Controlled biological fermentation device in greenhouse

Abstract

The invention discloses a controlled biological fermentation device in a greenhouse. The controlled biological fermentation device comprises a frame body, a material compartment, an air distribution ventilation device, a heating device and a spraying device; Super-heavy casters are mounted at four corners at the bottom of the frame body, a waste liquid collection tank is mounted at the top of theframe body, the material compartment is mounted at the top of the waste liquid collection above the frame body, the air distribution ventilation device is mounted at the bottom of the inner side of the material compartment, the spraying device is mounted at the top of the inner side of the material compartment, and the heating device is mounted and distributed on an inner side wall around the material compartment. The controlled biological fermentation device disclosed by the invention has the benefits that heat produced by fermentation is used for heating the greenhouse, and gas produced by fermentation is filtered and conveyed to the greenhouse, and a CO2 gas fertilizer is supplemented for plants; O2 produced by the plants in the greenhouse is collected and recycled to meet the oxygen demand of aerobic microorganisms in a reactor on normal life activities; the recycling of the gas in the greenhouse is realized. The greenhouse heating, the fertilization cost and the energy consumptionare reduced, and resources are saved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a biological fertilizer production device, in particular to a controllable biological fermentation device in a greenhouse. Background technique [0002] Greenhouses occupy an important position in my country's agricultural production and have a vital impact on my country's rural economic development. However, in some areas in northern my country, there is low temperature and little sunshine in winter, and there are also low temperature weather in early spring. Due to the closed nature of the greenhouse, indoor CO 2 Insufficient, resulting in a significant slowdown or even stop of greenhouse production, low land utilization, affecting the development of agricultural economy. [0003] Aerobic composting is under the condition of good ventilation and sufficient oxygen supply, with the help of the life activities of aerobic microorganisms to degrade organic matter, release heat, and prod...
