Waste gas purification device for trough type compost fermentation

Abstract

The invention discloses a trough type compost fermentation waste gas purification device, which comprises a compost trough, cover layers, a ceiling and a gas collection channel, the cover layers are buckled on the top surfaces of the two sides of the compost trough, the gas collection channel is arranged on the cover layers, the ceiling is buckled above the compost trough, a detachable sealing structure is arranged on the outer sides of the buckling cover layer and the compost trough, and a plurality of opening gas collecting structures are arranged between the compost trough and the gas collection channel; and the trough type compost fermentation waste gas purification device has the beneficial effects that the trough type compost fermentation waste gas purification device is simple in structure and convenient to use, fermentation air is sealed and guided through a detachable sealing structure on the trough type compost fermentation waste gas purification device, materials are collected and fed through an axial flow fan, then the materials are introduced into a waste gas purification treatment structure for purification treatment to remove the peculiar smell and harmful gas in the waste gas, the trough type compost fermentation waste gas purification device is simple in structure and very convenient to use and replace, the treatment efficiency of fermentation waste gas is effectively improved, and the treatment difficulty is reduced.

Description

Technical field [0001] The present invention relates to the field of compost fermentation, in particular, for a trough compost fermentation exhaust gas purification device. Background technique [0002] The groove compost is a composting method for placing the stacked mixture in a long litter structure. The oxygen supply of the groove compost relies on the mixer, and the mixer is moved along the longitudinal axis of the groove, stirring the stacked during the transfer process. The depth depth in the compost groove is 1.2 to 1.5 meters, and the compost fermentation time is 3 to 5 weeks. [0003] During the use of the groove, the fermentation exhaust gas is usually accompanied by the production of fermentation exhaust gas, and the fermentation exhaust gas typically contains dedicated exhaust gas treatment, and the purification treatment of the fermentation exhaust gas in this stage is generally sealed. The shack is collected in direct exported manner, and when the shang is a long, ...

AI Technical Summary

Problems solved by technology

[0003] During the use of trough composting, it is usually accompanied by the generation of fermentation waste gas, which usually contains malodorous gases and greenhouse gases, and requires special waste gas treatment. At present, the purification treatment of fermentation waste gas usually adopts airtight The sheds are collected and processed directly, and when the sheds are longer in this way, the indoor air circulation rate will slow down, so the existing tank-type composting fermentation cannot effectively replace the gas in the large space, reducing the In view of this, in-depth research on the above problems resulted in this case
