OA19149A - Composteur aérobie de grande capacité (CAGC) - Google Patents

Abstract

Pendant cinq ans nous avons construit plusieurs composteurs sur la base du brevet 16549/BOPI 7/2014 qui concerne un dispositif innovant de compostage aérobie sans retournement en système semi-fermé. Une évaluation participative avec des organisations paysannes et des techniciens en la matière, a permis d'enregistrer certaines imperfections de conception qui réduisent de manière drastique l'opérationnalité du brevet 16549. La présente invention un composteur de grande capacité en système complètement fermé qui corrige les inconvenances techniques du fonctionnement du brevet 16549 (composteur à caissons), elle est durable et améliore très significativement les résultats attendus sur les plans technique et économique. Elle est dénommée «Composteur Aérobie de Grande Capacité (CAGC)» Les différentes conclusions auxquelles nous avons abouties montrent que le brevet 16549 est à ce jour obsolète.

Description

DESCRIPTION

STATE OF THE ART: The Large Capacity Aerobic Compost Bin (CAGC) is a closed composting system but it is indeed anaerobic, therefore the decomposition occurs in the presence of a sufficient quantity of oxygen.

All the different types of composting plants known until now and mentioned in the drafting of the composter patent 16549 / BOPI 7/2014 have been re-examined. These are: - artisanal composting in pits, - artisanal composting in windrows or piles with turning - industrial composting - composting in silos by forced aeration - industrial composting in windrows or static piles with active aeration or passive aeration and the composters electromechanical.

The operation of the CAGC is based on controlling temperature and humidity variations combined with controlled management of the quantities of organic matter.

Composting in the CAGC speeds up the composting process thanks to an adjusted and continuous balance of factors that condition fermentation. The conditions thus met, the composting time, the quantity and the quality of the compost are very significantly improved.

Like the composter of patent 16549 / BOPI 7/2014, the CAGC acts on the functional relationships between the volume of waste and the conditions of composting. Thus, by application of this principle, a large heap of fermentable waste is divided into several small batches placed in boxes which provide suitable conditions for the fermentation of the waste.

The CAGC is built in the form of a shed with shelves on which are placed batches of fermentable waste.

A liquid compost (leachate) recovery system is installed at the bottom of the hangar.

BRIEF DESCRIPTION

The Large Capacity Aerobic Compost Bin (CAGC) is a shed with shelves fixed at appropriate distances. Watering is from a water tank placed above the shed.

The ventilation system of the CAGC differs from that of patent 16549 by its double-flow ventilation blower manufactured with a temperature-sensitive material, the principle of which is based on "very low energy geothermal energy", that is to say ie capturing the energy contained in the soil whose temperature is less than or equal to 35 ° C. This system thus optimizes local ventilation by promoting cooling or heating of the environment thanks to the thermal inertia of the ground, which is between 1.50 meters and 2 meters deep. The renewal of the air in the CAGC is ensured by constantly maintaining the temperature and humidity in the blower buried 1.50m in the ground. The air circulates between the blower tunnel and the composter hangar thanks to the difference in temperature and humidity gradients of the blower and that of the CAGC composter. Thus the outside air can passively enter the CAGC to enrich the mass of the compost with oxygen.

Thanks to this tunnel, the greater the temperature difference between the interior and the exterior, the stronger the upward movement of the air which allows the stale air to be evacuated into the hangar. The ventilation device can be operated by electric or wind power to operate the ventilation system. The device is designed in such a way as to minimize the variations in temperature and humidity, thus allowing a constant fermentation of the organic matter.
