Abstract
The present invention relates to a kind of application of active carbon layer in the waste gas pollution control and treatment of pig farm, the Char Residues Structure is among two layers of mesh, accumulation filling active carbon particle, excrement is discarded using pig factory and prepares active carbon, and the active carbon particle that pattern is completed and has some strength is obtained by prilling and stoving process；Active carbon particle is effectively accumulated again, is placed in indoor environment and carries out circulation absorption, exhaust gas such as amino, hydrogen sulfide in pig farm is adsorbed, removes most of pernicious gas, drops influence of the low exhaust gas emission to environment.The present invention reduces the discharges of pollutant, improve the resource utilization during pig-breeding.
Description
Technical field
The invention belongs to pig-breeding field of environmental technology, more particularly to utilize the active carbon of pig manure preparation in breeding process
Layer material.
Background technique
Live pig is the maximum breed variety of animal husbandry, and the specific gravity that the live pig amount of delivering for sale accounts for the national always amount of delivering for sale reaches 92.06%,
China's live pig localization of production is laid out to be formed, and advantage producing region is prominent.With the increase of animal husbandry environmental protection pressure, many livestock and poultry
Field increasingly wishes that fecaluria can decompose in livestock and poultry farm with regard to carrying out consumption completely, avoids waste outlet and leak to cause environment
Harm.
Excrement, sewage, foul gas and the pollutants such as live pig corpse of dying of illness generated during pig-breeding, without nothing
Evilization processing is directly discharged into environment, will seriously pollute to generations such as water body, air, soil.Due to the density of Pig breeding
It is higher, the toxic and harmful gas, powder such as hydrogen sulfide, ammonium hydroxide that live pig excrement generates under microbial action after excreting
It, can be with atmospheric propagation and diffusion after dirt, pathogenic microorganism etc. are discharged into atmosphere.
Active carbon is most important material in treating tail gas, is applied to absorption dimethylbenzene, NO at presentx、CO2Equal gas
Body, or it is used as vehicle exhaust desulfurizing agent.Using the absorption and De contamination principle of active carbon, pig farm exhaust gas low cost can be used as
The optimal selection of circulation treatment.
In order to reduce the environmental pollution in pig-breeding, active carbon is prepared using the pig manure that live pig factory generates, for reducing
Pig farm exhaust gas discharges the pollution to environment, realizes the development of efficient green aquaculture industry, the present invention provides a kind of active carbons
Material.
Summary of the invention
In order to solve the above technical problems, the answering in the waste gas pollution control and treatment of pig farm the present invention provides a kind of absorbent charcoal material
With.
The present invention is achieved by the following technical programs.
The present invention provides a kind of application of active carbon layer in the waste gas pollution control and treatment of pig farm, it is characterised in that:
Activated carbon layer is placed in the waste gas treatment device of pig farm, the active carbon layer structure is the heap among two layers of mesh
Product filling active carbon particle, the accumulation mode are that the direction that active carbon particle prolongs perpendicular to net is filled out in the way of layer heap product
It fills, the layer heap product is the superposition multilayer that grain diameter is gradually increased or the multilayer that grain diameter size is overlapped mutually；
The preparation step of the active carbon includes:
1. the swine excrement soaking fermentation 12-36h that will be collected during intensive culture；
2. adjusting dejecta moisture, addition bentonite, kaolin, clay, concave convex rod adjust stool consistency, make it easily
Grain；
3. soft grain granulation: by step, 2. treated that excrement directly uses soft grain granulation machine granulation formation,
4. heat treatment: the above-mentioned soft particle being granulated into being carried out heat treatment process, active carbon particle material is made；
5. screening: 4. granular materials that step is obtained obtains the active carbon particle of certain partial size by screening machine.
The net is metal mesh, plastic wire, to the supporting layer as absorbent charcoal material, and due to having centainly strong
Degree and flexibility, feature easy to process can be used as the carrier layer of wastewater and waste gas treatment device.For example, the metal mesh is
Stainless (steel) wire or wire netting, the plastic wire are carbon fibre web or plastic fiber net.
The accumulation mode is that the direction that active carbon particle prolongs perpendicular to net is filled in the way of layer heap product, the layer heap
Product is the multilayer that the superposition multilayer that grain diameter is gradually increased or grain diameter size are overlapped mutually.Efficiently accumulation is to realize to have
The key of toxic and harmful gas, heavy metal, organic matter in effect absorption waste water and exhaust gas.
The particle size range of the active carbon is 0.01mm-10mm.Ulking thickness is 1-100mm.
The mode for adjusting dejecta moisture be the excrement that will have been cleaned add water or be dehydrated make dejecta moisture up to 10~
70% (weight percent).
The heat treatment process is first to air-dry 1-12h at 0-30 DEG C finally to exist then in 40-80 DEG C of heating 1-12h
120-200 DEG C of drying 1-12h is basically unchanged granule-morphology after drying.
The purpose of heat treatment is after drying pig manure particle, and wherein organic matter is gradually carbonized, and keeps the pattern of particle,
It does not crush.
80.1% is organic matter in the dry matter of pig manure, and easy decomposability organic C is 27.3%, hemicellulose and cellulose
Content is lower, and the content of crude fat and lignin is higher, than conveniently as the source of active carbon.
Contain bulk gas in pig manure after fermentation, form porous structure after granulating and drying, this is dirty for activated carbon adsorption
Aqueous medium provides good carrier；Active carbon table due to content of organic matter accounting nearly 1/3 in pig manure, after calcining drying
Area is larger, is very suitable for adsorbed gas processing.The present invention obtains pattern by prilling and completes and with certain strong
The pig manure particle of degree, by high-temperature heating, particle carbonization.The adjustable different faecal pellets of partial size can be obtained by being granulated.
The present invention has manufactured certain structural strength and suction by the stratum reticulare with some strength by efficiently accumulation mode
The active carbon layer of attached performance, the layer of charcoal not only can be adapted for the discharge for reducing polluted gas, also improve pig-breeding mistake
Resource utilization in journey.
