Method and device for drying easily-dried wood

Abstract

The invention discloses a method and device for drying easily-dried wood. The method for drying the easily-dried wood comprises the steps of wood accumulating, temperature rise preheating, temperature rise drying, constant-temperature drying, temperature reducing drying and cooling drawing. The device for drying the easily-dried wood comprises a drying kiln body, and a drying kiln body gate is arranged on the drying kiln body. The device for drying the easily-dried wood further comprises a ventilation and dehumidification system, a heating system, a detection and control system and a saturated steam generator. A wood accumulating area is arranged in the drying kiln body. An air inlet capable of being opened or closed is formed in the drying kiln body. The ventilation and dehumidification system, the heating system and the saturated steam generator are all communicated with the wood accumulating area. The detection and control system is used for detecting drying parameters in the drying kiln body and electrically connected with the ventilation and dehumidification system, the heating system, the saturated steam generator and the air inlet. The method and device have the beneficial effects of being high in drying speed, low in energy consumption, small in pollution to environment and the like.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a drying method and device for easy-drying wood. Background technique [0002] Drying is an important process in wood processing. The energy consumption during drying accounts for about 40-70% of the total energy consumption in wood processing, and the quality of drying directly determines the utilization rate of wood and the quality of wood products. [0003] At present, conventional steam drying is widely used due to its advantages of mature technology and large loading capacity, and is the most important wood drying method in the prior art. However, this method has defects such as low energy utilization rate, slow drying speed, and long drying time. Moreover, in the process of drying wood by this method, it is necessary to discharge dry exhaust gas to the outside, which will cause a certain degree of pollution to the environment. This shortcoming is particularly prom...

Problems solved by technology

[0003] At present, conventional steam drying is widely used due to its advantages of mature technology and large loading capacity, and is the most important wood drying method in the prior art. However, this method has defects such as low energy utilization rate, slow drying speed, and long drying time. Moreover, in the process of drying wood by this method, it is necessary to discharge dry exhaust gas to the outside, which will cause a certain degree of pollution to the environment. This shortcoming is particularly prominent in the drying operation of easy-to-dry sawn timber and veneer.
