Abstract
The utility model relates to an air draft net structure and a negative pressure fermentation water vapor collection system with the same. The air draft net structure comprises a plurality of air guide grooves with the opened bottoms, and air ducts arranged at the bottoms of the air guide grooves and communicated with openings in the bottoms of the air guide grooves, wherein separation members covering the openings are arranged on the air guide grooves; and a gap is formed between at least one side wall of each separation member and the side wall of the corresponding air guide groove. According to the air draft net structure, the separation members covering the openings are arranged on the air guide grooves, so that water vapor can pass through the gaps and be collected into the air ducts. The negative pressure fermentation water vapor collection system adopting the air draft net structure is characterized in that the air draft net structure is arranged at the bottom of fermentation material in a fermentation bed body, and is connected with a negative pressure generator. When the material generates water vapor during fermentation, the negative pressure generator generates negative pressure suction, and sucks and discharges the water vapor collected in the air draft net structure to achieve the moisture collection, and under the action of the negative pressure suction, air above the fermentation material is sucked together with the moisture, and air in the fermentation material is further supplied, so that the fermentation material can be subjected to continuous fermentation.
Description
Technical field
The utility model relates to the fermentation equipment technical field, more specifically, relates to a kind of air draught web frame and adopts the negative pressure fermentation steam gathering system of this structure.
Background technology
In the aerobic fermentation process, behind fermenting mixture material bubbling air (oxygen), under suitable C/N ratio, moisture and microbial process, the fermenting mixture material produces fermentation, material temperature can reach more than 50 ℃, the heat that fermentation produces is discharged the moisture evaporation in the fermenting mixture outside the fermenting mixture windrow.
Methane, carbonic acid gas, hydrogen sulfide, micro-ammonia and the some other small molecular organic acid etc. that produce are taken out of in the lump and are evaporate in the air but moisture evaporation will be fermented, and produce topsoil, and the moisture of volatilization easily collecting not, and environment is produced adverse influence.
Especially the atmosphere polluting problem that produces in the organic waste disposal process is serious day by day.At present, growing industrial and agricultural production brings bigger waste treatment problem, and for example already to produce a large amount of mud that a large amount of stalks of producing with aquaculture and factories such as ight soil, paper mill produce, the organism of municipal wastes, the tailing in the food and drink processing etc. all be wherein comparatively common waste to agricultural planting.Adopted the mode of landfill or burning to handle above-mentioned waste in the past, such waste is not only measured greatly, and water ratio height, general water ratio about about 75%, volume, quality are all very big, have caused processing and transportation very difficult, and cost is too high, also can cause insolublely to the second environmental pollution problem, also cause 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 solution is badly in need of in China.The composting technology is to make organic waste reach stabilization and innoxious a kind of economy and effective means.And in the fermenting process of composting, just be faced with the volatilization gas mixture problem of environment pollution caused that needs to be resolved hurrily.
Along with The development in society and economy, ventilation (oxygen) technology that present domestic fermentation is adopted, it mainly is the positive airway pressure technology, namely use the wind groove, the airduct perforate is embedded in the fermenting mixture or the bottom surface, the hole is generally vertically upward or the side is offered, and lay cover plate in the above, with the past wind groove of gas blower, airduct air-blowing (oxygen), moisture evaporated is through the 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 the air, produces topsoil, and the moisture of volatilization is easily collecting not, and environment is produced adverse influence.And when adopting this structure, material is easy to stop up perforate, and perforate only depends on bed course to intercept, the easier obstruction of perforate, and need take out airduct during cleaning, operation is inconvenience extremely.
