Inner circular efficient compost system

Abstract

The invention discloses an inner circular efficient compost system which comprises a compost chamber, wherein a filtrate plate is arranged in the compost chamber; an exhaust gas guide pipe is arranged above the compost chamber; the exhaust gas guide pipe and an oxygen guiding pipe are respectively communicated with an air inlet of an air blower; an air outlet of the air blower is communicated with a head air pipe; the head air pipe penetrates through a side wall of the compost chamber from the outer side and extends to the position under the filtrate plate; a plurality of air guide branch pipes are arranged on the head air pipe; the air guide branch pipes vertically penetrate through the filtrate plate; a plurality of aeration ports are formed in the side walls of the air guide branch pipes so as to form an air flow circulating channel; a plurality of through holes are formed in the filtrate plate; a filtrate backflow pipe is arranged on the side wall of the compost chamber under the filtrate plate; the filtrate backflow pipe passes by a mechanical pump and then penetrates through the top of the compost chamber; a spraying device is arranged at the tail end of the filtrate backflow pipe, so that a filtrate backflow system is formed. The end product of the compost according to the invention is high in maturity degree and high in quality.

Description

technical field [0001] The invention belongs to the technical field of composting treatment, in particular to an internal circulation high-efficiency composting system. Background technique [0002] In the past, pig manure was treated on the basis of the principle of digestion by nearby farmers. During the peak agricultural season, nearby farmers came to drag a large number of pig manure for fish farming or fruit tree planting. In the off-season, there was no place to digest pig manure, and a large number of pigs The accumulation of manure seriously affects the epidemic prevention work; therefore, under this treatment method, pig manure has not been effectively solved fundamentally. First of all, fish farming and planting are seasonal, and pig manure is produced every day, and there is a large time lag between processing and production; secondly, farmers will cause secondary pollution to the environment during the process of dragging pig manure. This makes the requirements ...

Problems solved by technology

However, due to the large amount of composting raw materials in the existing composting system, excessive and frequent mechanical turning and throwing, the composting efficiency is low, which not only increases the production cost, but also is not conducive to the accumulation of composting heat to increase the composting temperature, and the composting is prone to hypoxia. , leading to anaerobic fermentation, which produces a large amount of organic acids and other malodorous gases and greenhouse gases such as NOx and methane, resulting in the release of a large amount of ammonia gas, loss of nutrients in the product, and serious pollution and harm to the surrounding environment
