Embodiment 1

[0041] The integrated intelligent membrane aerobic fermentation system includes: fermentation chamber 1, winding film machine 18, semi-permeable membrane 2 wound on winding film machine 18, membrane method robot 3, winding film machine 18 can be installed in the fermentation chamber 1 is used to move the semi-permeable membrane 2, and the semi-permeable membrane 2 is used to seal the fermentation raw materials placed in the fermentation chamber 1. The semi-permeable membrane 2 is composed of three layers of materials, and the material of the middle layer is expanded polytetrafluoroethylene. The material is distributed with micron-level pores (0.2 μm in diameter), and the inner and outer layers are made of polyester fiber, which has good tensile, radiation and corrosion resistance. A membrane robot for turning and throwing fermentation raw materials is provided below the film winding machine.

[0042] The fermentation bin 1 is rectangular, and the wall is filled with heat-insul...

Embodiment 2

[0052] According to a kind of integrated intelligent membrane method aerobic fermentation method provided by the present invention, comprises the following steps:

[0053] 1) loading the fermentation raw materials into the fermentation bin 1 through the feed port 11 of the fermentation bin 1;

[0054] 2) Open the winding film machine 18, and the winding film machine 18 moves from one end to the other end on the slide rail 7 for laying the semi-permeable membrane 2 on the slide rail 7, and the film pressing device 17 is opened to combine the semi-permeable membrane 2 with the Slide rail 7 is sealed;

[0055] 3) In the control system 6, set the aeration mode, the throwing interval of the membrane robot 3, the feedback interval of each sensor, the pressure limit value and the discharge temperature, and start this fermentation. It is preferable to adopt a multi-sensor and multi-region joint feedback adjustment mode, that is, temperature-oxygen-pressure-humidity-sub-area joint fee...

Abstract

The invention provides an integrated intelligent membrane method aerobic fermentation system and method. The system comprises a fermentation bin, a membrane winding machine, a semi-permeable membrane wound on the membrane winding machine, and a membrane method robot, wherein the membrane winding machine can move in the fermentation bin and is used for paving and winding the semi-permeable membrane, the semi-permeable membrane is used for sealing fermentation raw materials placed in the fermentation bin, and the membrane method robot for turning and throwing fermentation raw materials is arranged below membrane winding machine. According to the invention, the mechanization and intelligence degree of the film covering fermentation technology can be further improved, the manpower cost is greatly reduced through the film winding machine and the film method robot, and the fermentation state of each region of the pile body can be mastered in real time; the ventilation rate and time length are intelligently adjusted through the control system, and the professional requirements of managers are reduced; harmful gas emission in the fermentation process is further reduced through under-film turning and secondary filtration of gas outside the film, and the environmental protection performance of the film covering fermentation technology is improved.

Description

technical field [0001] The invention relates to the technical field of waste harmless treatment, in particular to an integrated intelligent membrane aerobic fermentation system and method. Background technique [0002] The fertilizer utilization of biomass resources is one of the effective ways to solve the problems of large output, difficult utilization and heavy pollution of livestock and poultry manure, crop straw and sludge. Aerobic fermentation technology is a common main technology in the process of fertilizer utilization. At present, the stack type and tank type are mainly used. It has low investment and large processing capacity, but it is easy to cause secondary pollution during the fermentation process. The ammonia gas produced , hydrogen sulfide and other odors and greenhouse gases such as methane and nitrous oxide are directly discharged into the atmosphere. development trend. [0003] Membrane-covered aerobic fermentation technology is widely used in aerobic c...
