摘要： A system and method for extracting waste heat from the exhaust (20) of a biomass dryer (14), such as in a grain alcohol plant (10). A boiler circuit (74) provides steam at a high pressure to a balance of the plant (64). A recovered energy circuit (76) extracts heat from the exhaust and provides steam (60) at an intermediate pressure, thereby eliminating the need for a pressure reducing valve in order to satisfy an intermediate pressure steam demand in the plant. Working fluids in the boiler and recovered energy circuits are intermixed in a boiler feed vessel (72).

摘要： Waste heat is extracted from the exhaust (20) of a biomass dryer (14) in a grain alcohol plant (10). A boiler circuit (74) provides high pressure steam to a balance of the plant (64). A recovered energy circuit (76) extracts heat from the exhaust via a dryer exhaust condensing economizer (24) and provides a steam mixture (60) to satisfy an intermediate pressure steam demand of the balance of the plant, thereby bypassing a portion of the boiler circuit. Working fluids in the boiler and recovered energy circuits are intermixed in a boiler feed vessel (72). Dryer exhaust condensate (30) may be used in an exhaust gas scrubber (22) upstream of the dryer exhaust condensing economizer to remove pollutants and to saturate (26) the exhaust gas for improved heat transfer. Heat transfer may be further improved by operating the dryer exhaust condensing economizer at an elevated pressure.

摘要： The present invention pertains to a method and an installation or system for drying fibrous material. The method comprises the step of ventilating very moist air through the fibrous material located in a drying zone. The moisture content of the moist air is less than that inside the drying zone, its pressure is close to atmospheric pressure and its temperature is higher than that of the material to be dried. The method additionally comprises the step of recovering the heat of condensation of the water vapor extracted from the fibrous material to heat the moist air, providing leaks between the outside ambient air and the ventilation circuit upstream and downstream of the drying zone, making possible a mass and heat exchange. It is possible to ensure heat and mass balance without expelling large amounts of moist air into the ambient air.

摘要： A process is disclosed for the recovery and reuse of heat contained in the wet exhaust gases emanating from a solids dryer or liquor concentrator, particularly one in which drying or concentration is facilitated by purging the vapor with some noncondensable gas such as air or nitrogen. Water or solvent vapor in the moist exhaust mixture is separated from the noncondensable gas or gases by preferentially passing the vapor through a semipermeable membrane. The water or solvent vapor is then compressed and subsequently condensed in a heat exchanger, permitting recovery of its latent heat of vaporization for reuse in the evaporation process. In a drying process, this recovered energy is conveniently used to reheat the dry gases that exit from the membrane separator, permitting the hot, dry gases to be recirculated through the dryer. Alternatively, an indirect heat exchanger may be used to transfer this heat to the material being dried. In an evaporative process for the concentration of a liquor, the recovered energy may be used either to preheat the dry purge gases or to heat the dilute liquor being concentrated.

摘要： An air drying unit for compressed air systems is provided. The air drying unit has a precooler/reheater, a main cooler and a moisture separator. Incoming air is cooled to cause moisture within the compressed air to condense, which is then separated to dry the compressed air. The precooler/reheater, main cooler and moisture separator are designed as an integral unit that does not require pipes to connect the components together. Instead, compressed air flows through the sealed unit through passages therein between the precooler/reheater, main cooler and moisture separator.

摘要： A tube dryer system is used to remove moisture from solid commercial products. The present apparatus includes a condensate vessel that separates condensed steam from excess steam. The excess steam is passed through a thermocompressor and combined with incoming fresh steam to produce a combined steam feed stream having a higher flow rate at only slightly reduced pressure and reduced superheat content, resulting in increased dryer capacity and reduced steam losses with no increase in energy costs.

摘要： This invention relates to a heated steam atmosphere drying system comprising dryer in combination with an exhaust recompression system which is extremely energy efficient and eliminates dangers known to air dryers. The system uses superheated steam as the drying medium, which recirculated through the system where its heat of evaporation and heat of compression is recovered, thereby providing a constant source of heat to the drying chamber. The dryer has inlets whereby feedstock and superheated steam are fed therein. High heat transfer and drying rates are achieved by intimate contact of the superheated steam with the particles being dried The dryer comprises a vessel which enables the feedstock and steam to enter recirculate together. When the feedstock becomes dry it will exit the dryer with the steam and become separated from the steam through the use of a curvilinear louver separator (CLS). The CLS enables removal of fine and ultrafine particles from the dryer. Water vapor separated from the particles in the CLS as superheated steam, may then be recovered and recirculated as steam through the use of a compressor to either directly or indirectly heat the dryer, and a heat exchanger or a heater to directly provide heat to the dryer. This system not only provides a very efficient heat transfer system but results in a minimum carry-over of ultrafine particles thereby eliminating any explosive hazard.
