摘要

innovative industrial process and equipment for urban, agroindustrial, agricultural and / or sewage sludge drying by means of a physical-chemical-mechanical method for use in the production of organic fertilizers, fertilizers and / or compounds. The present invention relates to the creation of equipment and industrial process of drying of urban, agroindustrial, agricultural and / or sewage sludge by means of physical-chemical-mechanical method for use in the production of fertilizers, fertilizers and / or organic compounds. Such equipment and industrial process for reducing humidity consists of the use of an oven (No. 01), thermally insulated by a glass plate (No. 4) for preservation of ambient and indoor heat, with a length of 27 meters or more. or less, mounted in 2.5 meter modules, coupled according to the need of drying demand of the mentioned residues. The process begins by introducing the products to be dried at the furnace inlet (n.ol) at a suitable temperature to be driven by eight conveyor threads (n ° o2) under the action of ten gas-fired heaters. , firewood or others (n. 03). Of the eight conveyor threads, four produce the upper outward movement of the products and four perform the reverse path, that is, the lower back movement. two gearmotors (No 05) are located at both ends of the furnace: the first at the inlet of the product, ie the organic matter, with a high moisture content (87% for sewage sludge, for example). ), driven by four upper level conveyor threads, and the second at the lower level return point of the raw material by four other conveyor threads, both levels within the oven being subjected to a sufficiently adequate temperature capable of significantly decreasing the humidity of the waste on a large scale, in a short time, allowing its unprecedented manipulation in the physical-chemical-mechanical composting used in the production of organic or organic fertilizers. At the end of the application process, a substantial reduction in moisture content of the organic matter from 87% to 17% (in the case of sewage sludge) is to be discharged directly onto a haul truck.
