Description

Technical Field

[0001] The utility model relates to the technical field of heat energy supply, and more specifically, to a heat energy supply system for wood shavings drying. Background Art

[0002] The wood shavings drying heat energy supply system uses equipment such as combustion furnaces and heat pumps to efficiently provide heat energy, providing the necessary heat for the wood shavings drying process. This heat helps the moisture in the wood shavings evaporate quickly, thus achieving the desired drying effect.

[0003] A search of existing public documents revealed that patent publication number CN113144798A discloses a particleboard drying exhaust gas treatment process. This process involves funneling the flue gas after it passes through a drying cyclone into a single duct. This process features multiple steps of flue gas cooling and multi-stage cyclone dust removal, while also allowing for water circulation throughout the entire process, effectively utilizing resources. The use of multiple cooling channels in one water pipe, combined with mud and water separation, further conserves resources. This addresses the current issues with particleboard exhaust gas treatment, which typically involve fewer steps, poor flue gas cooling and harmful substance removal, and a low recycling rate throughout the process, resulting in wasted resources. However, this process has the following drawbacks.

[0004] During the shavings drying process, although heating is required to achieve heat supply operation, it is difficult to achieve large-scale displacement and oxygen supply in the combustion area during the heating process, resulting in low heating and combustion efficiency, difficulty in achieving sufficient oxygen supply and combustion, and poor drying heat energy supply effect. Therefore, a shavings drying heat energy supply system is needed. Utility Model Content
