The lower lasting maintenance of degree is more than 4 days, and after 4-10 days one time fermentations, windrow enters second of fermentation 8-10 days.At second
It carries out using the turner turning over throwing before fermentation process.
During the fermentation, since the generated odorous substance that ferments is detected and uploaded to by air quality detector
Controller, when air pollution index reaches certain value, controller controls the induced draught system by odorous substance by drawing
Air hose is transported to absorption tower.Odorous substance by absorption tower filter layer, controller control spray equipment spray water or its
On his solution to filter layer, the particulate matter in odorous substance is dissolved in water, with the collecting tank of liquid flow to bottom, is cleaned
Gas by filter layer be discharged.
Wherein, temperature sensor, humidity sensor monitor and upload temperature and humidity condition to controller, controller at any time
As the case may be, the temperature of automatic control heating device heating.
Before second of fermentation process, the deodorization device is opened while opening cover film, prevents odorous substance
It is excessive.
For the turner in machine slot, described turn over can effectively prevent heap body between polishing system and fermentation system across partition board
Corrosion to turner.Before turning over throwing, controller sends increase instruction to lifting gear, and turner is made integrally to be higher than partition board, control
The servo motor of device control turner slides into mixing channel by machine slot, when the turner slides into above mixing channel, drop
The low lifting gear and then the height for reducing turner, make the turner turn over cast material.
The cover film is closed after turning over throwing, the deodorization system can be closed after workshop is interior not without odorous substance
System.
After fermenting, open the full-automatic turning device, by the product after secondary fermentation be poured over transport vehicle or other
In apparatus for placing, the padded height of mixing channel of the basal layer of the bottom of the fermentation tank enables the mixing channel to meet transport
The requirement for height of vehicle or other apparatus for placing realizes heap body rapid dumps, saves the amount of labour and time.
Wherein, controller is connected with scraper plate energization, and during toppling over, controller controls the scraper plate by two
Product after secondary fermentation is blown into transport vehicle or other apparatus for placing.
Product sieving after secondary fermentation is simultaneously decomposed at recycling product, and screenings is as back-mixing material return batch mixing
Storehouse, as organic adjuvants.
The utility model has the advantage of：The utility model overcomes many of traditional open sludge aerobic fermentation system
Drawback provides a kind of enclosed sludge aerobic fermentation system, realizes that fermentation process whole process is detectable and intelligentized control method, together
When reduce energy consumption, realize " minimizing, stabilisation, innoxious, recycling " processing of municipal sludge, there is apparent environmental protection
Benefit and economic benefit.During the fermentation, deodoration system needs continual operation in 24 hours to common trough type fermentation system,
Power consumption is more, and the fermentation of slot type overlay film is enclosed fermentation, and fermentation tank has insulation effect, therefore can shorten fermentation time, and
Stink will not be excessive, has induced draught system and air quality detector in fermentation tank, in the course of work of fermenting, pollution index reaches
Induced draught system can be automatically opened to controller when certain reach the standard grade and carries out deodorization, reduce the operating cost of deodoration system.The present apparatus
Deodoration system need to be only opened when turning over throwing, the deodoration system working time is 2-4 hours/day, therefore greatly reduces deodoration system
Operating cost.The present apparatus by turner be located on mixing channel in a manner of sliding rail, controller automatically controls turner, therefore
Automatic Control is realized, it is automatic to manage, it need not go to carry turner again.After fermentation, full-automatic turning device is by two
Product after secondary fermentation is poured in transport vehicle or other apparatus for placing, realizes heap body rapid dumps, and it is timely to save labour cost
Between.
