摘要:
A chamber for absorbing condensate formed in a charge-air-cooler of a turbocharged engine system. The chamber may include desiccant to absorb the moisture. The chamber may also include a valve that is controlled by the vehicle control module to open to allow airflow to pass by the desiccant and absorb the moisture from the desiccant or to place in a closed position to allow the desiccant to absorb the condensate formed in the charge-air-cooler.

The invention relates to a dryer system for drying lignite coal used in a power plant. The system comprises a dryer and a closed loop heat pump circuit that is configured and arranged to provide heat energy to the dryer. The closed loop heat pump circuit includes a working fluid, a dryer heat exchanger, an expansion device fluidly connected and downstream of the dryer heat exchanger, arranged to enable heat energy transfer from the vapour of the second outlet line to the first working fluid and a compressor for compressing the working fluid.

A drying system includes a fluidized bed dryer and fluidizing gas loop. The system is a closed loop so that fluidizing gas used to dry particulate matter can be reconditioned and recycled to fluidize and dry additional particulate matter. The fluidizing gas is reconditioned by removing fine particulates and water vapor. The drying system includes oxygen control features to prevent oxygen from entering the system. A method for drying particulate matter includes fluidizing the particulate matter in a dryer with a fluidizing gas, heating the particulate matter to remove water, removing water vapor and fluidizing gas from the dryer, removing fines and water vapor from the fluidizing gas, recirculating the fluidizing gas to the dryer to fluidize additional particulate matter and removing dried particulate matter from the dryer. A modular drying system reduces the amount of construction necessary at the installation site.
摘要:
A system and method for at least partially drying seeds treated with a liquid. A supply of heated air is continuously fed to a drying chamber. Treated seeds enter one opening of the drying chamber and are forced around at least a portion of the internal perimeter of the drying chamber before exiting out a second opening. Another embodiment can treat the seeds during and/or after the seeds entering the drying chamber.
摘要:
An apparatus (1) and method for drying polymer powders is described. The apparatus has an inlet (2) and an outlet (3) for the polymer powder, heat registers (5) installed in the interior space (4) and lines (7) for a heated gas (6a) for drying the polymer powder. The lines open into the interior space (4) and are connected to heat exchangers (9) for heating gas (6). The heat exchangers (9) are connected to a plant for the preparation of 1,2-dichloroethane (15) and/or for the preparation of vinyl chloride from 1,2-dichloroethane so that thermal energy from the plant can be utilized for heating the gas (6). The method comprises treatment of a polymer powder with a heated gas (6a) in the drying apparatus (1).
摘要:
An apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. The fluidized bed also includes an opening for receiving a first fluidizing stream, an exit for fluidized particulate and at least one exit for non-fluidized particulate. A conveyor is operatively disposed in the fluidized bed for conveying the non-fluidized particulate to the non-fluidized particulate exit. A collector box is in operative communication with the fluidized bed to receive the non-fluidized particulate. There is a means for directing a second fluidizing stream through the non-fluidized particulate as while it is in the collector box to separate fluidizable particulate therefrom.
摘要:
A pre-drying system for lignite, including an inner heating fluid bed dryer including at least one built-in heat exchanger, a feeding device, a second discharging valve, and at least one stage of dust collecting device. The built-in heat exchanger is connected to saturated vapor, and to a condensate system. A fluid bed of the inner heating fluid bed dryer is connected to superheated vapor. Exhaust vapor of the inner heating fluid bed dryer is processed by the dust collecting device, and then a part thereof returns to the fluid bed, and another part thereof is evacuated.

摘要:
A flowable solid material, such as wet-milled corn germ, is continuously fed into the upper portion of a large vessel having a cylindrical shell with a vertical axis and a series of vertically spaced horizontal decks. Each deck has concentrically spaced annular zones of holes or perforations, and heated air from a set of blowers and a gas-fired or steam heat exchanger is forced countercurrently or upwardly through the perforations to produce a recirculating bed of material above each deck with an upward spouting flow of the material above the zones of perforations and a downward flow of material between the zones of perforations. The recirculating material forming the lower beds is also heated by cylindrical steam heat exchangers which extend vertically between the zones of perforations, and the material is fed progressively downwardly through the vessel to form the beds and for discharge from the lowermost bed. Sweep arms rotate above the decks and below the heat exchangers, and after the heated air flowing upwardly through the decks and beds absorbs moisture from the material, the air is exhausted to a dual cyclone separator. The separator collects solid particles within the exhaust air, and the clean exhaust air is directed from the separator back to the blowers to form a closed cycle operation. The apparatus may also be used for cooling, treating or burning a flowable solid material.
摘要:
A sand layer is fluidized by a gas stream or current in a fluidized bed dryer and indirectly heated by immersed stationary heat-exchanger tubes. The sludge to be dried is continuously fed under pressure in a pumpable conditon from above onto the fluidized sand layer. The sludge is coagulated in the fluidized sand layer to form sludge lumps. Here, the sludge lumps are successively dried from the surface down to the core thereof, and the already dried layers of the sludge lumps are successively abraded by the fluidized sand, whereby the sludge lumps are entirely comminuted and the dry matter thereof is pulverized to form dust. This product dust is continuously discharged together with the exhaust-gas stream from the fluidized bed dryer and continuously separated as a product from the exhaust-gas stream. The gas stream or current freed from dust is partially recycled in a closed circuit back to the fluidized bed dryer for fluidization of the sand layer.
