specific Embodiment approach 1

[0024] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, this embodiment comprises composting room 1, compost bin 2, manure heap 4, leachate pool 5 and several distribution air pipes 3, and described several distribution air pipes 3 are arranged at the bottom of composting room 1, every A distribution air pipe 3 makes a reciprocating lifting movement along the height direction of the composting room 1. The leachate pool 5 is located at the bottom of the composting room 1 and is directly below several distribution air pipes 3. The side wall of the leachate pool 5 is processed There is an air inlet 6, and an air outlet 7 is processed on the side wall of the composting room 1. The interior of the composting room 1 is a composting bin 2, and a fertilizer pile 4 is arranged in the composting bin 2;

[0025] The top of each distribution air pipe 3 is a sealed end, and several air holes 8 are processed on the side wall of each distribution ai...

specific Embodiment approach 2

[0026] Specific implementation mode two: combination figure 2 Describe this embodiment, in this embodiment, the vent hole 8 is a tapered hole, the small mouth end of the vent hole 8 is arranged on the outer wall of the distribution air pipe 3, and the large mouth end of the ventilation hole 8 is arranged on the inner wall of the distribution air pipe 3. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0027] Embodiment 3: This embodiment is a further description of Embodiment 1 or 2. In this embodiment, each distribution air pipe 3 makes a reciprocating lifting motion along the height direction of the composting room 1 driven by the lifting mechanism.

[0028] In this embodiment, the lifting mechanism is an existing product. The lifting mechanism is that the meshing of the motor, the bevel gear set and the leading screw drive each distribution air pipe 3 to move up and down along the leading screw or the lifting mechanism is a pneumatic piston type telescopic rod to drive the distribution air pipe 3 to move up and down. Other existing lifting mechanisms that can realize manual or electric control are all all right.

[0029] Specific implementation mode four: combination image 3 Describe this embodiment, in this embodiment, the bottom of each distribution air pipe 3 is correspondingly provided with a bottom ring 9, and each bottom ring 9 is coaxially arranged with its corr...

Abstract

The invention relates to an arrangement device and method for composting, particularly a vertical gas distribution device of an aerobic composting bin and a gas distribution method thereof. At present, gas distribution pipes ventilated by force are liable to be blocked by organic materials so that local ventilation is nonuniform, cleaning is difficult and ventilation effects are poor. The device includes a composting room, a composting bin, a compost heap, a percolate tank and a plurality of branch gas distribution pipes. The plurality of branch gas distribution pipes are arranged at the bottom of the composting room. Each branch gas distribution pipe reciprocates along the height direction of the composting room. The percolate tank is at the bottom of the composting room and is right under the plurality of branch gas distribution pipes. The side wall of the percolate tank is provided with an air feeding port. The side wall of the composting room is provided with a gas outlet. The inside of the composting room is the composting bin. The compost heap is in the composting bin. The top of each branch gas distribution pipe is a sealed end. The side wall of each branch gas distribution pipe is provided with a plurality of vent holes. The bottom end of each branch gas distribution pipe is communicated with the percolate tank. The device and the method are used for ventilation during composting.

Description

technical field [0001] The invention specifically relates to a vertical air distribution device for an aerobic compost bin and an air distribution method thereof. Background technique [0002] In the composting process of organic solid waste, aeration is an indispensable work in the process. The aeration methods involved in the existing composting process are mainly turning aeration and forced aeration. At present, there are two main types of air distribution methods used in forced ventilation. Firstly, the perforated metal or other material pipes are inserted or pre-embedded into the pile, and the pipes are connected to the blower. During the operation of this kind of ventilation method, the ventilation holes will be blocked by organic materials, which will reduce the ventilation effect, and at the same time, due to the small surface area of ​​the pipeline, the gas distribution will be uneven. Second, the air distribution method of the prefabricated air distribution chann...
