Description
Technical field
The present invention relates to fermentation equipment technical field, more specifically, relate to a kind of Air suction net and adopt the negative pressure fermentation steam gathering system of this structure.
Background technology
In aerobic fermentation process, after air (oxygen) is passed into fermenting mixture material, under suitable C/N ratio, moisture and microbial process, fermenting mixture material produces fermentation, the temperature of material can reach more than 50 DEG C, the heat that fermentation produces, by the moisture evaporation in fermenting mixture, is discharged outside fermenting mixture windrow.
But methane, carbonic acid gas, hydrogen sulfide, micro-ammonia and some other small molecular organic acid etc. that fermentation produces by moisture evaporation are taken out of in the lump and are evaporate in air, produce topsoil, and the moisture not easily collecting of volatilization, adverse influence is produced to environment.
Especially the atmosphere polluting problem produced in organic waste disposal process is day by day serious.At present, growing industrial and agricultural production brings larger waste treatment problem, and such as, tailing etc. in a large amount of mud of a large amount of stalk that agricultural planting industry is produced and aquaculture produces and the generation of the factory such as ight soil, paper mill, the organism of municipal wastes, food and drink processing is all wherein comparatively common waste.The above-mentioned waste of mode process of employing landfill or burning in the past, such waste is not only measured greatly, and water ratio is high, general water ratio about about 75%, volume, quality are all very large, result in process and transport very difficult, high cost, also can cause the insoluble secondary pollution problem to environment, also result in the waste of the resource of recyclable recycling.The recycling treatment of organic waste and utilization have more and more become the significant problem that China is badly in need of solving.Composting technology makes organic waste reach stabilization and innoxious one economy and effective means.And in the fermenting process of composting, be just faced with the problem of volatilization gas mixture contaminate environment urgently to be resolved hurrily.
Along with socioeconomic development, ventilation (oxygen) technology that current domestic fermentation adopts, mainly positive airway pressure technology, namely wind groove is used, airduct perforate is embedded in fermenting mixture or bottom surface, hole is generally vertically upward or side is offered, and lay cover plate above, with gas blower toward wind groove, airduct air-blowing (oxygen), the moisture of evaporation is through heap surface, outwards fly away, these contain carbonic acid gas, hydrogen sulfide, the waste gas of micro-ammonia and some other small molecular organic acid etc. is taken out of in the lump and is evaporate in air, produce topsoil, and the moisture not easily collecting of volatilization, adverse influence is produced to environment.And when adopting this structure, material is easy to block perforate, and perforate only back cushion layer obstruct, perforate more easily blocks, and needs airduct to take out during cleaning, and operation is inconvenience extremely.
Summary of the invention
The present invention is intended to solve the problems of the technologies described above at least to a certain extent.
Primary and foremost purpose of the present invention is to provide the simple Air suction net of a kind of structure, wind guide tank arranges the barriers covering opening, and make at least one sidewall of barriers and the sidewall of wind guide tank leave gap, make steam pass through from gap and to be collected in air channel, thus reach the object of steam collection.
A further object of the present invention is to provide a kind of negative pressure fermentation steam gathering system adopting above-mentioned Air suction net, can realize the steam collection and treatment in lasting oxygen supply fermenting process.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of Air suction net is provided, comprise the wind guide tank of several bottom openings, to be located at bottom wind guide tank and with the air channel of described open communication, described wind guide tank is provided with the barriers covering described opening, and at least one sidewall of described barriers and the sidewall of wind guide tank leave gap.Wind guide tank arranges the barriers covering opening, and make at least one sidewall of barriers and the sidewall of wind guide tank leave gap, when the fermentation materials in Air suction net ferments, the steam produced can pass through from gap and be collected in air channel, take away the gas that fermentation produces, also take away most moisture, thus reach the object of steam collection.
