Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment, the present invention is further described:

[0026] like Figure 1 to Figure 5 As shown, a heatable drum type aerobic composting reactor of the present invention comprises a horizontally arranged cylindrical body 1, the cylindrical body 1 is made of stainless steel or plexiglass, the diameter of the cylindrical body is 300 cm, the length is 500 cm, the wall thickness is 10 cm, and the cylindrical body 1 is 1. There is a layer of insulation layer 7 on the outer side, and the material of the insulation layer 7 is polystyrene or foamed asbestos to ensure that the temperature in the cylinder body 1 meets the requirements; the cylinder wall of the cylinder body 1 is provided with a feed port 2 and a discharge port 3 , the feed port 2 and the discharge port 3 are close to the two ends of the cylinder 1, the feed port 2 and the discharge port 3 are symmetrically distributed in the center of the cylinder body 1, an...

Abstract

The invention discloses a heatable drum-type aerobic compost reactor which comprises a barrel body arranged horizontally, wherein a feeding hole and a discharging hole are formed in the barrel wall ofthe barrel body and are distributed symmetrically in the center of the barrel body; an air inlet pipe and an air outlet pipe are respectively arranged at the two ends of a central line of the barrelbody; the air inlet pipe is connected with the air outlet pipe; a rubber plug is arranged between the air inlet pipe and the air outlet pipe; a plurality of air inlet branch pipe groups are also arranged on the air inlet pipe and in the barrel body; a plurality of shoveling plate groups are arranged on the inner circumferential surface of the barrel body in the direction of the inner diameter; theshoveling plate groups are arranged at intervals, and every two adjacent shoveling plate groups are arranged in a dislocation mode; a blower device is arranged an air inlet of the air inlet pipe; a tail gas treatment device is arranged at an air outlet of the air outlet pipe. According to the reactor, the problems that compost is difficult to stir and mix and poor in mass and heat transfer can besolved, and key parameters can be monitored, so that the compost efficiency is effectively improved.

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 drawbacks, such as long composting cycle, large area, poor hygiene, Odors, etc. will occur. With the continuous improvement of composting technology, many composting reactors have been developed at home and abroad. According to the ventilation mode, stirring and shape characteristics of the reactor, they can be divided into passive ventilation reactors, forced ventilation unstirred reactors, and forced ventilation with stirring reactions. and drum reactors. At present, different types of stirring paddles are generally used for stirring in the current reactor. This form ...
