Description
Technical field
The utility model belongs to environmental protection and field of renewable energy, is specifically related to a kind of pig farm bubble manure pit.
Background technology
The reset mode of scale pig farm fecaluria has dry clear excrement, water rushes several technique such as clear excrement, bubble excrement.Dry clear excrement mainly manually does clear excrement in the past, and by hand sweeping by outside ight soil removing house, pig urine is by gravity flow discharge, and advantage is easy and simple to handle, need not be mechanical, and not power consumption is few with water, invests low; Shortcoming is that the amount of labour is large, and efficiency is low.Because manually the dry clear excrement amount of labour is large, many pig farms start to adopt mechanical dung scraping plate to carry out dry clear excrement, technique relative complex, and operation easier is comparatively large, needs power consumption, difficult in maintenance after breaking down.It is utilize current to be flushed to outside house by fecaluria that water rushes clear excrement, drains into septic tank or biogas generating pit through slurry gutte.Common mode has that shower nozzle water rushes clear excrement, bar gate type water rushes clear excrement and self-flowing type water rushes several mode of clear excrement.Its advantage is that equipment is simple, and efficiency is high, and fault is few, is conducive to pig house health, is easy to control epidemic disease and infects; Shortcoming is that capital expenditure is large, and waste water treatment engineering is large, and water consumption is many.The clear excrement technique of bubble excrement divides into bubble manure pit at pig house slatted floor, a certain amount of water is injected in pond, fecaluria, flushing and feeding and management water enter in the underfloor bubble manure pit in gap in the lump, after storage certain hour (being generally 1 ~ 2 month), after bubble manure pit is filled, open the gate of outlet, liquid dung in pond is discharged.Liquid dung flows into ight soil trunk ditch, enters manure storage pond, underground or is drawn into manure storage pond, ground with pump.Its advantage is
:save artificial, conserve water.Shortcoming is: fecaluria steeps manure pit for a long time and stops under crack base plate, and biogas fermentation occurs, and produces a large amount of harmful and foul gas, as H
2s(hydrogen sulphide), CH
4(methane), volatile organic matter (VOC) etc., jeopardize the health of animal and keeper.Harmful and foul gas is discharged outside house, pollutant atmosphere.Meanwhile, the methane that bubble manure pit produces, is not only flammable explosive gas, gathers explosion limit at pig house, easily set off an explosion, fire incident; And be greenhouse gases, its greenhouse effect are CO
221 times, global climate is impacted.In addition, in the excrement dirt that bubble manure pit is discharged, organic concentration is very high, but when carrying out biogas fermentation process to it, biogas yield is but very low, is unfavorable for that methane recovery utilizes.
Summary of the invention
The purpose of this utility model there is technical barrier that is harmful and foul gas contaminated environment to solve existing pig farm bubble manure pit, for people provide one can collect biogas, harmful and foul gas, alleviates the pig farm bubble manure pit of environmental pollution.
The purpose of this utility model is realized by following proposal.
Pig farm of the present utility model bubble manure pit, it is characterized in that bubble manure pit top, described pig farm is crevice board, crevice board divides into bubble manure pit, and two-layer gas skirt is established on bubble manure pit top, leaves gap and mutually hide between upper gas skirt and lower gas skirt; Gas exhaust outlet is established at gas skirt top, and gas exhaust outlet and gas are discharged supervisor and is connected; Blow down branch is established in bubble manure pit middle and upper part, and blow down branch and blowdown are responsible for and are connected; Pollution discharge sluise gate is established bottom bubble manure pit.
In such scheme, described gas skirt is that accumbency is triangular prism shaped, and triangular prism end face and bottom surface are closed, and the side towards bubble manure pit is opened wide.
Piggery waste is collected by the utility model, store and treatment facility is integrated in one, and both can collect and store excrement dirt, can carry out biogas fermentation again.
The utility model utilizes gas skirt to collect the biogas of bubble manure pit generation, harmful and foul gas, can greatly reduce harmful in pig house and foul gas content, and then can reduce pig house ventilation and energy consumption.Biogas, harmful and foul gas that gas skirt is collected not only can reclaim the energy by burning, and pernicious gas can be made innoxious, eliminate stench, reduce foul smell to the impact of nearby residents.The biogas of bubble manure pit generation is collected, the blast that methane can be avoided to cause and fire incident by gas skirt.No longer can build outward biogas fermentation facility at pig house, investment reduction.
In sum, the utility model solves existing pig farm bubble manure pit and there is technical barrier that is harmful and foul gas contaminated environment, and the pig farm bubble manure pit provided for people can collect biogas, harmful and foul gas, alleviates environmental pollution.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1. crevice board; 2. steep manure pit; 3. go up gas skirt; 4. descend gas skirt; 5. gas exhaust outlet; 6. gas discharges supervisor; 7. blow down branch; 8. blowdown supervisor; 9. Pollution discharge sluise gate; 10. manure pit liquid level.
Embodiment
Further describe the utility model below by embodiment, the utility model is not limited only to described embodiment.
Embodiment one
