Embodiment 1

[0019] see figure 1 and figure 2 , The reactor of the present invention includes a compost tank, a ventilation system, a stirring system and various sensors. In this example, the tank body is cylindrical and horizontal.

[0020] The top of the tank is provided with a sampling port 1 (two, located at both ends of the top of the tank), an exhaust port 2 and a feeding port 3, and a discharge port 4 is provided at the bottom of the tank. A base 6 is arranged under the tank, and a tank support 7 is installed on the base 6. The tank support 7 is supported on the central axis at both ends of the tank, and the tank is fixed by the base 6 and the support 7. On the bottom surface of the base 6 Casters 5 are installed to increase its mobility.

[0021] The ventilation system is composed of fan 8, valve 9, flowmeter 10 (glass rotameter can be used) and ventilation pipe 11 connected successively with conduits. There are three ventilation pipes, which are respectively located at the bot...

Abstract

The invention provides a composting reactor including a composting tank. The top of the tank is provided with a feed inlet, a sampling port, an air outlet and the bottom of the tank is provided with a feed outlet and the internal of which is provided with a stirring device, a moisture sensor, and an O2 sensor and the wall of which is provided with a ventilating pipe with a plurality of vents communicated with the internal of the tank. The air can be a pumped into the tank through a fan. The electrical signals received by the sensor can be transferred to a computer through a data collector and the computer realizes the recording, storing, calling and various analyses of the data. The composting reactor of the invention enables materials to mix evenly and improves ventilation and makes water evaporation easy and a full fermentation of the material. The reactor has no partial hypoxia or caking, and the fan can be artificially controlled, and the reactor can realize an online monitor and data management and can call the data for analysis at any time.

Description

technical field [0001] The invention relates to the field of solid fermentation, in particular to an aerobic composting reactor. Background technique [0002] With the increasing discharge of solid waste, the disposal of waste has become a major issue related to the ecological environment. As a treatment method for waste, composting technology has received more and more attention, and the corresponding composting equipment has developed rapidly. The aerobic composting reactor system has the advantages of high compost temperature, short fermentation time, thorough decomposition of organic matter, and effective prevention of the spread of pathogenic bacteria and odor emission. The difference of composting equipment is mainly reflected in the aspects of ventilation mode, whether there is stirring or not, and appearance characteristics. [0003] In addition to factory composting equipment, there are more and more examples of composting devices used in laboratories to study the ...
