By above-mentioned innovative technology scheme, the invention has the beneficial effects as follows:
Adopt the technical program, after the fermentation tower body is installed exhaust gas cleaner and blower fan, the band dust that can come out in the tower body in the operation process that ferments fermentation tower and the fermentation tail gas of stink carry out centralized collection, in exhaust gas cleaner, successively finish dedusting and deodorizing and handle the back qualified discharge, effectively prevent the generation of secondary environmental pollution; Simultaneously, exhaust gas cleaner and blower fan are in the course of the work, realized fresh air from the forced ventilation that tower body bottom inlet mouth enters, fermentation tail gas is extracted out from top of tower, the tower body inner air flow is smooth and easy, and the organism of fermentation oxidation is supplied with sufficient, active high, fermentation state is good, and the water vapor that is evaporated in the material is in time discharged, and reduces atmospheric moisture in the tower body significantly, the cycle of organic materials fermentation maturity and mummification obviously shortens, and fermentation efficiency improves more than 30%.
Description of drawings
Fig. 1 is the structural representation of preferred embodiment of the present invention.
The accompanying drawing marking explanation is as follows: tower body 1, fermentation bed 2, exhaust gas cleaner 3, fly-ash separator 4, deodorizer 5, blower fan 6, feeding conveyor 7, outfeed belt conveyor 8, inlet mouth 9, opening for feed open and close valve 10, discharge port opens and closes valve 11.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the tower body 1 of fermentation tower of the present invention is circular tower body, also can be square tower body, and 2 layerings of fermentation bed are installed in the tower body 1 successively, and fermentation bed 2 has 8 layers, and during fermentation tower work, organic materials ferments at fermentation bed 2.Exhaust gas cleaner 3 is installed in the top of tower body 1, collects the fermentation tail gas in the tower body 1 from the top; Exhaust gas cleaner 3 is combined by fly-ash separator 4 and deodorizer 5, also can be to adopt deodorizer separately; Fly-ash separator 4 is fixedly mounted on the top of tower body 1, and its working space is connected with tower body 1 internal space by the opening at tower body 1 top, and deodorizer 5 is installed in the exit end of fly-ash separator 4, and blower fan 6 is installed in the exit end of deodorizer 5.Fly-ash separator 4 can be selected cloth bag pulsaire collector or cyclone dust collector for use, the powder method in the fermentation tail gas can be filtered with the cloth bag pulse method, and by its deashing mechanism the dust discharge that filters be got back in the fermentation materials on the fermentation bed 2 of top layer; Deodorizer 5 can be selected photodissociation oxidation style deodorizing equipment for use, adopts the photodissociation oxidation technology to be oxidized to harmless carbon dioxide and water molecules through the foul smell molecular breakdown in the fermentation tail gas of fly-ash separator 4 dust removals by filtration; Blower fan 6 is centrifugal blower or aerofoil fan, by its suction function, realizes the forced ventilating of fermentation tower tower body 1 inside.In order to make the fermented organic material on each layer fermentation bed 2 in the fermentation tower tower body 1 can both obtain ozone equably, also reach forced ventilation in the tower body 1, on tower body 1 lower circumference, one deck fermentation of end bed 2 below evenly offer several inlet mouths that communicates with space outerpace 9, guarantee that fresh air enters from the fermentation tower bottom, fermentation tail gas is collected from the top of tower body 1 and discharges after finishing purifying treatment.
In order to realize the automatic feed/discharge of fermentation tower, in the tower body outside feeding conveyor 7 and outfeed belt conveyor 8 are installed, the opening for feed on the exit end of feeding conveyor 7 and tower body top joins, and the discharge port of the entrance end of outfeed belt conveyor 8 and tower body bottom joins.Feeding conveyor 7 rises to the top of fermentation tower with fresh organic materials from low level, is routed on the fermentation bed 2 that is positioned at top layer through opening for feed, and feeding conveyor 7 is high spud angle rib rotary conveyors, also can be worm conveyor; In the fermentation tower bottom outfeed belt conveyor 8 is installed, the organic materials of finishing fermentation is come out from tower body 1 delivered inside; Described outfeed belt conveyor 8 is rib rotary conveyors, also can be worm conveyor.
Come out through opening for feed and discharge port for fear of undressed fermentation tail gas, improve the collection effciency of fermentation tail gas simultaneously, the discharge port in the opening for feed at tower body 1 top and bottom is separately installed with and prevents that the opening for feed that leaks gas from opening and closing valve 10 and discharge port opens and closes valve 11; Described opening for feed opens and closes valve 10 and discharge port keying valve 11 is automatic open and close, also can be artificial opening and closing before and after the input and output material.
Groundwork principle and the working process of the embodiment of the invention are as follows: fermentation tower is in the startup running status, unlatching is positioned at exhaust gas cleaner 3 and the blower fan 6 at fermentation tower tower body 1 top, ozone is sucked in the tower body 1 by the inlet mouth 9 from tower body 1 bottom, the band dust that comes out in the organic materials fermenting process and the fermentation tail gas of stink upwards flow, enter in the fly-ash separator 4 of exhaust gas cleaner 3, wherein dust is stopped that by the cloth bag of fly-ash separator 4 filtration puts back in the organic materials in the fermentation bed 2 that is in the tower body 1 top layer side by side earlier, non-dusting fermentation tail gas enters in the deodorizer 5, emitted by the airduct of photodissociation oxidation removal stink by blower fan 6 therein, realize the environmental protection production of fermenting process.
