Totally enclosed water-gas linkage intermittent internal rotation anaerobic digestion device with constant temperature for house refuse

Abstract

The invention provides a totally enclosed water-gas linkage intermittent internal rotation anaerobic digestion device with constant temperature for house refuse, which comprises a fermenter body, a tank top, a first, a second, and a third circulating pumps arranged outside the fermenter body, a feed pump and an inoculation pump, a biogas reflux pump, a slurry mixing tank, a mud and sand separator and a seed tank. The inner wall of the fermenter is provided with four sets of inner ring tubes from top to bottom. The fermenter is provided with an inner jet assembly in the center thereof, and a biogas backflow spray ring is arranged under the jet assembly base. Output ends of the second and the three circulating pumps are respectively connected with the first, second and third inner ring tubes. The upper part of the side wall of the fermenter is provided with an overflow port and an upper balance port; the overflow port and upper balance port are simultaneously connected with a lead-out pipe, which is connected to input ends of the first, second and third circulating pumps. The feed pump and the inoculation pump are connected with the output of the first circulating pump. The biogas reflux pump is connected to the biogas backflow spray ring. The outer wall of the fermenter body is also provided with an outside heating adjoining tube.

Description

technical field [0001] The invention relates to a digestion device, in particular to a fully enclosed water-gas linkage intermittent internal rotation constant temperature anaerobic digestion device for domestic waste Background technique [0002] Existing anaerobic digestion devices for domestic waste and organic matter cannot achieve complete resourceful and harmless treatment of domestic waste and organic matter (such as sludge from sewage treatment plants, feces from septic tanks in residential quarters, etc.). Most of them are naturally heated, naturally fermented, and statically fermented. Dust is generated when materials enter the warehouse, which affects the working environment of the workshop. The material is not fermented completely, and the fermentation cycle is long. The biogas output is low, and the liquid surface produces a "mash cover" during the fermentation process. Sediment separation If it is not thorough, the bottom will be hardened due to sediment deposi...

Problems solved by technology

[0002] The existing anaerobic digestion devices for domestic waste and organic matter cannot be completely resourced and harmless for domestic waste and organic matter (such as sludge from sewage treatment plants, feces from septic tanks in residential areas, etc.)

Most of them are naturally heated, naturally fermented, and statically fermented. Dust is generated when materials enter the warehouse, which affects the working environment of the workshop. The material is not fermented completely, and the fermentation cycle is long. The biogas output is low, and the liquid surface produces a "mash cover" during the fermentation process. Sediment separation Incomplete, the bottom is compacted due to sediment deposition, and the biogas residue cannot effectively kill harmful bacteria, its adaptability is not strong enough, and it is not convenient for industrialization
