石臘油高溫快速干燥木材裝置使用已經一年半了,根据这一年半的經验現在已有可能提出一些已为生产实踐証实了的建議。高溫干燥裝置的成套建筑物通常应包括:装金屬槽的干燥室的厂房(棚子),具有一定压力鍋爐的鍋爐房及灌注和貯存石臘油的貯油器。实际应用的經驗証明,干燥槽以下列尺寸为最优:長7公尺,寬1.5公尺,高2.2公尺。这种尺寸可以干燥标准長度(6.5公尺)的鋸材。置于干燥槽的木材体积为3.5公尺~3。一个这样的干燥槽一年的生产率約为2250公尺~3規定鋸材。大家知道,石臘油高溫干燥木材过程的特点是有泡沫产生,在干燥很湿而薄的鋸材时,泡沫的产生就特別激烈。例如,干燥原含水量70％、厚22公厘的薄板时,在开始干燥30分鐘后所形成泡沫層的厚度可以超过1
It has been a year and a half since the paraffin oil high-temperature rapid-drying wood installations were used. Based on this one-and-a-half year experience, it is now possible to put forward some suggestions that have been confirmed for production practice. Units for high-temperature drying installations should generally include: workshops (sheds) for drying rooms equipped with metal tanks, boiler rooms with a certain pressure boiler, and oil reservoirs for pouring and storing paraffin oil. Practical experience has proven that the drying tank is optimized for the following dimensions: 7 meters long, 1.5 meters wide and 2.2 meters high. This size can dry standard length (6.5 meters) of sawn timber. The volume of wood placed in the drying tank is 3.5 to 3 meters. One such drying trough has a productivity of about 2,250 meters per year and a specified sawn timber. As we all know, the high-temperature drying of paraffin oil is characterized by the production of foam. When drying very wet and thin sawn timber, the production of foam is particularly fierce. For example, when drying a sheet with an original moisture content of 70% and a thickness of 22 mm, the thickness of the foam layer formed after drying for 30 minutes may exceed 1
