Windrow composting aeration system

Abstract

The invention discloses a windrow composting aeration system which comprises a groove and a gas pipe, wherein the groove is formed in a pre-composting ground along a windrow orientation and has a width smaller than that of wheels of a turning and throwing machine; the gas pipe is laid at the bottom of the groove; a plurality of aeration notches are formed in a pipe wall of the gas pipe; other parts in the groove are filled with rice husks. The windrow composting aeration system provided by the invention has the functions that gas is supplied by the gas pipe rather than the groove; the gas pipe does not interfere with turning and throwing, can supply gas without blockage, can discharge accumulated water automatically, and the like, so that the windrow composting aeration system is more sufficient in the amount of supplied oxygen, rapid to heat up, high in fermentation temperature, short in fermentation period, rapid in material turnover, and high in productivity.

Description

technical field [0001] The invention relates to the field of compost aeration. More specifically, the present invention relates to a strip-stack compost aeration system. Background technique [0002] Composting is a treatment method that converts easily biodegradable organic components in organic solid waste into humus, biogas, protein, ethanol or sugar through microbial degradation technology, so as to achieve harmless solid waste. Composting technology is divided into : Aerobic composting and anaerobic composting, aerobic composting is based on aerobic bacteria to absorb, oxidize and decompose waste. Through their own life activities, microorganisms oxidize a part of the absorbed organic matter into simple inorganic matter, release the energy required for biological growth activities, and convert another part of the organic matter into new cell substances, so that the microorganisms grow and reproduce, and produce more organism. The temperature of the aerobic composting...

Problems solved by technology

[0006] The disadvantages are: the stacking height is usually 1 to 1.2 meters, so the floor area is relatively large, and the site utilization rate is low; the compost fermentation and maturity are slow, the composting cycle is long, and the output is low

At present, many manufacturers try to maintain continuous oxygen supply through forced air supply or forced air extraction, so as not to form anaerobic odor, such as inserting tracheal tubes, adding granular fillers to increase air permeability, and slotting the ground to blast air, etc., but the results are not effective. ideal

Inserting the air pipe makes it difficult to turn the pile. Adding granular fillers needs to screen out the fillers and refill them, resulting in a decrease in production capacity. Grooving on the ground and blowing air is easy to accumulate water and block
