摘要： Disclosed is a cabinet for storing containers of volatile hazardous liquids, the cabinet having therein, in a place out of the way of the containers stored therein, a vapor trap for adsorbing and/or neutralizing vapors of said liquids. The vapor trap may be fastened in the cabinet to be easily removed, and replaced, or to be chemically or mechanically recharged and then replaced. The trap has an outer perforate shell containing therewithin vapor trapping material such as a vapor adsorbing and/or a vapor neutralizing material. The material may be in loose, particulate form or may be carried in one or more fiber sheets. The shell may be of rectangular box shape or of right-triangular box shape, to enhance positioning the vapor trap in the cabinet in a place out of the way of the containers. The vapor trapping material may be activated carbon, impregnated or unimpregnated, and/or may be slaked lime or activated alumina.

摘要： An improved hopper drier for drying granular material of synthetic resin to supply it to a molding machine. The hopper drier includes two dehumidifying columns which are arranged such that dry air dehumidified in one of the dehumidifying columns at a lower temperature is delivered to a heating pipe spirally wound round the heating column disposed adjacent to the hopper drier housing. After air is preheated in the heating pipe, it is mixed with waste air coming from the hopper drier housing and the mixture is then heated in the heating column. While the one dehumidifying column is operated under normal working conditions, the other dehumidifying column is supplied with a part of the dehumidified air flowing from the one dehumidifying column so as to dry dehumidifying material held in the other dehumidifying column. When it is detected that the one dehumidifying column has reduced dehumidifying capability, a shifting operation is carried out immediately so that air dehumidified in the other dehumidifying column is delivered to the heating pipe.

摘要： A method and apparatus for freeze drying heat sensitive aqueous products on a continuous basis, utilizing molecular sieves to sequester the sublimating water vapor, is described. At least two beds of sieve are used sequentially, one being heat regenerated while another is actively adsorbing condensable vapors. Exotherm is controlled during freeze drying, and bed regeneration may be accomplished without the use of a purge gas. The advantages of certain types and sizes of molecular sieves, in a continuous freeze drying procedure, is discussed.

摘要： A counter-current absorption process for the dehumidification of moist air or saturated water vapor is described. The absorption liquid used in said process consists of an aqueous solution of one or more non-volatile components. The absorption is carried out adiabatically, that is without substantial heat exchange with the surroundings, and with weight proportions between the absorption liquid and the gas or vapor such that most of the condensation heat of the water vapor condensed during the absorption is transferred to the gas or vapor becoming progressively drier, to thereby raise the temperature thereof. The diluted absorption liquid is concentrated by evaporation and is then recycled for reuse. The demoisturized and heated air or vapor is used e.g. in a drying process and is then recycled to the absorption device.

摘要： This invention relates to the use of desiccants in conjunction with an openoop drying cycle and a closed loop drying cycle to reclaim the energy expended in vaporizing moisture in harvested crops. In the closed loop cycle, the drying air is brought into contact with a desiccant after it exits the crop drying bin. Water vapor in the moist air is absorbed by the desiccant, thus reducing the relative humidity of the air. The air is then heated by the used desiccant and returned to the crop bin. During the open loop drying cycle the used desiccant is heated (either fossil or solar energy heat sources may be used) and regenerated at high temperature, driving water vapor from the desiccant. This water vapor is condensed and used to preheat the dilute (wet) desiccant before heat is added from the external source (fossil or solar). The latent heat of vaporization of the moisture removed from the desiccant is reclaimed in this manner. The sensible heat of the regenerated desiccant is utilized in the open loop drying cycle. Also, closed cycle operation implies that no net energy is expended in heating drying air.
摘要翻译： 本发明涉及干燥剂与开环干燥循环和闭环干燥循环的结合，以回收在收获的作物中汽化水分中消耗的能量。 在闭环循环中，干燥空气在离开作物干燥箱后与干燥剂接触。 潮湿空气中的水蒸汽被干燥剂吸收，从而降低了空气的相对湿度。 然后将空气用所使用的干燥剂加热并返回到料仓。 在开环干燥循环期间，使用的干燥剂被加热（可以使用化石或太阳能热源）并在高温下再生，从干燥剂驱动水蒸汽。 在从外部来源（化石或太阳能）加入热量之前，这种水蒸汽被冷凝并用于预热稀（干）干燥剂。 以这种方式回收从干燥剂中除去的水分的蒸发潜热。 再生干燥剂的显热用于开环干燥循环。 此外，封闭循环操作意味着在加热干燥空气中不消耗净能量。

摘要： A by-pass valve for a gas drying system is mounted on a blower for flowing gas through the system. The by-pass valve comprises an inlet aligned with the inlet of the blower, an outlet aligned with the outlet of the blower, and a by-pass port connecting the inlet and the outlet of the valve. The cross-sectional area of the by-pass port is adjustable by movement of a restricting member into and out of the port. The gas pressure at the outlet of the blower and the gas flow rate leaving the blower can be varied by adjusting the position of the restricting member in the by-pass port to divert or prevent diversion of some of the gas at the outlet of the blower. The gas thus diverted from the gas drying system is recirculated through the blower to thereby minimize additional gas required at the blower inlet to meet the gas flow requirement of the system receiving the dried gas.
