Industrial dehumidifiers; Industrial dryers for heating and dehumidifying

Abrégé

A system is disclosed for drying a material to liberate a substance such as a liquid having a vapor pressure from solids and/or dissolved substances in the material. The system includes a plenum chamber and a blower providing a stream of air to the plenum chamber. An outlet communicates with the plenum chamber and a velocity accelerator is disposed downstream of the outlet. The velocity accelerator is arranged to receive air from the outlet of the plenum chamber into a progressively narrowing interior passageway terminating at a downstream choke point orifice. The choke point orifice discharges into a larger diameter discharge region. A throttle body is disposed in the discharge region and is selectively movable toward and away from the choke point orifice to decrease or increase the volume of the discharge region. A passageway is formed through the throttle body for receiving flashed material from the discharge region and conveying the material in a downstream direction. Also disclosed is a system for drying materials contained within a processing vessel wherein flash generators with vacuum throttles are used to maintain drying conditions within the vessel and to remove liberated substance from the processing vessel.

Methods and systems are disclosed for drying a material or, more generally, flash evaporating a target substance having a vapor pressure threshold. The methods and systems include a conveyor conduit that receives material and within which a pressure is established that is greater than the vapor pressure threshold of the target substance. The material moves through the conveyor and is expelled into a pressure drop zone created by one or more venturi nozzles. The pressure in the pressure drop zone is far less than the vapor pressure threshold of the target substance. As the material encounters the pressure drop zone, the targeted substance in the material experiences a rapid and extreme pressure drop and simultaneously a rapid temperature increase. This causes the target substance in the material to flash evaporate virtually immediately. The resulting vapor is separated from the remaining material and the now dry material is collected for further processing or use. The vapor can be collected, condensed, exhausted, or otherwise treated depending upon the goals of a particular installation or process. The methods and systems are particularly useful for drying water from moisture laden material such as coal wash fines.
