Temperature-control type double-layer cylindrical aerobic composting reactor

Abstract

The invention discloses a temperature-control type double-layer cylindrical aerobic composting reactor which comprises a small cylinder (2) and a large cylinder (1), wherein the small cylinder (2) is coaxially arranged inside the inner cavity of the large cylinder (1); an outer vent pipe insertion opening (14) and the like are arranged on a large top lid (11) of the large cylinder (1); an inner vent pipe insertion opening (24) and the like are arranged on a small top lid (21) of the small cylinder (2); a partitioning layer (3) for holding materials is arranged inside the inner cavity of the small cylinder (2); a partitioning layer vent pipe insertion opening (31) and the like are arranged on the partitioning layer (3); the lower end of a vent pipe (4) penetrates through the insertion opening and is positioned inside the inner cavity of the small cylinder (2) below the partitioning layer (3); the lower end of the vent pipe (3) is connected with a gas distribution pipeline (8); and the upper end (41) of the vent pipeline (4) is connected with a draught fan. The temperature-control type double-layer cylindrical aerobic composting reactor can be applied to high-temperature matured compost of dredging bottom mud, biomass and the like to further realize ecologic treatment on solids and wastes.

Description

technical field [0001] The invention belongs to the technical field of utilization of solid waste biomass resources, in particular to a temperature-controlled double-layer cylindrical aerobic composting reactor, in particular to a double-layer composting reactor capable of uniform gas distribution and heat preservation. Background technique [0002] With the increase of population, the development of industry and agriculture, and the acceleration of urbanization, the load of rivers and lakes has increased year by year, resulting in the accumulation of pollutants in water bodies and sediments, and the degree of eutrophication of lakes has become increasingly serious. The sediment is not only the reservoir of pollutants in rivers and lakes, but also the source of internal pollution. Even if the external source pollution is controlled, the pollutants accumulated in the sediment will be released to the upper water body, thereby affecting the water quality. A powerful measure of ...
