Embodiment Construction

[0021] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] to combine figure 1 As shown, the stage blast composting device of the present invention includes a reaction tank 1 , a blast unit 2 and a stirring unit 3 .

[0023] The top of the reaction tank 1 is provided with a feed port 11, and the bottom is provided with a discharge port 12, and four partitions 13 are arranged in the interior of the reaction tank 1 along the height direction, thereby dividing the interior of the reaction tank 1 into five regions. , from top to bottom are compost material bacterial liquid mixing area, primary fermentation reaction area I, primary fermentation reaction area II, secondary fermentation reaction area and decomposing storage area. At the same time, each partition 13 is provided with a discharge hole for the material to enter the next adjacent area through the partit...

Abstract

The invention belongs to the technical field of composting devices, and particularly relates to a stage air-blowing composting device. The stage air-blowing composting device aims at solving the problems of long composting period and high energy consumption when existing composting devices are adopted for conducting aerobic composting treatment on organic solid waste. The stage air-blowing composting device comprises a reaction tank, an air blowing unit and a stirring unit; the reaction tank is internally provided with four clapboards which divide the interior of the reaction tank into five regions, and each clapboard is provided with a discharge hole; the air blowing unit is provided with a main pipe, a plurality of branch pipes and a plurality of air distribution pipes, and the air distribution pipes are arranged in different regions in the tank body respectively and communicated with the main pipe through the independent branch pipes; the stirring unit includes blades connected to arotating shaft, and at least one set of blades are arranged on each clapboard. By means of the stage air-blowing composting device, oxygen can be accurately supplied according to the demand amount ofoxygen in different stages of aerobic composting fermentation, the oxygen utilization rate is increased, the composting period is shortened, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of composting devices, and in particular relates to a stage blowing composting device. Background technique [0002] With the continuous increase of my country's urban population, rapid economic development, and the acceleration of urbanization, more and more solid waste needs to be treated in a timely and effective manner. Among them, aerobic composting technology is the most widely used organic solid waste biological processing technology. Aerobic composting means that under aerobic conditions, aerobic bacteria absorb, oxidize, and decompose waste. Through their own life activities, microorganisms oxidize part of the absorbed organic matter into simple inorganic matter, and at the same time release activity that can be used for microbial growth. The required energy, while another part of the organic matter is synthesized into new cytoplasm, so that the microorganisms continue to grow and reproduce, thereby...
