Temperature-controlled energy-saving composting greenhouse

Abstract

The invention discloses a temperature-controlled energy-saving composting greenhouse. The greenhouse comprises a first wall body and a second wall body, wherein a shed roof is arranged above a position between the first wall body and the second wall body, door bodies which are arranged below the shed roof are arranged at two ends of the first wall body and the second wall body, gas purification equipment which is positioned in a livestock holding platform is arranged at the outer side of the first wall body, one end of a gas collecting pipe of the gas purification equipment is connected with the gas purification equipment, and the other end of the gas collecting pipe penetrates into the composting greenhouse from the shed roof and extends to the other end of the greenhouse along the lowerpart of a ridge. According to the temperature-controlled energy-saving composting greenhouse adopting the structure, solar heating is taken as the main, and underfloor heating is taken as a subsidiary, the temperature-controlled oxygen-supply fermentation is carried out by combining spiral turning and window ventilation, the composting process is not affected by the low temperature in winter, thecomposting time is effectively shortened; and meanwhile, the gas in composting greenhouse is collected and purified, and the energy-saving environment-friendly cost is low.

Description

technical field [0001] The invention relates to the technical field of breeding waste treatment, in particular to a temperature-controlling energy-saving composting greenhouse. Background technique [0002] Over the years, my country's animal husbandry industry has continued to develop, and the level of large-scale and specialized breeding has been continuously improved. While ensuring the supply of meat, eggs and milk, a large amount of livestock manure and other wastes have been generated. These wastes cannot be treated in a timely and efficient manner, seriously polluting the surrounding environment of farms and households, and becoming a major problem in environmental governance. [0003] The existing solid manure fermentation and retting technologies are mainly aerobic fermentation and anaerobic fermentation. Because anaerobic fermentation is slower than aerobic fermentation and takes a long time, aerobic fermentation and retting are mostly used in farms. The methods o...

AI Technical Summary

Problems solved by technology

Among them, the fermentation equipment in the fermentation bin has a high degree of automation and fast fermentation, but the equipment is expensive, consumes a lot of energy, and the production cost is high.

Strip-stack and tank-type fermentation have a low degree of automation. Generally, mechanical turning is used for ventilation and oxygen supply. There is no heating facility, and the fermentation temperature is inconvenient to control. It only depends on the natural temperature of the external environment. Faster than autumn and winter, the slowest in winter

The temperature in winter in northern my country is mostly below 0 degrees or even tens of degrees below zero. The reproduction of fungi almost stops, and the fermentation is slow or stopped. Increased pollution
