Device for wood drying chamber heat energy recovery and VOC treatment

Abstract

The invention discloses a device for wood drying chamber heat energy recovery and VOC treatment. The device for wood drying chamber heat energy recovery and VOC treatment comprises an air inlet and outlet assembly, a heat exchange assembly, a VOC purification assembly and a discharge power assembly, wherein the air inlet and outlet assembly is connected with an air inlet and outlet of a drying chamber and the heat exchange assembly, the VOC purification assembly is connected with the heat exchange assembly and the discharge power assembly, and the heat exchange assembly is connected with the discharge power assembly. According to the device for wood drying chamber heat energy recovery and VOC treatment, the problem that an existing drying chamber is difficult to continuously exhaust moisture and gas under the working condition that a fan rotates at any direction is solved, the heat energy utilization rate in the wood drying process is greatly improved on the premise of guaranteeing the wood drying uniformity, grading treatment is carried out on VOC in waste gas generated in the drying process, and the device for wood drying chamber heat energy recovery and VOC treatment has the advantages of being simple in structure, low in cost, simple in operation method, small in installation difficulty and high in adaptability, can be used in a newly-built drying chamber, and can also be used for conducting energy-saving transformation on the existing drying chamber; the device can be widely applied to wood product manufacturing industries such as solid wood drying, wood product and artificial board processing and the like.

Description

technical field [0001] The invention belongs to the field of thermal processing of wood, and more specifically relates to a device for drying wood, in particular to a device for recovering heat energy and controlling VOC in a wood drying chamber. Background technique [0002] At present, further requirements are put forward for the upgrading and transformation of the wood product processing industry to environmental protection, energy saving, and green and clean production.
