Matrix fermentation device with interlayers, chimneys and movable bottom doors, and application

Abstract

The invention discloses a matrix fermentation device with interlayers, chimneys and movable bottom doors, and application thereof. The device is of a steel barrier type frame structure, which is formed by a frame opening (1), a frame body (2) and a frame bottom (3). The device is characterized by further comprising the interlayers (4), the chimneys (5) and the movable bottom doors (6); the interlayers (4) are double-sided zinc coating steel wire mesh plate at intervals being 50 to 80mm arranged in the middle of the device, divide the device into 2 to 4 silos, and form hollow aeration layers; the chimneys (5) are arranged in the separated silos and are 4 to 6 hollow ventilated cylindrical holes penetrating through the frame opening (1) and the frame bottom (3); the movable bottom doors (6)are arranged on the bottom part of the device and comprise two movable doors so as to be convenient to discharge. The device adopts the mesh plate hollow interlayers and the chimneys to naturally ventilate; when the device is applied to carry out matrix fermentation, one-time stirring-free static fermentation and semi-automatic discharging through the movable bottom plates can be realized, so thatthe device is convenient to use and good in effect. The device is made of steel materials so as to be reasonable in structure and long in service life, and can be multilayer stacked, so that a fermentation space is saved, and the device is particularly suitable to be applied to industrial solid waste raw material fermentation treatment carried out by matrix production enterprises.

Description

technical field [0001] The invention relates to a solid organic waste fermentation device and its application, in particular to a substrate fermentation device with an interlayer, an air chimney and a movable bottom door and its application, belonging to the technical field of biological fermentation engineering. Background technique [0002] Substrate fermentation (composting) is a traditional and quite modern biotechnology, and it is also a comprehensive and highly applicable engineering science. The purpose of fermentation is to turn all kinds of industrial and agricultural organic waste into a stable, harmless organic waste suitable for soilless cultivation and environmental restoration through a series of scientific process steps and convenient and practical fermentation equipment. Matrix products. Modern fermentation (composting) technology is developed on the basis of traditional anaerobic composting in rural areas, and is constantly innovating and improving in pract...

Problems solved by technology

[0003] 1. Strip-stack fermentation (composting)—it provides oxygen to the pile through mechanical or manual regular turning or forced ventilation. The fermentation scale is small, it occupies a large area, the fermentation time is long, the production capacity is limited, the heat preservation performance is poor, and it is difficult to kill the pathogens in the stockpile

In the early stage of fermentation, it is easy to emit a strange (smelly) smell; in the later stage of aging (drying), the dust is flying when the pile is turned, and the open fermentation site is full of sewage in rainy days, which is easy to breed mosquitoes and flies

[0004] 2. Static fermentation (composting)——Compared with strip-stack fermentation, the difference is that during the fermentation process, materials are not turned over, but mechanically forced ventilation is used to aerate or induce air extraction. Its characteristics are similar to those of strip-stack fermentation Approximately, the disadvantage is that the ventilation rate and the temperature of the pile are difficult to control. If the ventilation rate is too small, anaerobic formation in the pile will easily cause the temperature to be too low or too high, which will affect the maturity of the compost, and even need to be matured for a second time. Fermentation, especially during forced ventilation, emits a strange (stinky) smell, and deodorization facilities are required, which will inevitably increase investment and affect operating costs

[0005] 3. Trough fermentation (composting) - the fermentation process takes place in a long and narrow channel called a "trough". The track is set above the wall of the trough to facilitate the movement of the turning machine, and the bottom of the trough is laid with aeration The pipeline can ventilate and aerate the pile. It is a fermentation system that combines controllable ventilation and regular turning. It is characterized by a high degree of mechanization, a small footprint, a short fermentation cycle, and uniform fermentation quality. A lot of equipment and facilities, large investment in construction, high operating costs

[0006] 4. Reactor fermentation (composting) - the type of fermentation system is mostly large-scale equipment and facilities, which are widely used abroad and rarely imported in China

[0007] To sum up, regardless of the type of fermentation (composting), more mechanical power and energy consumption are required, as well as environmental protection facilities for the treatment of three wastes. For this reason, more fermentation equipment, depreciation expenses and operating costs will inevitably be added , due to the excessive investment in the construction period of substrate enterprises, the high cost of production and operation, and the lagging process technology, the market prices of substrate and organic fertilizer products remain high

Many farmers cannot afford organic fertilizers and substrate products, and can only choose to use chemical fertilizers, which restricts the development of substrate enterprises to a certain extent, affects the application and promotion of organic fertilizers and substrate products, and in turn restricts organic fertilizers. The process of ecological agriculture
