Abstract

The invention provides a wet wood shaving drying process and drying system. The drying system comprises a boiler, a mixing chamber, hot flue gas cyclone separators, an ash discharge screw conveyor, aone-way feed chute, a single-channel roller dryer, an unloading conveyor, a multi-pipe cyclone separator, a fine waste conveyor, a main induced draft fan and a bilateral control air valve. The temperature of high-temperature flue gas in the boiler is 680-780 DEG C. The temperature of the flue gas after air mixing and distribution is 350-450 DEG C. The oxygen content is 10-11%. The smoke dust content is 300-600 mg / m3. The wind speed of the single-channel roller dryer is 15-20 m / s. The temperature of clean flue gas is 320-450 DEG C. The rotating speed is 10-28 r / min. The outlet temperature is 100-120 DEG C. The drying system provided by the invention is reasonable in structure. The drying effect of the drying process is good. Operation is easy to control. Fire factors are eliminated. The fire rate is reduced. The problem of safety in the existing drying process is solved.

Description

technical field [0001] The invention belongs to the technical field of plate drying, and in particular relates to a drying process of wet shavings and a drying system thereof. Background technique [0002] As we all know, the raw materials of OSB boards are mainly soft needles, small diameter wood of broad-leaved trees, fast-growing thinning wood, etc., such as eucalyptus, fir, poplar thinning wood, etc., which have a wide range of sources and can be made into large panels. The geometrically shaped flakes are dried, glued, orientated and thermoformed. Oriented strand board (OSB) is a flat-pressed particle board made of shavings arranged in a certain direction during paving. Due to the large shape of the shavings, generally oriented strand boards have high requirements on the size and specifications of the raw materials, and are generally planed from small-diameter lumber through long wood shavings, drum shavings, and disc shaving machines. [0003] The shavings have the fo...
