve, described ducted valve is regulated size or auto-switch automatically according to the data that oxygen level automonitor and hydrogen sulfide monitoring device monitor, the oxygen level monitor is located at the ingress of air supply line and fermentation cabin, and monitoring infeeds the oxygen content in the windrow gas.
The utility model when work, after fresh windrow enters fermentation cabin, close gas drier in ventilator trunk, to the windrow air feed, gas is fed in the windrow uniformly through circulating line by the external world.When material ferments after to a certain degree, must there be foul smell to produce, foul smell is mainly hydrogen sulfide, when the hydrogen sulfide monitoring device monitors gas concentration above set(ting)value, ducted valve is opened automatically, enters pipeline behind the foul smell drying device, is fed in the windrow again.Simultaneously, the oxygen level automonitor, can according to monitor data, regulate the ratio of foul smell amount and extraneous air input, the assurance fermentation efficiency forms a good recycle system.
After windrow cloth in fermentation cabin is good, want the ducted valve open that is communicated with the external world, gas is fed in the windrow by annular steam line.
Material is through after a while fermentation, after the content of hydrogen sulfide in the foul smell that produces surpasses normality, and two valve opens in the foul smell collection device, the foul smell of generation is fed in the windrow again through gas drier.
The oxygen level automonitor, can according to monitor data, regulate the ratio of foul smell amount and extraneous air input, the assurance fermentation efficiency forms a good recycle system.
