Organic solid waste composting aeration system

Abstract

The invention relates to an organic solid waste composting aeration system. The system is used for a dynamic bin type composting process, accurately controls the temperature and aeration rate of a compost body through a unique aeration mode matched with mechanical turning equipment, and can realize automatic collection of odor, high efficiency and low consumption. The organic solid waste composting aeration system comprises a temperature sensor, a perforated aeration pipe, an air blower, an induced draft fan, a valve, an odor collecting pipe and a connecting pipeline. In the fermentation bin,a pile-turning machine works according to a preset frequency, materials move from the head of the fermentation bin to the tail of the fermentation bin under the pile-turning action of the pile-turningmachine, and the materials are fed once after each pile-turning; the pile turning frequency in one fermentation period is n, and the materials in the fermentation bin can be divided into n sections according to the feeding sequence; and through the perforated aeration pipe correspondingly arranged at the bottom of the fermentation bin, air is blown or induced to the section of materials accordingto monitoring data of the temperature sensor at the corresponding position, and the technological purposes of ventilation aeration, odor collection and temperature control are achieved.

Description

technical field [0001] The invention relates to an aeration system for organic solid waste composting, in particular to a dynamic bin-type composting process, through which the temperature and aeration of the compost can be precisely controlled through a unique aeration mode matched with mechanical turning equipment. Air volume, and can realize the independent collection of odor, high-efficiency and low-consumption compost aeration system. Background technique [0002] Under the background of my country's rapid economic growth and continuous improvement of people's living standards, the output of solid waste has continued to increase, and the environmental problems caused by solid waste have become increasingly prominent. Among these solid wastes, organic solid wastes are highly concerned by the public because of their various characteristics, strong mobility, poor stability, wide range of influence, and large production volume. According to incomplete statistics: my countr...

Problems solved by technology

[0005] Although composting technology has been used for many years, there are still many problems; even the most efficient dynamic bin composting process has the following problems: first, the fermentation cycle is long and occupies a large area; second, the amount of aeration is large , the amount of deodorization is large, and the power consumption is large; third, there is no connection between aeration and turning, and mutual influence and restriction
