摘要： A drying apparatus for a strip of material or web, including a conditioning zone (3) immediately following but fully integrated with the dryer (6), to lower the bulk temperature of the web. The web of material can be introduced to conditioned air which is substantially free of contaminants being evolved from the coating on the web. The temperature of the conditioned air is low enough to absorb heat from the web, effectively lowering the solvent evaporation rate, and can be controlled such that it is greater than the dew point of the contaminants being evolved from the web, thereby mitigating condensation that normally forms and visible vapours that form outside of the dryer enclosure (6). Pressure control is provided in the conditioning zone (3) so that solvent vapours will not escape and so that ambient make-up air can be regulated as required. Gas sealing between the conditioning zone (3) and the dryer (6) prevents hot, solvent vapour laden air from the dryer from escaping into the conditioning zone (3).

摘要： A dryer (10) used to remove a flammable solvent or vapors from a traveling web of material (12) or the dryer. The dryer (10) consists of a chamber which is preferably a large metallic cylinder (14) through which the web of material (12) moves longitudinally. Seals (16,18) in the metallic cylinder at the points of entry and exit of the traveling web permit the control system to maintain the desired environment under controlled pressure within the metallic cylinder. The web of material travels successively through one or more zones within the metallic cylinder. At each zone, the web of material is exposed to a pressurized atmosphere which may be at increasingly higher temperatures. The solvent is recovered from the pressurized atmosphere by rapid cooling, membrane separation or absorption. Sensors within each zone measure the oxygen content of the pressurized atmosphere. If the oxygen content exceeds a given threshold, pressurized nitrogen or other inert gas is added. Through the use of a carbon bed (60) at the last zone, the pressurized atmosphere from that zone is rendered sufficiently free of solvent to be exhausted to the air or a nitrogen recovery unit, thereby maintaining the desired overall pressure within the metallic cylinder.

摘要翻译：用于工业干燥器的控制系统，用于从材料或干燥器的移动网状物中除去可燃溶剂或蒸汽。该干燥机包括一个室，其优选地是一个大的金属圆筒，材料幅材通过该金属圆筒纵向移动。在金属圆筒中在行进网的入口和出口处的密封允许控制系统在金属圆筒内的受控压力下保持期望的环境。材料网连续通过金属圆筒内的一个或多个区域。在每个区域，材料网暴露于可能处于越来越高的温度的加压气氛。通过快速冷却，膜分离或吸收从加压气氛中回收溶剂。每个区域内的传感器测量加压气氛的氧气含量。如果氧含量超过给定阈值，则加入加压氮气或其他惰性气体。通过使用最后一个区域的碳床，来自该区域的加压气氛被充分地没有溶剂排出到空气或氮气回收单元，从而保持金属圆筒内所需的总体压力。
