(3), when the windrow temperature surpasses 55 ℃, then again the tail gas of stoving oven is blowed to windrow uniformly by the windrow bottom;
(4), when the windrow temperature surpasses 65 ℃, air is blowed to windrow uniformly by the windrow bottom, the windrow temperature is reduced to below 55 ℃;
(5), when the windrow temperature no longer rises to more than 60 ℃, then one time fermentation is finished, and states the same Secondary Fermentation of step by entering after the turning to catch up with then.
Another object of the present invention provides the fermenter that the aerobic rapidly composting of a kind of municipal sludge is handled, and this fermenter can be realized the aerobic rapidly composting of municipal sludge convenient, efficiently in conjunction with aforesaid method.
For realizing aforesaid method, the present invention is by the following technical solutions: the fermenter that the aerobic rapidly composting of a kind of municipal sludge is handled, comprise the fermentation cell body, it is characterized in that: described cell body bottom is provided with breather line, described breather line radially is provided with production well, and end is provided with movable drain plug and is convenient to operate the magazine of plug.
A further object of the present invention provides a kind of using method of above-mentioned fermenter, and it can allow the use of the grasp fermenter that general operation person is familiar with, and makes ferment effect better, and efficient is higher.
This technology is achieved in that the using method of the fermenter that the aerobic rapidly composting of a kind of municipal sludge is handled, and it is characterized in that may further comprise the steps:
(1), with the object of required compost fermentation, after mixing by the compost formula rate, deliver to fermenter;
(2), open induced draft fan, with stoving oven tail gas introducing ferment groove, stoving oven tail gas is evenly blowed to the fermenter windrow by breather line;
(3), in the fermenting process, the windrow temperature that temperature controller analysis, treatment temp meter are gathered, the open and close of control induced draft fan.
The inventive method is simple, cooperates distinctive fermenter, can effectively improve the composting effect, improves compost environment, improves quality of compost products, realizes that to promoting solid organic castoff the arable land cycling and reutilization is significant.

Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
The invention provides the method for the aerobic rapidly composting of a kind of municipal sludge, it is characterized in that may further comprise the steps:
(1), with the object of required compost fermentation, after mixing by the compost formula rate, deliver to fermenter, and pile height to 1.2 ~ 1.5m;
(2), the tail gas of stoving oven is blowed to windrow uniformly by the windrow bottom, make windrow be warmed up to 6 ~ 10 ℃, stop to be blown into tail gas then;
(3), when the windrow temperature surpasses 55 ℃, then again the tail gas of stoving oven is blowed to windrow uniformly by the windrow bottom;
(4), when the windrow temperature surpasses 65 ℃, air is blowed to windrow uniformly by the windrow bottom, the windrow temperature is reduced to below 55 ℃;
(5), when the windrow temperature no longer rises to more than 60 ℃, then one time fermentation is finished, and states the same Secondary Fermentation of step by entering after the turning to catch up with then.
In order to allow above-mentioned method better realize, the invention provides the fermenter that the aerobic rapidly composting of a kind of municipal sludge is handled, comprise the fermentation cell body, it is characterized in that: described cell body bottom is provided with breather line, described breather line radially is provided with production well, and end is provided with movable drain plug and is convenient to operate the magazine of plug.Described breather line air intake place is provided with induced draft fan; Described induced draft fan is controlled by temperature controller; Described temperature controller is connected with and is used to insert the thermometer that windrow carries out temperature detection; Every 50cm a production well is set on the described breather line.
In order to allow those skilled in the art can better operate above-mentioned fermenter, the invention provides the using method of the fermenter of the aerobic rapidly composting processing of a kind of municipal sludge in addition, it is characterized in that may further comprise the steps:
(1), with the object of required compost fermentation, after mixing by the compost formula rate, deliver to fermenter;
(2), open induced draft fan, with stoving oven tail gas introducing ferment groove, stoving oven tail gas is evenly blowed to the fermenter windrow by breather line;
(3), in the fermenting process, the windrow temperature that temperature controller analysis, treatment temp meter are gathered, the open and close of control induced draft fan.
When breather line stops up, open magazine, plug, open induced draft fan then tamper is blown out.
Specifically, as Fig. 1, Fig. 2, shown in Figure 3, in preferred embodiment of the present invention, described fermentation cell body is by brick one-tenth body of wall 2, form fermenter 1, groove width 3m, high 1.2-1.5m, length is decided on topographic features, and long side bottom within the walls is apart from ground 5-6cm, Φ 5cm breather line 3 is installed, and on breather line every 50cm, make a call to the production well 4 of 1 Φ 1cm, a pipeline induced draft fan 5 is installed in the air inlet termination of breather line then, end at breather line is installed a movable drain plug 6, and there are magazine 7 inside in plug 6.The breather line inlet end is installed an induced draft fan 5, and to increase pipeline air pressure, induced draft fan outer end ventpipe links to each other with the pipeline 8 that absorbs air with the exhaust pipe 9 of dryer respectively.Fermented sludge is built the heap back and is inserted thermometer 10, and thermometer connects temperature controller 1 by electric wire, temperature controller control induced draft fan 5.
In use, we open magazine 7 earlier, with plug 6 the ventpipe end is blocked up, then with the object of required compost fermentation, after mixing by the compost formula rate, deliver to fermenter 1, piling 1.2-1.5m highly gets final product, after having built heap, at first pass through induced draft fan 5 with dryer tail gas, stoving oven tail gas is introduced the breather line 3 of windrow, and by ventilating pit 4, blow to the fermenter windrow equably, the interior windrow of groove is heated, approximately ventilated 1 hour, can improve temperature of charge 6-10 ℃ so fast, to promote the high temperature bacterium to breed fast, it is dark vertically to insert 40cm with thermometer, so that understand heap temperature, built heap back 24 hours, with breather line 3 ventilation 20-30 minutes of stoving oven tail gas introducing windrow, after 48 hours, heap temperature will rise to more than 55 ℃ again, then, then control induced draft fan 5 by temperature controller and force the breather line 3 of stoving oven tail gas introducing windrow is ventilated, when the windrow temperature of thermometer 10 surveys surpassed 65 ℃, then temperature controller 11 was opened induced draft fan 5 startups, force bubbling air for the windrow in the fermenter 1, give the aerobic microbiological supplemental oxygen so on the one hand, make aerobic microbiological keep vigorous growth conditions, fast degradation of organic substances; On the other hand, at bubbling air, can take away water vapour, distribute heat avoids windrow too high, causes organic carbon, and below material temperature drop to 55 ℃, then temperature controller 11 is closed induced draft fan 5 and quit work.This stage is commonly referred to as one time fermentation, needs 7-10 days, and the organism major part in heap body material is degraded, and heap body temperature of charge no longer rises to more than 60 ℃, and then one time fermentation is finished, and then, enters Secondary Fermentation by turning.In the turning process, if tiny windrow enters ventpipe from ventilating pit, then can cause breather line to stop up, at this moment, need only open magazine 7, and open plug 6, then, open induced draft fan 5, then the foul in the ventpipe can be blown out from its end port, keep breather line unobstructed by the induced draft fan forced ventilation.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
