Multi-stage bubble-column vapor mixture condenser

摘要

A multi-stage bubble-column vapor mixture condenser comprises at least a first stage and a second stage. Each stage includes a carrier-gas inlet and a carrier-gas outlet, as well as a condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet. The carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage.

1. A multi-stage bubble-column vapor mixture condenser, comprising:
at least a first stage and a second stage, wherein each stage includes:
a carrier-gas inlet;a carrier-gas outlet; anda condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet, wherein the condensing bath has a substantially constant temperature from top-to-bottom of the bath, wherein the carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath, wherein the carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage; a source of coolant; and a conduit passing from the coolant source through the condenser chamber of each stage of the bubble-column vapor mixture condenser, wherein the coolant source and the conduit are configured to direct coolant through the conduit in counterflow to carrier-gas flow through the condenser to recover energy from condensation.
