specific Embodiment approach 1

[0025] Specific implementation mode one: combine figure 1 As shown, the film-lined container type fermentation device of the present embodiment includes a container door 1, a waterproof breathable membrane 2, a blower 3, an air inlet pipe 4, a perforated air pipe 5, a temperature detector 6, an air outlet pipe 7, and a container 8; 8 is provided with a perforated air pipe 5 at the bottom, a waterproof breathable membrane 2 is arranged on the upper part of the container 8 and extends to the bottom of the container door 1, an air outlet pipe 7 is arranged on the upper part of the waterproof breathable membrane 2, and a blower 3 and a temperature detection device are arranged on the lower part of the waterproof breathable membrane 2 Device 6.

[0026] In the waterproof and breathable membrane 2 in this embodiment, since small water droplets cannot pass through the waterproof and breathable membrane, the lower surface of the waterproof and breathable membrane contains a large numb...

specific Embodiment approach 2

[0029] Specific embodiment two: the present embodiment utilizes the method for composting by the above-mentioned film-lined container-type fermentation device, and proceeds according to the following steps:

[0030] Utilize the method for composting in the above-mentioned membrane-lined container type fermentation device, carry out according to the following steps:

[0031] 1. Stack the organic solid waste at the bottom of the membrane-lined container-type fermentation device at a height of 120-250 cm, and close the container door;

[0032] 2. When the temperature in the container 8 is lower than 65°C, turn on the blower 3 for intermittent ventilation, and stop for 15-45 minutes after every 15-45 minutes of ventilation. When the temperature in the container 8 is higher than 65°C, continue to ventilate until the temperature is lower than 50~55℃, the fermentation tail gas is discharged;

[0033] 3. After 10 to 15 days of fermentation, the fermented organic solid waste is taken ...

specific Embodiment approach 3

[0034] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the film-lined container-type fermentation device described in step one can also be a plurality of film-lined container-type fermentation devices placed side by side, connected in series through the outlet pipe 7 together. Other steps and parameters are the same as those in Embodiment 1.

[0035] Although the floor space of this embodiment is slightly larger, it is especially suitable for use under the condition of lack of container handling equipment, saving manpower and material resources, and reducing energy consumption.

[0036] In this embodiment, the air outlet pipe 7 introduces the fermentation tail gas in the first film-lined container-type fermentation device into the second film-lined container-type fermentation device, and preheats the low-temperature material by blasting, thereby reducing the heating time of the material and shortening the temperature. Comp...

Abstract

The invention discloses a membrane lining container type fermentation device and a compost and deodorization method using the same, and relates to a compost device and a compost and deodorization method using the device. The problems that an existing container type compost mode is high in operating cost, an existing biological filter is inconvenient to move and the construction period is long can be solved. The device comprises a container door, a waterproof and breathable membrane, an air blower, an air inlet pipe, a perforation breather pipe, a temperature detector, an air outlet pipe and a container body. The method includes the steps that first, materials are put in; second, when the temperature is lower than 60 DEG C, intermittent ventilation is conducted; when the fermentation temperature is higher than 60 DEG C, continuous ventilation is conducted, and fermentation tail gas is exhausted; third, the materials are taken out after being fermented for 10-15 days. According to the membrane lining container type fermentation device, the body is improved from a container or a waste container, equipment is simple and convenient to use, waste can be utilized, equipment cost is saved, and the construction period is short; the air blower is controlled to operate through time and temperatures, so that electric energy is saved; transportation is facilitated; occupied area is reduced obviously.

Description

technical field [0001] The invention relates to a composting device and a composting and deodorizing method using the device. Background technique [0002] Aerobic composting treatment means that solid waste and conditioner are fully mixed to form a material pile of a certain volume. Under aerobic conditions, a large number of microorganisms are used to rapidly degrade the organic matter and biological residues in the material, generate carbon dioxide and water, and release A large number of thermal biochemical processes. Existing composting methods mainly include strip stacking, static ventilation, trough, and reactor. Reactor type composting mainly includes silo type, tower type, drum type, stirring box type, circular stirring bed type, tunnel type, and container type. Container composting has the advantages of easy movement and modular operation. During the aerobic composting process, a large amount of ammonia, hydrogen sulfide and other odors will be produced, which w...
