The present invention has the environmental protection fermentation tower of tail gas purifying function, and described opening for feed and discharge port are separately installed with the keying valve preventing from leaking gas.
By above-mentioned innovative solution, the invention has the beneficial effects as follows:
Adopt the technical program, after fermentation tower body installs exhaust gas cleaner and blower fan, centralized collection can be carried out to the fermentation tail gas that fermentation tower is carrying out band dust and the stink come out in tower body in fermentation operation process, in exhaust gas cleaner, successively complete qualified discharge after dedusting and deodorizing process, effectively prevent the generation of secondary environmental pollution; Simultaneously, exhaust gas cleaner and blower fan are in the course of the work, achieve that fresh air enters from tower body bottom inlet mouth, fermentation tail gas by the forced ventilation of extracting out from top of tower, tower body inner air flow is smooth and easy, and organism of fermentation oxidation supply is sufficient, active high, fermentation state is good, and the water vapor be evaporated in material is discharged in time, significantly reduces atmospheric moisture in tower body, the cycle of organic materials fermentation maturity and mummification obviously shortens, and fermentation efficiency improves more than 30%.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Accompanying drawing mark is described 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
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the tower body 1 of fermentation tower of the present invention is circular tower body, and also can be square tower body, fermentation bed 2 layering be installed in tower body 1 successively, and fermentation bed 2 has 8 layers, and during fermentation tower work, organic materials ferments in fermentation bed 2.Exhaust gas cleaner 3 is arranged on the top of tower body 1, the fermentation tail gas in collected overhead tower body 1; Exhaust gas cleaner 3 is combined by fly-ash separator 4 and deodorizer 5, also can be 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 arranged on the exit end of fly-ash separator 4, and blower fan 6 is arranged on the exit end of deodorizer 5.Fly-ash separator 4 can select cloth bag pulsaire collector or cyclone dust collector, the powder method in fermentation tail gas can be filtered by cloth bag pulse method, and to be got back to by the dust discharge of filtration in the fermentation materials in the fermentation bed 2 of most top layer by its deashing mechanism; Deodorizer 5 can select photodissociation oxidation style deodorizing device, adopts photodissociation oxidation technology that the foul smell molecular breakdown in the fermentation tail gas of fly-ash separator 4 dust removal by filtration is oxidized to harmless carbon dioxide and water molecules; Blower fan 6 is centrifugal blower or aerofoil fan, by its suction function, realizes the forced ventilating of fermentation tower tower body 1 inside.Ozone can be obtained equably to make the fermented organic material in the every one deck fermentation bed 2 in fermentation tower tower body 1, also forced ventilation in tower body 1 is reached, in tower body 1 lower circumference, the below of one deck fermentation bed of the most end 2 evenly offers several inlet mouths 9 communicated with space outerpace, ensure that fresh air enters bottom fermentation tower, fermentation tail gas is discharged after being collected purifying treatment from the top of tower body 1.
