Liquid deaerating apparatus

摘要

A liquid deaerating apparatus comprises a deaerating tank housing a spray-type deaerator. The latter has a spray nozzle means for spraying the liquid to be deaerated horizontally against a surrounding liquid spray impingement absorbing and contacting means. Below the latter there is disposed packed bed means through which the liquid passes to a collection area within the deaerating tank. The packed bed through whcih the liquid percolates to the collection area comprises a high flow rate system to assist such downward flow of the liquid and release of air and gas.
