Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0027] Such as Figure 1 to Figure 5 Shown, a kind of heatable roller type aerobic composting reactor of the present invention comprises the cylinder body 1 that horizontally arranges, and cylinder body 1 is made of stainless steel or plexiglass, cylinder body diameter 300cm, long 500cm, wall thickness 10cm, cylinder body 1. There is a layer of insulation layer 7 on the outside. The material of the insulation layer 7 is polystyrene or foamed asbestos to ensure that the temperature in the cylinder 1 meets the requirements; the cylinder wall of the cylinder 1 is provided with an inlet 2 and an outlet 3 , the feed port 2 and the discharge port 3 are close to the two ends of the cylinder body 1, the feed port 2 and the discharge port 3 are symmetrically distributed in the center of the cylinder body 1, and the positions are opposite to each other. The diameter of...

Abstract

The invention discloses a heatable drum-type aerobic composting reactor, which comprises a horizontally arranged cylinder body, the cylinder wall of the cylinder body is provided with a feeding port and a discharging port, the feeding port and the discharging port are Symmetrically distributed in the center of the cylinder body; the two ends of the center line of the cylinder body are respectively provided with an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are connected and a rubber plug is arranged between the two, and the air inlet pipe is There are also a number of intake branch pipe groups located in the cylinder body; a number of copy plate groups are arranged on the inner peripheral surface of the cylinder along the inner diameter direction, and the copy plate groups are arranged at intervals and are arranged in dislocation; A blowing device is arranged at the air inlet, and a tail gas treatment device is arranged at the air outlet of the air outlet. The invention can solve the problems of difficulty in stirring and mixing compost, poor mass transfer and heat transfer, and can monitor key parameters, thereby effectively improving the compost efficiency.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of organic solid waste, and in particular relates to a heatable drum type aerobic composting reactor. Background technique [0002] Composting technology is widely used in the harmless treatment of livestock and poultry manure, kitchen waste, crop straw and other wastes. The traditional composting process has certain disadvantages, such as long composting cycle, large floor area, poor sanitation, Odor etc. will be produced. With the continuous improvement of composting technology, many composting reactors have been developed at home and abroad. According to the ventilation mode of the reactor, whether there is stirring or not, and the appearance characteristics, it can be divided into passive ventilation reactor, forced ventilation without stirring reactor, and forced ventilation with stirring reaction. and drum reactors. The current reactors generally use different types of stirrin...
