Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the intake and exhaust passages of the intake and exhaust system of the existing wood drying device are dispersedly arranged with multiple groups of intake and exhaust passages, the heat loss is large, and part of the humid air heated by the heater does not flow through the wood pile. It directly discharges out of the drying device, causing the problem of waste of heat energy, and then provides a forced centralized air intake and exhaust system for wood drying devices

specific Embodiment approach 1

[0012] Specific implementation mode one: as Figure 1-8 As shown, the forced centralized intake and exhaust system of the wood drying device in this embodiment includes a forward circulation exhaust fan 3, a forward circulation outer exhaust pipeline 5, a forward circulation outer air intake pipeline 10, and a forward circulation inner air intake pipe. Road 32, forward circulation internal exhaust pipeline 35, reverse circulation exhaust fan 4, reverse circulation external exhaust pipeline 6, reverse circulation external intake pipeline 9, reverse circulation internal intake pipeline 21, reverse circulation The exhaust outlet on the exhaust pipeline 18, the first partition 33, the second partition 20, the forward circulation exhaust fan 3 in the circulation is the first air outlet 2, and the exhaust outlet on the reverse circulation exhaust fan 4 The air port is the second air outlet 1, and one end of the positive circulation external exhaust pipeline 5 communicates with the f...

specific Embodiment approach 2

[0013] Specific implementation mode two: as image 3 As shown, the first separator 33 and the second separator 20 in this embodiment are both corrugated plates. Such a design can increase the surface area of ​​the first partition 33 and the second partition 20, and the heat exchange effect is good. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0014] Specific implementation mode three: as image 3 As shown, the first air intake hole 30 on the air intake pipeline 32 in the forward cycle and the second air intake hole 23 on the air intake line 21 in the reverse cycle are arranged opposite to each other in this embodiment. Such setting can ensure that the same humid air state can be obtained when the humid air in the device circulates forwardly or reversely. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The present invention relates to a forced central air intake and exhaust system of a wood drying device, which belongs to an air intake and exhaust system and aims to solve the problems of the existing wood drying device that the air intake and exhaust system comprises a plurality of groups of scattered air intake and exhaust channels, large heat losses can be caused, part of wet air heated by a heater does not flow through wood but is directly discharged out of the drying device, and thus heat energy is wasted. A forward circulating inner air intake pipeline and a forward circulating inner exhaust pipeline are arranged in parallel in the vertical direction, a space between the forward circulating inner air intake pipeline and the forward circulating inner exhaust pipeline is divided into two pipelines by a first baffle, a reverse circulating inner air intake pipeline and a reverse circulating inner exhaust pipeline are arranged in parallel in the vertical direction, and a space between the reverse circulating inner air intake pipeline and the reverse circulating inner exhaust pipeline is divided into two pipelines by a second baffle. The forced central air intake and exhaust system is applied in forced ventilation of the wood drying device.

Description

technical field [0001] The invention relates to an intake and exhaust system, in particular to a forced centralized intake and exhaust system used on a wood drying device. Background technique [0002] Wood drying is an indispensable and important production link in the production of various civil and industrial wood products. Conventional wood drying is currently the most commonly used wood drying production method. Conventional wood drying is to stack wood according to certain requirements in a conventional wood drying device equipped with forced air circulation system, heating and humidification system, intake and exhaust system, and detection and control system. The regularity flows through the heater and the surface of the wood, transfers the heat of the heater to the wood, and at the same time absorbs and mixes the moisture evaporated from the wood in the humid air and discharges it out of the device. In this process of heat exchange and water evaporation, in order to...
