An anaerobic decomposition furnace for domestic waste

Abstract

The invention discloses an anaerobic decomposition furnace for household garbage, which comprises an inner cylinder, an outer cylinder, a driving mechanism, a first feeding machine, a second feeding machine and a discharging machine, both the outer cylinder and the inner cylinder are horizontal, and the driving mechanism Drive the outer cylinder to rotate, the inner cylinder and the outer cylinder are coaxially fixed in the outer cylinder, there is a heating chamber between the rear end of the outer cylinder and the inner cylinder, the inner cylinder has a first inclined lifting material plate, and the outer cylinder has a second inclined lifting material plate, the discharge end of the first feeder passes through the front end of the outer cylinder and the front end of the inner cylinder in sequence and communicates with the inner cavity of the inner cylinder, and the feed end of the discharge machine passes through the rear end of the outer cylinder and the The rear end communicates with the inner cavity of the inner cylinder. The discharge machine has a gas outlet and a solid outlet. The solid outlet communicates with the feed end of the second feeder. The discharge end of the second feeder communicates with the heating chamber. The outer cylinder The front end has a waste residue outlet. The domestic garbage anaerobic decomposition furnace provided by the invention can recycle and utilize the energy remaining in the domestic garbage, has low energy consumption for garbage decomposition, and can continuously decompose garbage.

Description

technical field

[0001] The invention relates to the field of garbage treatment, in particular to an anaerobic decomposition furnace for domestic garbage. Background technique

[0002] At present, the status quo of domestic and foreign domestic waste decomposition equipment; there are many forms of domestic and foreign municipal waste treatment and decomposition equipment, but they can basically be summarized as follows; one is the compression decomposition method: the domestic waste is compressed and formed, and then the compressed briquetting is placed In the calciner, after more than 48 hours of decomposition, it is converted into carbon, and the waste gas generated needs to be treated. The second is the direct decomposition method: after the garbage is sorted, the decomposable organic components are dried and put into the decomposition furnace, and then ignited and burned to decompose slowly from the bottom upwards. This method takes a long time to decompose, consumes a l...
