Ventilation and heat exchange system for granary

Abstract

The invention discloses a ventilation and heat exchange system for a granary. The system comprises an exhaust fan, a suction fan and a ventilation duct; the ventilation duct comprises outer ring air ducts, inner ring air ducts and support rods used for connecting and supporting duct bodies; the inner ring air ducts are located in a space formed by the outer ring air ducts in an enclosing mode; one end of the ventilation duct is connected with the exhaust fan, and the other end of the ventilation duct is connected with the suction fan. The ventilation and heat exchange system has the advantages that rapid cooling can be conducted on inner layer stored-grains.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a ventilation heat exchange system for a granary. Background technique [0002] At present, traditional logistics granaries or industrial large-scale granaries used to store granular grains, such as granaries used to store plastic grains, feed grains, rice, rice, soybeans, corn and other granular grains, mostly adopt single design , can only store one kind of grain at the same time, and has a single function. There are also some logistics granaries that adopt a double-body design, but use two sets of separate grain unloading devices to unload grain, resulting in the disadvantages of occupying a large area and high cost. In addition, the current level of informatization in traditional granaries is low, and it is impossible to conduct effective and timely detection and monitoring of grain storage in granaries, especially deep storage grains, resulting in slow dis...

[0002] At present, traditional logistics granaries or industrial large-scale granaries used to store granular grains, such as granaries used to store plastic grains, feed grains, rice, rice, soybeans, corn and other granular grains, mostly adopt single design , can only store one kind of grain at the same time, and has a single function

There are also some logistics granaries that adopt a double-body design, but use two sets of separate grain unloading devices to unload grain, resulting in the disadvantages of occupying a large area and high cost

In addition, the current level of informatization in traditional granaries is low, and it is impossible to conduct effective and timely detection and monitoring of grain storage in granaries, especially deep grain storage, resulting in slow discovery of harm and difficult remediation.

In addition, the ventilation system of traditional granaries mostly uses surface heat exchange to cool down. When the grain storage is deep and the area is wide, it is difficult to quickly cool down the inner grain storage.
