Embodiment Construction

[0063] see figure 1 As shown, the foundation platform 1 is built by impermeable and airtight compressive materials, such as concrete material. In the support foundation 1, the air distribution pipe 4 is laid on the bottom of the compost heap 16, and the ventilation holes 3 are evenly distributed on the air pipe. Pipe 4 is made of anti-corrosion material (such as PVC, steel pipe). Each compost heap corresponds to one or several air distribution pipes. One end of the air distribution pipe is connected with the main air distribution pipe and independently controllable blowing equipment, and the other end It is closed with a pipe plug, and the air distribution pipe is laid in the compact and compressive foundation platform 1. A cleaning tank is left at one end of the pipe plug, and a leachate buffer discharge device is installed in the cleaning tank. Can open pipe plug 17 and open ventilation when foreign matter or leachate infiltrate in the pipe, foreign matter and leachate are c...

Abstract

The invention discloses a system and a method for ventilating stacks and collecting exhaust gases and percolate of compost. At least one air tube is laid in a base at the bottom of each stack along a length direction of the stack; grooves are reserved on the bases above vents of the air tubes; ventilation protecting layers are laid in the grooves above the vents; one end of each air tube is connected with a main air tube connected with a blower, while the other end is sealed with a pipe closer; a percolate outlet is downwards reserved at the closed end of each air tube; cleaning grooves are reserved on the peripheries of the pipe closers and the percolate outlets; percolate buffering and discharging devices connected with the percolate outlets are arranged in the cleaning grooves; an exhaust pipeline is arranged above each stack along the length direction; exhaust openings are distributed at the bottom of the exhaust pipeline; and each exhaust pipeline is connected with a main exhausttube. The system and the method have the advantages of greatly reducing the quantity of civil engineering at the same time of ensuring relatively better oxygenation state in the whole composting body, and simultaneously realizing the directed and highly-efficient collection of the exhaust gases produced in a composting process; and the system has a simpler structure and is convenient to operate.

Description

technical field [0001] The invention relates to an organic waste composting treatment system and a composting method. Background technique [0002] High-temperature aerobic fermentation, commonly known as composting, is a common method of organic waste treatment. Composting has forced ventilation and natural ventilation. The ventilation technology usually used in forced ventilation technology is in compost stacks, containers (reactors) or fermenters. The entire bottom area of ​​the porous bed is uniformly arranged with holes, and the bottom of the plate is a gas buffer cavity (chamber), which is equipped with air supply pipelines, valves and blowers. The bottom of the porous bed is evenly and densely arranged with pores ; The exhaust gas produced in the composting is discharged in disorder or sucked away through the air duct set up in the composting room, and the leachate is collected through another reserved ditch and ditch. This common technology of blindly pursuing a lar...
